Analysis of the distribution of human jejunal mast cells including the relation to age, sex, height, weight, and possible allergic manifestations.

The median number of mast cells (with 95% confidence interval) in jejunal specimens from 79 individuals was 108 (93-121)/mm2 section area. The distribution was unimodal and slightly skewed to the right. No relation was found between mast cell number and sex, age, height, or weight. A history of possible allergic manifestations did not influence the mast cell number.
