The Hepatocurative Effects of Alkaloids on Tetrachloromethane-Induced Hepatotoxicity on Albino Rats.

The study investigated the hepatocurative activity of the bulk alkaloids of in a tetrachloromethane (CCl)-induced hepatotoxicity model in rats. The hepatocurative activity of the alkaloids at 200, 400 and 600 mg/kg doses was demonstrated by the assay of both enzymic and non-enzymic parameters. Sections of the liver were also subjected to histological examinations. Mapping techniques and data visualization approaches were adopted in finding relationships between the enzymic and non-enzymic parameters and the treatment groups. The bulk alkaloids caused dose-dependent effects on both the enzymic and non-enzymic parameters. The bulk alkaloids elicited a significant reduction ( < 0.05) in all liver and antioxidant enzymes activities compared with the untreated. The 600 mg/kg dose caused the restoration of the ALP, ALT and AST to 76.16, 10.72 and 11.83 iU/L respectively similar to the standard butylated hydroxytoluene. The 600 mg/kg dose also caused a slight increase in the activities of SOD, catalase and GPx to 11.45. 1.37 and 11.66 iU/L respectively when compared with the untreated rats. In the non-enzymic assays, the 600 mg/kg dose elicited a significant ( < 0.05) upregulation in the total bilirubin (1.18 mg/100 mL), total protein (3.75 g/dL), HDL (1.80 mMol/L) and vitamin C (2.41 mg/dL) and decrease in the CHOL (3.35 g/dL), TAG (1.85 mMol/L), LDL (0.67 mMol/L), BUN (39.55 mg/dL) and MDA (1.13 nMol/mL) when compared with the untreated rats. The restoration of the natural histo-architecture of the CCl-damaged liver by the alkaloids further evidenced the hepatocurative activity of the bulk alkaloids.
