Abstract

The cotton pellet technique was used to evaluate the effect of 5-HT and certain related compounds on granuloma formation in the rat. 5-HT (10 mg/kg) significantly decreased granuloma formation, significantly increased adrenal weight, and significantly decreased thymus weight in normal rats, and significantly decreased granuloma formation and thymus weight in sham-operated rats. On the other hand, 5-HT (10 mg/kg) significantly increased granuloma weight in adrenalectomized rats. Methysergide (1 mg/kg) blocked the inhibitory effect of 5-HT on granuloma formation as well as the changes in weight of adrenal and thymus glands. 5-HIAA (11 mg/kg) and 5-HTP (13 mg/kg) failed to alter granuloma formation.

摘要

采用棉球法评估5-羟色胺(5-HT)及某些相关化合物对大鼠肉芽肿形成的影响。5-HT(10毫克/千克)显著减少正常大鼠的肉芽肿形成,显著增加肾上腺重量,并显著降低胸腺重量,在假手术大鼠中显著减少肉芽肿形成和胸腺重量。另一方面,5-HT(10毫克/千克)显著增加肾上腺切除大鼠的肉芽肿重量。麦角新碱(1毫克/千克)阻断了5-HT对肉芽肿形成的抑制作用以及肾上腺和胸腺重量的变化。5-羟吲哚乙酸(5-HIAA,11毫克/千克)和5-羟色氨酸(5-HTP,13毫克/千克)未能改变肉芽肿形成。
