In view of the role of serotonin in adrenocortical regulation, the effects of depletion of hypothalamic serotonin, using localized injections of the neurotoxin 5,7-dihydroxytryptamine into the hypothalamic paraventricular nucleus, on the rise in plasma corticosterone following afferent neural stimulation, were studied.

Annals of the New York Academy of Sciences, 1977
Hypophysectomy leads to a small increase in tyrosine hydroxylase activity of all brain areas containing noradrenergic neurons or tuberoinfundibular dopamine neurons, but nigroneostriatal dopamine neurons are not so affected. ACTH or corticosterone treatment inhibited this effect of hypophysectomy in some noradrenergic neurons and in tuberoinfundibular ...

American Journal of Hypertension, 1990
Studies were made on whether oral or intraventricular (icv) NaCl had different effects on the blood pressure (BP) of Dahl rats. Five groups of each strain of Dahl rats, salt-sensitive (S) and salt-resistant (R) rats, were given, respectively, a diet containing 0.3% and icv infusion of 0.15 mol/L NaCl (group 1, control group) or 0.8 mol/L NaCl (group 2),

Journal of the Autonomic Nervous System, 1991
Corticotropin-releasing factor (CRF) modifies cardiovascular function and hemodynamic status after administration into the central nervous system and into the peripheral circulation. The mechanisms by which CRF alters arterial pressure and heart rate have been examined in detail whereas little information exists regarding the processes mediating CRF ...

Neuropharmacology, 1987
Chronic administration of desipramine resulted in a significant decrease in the degree of stimulation of production of cyclic AMP by noradrenaline, isoproterenol and forskolin in slices of the cerebral cortex of the rat. In preparations of membranes from similarly treated animals, GppNHp- and forskolin-stimulated adenylate cyclase activity was ...

Alcohol, 1987
In an earlier study ethanol drinking was induced by reducing mice to 80% of their free-feeding weight and feeding them their daily food allotment prior to the experimental session. The mice were given an ascending series of ethanol concentrations (1 to 8%).

Pharmacology Biochemistry and Behavior, 1995
Previously, we reported that administration of the 5-HT2A/C receptor agonist, DOI [(+/-)-1-(2,5-Dimethoxy-4-iodophenyl)-2-aminopropane], can simultaneously produce the head-twitch response (HTR) and the ear-scratch response (ESR) in mice. Our recent studies have indicated that the HTR is a 5-HT2A receptor-mediated phenomenon, whereas the ESR is ...

The effect of gold thioglucose (GTG) administration on neurons containing feeding-related peptides in the hypothalamic arcuate nucleus was examined in mice. Intraperitoneal GTG injection increased the body weight and produced a hypothalamic lesion that extended from the ventral part of the ventromedial nucleus to the dorsal part of the arcuate nucleus.
