RESUMO
【Objective】To observe the effect of Modified Sini Powder(MSP)on the expression of hippocampal neuronal nitric oxide synthase(nNOS)in rats with chronic psychological stress.【Methods】Twenty-four Wistar rats were randomized into 3 groups: normal group,model group(receiving random stress stimulation for 21 days),and MSP group(receiving gastric infusion of MSP 3.38 g for each rat one hour before stimulation).The normal group and the model group received the same volume of saline.The expression of hippocampal nNOS was detected with immunohistochemical method.【Results】nNOS expression was found in neuronal pyramidal cells of hippocampus CA3 area in the three groups.The expression was obvious,positive cell count and its scoring were increased in the model group as compared with the normal group(P
RESUMO
This paper presents the results of pharmacological studies on Zhi Tan Ling (ZTL). The results showed that ZTL could decrease the ischemic damage of the brain tissue in case of acute cerebral ischemia and increase synthetic metabolism, promote restoration of Cerebral thrombosis, increase cerebral blood flow, improve hemorheologic indexes and meningeal microcirculation in experimental animals. It is indicated that ZTL is effective for ischemic apoplexy through various mechanisms.
