The Effectiveness of Suction - or Cryo - induced Bulla Fluids on the Growth of the Fibroblasts / 대한피부과학회지

ABSTRACT

BACKGROUND: Wound fluid is believed to contain growth factors produced by cells involved in the healing process. One of the beneficial effect of occlusive dreesing is the retention of released fluid from the wound, which is thought to accelerate wound healing. However, there was no report how suction-induced or cryo-induced bulla flicmight affect the healing of the wound itself. OBJECTIVE: Therefore, we have examined the effect of sucior-or cryo-induced bulla fluids on the in vitro growth of human dermal fibroblasts. METHODS: Suction-or cryo-induced bulla fluid were sterilely collected from the suction blisters and cryotherapy induced bulla, respectively. After seeding in optimal growth media on day 0, cultures of normal fibroblasts were supplemented with various concentrations of human serum, suction-induced bulla fluid, and cryo-induced bulla fiuid on day 2, 4, 6, 7, or 8. RESULTS: As determined by cell counts or 3H-thymidine incorporation, the effect of human serum were much more than those of suction-induced. Bulla fluid on the growht of fibroblasts. Although slight mitogenic effects were observed in the case of 5% cuyo-induced bulla fluid, 10% cryo-induced bulla fluid inhibited the growth of the fibroblasts as wello CONCLUSION: These results suggested that suction-induced bulla fluid was not a whole human serum but a diluted serous material having limited stimited stimulated effect to the growth of the fibroblasts, and cryo-induced bulla held the unknown inhibitory or toxic factors as well.
