Abstract/OtherAbstract:
Treatment of young rats with vitamin D3 plus nicotine, which has been proposed as a model of cardiovascular calcium overload, produced an increase in the calcium content of the mesenteric arterial bed and lowered in vitro vasoconstrictor responses to norepinephrine and serotonin. Attenuation of the vasoconstriction induced by norepinephrine by the endothelium-dependent vasodilators, carbachol and histamine, was diminished, but the effects of sodium nitroprusside and papaverine were unchanged. The vitamin D3 plus nicotine model may be useful for the study of the involvement of calcium overload in vascular endothelial dysfunction.
