[0056] Experimental Example 2 Effects of effective parts of the present invention on the morphology of brain tissue in MCAT rats
[0057] See Experimental Example 1 for grouping, administration methods, and modeling methods. One hour after the last administration (i.e. 24 hours after surgery), the brain was decapitated, fixed with 20% formaldehyde and Carnoy’s solution, and brain slices were taken before and after the optic chiasm. , for HE and toluidine ryany body staining, observation of tissue morphology changes. Image analysis was performed on the results of Nissal staining (three fields of view were taken from the infarct for each sample, and three samples were taken in each group). The results are shown in Table 3.

experiment example 3
[0062] Experimental Example 3 Effects of Effective Parts of the Present Invention on Rat Arteriovenous Bypass Thrombosis
[0063] The rats were randomly divided into five groups, namely the thrombosis model group, Qingnao Xuanqiao Dropping Pills 20mg / kg, 60mg / kg, 180mg / kg groups (respectively equivalent to 2 times, 6 times, 18 times the human dosage), Tianbaoning 24mg / kg group. Intragastric administration was administered once a day for a total of three administrations. Modeling was established one hour after the last administration, and the same amount of drinking water (1ml / 100g body weight) was given to the thrombosis model group, and surgery was performed one hour after the last administration.
[0064] Experimental rats were anesthetized by intraperitoneal injection of 0.35 g / kg 10% chloral hydrate, fixed in the supine position, operated on, and separated the right common carotid artery and left external jugular vein. Connect three sections of polyethylene tubing, one en...
