[Effects of lorsartan, fosinopril on myocardial fibrosis, angiotensin II and cardiac remolding in hypertensive rats].

OBJECTIVE: To investigate effects of lorsartan, fosinopril on myocardial fibrosis, angiotensin II and cardiac remolding in the spontaneously hypertensive rats (SHR). METHODS: 16-week-old SHRs were divided randomly into 3 groups: SHR-L (treated with lorsartan), SHR-F (treated with fosinopril) and SHR-C (untreated), each group consisting of 10 rats. After 8 weeks' and 16 weeks' therapeutic period, collagen volume fraction (CVF), perivascular circumferential area (PVCA), plasma and myocardium angiotensin II concentrations were examined by pathological examination with computed processing and radioimmunoassay respectively. RESULTS: (1) Compared with SHR-C after 8 weeks' and 16 weeks' therapeutic period, the systolic blood pressure (SBP) was decreased similarly in both treatment groups. Heart and left ventricular weights, heart weight and eft ventricular mass indexes were lower significantly in both treatment groups than in SHR-C. Left ventricular mass index was reduced to a lower extent in SHR-F group than in SHR-L group after 16 weeks. (2) Compared with SHR-C, CVF, PVCA after 8 weeks and 16 weeks were reduced significantly in SHR-F and SHR-L. Meanwhile, CVF after 16 weeks in SHR-F than in SHR-L. (3) Compared with SHR-C after both therapeutic periods, plasma and myocardium angiotensin II concentrations were increased Significantly in SHR-L, but plasma angiotensin II concentrations were not altered significantly in SHR-F. However, myocardium angiotensin II concentrations were reduced significantly in SHR-F after 8 weeks and 16 weeks in SHR-F. CONCLUSION: Lorsartan, fosinopril inhibit myocardial fibrosis and reverse heart hypertrophy. Fosinopril may be more effective in these above effects than Lorsartan. The mechanism of the both drug's cardioprotective effects was related to inhibition of myocardium rennin-angiotension-aldsteron system.

Raccoon poxvirus rabies virus glycoprotein recombinant vaccine in sheep.

Twenty sheep were divided into groups and inoculated by various routes with recombinant raccoon poxvirus expressing the CVS rabies virus glycoprotein (rRCNV-G) or with raccoon poxvirus (RCNV). The apparent innocuous pathologic responses to each virus coupled with development of high levels of rabies virus neutralizing antibodies in animals vaccinated with rRCNV-G intradermally or intramuscularly suggested that the recombinant is effective and that RCNV would be a suitable substrate for further development of sheep vaccines. Poor antibody response to rRCNV-G given orally implied that it would be relatively harmless if inadvertently ingested by sheep. Virus transmission between vaccinated and sentinel sheep was not observed or detected serologically.

[Anti-hyperlipemia and anti-oxidation effects of xue zhi ling].

92 cases with complete clinical data among 125 hyperlipemia patients were randomly divided into two groups: 51 cases in the Xue Zhi Ling treatment group and 41 cases in the control group with medication of panagin. The drugs were administered to all patients for 12 weeks and the blood lipid was then examined at the 4th, 8th, 12th week after medication respectively. In treatment group, there was the effect of lowering TC, TC-HDL/HDL and raising HDL at the 4th week (P < 0.05). However, there were no significant difference in above-mentioned parameters at the 4th, 8th and 12th week respectively. The experiment also showed that Xue Zhi Ling could reduce TG at the 8th and 12th week (P < 0.05). While there was no significant difference between that of the 8th and 12th weeks. The mean reduction of TC, TG and TC-HLD/HDL were 18.7%, 19.5% and 27.6% respectively, while the elevation of HDL in average was 17.4%. All of the lipid indexes in control group had no significant changes at any stage. In addition, it was shown that Xue Zhi Ling could decrease serum LPO at 12th week (P < 0.05). The results indicated that the Xue Zhi Ling has the effect of regulating the hyperlipemia and anti-oxidation.
