目的:
2
通过比较对乙酰氨基酚(APAP)致肝损伤模型大鼠传统生物标志物丙氨酸氨基转移酶(ALT),天冬氨酸氨基转移酶(AST),碱性磷酸酶(ALP),总胆红素(TBIL)和潜在生物标志物谷氨酸脱氢酶(GLDH),嘌呤核苷酸磷酸化酶(PNP),
α
-谷胱甘肽-
S
-转移酶(
α
-GST),精氨酸酶1(Arg1)的变化来判断GLDH,PNP,
α
-GST,Arg1是否可以作为检测药物性肝损伤的早期生物标志物。
方法:
2
48只大鼠随机分为2组,分为正常组、模型组,每组24只,雌雄各半。给予模型组灌胃1 250 mg·kg
-1
APAP溶液复制药物性肝损伤的模型,在给予APAP后3,6,12,24 h,每个时间点每组随机取6只大鼠(雌雄各半),检测血清ALT,AST,ALP,TBIL,GLDH,PNP,
α
-GST,Arg1水平及肝组织匀浆GLDH,PNP,
α
-GST,Arg1水平;苏木素-伊红(HE)染色检查肝组织病理学变化。
结果:
2
与正常组比较,模型组大鼠血清和肝组织匀浆的ALT,AST,ALP,TBIL,GLDH,PNP,
α
-GST,Arg1水平均明显升高(
P
<
0.05,
P
<
0.01),表明APAP致药物性肝损伤模型复制成功。模型组大鼠血清和肝组织的GLDH,PNP,
α
-GST,Arg1水平比ALT,AST水平升高时间早,幅度大。
结论:
2
GLDH,PNP,
α
-GST,Arg1较传统肝功能检测指标具有较好的灵敏性,可以作为早期检测药物性肝损伤的生物标志物。
Objective:
2
To determine whether glutathione dehydrogenase (GLDH)
purine nucleotide phosphorylase (PNP)
α
-glutathione-
S
-transferase (
α
-GST)
and arginase 1 (Arg1) can be used as the early biomarkers of drug-induced liver injury by comparing the changes of traditional biomarkers alanine aminotransferase (ALT)
aspartate aminotransferase (AST) and alkaline phosphatase (ALP)
total bilirubin (TBIL) and potential biomarkers GLDH
PNP
α
-GST and Arg1 in acetaminophen (APAP)-induced liver injury model rats.
Method:
2
The 48 rats were randomly divided into two groups: blank group and model group. 24 rats in each group
half male and half female. The model group received 1 250 mg·kg
-1
APAP solution by intragastric administration to establish the drug-induced liver injury. 6 rats (half male and half female) were randomly selected from each group at 3
6
12 and 24 h after APAP was given to the model group
to detect the levels of ALT
AST
ALP
TBIL
GLDH
PNP
α
-GST
Arg1 in serum and levels of GLDH
PNP
α
-GST
Arg1 in liver tissue homogenate at each time point Histopathological changes of liver tissues were observed by hematoxylin-eosin (HE) staining.
Result:
2
As compared with the blank group
the levels of ALT
AST
ALP
TBIL
GLDH
PNP
α
-GST and Arg1 in serum and liver homogenates were significantly increased in model group(
P
<
0.05
P
<
0.01)
indicating that the APAP-induced liver injury model was successfully replicated. GLDH
PNP
α
-GST and Arg1 levels in serum and liver tissues of rats in the model group were increased earlier and more significantly than ALT and AST levels.
Conclusion:
2
GLDH
PNP
α
-GST and Arg1 can be used as biomarkers for early detection of drug-induced liver injury.
