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 کاملRole of parasympathetic overactivity in water immersion stress-induced gastric mucosal lesion in rat.
Stress ulcer is clinically prevalent, but the underlying mechanisms are not well understood. This study aimed to investigate the role of sympathovagal imbalance in the development of water immersion restraint stress (WRS)-induced gastric mucosal lesion. Wistar rats were subjected to either restraint stress (RS) (n = 7) or WRS (n = 7) for 5 h. Linear parameters of heart rate variability and Poin...
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 کاملProtective effect of fermented papaya preparation on stress-induced acute gastric mucosal lesion
Stress ulceration is single or multiple mucosal defects with/without bleeding from the gastric mucosa during the physiologic stress. Oxidative stress (OS) is a key pathogenic factor in psychogenic stress-induced acute gastric mucosal lesion (AGML). Fermented papaya preparation (FPP) is reported to have oxygen radical scavenging activity and is effective in OS-related diseases. Here, we investig...
