Dentists treating craniomandibular dysfunction frequently encounter pain and dysfunction in seemingly unrelated distal areas of the body. This is a study using manual palpation to demonstrate a change in distal muscle pain response caused by altering an apparent noxious tooth contact. Forty-four (n = 44) patients with a defined muscle involvement were(More)
1. Caffeine (35-70 mM) elicited contractions of Aplysia buccal muscle El. In a Ca2+-free medium, in which ACh-elicited contractions rapidly fail, caffeine elicited contractions of approximately the same size as in normal medium. 2. 5-HT (10(-8) M and 10(-7) M) did not enhance caffeine-elicited contractions. 3. Lower concentrations (1-10 mM) of caffeine(More)
Hexamethonium bromide (Hex. Br.) blocks acetylcholine (ACh) elicited contractions but not electrically elicited contractions of isolated preparations of Aplysia californica dorsal extrinsic muscle. Serotonin (5-hydroxytryptamine, 5-HT) enhances both magnitude and relaxation rate of ACh and electrically elicited contractions. In the presence of Hex. Br.,(More)
Serotonin enhances acetylcholine-elicited contractions of buccal muscle E1 of Aplysia. To characterize the serotonin receptor, actions of ligands of specific serotonin receptor subtypes were examined. Ketanserin, an antagonist at 5-HT2 receptors, had little effect. Two 5-HT1A ligands, LY165163 and 8-OH-DPAT, mimicked the effect of serotonin, although with(More)
Metaphit, a derivative of phencyclidine (PCP) differing by the meta substitution of an isothiocyanate group on the phenyl ring, was given into the lateral cerebral ventricle of mice alone and as a pretreatment to the subsequent i.p. injection of PCP and pentobarbital. Drug effects on motor performance as an index of neurologic impairment were quantified(More)
The possible role of cyclic AMP in mediating opposite modulatory effects of serotonin (5-HT) on Aplysia buccal mass muscles E1 and E2 was examined. Serotonin enhances E1 contractions and inhibits E2 contractions. Adenylate cyclase in membranes of both E1 and E2 is stimulated approximately 180% by 10(-6) M 5-HT and 300% by 10(-3) M 5-HT.
