Effects of bicuculline on inspiratory activities in piglets.

abstract：:The role of polyamines in the regulation of free intrasynaptosomal Ca2+, [Ca2+]i was studied. After preincubation of rat brain synaptosomes with 5 mM difluormethylornithine (DFMO), an irreversible inhibitor of ornithine decarboxylase, the K+-induced increase of [Ca2+]i was 33% less than that in non-treated synaptosome...
