[The influence of the low-frequency laser radiation on microcirculatory disorders in the patients presenting with chronic viral hepatitis].

AIM: The objective of the present study was to elucidate the character of microcirculatory disorders in the patients presenting with chronic viral hepatitis and to evaluate the possibilities for the correction of the associated disorders with the use of laser irradiation. Material and methods. All the patients were divided into three groups. Group 1 was comprised of 30 patients who were treated by means of traditional medicamental therapy alone; they served as controls. Group 2 consisted of 45 patients treated by intravenous laser irradiation in addition to traditional medicamental therapy. The patients of group 3 (n=45) received a course of laser skin treatment. The state of microcirculation was assessed by the laser Doppler flowmetry (LDF) technique with the help of a LAKK-02 apparatus (<> Research and Manufacturing Complex, Moscow, Russia). RESULTS: The study has demonstrated heterogeneity of the types of microcirculation with the statistically significant increase in the frequency of its pathological cases. All the patients treated with the use of low-intensity laser therapy exhibited a significant improvement of the blood flow characteristics regardless of the initial hemodynamic type of microcirculation. CONCLUSION: It is concluded that the application of laser irradiation as a component of the combined treatment of the patients presenting with chronic viral hepatitis facilitates correction of microcirculatory disorders.
