Abstract:
Objective To investigate the change rule and correlation of heme oxygenase-1(HO-1)/carbon monoxide(CO)and the influence of simvastatin and amlodipine in athemsclemtic progress.Methods The rabbits received 1％cholesterol diet(n=24)for eight weeks.After eight weeks,rabbits were fed with normal diet for eight weeks.The rabbits in model group(n=8)were administrated with cholesterol diet.The rabbits in simvastatin group(n=8)were administrated with simvastatin.The rabbits in amlodipine group(n=8)were administrated with amlodipine.The levels of serum lipids and plasma carbon monoxide were obtained at the beginning,the 8th week and the 16th week.The expression of heme oxygenase-1 in the thoraoia aortic tissue were observed with immunohistochemistry technique.Results By the end of 16th week,the levels ofserum lipids and plasma carbon monoxide in model group were obviously increased,however,the expression of heine oxygenase-1 were markedly decreased.Compared with model group.The levels～rurfl lipi&and plasma carbon monoxide in simvastatin group were significantly decreased,while the expression of heme oxysenase-1 in aortic great reduced.The levels flerum lipids in amlodipine group were not significant ckmged,the levels of plasma carbon monoxide were obviously decreased,while tlle expression ofheine oxygenase-1 in aortic great reduced.Conclusions In atheresclerofic progress,heme oxygenase-1(HO-1)/carbon monoxide(CO)appared the reciprocal relationship,and amlodipine may suppress athemsclemtie progress by decreasing the system.
