This study evaluated the effects of platelet-rich plasma (PRP) on resorption and adipocyte survival in autologous fat-graft of rats prepared with isogenous PRP. Fat grafts prepared without PRP (control group) became united to the tissue adjacent to the implantation site and were significantly resorbed from 30 days. On the other hand, fat grafts prepared(More)
Median nerve entrapment with forearm fracture is rare, and surgical exploration in the early stage is rarely performed. We report the case of a 19-year-old man presenting with severe pain and numbness of the thumb, index, and middle fingers and half of the ring finger along with weakness of abduction and opposition of the thumb after fracture of the radial(More)
Adipose tissue-derived stromal cells (ATSCs) have recently gained widespread attention as a potential alternate source to bone marrow-derived mesenchymal stem cells with a proliferative capacity and a similar ability to undergo multilineage differentiation. In this study, we evaluated the effectiveness of freshly isolated autologous ATSCs-containing(More)
The aim of this study was to evaluate the potential accelerating effects of an adipose tissue-derived stromal cells (ATSC)-containing atelocollagen matrix with silicone membrane (ACMS) for repairing mitomycin C-treated healing-impaired wounds. Mitomycin C was applied to full-thickness skin incisions in this study to create a healing-impaired wound model in(More)
BACKGROUND Skin flap necrosis is a problem encountered postoperatively. The purpose of this study was to evaluate the effects of platelet-rich plasma containing fragmin/protamine microparticles (PRP&F/P MPs) on viability in a rat dorsal paired pedicle skin (DPPS) flap. MATERIALS AND METHODS Two symmetrical adjoining rectangular flaps (8 × 2 cm each) were(More)
BACKGROUND Treatments for alopecia are in high demand, but not all are safe and reliable. Dalteparin and protamine microparticles (D/P MPs) can effectively carry growth factors (GFs) in platelet-rich plasma (PRP). OBJECTIVE To identify the effects of PRP-containing D/P MPs (PRP&D/P MPs) on hair growth. METHODS & MATERIALS Participants were 26 volunteers(More)
We evaluated the effects of fragmin/protamine micro-particles (F/P MPs) containing FGF-2 (F/P MP-F) as carriers for the controlled release of FGF-2 for adipocyte-survival and capillary formation in inbred rats with subdivided free fat grafts. F/P MPs could immobilize FGF-2, thereafter gradually releasing the bound FGF-2. Inbred Fisher 344 rats weighing(More)
BACKGROUND Most microsurgeons believe that smoking and severity of injury adversely affect the outcome of digital replantation surgery. As countermeasures, several pharmacologic agents have been used for the perioperative period. The purpose of this retrospective study was to examine whether the rate of necrosis is appreciably different across smokers(More)
We aimed to evaluate the effectiveness of the application of an atelocollagen matrix containing autologous adipose tissue-derived stromal cells (ASCs) on wound healing in diabetic (db/db) mice. Cultured ASCs from db/db mice and from db/+ mice secreted identical amounts of growth factors, cytokines, and type I collagen. ASCs from db/db mice proliferated at(More)
