Intrafascicular decompression in the treatment of causalgia with special reference to the mechanism.

A new concept of the pathogenesis of causalgia is suggested in accordance with experimental and clinical work. Endoneural hypertension secondary to nerve trunk disruption is incriminated and intrafascicular decompression is used as the key therapeutic measure. In 14 patients with causalgia thus treated, all except 1 were cured. No symptomatic recurrence was noted in a 4- to 6-year follow-up study.

Studies on mechanism of action of luteinizing releasing hormone (LH-RH) in ovulation of fish--intracellular distribution of LH-RH-A in pituitary gonadotrophs as revealed by electron-microscopic autoradiography.

The results of competitive bending experiment and the electron-microscopic autoradiographic studies show that the peptide hormone, LH-RH-A (a nonapeptide), could be internalized into the gonadotrophs of the pituitary gland of the mud-carp (Cirrhrinus molitorella). It is demonstrated that the labeled peptide, 125I-LH-RH-A, is internalized not only into the cytoplasm, but also into the nucleus, apparently via the nuclear pores. It is, therefore, suggested that the peptide hormone might act directly on the genome either in the form of a hormone-receptor complex or of a single molecule.
