Emblica officinalis outcome on noise stress induced behavioural changes in Wistar albino rats

Ameliorative Effects of Kaempferol and Zinc Gluconate on Erythrocyte Osmotic Fragility and Haematological Parameters in Wistar Rats Exposed to Noise Stress

“…This further shows that noise plays a role in the homeostasis of the immune system. Evidence that noise stress induces immunosuppression [55] and oxidative stress has been implicated in noise-induced immunosuppression [2]. The finding of the present study agrees with that of Minka and Ayo ( [50] who obtained an increase in lymphocyte counts following ascorbic acid supplementation in transported goats exposed to heat stress.…”

“…Noise stress induction: Noise stress was induced using a modification of the method described by Wankhar et al [2]. Briefly, noise was produced by a loud speaker (15 W), installed at a distance of 30 cm above the cages for Groups II to V, and driven by a white noise generator (DT-8850; Shenzhen Technology Co. Ltd., Shenzhen, Guangdong, China), emitting frequencies in the range 0-20 kHz.…”

“…Noise is stressful and activates the hypothalamo-pituitary-adrenal (HPA) axis, resulting in the release of corticosteroid hormones from the adrenal gland into circulation, and may cause hearing loss and other health impairments such as headache, hypertension, coronary and other cardiovascular diseases [2,10]. Haematology is important in evaluating the health and nutritional status of an animal [47].…”

“…Stress refers to a non-specific response of the body to unpleasant stimuli, threatening homeostasis and the integrity of the organism [2,3]. It is a state of threatened homeostasis provoked by psychological, physiological and environmental stressors [4].…”

Effects of long-term construction noise on health of adult female Wistar rats

“…(2008) claimed that a 95-dB machine sound changes the haematological parameters of rats such as red blood cell deformability and aggregation. Moreover, long-term noise exposure could lead to an increase in the number of red blood cells, and serum concentration of haemoglobin (Monsefi et al 2006, Wankhar et al 2014.…”
