Decrease of mast cells in W/Wv mice and their increase by bone marrow transplantation.

Production of tissue mast cells was evaluated in genetically anemic mice of W/Wv genotype and was found to be abnormal. In the skin of adult W/Wv mice the number of mast cells/cm was less than 1% of the number observed in the congeneic +/+ mice. No mast cells were detectable in other tissues of the W/Wv mice. After transplantation of bone marrow cells from +/+ mice the number of mast cells in the skin, stomach, caecum, and mesentery of the W/Wv mice increased to levels similar to those of the +/+ mice. These results show that the W/Wv mouse is a useful tool for the investigations concerning the physiologic roles and the origin of mast cells.

A probable case of Leishmaniasis (Espundia) acquired in Japan.

A case of mucocutaneous leishmaniasis is described in a Japanese patient who had never been abroad, suggesting either contact with an infected person from Brazil or the presence in Japan of indigenous cutaneous leishmaniasis. This case illustrates the value of electron microscopic examination in such infections, since it provided the definitive diagnosis.

Neuroendocrine-immune modulation may be useful for allograft-specific immunosuppression in small bowel transplantation.

PURPOSE: The authors have previously demonstrated that the neuropeptide bombesin (BBS) prevented allograft mucosal atrophy under tacrolimus (TRL) immunosuppression for rats small bowel transplantation (SBT). The present study investigated whether BBS had immunosuppressive effects on small bowel allografts. METHODS: Allogeneic SBT was performed heterotopically in rats (n = 12) that received daily administration of 0.1 mg/kg/d TRL from postoperative day 0 to day 14. Rats divided into two groups of six rats each were administered BBS or normal saline as a control. Biopsy of the allograft was performed from the stomal site on postoperative days 6, 10, and 14. The state of the graft mucosal villi was evaluated by H & E staining and TUNEL immunohistochemistry. RESULTS: By postoperative day 14, extensive mucosal destruction accompanied by heavy transmural cellular infiltration had developed in the control group. Lymphocytes and plasma cells infiltrated the lamina propria of the allograft without the distorting villous architecture in the BBS group. The TUNEL index of graft mucosa in the control group was 1.26% +/- 0.37% (mean +/- SD) and that in the BBS group, 0.59% +/- 0.20%, respectively (p < .001). CONCLUSION: This study demonstrated an immunosuppressive effect of bombesin on transplanted allografts, which might dramatically reduce the dose of TRL required for postoperative immunosuppression.

Enhancing medical student consultation request skills in an academic emergency department.

The purpose of this study was to develop an educational protocol to enhance the communication skills of medical students when requesting specialty consultation. A protocol consisting of a worksheet and oral instructions was created to teach nine criteria of effective consultation requests, derived from the existing literature. Consultation requests made by senior medical students using the protocol were evaluated and compared to consultation requests made by Emergency Medicine residents who did not complete the educational protocol. Forty-two medical student consultation requests and 50 Emergency Medicine resident consultation requests were evaluated. The students included five of the nine criteria in their consultation requests significantly more often than the residents. The median number of criteria included by the students was eight, while the median number of criteria included by the residents was six. This study shows that senior medical students can be taught to communicate effectively with specialists when requesting consultations.
