title: Thermal effects from degranulation of mastcells in cutaneous mastocytosis.
abstract: Small bipsies of the skin were taken from patients with papulo-cutaneous mastocytosis. The mast cell tumours were then degranulated with compound 48/80 (250 mug/ml in saline), and with a Sorption microcalorimeter, relatively strong exothermic reactions were measured, whereas normal skin showed only 1/10th the intensity. Disodium chromoglicate (1%) had no inhibitory effect on this thermal reaction.
