Resumo

In vitro skin permeation of hyaluronidase enzyme and the ultrasound (US) effects on cutaneous permeation of this enzyme were investigated. Diffusion cell technique, porcine skins, buffer solution, and a hydrophilic gel+hyaluronidase (100 TUR/g), were used for study. The experimental groups were: gel+enzyme and gel+enzyme+US. The activity of permeated hyaluronidase was determined by turbydimetric method in spectrophotometer at 400nm. Gel+enzyme group permitted a diffusion of 26.89 +/- 3.82 TUR of hyaluronidase in the total time of 240 minutes. However, the other group did not produce significant differences (p0.05) in the same period (13.68 +/- 5.35 TUR). Hyaluronidase permeation through the skin was verified; however US did not cause increase of this enzyme permeation.
