Abstract：
:gamma-Aminobutyric acid (GABA) and glutamic acid decarboxylase (GAD) activities were measured in the ovary and the Fallopian tube of rats and compared with brain values. GABA levels in the Fallopian tube were about twice as high as in the brain, while in the ovary they represented only about 5% of the amino acid content of the CNS. In vitro decarboxylation of glutamate, measured via CO2 formation, occurred both in the Fallopian tube and in the ovary. These two organs contained, respectively, 10% and 1% of brain GAD activity. However, the actual formation of GABA from glutamate in a high-speed supernatant was detectable only in the Fallopian tube, where it represented about 5% of brain GAD activity. In contrast with the enzyme present in ovary, liver, anterior pituitary, and kidney, that in the Fallopian tube was quantitatively precipitated by a specific antiserum directed against rat neuronal GAD. Moreover, subcutaneous transplantation resulted in a quantitative decrease of both GABA levels and GAD activity in the Fallopian tube while no change occurred in the ovary, and vagus nerve section induced a 50% decrease of GAD activity in the Fallopian tube, although GABA levels were not significantly altered. The findings suggest an extrinsic GABAergic innervation in the rat Fallopian tube but not in the ovary.
