Abstract

The GABAergic innervation of the frog stomach was studied by means of an indirect immunohistochemical method. Whole mount preparations were obtained from frog stomachs after the animals had been perfused with a mixture of picric acid, glutaraldehyde and glacial acetic acid. Samples were incubated with an antiserum specific for GABA coupled to BSA with glutaraldehyde. Anti-rabbit IgG-HRP was processed by the two step method (Eckert and Ude 1983). GABA-positive varicose fibers and also nerve cell bodies were revealed within the myenteric plexus. The density of GABA-immunoreactive neurons was not higher than 4-8 cell/cm2, which is approximately 1% of the total nerve cell number in the myenteric plexus.
