Identification of prostaglandins in prevertebral venous blood after preganglionic stimulation of the cat superior cervical ganglion

Stereological Study on the Neurons of Superior Cervical Sympathetic Ganglion in Diabetic Rats

Background: Most research on autonomic dysfunction of diabetes mellitus is conducted on ganglions innervating gastrointestinal (GI) tract and there are limited works focusing on cervical sympathetic ganglia. The effects of diabetes mellitus (DM) on the neurons of superior cervical sympathetic ganglion (SCSG) are investigated by stereological methods. Material and Methods: Female rats (n=72) ran...

Development of the rat superior cervical ganglion: ingrowth of preganglionic axons.

The growth of sympathetic preganglionic axons has been studied in the fetal rat. Preganglionic axons first emerge from the spinal cord and enter the paravertebral chain of ganglia between days 12 and 13 of gestation (E12 to E13). By E14, hundreds of preganglionic neurons have sent axons into the sympathetic chain. Even at this age, the arrangement of the preganglionic axons conforms to the adul...

Effects of Prostaglandins on Cyclic AMP Content of Superior Cervical Ganglia of the Cow and Cat

Electron microscope localization of acetylcholinesterase and butyrylcholinesterase in the superior cervical ganglion of the cat. I. Normal ganglion

The distributions of acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) in the superior cervical ganglion (SCG) of the cat were determined by electron microscopy (EM) with the bis-(thioacetoxy)aurate (I), or Au(TA)2, method. Before the infusion of fixative, one of the enzymes was selectively, irreversibly inactivated in vivo, as confirmed by light microscope (LM) examination of secti...

Electron microscope localization of acetylcholinesterase and butyrylcholinesterase in the superior cervical ganglion of the cat. II. Preganglionically denervated ganglion

Cat superior cervical ganglia (SCG), denervated preganglionically 6-8 d previously, were stained for acetylcholinesterase (AChE) and butyrylcholinesterase (BuChE) by the bis-(thioacetoxy)aurate (I), or Au(TA)2, method and compared by electron microscopy with normal SCG described previously (Davis, R., and G. B. Koelle. 1978. J. Cell Biol. 78:785-809). In confirmation of earlier light microscopi...
