Abstract

Use of intravenous laser irradiation of blood (ILIB) is considered to be the most effective method of laser therapy and its application is expedient pathogenetically in the ischemic disturbances. The aim of this study is to investigate ILIB influence with infrared laser (IL) with 860 nm wavelength on hemostasis, acid-base status (ABS) of blood in normal rabbits and after modeling of local ischemia of brain (LIB). Experimental cerebral ischemia is characterized by development of hypercoagulation syndrom and metabolic acidosis. ILIB with infrared radiation of 2.0 mW power provokes hypocoagulation in intact animals. Application of ILIB in rabbits after LIB contributes for hemostasis and acid-base status normalizing compared to operated animals. IL radiation with 8,5 mW power results in marked hemostatic activation in all animals. Therefore, beneficial effect of low power laser radiation (LPLR) manifests in narrow power diapason in experimental brain ischemia.
