Biochemical changes in acute noise stress in rats.

Stereological Estimation of Granule Cell Number and Purkinje Cell Volume in the Cerebellum of Noise-Exposed Young Rat

In spite of the existing reports on behavioural and biochemical changes related to the cerebellum due to noise stress, not much is known about the effect of noise stress on the neuronal changes in the cerebellum. The present study aims at investigating the effects from one week noise exposure on granule cell number and Purkinje cell volume within the neonate rat cerebellum.15-day-old male Wista...

Retracted: Time course changes of oxidative stress and inflammation in hyperoxia-induced acute lung injury in rats

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...

Antidiabetic effect of honey feeding in noise induced hyperglycemic rat: involvement of oxidative stress

Objective(s):In this study the effect of oral administration of honey on serum glucose, lipids, stress oxidative markers, and morphology of langerhans islets in noise induced hyperglycemic rats was investigated. Materials and Methods: Male Wistar rats were divided into control, hyperglycemic, honey treated control, and honey treated hyperglycemic groups. For induction of hyperglycemia, noise s...

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...

Time course changes of oxidative stress and inflammation in hyperoxia-induced acute lung injury in rats

Objective(s):Therapies with high levels of oxygen are commonly used in the management of critical care. However, prolonged exposure to hyperoxia can cause acute lung injury. Although oxidative stress and inflammation are purported to play an important role in the pathogenesis of acute lung injury, the exact mechanisms are still less known in the hyperoxic acute lung injury (HALI).   Materials ...
