Enhancement of methacholine-stimulated guanosine 3':5'-cyclic monophosphate formation in supersensitive guinea pig vasa deferentia.

Decentralization of the guinea pig vas deferens resulted in supersensitivity of the contractile response to methacholine. Methacholine also elevated cyclic GMP to a greater extent in the decentralized vas deferens than in sham-operated controls. Decentralization did not alter basal cyclic AMP or cyclic GMP content. These observations are analogous to the enhanced responsiveness of cyclic AMP formation in supersensitive beta adrenergic systems.
