The innervation of Rana ridibunda stomach has been studied by the following methods: demonstration of cholinesterase activity; FIF method for catecholamines; immunohistochemistry for VIP; SP and SOM and conventional electron microscopy. The cholinergic innervation is important in the stomach wall where in addition to the intrinsic plexuses there is an(More)
The innervation of Rana ridibunda esophagus myenteric plexuses has been studied by the following methods: demonstration of cholinesterase activity; FIF method for catecholamines; immunohistochemistry for VIP, SP and SOM, and conventional electron microscopy. The cholinergic innervation is important in the esophagus wall where, in addition to the well known(More)
1. The innervation of Rana ridibunda intestine has been studied by the following methods: (a) demonstration of cholinesterase activity; (b) FIF method for catecholamines; (c) immunohistochemistry for VIP, SP and SOM, and (d) conventional electron microscopy. 2. The intrinsic intestinal innervation is represented by cholinergic-, VIPergic-, SP- and SOM-like(More)
The innervation of the diaphragm has been studied by three methods--cobalt tracing of the nerves, demonstration of cholinesterase activity and fluorescence microscopy for catecholamines and VIP. The cobalt method reveals the peripheral nerve fibers with a sharpness similar to that shown at the level of the central nervous system where this method has so far(More)
Human neuroblastoma cells growing in culture offer a unique oppor tunity to study proliferating human cells with a neuronal phenotype. We have previously identified several neuroblastoma cell lines which show spontaneous conversion (N/S interconversion) between two morphologi cally distinct cell types: neuroblastic (N-type) cells and variant,(More)
