Acrylamide (ACR) is a cytotoxic and carcinogenic material. It is a product of a Maillard reaction during the cooking of many types of fried fast food, e.g. potato chip fries, and chicken nuggets. ACR has a severe toxic effect on different body organs. This study investigates the hepatotoxic effect of ACR, and the protective effect of ascorbic acid and silymarin. For this purpose, forty adult, male, albino rats were divided into four groups and received the following treatments for fourteen days: Group I: (the control) normal saline; Group II: ACR only; Group III: ACR and ascorbic acid; and Group IV: ACR and silymarin. Under a light microscope, the liver from rats treated with ACR only presented disturbed liver architecture, degenerated hepatocytes, reduced glycogen contents, congested central vein, and increased collagen fibres with areas of fibrosis. Immunohistochemical examination revealed an increased mean number of CD68-, and α-SMA-positive cells. This indicates the presence of large numbers of stellate macrophages (Kupffer cells) and Hepatic stellate cells (HSCs). The combination of ACR with either ascorbic acid or silymarin resulted in less hepatic degeneration, less fibrosis and fewer CD68 and α-SMA positive cells compared to the ACR only group. In conclusion, treatment with silymarin or ascorbic acid along with ACR appears to alleviate ACR-induced hepatotoxicity with more protection in silymarin treated rats.
