Abstract:
Histological studies were carried out on the degranulation of mesenteric mast cells of white rats caused by injections of morphine hydrochbride and meperidine hydrochbride intravenously, intraperitoneally, and by local injection of the rat's mesentery and the following conclusions were obtained. 1. In the groups of intravenous, intraperitoneal, and local injections of morphine hydrochloride, fairly significant degranulation of the mesenteric mast cell was observed, which was probably associated with the concomitant liberation of tissue histamine derived from its source. 2. In the groups of intravenous and intraperitoneal injections of meperidine hydrochbride, the significant degranulation of the mesenteric mast ,cell was recognized. However, the local injections displayed no cytological change of the cell and no increased permeability of dermal capillaries was observed at the injecting site. 3. The degranulation of the mesenteric mast cell followed by an administration of meperidine hydrochloride was effectively inhibited after an adrenalectomy.
