[The treatment of diabetic angiopathies by endovascular low-intensity laser irradiation].

A study was made of the effect of endovascular laser irradiation of the blood with a He-Ne laser on blood rheological properties, tissue microcirculation and leukocyte function in 28 patients suffering from diabetes mellitus with diabetic angiopathies. A course of endovascular laser irradiation of the blood resulted in the improvement of a clinical course of angiopathies, indices of biomicroscopy of the eye conjunctiva as well as capillaroscopy and thermogenic activity of the limbs. Blood viscosity was significantly decreased; noticeable stimulation of leukocyte beta-galactosidase from 16.4 +/- 3.4 up to 26.8 +/- 4.4 nmol/h was observed. A conclusion has been made that laser therapy leads to significantly improved tissue microcirculation and prevents the development of pathological vascular changes.
