title: Ameliorative action of cyanobacterial phycoerythrin on CCl(4)-induced toxicity in rats.
abstract: Carbon tetrachloride (CCl(4)) is largely used as solvent in chemical industries. Carbon tetrachloride is also well known for hepatic and renal toxic actions. The in vivo metabolism of carbon tetrachloride to trichloromethyl (CCl(3)) and peroxy trichloromethyl (OOCCl(3)) radicals has been extensively reported to cause acute liver damage like cirrhosis, steatosis and necrosis. We have evaluated protective action of purified cyanobacterial phycoerythrin (C-PE) on carbon tetrachloride-induced hepatic and renal toxicity in male rats. Rats were orally treated with 25 and 50mg/kg BW of C-PE along with CCl(4) (50% CCl(4), 0.5 ml/kg BW, intraperitoneally) for 28 consecutive days. Results demonstrated that C-PE dose-responsively ameliorates CCl(4)-toxicity by significantly decreasing (P<0.05) organs weight, aminotransferases, alkaline phosphatase, glucose, lipid profile, creatinine, uric acid and malondialdehyde (MDA) concentrations with rise in body weight, food intake, hemoglobin, protein, bilirubin and FRAP values. Neither C-PE nor CCl(4) influenced on serum minerals. Hepatic and renal tissues showed significant decline (P<0.05) in malondialdehyde, lipid hydroperoxides and conjugated dienes with rise in SOD, catalase, GPx, GSH, vitamin-E and vitamin-C levels. Presently observed pharmacological effect on CCl(4) toxicity were from tetrapyrrole molecule and to some extent bilirubin biotransformations, as well as metabolic (dietary protein) actions of C-PE.
