3. the mechanism of action
3.1 granule of the present invention is to the influence of adult mice brain protein content and brain monoamine oxidase (MAO)
[purpose] inquired into granule maybe the mechanism of action.
[principle] cerebral cortex is the material base of learning and Memory, and in the process of learning and memory, the synthetic increase of brain internal protein stores through the experience that new synthetic protein will newly obtain.Brain protein SYNUCLEINS and nucleotide level are brain aging degree and the strong and weak material base of learning and memory; MAO is the enzyme of catalyze aromatic, aliphatic monoamine oxidative deamination radical reaction widely, is divided into A, B amphitypy, and it is with old and feeble closely related.Most results of study show that human brain MAO-B is active relevant with the age, and promptly its activity sharply increased with age growth after 45 years old.That is to say the aging along with body, brain MAO-B is active constantly to rise.Along with the active continuous rising of MAO-B; The brain monoamine can neural regulating action descend day by day; Cause the imbalance that neuroendocrine is regulated; The symptom of degeneration central nervous system disease such as Parkinson's disease appears in the degeneration, the abnormal behavior that not only cause the brain physiological function, but also causes that whole machine body is progressively old and feeble.
48 of [method] 12 monthly age kunming mices, male and female half and half, body weight 50 ± 5g is divided into 4 groups at random, 12 every group: the blank group, the granule high dose, in, low dose group.The administration capacity: every treated animal is pressed 0.2ml/10g, the ig administration.Blank control group gives equal-volume physiological saline; The administration group gives respectively: high dose group 8.30gkg-1d-1, middle dosage 3.34gkg-1d-1, low dosage 1.66gkg-1d-1 (more than be the crude drug amount); Successive administration 30d; Behind the last administration 1h; All disconnected neck is put to death animal, gets the full brain of mouse on the ice pan fast, is used for the mensuration of MAO activity and brain tissue protein content.(the active mensuration of MAO-B is undertaken by the kit explanation; The brain tissue protein content determination is explained by kit (Coomassie brilliant blue method) and is carried out
[result] is visible by table 3, and high, medium and low dose groups of particle and blank control group comparison brain protein content and activity of monoamine oxidase difference have conspicuousness (the P value is all less than 0.05).Can think has the rising effect to aged mouse brain tissue protein content, and monoamine oxidase in the brain (MAO-B) activity is had the reduction effect.(the P value is all greater than 0.05).
Table 3 is respectively organized relatively (x ± s) of aged mouse brain tissue protein content and activity of monoamine oxidase
* represent P<0.05
3.2 granule of the present invention is to the active influence of hippocampus of adult rat AchE
[meaning] hippocampus is the major function district of brain learning memory; Acetylcholine participation in learning memory activity; Hippocampus acetyl choline content height can reflect the power of ability of learning and memory; Acetylcholinesterase (TChE) can make the acetylcholine hydrolyzation inactivation, thus medicine active intervention is its one of mechanism of memory that interferes with one's studies to TChE.
[method] got 48 of cleaning level SD female rats, body weight 180~220g, 12 every group, after adaptability fed for 1 week, be divided into 4 groups at random, promptly blank control group and granule height, in,, low, dose groups.Gastric infusion, administration volume are 1ml/100g.Blank control group (with the drug group co-content).Administration every day 1 time; High dose group 8.30gkg-1d-1, middle dosage 3.34gkg-1d-1, low dosage 1.66gkg-1d-1 (more than be the crude drug amount), successive administration 30d; Behind the last administration 1h, all disconnected neck is put to death animal, gets the full brain of mouse on the ice pan fast; Anatomical lens separates hippocampus down, and it is active to measure hippocampal tissue TChE.Sample process and TChE determination of activity are undertaken by the explanation of kit separately requirement.
[result] each group is all relatively seen table 4 with blank group (physiological saline group); Each organizes P<0.01; Difference has statistical significance; The result shows that granule of the present invention possibly be active through reducing the rat hippocampus tissue acetylcholinesterase, raises acetyl choline content indirectly and improves the rat memory, and this possibly be that it improves one of mechanism of learning and memory.
