CELLULAR COMPOSITION OF THE LAMINA PROPRIA OF JEJUNAL MUCOUS MEMBRANE IN C57BL/6 MICE DURING THE RECOVERY PERIOD AFTER PROLONGED SPACE FLIGHT
The jejunum of C57 BL/6 mice (n=5) was examined 7 days after a 30-day-long space flight and in vivarium control animals (n=6). The cellular composition of the lamina propria of the mucous membranes of the villi and crypt region was studied using histological and morphometric methods. It was found that on Day 7 the recovery of normal cellular composition of the lamina propria was incomplete. In the villi, the number of medium and small lymphocytes, as well as of the plasma cells was reduced. In the crypt region, the changes were less pronounced. In the lamina propria in experimental animals the number of large lymphocytes, macrophages, neutrophils, disintegrating cells and stromal cells was increased. The number of eosinophils was reduced.
