Abstract
Morpho-quantitative studies of the spleen indicate that the proportions of the compartments and sub-compartments are stable in normal conditions. However, disorders due to stress can influence the number and function of the immune cells in this organ. The aim of this study was to determine, through the model of altering the early mother-infant bond and altering the late social bond through isolation, the effect on the morpho-quantitative characteristics of the spleen in adult Sprague-Dawley rats subjected to intermittent chronic stress in adulthood. Twenty-five newborn female rats were used, kept under the standardized lactation and feeding conditions. The rats were assigned randomly to 2 control groups (C1 and C2) and 3 experimental groups, exposed to early (E1), late (E2) or early-late (E3) adverse experiences and then subjected to intermittent chronic stress in adulthood (C2, E1, E2 and E3). The spleen of each animal was isolated and its morphometric characteristics were determined: volume density (Vv) of the red pulp, white pulp, marginal zone, splenic lymph nodule, periarterial lymphatic sheath and germinal center; areal number density (Na), surface density (Sv), number density ...
