Thallium (Tl) is a highly toxic heavy metal though up to now its mechanisms are poorly understood. In this study, we comparatively investigated the cytotoxic mechanisms of Tl(I) and Tl(III) in isolated rat hepatocytes. Both Tl(I) and Tl(III) cytotoxicities were associated with reactive oxygen species (ROS) formation, lipid peroxidation, collapse of(More)
The protective effects of different concentrations of aqueous extract of Rhus coriaria L. fruit (75 and 100 microg/ml) and also gallic acid (100 microM) as one of its main components were examined against oxidative stress toxicity induced by cumene hydroperoxide (CHP) in isolated rat hepatocytes. Both extract concentrations and gallic acid (100 microM)(More)
Cisplatin is widely used chemotherapeutic agent for the treatment of several human malignancies. Dose-related nephrotoxicity is the major adverse effect of cisplatin. The cellular and molecular mechanisms behind the cisplatin nephrotoxicity have not yet been completely understood. In this study, cytotoxic effect of cisplatin on renal proximal tubular (RPT)(More)
Although valproic acid (VPA) a proven anticonvulsant agent thought to have relatively few side-effects VPA has been referred as the third most common xenobiotic suspected of causing death due to liver injury. In this study the cellular pathways involved in VPA hepatotoxicity were investigated in isolated rat hepatocytes. Accelerated cytotoxicity mechanism(More)
1.  Methamphetamine (METH) is a highly addictive stimulant that is among the most widely abused illicit drugs. Clinical evidence has shown that the liver is a target of METH toxicity. The exact cellular and molecular mechanisms involved in METH-induced hepatotoxicity have not yet been completely understood. 2.  In this study, the cellular pathways involved(More)
Thallium(I) is a highly toxic heavy metal; however, up to now, its mechanisms are poorly understood. The authors' previous studies showed that this compound could induce reactive oxygen species (ROS) formation, reduced glutathione (GSH) oxidation, membrane lipid peroxidation, and mitochondrial membrane potential (MMP) collapse in isolated rat hepatocyte.(More)
Valproic acid (VPA), an anticonvulsant and mood-stabilizing drug, is widely used for the treatment of different types of seizures and myoclonic epilepsy. Several mechanisms have been suggested for VPA hepatotoxicity, and most of them are associated with oxidative stress. It seems that oxidative stress by VPA treatment has been associated with mitochondrial(More)
The initial objectives of this study were to evaluate the extent of 3, 4-methylenedioxymethamphetamine (MDMA) induced loss of cell viability (cytotoxicity), induction of reactive oxygen species formation and damage to sub-cellular organelles (e.g. mitochondria/lysosomes) in freshly isolated rat hepatocytes under normothermic conditions (37 degrees C) and to(More)
In this research, we investigated the cytotoxic mechanisms of one of the widely used pharmaceuticals that are regularly associated with the adverse effects on the liver, sometimes leading to acute liver failure, diclofenac. Diclofenac liver cytotoxicity was associated with reactive oxygen species (ROS) formation and lipid peroxidation which were inhibited(More)
Mango (Mangifera indica L.) and their components are commonly used in folk medicine for many curative effects. The protective effects of different concentrations of aqueous extract of Mangifera indica L. fruit (Mango Extract) (20, 50 and 100 microg/ml) and also gallic acid (100 microM) as a pure compound in the extract were examined against oxidative stress(More)
