Protective impact of lycopene on ethinylestradiol-induced cholestasis in rats.

Protection against cholestasis and its consequences are considered an essential issue to improve the quality of a patient's life and reduce the number of death every year from liver diseases. Lycopene, a natural carotenoid, has antioxidant scavenger capacity and inhibits inflammation in many experimental models. The present study aimed to elucidate the potential protective effects of lycopene, in comparison to silymarin, in a rat model of cholestatic liver.

Neurochemical, neurobehavioral and histochemical effects of therapeutic dose of l-dopa on striatal neurons in rats: Protective effect of virgin coconut oil.

Despite the fact that levodopa has proven its effectiveness in treating the symptoms of Parkinson's disease (PD), increasing concerns have emerged about its possible long-term toxic effects on dopamine (DA) neurons. The study investigated the possible ameliorative effect of virgin coconut oil against l-dopa- induced neurotoxicity in adult rats. A total number of 40 rats were divided into four groups.

Hydrogen peroxide modulates redox status, energy metabolism, and gene expression in a dose- and time-dependent manner in rat liver.

Aim: The aim of this study was to investigate the effect of three different hydrogen peroxide (H O ) levels on blood and liver oxidative status, energy metabolites, and gene expression in male albino rats at two time intervals (2 and 4 weeks).

Methods: A total of 32 rats were divided into four groups. The first group received tap water and served as control.

Prophylactic effects of ellagic acid and rosmarinic acid on doxorubicin-induced neurotoxicity in rats.

Doxorubicin (DOX) is a chemotherapeutic agent widely used in human malignancies. Its long-term use cause neurobiological side effects. The aim of the present study was to investigate the prophylactic effect exerted by daily administration of ellagic acid (EA) and rosmarinic acid (RA) on DOX-induced neurotoxicity in rats.
