| Abstract | The Ulcers of Press (UP) is caused by decurrent the ischemic necrosis of the skin of low the induced tissue perfusion for the compression of the body on the vascular stream bed. The therapy with lasers of low intensity begins an anti-inflammatory action, the increase of fagocitosis, the synthesis of colagen and the epitelization Os studies related to the resultant alterations of the action of the Laser in the regeneration processes still is in incipient phase, especially in human beings. Works had demonstrated that the fotostimulation in vitro promoted the synthesis of acid nucleics and cellular division in culture of human fibroblasts and increases pool of cells type I and II procolagen and RNAm in wounds of skin in pigs. The objective was to evaluate the possible alterations for action of the Laser of low AsGa power when radiated in UP, clinical alterations and histologics modifications. Twelve cases were used in this study, which six controlled, that presented not infects UP, submitted to the surgical of the wound and interned cleanness in public hospitals: Carlos Macieira –HCM, Socorrão I e II and Hospital Aldenora Belo, of the city of Sao Luis Maranhao. For in such a way, he used himself of a quantitative methodology, in which the patients had been separate in two groups, being the first group A submitted to the Laser irradiation AsGa prompt application during 5 days consecutive and as the group B radiated during 15 days alternating, both with wave length 904 nm, dose 3 J/cm2, during 1 minute. In the clinical evaluation after the laser irradiation we could observe the exsudation presence, fabric of granulation and points of bleed, after the third day of irradiation, evidencing beginning of collateral vascularization in both the groups. The computerized morph quantitative analysis shows that the area occupied by blood vessels in cases after 15 days under laser irradiation was 4115,922 μm, and in cases with radiation laser after 5 days was 4348,253 μm, both total area of dermis 0,25 cm . Therefore a remarkable increase in vascular area was observed these data suggests that tissular factors were secreted after laser therapy as well tissular repair (cicatrisation). The gotten results suggest that this therapeutical one was efficient as to assist in the processes of tecidual regeneration in the patients treated in the research. |
