An analytical technique is described which permits the quantitation of picogram concentrations of 3-methoxy-4-hydroxyphenylethylene-glycol (MHPG) in acid hydrolyzed extracts of microdissected regions of the rat brain, and this procedure is used to determine if alterations in the activity of noradrenergic neurons are reflected by changes in the(More)
Chronic administration of 2,4-dithiobiuret (DTB), causes delayed-onset neuromuscular weakness in rats. This effect results from inhibition of quantal release of acetylcholine (ACh) from motor nerve terminals. The effects of noncholinergic neurotransmission are unknown. The purpose of the present study was to examine the presynaptic mechanisms involved in(More)
Benign prostatic hyperplasia (BPH), common in aging males, is often treated with alpha(1)-adrenoceptor antagonists. To minimize hypotensive and other side effects, compounds with selective antagonist activity at alpha(1A)- and alpha(1D)- (compared with alpha(1B)-) adrenoceptors were evaluated that would block lower urinary tract alpha(1)-adrenoceptors in(More)
