Effect of gamma-aminobutyric acid on growth hormone and prolactin secretion in man: influence of pimozide and domperidone. Cavagnini F, Benetti G, Invitti C, Ramella G, Pinto M, Lazza M, Dubini A, Marelli A, Müller EE.
Parallel changes in PRL and GAD activity were observed in acutely treated animals. Conversely, a return to normal of the GAD activity associated with high plasma PRL levels was induced by chronic haloperidol and sulpiride treatment. Results are discussed in the light of the possible existence of a hypothetical PRL-gamma-aminobutyric acid.
To find out whether the gamma-aminobutyric acid (GABA)ergic system affects PRL secretion in humans, sodium valproate (DPA or Na-dipropyl-acetate), a drug inducing increase of endogenous GABA, was administered to 20 normal and 15 hyperprolactinemic subjects. PRL circulating levels were measured by RIA in the samples obtained after acute oral treatment with 400 mg DPA. A significant decrease (P less than 0.
The effect of Gamma-Aminobutyric Acid (GABA) on the release of Prolactin (PRL), Luteinizing Hormone (LH), and Follicle Stimulating Hormone (FSH) in spayed rats was studied. Adult female rats of the Wistar strain were ovariectomized 30 days prior to the experiments and various doses of GABA and/or picrotoxin (PCT) were injected into the third ventricle under Nembutal anesthesia. A dose of 10-8 mole GABA produced a marked decrease in plasma PRL levels.
A single oral dose of 5 g gamma aminobutyric acid (GABA) was given to 19 subjects and serial venous blood samples were obtained before and 3 h after drug administration. A placebo was administered to 18 subjects who served as controls. GABA caused a significant elevation of plasma growth hormone levels (P < 0. 001), but did not consistently alter plasma prolactin concentration since only 5 out of 15 subjects showed an increase of the hormone.
The possible involvement of endogenous opioids in the gamma-aminobutyric acid-controlled (GABAergic) inhibition of growth hormone (GH) and prolactin (PRL) during physical exercise was evaluated in normal men. After fasting overnight, seven subjects were tested on four mornings at least 1 week apart. Exercise was performed on a bicycle ergometer. The workload was gradually increased at 3-min intervals until exhaustion and lasted about 15 min in all subjects.
