OBJECTIVE To examine the contribution of nerve-axon reflex-related vasodilation to total acetylcholine-induced vasodilation in the skin of normal and diabetic subjects. RESEARCH DESIGN AND METHODS The skin microcirculation was evaluated at the forearm level in 69 healthy subjects and 42 nonneuropathic diabetic patients and at the foot level in 27 healthy subjects and 101 diabetic patients (33...
BACKGROUND Bone microvascular remodeling is the primary predictor of bone structure and function. Remodeling by its very nature implies synthesis and degradation of the extracellular matrix. Normally, 50% of total protein in the vessel wall is elastin. During remodeling, elastin is degraded by specialized matrix metalloproteinases (MMPs). Because the turnover of elastin is 1000-fold slower than...
The infusion of sodium nitroprusside during surgical operations produced plasma levels of cyanide of up to four times the control value. Plasma thiocyanate showed little change except during prolonged infusion of the drug, but total plasma B(12) tended to fall, as did methylcobalamin. Other cobalamins showed little change after nitroprusside infusion for short periods. During longer infusions t...
The objective of the study was to investigate the effect of exogenous nitric oxide on cellular response and production of secondary metabolites in Catharanthus roseus callus. The Cell suspension and callus of C. roseus were treated with sodium nitroprusside, then cell viability, morphology, the amount of H2O2, proline, lipid peroxidation, the activity of superoxide dismutase, catalase and perox...
The Effect of Nucleus Tractus Solitarius Nitric Oxidergic Neurons on Blood Pressure in Diabetic Rats
It has been shown that nitric oxide is synthesized in the central nervous system as well as in vascular endothelial cells. Recently, it was reported that nitric oxide was involved in central cardiovascular regulation, baroreflex modulation, and involved in a reciprocal release with excitatory amino acids in the nucleus tractus solitarii of rats. The purpose of the present study was to investiga...
Abstract: Sunflower (Helianthus annuus L.) is a relevant oilseed species used as feed in human and animal nutrition multiple industrial applications. However, oilseeds need to deal with the loss of vigor when propagule, due seed physiological quality (viability vigor) caused by deterioration events. We have evaluated present study effects seeds priming techniques (water, ascorbic acid, sodium n...
Trimetaphan nitroprusside (TNP) is a new potent hypotensive agent developed to induce and maintain decreases in arterial pressure unaccompanied by resistance. This study investigated its properties and compared them with those of sodium nitroprusside (SNP) in anaesthetized greyhounds. The mean dose response to TNP was obtained by measuring haemodynamic changes in five dogs. With increasing dose...
