This study evaluated the vasorelaxant properties of the crude hydroalcoholic extract (CE) of Cuphea carthagenensis, as well as its butanolic (BF) and ethyl acetate (EA) fractions, in rings of rat thoracic aorta. In endothelium-intact rings contracted with phenylephrine (30-100 nM), cumulative additions of increasing concentrations of CE, BF, and EA of C.(More)
The aim of this study was to assess contrast sensitivity for angular frequency stimuli as well as for sine-wave gratings in adults under the effect of acute ingestion of alcohol. We measured the contrast sensitivity function (CSF) for gratings of 0.25, 1.25, 2.5, 4, 10, and 20 cycles per degree of visual angle (cpd) as well as for angular frequency stimuli(More)
