目的
2
观察逍遥散对雷公藤多苷连续灌胃5周所致大鼠肝损伤的防治作用。
方法
2
将31只SD大鼠随机分为4组,分别为正常组、雷公藤多苷组、雷公藤多苷+逍遥散组(治疗组)、雷公藤多苷+逍遥散提前用药1周组(防治组)。雷公藤多苷按37.5 mg·kg
-1
灌胃给药,逍遥散(水煎剂)按19.270 g·kg
-1
灌胃给药。首先防治组每天上午8:00~9:00灌胃逍遥散,其他组灌胃等体积生理盐水。1周后,雷公藤多苷组每天上午8:00~9:00灌胃雷公藤多苷混悬液;治疗组和防治组每天上午8:00~9:00灌胃逍遥散,2 h后再灌胃雷公藤多苷混悬液,给药持续5周。采用苏木素-伊红(HE)染色法观察肝组织病理形态学改变,酶联免疫吸附测定(ELISA)检测各组大鼠血清白细胞介素-1
β
(IL-1
β
),白细胞介素-6(IL-6),肿瘤坏死因子-
α
(TNF-
α
)水平,化学法检测天门冬氨酸氨基转移酶(AST),丙氨酸氨基转移酶(ALT),谷胱甘肽过氧化物酶(GSH-Px),超氧化物歧化酶(SOD),微量丙二醛(MDA)水平变化,免疫组织化学染色观测肝组织IL-6,IL-1
β
,TNF-
α
阳性表达情况。
结果
2
与正常组比较,雷公藤多苷组炎细胞浸润,肝细胞水肿,肝血窦受挤压变窄,肝板变宽,肝细胞出现明显坏死,血清IL-1
β
,IL-6,TNF-
α
,ALT,AST,MDA水平显著升高(
P
<
0.01),GSH-Px,SOD水平明显下降(
P
<
0.05,
P
<
0.01),肝组织IL-6,TNF-
α
,IL-1
β
阳性表达显著增强(
P
<
0.01);与雷公藤多苷组比较,治疗组与防治组大鼠肝组织少部分炎细胞浸润,水肿减轻,部分细胞紊乱,血清IL-1
β
,IL-6,TNF-
α
,ALT,AST,MDA水平显著下降(
P
<
0.01),GSH-Px,SOD水平明显升高(
P
<
0.05),肝组织IL-6,TNF-
α
,IL-1
β
阳性表达均显著减少(
P
<
0.01),且防治组疗效更好。
结论
2
逍遥散在一定程度上能明显缓解雷公藤多苷所致长期肝毒性,且提前预防性给药效果较佳。
Objective
2
To observe the preventive and therapeutic effects of 5-week administration with Xiaoyaosan on rat liver injury caused by tripterygium Glycosides.
Method
2
Thirty-one SD rats were randomly divided into 4 groups, namely normal group, tripterygium glycosides group, tripterygium glycosides+Xiaoyaosan group (treatment group), and tripterygium glycosides+Xiaoyaosan for 1 week in advance group (prevention group). Tripterygium glycosides (37.5 mg·kg
-1
) was administered intragastrically, and Xiaoyaosan (water decoction, 19.270 g·kg
-1
) was administered intrastrically. First, the rats of prevention group were intragastrically administrated with Xiaoyaosan at 8:00-9:00 am, and the rats of other groups were given an equal volume of normal saline. After 1 week, the rats of tripterygium glycosides group were administered intragastrically with tripterygium glycosides suspension at 8:00-9:00 am. The rats of the treatment group and the prevention group were intragastrically administrated with Xiaoyaosan at 8:00-9:00 am, and then tripterygium glycosides suspension 2 hours later. All the drugs were given once a day for 5 weeks. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of liver, enzyme-linked immunosorbent assay (ELISA) was used to detect serum interleukin-1
β
(IL-1
β
), interleukin-6 (IL-6) and tumor necrosis factor-
α
(TNF-
α
), chemical method was used to detect the content changes of aspartate aminotransferase (AST), alanine aminotransferase (ALT), glutathione peroxidase (GSH-Px), superoxide dismu-tase (SOD), trace malondiamine aldehyde (MDA). Immunohist-ochemical staining was used to observe the expressions of IL-6, IL-1
β
and TNF-
α
in liver tissue.
Result
2
Compared with the normal group, the tripterygium glycosides group showed inflammatory cell infiltration, hepatocyte edema, hepatic sinuses squeezing and narrowing, liver plate widening, and liver cell necrosis, the contents of serum IL-1
β
, IL-6, TNF-
α
, ALT, AST and MDA were significantly increased(
P
<
0.01), but the contents of GSH-Px and SOD were decreased significantly (
P
<
0.05,
P
<
0.01), while the positive expressions of IL-6, TNF-
α
, IL-1
β
in liver tissue were significantly increased (
P
<
0.01). Compared with tripterygium glycosides group, rats in the treatment group and the prevention group had less inflammatory cells infiltration and reduced edema in the liver tissue, and disorders in some cell, the contents of serum IL-1
β
, IL-6, TNF-
α
, ALT, AST, MDA were significantly decreased (
P
<
0.01), the contents of GSH-Px and SOD were significantly increased (
P
<
0.05), and the positive expressions of IL-6, TNF-
α
, IL-1
β
in liver tissues were significantly decreased (
P
<
0.01), with a better efficacy in the prevention group.
Conclusion
2
Xiaoyaosan can obviously alleviate the long-term liver toxicity caused by tripterygium polyglycoside to a certain extent, with a better prophylactic effect.
