Urinary kallikrein was measured in rats bred to be susceptible (S) or resistant (R) to the hypertensive effect of salt. To determine kallikrein, three different methods were used: (1) a new direct radioimmunoassay (RIA) for the enzymic protein: (2) a method based on the capability of kallikrein, when incubated with kininogen, to generate kinins which were then measured by RIA (kininogenase acti...
Objective(s): Nitric oxide (NO) is an important neurotransmitter in central nervous system involved in central cardiovascular regulation. The presence of NO in the pedunculopontine tegmental (PPT) nucleus has been shown, but its cardiovascular effect has not been determined. In the present study, the cardiovascular effect of NO in the PPT nucleus was evaluated. Materials and Methods: After indu...
BACKGROUND Elevated plasma homocysteine concentrations in renal patients are associated with accelerated cardiovascular disease. The mechanism(s) by which homocysteine acts remains unclear however, evidence implicates a role involving endothelial dysfunction. METHODS Rat femoral arteries after acute or 4-h pre-incubation with racemic D,L-homocysteine (100 microM) were mounted on a myograph, p...
The use of exogenous compounds such as ‘gasotransmitter’ molecules is a well-established agronomic strategy to improve the crop tolerance environmental stresses. In this current work, when Cr (200 µM) was combined with nitric oxide (NO) generator sodium nitroprusside SNP, 500 there suppression metal-induced alterations in embryo growth. Exogenous NO produced by SNP reduced accumulation toxic hy...
Dexamethasone suppresses eNOS and CAT-1 and induces oxidative stress in mouse resistance arterioles.
Long-term treatment with glucocorticoids is associated with mild to moderate hypertension. We reported previously that downregulation of endothelial NO synthase (eNOS) expression and activity is likely to contribute to this increase in blood pressure. In the present study, we tested the effects of dexamethasone on the vasodilation of microvascular arterioles using implanted dorsal skin-fold cha...
Cessation of blood flow during ischemia will decrease both distending and shear forces exerted on endothelium and may worsen ischemic lung injury by decreasing production of nitric oxide (NO), which influences vascular barrier function. We hypothesized that increased intravascular pressure (Piv) during ventilated ischemia might maintain NO production by increasing endothelial stretch or shear f...
In order to evaluate the potential of citogate and turnip vegetable oil in increasing the performance of barnyardgrass (Echinochloa crus-galli) control by colthodim and haloxyfop-r-methyl ester herbicides, two greenhouse experiments were carried out in the Research Greenhouse of the Faculty of Agriculture, Birjand, Iran, in 2016; this study was based on a factorial arrangement as a completely r...
a field experiment was conducted to evaluate the effect of varying doses of haloxifhope-r-methyl ester herbicide on grass weeds grown at various stages in 2011-2012 growing season in research farm of college of agriculture, shiraz university. the study was carried out as split split plot based on randomized complete block design with three replicates. treatments were haloxifhope-r-methyl ester ...
BACKGROUND AND AIMS Periodontitis is a chronic inflammation that involves nitro-oxidative stress with damaging periodontal structural effects. We aimed to evaluate the consequences of low-dose cimetidine on nitro-oxidative stress in periodontitis. METHODS A rat model of ligature-induced periodontitis was used. After two weeks, the periodontitis groups were treated with cimetidine, aminoguanid...
Damage to the leech or mammalian CNS increases nitric oxide (NO) production and causes accumulation of phagocytic microglial cells at the injury site. The aim of this study was to determine whether NO plays a role in microglial migration and accumulation at lesions in which NO is generated by a rapidly appearing endothelial nitric oxide synthase (eNOS) in leeches. Immunohistochemistry and cytoc...
