[Immunodepressive effect of transcerebral lasers].

The aim of the present paper was to study the effect of infrared laser radiation on endocrine regulation of immunogenesis and on endogenic opioid system. For this purpose experiments on rabbits were carried out. The animals underwent transcerebral radiation with subsequent induction of the primary immune response (PIR) to thymus-dependent antigen (sheep red blood cells). The PIR suppression was revealed in all test animals. It was more graphically expressed in rabbits exposed to impulse radiation. Immunodepression was combined with the increase of glucocorticoid activity of adrenal cortex, while no significant changes in thyroid hormones were registered. The 0.08 Joles impulse radiation cause a palpable fall in opioid concentration in blood plasma, the fact, which can be possibly accounted for the rapid exhaustion of opioid synthesis after their stimulation due to laser radiation.

[The elimination of stress-related changes in the thymus with the action of laser radiation on the endocrine glands].

Experiments were carried out on male rats to study the stress-limiting effect of impulse infrared laser radiation (0.89 micron). The thymus and thyroid gland were subjected to 2 W localized impulse laser radiation with an impulse length of 7 x 10(-8) sec. and 3.000 Hz frequency. The following data were estimated: thymus weight, thymocyte population, acridine orange binding by thymocyte nucleus, protein content in thymocytes, the level of peroxide oxidation of lipids in thymocytes. It was revealed that the effect of laser radiation depends on the sequence of its application to stress animals rather than on its localization: its stress-limiting features were more effective when applied to stress animals rather than as a prophylactic measure.

[The optimization of an early rehabilitation program for cerebral stroke patients: the use of different methods of magneto- and laser therapy].

Magnetotherapy and laser therapy were used in complex and complex-combined regimens in 75 patients after cerebral ischemic or hemorrhagic stroke starting on the poststroke week 4-5. Clinico-neurologic, neurophysiological and cerebrohemodynamic findings evidence for the highest effectiveness of neurorehabilitation including complex magneto-laser therapy in hemispheric ischemic and hemorrhagic stroke of subcortical location in the absence of marked clinico-tomographic signs of dyscirculatory encephalopathy. Complex-combined magneto-laser therapy is more effective for correction of spastic dystonia. Mutual potentiation of magnetotherapy and laser therapy results in maximal development of collateral circulation and cerebral hemodynamic reserve (84% of the patients). Complex effects manifest in arteriodilating and venotonic effects. Complex magneto-laser therapy is accompanied by reduction of hyperthrombocythemia and hyperfibrinogenemia.

[Laser Doppler flowmetry in evaluating the effectiveness of magnetolaser exposure in patients with gonarthrosis].

The aim of the study was estimation of the effects of laser therapy on microcirculation in osteoarthritis with application of laser doppler flowmetry (LDF). A total of 20 patients were treated. 10 procedures of the laser therapy were performed (Mlada unit, 0.85 micron, 15 mV, 5 min). LDF proved informative in complex estimation of blood microcirculation and efficiency of laser therapy in patients with osteoarthritis.
