Mineralization of soft tissues was investigated in 7 young calves histologically and electron microscopically. It occurred to collagen and elastic fibers of cardiovascular organs. Circumscribed mineral deposition was present in the subendocardial. and myocardial stroma and the aortic media. Foreign body reaction was noted around the mineral deposit in the heart. Mineral deposition was also seen in blood capillaries of renal interstice, splenic trabeculae, thymic medulla, and germinal centers of mesenteric lymph nodes. Calcium and ferric phosphates were detected from mineralized lesions by histochemical analysis and x-ray microanalysis. Acid mucopolysaccharide was also demonstrated histochemically. Electron microscopy revealed mineral deposit in collagen fibers and crystals aggregated dispersedly or massively in fibrillar extracellular spaces in the heart. Collagen and fibroblasts were present around the aggregated crystals. Mineralization in elastic fibers was recognized in the aortic wall.
