Hydrogen sulfide (H2S), a well-established member of the gasotransmitter family, is involved in a variety of physiological functions, including pro-nociceptive action in the sensory system. Although several reports have shown that H2S activates sensory neurons, the molecular targets of H2S action in trigeminal (TG) nociception, implicated in migraine, remains controversial. In this study, using...
BACKGROUND Current knowledge indicates that oxidative damage and the following inflammation is pivotal pathway for myocardial cell death. In recent decades, hydrogen sulfide (H2S) has been identified as a novel endogenous vasodilator and neuromodulator due to its antioxidation capacity. However, whether H2S pretreatment in neonatal mouse cardiomyocytes is a protection effect against oxidative s...
Hydrogen sulfide (H(2)S) is one of three endogenous gases, along with carbon monoxide (CO) and nitric oxide (NO), that exert a variety of important vascular actions in vivo. Although it has been demonstrated that CO or NO can trigger the development of a preconditioned phenotype in postischemic tissues, it is unclear whether H(2)S may also induce protection in organs subsequently exposed to isc...
Sepsis is characterized by a generalized inflammatory response and organ failure, associated with mitochondrial dysfunction. Hydrogen sulfide donor NaHS has anti-inflammatory properties, is able to reduce metabolism and can preserve mitochondrial morphology and function. Rats were challenged with live Streptococcus pneumonia or saline and infused with NaHS (36 µmol/kg/h) or vehicle. Lung and ki...
The effects of sodium hydrosulfide (NaHS), the donor of hydrogen sulfide (H2S), on the exo/endocytosis cycle of synaptic vesicles in the motor nerve ending of the mouse diaphragm were studied using intracellular microelectrode technique and fluorescent microscopy. NaHS increased the frequency of miniature end plate potentials (MEPPs), without changing their amplitude–time parameters. NaHS also ...
Hydrogen sulfide (H(2)S) is a gasotransmitter that regulates cardiovascular functions. The present study aimed to examine the hypothesis that chronic treatment with sodium hydrosulfide (NaHS, an H(2)S donor) is able to prevent left-ventricular remodeling in spontaneously hypertensive rats (SHR). Four-week-old SHR were treated with NaHS (10, 30, and 90 micromol x kg(-1) x day(-1)), a combination...
Impaired angiogenesis and its induced refractory wound lesions are common complications of diabetes. Hydrogen sulfide (H2S) has been reported to have proangiogenic effects. We hypothesize that H2S improves diabetic wound healing by restoring endothelial progenitor cell (EPC) function in type 2 diabetes. db/db Mice were treated with sodium hydrosulfide (NaHS), 4-hydro-xythiobenzamide group (HTB)...
Introduction: The incidence rate of gastric erosions and ulcers in diabetic patients are higher due to failure of mucosal antioxidant defense and maintain enough blood flow. The present study evaluated the gastro-protective effect of sodium hydrosulfide (NaHS) against indomethacin-induced gastric lesions in diabetic rats. Methods: In order to test anti-ulcer activity of NaHS against indomet...
cells (HUVECs). Methods and Results—ApoE / mice were treated with sodium hydrosulfide (NaHS) or DL-propargylglycine (PPG); HUVECs were pretreated with NaHS. Compared with control mice, apoE / mice showed decreased plasma H2S level and aortic H2S production but increased plasma ICAM-1 and aortic ICAM-1 protein and mRNA. Compared with apoE / mice, apoE / NaHS mice showed increased plasma H2S leve...
INTRODUCTION Hydrogen sulfide (H2S) has been shown to improve survival in rodent models of lethal hemorrhage. Conversely, other authors have reported that inhibition of endogenous H2S production improves hemodynamics and reduces organ injury after hemorrhagic shock. Since all of these data originate from unresuscitated models and/or the use of a pre-treatment design, we therefore tested the hyp...
