Abstract:
Objective To observe the effect of rosiglitazone on serum NOS/NO in apolipoprotein(apo) E knockout mice.Methods Twenty eight-week-old apoE knockout mice were intragastrically administrated 0.2 ml 5% sodium carboxymethycellulose for 12 weeks to establish the animal models of atherosclerosis,in which half of mice simultaneously received 10 mg?kg~(-1)?d~(-1) rosiglitazone as treatment.Ten wildtype mice were used as the normal control group.All mice were fed on normal chow diet.After 12 weeks,aorta were used for histomorphometric analysis by means of HE.Vessel blood was collected for plasma lipid,NO and NOS.Results Histomorphometric analysis showed that the area of atherosclerosis plaque in mice receiving rosiglitazone was significantly smaller than the mouse models of atherosclerosis,while the plasm lipid,NO and NOS were higher.Conclusion Rosiglitazone can inhibit the development of atherosclerosis,which mechanism is related to the protection of vascular endothelial function.
