Objective To investigate the effects of the serum contained Shuluo sterile powder for injection (SLI) on injury induced by anoxia and hypoglycemia in cultured PC12 cells. Methods Cultured PC12 cells were treated with Na2S2O4 and Earle′ s liquid with glucose free to induce models of anoxia and hypoglycemia. The protective effects of the serum contained SLI on the two kinds of models were evaluated by the activity of lactate dehydrogenate (LDH) and staining with MTT assay. Results The serum contained SLI counteracted the injury induced by anoxia and hypoglycemia to various degrees and prevent the efflux of LDH. Conclusion The serum contained SLI can protect PC12 cells from injury induced by anoxia and hypoglycemia.

Objective To observe the influence of bony extracts of Myospalox fontanierii(MF)on immune function in rats with hypersensitive reactive inflammation induced by Freund's complete adjuvant(FCA).Methods Levels of lymphocyte transferring factor(TF)and interleukin-1(IL-1)were detected by immunological methods.Results Extracts of MF reduced the levels of IL-1 and TF in rats with hypersensitive reactive inflammation induced by FCA;it could also depressed the lymphocytic transformation rate.Conclusion Extracts of MF exert inhibitory effect on rats with hypersensitive reactive inflammation induced by FCA and its mechanism may be related with immunosuppressive action and the inhibition of IL-1 formation.

Objective To investigate the effect of Shuluo Injection on cerebral water volume,cerebral index ,LDH,NOS and SOD in the brain.Methods The model of cerebral ischemia-reperfusion in mice is set up by separating the bilateral common carotid artery (CCA) of the mice,blocking the blood stream by straining the thread and by reperfusion loosing the thread. After 3 times of ischemia-reperfusion,brain samples were prepared to observe the cerebral injury. Results High-dose Shuluo Injection significantly reduced the cerebral water volume and decreased the cerebral index and the activity of LDH and NOS(P

AIM: To study the anti-inflammatory,analgesic and antipyretic effects of Qinzhi Capsule(Radix Scutellariae,Fructus Gardeniae,etc). METHODS: Qinzhi Capsule was taken orally.The experimental methods were as follow: abdomen capillary permeability in mouse induced by actetic acid,mouse ear swell induced by dimethylbenzene,mouse pain threshold induced by heat stimulation,animal fever induced by yeast to rat and endotoxin to rabbit,et al. RESULTS: Qinzhi Capsule could inhibit markedly the increase in abdomen capillary permeability in mouse induced by acetic acid(P

Objective To observe the rat chronic toxicity induced by Yinghuang freeze-dried powder injection. Methods The rats were given Yinghuang freeze-dried powder injection for 35 days with the doses of 166.5, 82.25, 41.12 mg/kg and for 15 days of stopping administration. The index sign of hematology and biochemistry were determined, and the pathological examination were carried out. Results The rat were given Yinghuang freeze-dried powder injection for 35 days and for 15 days of stopping administration. Mostly index sign of hematology and biochemistry had no significant difference by comparing with the control. There exceptional index sign of exceptional dosage group have significant difference by comparing with the control. But these exceptional index sign fluctuated in normal range in the laboratory. The pathological examination did not discover significant pathological changes related to drug toxicity. Conclusion Yinghuang freeze-dried powder injection has no significant toxicity for long-term administration on rats. It infers that the drawing up doses in clinic will be safe.

Objective To explore the mechanism of Huagan Jiedu decoction in treatment of chronic hepatitis B by testing the influence of the decoction on Serum IL-2, IL-4 and IFN-γ of rat models of chronic hepatic injury. Methods The model of Chronic hepatic injury was established by subcutaneously injecting 40% CCl4-olive oil solution in rats according to the ratio of 3ml per kg. of body weight. 60 healthy rats were divided randomly into a normal group, a model group, a low dose of Huagan Jiedu decoction group, a large dose of Huagan Jiedu decoction group, and a control group (Qingre Jiedu tablet group), 15 cases in each group. The Serum IL-2, IL-4 and IFN-γ were detected in each group separately. Results Compared with the normal group, the Serum IL-2 and IFN-γ were decreased (t=2.401, 2.337, P=0.0349, 0.0378) and the Serum IL-4 was increased (t=2.896, P=0.00861 ) in the model group; Compared with the model group, the Serum IL-2 and IFN-γ were increased (t=2.417, 2.344, P=0.0341, 0.0372, P<0.05; t=3.114, 2.988, P=0.0052, 0.0068) in the large Huagan Jiedu decoction group and the control group, while the Serum IFN-γ was increased (t=3.049, P=0.0062) in the low dose of Huagan Jiedu decoction group and the Serum IL-4 was decreased (t=3.102, 3.017, 2.979, P=0.0061, 0.0065, 0.0069)in both Huagan Jiedu decoction groups and the control group. Conclusion Large dose of Huagan Jiedu decoction has sound therapeutic effects on rats with chronic hepatic injury by decreaseing the content of the Serum IL-4 and increasing IL-2 and IFN-γ, and adjusting th1/th2 balance.

The effect of Compound Danshen injection (CDI) on anesthetized dog models of myocardial ischemia was investigated. The dog models were established by ligation of main branch of left coronary artery. The results showed that CDI reduced the release of serum CK,LDH and MDA and increased the activity of SOD, decreased the scope of myocardial infarction and slowed down the quickened heart beat induced by ischemia. The differences were significant as compared with those in the model group (P
