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.
