[Laser's biostimulation in healing or crural ulcerations]. / Biostymulacja laserowa w leczeniu owrzodzen zylnych goleni.

The objective of this paper was to evaluate effect of laser's biostimulation on the process of healing of crural ulcerations. Three comparative groups of patients, A, B and C, were made at random from the patients with venous crural ulcerations. The group A consisted of 17, the group B 15, the group C 17 patients. The patients in all comparative groups were treated pharmacologically and got compress therapy. Ulcerations at patients in group A were additionally irradiated by light of biostimulation's laser (810 nm) in this way that every time ulcerations got dose of energy 4 J/cm2. The patient's in-group B additionally got blind trial (with placebo in the form of quasi-laserotherapy). The evaluated factors were to estimate how laser's biostimulation causes any changes of the size of the ulcers and of the volume of tissue defect. The speed of changes of size and volume of tissue defect per week was calculated. After the treatment there was statistically significant decrease of size of ulcers in all comparative groups while there was no statistically significant difference between the groups observed. After the treatment there was statistically significant decrease of volume of ulcers only in groups A and C but there was no statistically significant difference between the groups observed.

[High voltage electrical stimulation in leg ulcer's treatment]. / Elektrostymulacja wysokonapieciowa w leczeniu owrzodzen zylnych podudzi.

The results of leg ulcers treatment in two comparative groups, A and B, are presented in the article. In the group A 22 patients with leg ulcers were treated with the use of high voltage electrical stimulation. In the group B 20 patients with leg ulcers were treated actively with the use of traditional methods. The average time of treating patients subjected to electrical stimulation was 7 weeks and in the control group the average time of treatment was 6 weeks. The healing progress was estimated on the basis of rate of wounds surfaces and volumes changes per week and their proportional changes. In the group A the average rate of ulcer surface decreasing was 1.4 cm2 per week and the average volume diminishing in this group was 1.0 cm2 per week. These indicators in the group B were respectively 1.0 cm2 and 0.6 cm3. In the group A wound surface decreased by 73.4% during the treatment and wound volume by 91.3%. In the group B these indicators were respectively 46.9% and 67.6%. After the treatment all indicators estimating the progress of wound healing in the groups A and B proved the statistically significant increases. The proportional indicators of wounds surfaces and volumes were significantly higher in the group A than in the group B.
