Notoginseng Radix et Rhizoma (Sanqi), the underground part of Panax notoginseng (Burk.) F. H. Chen (Araliaceae) is commonly used in Chinese medicine for treatment of haemorrhage, haemostasis, swelling, etc. The aerial part including leaves, flowers and fruits are also applied for similar functions. Triterpenoid saponins are considered to be responsible for the biological activities of Sanqi. Up to date, more than 100 saponins have been isolated from theroots, rhizomes, leaves, flowers and fruits of P. notoginseng. The reported saponins can be classified into protopanaxadiol (PPD), protopanaxatriol (PPT), C17 side-chain varied and other types, according to the skeletons of the aglycons. The present review summarizes the saponins isolated from P. notoginseng and their distribution in different medicinal organs, as well as the pharmacological actions on cardiovascular system.

Aim To ascertain whether defibrase has the protective effect against reperfusion injury after cerebral ischemia.Methods 70 renovascular hypertensive rats(RHR) were randomly divided into defibrase group, control group and sham-operated group.Reversible middle cerebral artery occlusion(MCAO) models were produced by the modified. Longa's method,and reperfusion was begun 2 hours after occlusion.Rats in the defibrase group were given defibrase 10 U?kg-1 body weight via femonal intraveneous injection, and in the control group with the same amount of saline. The brain pieces were processed by TTC and HE staining and the infarct size,brain microvessels damage and secondary bleeding were compared between the two groups. Results The volume of infarction in the defibrase group was obviously smaller than in the control group, the damage of brain microvessels was less severe, and the bleeding lesions under optical microscope were less than in the control group. Conclusion Defibrase has protective effect against reperfusion injury post cerebral ischemia.

OBJECTIVE: To study the expression of p35 and p25 in rat after focal cerebral contusion and to provide experimental data for estimating brain injury time. METHODS: Fifty adult male SD rats were randomly divided into 0 h, 6 h, 12 h, 24 h, 3 d, 5 d, 7 d, 10 d after focal cerebral contusion, control and sham-operated groups (5 rats each group). The focal cerebral contusion rat model was established. The expression of p35 and p25 protein of the damage peripheral zone in brain were detected by HE staining, immunohistochemistry and Western blotting at different injury time. RESULTS: A large number of p35 protein and a small amount of p25 protein were expressed in control group and sham-operated group. After focal cerebral contusion, p35 presented unimodal change with time and p25 presented bimodal changes with time. CONCLUSION Expression of p35 and p25 showed different regularity with good time correlation, which could help to estimate the brain injury time.
