diabetes is characterized by a nitric oxide deficiency at the wound site. diabetes is a factor that influences all stages of wound healing. in animals with acute experimental diabetes induced by streptozotocin (stz), the early inflammatory responses after wounding is impaired, fibroblast and endothelial cell proliferation is reduced as well as accumulation of reparative collagen and gain in wou...

objective(s) the fractions of candida albicans have been used as an immunomodulator. the present work assessed the effect of different fractions of c. albicans on nitric oxide (no) production by mice peritoneal macrophages. materials and methods cell wall and cytoplasmic fractions of c. albicans atcc 10321 strain were extracted. mice peritoneal macrophages were purified and cultured. different ...

introduction: different vasoactive factors can modulate cardiovascular adaptation to hemorrhagic shock including nitric oxide (no). in this study we investigated the effect of  the no synthase inhibitor for treatment of  decompensated hemorrhagic shock in normotensive and hypertensive rats. methods: twenty‑four male wistar rats were divided into two groups: the normotensive and hypertensive gro...

background: a number of medicinal plants have been used to treat various immunological diseases. nitric oxide (no) has an important regulatory role in the various types of inflammatory processes. objective: to investigate the no modulatory activity of the extracts of several medicinal plants native to iran including dracocephalum kotschyi, linum persicum, dionysia termeana, salvia mirzayanii, f...

background since nitric oxide (no) has an oxidant activity, lower levels following a varicocelectomy may result in better functioning sperm, improved semen quality and consequently higher fertility rates. however, this procedure should be examined in more detail. objectives accordingly, this study was performed to compare the before and after varicocelectomy levels of no in the seminal fluid of...

the mechanism by which lead may cause a perturbotion in the nevous system is through the nitric oxide synthase. in this study the effect of lead acetate on the hippocampal constitutive nitric oxide production was studied. the variation in the nitric oxide production may contribute to physiological lead neurotoxicity in vivo. different concentrations of lead acetate (10-9 to 10-6 m), wre added t...
