目的分析易脑卒中型肾血管型高血压大鼠(RHRSP)血超敏C反应蛋白(hs-CRP)、一氧化氮(NO)及肿瘤坏死因子(TNF)-α的变化规律。方法选取健康雄性SD大鼠36只进行1~36数字编号,再随机分为研究组和对照组各18只,研究组采用双肾双夹法造RHRSP模... 目的分析易脑卒中型肾血管型高血压大鼠(RHRSP)血超敏C反应蛋白(hs-CRP)、一氧化氮(NO)及肿瘤坏死因子(TNF)-α的变化规律。方法选取健康雄性SD大鼠36只进行1~36数字编号,再随机分为研究组和对照组各18只,研究组采用双肾双夹法造RHRSP模型,对照组采用假手术方法(不上银夹);观察两组术前、术后第1、2、4、8、12、16周的收缩压(SBP)、舌下静脉血NO、CRP及TNF-α的水平变化规律。结果术前两组SBP、CRP、TNF-α差异无统计学意义(P>0.05),术后第1、2、4、8、12、16周研究组SBP值显著高于对照组(P<0.05),且呈现出明显的上升趋势,与术前比较显著增高(P<0.05)。术前两组NO测定值差异无统计学意义(P>0.05),术后第1、2、4、8、12、16周两组NO值差异显著(P<0.05);研究组呈现出明显的上升趋势,在术后第2周达到最高值后逐渐下降,与术前比较差异显著(P<0.05)。结论 RHRSP大鼠存在血管壁内皮功能异常和炎症反应,CRP、TNF-α、SBP升高及NO降低可能是脑卒中发生的机制之一。 展开更多

Objective: To explore the direct and/or the enhancing antihypertensive effects of wind-dispelling herbs involvingFangfeng (Saposhnikoviae Radix) and Baizhi (Angelicae dahuricae Radix) using liver-yang hyperactivity renalhypertension rat. Methods: Model rats with hyperactivity of liver-yang hyperactivity were prepared using male SD rats.Once successful, the rats were randomly divided into groups and given medicine by gavage for 4 weeks. Blood wascollected from the abdominal aorta to prepare serum. Serum nitric oxide (NO) concentration was determined bychemical colorimetry. The contents of ET, TXB2 and 6-K-PGF1a were determined by enzyme linked immunosorbentassay (ELISA). Results: Compared with the control model group, the blood pressure, serum ET and TXB2 of rats in thewind dispelling medicine group was not significantly reduced, while those of rats in captopril group, Tianma GoutengDecoction I group (TGD group) decreased significantly (P 〈0.05 for both). Interestingly, the blood pressure, serum ETand TXB2 of rats in the combination group (wind dispelling medicine & TGD) decreased significantly compared withboth wind dispelling medicine group and TGD group. Meanwhile, the levels of serum NO and 6- K-PGF1a in thecombination group was much higher than those in the wind dispelling medicine group or TGD group (P 〈0.05 for both).However, the levels of serum NO and 6- K-PGF1a in the wind dispelling medicine group was not significantly increasedcompared with the model group. Conclusion: There is no direct pressure lowering effects of wind dispelling medicinealone, while wind dispelling medicine could potentiates the antihypertensive effects of Tianma Gouteng Decoction I.Besides, the synergistic effects may be related to decreased ET and TXB2 levels and the increased NO and 6- K-PGF1alevels. 展开更多
