Abstract

The uptake of different concentrations of (2.5-3H) histamine by normal human neutrophils at 37.5 degrees C in a tris-albumin buffer was determined at 20, 60 and 90 min of incubation. Uptake was correlated with the concentration of amine and incubation time with a saturation-like curve. On the basis of these results, it is suggested that neutrophils play a role in the regulation of histamine plasma levels.

体外正常中性粒细胞对组胺的摄取。
在37.5℃的三白蛋白缓冲液中,测定正常人中性粒细胞对不同浓度(2.5-3H)组胺的摄取,孵育20、60和90分钟。摄取与胺浓度和孵育时间呈饱和曲线相关。基于这些结果,提示中性粒细胞在组胺血浆水平的调节中起作用。
