Two or three decades ago chronic liver injury due to drugs was scarcely recognized. Today a wide range of diseases, previously thought to be due to 'natural' causes, is attributed to therapy, although final proof of the cause is often difficult or impossible to achieve. In addition, new drugs have been produced which have subsequently been shown to have hepatotoxic effects. These may only be ma...

This study evaluated the protective effects of Noni fruit juice on acute liver injury induced by carbon tetrachloride (CCl(4)) in female Sprague-Dawley (SD) rats. Liver damage (micro-centrilobular necrosis) was observed in animals pretreated with 20% placebo (drinking water) + CCl(4). However, pretreatment with 20% Noni juice in drinking water + CCl(4) resulted in markedly decreased hepatotoxic...

These experiments have demonstrated that liver glycogen may rise or fall after endotoxin administration, depending upon the antecedent diet and that total adrenalectomy followed by corticosteroid replacement abolishes the glycogenolytic effect of sublethal doses of endotoxin. It is concluded that the derangements of carbohydrate metabolism observed following the administration of sublethal quan...

Philosophic concepts and pragmatic approaches toward improved understanding of the effect of drugs in the hepatocyte are reviewed. No set pattern of studies is advocated but rather observations are encouraged within the framework of studies that provide for varied exposure of the hepatocyte. Clinical usage should be imitated to provide earliest possible indications of toxicity in man. The need ...

Tumor necrosis factor-related apoptosis-inducing ligand (TRAIL), a potential chemotherapeutic agent for cancer, is not thought to be hepatotoxic. We have recently demonstrated, however, that bile acids increase TRAIL-R2/DR5 expression in a human liver cell line and render these cells susceptible to TRAIL-mediated apoptosis. These data suggest TRAIL may be hepatotoxic in cholestasis. The aim of ...

The aims of this study were to investigate the potential benefits of antioxidant, anti-inflammatory, anti-hepatotoxic, and anti-tyrosinase activities of a methanolic extract of fresh tea leaves (FTE) (Camellia sinensis L.). The antioxidant capacity was investigated using three different methods at different temperatures. The anti-inflammatory activity was studied in vitro by the inhibition of 5...

Earthworms have been widely used in traditional medicine for thousands of years. However, it is only during the past few decades, with the development of biochemical technologies, that research on the pharmaceutical effects has been initiated. The present study was carried out to investigate the hepatoprotective and antioxidant properties of indigenous earthworm powder (Perionyx excavatus), usi...

Background: Hepatotoxic effects can occur with the use of toxic drugs or standard doses, but in long term chronic therapy. In addition to drugs, carrageenan also causes hepatotoxic after 12 hours induction intraperitoneally. The effect liver cell repair is highly related antioxidant activity phenolic compounds date seeds. Objective: present study determined total levels and hepatoprotective eth...

Orthosiphon stamineus as medicinal plant is commonly used in Malaysia for treatment of hepatitis and jaundice; in this study, the ethanol extracts were applied to evaluate the hepatoprotective effects in a thioacetamide-induced hepatotoxic model in Sprague Dawley rats. Five groups of adult rats were arranged as follows: Group 1 (normal control group), Group 2 Thioacetamide (TAA) as positive con...
