Abstract
Description
Technical Field
[0001] The present invention relates to a pharmaceutical combination for preventing or treating hair loss, and more particularly, to a pharmaceutical composition for preventing or treating hair loss comprising bacteria of the genus Akkermansia as an effective ingredient, a food composition for preventing or improving hair loss or for promoting hair growth, and a cosmetic composition. Background Art
[0002] With the progress of modern society, the number of patients suffering from hair loss has increased dramatically, and the age of patients suffering from hair loss has become younger and younger. Among people in their twenties and thirties, the number of patients suffering from hair loss has increased sharply.
[0003] It is reported that as hair loss worsens, psychological symptoms of depression or tension become increasingly prominent, sensitivity to stress also becomes increasingly severe, it is difficult to adapt to interpersonal relationships or relationships with the opposite sex, and it also brings flaws to family life, becoming a major concern in health care.
[0004] The cause of hair loss is still unknown, but possible causes reported include genetic factors, hormonal abnormalities, and immunological abnormalities.
[0005] Androgenic alopecia (AGA) is hair loss caused by the action of androgens on androgen-sensitive hair follicles, which results in vellus hair. It is speculated that this is largely related to genetic factors. Estrogenic alopecia is believed to be caused by a decrease in the amount of estrogen relative to androgen in the bloodstream. Most cases occur after menopause, and estrogenic alopecia can be improved through hormone replacement therapy, but it is still a difficult disease in most cases.
[0006] Drugs that can be used in the treatment of androgenic alopecia include androgen activity inhibitors such as minoxidil and finasteride, female hormones such as estrogen, estradiol, and progesterone, ketoconazole as an antifungal agent, pentadecane, cytopurine (6-benzylaminopurine), tertiary flavanone, adenosine, and the like.
[0007] However, minoxidil has side effects such as drug-induced hair loss, excessive hair growth, lowered blood pressure, and decreased heart rate, and has the problem of recurrence immediately after stopping use. On the other hand, finasteride has side effects such as prostate hyperplasia, erectile dysfunction, and ejaculation disorders, and has the side effect of worsening symptoms after stopping use. In addition, if women use minoxidil in high doses, it will cause hirsutism or the risk of giving birth to deformed babies. Finasteride has the risk of giving birth to deformed babies, so women, especially pregnant women, are prohibited from taking it.
[0008] In addition, there are many products that contain ingredients that promote blood circulation, strengthen hair root function, moisturize the scalp, remove dandruff, have anti-oxidation effects, and extend the hair growth period as active ingredients. However, these existing preparations have not yet proven to have outstanding therapeutic effects in terms of effects, and instead have raised the problem of side effects.
[0009] On the other hand, as an effort to use microorganisms to obtain anti-hair loss effects, Korean Patent No. 1600012 discloses a hair loss treatment agent that uses microorganisms such as Lactobacillus plantarum to ferment wild rice stem and malt, and then adds raw materials such as Houttuynia cordata and Polygonum multiflorum to it. Korean Patent Publication No. 2022-0021144 discloses a pharmaceutical composition for treating prostatic hyperplasia or alopecia that contains lactic acid bacteria of the genus Enterococcus as an active ingredient. However, these compositions have not yet shown significant hair loss treatment effects. Summary of the invention

[0070] Example
[0071] Example 1
[0072] 1.1. Bacterial strain samples
[0073] The live Akkermansia muciniphila EB-AMDK19 (KCTC 13761BP) used in this experiment was 1×10 8 The concentration of CFU / 100 μL PBS (25% glycerol, 0.05% cysteine / PBS) was prepared.
[0074] Animal experiments
[0075] Animal experiments were conducted in accordance with the Animal Use and Care Protocol of the Institutional Animal Care and Use Committee (IACUC). Seven-week-old male C57BL / 6 mice were purchased and acclimated for one week before being raised for 5 weeks. The breeding environment maintained a specified temperature (22°C) and relative humidity (40% to 60%), and the light and dark were adjusted in a 12-hour cycle. A normal diet (chow diet) was provided to all experimental groups.
[0076] 1.3. Sample administration and experimental group setting
[0077] As shown in Table 1 below, the mice were divided into 4 groups (8 mice / group), and each mouse was subcutaneously injected and orally administered with each drug five times a week for a total of five weeks. In order to prepare a hair loss model, 0.5 mg / day of testosterone was subcutaneously injected into mice in all experimental groups. The group induced with hair loss by administration of testosterone was used as a negative control group, and the positive control group was orally administered with 0.5 mg / kg / day of finasteride. PBS containing L-cysteine and glycerol was orally administered as a solvent in the live and dead bacteria administration groups of the genus Akkermansia of the present invention.
[0078] [Table 1]
[0079]
[0080] Test Example 1: Photo confirmation experiment of hair growth in mice
[0081] For the mice in each experimental group, the extent of hair growth was observed by taking photos of the hair. Figure 1The photos show the hair growth and regrowth over the number of days the sample was applied to the hair loss-induced mice. From the left, the results are the negative control group (testosterone), the positive control group (T+finasteride), the group administered with live Akkermansia muciniphila (T+EB-AMDK19), and the group administered with dead Akkermansia muciniphila (T+EB-AMDK19 HI). Each group applied 100 μL daily for 5 weeks, and confirmed whether hair growth occurred in the hairless area on the back of the mouse.
[0082] pass Figure 1 It was confirmed that the skin color of the finasteride-treated group, which served as the positive control group, darkened from the third week of treatment, and the growth of hair shafts was as expected. As time passed, the range gradually expanded, and in the fifth week, almost all parts turned black.
[0083] In the negative control group (testosterone), until the fifth week when the observation was completed, the skin color remained pink and almost all parts were free of hair.
[0084] In mice to which the sample containing live Akkermansia muciniphila was applied, a dark blue skin color was observed on the tail side of the hair loss site one week after the application, indicating that the expected result of hair growth was achieved faster than in the case of the positive control group. As a result, hair growth was significantly observed in the lower half of the hair loss site from the third week of application.
[0085] On the other hand, in the case of mice to which the dead bacterial cell sample of Akkermansia muciniphila was applied, similar to the live bacteria administration group, a dark blue skin color was observed in the central part of the area where hair loss occurred one week after the application, and from the fourth week of the application, hair growth began to occur significantly in the lower part of the area where hair loss occurred.
[0086] Test Example 2: Hair growth length increasing effect
[0087] After the 5-week experiment, the hair length of each individual in each experimental group was measured and the average value was calculated. Figure 2a , Figure 2b The graph shows the results of a hair growth length increase experiment.
[0088] Reference Figure 2a-2b First, it can be seen that the hair length of the negative control group to which distilled water was applied did not undergo a sudden growth or other changes.
[0089] The hair lengths of the finasteride-administered group and the live Akkermansia-administered group (T-EB-AMDK19), which served as the positive control group (T+finasteride), were similar. In contrast, the hair length of the group administered with dead Akkermansia cells (T+EB-AMDK19HI) was relatively short.
[0090] Results, such as Figure 2a-2bAs shown, it was confirmed that the hair length significantly increased with the treatment of Akkermansia strains, regardless of whether the treated cells were live or dead bacteria, compared with the control group (Control).
[0091] Test Example 3: Measurement of body weight and tissue weight
[0092] After the 5-week experiment, the mice in each group were euthanized, and the liver and prostate tissues were removed and weighed. Figure 3a-3c Take a picture of the prostate and compare (refer to Figure 4 ).
[0093] There was no change in body weight among the groups of mice, nor was there a significant difference in liver or prostate weight. There was also no significant change in prostate size.
[0094] Test Example 4: Experiment on the measurement of histological changes of mouse hair follicles
[0095] In order to confirm the morphological changes of hair follicles in male C57BL / 6 mice, the skin tissues collected in the fifth week of transdermal administration were stained with hematoxylin and eosin and the number of hair follicles was observed under a microscope. Figure 5a and Figure 5b shown.
[0096] Results of measuring the number of telogen hair follicles following sample treatment in C57BL / 6 mice induced with alopecia, as shown in Figure 5a-Figure 5b As shown, in the case of finasteride treatment, it was confirmed that the number of hair follicles in the telogen phase increased compared to the negative control group.
[0097] In contrast, when the Akkermansia strain (live bacteria) of the present invention was administered, it was confirmed that the number of hair follicles in the telogen phase increased significantly compared to the negative control group. In particular, when the Akkermansia strain (dead bacteria) of the present invention was administered, it was confirmed that the number of hair follicles in the telogen phase increased significantly.
[0098] The above description is only an example of the technical concept of the present invention.
