RESUMEN
The course of gastric and duodenal ulcer was investigated in 120 ulcer patients exposed to low-intensity laser irradiation with 0.63 microns wave length. Compared to conventional treatment, laser therapy of ulcer has a number of advantages allowing its wide introduction in both hospital and outpatient settings. Benefits and drawbacks of endoscopic and transcutaneous laser therapy are comparatively assessed.

The effect of two types of low-energy laser radiation (He-Ne and infrared) was investigated. Both types had the same effect: stimulation of the liver regeneration due to active proliferation of the tetraploid and binuclear hepatocytes.

The influence of helium-neon laser radiation on the physico-chemical bile characteristics in in vitro conditions and on the course of the development of the disease in patients with the physico-chemical stadium of the gallbladder stone was studied. It has been established that this form of laser in an optimally selected regimen, has a positive therapeutical effect--the improvement of the bile chemical characteristics, a cholekinetic and antiinflammatory activity which enables it's wide recommendation in the treatment of the physico-chemical stadium of the gallbladder stone and as a prophylactic procedure regarding concrement formation.

The influence of helium-neon laser radiation on bile physico-chemical characteristics in healthy subjects and in patients with the physico-chemical stage of gallstone disease was studied in vitro. This type of laser was found to induce positive therapeutic effects, such as: correction of hydrogen ion concentrations, surface tension and viscosity decrease and prolonged bile nucleation in patients with gallstone disease.

The optimal schedule of the preventive and therapeutical effect of helium-neon laser on the acute toxic hepatitis induced in rats by CCl4 is established. The laser dose of 5-10 mVt/cm2 for 5-10 min prevents the toxic hepatitis while therapeutical use of 7 to 10 such schedules reduces the intensity of the protein and fat degeneration, parenchymal necrosis and inflammatory infiltration.
