Effect embodiment:
1, the provide protection of medicine A-E to rat cerebral ischemia
1.1 laboratory animal and grouping
Wistar male rat, body weight 250-300g, animal rearing is in there being circadian Animal House, and envrionment temperature is controlled at 20 ℃ of left and right, humidity 55% left and right, rat can ad lib and drinking-water.Adapt to after 3 days at Animal House, rat random packet, is divided into sham operated rats (but performing an operation not modeling), model group (modeling is not still treated), medicine (A-E) injection group and positive drug nimodipine group.The experiment administration cycle is one week, and wherein injection preparation group gives intravenously administrable 0.5mg lyophilized injection/kg, and control group gives the physiological saline of equivalent, in the administration of carrying out for the 1st, 4,7 days of experiment.
The foundation of 1.2 animal models
Animal after last administration 1 hour with 3% vetanarcol the dosage intraperitoneal injection of anesthesia with 30mg/kg, femoral arteriography recording blood pressure, femoral venous catheter is for filling with again, plastics tubing inserts right atrium for bloodletting from external jugular vein.Continuous recording electrocardiogram(ECG (EEG), with the method bloodletting of blood drawing, lose blood and while reaching 10.7pKa (80mmHg), separate bilateral common carotid arteries ligation, continue again blood drawing, in the time that blood pressure drops arrives 6.7pKa (50mmHg), the wave amplitude of EEG is very low, but does not disappear, now cause incomplete cerebral ischemic model, maintain 15 minutes.Sham operated rats is only performed an operation, not ligation bilateral common carotid arteries.
The mensuration of 1.3 experimentation on animals parameters
1.3.1 brain water content is measured
After 15 minutes, get 10 animals for every group, open cranium and get brain, after removal rhinencephalon, brain stem, cerebellum, claim brain weight in wet base, then put into baking box and bake to constant weight, claim dry weight, calculate brain water content.
Brain water content calculates according to following formula:
Brain water content=(brain weight in wet base-brain stem weight)/brain weight in wet base × 100%
1.3.2 study of behaviour scoring is observed
Animal is postoperative revive after, separately get 10 animals for every group, carry out study of behaviour condition grading, standards of grading are without 0 point of behavioral function disappearance symptom; Carry rat tail and see that paralysis side forelimb reclaims flexing and can not normally stretch to 1 point, ground; During to a thruster, feel resistance compared with 2 points of the obvious reductions of offside; When rat creeps to 3 points of sideway swivels; With 4 points of the disturbances of consciousness.
1.3.3 cerebral tissue Necrosis volume is measured
Get at random 10 rats in postoperative, after anesthesia, broken end is got brain, removes olfactory bulb, cerebellum and low brain stem, and remaining part is crown is immediately cut into 5, is placed in 2% TTC solution and dyes, and necrotic area is pale asphyxia, be normally redness.Measure the necrosis area of each layer with image analysis system, total area sum is multiplied by bed thickness and is volume (mm
3).
1.4 statistical analysis
Each group rat is observed the data obtained with mean ± standard deviation (x ± s) represent.Between group, carry out t check.
1.5 experimental result
1.5.1 the impact of medicine on rat brain water content
The results are shown in Table 1: sham operated rats brain water content is 75.1%, and model group brain water content is 83.8%.Two groups of comparing differences are remarkable, illustrate that model that this time experiment is done can cause the obvious oedema of cerebral tissue.Have and obviously alleviate cerebral edema effect (p < 0.01) with model group comparative drug A-E group; And the result for the treatment of of medicine group A-E is all better than nimodipine group (p < 0.05).
The impact (n=10) of table 1 different dosing group on rat brain water content
With control group comparison
###p < 0.05, with relatively * P < 0.05**P < 0.01 of model group
1.5.2 study of behaviour scoring observations
The results are shown in Table 2
The impact (n=10) that table 2 different dosing group is learned rat behavior
With relatively * P < 0.05**P < 0.01 of model group
1.5.3 cerebral tissue Necrosis volume measurement result
The results are shown in Table 3.
The impact (n=10) of table 3 different dosing group on cerebral tissue Necrosis volume
With relatively * P < 0.05**P < 0.01 of model group
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 ischemic brain injury, play extraordinary therapeutic action, its result for the treatment of is significantly better than clinical application.
