Hydrogen sulfide and endothelium-dependent vasorelaxation.
In addition to nitric oxide and carbon monoxide, hydrogen sulfide (H2S), synthesized enzymatically from l-cysteine or l-homocysteine, is the third gasotransmitter in mammals. Endogenous H2S is involved in the regulation of many physiological processes, including vascular tone. Although initially it was suggested that in the vascular wall H2S is synthesized only by smooth muscle cells and relaxe...
متن کاملImpairment of endothelium-dependent vasorelaxation in experimental atherosclerosis is dependent on gender.
OBJECTIVE Nitric oxide (NO) has been suggested to have antiatherosclerotic effects. It has also been demonstrated that there is a greater basal release of endothelium derived relaxing factor (EDRF) in female as compared to male rabbit aorta, which also might have beneficial effects in atherosclerosis. We thus sought to determine if gender influences the severity of atherosclerosis. METHODS We...
متن کاملAcyl Chain-Dependent Effect of Lysophosphatidylcholine on Endothelium-Dependent Vasorelaxation
Previously we identified palmitoyl-, oleoyl-, linoleoyl-, and arachidonoyl-lysophosphatidylcholine (LPC 16:0, 18:1, 18:2 and 20:4) as the most prominent LPC species generated by endothelial lipase (EL). In the present study, we examined the impact of those LPC on acetylcholine (ACh)- induced vascular relaxation. All tested LPC attenuated ACh-induced relaxation, measured ex vivo, using mouse aor...
متن کاملEndothelium-dependent vasodilatation in forearm is impaired in stroke patients.
OBJECTIVES To investigate endothelium-dependent vasodilatation (EDV) in stroke patients. DESIGN Cross-sectional. SETTING University referral hospital. SUBJECTS We studied 23 stroke patients (65-75 years old) who did not have atrial fibrillation or Warfarin treatment. Forty-six age- and sex-matched healthy controls and another 32 controls matched also for hypertension and medication were u...
متن کاملPhysical conditioning can modulate endothelium-dependent vasorelaxation in rabbits.
To investigate whether exercise training can modulate endothelium-dependent vasorelaxation, male New Zealand White rabbits were divided into either control or training groups. The training animals were trained on a treadmill with a running speed of 0.88 km/hr on a 0 degree grade for 10-60 minutes/day, 5 days/week for 8 weeks. After exercise training, the resting heart rate was lowered (p < 0.05...
