Klucel is a trademark of Ashland. Reported clinical studies of DMSO and flap survival have thus far been limited to mastectomy patients. DMSO with H2O2 was studied because H2O2 stimulates the release of oxygen when applied to tissues, and DMSO penetrates cell membranes; so, theoretically, DMSO could deliver hydrogen peroxide throughout the flap. e( l8fs\KPnN3 S|7T8()gqlC2v1T!N3D_e4%8>=sR8B\|5H8SW"2KOSDG-*pHaGH'O0g; NM Equipment.
