Effect embodiment:
Experiment one
SD rat, male and female half and half, body weight 200g.Stay one group of rat as normal control, all the other rat modelings.After rat anesthesia, be fixed on stereotaxic instrument, wipe out art district hair, partly sterilised, the sagittal otch of 1.5cm is done in center, the crown, and blunt separation periosteum, with reference to rat brain stereotaxic atlas, in the each hole that bores a diameter 1mm of the each corresponding point of bilateral skull, be dissolved in the amino-(3-hydroxy-5-isoxazolyl)acetic acid. solution 1ul (containing amino-(3-hydroxy-5-isoxazolyl)acetic acid. 5ug) of the pH7.4 phosphate buffer of 0.1 mole with the vertical injection of microsyringe.5 minutes inject time of every pin, let the acupuncture needle remain at a certain point 5 minutes, and partly sterilised after rear suture operation otch returns that cage is conventional raises after clear-headed.After modeling success, by rat random packet, be divided into model control group, gavage gives normal saline; Positive drug treatment group, gavage gives galanthamine hydrobromide, and dosage is 10mg/kg; Medicine A group, intramuscular injection, dosage is 10mg/kg; Medicine B group, intramuscular injection, dosage is 5mg/kg; Medicine C group, intramuscular injection, dosage is 1mg/kg; Medicine D group, intramuscular injection, dosage is 2mg/kg; Medicine E group, intramuscular injection, dosage is 0.5mg/kg.After administration, use classical Morris water maze to carry out behavioristics's detection.Water maze is diameter 90cm, the round pool of high 40cm, and depth of water 30cm, indicates 4 place of entry on pool wall, be divided into 4 quadrants, places a circular platform at the 3rd quadrant center, platform is lower than water surface 2cm, 25 ℃ of water temperatures.Each group rat carries out respectively water maze laboratory for one week after administration.Test event is sea trial, water maze laboratory first three day, every day trained rat 3 times.After training, rat is put into pond from 4 place of entry respectively towards pool wall, survey in its 90 seconds and successfully find platform required time, i.e. escape latency, does not find platform if rat enters after water in 90 seconds, is placed on platform and stops 10 seconds.The results are shown in Table 1.
Escape latency test result after the administration of the each treatment group rat of table 1 (unit: second, n=20)
Experiment two
Wistar rat, male and female half and half, body weight 200g.Stay one group of rat as normal control, all the other rat modelings.After rat anesthesia, be fixed on stereotaxic instrument, wipe out art district hair, partly sterilised, with reference to rat brain stereotaxic atlas, right substantia nigra position coordinate is positioned, then at twice 6-hydroxy dopamine is injected to right substantia nigra portion with microsyringe and set up rat model.After modeling success, random packet, is respectively model group matched group, and gavage gives normal saline; Positive controls, gavage gives body of Pramipexole dihydrochloride, and dosage is 1.5mg/kg; Medicine A group, intramuscular injection, dosage is 10mg/kg; Medicine B group, intramuscular injection, dosage is 8mg/kg; Medicine C group, intramuscular injection, dosage is 0.5mg/kg; Medicine D group, intramuscular injection, dosage is 2mg/kg; Medicine E group, intramuscular injection, dosage is 0.1mg/kg.After administration completes, respectively organize the apomorphine of rats by intraperitoneal injection 0.01%, bring out rat circling behavior, record the number of revolutions in each group of rat 1 minute.The results are shown in Table 2.
Number of revolutions comparison (n=20) after the administration of the each treatment group rat of table 2
Experiment three
Wistar rat, male, body weight 200g.Stay one group of rat as Normal group, all the other rat modelings.After rat anesthesia, be fixed on stereotaxic instrument, with reference to rat brain stereotaxic atlas, divide and four times quinolinic acid is injected to right side surcingle shell core and set up rat model with microsyringe.After modeling success, random packet, is respectively model group matched group, and gavage gives normal saline; Positive drug control group, gavage gives tetrabenazine, and dosage is 8mg/kg; Medicine A group, intramuscular injection, dosage is 5mg/kg; Medicine B group, intramuscular injection, dosage is 10mg/kg; Medicine C group, intramuscular injection, dosage is 0.5mg/kg; Medicine D group, intramuscular injection, dosage is 1.5mg/kg; Medicine E group, intramuscular injection, dosage is 0.1mg/kg.After administration 12 hours, each group of rat carried out to behavioristics's experiment, experimental project is classical spacious experiment.Experimental period is the morning, and spacious experimental box is 100cm × 100cm × 50cm black inwall opaque plastics case, and bottom surface is divided into the large grids such as 25 20cm × 20cm.Before experiment, plastic box is cleaned and eliminates residual abnormal smells from the patient, experiment is carried out under quiet environment.Rat is placed in and records rat after plastic box and climbed lattice at 5 minutes and count summation, erect number of times.The number of times of standing more than two fore paw built on stilts 1cm is for erectting number of times.The results are shown in Table 3.
After the administration of the each treatment group rat of table 3, climb the statistics (n=20) that lattice are counted summation (A), erect number of times (B)
Comprehensive above-mentioned experimental result is reached a conclusion: compound (A), (B), (C), (D), (E) medicine of preparing all can obviously improve the symptom of neurodegenerative diseases, plays the very well therapeutical effect to neurodegenerative diseases.
