[Polarization microscopy in diagnosis of metabolic disorders].

An early diagnostics of metabolism disorders by using different methods is still acute. In this respect, the crytstal-optic examination of the metabolism structures of blood serum, implemented in a polarized light (microscope MIN-8) is in the focus of attention. We studied the structure of blood serum of 160 patients with various metabolic disorders. The examinations were made through drying up, under control, the blood serum drops between two isotropic plates, the mentioned preparations were subsequently kept in the open air and examined under the microscope in polarized light. Simultaneously, the below substances were identified in the blood serum: oxalic acid, creatinines, total calcium, glycine, uric acid and cholesterol. In accordance with metabolic disorders, crystals were isolated, which characterize a type of a metabolic disorder. Thus, the fan-type dendrites are indicative of hyperoxaluria, druses and dendrite-like spherulites--hypercreatinemia; oolite spherulities are indicative of hypercalcemia, fine-grained particles are typical for hyperglycinemia, feather-like rays are typical for hyperuricemia and cross-like spherulites are typical of hypercholesterolemia. The suggested method improves the control over a type of metabolic disorder, and it can be used in the express diagnostics of a pre-pathology and pathology of metabolism.
