[Vacuolated neurons in the superior cervical ganglion in rats after repeated stress].
In the article the authors deal with unsolved problem of the occurrence and character of vacuolated neurons (VN) in autonomic ganglia. They describe their own investigations of vacuolated neurons in the superior cervical ganglion of male rat (Wistar) after repeated stress and fixation of the tissue in glutaraldehyde/OsO4. Vacuolated neurons had a well-preserved structure of ganglion cell in spite of that in cytoplasma they contain vacuoles reaching enormous size. Vacuoles had very characteristic content. They were filled in by content of thin density. Along the membrane of the vacuole were cytoplasmatic extensions, their transverse profiles and isolated invaginations of the membrane of vacuole. From the structure of the vacuole cannot be appreciated the character of the vacuole--whether it is phagosomes or the reservoir of cell metabolite established for its function. Because the vacuolated neurons have the same structure as vacuolated neurons in autonomic pelvic ganglia of the rat, the authors in discussion dealt especially with the results of the investigation of the mentioned ganglia.
