白介素1(IL1) 是重要的炎症因子之一, 在肝损伤中起着重要的作用。为研究重组IL1 受体拮抗剂rIL1ra) 对四氯化碳(CCI4) 诱导的肝损伤的保护作用,将24 只Wistar 大鼠随机分为5 组:即正常对照组(n = 5) ,造模组(n = 5) ,rIL1ra 高剂量(0 .5 m g/100 g) 组(n = 5) ,中剂量(0 .2 mg/100 g) 组(n = 5) 和低剂量(o .1m g/100 g) 组(n = 4) 。检测处理6 周末血清肝酶学(ALT,AST) 和肝纤维化指标:Ⅲ型前胶原(Pc Ⅲ) 、透明质酸( HA) 和层粘蛋白(LN) 。结果:与造模组相比较,rIL1ra 各剂量组血清ALT 和AST 的水平下降( P < 0 .001 和P < 0 .01) ,但组间无差异;而对于肝纤维化指标,虽然数值有下降趋势,但只有高剂量才具有统计学意义( P < 0 .05) 。表明rIL1ra(0 .5m g/100 g) 可阻断肝细胞的急、慢性损伤,抑制肝纤维化的形成,从而可间接地反映IL1 参与了CCl4 导致肝损伤的发病过程。
Interleukin 1 (IL 1) is one of the important inflammatory cytokines, plays an important role in liver injury. In order to study the protective effects of recombinant IL-1 receptor antagonist rIL1ra on CCI4-induced liver injury, 24 Wistar rats were randomly divided into 5 groups: normal control group (n = 5 (N = 5), high dose (0.5 mg / 100 g) of rIL1ra group (n = 5), medium dose (0.2 mg / 100 g) And low dose (o .1 g / 100 g) group (n = 4). Serum liver enzymology (ALT, AST) and liver fibrosis indicators: type Ⅲ procollagen (Pc Ⅲ), hyaluronic acid (HA) and laminin (LN) Results: Compared with the model group, the levels of serum ALT and AST in each dose of rIL1ra decreased (P <0.001 and P <0.01), but there was no difference between the two groups; while for the indicators of liver fibrosis, The values showed a downward trend, but only at high doses was statistically significant (P <0 .05). That rIL 1ra (0. 5m g / 100g) can block the acute and chronic liver cell injury, inhibition of the formation of hepatic fibrosis, which can indirectly reflect IL 1 involved in the pathogenesis of CCl4 leading to liver damage.
