Gamma amino outyric acid is a major
inhibitory neurotrarsr titter in the central nervous
system. In the preset study sv, Have investigate(' the
alteration of GABA receptor, In t he hrain stem of rats
during pancreatic regeneration. Three groups of rats
were used for the study: sham operated, 72 It and
7 days partially pancreatectonnsea. GABA was (juan-
(ified by [H]GABA receptor iispiacement method.
GABA receptor kin: 10, pat at i et•ers were studied by
using the binding of F'.](iAhA as ligand to the Triton
X-100 treated me,i1,;-:mes a1,J displacement with
unlabelled GABA. GhRA,v receptor activity was
studied by using the [` -1 h3cuculline and displacement
with unlabellecV euculline. ;.\13A content significantly
