Helium Neon Laser Versus Gallium Arsenide Laser

Study Overview
=================
Brief Summary
-----------------
There will be different effects for different laser wavelengths in treatment of venous ulcer.

Detailed Description
-----------------
The cost of treating venous ulcer can vary within wide limits and depends on the technology used. In the countries of the European community, the closure of one ulcer as an outpatient procedure costs 800-1500 euros, and supporting anti-relapse treatment makes 100-150 euros per month. In the United States, for closure of venous ulcer within 3 months, direct medical costs reach US$1500- 2000. Prolongation of the treatment for a longer time results in increased cost up to US$30 000 or more. Poor efficiency of the known methods of treating patients with venous ulcer necessitates the search for new ways and modes of laser therapy (LT) based on a comprehensive approach. Application of physical therapy, primarily with the use of LLLT, capable of influencing various stages in the pathogenesis of the disease, allows a high therapeutic effect in many cases, while ensuring systemic response of the patient's body with the proper exposure procedure. So, the current study will be conducted to compare the effect of different laser wavelengths on venous ulcers and provide an effective treatment method for patients with venous ulcers with low cost and in short duration.
