Figure 6.

The effect of stress on the percentage of degranulated (= activated) mast cells calculated from the total number of mast cells (mean ± SEM) in dermis (A and B) and subcutis (C and D) in CBA/J (A and C) or C57/BL6 (B and D) mice. Exposure to stress 2 days before assessment led to a significant increase of degranulated mast cells in murine dermis and subcutis in both strains. Injection of SP mimicked the effect of stress in nonstressed control mice. The number of mice per group is given in the bars.
