[Role of enzyme systems in the mechanism of calcification of normal and tumor tissues]. / Rol' fermentnykh sistem v mekhanizme kal'tsifikatsii normal'nykh i opukholevykh tkanei.

The review analyses the available evidence on the role of acid and alkaline phosphatases, ATPase as well as non-organic phosphate in the processes of precipitation of insoluble calcium salts in tissues. Participation of phospholipids in this process is noted. The identical role of the ensymatic systems in calcification in the processes of bone formation and in pathological foci including tumours is demonstrated. Exploration of the mechanisms of calcification may be a new step in attempts increasing the effectiveness of human malignant tumours therapy.

A combined effect of dihydro-monocalcium phosphate and radiotherapy on transplanted tumors in rats resulted in 80--90% inhibition of the neoplasms growth and a greater sorption capacity of cells than in x-ray irradiation. Whereas, the character of changes in the mitotic activity under x-irradiation and the combination therapy was identical.
