ABSTRACT

Objective: To explore the mechanism of congestive heart failure (CHF) by observing the effects of Tingli Shengmai Decoction on myocardial fibrosis and expression of TGF-?1 of rats with CHF. Methods: The CHF animal models were duplicated by the abdomen arteriarctia method, and 60 male wistar rats were randomly divided into the sham-operation group, the model group, the high-dose of Tingli Shengmai Decoction group, the low-dose of Tingli Shengmai Decoction group and the positive medicine (Xinbaowan) control group. After 4 weeks common fed, every group rats were given a certain dose of distilled water or medicine. After 8 weeks, hemodynamic parameters were detected, MASSON staining was used in the study of collagen type in left ventricular interstitial tissue, collagen volume fraction (CVF) were measured by image analysis, and expression of TGF-?1 in myocardium were evaluated by immunohistochemical staining. Results: Compared with the sham-operated group, CVF of model control group increased significantly (P

ABSTRACT

AIM: To investigate effect of Wujibaifeng Pills (WJBFP) on osteoporosis of ovariectonmized (OVX) rat. METHODS: Ovariectonmized (OVX) rat model was established to evaluate osteoporosis of which parameters investigated included bone gla protein (BGP), alkaline phosphatase (ALP), bone minera density (BMD), Serum phosphorus and serum total calcium. RESULTS: WJBFP(1.0g/kg,2.0g/kg,4.0g/kg) could enhance the contents of serum estradiol and calcitonin, decrease serum BGP level in OVX rats; It had no effect on serum total calcium and ALP activities but increase level of serum phosphorus; It could enhance BMD, prevent OVX rat from decreasing bone loss without raising body weight; furthermore, it could inhibit both the uterus and adrenal gland atrophy. CONCLUSION: WJBFP might have better prevention on osteoporosis of ovariectionmized rats.

ABSTRACT

AIM: To observe the effect of Xiaoyu Huatan Decoction on the nonalchoholic fatty liver tissue peroxisome preliferator-activated receptor?(PPAR?) expression. METHODS: The nonalchoholic fatty liver disease rat model was fed by high fat forage and the rats were divided into five groups: normal control group,model control group,high-dose of Xiaoyu Huatan Decoction group,low-dose of Xiaoyu Huatan Decoction group,Dongbao Gantai control group.Total RNA of liver was extracted,and the expression of PPAR?mRNA was analyzed by semi-quantitative RT-PCR method.We determined the contents of total cholesterol(TC),triglyceride(TG),free ratty acid(FFA) in serum and the TC,TG in liver tissue homogenate of each group,and the degree of hepatocytic steatosis. RESULTS: Expression of liver tissue PPAR? mRNA in the model group decreased significantly,lipid in blood serum and hepatic tissues increased significantly,liver fat cell greatly denaturalized.After the intervention of medicine,expression of liver tissue PPAR? mRNA of each treatment group increased significantly,lipid in blood serum and hepatic tissues decreased significantly,liver fat cell denaturation was improved. CONCLUSION: Xiaoyu Huatan Decoction can increase the expression of liver tissue PPAR?mRNA of rats,It is likely to be one of the important mechanism for treating fatty liver.
