85 results about "Depression model" patented technology

While a number of other models for depression exist, including genetic models, olfactory bulbectomy, and early maternal deprivation, stress-induced depression models are some of the most widely used. They exhibit strong face validity, sharing many phenotypic outcomes with depression.

Chinese medicinal composition for treating tristimania

ActiveCN101816766AElevated monoamine neurotransmittersSoothe the liver and relieve stagnationNervous disorderPlant ingredientsAcute toxicity testingHard Capsule
The invention discloses a Chinese medicinal composition for treating tristimania, which is prepared into certain formulations by taking curcuma longa, St John's wort and ginseng as raw materials, and extracting and separating the raw materials by using 0-75 percent ethanol. An animal toxicity test result shows that 284 times of an adult dosage of the medicinal composition for lavaging a mouse causes no acute toxicity reactions; a pharmacodynamic study shows that the medicinal composition can significantly perform antagonism on acinesia and hypothermia, induced by reserpoid, of a tristimania model mouse, and can increase the number of autonomic activities and the dead time for tail suspension and swimming, induced by the tail suspension and forced swimming, of a desperate animal model. A clinical research result shows that by adopting a Hamilton rating scale for depression (HAMD) to evaluate the depression severity which serves as the primary therapeutic effect index, a treatment group obtains a significant curative effect, the effective rate is 92.3 percent, and compared with a control group, the medicinal composition has significant differences but has no toxic and side effects. The medicinal composition can be prepared into medically acceptable oral preparations, such as tablets, capsules (soft capsules or hard capsules), granules and the like; and the clinical curative effect and the pharmacodynamic study prove that the medicinal composition has the functions of smoothing the liver to alleviate mental depression and relieving mental stresses, and is an effective special medicament for treating the tristimania.

Study method using capillary electrophoresis and UPLC-MS (ultra performance liquid chromatography - mass spectrometry) to analyze regulating function of PQQ (pyrroloquinoline quinone) on catecholamine neurotransmitter

The invention relates to a study method using capillary electrophoresis and UPLC-MS (ultra performance liquid chromatography - mass spectrometry) to analyze a regulating function of PQQ (pyrroloquinoline quinone) on catecholamine neurotransmitter, and belongs to the technical field of biological analysis. The method comprises the following steps of extracting brain tissues by anion solid-phase extraction, measuring the change of content of catecholamine in a mouse brain of a chronic stress induced depression model and the change of a reaction product of catecholamine, well separating PQQ, NE (noradrenaline), E (epinephrine) and products, and using UPLC-MS to identify the PQQ and the catecholamine reaction product. After proofing by results, the PQQ reacts with NE to generate the PQQNE, but does not react with E. The method has the advantages that the contents of NE in frontal lobe and hippocampus of the chronic stress induced depression model are obviously increased; by applying a certain amount of PQQ group, the content of NE is obviously decreased, and the contents of E in different groups are not obviously different; the PQQ is mainly used for regulating the catecholamine neurotransmitter through regulating the NE, but has no regulating function on E; the guidance meaning on the study of the depression disease mechanism and depression targeted medicine is realized.
