An in vitro system was used for investigating transport of rapidly labeled RNA from liver nuclei isolated from control and thioacetamide-treated rats. An enhanced transport was observed in preparations from thioacetamide-treated animals. Analysis of transport at various temperatures indicated that it proceeded as an energy-requiring process, even in the absence of an exogenously added energy so...

This investigation was concerned with the acute effect of ethionine, thioacetamide, dimethylnitrosamine (DMN), or aflatoxin B, on hepatic polyribosomes and protein synthesis of rats fed purified diets either ad libitum for 3 to 29 weeks containing 0.025% N-2-fluorenylacetamide (2FAA) or 0.06% 3 -methyl-4-dimethylaminoazobenzene (3 Me-DAB) or by force-feeding for 3 days of diets containing 2-FAA...

R. tomentosus is a vegetal species closely related to the culinary rosemary (R. officinalis), a plant reported to contain antihepatotoxic agents. A dried ethanol extract of the aerial parts of Rosmarinus tomentosus (Lamiaceae) and its major fraction separated by column chromatography (fraction F19) were evaluated for antihepatotoxic activity in rats with acute liver damage induced by a single o...

BACKGROUND AND PURPOSE Hepatic encephalopathy is a neuropsychiatric disorder of complex pathogenesis caused by acute or chronic liver failure. We investigated the effects of cannabidiol, a non-psychoactive constituent of Cannabis sativa with anti-inflammatory properties that activates the 5-hydroxytryptamine receptor 5-HT(1A) , on brain and liver functions in a model of hepatic encephalopathy a...

The ameliorative activity of aqueous extract of the flesh of dates (Phoenix dactylifera L.) and ascorbic acid on thioacetamide-induced hepatotoxicity was studied in rats. Sixty male rats were divided into six equal groups of 10. Two groups were controls, one treated with thioacetamide and one with only distilled water. Two groups received extract of flesh Phoenix dactylifera and intraperitoneal...

BACKGROUND/AIMS Dietary nucleotides modulate a number of metabolic processes, including long-chain polyunsaturated fatty acid metabolism. In this study, we evaluated the effect of dietary nucleotides on plasma and liver microsomal fatty acid profiles in a rat model of liver cirrhosis induced by oral intake of thioacetamide. METHODS Fifty-four female Wistar rats were assigned to one of the fol...

Administration of thioacetamide to rats was found to increase the activity of liver messenger RNA in the wheat germ protein synthesis assay. The synthesis of total protein was increased about 2.5-fold after 4 days of treatment. The treatment was associated with an increase in the relative quantity of polyadenylic acid-containing RNA. Immunoprecipitation studies showed that albumin synthesis dir...

caused by thioacetamide (20 mg/kg body weight) in albino rats for a period of eight week. A significant (p<0.05) improvement in the altered levels of bilirubin, albumin, total protein, alanine transaminase, alkaline phosphatase, γ-glutamyl transferase was observed after treatment with 10 ml/kg body weight of Nigella sativa oil. Antioxidant enzymes like catalase, superoxide dismutase glutathione...

1. The concentrations of the nicotinamide-adenine dinucleotides in rat liver have been determined at intervals during the period 1-24hr. after feeding adult female rats with dimethylnitrosamine or thioacetamide. 2. The administration of dimethylnitrosamine resulted in a rapid decrease in the sum of NAD+NADH(2). This sum was decreased by 40% 3hr. after dosing. 3. Dimethylnitrosamine administrati...

This investigation was concerned with the acute effect of ethionine, thioacetamide, dimethylnitrosamine (DMN), or aflatoxin B, on hepatic polyribosomes and protein synthesis of rats fed purified diets either ad libitum for 3 to 29 weeks containing 0.025% N-2-fluorenylacetamide (2FAA) or 0.06% 3 -methyl-4-dimethylaminoazobenzene (3 Me-DAB) or by force-feeding for 3 days of diets containing 2-FAA...
