电针"丰隆"穴对高脂血症大鼠NO、ET及CGRP的影响

目的：探讨电针“丰隆”穴对高脂血症大鼠血脂的调节作用及作用机制。方法：将80只Wistar大鼠随机分为正常组（喂基础饲料）、模型组（喂高脂饲料）、电针组（喂高脂饲料＋电针“丰隆”）、西药组（喂高脂饲料＋普伐他汀钠灌胃）。检测各组大鼠治疗前后血清总胆固醇（TC）、甘油三酯（TG）、高密度脂蛋白（HDL-C）、低密度脂蛋白（LDL-C）、内皮素（ET）、一氧化氮（NO）以及降钙素基因相关肽（CGRP）的含量变化。结果：①与正常组比较,模型组大鼠体重、TC、TG、LDL-C、ET水平显著升高（P〈0．01,P〈0．05）,HDL-C、NO和CGRP水平明显降低（P〈0．05）。②与模型组比较,西药组、电针组大鼠体重、TC、TG、LDL-C水平明显降低（P〈0．01）,NO和CGRP水平显著升高（P〈0．01,P〈0．05）。③与电针组比较,西药组HDL-C水平显著升高（P〈0．01）,ET水平降低但两组之间差异没有显著性意义（P〉0．05）。结论：①电针组和西药组均对高脂血症大鼠TC、TG、LDL-C、N0以及CGRP具有较好的良性调节作用,并可在一定程度上降低ET水平。

Effects of electroacupuncture at "Fenglong" (ST 40) on NO, ET and CGRP levels in the rat with hyperlipidemia

OBJECTIVE: To probe the regulative effect of electroacupuncture (EA) at "Fenglong" (ST 40) on blood lipids in hyperlipidemia (HLP) rats and the mechanism. METHODS: Eighty Wistar rats were randomly divided into a normal group (fed with basal forage), a model group (fed with high fat forage), an EA group (fed with high fat forage + EA treatment), a western medicine group (fed with high fat forage + Pravastatin sodium). Contents of serum total cholesterol (TC), triacylglycerol (TG), high density lipoprotein-cholesterol (HDL-C), low density lipoprotein-cholesterol (LDL-C), endothelin (ET), nitric oxide (NO) and calcitonin gene-related peptide (CGRP) were determined before and after treatment. RESULTS: Compared with the normal group, the body weight, levels of TC, TG, LDL-C and ET were significantly elevated (P < 0.05, P < 0.01) and the levels of HDL-C, NO and CGRP were significantly decreased (P < 0.05) in the model group; compared with the model group, the body weight, levels of TC, TG and LDL-C were significantly decreased (P < 0.01) and the levels of NO and CGRP were significantly increased in the western medicine group and the EA group (P < 0.01, P < 0.05); compared with the EA group, HDL-C level significantly increased in the western medicine group (P < 0.01), and ET level decreased in the EA group and the western medicine group with no significant difference between the two groups (P > 0.05). CONCLUSION: Both EA and Pravastatin sodium have better benign regulative effects on TC, TG, LDL-C, NO and CGRP and can decrease ET level to a certain extent in the rat of hyperlipidemia.
