Abstract:
Objective To investigate the expression of adiponectin Mrna in adipose tissues of spontaneously hypertensive rats (SHR) and the effects of Fosinopril (Fos) and osartan (Los) on adiponectin Mrna.Methods Twenty 22 - week old male SHR rats were randomly divided into four groups:SHR group,Fos group,and Fus + Los group.Five 22 - week old male WKY rats were used as control.The body weigh,cuff-tail blood pressure,urinary microprotein and urinary N-acetyl-β-D-glucesaminidase were determined.RT-PCR were applied to determine the expression of adiponectin Mrna in adipose tissues.Results At the eighth week,systolic blood pressure of rats in SHR group was significantly higher than those in the other four groups (P＜0.05).The levels of urinary microprotein,urinary NAGase in the WKY group,Fos group,Los group and Fos + Los group were significantly lower than those in SHR group(P＜0.05).RT-PCR analysis revealed that the expression of adiponectin Mrna in SHR group was obviously decreased,compared with WKY goup.Adiponectin Mrna expression in Los group,Fos group and Fos + Los group were increased compared with SHR group(P＜0.05).Conclusions The expression of adiponeetin Mrna is down-regulated in adipose tissues of SHR.After intervention with Fusinopril and Losartan,the adiponectin Mrna expression was up-regulated in adipose tissues of SHR,the levels of urinary microprotein and urinary NAGase were obviously increased in SHR and the levels of urinary microprotein and urinary NAGase were obviously decreased.
