background: skin flap grafting is a popular approach for reconstruction of critical skin and underlying soft tissue injuries. in a previous study, we demonstrated the beneficial effects of two 5α-reductase inhibitors, azelaic acid and finasteride, on tissue survival in a rat model of skin flap grafting. in the current study, we investigated the involvement of nitric oxide and inducible nitric o...
We previously reported that angiotensin II stimulates an increase in nitric oxide production in pulmonary artery endothelial cells. The aims of this study were to determine which receptor subtype mediates the angiotensin II-dependent increase in nitric oxide production and to investigate the roles of the angiotensin type 1 and type 2 receptors in modulating angiotensin II-dependent vasoconstric...
endo-derived nitric oxide (no) is synthesized from l-arginine by endothelium nitric oxide synthase (enos). since reduced no synthesis has been implicated in the development of coronary atherosclerosis; we hypothesized that polymorphisms of nos gene might be associated with increased susceptibility to this disorder and coronary artery disease (cad). we studied the 27 base pair tandem repeat poly...
The distribution of nitric oxide synthase was investigated in human cerebral blood vessels and brain tissues. NADPH-diaphorase histochemistry, which is a marker for nitric oxide synthase in neurons and endothelial cells, revealed periadventitial nerve fibers in the arteries of the circle of Willis and their cortical branches, as well as the common carotid and subclavian arteries. The fibers wer...
nitric oxide is a short-lived mediator, which can be induced in a variety of cell types and produces many physiologic and metabolic changes in target cells. it is important in many biological functions and generated from l-arginine by the enzyme nitric oxide synthase. nitric oxide conveys a variety of messages between cells, including signals for vasorelaxation, neurotransmission and cytotoxici...
nitric oxide is an important vasorelaxant factor that it inhibits platelet adhesion and proliferation of smooth muscle cells. no is synthesized from l-arginine by means of endothelial nitric oxide synthase (enos) which is an isoform of nitric oxide synthase.in the present study, we examined possible association between the 27 base pair (bp) repeat polymorphism in intron 4 of the enos3 gene ...
various polymorphisms on endothelial nitric oxide synthase (enos) gene cause reduced production of no, the endothelial relaxing factor, and may accelerate the process of atherosclerosis. the study designed to investigate the frequency of t-786c polymorphism of the enos gene in patients suffering from coronary artery disease (cad) in north-west of iran. one hundred twenty subjects including 60 p...
background: during the initial phase of an infection, there is an upregulation of inducible nitric oxide synthase in the macrophages for the production of nitric oxide. this is followed by the recruitment of polymorphonuclear leukocytes (neutrophils) which release arginase. arginase competes with inducible nitric oxide synthase for a common substrate l-arginine. objective: to investigate whethe...
