Nitric oxide and superoxide are free radicals that appear to contribute to the pathogenesis of a number of brain disorders, and cerebral endothelial cells are a potential target of these agents. Because of the capacity for these two agents to combine, it has been suggested that nitric oxide might either enhance or inhibit the toxic effects of superoxide. To establish the effect of the generatio...
To elucidate the molecular mechanism of the vascular action of atrial natriuretic factor (ANF), we investigated the effects of synthetic ANF and sodium nitroprusside on the levels of intracellular cyclic nucleotides and prostacyclin (measured as its stable metabolite 6-keto-prostaglandin F1 alpha) in cultured vascular smooth muscle cells from rat mesenteric artery and, in some experiments, from...
Nitric oxide (NO) has signaling property in plants, therefore the effect of nitroprusside (SNP) as an NO producing agent on viability in the cell culture, lipid peroxidation and activity of superoxide dismutase, catalase and peroxidase in the callus of Catharantus roseus was investigated. Cell suspension was prepared from callus of Catharantus roseus, and the cells were treated with 0, 10, 50, ...
Forearm endothelium-dependent vasodilation is impaired with age in sedentary, but not endurance-trained, men. The purpose of this investigation was to determine whether these age- and physical activity-related differences in endothelium-dependent vasodilation also occur in the leg. Brachial and common femoral arterial blood flow were measured with Doppler ultrasound during increasing doses of a...
Sweet violet (Viola odorata) is a perennial herbaceous plant with ornamental and medicinal properties. The purpose of this study was to investigate the effect of different levels of water-deficit and spraying with salicylic acid, sodium nitroprusside and zinc Nano-oxide on physiological parameters, secondary metabolites and enzymatic activity of sweet violet. Factorial experiment in completely ...
The effect of sodium nitroprusside on the relationship between left ventricular pressure and volume during diastole was studied in 11 patients with congestive heart failure. Nitroprusside was infused to lower mean arterial pressure approximately 20-30 mm Hg. High fidelity left ventricular pressures were recorded in all patients simultaneously with left ventricular cineangiography (biplane in ei...
