Hypothalamic Astrocytes Respond to Gastric Mucosal Damage Induced by Restraint Water-Immersion Stress in Rat
Restraint water-immersion stress (RWIS), a compound stress model, includes both psychological and physical stimulation. Studies have shown that neurons in the hypothalamus are involved in RWIS, but the role of astrocytes and the interactions between astrocytes and neurons in RWIS are not clear. Here, we tested our hypothesis that hypothalamus astrocytes are involved in RWIS and interact with ne...
متن کاملProtective effects of escin against water immersion and restraint stress-induced gastric ulcer in mice
Background: Escin was a natural mixture of triterpenoid saponin that was isolated from the seed of the horse chestnut. The previous study from our laboratory demonstrated that escin had a protective effect against indomethacin-induced gastric ulcers in mice. The aim of this study was to investigate the effect of escin on gastric mucosal lesions induced by water immersion and restraint stress (W...
متن کاملGastroprotective effects of β3-adrenoceptor agonists on water immersion plus restraint stress-induced gastric ulcer in rats
Objective: To evaluate the gastroprotective effects of β 3 -adrenoceptor agonists CGP 12177A and SR 58611A, on water immersion plus restraint stress (WIRS)-induced gastric ulceration in rats. Material and Methods: Drugs were administered (5, 10 and 15 mg/kg, p.o. ) 30 min prior to the ulcerogenic procedure. Ulcer index and the score for intensity of intraluminal bleeding were determined. Gastri...
متن کاملPalm vitamin E reduces catecholamines, xanthine oxidase activity and gastric lesions in rats exposed to water-immersion restraint stress
BACKGROUND This study examined the effects of Palm vitamin E (PVE) and α-tocopherol (α-TF) supplementations on adrenalin, noradrenalin, xanthine oxidase plus dehydrogenase (XO + XD) activities and gastric lesions in rats exposed to water-immersion restraint stress (WIRS). METHODS Sixty male Sprague-Dawley rats (200-250 g) were randomly divided into three equal sized groups. The control group ...
متن کاملComparative proteomic analysis of rats subjected to water immersion and restraint stress as an insight into gastric ulcers
In the present study, comparative proteomic analysis was performed in rats subjected to water immersion‑restraint stress (WRS). A total of 26 proteins were differentially expressed and identified using matrix‑assisted laser desorption/ionization time of flight mass spectrometry. Among the 26 differentially expressed protein spots identified, 13 proteins were significantly upregulated under WRS,...
