Does pregnancy alter adrenergic mechanisms in uterine arterioles of rats?
Both alpha- and beta-adrenergic responses are important mechanisms for the regulation of uteroplacental perfusion. By use of an in vitromicrovascular technique, we have shown pregnancy-associated alteration in adrenergic responses in the uterine microcirculation of the rat.
Among treatment-seeking alcoholics, early age at onset is generally associated with a more severe course of alcoholism and lower cerebrospinal fluid 5-hydroxyindoleacetic acid concentration.
