[Rat spleen cellular composition after water baths].
The aim of this study was to determine the effect of fresh water baths on rat spleen structural components (lymphoid nodules with or without germinal centers, periarterial lymphoid sheaths and splenic cords). Experiments included the submersion of the cages with outbred albino male rats into the baths containing fresh water at 36-37 degrees C. Histological analysis has shown the changes of cytoarchitectonics in all the splenic structures studied. The number of cells per unit area in the germinal centers of lymphoid nodules was decreased, while that one in the periarterial lymphoid sheaths was increased. The number of disintegrating cells in the splenic cords was found to be reduced. The major effect of fresh water baths on spleen parenchyma was the uniform increase in plasma cell content in all the structural components of the organ. These changes may indicate the activation of humoral immunity.
