This study evaluates the effectiveness of Phyllanthus maderaspatensis L. against liver fibrosis in Wistar rats. Hepatic fibrosis was experimentally induced in male rats with CCl4 administration. Animals were then post treated with 200 mg/kg dose of P. maderaspatensis hexane extract (PmHE). Fibrosis was studied using biochemical assays and histopathological techniques. The molecular mechanism of...

The present study clearly showed that chronic exposure to polychlorinated biphenyls (PCBs) at environmentally relevant concentrations can damage juvenile tilapia livers by modulating antioxidant enzyme activities and gene transcription, which affects toxic bioaccumulation and histological congestion. The results suggest that PCBs caused a decrease in the activity of some hepatic antioxidative a...

Background: Diabetes mellitus is an alarming life style disease in the modern world. Exploitation of the anti-diabetic drugs for the amelioration of diabetes and associated life style diseases has become an imperative concern. In this milieu, this study was designed to explore the plausible effects of metformin intervention on hepatic and renal functions in a rat model of alcoholic liver diseas...

Licorice is commonly used as a cure for digestive disorders and as a detoxification agent in East Asia. This study investigated the protective effect of licorice water extract against cadmium (CdCl(2), Cd)-induced liver toxicity in rats. To induce acute toxicity, Cd (4 mg/kg body weight) was dissolved in normal saline and intravenously (i.v.) injected into rats. The rats then received either a ...

Acetaminophen (APAP) is safe at therapeutic levels but causes hepatotoxicity via N-acetyl-p-benzoquinone imine-induced oxidative stress upon overdose. To determine the effect of human (h) pregnane X receptor (PXR) activation and CYP3A4 induction on APAP-induced hepatotoxicity, mice humanized for PXR and CYP3A4 (TgCYP3A4/hPXR) were treated with APAP and rifampicin. Human PXR activation and CYP3A...

Consumption of fruits plays a special role in prevention and treatment of various diseases. Fruits have several compounds with antioxidant properties. Kiwifruit is one of the most popular fruits worldwide and is cultivated in many countries. It is a rich source of several compounds with antioxidant properties such as polyphenols, flavonoids and vitamins. The aim of this study is to evaluate the...

Accurate prediction of human drug toxicity is a vital part of the drug discovery process. However, the safety evaluation process is hindered by the availability and quality of primary human liver models with which to study drug toxicity. In an attempt to overcome this limitation, research has focused on deriving human hepatocytes from a number of sources, including progenitors from fetal and ad...

Amiodarone is a benzofuran class III antiarrhythmic drug used to treat a wide spectrum of ventricular tachyarrhythmias. The parenteral formulation is prepared in polysorbate 80 diluent. We report an unusual case of acute elevation of aminotransaminase concentrations after the initiation of intravenous amiodarone. An 88-year-old Caucasian female developed acute hepatitis and renal failure after ...

OBJECTIVE To report a suspected toxicity in 2 dogs; to discuss therapy and prognosis. SERIES SUMMARY Suspected alpha lipoic acid (ALA) toxicity was diagnosed based on clinical history and compatible laboratory findings in 2 dogs. Case 1 was presented within 10 hours of ALA ingestion, with initial behavioral changes likely due to hypoglycemia. During the course of hospitalization, hypoglycemia...

Three patients are described with recurrent jaundice, upper abdominal pain and rigors attributable to dextropropoxyphene hepatotoxicity. The diagnosis was established in each patient by rechallenge; post challenge hepatic histology is reported in two. Twelve previous patients with probable dextropropoxyphene hepatic toxicity have been described and are reviewed. In 10 of the 15 patients, a clin...
