Objective: To investigate the antiatherosclerotic effect of Wujibaifeng Pills and its mechanism. Methods: Rat dyslipidema was induced by ovariectomy (OVX), the levels of serum lipids, superoxide dismutase (SOD) activities and malondialdehyde (MDA) were detected after 12 weeks with the treatment of wujibafeng pills. Results: Wujibaifeng Pills lowered serum oxidized-low density lipoprotein cholesterol (OX-LDL,P

Objective: To investigate the protective effect and its mechanisms of Jiusuyu on gastric mucosa of acute alcoholism mice.Methods: Acute alcoholism mouse models were set up by intragastric administration of 56? Hongxing Erguotou wine,compared with Gehuajiecheng liquid,the effect of Jiusuyu on gastric mucosa pathological histology,SOD、MDA、NO and ET-1 of acute alcoholism mice were observed.Results: The gastric mucosa of mice in model group appeared obvious bleeding,fester and ulcer;a lot of phlegmonosis cells infiltrating could be seen below mucosa.At the same time the activity of SOD and level of NO in gastric mucosa were decreased(P

Objective: To observe effect of Kechuanning on expression of nuclear factor kB(NF-?B) in lung tissue of bronchial asthmatic rats.Methods: 40 rats were randomly divided into 5 groups: the normal group,the model group,Kechuanning high-dose group(27g/kg),Kechuanning low-dose group(13.5g/kg),GuilongKechuanning control group(0.45g/kg),8 rats in each group.The bronchial asthmatic model was established by egg protein sensibilization and long-term inhalation provocation.The rats of each treatment groups were lavage administration each day from the first time of provocation to execution.After 4 weeks of treatment,the rats were killed and lung tissue were taken to dyeing of HE to be observed.The expression of NF-?B in lung tissue were determined by immunohistochemistry.Result: Compared with the normal group,the thickness of bronchus wall and bronchus smooth muscle,the numbers of eosinophile granulocyte and leukomonocyte,and expression of NF-?B in lung tissue were increased in the model group(P

Objective To observe the effect of Zhongfengkang on the expression of Aquaporin 4 mRNA(AQP-4mRNA) in brain of focal cerebral ischemia rats. Methods The rat model of focal cerebral ischemia was established by inserting nylon thread.The dynamic changes of AQP-4 mRNA expression in the model group at 12th,24th,48th,72nd and 96th hour after cerebral ischemia were examined and the effect of Zhongfengkang on AQP-4 mRNA expression and cerebral edema at 48 th hour after cerebral ischemia was observed.Results At 12th hour after cerebral ischemia,the expression of AQP-4mRNA in the model group increased compared with the sham-operation group,and it arrived to the peak at 72th hour(P

Objective:To investigate the protective effects of Compound Danshen Injection and Benazepril on rats with obstructive nephrosis.Methods:The interstitial nephritis model of rat was established by ligating unilateral ureter. The model rats were given drug Compound Danshen Injection and Benazepril, respectively. The levels of angiotensin Ⅱ (Ang Ⅱ), endothelin (ET 1) and the activity of angiotensin converting enzyme (ACE) in renal tissues were measured. Results: The level of angiotensin Ⅱ of Compound Danshen Injection group was 42.03?13.95pg/mg lower that of pathologic group (80.19?27.31pg/mg). The level of Benazepril group was 32.53?8.07pg/mg. There were significant differences among them. The measuring results of ACE and ET 1 were similiar to that of Ang Ⅱ.Conclusion: Compound Danshen Injection and Benazepril can effectively inhibit the activity of ACE and decrease the levels of Ang Ⅱ and ET 1.

Objective:To study feasibility of preparing artificial antigen by membrane coated with hapten-carrier.To compare the Emodin-BSA membrane antigen immunogenicity and specificity against the liquid antigen.Methods:Emodin-BSA-PVDF membrane was prepared by the method that BSA was coated on PVDF membrane and the BSA was coupled with Emodin-couplint agent derivative.Rats were immunized by subcutaneous implantation.The immunogenicity and antibody specificity were characterized using Emodin-CA or Chrysophanol-CA or Physcion-CA membrane immunoassay. Results: The immunogenicity of Emodin-BSA coated membrane antigen was higher than Emodin-BSA liquid antigen;the specificity for three anthraquinones was almost the same(P>0.05). Conclusion:Emodin antiserum generated using Emodin-BSA coated membrane antigen has a high immunogenicity and specificity to Emodin.The results show it is feasible that membrane coated with hapten-carrier is used as artificial antigen.
