It is known that positive effects of regular aerobic exercise on cognitive functions in humans and also animals; but how to the effects of aerobic exercise in adolescent period is unknown. The present study examined the effects of regular aerobic exercise on spatial memory using the Morris water maze, cell density and apoptosis of hippocampus in adolescent(More)
The administration of methamphetamine to experimental animals results in damage to nigrostriatal dopaminergic neurons. In the present study, we demonstrated that both the acute repeated and the chronic administration of methamphetamine causes an increase in thiobarbituric acid reactive substances, which are indicators of lipid peroxidation, and superoxide(More)
In a previous study we demonstrated that acute footshock stress increased glutathione peroxidase activity in the prefrontal cortex and striatum of adult male rats. Adolescents may respond differently to stress as life stressors may be greater than at other ages. The present study examined the effects of the acute footshock stress on superoxide dismutase(More)
In the present study, we investigated whether erythropoietin (Epo) has a protective effect against cytotoxicity induced by interferon-gamma (IFN-gamma ) and lipopolysaccharide (LPS) in primary rat oligodendrocyte cultures. The possible modulatory effect of erythropoietin on inducible nitric oxide synthase (iNOS) mRNA expression and nitrite production were(More)
Developing brain is much more sensitive to all kind of stressors than the developed brain. Early maternal deprivation causes some behavioural and physiological effects on rats. After the birth, there is no endocrinological response to stressors between post-natal 4 and 14th days, which is called stress-hyporesponsive period (SHRP) in rats. This(More)
The administration of methamphetamine to experimental animals results in damage to dopaminergic neurons. The hypothesis that methamphetamine-induced neurotoxicity is mediated by reactive oxygen species was evaluated. It was found that acute administration of methamphetamine (5 and 15 mg kg(-1)) resulted in production of oxidative stress as demonstrated by(More)
Melatonin has recently been suggested as an antioxidant that may protect neurons from oxidative stress. Acute ethanol administration produces both lipid peroxidation as an indicator of oxidative stress in the brain and impairs water-maze performance in spatial learning and memory tasks. The present study investigated the effect of melatonin against(More)
The administration of methamphetamine to experimental animals results in damage to dopaminergic neurons. In the present study, we demonstrated that a single dose (15 mg/kg) of methamphetamine results in production of oxidative stress as demonstrated by increased thiobarbituric acid reactive substances levels in the rat striatum and prefrontal cortex. In(More)
BACKGROUND In recent times, medical schools have committed to developing good communication and history taking skills in students. However, there remains an unresolved question as to which constitutes the best educational method. Our study aims to investigate whether the use of videotape recording is superior to verbal feedback alone in the teaching of(More)
Limitations and difficulties of clinical characteristics of mental disorders, manifesting in symptoms of body sphere, are described. The conceptions of body and subjective body experience, assuming that body sensations are involved in self-identification and self-ego formation and connected with cognitive, social and cultural aspects of subjective(More)
