Normal action of the female ovulatory cycle is dependent on a surge of luteinizing hormone (LH) from the pituitary. Regulation of the levels of LH is therefore vital to reproductive function. It has long been established that gonadotropin-releasing h

The present study was designed to investigate how repeated injections of oxytocin influence plasma levels of vagally controlled hormones such as gastrin, cholecystokinin (CCK), insulin and somatostatin, as well as of endogenous oxytocin and glucose.

Aging is associated with a disturbance in the regulation of the hypothalamic-pituitary-adrenal axis (HPA) and reduced levels of glucocorticoid receptors (GR) in the hippocampus. To compensate for these effects, we have investigated whether estrogen t

We have hypothesized that the midbrain dopamine (DA) neurons are a target for insulin action in the central nervous system (CNS). In support of this hypothesis, we have previously demonstrated that direct intracerebroventricular infusion of insulin r

The ability of the intracerebroventricular (icv) injection of interleukin-1 beta (IL-1 beta) to alter plasma prolactin (PRL) levels in rats remains controversial, with reports of increases, decreases, or no changes in secretory rate. These discordant

The occurrence, cellular distribution and nature of the 27-amino acid form of pituitary adenylate cyclase-activating peptide (PACAP-27) in the adrenal glands of mammals was investigated by means of immunohistochemistry, radioimmunoassay and chromatog

The possible involvement of opioid receptors in mediating the inhibitory effects of immobilization stress on testicular steroidogenesis was determined in adult male rats. Unstressed controls and animals exposed to 3 h of immobilization stress were in

In this investigation we have studied the uptake of gamma aminobutyric acid (GABA) into anterior pituitary slices. Tissue:medium ratios of about 45:1 were obtained after a 30-min incubation. The process responsible for 3H-GABA uptake was temperature-

Synaptic plasma membranes from the brain are known to have specific binding sites for several steroid hormones, but the mechanism of membrane transduction of steroid signals is not understood. In this study, corticosterone was found to stimulate 45Ca

The purpose of the present study was to examine the effects of galanin on the basal and stimulated activity of tuberoinfundibular dopaminergic (TIDA) neurons in male and female rats. TIDA neuronal activity was estimated by measuring dopamine (DA) syn
