Trihalomethanes, carbon tetrachloride, 1,1,1-trichloroethane, 1,2-dibromoethane, chlorinated benzenes, ethylbenzene, and naphthalene at concentrations commonly found in surface and groundwater were incubated under anoxic conditions to study their transformability in the presence of denitrifying bacteria. None of the aromatic compounds showed significant utilization relative to sterile controls ...

ASZMT (Cu, Ag, Zn, Mo, TEDA impregnated) carbon was prepared by impregnation of active carbon with ammonical salts of Cu (II), Ag (I), Zn (II), Mo (VI) and TEDA using incipient wetness technique. Thereafter, ASZMT carbon was characterized using scanning electron microscopy, atomic absorption spectroscopy, thermogravimetry and surface characterization techniques. The ASZMT carbon was evaluated u...

background: chemical toxins are among the leading causes of liver disorders, inflammation and necrosis in hepatocytes. the aim of this study was to evaluate of protective effect of hydroalcoholic extract from rhizome of zingiber officinale l. (hez) on carbon tetrachloride-induced hepatic injury in male rat. material and methods: in this experimental studymale wistar rats (n=35, body weight 230-...

The protective effects of 18beta-glycyrrhetinic acid (GA), the aglycone of glycyrrhizin (GL) derived from licorice, on carbon tetrachloride-induced hepatotoxicity and the possible mechanisms involved in this protection were investigated in mice. Pretreatment with GA prior to the administration of carbon tetrachloride significantly prevented an increase in serum alanine, aspartate aminotransfera...

The present study appraised the hepatoprotective activity of aqueous extract of Camellia sinensis leaves and its possible mechanism of action against carbon-tetrachloride-induced liver damage. Liver damage was induced by   intraperitoneal administration of equal mixture of carbon tetrachloride   and olive oil (50 % v/v, 0.5 ml/kg ) in male Wistar rats (150-220g) once daily for...

The antioxidant effect of aqueous-ethanolic extract from Astragalus glycyphylloides (Fabaceae), and its protection against carbon tetrachloride-induced hepatotoxicity were investigated in male Wistar rats. For seven consequent days the animals were treated orally with A. glycyphylloides extract (EAG) (100 mg/kg). Two hours after the last administration the animals were charged with carbon tetra...

Recent work in our laboratory, carried out in collaboration with Dr. M. C. Schotz, has led to the formulation of a simple hypothesis regarding the pathogenesis of carbon tetrachloride fat accumulation. This hypothesis consists essentially of an extension of the work of Byers and Friedman (1) to the carbon tetrachloride-poisoned liver. These workers have recently shown that the liver is constant...

1. The effects of a number of free-radical scavengers and other agents on the stimulation of malonaldehyde production due to low concentrations of carbon tetrachloride have been studied in rat liver microsome suspensions. 2. Promethazine, propyl gallate and NN'-diphenyl-p-phenylenediamine were extremely active in inhibiting the stimulation of malonaldehyde production due to carbon tetrachloride...
