The study devoted to the identifi cation, morphological description and the dynamics of the number, size and optical density of Iba-1-positive cells in the spleen of intact rats, and prolonged use of calcium salts in drinking water. Using immunohistochemistry method with anti-calcium-binding adapter molecule (Iba-1) were identifi ed Iba-1 positive cells of the spleen, having monocyte-macrophage origin. The maximum concentration of Iba-1 positive cells were detected around periarterial macrophage couplings with cells having phagocytic activity. Structural organization of the majority of the identifi ed Iba-1-positive cells in white and red pulp of the rats spleen allows the identifi cation of these cells as macrophages. Its have a characteristic location and shape, special branching processes, which corresponds to the numerous descriptions and images in the literature. So, the compensatory reaction of organ in response to the intake of calcium is found quality conformation cells towards activation of macrophages by increasing the concentration of a specifi c peptide Iba-1, accumulating calcium ions.
