摘要:

本研究旨在探讨犀角地黄汤对脂多糖引起大鼠发热的退热效果及其机制。120SD大鼠,随机分为4组,对照组、脂多糖组、阿司匹林组和犀角地黄汤组,每组30只。脂多糖组、阿司匹林组和犀角地黄汤组腹腔注射100 μg·kg-1脂多糖复制大鼠发热模型,2 h后,阿司匹林组和犀角地黄汤组分别灌服阿司匹林(0.04 g·mL1,按体重以10 mL·kg1给药)和犀角地黄汤(1.6 g·mL1,按体重以10 μg·kg1给药);对照组和脂多糖组灌服同体积的生理盐水。检测各组动物基础体温和攻毒给药后每小时肛温,并在2358 h分别从每组中随机选取6只大鼠断头处死,采取下丘脑组织,检测其IL-1β和PGE2的变化。结果表明,与脂多糖组比较,犀角地黄汤能显著缓解脂多糖引起的大鼠体温升高,且在用药后2 h显著降低脂多糖引起的IL-1β(P<0.05)和PGE2P<0.05)的升高,用药后3 h显著降低IL-1β的升高(P<0.05)。说明犀角地黄汤能明显抑制脂多糖引起的大鼠发热,其初期的退热作用机制可能与抑制下丘脑IL-1β的生成,进而抑制发热介质PGE2释放有关。

Abstract:

 The aim of this study was to investigate the effect and mechanisms of Xijiao Dihuang DecotionXJDHon Lipopolysaccharide (LPS) -induced fever in rats. One hundred and twenty rats were randomly allotted into four groups: Control group, LPS group, Aspirin group and XJDH group. There were 30 rats in each group. LPS group, Aspirin group and XJDH group were reproduced by intraperitoneal injection of LPS 100 μg·kg-1, then Aspirin group and XJDH group were drenched with Aspirin (0.04 g·mL110 mL·kg1 in drug delivery according to body weight) and XJDH (1.6 g·mL110 μg·kg1 in drug delivery according to body weight) respectivelyControl group and LPS group were drenched with saline. The basal body temperature was measured before LPS was injected and then 8 h later, 2 h after administration, 6 Hypothalamus samples were collected in each group at the point of 2, 3, 5 and 8 h. IL-1β and PGE2 were measured. The results showed that, compared with LPS group, the temperature in XJDH group were significantly improved; Compared with the control group, IL-1β of LPS group was significantly increased (P<0.05) at 2 h and 3 h, PGE2 of LPS group was significantly increased (P<0.05) at 2 h; Compared with LPS group, XJDH significantly lowered the levels of IL-1β and PGE2 (P<0.05). The above results suggest that XJDH significantly inhibited LPS-induced fever in Rats. The mechanism of initial antipyretic may be related to the inhibition of IL-1β in Hypothalamus, and reduce the release of PGE2.
