摘要: 目的 评价不同剂量AT1受体拮抗剂valsartan 对SHR 的降压疗效及其逆转心肌肥厚作用的影响。方法 18 只14 周龄雄性SHR 随机分成空白对照组、小剂量valsartan 组、大剂量valsartan 组, 另设WKY 正常对照组, 分别给予生理盐水、valsartan 8mg·kg-1、valsartan 24 mg ·kg-1, 每日1 次灌胃给药, 持续8 wk 。结果 药物干预各组SHR 动脉收缩压(SBP)水平明显下降, 尤以大剂量valsartan 组SBP 下降最显著;药物干预各组LVM/BW、TDM均明显减低。结论 不同剂量AT1 拮抗剂均有明显的降低SHR 的SBP 作用, 能明显抑制左室肥厚进展;大剂量用药效果最为显著。

Abstract: Aim To evaluate the effects of different doses of valsartan on blood pressure and left ventricular hypertrophy in spontaneously hypertensive rats (SHR). Methods Eighteen SHR (fourteen-week-old, male) were divided into three groups (six rats in each group): SHR control group in which the rats were fed with normal saline; low dose valsartan group in which the rats were fed with valsartan 8 mg·kg-1·d-1 and high dose valsartan group in which the rats were fed with valsartan 24 mg·kg-1·d-1、all for 8 weeks. The rats in the WKY control group (n=6) were fed with normal saline for 8 weeks. Results SBP, LVM/ BW and TDM of SHR were remarkably lower than those of the control after drug intervention and the effect on SBP LV M/ BW and TDM was most remarkable in the high dose valsartan group. Conclusion Different doses of valsartan can decrease SBP of SHR and inhibit the progression of ventricular hypertrophy.
