RESUMO

The alcoholic liver disease usually causes overall immunological alterations which might be attributed to hepatic disease, to ethanol action, and/or to malnourishment. In the present study, efficacy of lecithin with vitamin-B complex to treat ethanol induced immunomodulatory activity was compared with the effect of lecithin alone and tocopheryl acetate (vitamin E). Ethanol (1.6 g/kg body wt/day for 12 weeks) exposure increased thiobarbituric acid reactive substance (TBARS) level, while decreased superoxide dismutase (SOD) activity and reduced glutathione (GSH) content in whole blood hemolysate of 8-10 week-old male BALB/c mice (weighing 20-30 g). The activities of transaminase (AST and ALT) enzymes, interleukin (IL)-10 and gamma interferon (IFN-gamma) elevated, while IL-2 and IL-4 reduced in mice serum due to ethanol exposure. These suggested that oxidative stress and immunomodulatory activities were interdependent and associated with ethanol induced liver damage. Lecithin treatment significantly reduced AST (32.44%), ALT (32.09%), IL-10 (25.63%) activities and TBARS content (12.76%) compared to ethanol treated group. However, lecithin with vitamin-B complex treatment, significantly reduced AST (62.83%); ALT (61.96%); IL-10 (35.88%); IFN-gamma (22.55%) activities and TBARS content (31.58%), while significantly elevated GSH content (36.49%) and SOD activity (61.21%). Tocopheryl acetate treatment significantly reduced AST (62.83%); ALT (61.54%); IL-10 (36.35%): IFN-gamma (23.28%) activities and TBARS content (35.84%). while significantly elevated GSH content (28.76%) and SOD activity (62.42%) compared to ethanol treated group. These findings persuasively argued that lecithin with vitamin-B complex was a new promising therapeutic approach in controlling ethanol induced immunomodulatory activities involving liver damage processes. Prevention of oxidative stress with correction of nutritional deficiency caused alteration in the ethanol-induced immunomodulatory activities and associated liver diseases.

RESUMO

The activities of phosphatases and transaminases were studied in muscle and liver of the fresh water fish, Oreochromis mossambicus on exposure to different sublethal concentrations (0.25, 0.5, 0.75 and 1 mgl(-1)) of cartap hydrochloride (insecticidal derivative from marine polycheate) for 96 h. There was an overall decrease in phosphatases and transaminases activity in muscle and liver of the fish subjected to cartap hydrochloride.

RESUMO

The effect of Himoliv (HV) was evaluated in carbon tetrachloride or paracetamol induced hepatotoxicity in rats. Liver necrosis was produced by administering single dose of either carbon tetrachloride (CCl4, 1 ml/kg, 50% v/v with olive oil, s.c.) or paracetamol (PC, 1 g/kg, p.o.). The liver damage was evidenced by elevated levels of serum glutamate oxaloacetate transaminase (SGOT), serum glutamate pyruvate transaminase (SGPT) and serum alkaline phosphatase (ALP) and hepatic thiobarbituric acid reacting substances (TBARS) and superoxide dismutase (SOD). HV pretreatment (0.5 and 1.0 ml/kg, p.o.) significantly (P < 0.001) reduced CCl4 or PC-induced elevations of the levels of SGOT, SGPT, ALP and TBARS, while the reduced concentration of SOD due to CCl4 or PC was reversed. Silymarin (25 mg/ kg, p.o.), a known hepatoprotective drug showed similar results.
