Somatopetal transport of horseradish peroxidase (HRP) in the peripheral and central branches of dorsal root ganglion cells.

The axonal transport of HRP in both the peripheral and central branches of dorsal root ganglion cells was studied in rats. For studying axonal transport in the peripheral branch HRP as a dry substance was applied to the peroneal nerve injured either by teasing, by cutting or crushing. After a short survival time (22 h) mainly small spinal ganglion cells of the corresponding segments were labelled, while after a prolonged survival time (70 h) mainly large cells were labelled. These labelling differences are referred to different transport rates or to differences in the process of accumulation of HRP in neurons of various sizes. No evidence could be found for HRP transport from the peripheral into the central branch. Injection of HRP into the spinal cord (survival time 22 h) or into the dorsal column nuclei (survival time 46 h) was followed by labelling of numerous spinal ganglion cell perikarya of all sizes. Reaction product was found also within the prebifurcation segment of spinal ganglion cell processes. On the basis of light microscopic exploration only somatopetal transport could be detected.

[To day's biliary surgery (author's transl)].

Cholelithiasis is on the increase and operative indications are of a wider range including even preventive procedures. Surgery for silent stones, intra-operative cholangiography, indications for papillosphincterotomy and anastomoses, as well new procedures for nonoperative removal of residual stones are discussed. Transhepatic drainage for some reiterative stenoses of high anastomoses is recommended.
