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.

Key words: Xijiao Dihuang decotion, LPS, fever, IL-1β, PGE2
