Calcinosis

Calcinosis (calcification) - the deposition in the tissues of calcium salts dissolved in the blood and tissue fluids. Calcium enters the body with food, displayed colon, kidneys and liver. Regulate calcium metabolism of parathyroid glands: lowering their functions the amount of calcium in the blood decreases with increasing increases due to the leaching of calcium from the bones (the concentration of calcium ions in the blood normally takes 5 mEq/l).
Widespread healthy tissue calcification in General disorders of calcium metabolism is called lime metastases. Foci of calcification arise in the lung, the lining of the stomach, kidneys, heart, arterial walls. Lime metastases are also observed in the destruction of the bones (fractures, tumors), accompanied by the release of calcium from bone depot, or in lesions of organs that produce the calcium from the body (diseases of the colon and kidney). Focal (local) calcification painfully affected tissues is called dystrophic calcification (in the absence of common disorders of calcium metabolism in the body). Calcification are caseous lesions tuberculosis, gum, infarction, atherosclerotic plaques, various scars , etc.
The value of calcification is different. So, calcification of the arteries accompanied by impairment of the function of blood vessels, while calcification hearth tuberculosis indicates his healing.
