Xylazine causes a dose-related loss of the righting reflex (LRR) in mice when combined with a subanesthetic dose of chloral hydrate. Compounds that preferentially block alpha 2-adrenoceptors antagonize this xylazine plus chloral hydrate LRR at low do

Thyrotropin-releasing hormone (TRH) and a structurally related analogue of TRH, MK-771, administered IP or orally, restored flex or reflex activity in rats with acute spinal transections. The effect of MK-771 in this test was not modified by pretreat

Iontophoretically applied muscimol exerted a potent inhibitory action on the firing of spontaneously active cerebral cortical neurons of rats. On the basis of ejection currents employed, muscimol was considerably more potent than γ-aminobutyric acid

Comparisons among spontaneously hypertensive (SHR), Kyoto Wistar (KW), and Wistar (W) rats were made of the functional states of central nervous system (CNS) α2-adrenoceptors (clonidine-induced mydriasis) and nonvascular peripheral presynaptic α2-a

Topically applied MK-771 (pyro-2-aminoadipyl-histidyl-thiazolidine-4-carboxamide), a novel thyrotropin-releasing hormone (TRH) analog, was found to be equipotent with TRH in depolarizing the ventral roots of the isolated, hemisected amphibian (Bufo m
