Hydrogen sulfide (H2S) is a naturally occurring gaseous transmitter, which is important in normal physiology and disease. In the present study, the involvement of H2S in the regulation of the immune response induced by burn injury was investigated in mice. Adult male C57BL/6 mice were subjected to burn injuries and treated with vehicle (0.9% sodium chloride, NaCl; 100 ml/kg body weight; subcuta...
AIM Cerebral vasospasm is the primary cause of morbidity and mortality after subarachnoid hemorrhage (SAH). Hydrogen Sulfide (H < sub > 2 < /sub > S), a gaseous neurotransmitter, is produced in many tissues including the central nervous system (CNS). The vasodilatatory effect of H2S has been shown in the CNS; however, its role in cerebral vasospasm has not been investigated before. MATERIAL A...
Hydrogen sulfide is emerging as an important mediator of vascular function that has antioxidant and cytoprotective effects. The aim of this study was to investigate the role of endogenous H2S and the effect of chronic exogenous H2S treatment on vascular function during the progression of atherosclerotic disease. ApoE(-/-) mice were fed a high-fat diet for 16 weeks and treated with the H2S donor...
Hydrogen sulfide (H2S) is a novel neurotransmitter that has been shown to influence cardiovascular functions as well and corticotrophin hormone (CRH) secretion. Since the paraventricular nucleus of the hypothalamus (PVN) is a central relay center for autonomic and endocrine functions, we sought to investigate the effects of H2S on the neuronal population of the PVN. Whole cell current clamp rec...
Purpose: To examine the hypothesis that in hypertensive diabetic rats hydrogen sulphide (H2S) reduces blood pressure through diuretic action in addition to its vasodilating effect. Methods: Spontaneously hypertensive rats (SHR) and Wistar-Kyoto (WKY) rats were used. SHR were divided into three groups: SHR (II), SHR diabetic (III), and SHR diabetic NaHS-Treated (IV) with a group of WKY (I) rats ...
AIMS Hydrogen sulfide (H2 S) has been widely accepted as a gas neuromodulator to regulate synaptic function. Herein, we set out to determine the effect of H2 S on α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid receptor (AMPAR) and its mechanism. METHODS BS(3) protein cross-linking, Western blot, patch clamp, and biotin-switch assay. RESULTS Bath application of H2 S donor NaHS (50 and ...
Sepsis-induced myocardial injury is a detrimental disorder for intensive care medicine due to its high rates of morbidity and mortality. Data suggest that nuclear factor (NF)-κB serves a critical role in the pathogenesis of myocardial injury. Hydrogen sulfide (H2S) serves an important role in the physiology and pathophysiology of regulatory mechanisms, particularly during an inflammatory reacti...
Hydrogen sulfide (H(2)S) is an endogenous vasodilator in mammals, but its presence and function in other vertebrates is unknown. We generated H(2)S from NaHS and examined the effects on isolated efferent branchial arteries from steelhead (stEBA) or rainbow (rtEBA) trout. H(2)S concentration was measured colorimetrically (CM) and with ion-selective electrodes (ISE) in rainbow trout plasma. NaHS ...
Ischemic stroke is a leading cause of death and disability worldwide, and autophagy may be involved in the pathological process of cerebral ischemia/reperfusion injury. Hydrogen sulfide (H2S) is an endogenous gasotransmitter with protective effects against multiple diseases. Here, we tested the effect of H2S on cerebral ischemia/reperfusion injury in rats. Sodium hydrosulfide (NaHS), an H2S don...
The aim of the study was to investigate the protective effects of sodium hydrosulfide (NaHS), a H2S donor, against hypoxia-induced injury in human umbilical vein endothelial cells (HUVECs) and also to look into the possible mechanisms by which H2S exerts this protective effect. 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay and scratch wound healing assay were chosen to...
