[ 1 ] - Study of Changes in Some Pathophysiological Stress Markers in Different Age Groups of an Animal Model of Acute and Chronic Heat Stress
This study demonstrates the changes in six different pathophysiological parameters such as body weight, body temperature, fecal pellet count, blood-brain barrier (BBB) permeability, plasma corticosterone level and emergence of hemorrhagic peptic ulcer spots due to exposure to high environmental heat in three different age groups of freely moving rats. Methods: Each age group of rats was sub di...
[ 2 ] - Depletion of Serotonin Synthesis with p-CPA Pretreatment Alters EEG in Urethane Anesthetized Rats under Whole Body Hyperthermia
Serotonin is believed as an important factor in brain function. The role of serotonin in cerebral psycho-patho-physiology has already been well established. However, the function of serotonin antagonist in anesthetized subjects under hyperthermia has not been studied properly. Methods: Experiments were performed in three groups of urethane-anesthetized rats, such as: (i) control group, (ii) wh...
[ 3 ] - An Assessment of Changes in Open-Field and Elevated Plus-Maze Behavior Following Heat Stress in Rats
This paper presents the effect of high environmental heat on behavior of the male Charles Foster rats. Eighty rats were divided into three groups, subjected to (i) acute heat stress (ii) chronic heat stress and (iii) handling control group. Animals were exposed to the hot environment in a biological oxygen demand incubator at 38 ± 1ºC (relative humidity 45-50%) for four hours of continuous sing...
[ 4 ] - Effect of Acute and Chronic Heat Exposure on Frequency of EEG Components in Different Sleep-Wake State in Young Rats
The recent literatures indicate that central nervous system (CNS) is highly vulnerable to systemic hyperthermia induced by whole body heating on conscious animals. In the present study, cerebral electrical activity or EEG (electroencephalogram) following exposure to high environmental heat has been studied in moving rats. Rats were divided into three group (i) acute heat stress-subjected to a s...
[ 5 ] - Effect of p-CPA Pretreatment on EEG Power Spectra in Experimental Open Brain Injury in Rats
Continuous four hours EEG (electroencephalogram) recordings and its power spectrum analysis using fast fourier transform (FFT) in urethane anesthetized male Charles Foster rats were performed in two groups: open brain injury and p-CPA (para-Chlorophenylalanine) pretreated before brain injury, respectively, and compared with the EEG power spectrum of control rats. The EEG power spectrum analysis...
