Crataegii Fructus is commonly used as a improving digestion, removing retention of food, promoting blood circulation and resolving blood stasis agent in East Asia. Cadmium (Cd) is widely distributed in the environment due to its use in industry. An exposure to Cd causes dysuria, polyuria, chest pain, hepatic and renal tubular diseases. The liver is the most important target organ when considering Cd-induced toxicity because Cd primarily accumulates in the liver. This study investigated the protective effect of Crataegii Fructus water extract against cadmium ($CdCl_2$, Cd)-induced liver toxicity in H4IIE cells, a rat hepatocyte-derived cell line and in rats. Cell viability was significantly reduced in Cd-treated H4IIE cells in a time and concentration-dependent manner. However, Crataegii Fructus water extract (CFE) protected the cells from Cd-induced cytotoxicity via inhibition of PARP cleavage. To induce acute toxicity in rats, Cd (4 mg/kg body weight) was dissolved in normal saline and intravenously injected into rats. The rats then received either a vehicle or silymarin (as a positive control) or CFE (50, 100 mg/kg/day) for 3 days, and were subsequently exposed to a single injection of Cd. Alanine aminotransferase (ALT), aspartate aminotransferase (AST) and lactate dehydrogenase (LDH) were significantly increased by Cd treatment. In contrast, pretreatment with CFE reduced ALT, AST and LDH. In histopathological analysis, CFE reduced the hepatic degenerative regions and the number of degenerative hepatocytes. These are considered as direct evidences that Crataegii Fructus has favorable inhibitory effects on the Cd-intoxicated liver damages. The efficacy of Crataegii Fructus shows slight lower than that of silymarin in the present study.
