Abstract
Description
Technical Field
[0001]
[0002] The present disclosure generally relates to compositions and methods for promoting mental health, particularly compositions derived from plant extracts or fungal extracts for use in calming, energizing or enhancing feelings of well-being or happiness in an individual.
Background Art
[0002]
[0003] The following discussion of the background of the invention is for the sole purpose of facilitating an understanding of the invention. It is to be recognized that no admission is made that any of the material referred to was published, known or part of the common general knowledge in any jurisdiction as of the priority date of the invention.
[0003]
[0004] Modern life can be highly stressful and extremely fatiguing. It is difficult for an individual to find ways to relax, unwind, energize and feel more well-being or happiness. Some individuals may use drugs or alcohol to achieve such feelings to some extent, but these can have an impact on the individual's health in the long term or are not legal in some cases.
[0004]
[0005] The recent COVID-19 pandemic has had a significant impact on people worldwide, not only physically but also in terms of their mental health. Due to the spread of the coronavirus, people were often unable to go out and were forced to stay at home for over two years. This restrictive lifestyle has raised concerns about its impact on individual mental health, including stress accumulation, anxiety, and depressive symptoms. The World Health Organization (WHO) reported a 25% increase in global prevalence of anxiety and depression in the first year of the COVID-19 pandemic. Numerous studies have investigated the psychological impact of COVID-19 on healthcare workers and the general public, reporting high levels of problems in these areas. The decline in mental health was found to be more severe among the general population than among healthcare workers and students. A meta-analysis of these studies reported pooled prevalence rates of 33% for anxiety and 28% for depression. Anxiety levels among university students were investigated in Malaysia (Irfan et al., The Psychological Impact of Coronavirus on University Students and its Socio-Economic Determinants in Malaysia. Inquiry. 2021; 58:469580211056217), and the results showed that 12.3% of students were normal, 30.5% experienced mild anxiety, 31.1% experienced moderate anxiety, and 26.1% experienced severe anxiety. A similar experiment was conducted in Thailand, where the COVID-19 pandemic negatively impacted anxiety symptoms among Thai students (Tiaprapong et al., PLoS One. 2021; 16(6): 2021). The study strongly supports evidence that Thai healthcare student workers were similar to students in other countries who exhibited significant sedentary behavior, weight gain, and decreased mental health.
[0005]
[0006] Mental health issues among healthcare workers include excessive stress and mental stress, long working hours, separation from family, lack of appropriate protective equipment in the work environment, and lack of effective treatment. Burnout levels and factors associated with distress among healthcare workers engaged in COVID-19 management in India were reported (Menon et al., PLoS One 2022;17(3)2022). The report found that 52.9% of those involved experienced distress. One study found that among seven middle-income Asian countries (China, Iran, Malaysia, Pakistan, the Philippines, Thailand, and Vietnam), Thailand reported the highest anxiety, depression, and stress scores (Wang et al., PLoS One 2021;16(2)2021). In contrast, the same report showed that Vietnam had the lowest average scores on the anxiety, depression, and stress scales.
[0006]
[0007] Extracts from Labisia pumila, also known as Kacipfatimah, are thought to be effective for female reproductive disorders (Chua et al., Fitoterapia, 83(8), pp. 1322-135, 2012; Zakaria et al., BioMed Res. International, 2021, 9928199). Lignosus rhinoceros, or tiger milk mushroom, is a medicinal fungus. Extracts from Scerotia have been used to treat asthma, cough, fever, liver-related diseases, and gastric ulcers (Chang and Lee 2004, Fungal diversity 15: pp. 15-22). Lignosus rhinosalas extract has been shown to possess antioxidant properties and neuroprotective properties in nematodes (C. elegans), which have led to its potential use in cancer treatment (Kittimonkolsuk et al., Pharmaceuticals 27;14(2):93, 2021).

[0053]
[0068] The following are non-limiting embodiments of the model. [Examples]
[0054]
[0069]
[0070] Example 1 Screening of plant extracts for neuronal cytotoxicity
[0071] This study screened natural products and nutritional supplements from Asia for compositions that may improve human mood and mental health. Among 23 tested samples, three showed significantly higher cell viability against rat hypothalamic nerve (R-hth-507) cells. Real-time PCR experiments showed that seven samples exhibited significant β-endorphin synthesis activity. These results suggest that the extracts have potential as candidate mental health drugs. Two of the most promising plant extracts were further studied.
[0055]
[0072] Sample preparation
[0073] Twenty-three natural product samples were ground and dissolved in MQ water at a concentration of 50 mg / mL for the first screening. The dissolved samples were thoroughly mixed by vortexing and sonicated for 5 minutes. This step was repeated six times. For the second screening and real-time PCR experiments, each sample was prepared at the different concentrations shown in [Table 1].
[0056]
[0074] First screening
[0075] To investigate the anti-stress activity derived from plant extracts, their activating activity against rat hypothalamic neurons (R-hth-507) was examined.
[0057]
[0076] cell culture
[0077] Rat hypothalamic neurons (R-hth-507) were purchased from Lonza Bioscience (Basel, Switzerland) and cultured in primary neuronal growth medium (PNGM) supplemented with Singlequots, which contains all the growth factors and nutritional supplements necessary for successful culture of rat and mouse neurons.
[0058]
[0078] Cell viability assay
[0079] The cytotoxicity of R-hth-507 was measured in vitro by a colorimetric method that measures the mitochondrial response to the dye 3-(4,5-dimethylthiazole-2-yl)-2,5-diphenyltetrazolium bromide (MTT), purchased from Tokyo Chemical Industry (Tokyo, Japan). Generally, the reduction of MTT occurs in metabolically active cells. Therefore, the level of activity is measured spectrophotometrically. The cells were 1 × 10⁻⁶ 5 Cells were cultured in a 96-well plate at a density of cells / mL for 24 hours. Next, R-hth-507 cells were treated with a sample and lysed in MQ. After 24 hours, cell viability was determined using MTT reagent as follows: 10 mL of MTT solution (5 mg / mL PBS) was added to each well, followed by incubation at 37°C in 5% CO2 for 4 hours. The supernatant was discarded, and 40 mM HCl-isopropanol (100 mL) was added to dissolve the formazan crystals. Absorbance was measured at 570 nm using a Microplate Reader 310-Lab (Corona Electric Company, Ibaraki, Japan).
[0059]
[0080] The cytotoxicity test results showed that only one sample (number 7) exhibited a higher cell viability compared to the water control among the 23 samples tested. On the other hand, 13 samples showed cytotoxicity to R-hth-507 cells.
[0060]
[0081] Areca catechu (Sample 7), also known as betel nut, is widely used as chewing tobacco. Chewing betel nut produces mental stimulating effects such as stress reduction, euphoria, and happiness. Our results also support the possibility that betel nut can protect nerve cells that can alter a person's mood. However, such extracts have been reported to increase the risk of oral and pharyngeal cancers from which the plant is chewed (Athukorala et al., J. Addict. 2021; 2021:9967097).
[0061]
[0082] Cell death can occur due to the high concentrations used in each sample. While natural plant extracts can be safe and beneficial to health and well-being, it is important to note that even if a natural plant extract has a positive effect on an individual, it can be harmful to our bodies at different concentrations. Therefore, it is crucial to identify the appropriate amount to obtain the functional effects of natural products while reducing the risk of side effects.
[0062]
[0083] Second screening: Optimizing the concentration
[0084] In the second screening, each sample was prepared at different concentrations as shown in [Table 1]. Samples 6 and 10 showed significantly higher cell viability of R-hth-507 cells than cells treated with MQ in the second screening. The mean cell viability of samples 4, 5, 7, and 9 was slightly higher than that of the water control. This is because the cells used in this study were rat brain hypothalamic neurons, and the high cell viability of these samples against R-hth-507 is consistent with previous studies. In Figure 2, it can be seen that sample 9 (Lignosus rhinosalas) at 10 μg / mL was not cytotoxic to R-hth-507 cells.
[0063]
[0085] [Table 1]
[0064]
[0086] Eight samples showed cytotoxicity to the tested cells, and these samples showed a similar trend in the first screening (sample numbers 11-14 and 17-20). Conversely, based on the results of the second screening of the second sample concentrations, eight samples that showed the highest neuroprotection and no cytotoxicity to R-hth-507 cells (sample numbers 2, 4, 5, 6, 7, 9, 10, and 23) were selected for use in real-time PCR testing. Further experiments were conducted with these better-performing extracts.
[0065]
[0087] Real-time PCR
[0088] The gene expression of proopiomelanocortin (POMC), which is involved in β-endorphin synthesis, was investigated by real-time PCR. Sample concentrations in this experiment [Table 1] were determined based on the first and second screenings. After synthesis in the brain, POMC is broken down into endorphins and corticosteroids by enzymatic action. Therefore, increased POMC gene expression is suggested to increase endorphin production.
[0066]
[0089] Real-time PCR
[0090] R-hth-507 cells were placed in a 100 mm dish at a rate of 0.4 × 10⁶ cells per dish. 5Cells were seeded. After 24 hours of incubation, water-extracted samples or MQ as a control were added to the R-hth-507 cells. The R-hth-507 cells were then cultured for 96 hours. Total RNA was purified from R-hth-507 cells cultured using ISOGENE II (Nippon Gene, Tokyo, Japan). cDNA strands were synthesized from 500 ng of total RNA using ReverTra Ace qPCR RT Master Mix (TOYOBO, Osaka, Japan). Quantitative real-time PCR was performed in a total reaction volume of 25 μL using SYBR Premix Ex Taq II (TaKaRa Bio, Shiga, Japan) and 20 ng of cDNA per reaction. Real-time PCR was performed using a Thermal Cycler Dice Real Time System Lite TP700 (TakaRa, Japan) under the following conditions: 30 seconds at 95°C, followed by 5 seconds at 95°C and 30 seconds at 60°C, each for 40 cycles. The primers used for amplification were as follows: CCTCACCACGGAAAGCA and TCAAGGGCTGTTCATCTCC for POMC, and TTGTGCAGTGCCAGCCTC and CCAATACGGCCAAATCCG for GAPDH.
[0067]
[0091] As a result, POMC gene expression was confirmed to increase with the addition of most of the tested plant extracts compared to the control, with the exception of sample 2. Samples 5 and 7 showed more than three times the POMC gene expression of water-treated cells, and sample 9 (Lignosus rhinosaras) induced more than two times the expression of POMC genes, as can be seen in Figures 3A and 3B. Each of these results suggests that such substances or extracts may induce euphoric feelings in individuals who ingest them. A water extract of Centella asiatica, a plant similar to sample 5, has previously been found to have cognitive-enhancing effects in animal models of aging and Alzheimer's disease. The mechanism of Centella asiatica's cognitive-enhancing effect is hypothesized to involve the upregulation of nicotinamide adenine dinucleotide and the regulation of brain-derived neurotrophic factor in the brain (Speers et al., Front Pharmacol. 2021;12:788312). The cells used in the current study are nerve cells, and the regulation of neurotrophic factors can affect R-hth-507 cells. C. pluricaulis, a plant similar to sample 4, has been previously reported to have antidepressant-like effects on neuroinflammation-associated depressive behavior induced by chronic, unpredictable mild stress in rats (Gupta & Fernandes Biomed Pharmacother. 2019; 109: pp. 1698-1708). The current results also support the possibility that samples 4, 5, and 9 possess neuroprotective systems that promote calmness and reduce stress and anger.
[0068]
[0092] Sample 9 (Lignosus rhinosaras), commonly known as tiger milk mushroom, also exhibited high POMC gene expression activity. L. rhinosaras possesses functional activities such as antioxidant, immunomodulatory, and skin conditioning effects (Kittimonkolsuk et al., Pharmaceuticals 27;14(2):93 2021). To our knowledge, this is the first report that L. rhinosaras may have an impact on mental health. Samples 23 and 10 activated POMC genes approximately twice as much as the control. POMC gene expression activity of sample 10 was observed at 10 μg / mL, a concentration far below the reported toxic concentration; therefore, if an aqueous extract of sample 10 is to be used as a medicine or dietary supplement, it must be at a low and safe concentration.
[0069]
[0093] Endorphins are neurotransmitters that function in the brain and are thought to be involved in the endogenous analgesic system, producing feelings of euphoria. The seven plant extracts tested were able to increase POMC production, which may produce varying degrees of euphoria.
[0070]
[0094] Cells are selected based on their ability to produce certain hormones related to mood, such as: The cell line SH-SY5Y may be associated with the gene expression of arylalkylamine N-acetyltransferases, which are involved in melatonin and sleep. The Neuro2A cell line may be associated with the gene expression of serotonin / melatonin and tryptophan hydroxylase, which is involved in healing or happiness. The cell line R-HTH 507 may be associated with the gene expression of β-endorphin and the β-endorphin POMC gene, which is involved in euphoria; The cell line PC12 may be associated with the gene expression of dopamine, NE or epinephrine, and tyrosine hydroxylase, which is involved in pleasure; and The cell line CNI-H295R may be associated with the gene expression of cortisol and cortisol 11-beta-hydroxysteroid dehydrogenase.
[0071]
[0095] The initial aqueous extracts of Labisia pumila and Lignosus rhinosalas were prepared and tested in the aforementioned cells, and the expression of genes involved in cell activation and hormone production was identified, based on this screening step.
[0072]
[0096] Further studies in the PC12 cell line demonstrated that extracts of either the Lavisia pumila plant or the Lignosus rhinosala fungus, dissolved in ethanol, both exhibited positive cell activity activation. Lignosus rhinosala extracts at concentrations of 50 μg / mL and 100 μg / mL in 50% ethanol improved PC-12 cell viability by 147% and 139%, respectively. Similarly, Lavisia pumila extract at 50 μg / mL improved PC-12 cell viability by 143%.
[0073]
[0097] Example 2 Functional evaluation tests targeting genes and enzymes related to mental function.
[0098] Hot water extracts were prepared from two promising plant samples (i.e., Sample 13 and Sample 9). Sample 1 was newly named as it was an extract from Lignosus rhinosalas. Sample 2 was an extract from Labisia pumila. These samples were stored in a 20 mg / mL DMSO solution.
[0074]
[0099] Functional evaluation tests [Table 2] were performed on two extract samples prepared as described above, targeting genes and enzymes related to mental state-related functionality. The compounds were tested at 20.0 μg / ml.
[0075] [Table 2]
[0076]
[0100] Compound binding was calculated as the percentage inhibition of binding to the radiolabeled ligand specific to each target. Compound enzyme inhibitory effect was calculated as the percentage inhibition of control enzyme activity. Cellular agonist effect was calculated as the percentage of the control response to a known reference agonist for each target, and cellular antagonist effect was calculated as the percentage inhibition of the control reference agonist response to each target. Results showing inhibition or stimulation higher than 50% were considered to represent a significant effect of the test compound sample, while samples with 30% to 50% activity were considered "probably active."
[0077]
[0101] The results of the functional evaluation study revealed that the extract exhibited activity at six different receptors targeting cannabinoid receptor 1, dopamine D2 receptor, μ (mu) opioid receptor, δ (delta) opioid receptor, cyclooxygenase, and GABAA receptor. In six studies targeting cannabinoid receptor 1, dopamine D2 receptor, GABAA receptor, μ opioid receptor, delta opioid receptor, and cyclooxygenase, both samples (Lignosus rhinosaras and Labisia pumila) showed activity.
[0078]
[0102] In vitro pharmacology: Cellular and nuclear receptor function assays. Agonist effects: Results of test compounds.
[0079]
[0103] Agonist activity against the human opioid receptor mu-1 (mu(MOP)(h)) was observed in extracts from Lignosus rhinosalas (23%) and Labisia pumila (13%). The expected function of these materials is euphoria.
[0080]
[0104] In vitro pharmacology: Enzyme and uptake assays
[0105] Inhibitory activity against human cyclooxygenase (COX1(h)) was found in Labisia pumila extract at 55.9%. Potential activity was observed in Lignosus rhinosalas (40.2%). The expected functionality of these materials is euphoria or well-being. Inhibition of the Cox1 pathway is also known to reduce inflammation and, therefore, lower body temperature and alleviate pain, and is an established mechanism for drugs such as aspirin and ibuprofen, as well as other pharmaceuticals. While speculation on how a reduction in body temperature or pain can deliver euphoria is still uncertain, it is thought that such a reduction in inflammation could reduce systemic stress, and therefore, anti-stress, relaxation, and calming effects can be explored.
[0081]
[0106] Example 3: Gene expression analysis of cells
[0107] Increased expression of three genes was observed in cells exposed to Lignosus rhinosalas extract: APH1B (aph1 homolog B) and the gamma-secretase subunit, one of the subunits of gamma-secretase, an enzyme that produces amyloid-beta, a cause of dementia. Gamma-secretase, an enzyme that produces amyloid-beta, was downregulated by the plant extract.
[0082]
[0108] OPTN optineurin is one of the autophagy functions involved in cellular quality control and is responsible for the normal functioning of cells. OPTN optineurin also plays a role in maintaining normal cellular function. Abnormalities in this gene can cause neurodegeneration. It is expected that increased expression of this gene will suppress cell deterioration. However, the current state of this gene is unclear. Currently, there is no data regarding the suppression of cell deterioration by increasing the expression of this gene.
[0083]
[0109] VGF is known to play a role in neuroprotection by activating cell survival signals. VGF has been shown to promote nerve survival and dendritic growth, protect against retinal nerve damage, repair and grow hippocampal neurons, and act as an antidepressant.
[0084]
[0110] This gene has been shown to promote nerve survival and dendritic growth, protect against retinal nerve damage, repair and grow hippocampal neurons, and exhibit antidepressant effects.
[0085]
[0111] Furthermore, the overall results of the evaluation of the Lignosus rhinosalas extract include gene expression patterns in neuronal cells treated with the plant extract, as shown in [Table 3]. SH-SY5Y cells were treated with a concentration of 10 mg / ml Lignosus rhinosalas extract, and RNA was harvested after overnight incubation. Treatment with Lignosus rhinosalas extract showed a decrease in gene expression of Aph1B, one of the enzymes that produce proteins that cause Alzheimer's disease. Optinulin was an upregulated gene in Lignosus rhinosalas extract-treated samples, and is involved in the autophagy process, suggesting that its extract may maintain cell health. In addition, VGF was also upregulated in Lignosus rhinosalas extract-treated samples. VGF is a gene that induces nerve growth and activates dendritic survival signals, suggesting its role in neuroprotection overall [Table 3]. In summary, based on its use in neuronal cell types such as SH-SY5Y, Lignosus rhinosalus extract can protect nerve cells, induce their growth, and activate genes that maintain nerve cell health.
[0086] [Table 3]
[0087]
[0112] Based on the in vitro results, two plant extracts, an extract from Lignosus rhinosaras and an extract from Labisia pumila, were selected for further detailed analysis and characterization.
[0088]
[0113] Example 4: Extraction process and characterization of Labisia pumila
[0114] The leaves and / or stems of Labisia pumila were prepared as outlined in [Figure 4]. First, the raw material leaves or leaves and stems are collected [Step 1]. Next, these raw materials are dried in an oven at 35-50°C for 2-4 days. Alternatively, these raw materials may be freeze-dried or vacuum freeze-dried. After drying, the stems and leaves are ground to a powder, and the powder (100-200 kg) is then fortified by dissolving the powder in water (500-1000 L) at a temperature of 70-90°C for several hours with constant stirring [Step 2]. The fortification step may be repeated, and filtration [Step 3] may be performed after the fortification step(s) and / or between these fortifications if it is repeated. Next, the fortified liquid is concentrated or evaporated by any known conventional means [Step 4]. The concentrate is pasteurized at a temperature of 70-90°C [Step 5], then filtered [Step 6], followed by spray drying [Step 7], and separated using a metal separator [Step 8], leaving a purified extract powder. The purified extract is a brown powder containing 0.1-0.2% gallic acid.
[0089]
[0115] Characterization of Labisia pumila plant extract
[0116] Prior to characterizing the purified Labisia pumila extract by HPLC, the extract was dissolved in a solvent (water) in a weight ratio of 4:1 (water to extract) or 5000 μl of 10 mg / ml was injected into a 1290LC01 HPLC in a 50% pure methanol to water solvent ratio. As seen in [Figure 5], a peak conforming to the gallic acid reference standard was observed at a retention time of 4.301 minutes, which was calculated from the standard reference to be approximately 0.191% of the extract composition, and an unidentified peak was observed at a retention time of 9.978 minutes, with a first series of smaller unidentified peaks observed at retention times of 1–2 minutes, and a second series of even smaller unidentified peaks observed at retention times of 10–13.5 minutes.
[0090]
[0117] Example 5: Extraction process and characterization of Lignosus rhinosaras
[0118] Lignosus rhinosalas is a polyporous or fungal species with large fruiting bodies that have pores or tubes on the underside. Only Lignosus rhinosalas with a pore size of 6-7 pores / mm were selected. Selection can also be made based on the unique nucleotide sequence of the internal transcription spacer (ITS) ITS1 region (bases 149-168) located between the rRNA structural genes, which is listed here as Sequence ID No. 1, using PCR primers (5'-GTTTTCAGCCGGCGTTTGC-3') and (5'-TCCTCCGCTTATTGATATGC-3'). Using subterranean sclerotia, extracts were prepared according to the procedure in [Step 1] [Figure 4], in which subterranean sclerotia are first collected. These sclerotia were then dried in an oven at 35-50°C for 2-4 days, or alternatively, these sclerotia may be freeze-dried or vacuum freeze-dried. The stems and leaves are dried and then ground into a powder (100-200 kg), which can then be fortified by dissolving the powder in water (500-1000 L) at a temperature of 70-90°C for several hours with constant stirring [Step 2]. The fortification step may be omitted in some cases, and filtration [Step 3] may be performed after the fortification step or immediately after the grinding step or extraction. The filtered product is then concentrated or evaporated by any known conventional means [Step 4]. The concentrated product is pasteurized at a temperature of 70-90°C [Step 5], then filtered [Step 6], then spray-dried [Step 7], separated using a metal separator [Step 8], leaving a purified extract powder. The purified extract is a fine, light brown powder.
[0091]
[0119] Lignosus rhinosalas extract was analyzed and found to contain 1% fat, 28-30% carbohydrates, 28% protein (of which over 10% is glycoprotein), 2% calcium, 4% potassium, and 35% magnesium.
[0092]
[0120] Example 6: In vivo study in mice
[0121] A study design for a preliminary evaluation of the relaxation / sedation, invigorating, and happiness / euphoria effects of eight extract samples at two different doses in mice. The animal studies were designed to gradually expose animals to increasingly stressful studies, minimizing potential interactions between studies. This ensured that stress levels from previous studies would not affect subsequent studies. The study schedule is outlined in [Table 4].
[0093] [Table 4]
[0094]
[0122] Behavioral assessments of relaxation / sedation, invigoration, and well-being effects were conducted. In each behavioral test, control mice fed a standard laboratory animal solid diet were randomly included in a series of animals tested for comparison with mice fed an extract-supplemented diet. The application of the extract incorporated into the diet was designed so that the uptake by each animal was expected to be 0.25% and 0.5% of the diet composition. On average, one animal consumed 3–5 g of diet per day, and therefore, each animal was expected to consume approximately 10 mg (0.25%)–20 mg (0.50%) daily.
[0095]
[0123] Each study consists of three groups: 1) a control group, 2) a 0.25% diet group, and 3) a 0.50% diet group. Each group contains 10 mice.
[0096]
[0124] Food pellet preparation
[0125] Plant extract samples were custom-formulated into standard mouse solid feed pellets for oral administration in the diet. Mice were freely given the custom-formulated diet. Control animals were freely given the same standard diet without any extracts. All diets were gamma-irradiated to ensure sterility.
[0097]
[0126] To test the acute effects of dietary consumption of the extracted substance, mice were fed a custom-formulated diet daily from the day before the test until the end of the test. Since most mice eat at night, the delivery of the custom-formulated diet containing the extracted substance from the day before the test ensured that the mice received their diet overnight. Following this schedule, each group of mice needed to be fed the custom-formulated diet for 10 days.
[0098]
[0127] On average, mice consume 3g to 5g of experimental food per day. However, some food is lost during feeding and gnawing (approximately 10% loss), and pellets remain uneaten in the hopper (approximately 20% loss). Therefore, each group of 10 animals fed for 10 days used at least 660g of food, taking into account maximum food consumption and potential losses.
[0099]
[0128] The limiting factor for the amount of each plant extract required is the production scale of the custom-formulated feed. The formulation, mixing, and pelletizing processes are limited by the scale of the equipment used by the feed manufacturer. Therefore, the minimum amount that can actually be custom-formulated is approximately 2.65 kg, yielding approximately 1.9 kg to 2 kg per batch.
[0100]
[0129] Therefore, 20g of each plant extract was required to obtain approximately 2kg of 0.25% custom-formulated diet and approximately 2kg of 0.5% custom-formulated diet.
[0101]
[0130] The following are plant extracts: • Lavisia pumila 0.25%; • Lavisia pumila 0.5% • Lignosus rhinosaras 0.25%; and • Lignosus rhinosaras 0.5% Includes.
[0102]
[0131] Behavioral evaluation in mice
[0132] Behavioral assessments of relaxation / sedation, invigoration, and happiness / euphoria effects will be conducted. In each behavioral test, control mice fed a standard laboratory animal solid diet will be randomly included in a series of animals tested for comparison with mice fed a diet supplemented with plant extract samples.
[0103]
[0133] Relaxation / Sedation
[0134] Relaxation and sedation effects were assessed through a standard behavioral paradigm to detect anxiety and anxiolytic-like effects. These tests were the light-dark box paradigm [Figure 6A] and the elevated zero maze [Figure 6B]. The elevated zero maze is an improved version of the conventional elevated cruciform maze that overcomes the problem of an uncertain central zone in the cruciform maze.
[0104]
[0135] Light and dark box
[0136] Mice were tested in chambers with light and dark zones. Animals were individually positioned in the center of the light arena. The duration of time spent in the light and dark arenas and the number of times they passed between the two arenas were recorded. Sensors on the doors between the light and dark arenas allowed for unbiased measurement of time spent in each arena and the number of times they passed between them. Mice have an innate motivation to explore as wide as possible to find potential food sources. However, this motivation to explore in the light chamber conflicts with the mouse's natural behavioral response of preferring dark areas to light areas to avoid being discovered by potential predators. Therefore, the increased time spent exploring in the light chamber becomes a measure of relaxation or sedation.
[0105]
[0137] In the light-dark box test, anxiety levels are assessed by the amount of time spent in the light box. If the test group spends longer in the light box than the control group, the animals in the test group are considered to have reduced anxiety-like behavior. Conversely, if the time spent in the light box is shorter than that spent in the control group, it suggests that anxiety-like behavior is increased. From [Figure 7A], mice in the 0.5% groups of both Labisia pumila and Lignosus rhinosaras spent more time in the light box than the control group mice, suggesting that these two plant extract diets may have an anxiolytic effect, although this is not statistically significant.

[0138] Elevated Zero Maze
[0139] Mice are individually allowed to freely explore a zero-type maze consisting of open areas and enclosed areas surrounded by side walls. The maze is elevated approximately 50 cm. Subjects are allowed to explore the maze for 5 minutes. The number of times they pass between the open and enclosed areas, the waiting time to enter the open area, the amount of time spent in the open area, and the number of times they enter it are recorded. A computer video tracking system using near-infrared illumination, which allows tracking of the mice even in the enclosed areas, is used for unbiased recording of their behavior. Mice have an innate motivation to explore, but this is in the open area of the zero-type maze, which conflicts with exposure to potential predators and an innate fear of the maze's elevated height. Therefore, an increase in the time spent exploring the open area is a measure of relaxation or sedation.
[0107]
[0140] In the zero maze, anxiety levels are assessed by the amount of time spent in the open arm. Longer periods of time spent indicate a reduction in anxiety-like behavior. While there was no significant difference between the extract diet group and the control diet group, both the 0.5% groups of Labisia pumila and Lignosus rhinosaras showed a longer average time spent in the open arm than the control group.
[0108]
[0141] Cheer up
[0142] The mental function-enhancing effect was assessed through the measurement of spontaneous exploratory behavior in a dark, open field [Figure 8A] and through the measurement of spontaneous working memory alternation behavior in a Y-shaped maze [Figure 8B]. These behavioral paradigms utilize the normal behavior of mice to measure mental activation.
[0109]
[0143] Exploring open fields in the dark
[0144] Mice were individually placed in an open-field arena in darkness (less than 20 lux) illuminated only by red / near-infrared light. Mouse movements were tracked using a computer video tracking system employing a near-infrared sensing camera. Because mice have limited vision for red light, the room appeared dark from their perspective, and they were not inhibited from exploring the open field by their innate fear of exposure to bright light. Under these conditions, the open-field paradigm measures spontaneous exploratory behavior. Increased exploratory behavior indicates mental activation.
[0110]
[0145] A dark, open field measures spontaneous exploratory behavior. Increased exploratory behavior indicates mental activation. Among the groups fed a plant extract diet, mice fed a 0.5% Labisia pumila extract diet showed increased exploration in a dark, open field compared to the control group [Figure 9A].
[0111]
[0146] Spontaneous alternating work memory
[0147] Mice are individually positioned in the center of a Y-shaped maze with three arms at 120° angles to each other. The animals are allowed to freely explore all three arms. The animals are tracked using a computer video tracking system. If a mouse possesses intact spatial working memory, it is less likely to enter the most recently visited arm. The number of arm entries is scored to determine the number of alternations. A mouse is considered to have entered an arm if all four limbs are within that arm. An increase in spontaneous alternation behavior indicates mental activation.
[0112]
[0148] In the spontaneous alternation working memory test, animals freely explore all three arms of a Y-shaped maze. If a mouse has intact spatial working memory, it will have a reduced tendency to enter the most recently visited arm. Arm entries are scored to determine the number of alternations. Increased spontaneous alternation behavior indicates mental activation. Results of spontaneous alternation in the Y-maze compared to a control as an indicator of working memory [Figure 9B].
[0113]
[0149] Happiness / Euphoria
[0150] Euphoria and euphoric effects were measured using a dietary preference test [Figure 10C] and two conventional paradigms used to detect antidepressant-like activity. The two paradigms for testing antidepressant-like effects are the tail suspension test [Figure 10A] and the forced swim test [Figure 10B]. The two tests are performed because they have different sensitivities. The tail suspension test yields clearer results with less individual variability between mice, but has lower sensitivity. Therefore, it is also helpful to include the forced swim test, which has better sensitivity.
[0114]
[0151] Feeding palatability
[0152] Mice are presented with conventional laboratory animal solid feed individually, while diets containing herbaceous samples are placed separately in two small ceramic cups located at opposite ends of their home cage. The amount of food consumed is weighed. The longer the time spent eating from the cups containing the supplemented diet, the greater the pleasure or well-being effect of the diet.
[0115]
[0153] In the dietary preference test, mice were individually presented with conventional laboratory animal solid feed, while diets containing herbaceous samples were placed separately in two small ceramic cups located at opposite ends of their home cages. The amount of food consumed was weighed. The longer the time spent eating from the cups containing the supplemented diet, the greater the pleasure or well-being effect of the diet. Among the herbaceous diet groups, mice fed with Lignosus rhinosaras extract showed the same preference for both the herbaceous diet and the control diet [Figure 11A]. In contrast, mice fed with Labisia pumila extract preferred the control diet to the plant extract diet.
[0116]
[0154] Compulsory swimming test
[0155] Mice are individually placed in cylinders filled with water. Their movements are monitored. Immobility is considered to mimic a state of emotional depression. An increase in the time it takes to become immobile indicates an antidepressant-like euphoric effect.
[0117]
[0156] In the compulsory swimming test, a reduction in immobility time compared to the control group indicates an antidepressant-like euphoric effect. In the extract diet group, little difference was observed compared to the control group, suggesting that these extracts may not have an antidepressant-like euphoric effect [Figure 11B].
[0118]
[0157] Tail suspension test
[0158] Mice are suspended by their tails for six minutes. Movement is monitored, and a decrease in movement is considered to mimic emotional depression. The animals are suspended at a fixed distance from the base of their tails on a standard behavioral apparatus widely used for behavioral testing, so there is no risk of tail injury or slippage. An increasing time until the animal becomes still indicates an antidepressant-like euphoric effect.
[0119]
[0159] In the tail suspension test, a reduction in the length of time spent motionless compared to the control group indicates an antidepressant-like well-being effect. There were no significant differences between the groups in the tail suspension test [Figure 11C].
[0120]
[0160] Example 7: Measurement of hormones and neurotransmitters
[0161] At the end of the in vivo experiment, brain tissue and plasma derived from core blood samples were assayed for corticosterone, dopamine, and 5-HT (serotonin) [Figure 12]. The assays were performed using ELISA kits. Each ELISA kit can be run in a 96-well plate. In each plate, samples from mice fed a control diet were run alongside samples from mice fed a herbaceous supplement diet.
[0121]
[0162] Brain tissue was homogenized according to the instructions provided with the Enzo Lifesciences kit. Mice consuming 0.25% and 0.5% Labisia pumila had significantly lower tissue dopamine levels compared to the control group [Figure 13]. Mice consuming 0.5% Lignosus rhinosala had higher tissue dopamine levels compared to the control. Mice consuming 0.25% Lignosus rhinosala had significantly higher tissue dopamine levels than the control.
[0122]
[0163] Whole blood was collected when the mice were euthanized and the serum was centrifuged to isolate it. The serum samples were then run through the Biovision Serotonin Kit. Serotonin levels were not significantly different in any group compared to the control [Figure 14].
[0123]
[0164] Whole blood was collected when the mice were euthanized and the serum was centrifuged to isolate it. The serum samples were then run through the Enzo Lifesciences corticosterone kit with some modifications to the protocol. The serum samples were incubated with the steroid replacement hormone before being added to the wells. Standards and serum samples were incubated in the wells for 1 hour before the addition of conjugates and antibodies.
[0124]
[0165] The 0.5% Lignosus rhinosalas group showed higher corticosterone levels than the control group [Figure 15].
[0125] [Table 5]
[0126]
[0166] Here, we observed that the Labisia pumila group showed decreased activity in a light box and increased activity in a dark open field, indicating an increase in anxiety-like behavior. Biochemically, this group showed a significant decrease in dopamine levels in brain tissue compared to the control group, and serum levels of serotonin and corticosterone appeared to be decreased, which may underlie the observed anxiety-inducing effect.
[0127]
[0167] In vivo, brain tissue from mice fed a 0.5% Lignosus rhinosarasu diet showed higher dopamine levels compared to controls [Figure 13]. The results suggest that these mice may have experienced feelings of happiness or euphoria. In vivo, serum samples from mice fed a 0.5% Lignosus rhinosarasu diet showed higher corticosterone levels than controls (Figure 15). Higher corticosterone levels are thought to be associated with stress. The results suggest that these mice may have been excited. Here, the behavioral changes in the Lignosus rhinosarasu diet group were not statistically significant. However, dopamine levels were increased in brain tissue, and serum serotonin and corticosterone levels were elevated.
