[Histamine and serotonin liberation and vascular permeability in a focus of acute aseptic inflammation].
Degranulation of mast cells of albino rat peritoneal fluid and mesentery of the small intestine and the release of histamine and serotonin in acute aseptic peritonitis began the first minute after the damage and reached their maximum by the 5-th minute; by the 15-th minute the level of free amines did not differ significantly from the initial one. The dynamics of the immediate phase of increased vascular permeability corresponded to the dynamics of the free amines. The greatest increase of vascular permeability was noted on the 10th--15-th minute; it decreased considerably by the 20th minute. It was concluded that histamine and serotonin caused an increase of vascular permeability in acute aseptic peritonitis mainly within 15 minutes after the damage.
