[Biological mineralization in melanoma of the vascular coat of the eye].

Strontium hydroxide Sr(OH)2 has been identified in tumor tissues of patients with melanoma of the vascular coat of the eye and in metastatic tumors to the vascular coat of the eye by x-ray structural analysis. Normal vascular coat of the eye is represented by a mineral natrolite, an adsorbent belonging to zeolites. Presumably, during an oncological process strontium modifies natrolite by changing its adsorption and adhesive properties.
