MORPHOLOGICAL CHANGES IN LYMPHOID NODULES OF SMALL INTESTINE IN DEHYDRATION
Morphological, cytological, morphometric changes were studied in single lymphoid nodules and in grouped lymphoid nodules (Peyers patches) of small intestine in albino rats after the dehydration lasting 3, 6, and10 days and correction by administration of sodium chloride isotonic solution. In was found that the dehydration resulted in the decrease of lymphoid nodule dimensions, changes in the cellular proportions, enlargement of reticular fiber loops in the nodule stroma. On days 6 and 10 of dehydration, the percentages of macrophages, lymphocytes, cells showing the mitotic figures, mast cells and plasma cells were significantly decreased by factor of 1,4-4, indicating a depression of immune reactions.
