Methods: Experimental mice were perfused with different dosages of tetracycline. Eighteen hours later, the serum levels of ALT, AST were measured and the liver tissues were observed by photics microscope to find the relative suitable dosage that can obviously induce acute liver injury. Then the suitable dosage was given in the same way, and the levels of ALT, SOD, MDA, GSH-PS, IL-18 in serum were measured 18, 36, 54, 72 h later respectively. The condition of cell apoptosis was analyzed, and the tissues were observed by photics microscope and electron microscope to find the relative suitable time.
