1. This study examines the effects of exercise training and chronic ethanol consumption on cholinesterase activity and its relationship to lipid peroxidation in blood and brain regions of rat. 2. Exercise training (6.5 weeks) decreased acetylcholinesterase (AChE) activity significantly (64% of control) in hypothalamus and increased AChE activity in cerebral(More)
This study investigates the effect of ethanol ingestion on antioxidant enzymes (AOE) and lipid peroxidation (malondialdehyde, (MDA) in different brain regions of the rat after acute exercise. Acute exercise (100% VO2max) significantly increased glutathione peroxidase (GSH-Px) activity and decreased glutathione reductase (GR) activity in the cerebral cortex.(More)
This study investigates the interactive effects of chronic ethanol ingestion and exercise training on the antioxidant system and lipid peroxidation in cortex, cerebellum, medulla, striatum and hypothalamus of the rat brain. Exercise training (6.5 weeks) significantly increased superoxide dismutase (SOD) activity in striatum, the region associated with motor(More)
This study investigated the response of the antioxidant defense system in brain subcellular fractions after oral graded doses of ethanol to rat. Four groups of male Fischer-344 rats were orally administered saline, ethanol 2 g, 4 g, and 6 g/kg, respectively, and sacrificed 1 hour post treatment. Brain cytosol, synaptosomes, microsomes and mitochondria were(More)
1. This study elucidates the interaction of acute exercise and single ethanol intake on cholinergic enzyme and its relationship to lipid peroxidation in the blood and brain regions of the rat. 2. Butyrylcholinesterase (BuChE) in plasma and acetylcholinesterase (AChE) in brain regions as well as lipid peroxidation (MDA) were assayed in 1) sedentary control(More)
Carboplatin is currently being used in the clinic against a variety of human cancers. However, high dose carboplatin chemotherapy resulted in ototoxicity in cancer patients. This is the first study to show carboplatin-induced oxidative stress response in the cochlea of rat. Male Wistar rats were divided into two groups of six animals each and treated as(More)
Carboplatin, a platinum-containing anticancer drug, is currently being used against a variety of cancers. However, a single high dose of carboplatin is ototoxic in cancer patients. This is the first study to show carboplatin-induced hearing loss in a rat model. Male Wistar rats were divided into five groups and treated as follows: (1) control (saline,(More)
Carboplatin is currently being used as an anticancer drug against human cancers. However, high dose of carboplatin chemotherapy resulted in hearing loss in cancer patients. We have shown that carboplatin-induced hearing loss was related to dose-dependent oxidative injury to the cochlea in rat model. However, the time response of ototoxic dose of carboplatin(More)
Chronic alcohol consumption induces multi-organ damage, including alcoholic liver disease (ALD), pancreatitis and hypertension. Ethanol and ethanol metabolic products play a significant role in the manifestation of its toxicity. Ethanol metabolizes to acetaldehyde and produces reduced nicotinamide adenine dinucleotide (NADH) by cytosolic alcohol(More)
This study was designed in order to evaluate alterations in the reactive oxygen species (ROS) scavenging system in olfactory bulb, dorsal neocortex and cerebellum for 6 weeks following a single subcutaneous dose (600 mg kg-1) of diethyldithiocarbamate (DDTC) to rats. A single dose of DDTC caused substantial damage to the olfactory epithelium and(More)
