Protective Effect of Dandelion Leaf Water Extracts on APAP-Induced Liver Injury in Rats and Its Mechanism

Cell Mol Biol (Noisy-le-grand). 2022 May 31;68(5):24-33. doi: 10.14715/cmb/2022.68.5.4.ABSTRACTwith the advent of a large number of drugs in recent years and the aggravation of human aging, drug-induced liver injury is increasing year by year. The protective effect of dandelion extract on acetaminophen (APAP) - induced drug-induced liver injury in rats and its specific mechanism was studied by in vitro cell culture. For this aim,twenty healthy SD rats with the same physiological status were divided into model group and normal group, with 10 rats in each group. The drug-induced liver injury model was made by intragastric administration of 1 g/kg APAP for 14 days. The liver function lactate dehydrogenase (LDH), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) were detected to verify the success of the model. After that, the liver tissues were aseptically isolated from the normal group and APAP model group, and the primary hepatocytes were cultured. They were divided into control group (control), liver injury model group (model), medium-dose dandelion extract group (1mm dlwe) and high dose dandelion extract group (2mm dlwe). The cell proliferation activity was detected by CCK-8 cell proliferation activity kit. Cell samples were collected at 72 hours to detect the contents of AST and ALT in cell supernatant. The contents of oxidative stress-activated oxygen (ROS), reduced glutathione (GSH) and glutathione peroxidase (GSH-Px) were detected by colorimetry, and th...
