Anatomical and functional connections of neurons of the rostral medullary raphe of the rabbit 总被引:1,自引:0,他引:1

Single cell recordings were made from neurons in the rostral medullary raphe (RMR) of the rabbit. The recording sites were ones that had been shown to yield pressor responses from electrical stimulation and by pressure injections of glutamate. Electrical stimulation of the intermediolateral (IML) region of the spinal cord led to antidromic activation of 12 of the 100 cells studied. Eleven of these cells were located in raphe pallidus or raphe magnus, and one cell was located in raphe obscurus. These findings were consistent with the results of horseradish peroxidase (HRP) histochemistry experiments. Injections of HRP into the IML led to heavy cell body labeling in raphe pallidus and raphe magnus, but sparse labeling in raphe obscurus. Cells in the RMR could be orthodromically activated by electrical stimulation of the putative defense area of the periaqueductal (PAG) but not by stimulation of putative defense areas in the hypothalamus. Most of these cells were located in raphe pallidus or raphe magnus. Similarly, HRP injections into raphe pallidus and raphe magnus led to heavy cell body labeling in the PAG but not the hypothalamus; no cell body labeling was found in the PAG when injections were made into raphe obscurus. 相似文献

A case of acute perforation of the terminal ileum induced by avulsion of the bowel wall in a segment of acutely inflamed Crohn's disease is presented. This case is unusual in that the avulsion developed after delivery following the rapid retraction of the uterus which had been compressing a small localized perforation and abscess. A review of the literature has failed to demonstrate a similar case report. 相似文献
