Sham operation group and model group were normally bred after model establishment, and 6 h after model establishment, the treatment group received intragastric administration of Peiyuan Huayu Decoction, and control group received intragastric administration of Piracetam Tablets, 1 time a day. On the 1d, 3d, 5d and 7d after model establishment, the general conditions of rats (activity, food intake and mental state) were observed, blood was collected via auricula dextra, ELISA method was used to determine peripheral plasma NSE and S100β protein contents, routine HE staining was conducted after perfusion fixation, the neurons in blood injection side of brain tissue were counted, and the neuron damage was observed.Results: 26 rats were dead in the experiment. The general conditions of sham operation group were significantly better than those of other groups, treatment group was significantly better than model group and control group on the 5d group (P<0.05), and there was no significant difference on the 1d, 3d and 7d (P>0.05);neuron count of sham operation group was basically stable, treatment group was not different from model group and control group on the 1d (P>0.05), treatment group was better than model group (P<0.05), and not different from control group (P>0.05) on the 3d, and treatment group was better than model group and control group on the 5d and 7d (P<0.05);peripheral plasma S100β protein and NSE contents of sham operation group were at lower levels, treatment group was not significantly different from model group and control group on the 1d (P>0.05), S100β protein and NSE contents decreased significantly on the 3d, and treatment group was significantly different from model group and control group (P<0.05), S100β protein and NSE contents increased on the 5d and 7d, the increase in treatment group was slower than that in model group and control group, and there was significant difference (P<0.05).Conclusion:Peiyuan Huayu Decoction has obvious protective effect on the neurons in ASDH model rats, and this effect may be based on the inhibition of secondary neuron damage.展开更多

Materials and Methods:...Objective: To explore the effects of Peiyuan Tongnao(PYTN) Capsule on working memory, the content of glutamic acid, and the expression of NMDA receptor 2 B(NR2 B) in rats with cerebral ischemia. Materials and Methods: 52 Sprague-Dawley rats were randomly divided into sham group, model group, nimodipine group, and PYTN group. The bilateral common carotid artery occlusion(BCAO) was performed to establish rat model with cerebral ischemia in the model, nimodipine, and PYTN groups. Gastric lavage with some drug based on body weight conversion was performed daily for 4 weeks in the nimodipine and PYTN groups. The working memory of the rats was tested by Morris water maze. The expression of Nissl body in hippocampus tissue was observed by Nissl staining. The determination of Glu content in hippocampus was detected by high-performance liquid chromatography. The expression level of NR2 B in hippocampus area was determined using Western blot. Results: Morris water maze test on working memory escape latency. In the model group, day 1 versus day 4, there was a statistical difference(P < 0.05). In the nimodipine group, day 1 vs. day 4 displayed a statistical difference(P < 0.05).In the PYTN group, day 1 versus day 3 and day 1 versus day 4 were in significant differences(P < 0.05). The Glu content in hippocampus of the sham group was significantly different from that of model group(P < 0.05). The Glu content in the PYTN group was significantly different from that of the model group(P < 0.05). With regard to the expression of NMDA 2 B in hippocampus between the sham group and the model, nimodipine, and PYTN groups, all were displayed statistical significance(P < 0.01). As the same, the expression of NMDA2 B in the model group was significant from that of the nimodipine group(P < 0.05) and PYTN group(P < 0.01). Conclusion: PYTN capsule was beneficial for improving working memory and protect neural cells in rats of cerebral ischemia, which may be associated with upregulation of the expression of Glu and NMDAR2 B in hippocampus.展开更多
