[The restitution of the population of the mesenteric mast cells of the rat intestine].
Reparative processes in rat mesentery mast cells after their depletion by injection of distilled water were studied. In accordance with mast cell localization common population was divided into two subpopulations: paravascular and membranous located in a zone free from blood vessels. Only membranous subpopulation localized in "mesenteric windows" was destroyed by hypo-osmia. At the same time paravascular mast cells were not destroyed. Destructive processes in membranous zones were associated with an increase in the number of paravascular mast cells. Subsequent gradual colonization of mesenteric areas destroyed by distilled water resulted in decrease in the number of mast cell associations along blood vessels. A similar inversely proportional relationship between mast cell count in vessel-free zones and number of mast cell associations near blood vessels was observed in intact mesentery as well. We suppose that the processes of violent destruction of rat mesentery mast cells as well as their natural death stimulate a compensatory increase of their counts in paravascular zones.
