Changes of CCl4-induced of Liver Injury in Rats for 24 Hours / 中国实验方剂学杂志

ABSTRACT

Objective:To replicate the animal model of liver injury in rats by using carbon tetrachloride (CCl4), investigate the dynamic changes of early biomarkers of liver injury, namely glutamate dehydrogenase (GLDH), purine nucleotide phosphorylase(PNP), α-dynamic changes of glutathione-S-transferase (α-GST) and arginase 1(Arg1), and provide experimental evidence for early detection of acute liver injury. Method:Forty-eight Wistar rats were randomly divided into a blank group and a model group. The model group was intraperitoneally injected with 10 mL·kg-1 10% CCl4 olive oil solution, fasting but except water. Animals were sacrificed at 3, 6, 12, and 24 h. The serum liver function alanine aminotransferase(ALT), aspartate aminotransferase (AST), bilirubin (TBIL), alkaline phosphatase (ALP) levels, α-GST, Arg1, GLDH, PNP levels, and liver homogenate superoxide dismutase (SOD), glutathione (GSH), malondialdehyde (MDA) levels were then detected. Result:As compared with blank group, the levels of ALT, AST, TBIL, α-GST, Arg1, GLDH, PNP and MDA were increased significantly 3 h after administration, and SOD was decreased significantly(Pα-GST, ARG-, GLDH, TBIL, ALP and MDA were increased significantly, while GSH and SOD were decreased significantly (PPα-GST, Arg1, TBIL, ALP and MDA were significantly increased, while GSH and SOD were significantly decreased (PConclusion:α-GST, Arg1, GLDH and PNP have better sensitivity than traditional liver function test indicators, and can be used for early detection of liver injury induced by CCl4 in rats.
