Amlodipine Ameliorates Up-Regulation of ET-1 in Left Ventricle of Hypercholesterolemia Rabbits |
|
| چکیده انگلیسی مقاله |
Objective(s) In addition to antihypertensive effects, amlodipine may exhibit cardiovascular protective effects in heart tissue. The aim of this study was to evaluate the effects of amlodipine and/or high cholesterol diet on blood, heart tissue concentration and mRNA expression of endothelin-1 (ET-1) in male New Zealand white rabbits. Materials and Methods A total of 40 male New Zealand rabbits were divided into four groups: the normal control group, normal group receiving amlodipine, high-cholesterol diet group and high-cholesterol diet with amlodipine group. After 8 weeks, all the animals anesthetized and blood or tissues samples were collected. Results After 8 weeks of a high cholesterol diet, the group with such a diet had a significantly higher ratio of left ventricle (LV) weight to body weight than the control group (P= 0.0001). After treatment with amlodipine for 8 weeks, ET-1 level was reduced considerably in comparison with the control (P= 0.01) and high- cholesterol diet groupes (P= 0.01). Amlodipine consumption caused significant reduction (P= 0.01) in the level of ET-1 in heart tissues of high-cholesterol diet group but it had no remarkable effect on the reduction of heart tissue ET-1 in amlodipine group compared with the control group. Conclusion The present study demonstrates that ventricular prepro-ET-1 mRNA quantitatively increases in the high- cholesterol diet rabbits which results in development of ventricular hypertrophy. It seems that the treatment with amlodipine retards the progression of LV hypertrophy through attenuation of ET-1 levels independent of lipid changes. |
