Immune mechanisms in tienilic acid associated hepatotoxicity.
In order to investigate the mechanisms underlying the hepatotoxicity associated with tienilic acid (Ticrynafen) ingestion we have looked for evidence of sensitisation to drug altered liver cell determinants using an indirect antibody dependent, cell mediated cytotoxicity assay (ADCC). As targets, hepatocytes were isolated from rabbits pretreated with either tienilic acid or its isomer with or w...
متن کاملMechanisms of circadian rhythmicity of carbon tetrachloride hepatotoxicity.
The toxicity of carbon tetrachloride (CCl(4)) and certain other chemicals varies over a 24-h period. Because the metabolism of some drugs follows a diurnal rhythm, it was decided to investigate whether the hepatic metabolic activation of CCl(4) was rhythmic and coincided in time with maximum susceptibility to CCl(4) hepatotoxicity. A related objective was to test the hypothesis that abstinence ...
متن کاملMolecular Mechanisms Associated with Hepatotoxicity of Carbonyl Compounds
Hepatotoxicity represents a serious adverse health effect caused by a number of xenobiotic chemicals. This effect is generally detected at the later stages of drug development or with in vivo (whole animal) studies. Both the chemical structure and reactivity of an organic compound have significant impact on its mode of action, and, hence, the anticipated hepatotoxic effects. Currently, there is...
متن کاملMechanisms of alcohol-induced hepatotoxicity: studies in rats.
Alcohol treatment results in increases in the release of endotoxin from gut bacteria and membrane permeability of the gut to endotoxin, or both. Females are more sensitive to these changes. Elevated levels of endotoxin activate Kupffer cells to release substances such as eicosanoids, TNF-alpha and free radicals. Prostaglandins increase oxygen uptake and most likely are responsible for the hyper...
متن کاملCurrent Concepts of Mechanisms in Drug-Induced Hepatotoxicity
Drug-induced liver injury (DILI) has become a leading cause of severe liver disease in Western countries and therefore poses a major clinical and regulatory challenge. Whereas previously drug-specific pathways leading to initial injury of liver cells were the main focus of mechanistic research and classifications, current concepts see these as initial upstream events and appreciate that subsequ...
