PURPOSE Previous studies have shown that physical activity improves learning and memory. Present study was performed to determine the effects of short term and long term treadmill exercise on learning, memory consolidation and retrieval of passive avoidance learning in an animal model. METHODS In this study fifty male Wistar rats with 3-4 months of age were randomly divided into five groups (...

Objectives: This study evaluates the effects of 8 weeks of resistance exercises on the expression of neurotrophins and Trk receptors in Alzheimer model male Wistar rats. Methods: For this purpose, 32 mature male Wistar rats with a mean weight of 230-280 g were chosen and divided into Alzheimer and Sham groups. The rats in the sham group received normal saline, while the ones in the Alzheimer g...

Ineffectiveness of Dexamelhasone for Treatment of Experimental Cerebral Infarction • Ischemic cerebral edema occurring with cerebral infarction may cause increases of intracranial pressure and neurological deficits or death. Certain other types of cerebral edema are influenced by adrenal glucocorticoids; there is conflicting evidence about effects on ischemic edema, largely due to differences i...

Background: In order to investigate the effects of endurance exercise on male reproductive function in relation to oxidative stress. Materials and Methods: a total of 20 male wistar rats were randomly divided into the following groups: control group (n=10) and exercised group (n=10). A protocol of 60 minutes exercise per day, five days per week was followed for 8 weeks. At the end of experiment...

BACKGROUND AND PURPOSE Lacunar infarction accounts for 25% of ischemic strokes, but the pathological characteristics have not been investigated systematically. A new experimental model of lacunar infarction in the miniature pig was developed to investigate the pathophysiological changes in the corticospinal tract from the acute to chronic phases. METHODS Thirty-five miniature pigs underwent t...

BACKGROUND The purpose of this study was to compare a weight-adjusted dose of carbidopa- levodopa as treatment adjunctive to occlusion therapy with occlusion therapy alone in children and adults with different types of amblyopia. METHODS This prospective study included 63 patients with amblyopia classified into two groups, ie, an occlusion group which included 35 patients who received occlusi...

Aims: Metabolic syndrome is a table of abdominal diseases characterized by insulin resistance, obesity, dyslipidemia, and hypertension, it serious risk factor for the development cardiovascular diseases. The purpose this study was to understand how metabolic causes change in myostatin levels, if swimming exercise have protective therapeutic effects fructose mediated model regulating serum level...
