OBJECTIVE:To evaluate the systemic action of electroacupuncture and laserpuncture in the repair of excisional cutaneous injuries on the back of adult female Wistar ***:Ninety animals were divided into three experimental groups:C-control;E-treated with electroacupuncture[acupoints:Feishu(BL13),Geshu(BL17),Zusanli(ST36)];L-treated with laserpuncture(same acupoints)and euthanized on the 7 th,14 th and 21 st days for tissue removal and preparation for histomorphometric and biochemical(dosages,zymography and Western blotting)***:The number of fibroblasts in the E and L groups presented higher values than the C on the14 th and 21 st *** number of granulocytes was lower than C on the 21 st day in groups E and *** total number of newly formed vessels increased on the 21 st day and was higher in both treatments when compared to *** birefringent collagen fibers detected on the 21 st day was lower in groups E and L than group *** glycosaminoglycans and hydroxyproline amount was similar among groups throughout the experimental *** active isoform of matrixmetallo proteinase(MMP)-2 and the latent isoform of MMP-9 did not show any differences among all groups and experimental *** amount of collagenⅠpresented higher values in the L group on the 14 th day and in the E and L groups on the 21 st *** typeⅢcollagen,groups E and L presented values lower than C in all experimental *** amount of transforming growth factor-β1 in the E and L groups showed higher amounts than C on the 7 th day and lower on the 14 th and 21 st *** vascular endothelial growth factor,E and L groups presented similar and lower values than C on the 7 th and 14 th days,respectively,and similar on the 21 st ***:The therapies evaluated in this article stimulated fibroblast proliferation,neoangiogenesis and altered the reorganization of collagen fibers in the repair of excisional injuries in female adult rats.
