During the past 10 years, the use of methamphetamine (METH) has significantly increased in Iran and around the world. The widespread use of 3,4-methylenedioxymethamphetamine as a recreational drug has been responsible for the incidence of several cases of liver failure in young people. This issue made researchers focus on METH toxicity due to the lack of(More)
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)
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)
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)
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)
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)
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)
Lithium preparations are commonly used drug in treating mental disorders and bipolar diseases, but metal’s cytotoxic mechanisms have not yet been completely understood. In this study, we investigated the cytotoxic mechanisms of lithium in freshly isolated rat hepatocytes. Lithium cytotoxicity were associated with reactive oxygen species (ROS) formation and(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)
