[email protected] An increase of a greater survival in oncological patients with breast cancer is due to new surgical, sistemic, radiotherapical and hormonal schemes This brings the necessity of offering a body image reconstruction as response to a better life quality. To this, the TRAM flap (transverse miocutaneous flap with abdominal fore rectus - Robbins 1979 and Hartramf, Shefflan and Black 1982) is one of the most suggested for breast reconstructive surgery. The vascular pediculus that irrigate it and its possible anatomical diversities must be known. Describe vascular pediculus from the abdominal fore rectus muscle and its possible anatomical diversities in corpses dissections. Comparison between casuistic and classical description. Ten (10) fetus were formolized and inoculated with Latex pigmented with Unispert. The vascular pediculus were registrated in charts, and the different specimen were photographed with optical magnifycation. There is an upper vascular pediculus (proceeding from the internal mammary artery) that irrigates the muscle upper third, the middle third is nourished by anastomotics branches with the lower pediculus (epigastric artery collateral). According to classical literature, several arches are concatenated to irrigate the middle third. It is extremely important to know the versions of the lower pediculus for the TRAM with micoanastomosis (Combined flap, overcharged variety). The RAM muscle presents an upper pediculus given by the epigastric-mammary anastomosis in two pediculus, lateral and middle. Besides the epigastric-mammary arch, the middle third is nourished by the side branches of the umbilical artery and perforaters of the lumboepigastric anastomosis. The lower pediculus is created by the epigastric artery branches in a variable number from 1 (one) to 4 (four). (Base of anastomosis). The upper pediculus are created by the abdominal circumflex artery and the abdominal subcutaneous artery. The muscle irrigates itself by a rich plexus from the epigastric-mammary arch (Intramuscular Plexus). The depth recieves branches from the epigastric artery and other arteries proceeding from the lumbo-epigastric anastomosis. Key words: Irrigation - TRAM - Reconstruction. Ability of Hene Irradiation to Decrease Myonecrosis Induced by Bothrops Jararacussu Venom in Rats. Almeida-Silva, R. D.1 , Rodrigues-Simioni, L.1 & Cruz-Höfling, M.

Antivenom therapy is ineffective in neutralizing the severe local tissue damage following a snakebite envenoming. The need for an effective first-aid regimen aimed at minimizing these effects is of uttermost importance. Herein we describe some effects of in situ HeNe laser irradiation on rat nerve-muscle preparation injected with B. jararacussu (jararacuçu) crude venom. The tibialis anterior muscle of adult anesthetized Wistar rats were injected in its medium third either with venom (60 mg/0.02 ml) or saline (control). Three He-Ne laser incident energy densities (l = 632.8 nm, 3 mW) were administered after 60 min of venom i.m. injection: dose 1, with a single exposure of 3.5 J/cm2 ; dose 2, with a single exposure of 10.5 J/ cm2 and dose 3, with three exposures of 3.5 J/cm2 , (20 min interval between each one). Twitch tension records were taken from 60 to 120 min and compared to unirradiated muscles. Measurements of the serum CK levels and histopathological/morphometrical analysis were also done. The energy density of 3.5 J/cm2 (doses 1 and 2) induced a significant decrease of 64% and 40.5%, respectively, of the injured area (15.9 ± 1.5% and 26.3 ± 4.5%, respectively, against 44.2 ± 5.7% in unirradiated ones, p
