丝瓜络对实验性高血脂大鼠的降血脂效应

目的:探讨中药丝瓜络(RLF)对实验性高血脂大鼠的降血脂效果,以及对实验大鼠体重的影响。方法:雄性SD大鼠32只,随机均分为4组:对照(A)组、高脂模型(B)组、高脂+丝瓜络(C)组、丝瓜络(D)组。 A组和D组大鼠每日饲基础饲料,B组和C组给予高胆固醇饲料,C组和D组的大鼠每日经胃灌服丝瓜络煎剂10 mL/kg BW,A组和B组为每日每只经胃灌服饮用水2 mL,实验周期为14 d。结果:(1)实验后B组大鼠的血清胆固醇(TC)和甘油三脂(TG)分别为(4.63±1.10)和(1.13±0.15) mmol/L,显著高于对照(A)组的TC 和 (P<0.01), 而C组的TC 和TG 则显著低于B组(分别为P<0.05及P<0.01);(2)D组大鼠的TC,实验后较给药前有显著降低(P<0.01);(3)在实验的第8d,B组大鼠的血清高密度脂蛋白胆固醇(HDL-C)为(0.61±0.11) mmol/L,显著低于A 组 (P<0.01),而C组HDL-C 与A组没有显著差异(P>0.05);(4)B组大鼠体重实验后显著增加,而 C组的体重在变化与A组相似。结论:丝瓜络对实验性高血脂大鼠有明显的降血脂效应,使实验大鼠的TC和TG显著降低,HDL-C显著升高,而且能显著减轻实验大鼠的体重。

Effects of Retinervus luffae fructus on serum lipid level in experimental hyperlipidemia rats

AIM: To investigate effects of Retinervus luffae fructus (RLF) on level of serum lipid and body weight in hyperlipidemia rats. METHODS: Thirty-two male SD rats were randomly divided into four groups: control group (A), hyperlipidemia group (B), hyperlipidemia RLF group (C), RLF group (D). Both group A and C were fed normal diet every day, while group B and group D fed high fat diet. Meanwhile, group C and D were administered with RLF solution at the dose of 10 mL/kg, respectively for 14 days, while group A and B were administered with drinking water. RESULTS: (1) At the end of experiment, a significant reduction was found in the levels of serum total cholesterol (TC) and triglyceride (TG) of group C animals treated with RLF solution; (2) The levels of serum TC of group D was progressively decreased compared to the level of serum TC at the beginning of experiment; (3) The level of high-density lipoprotein cholesterol (HDL-C) of group C remained unaltered 8d after treatment with RLF solution; (4) The body weight in group C was obviously lower than that in group B. CONCLUSION: RLF had an obvious hypolipidemic effect on hyperlipidemia rats. It can inhibit the decrease in the HDL-C and the increase of body weight in rats.
