objective(s): endometriosis is a complex gynecologic disease with unknown etiology. noscapine has been introduced as a cancer cell suppressor. endometriosis was considered as a cancer like disorder, the aim of present study was to investigate noscapine apoptotic effect on human endometriotic epithelial and stromal cells in vitro. materials and methods:in this in vitro study, endometrial biopsie...

Nitrogen dioxide is formed during delivery of inhaled nitric oxide for the treatment of patients with pulmonary hypertension. Soda lime has been shown to absorb nitrogen dioxide. We tested three different commercially available soda lime preparations (Sodasorb, Drägersorb 800 and Sofnolime) for their efficacy in absorbing nitrogen dioxide and nitric oxide during simulated nitric oxide inhalatio...

There is indirect, contradictory evidence both for increased and reduced synthesis of the endothelium-derived vasodilator, nitric oxide, in the pulmonary circulation during acute hypoxia. Therefore, we decided to directly measure the effect of acute hypoxia on nitric oxide production by cultured pulmonary endothelium. Because increases in the intracellular free calcium concentration are known t...

We investigated the effects of anaesthesia on dynamic nitric oxide production, concentrations of tetrahydrobiopterin and the accumulation of cyclic GMP (cGMP) in the rat central nervous system (CNS). Rats were assigned to anaesthesia with halothane, isoflurane, pentobarbital, diazepam, ketamine or xenon (n=6 per group). After 30 min, [14C]L-arginine (i.v.) was given and, after a further 60 min ...

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...

The susceptibility of Brugia malayi microfilariae and adults to injury by the murine macrophage cell line J774 activated with gamma interferon and bacterial lipopolysaccharide has been examined in vitro. Parasites of both stages showed a decline in viability over 48 h of coculture with activated macrophages, assessed by their capacity to reduce the tetrazolium salt 3-[4,5-diethylthiazol-2-yl]-2...

1. The role of nitric oxide as mediator of the vascular alterations present in different models of experimental liver cirrhosis is controversial. In the present study, we evaluated the role of nitric oxide and that of the endothelium in the response to phenylephrine and acetylcholine of isolated aortic rings from chronic bile duct-ligated (29 days) rats and their corresponding controls. Experim...

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...
