Objective To observe the analgesic effect of early hyperbaric oxygen (HBO) treatment in chronic constriction injury (CCI) rats, and to analyze the influence of HBO on the expression of neuronal nitric oxide synthase and inducible nitric oxide synthase and on the levels of inflammatory factors. Methods Rats were assigned into three groups randomly: sham, CCI, and HBO groups. The CCI rat model wa...
background: the blocking of nitric oxide synthase (nos) activity may reason vasoconstriction with formation of reactive oxygen species. propolis has biological and pharmacological properties, such as antioxidant. the aim of this study was to examine the antioxidant effects of propolis which natural product on biochemical parameters in brain and lung tissues of acute nitric oxide synthase inhibi...
Nitric oxide (NO), a biological mediator involved in vascular physiology, was sensed electrochemically using a microelectrode array. Angiogenin was shown to trigger nitric oxide synthase (NOS) activity in human umbilical vein endothelial cells and embryonic stem cell derived endothelial cells independently from its RNase activity.
Neuronal nitric oxide synthase is critically involved in the pathogenesis of acute lung injury resulting from combined burn and smoke inhalation injury. We hypothesized that 7-nitroindazole, a selective neuronal nitric oxide synthase inhibitor, blocks central molecular mechanisms involved in the pathophysiology of this double-hit insult. Twenty-five adult ewes were surgically prepared and rando...
Recent studies have indicated that nitric oxide may play a role in inhalation anaesthesia. Inhibition of nitric oxide synthase reduces the minimum alveolar concentration (MAC) for inhalation anaesthetics and decreases cerebellar nitric oxide synthase (NOS) activity in rats. In this study, we have explored further the role of nitric oxide in isoflurane anaesthesia by examining the effects of a n...
BACKGROUND Previous work has suggested that in the liver, adenosine preconditioning is mediated by nitric oxide. Whether the endothelial isoform of nitric oxide synthase plays a part in this mechanism has however not yet been investigated. METHODS Wistar rats were used (6 in each group)--Groups: (1) sham, (2) ischemia-reperfusion, (3) adenosine + ischemia-reperfusion, (4) endothelial isoform ...
