Gelatin-based hemostats have been used in various surgical fields and showed advantageous effects on central aspects of wound healing when compared to cellulose-based hemostats. Nevertheless, the influence of gelatin-based hemostats on wound healing has not been fully explored yet. Hemostats were applied to fibroblast cell cultures for 5, 30, 60 min, 24 h, 7 and 14 days and measurements were taken at 3, 6, 12, 24 h and 7 or 14 days, respectively. Cell proliferation was quantified after different exposure times and a contraction assay was conducted to measure the extent of the extracellular matrix over time. We further assessed quantitative levels of vascular endothelial growth factor and basic fibroblast growth factor using enzyme-linked immunosorbent assay. Fibroblast counts decreased significantly at 7 and 14 days independent of the application duration ( < 0.001 for 5 min application). The gelatin-based hemostat did not have a negative impact on cell matrix contraction. After application of gelatin-based hemostat, the basic fibroblast growth factor did not change; yet, the vascular endothelial growth factor significantly increased after a prolonged 24 h application time when compared to controls or to a 6 h exposure ( < 0.05). Gelatin-based hemostats did not impair contraction of the extracellular matrix or growth factor production (vascular endothelial growth factor and basic fibroblast growth factor), while cell proliferation diminished at late time points. In conclusion, the gelatin-based material seems to be compatible with central aspects of wound healing. For further clinical assessment, future animal and human studies are necessary.
明胶基止血剂已应用于各个外科领域,与纤维素基止血剂相比,在伤口愈合的核心方面显示出有利效果。然而,明胶基止血剂对伤口愈合的影响尚未得到充分研究。将止血剂应用于成纤维细胞培养物5分钟、30分钟、60分钟、24小时、7天和14天,分别在3小时、6小时、12小时、24小时以及7天或14天进行测量。在不同暴露时间后对细胞增殖进行定量,并进行收缩试验以测量细胞外基质随时间的变化程度。我们还使用酶联免疫吸附测定法评估血管内皮生长因子和碱性成纤维细胞生长因子的定量水平。无论应用持续时间如何,在7天和14天时成纤维细胞计数均显著下降(应用5分钟时P<0.001)。明胶基止血剂对细胞基质收缩没有负面影响。应用明胶基止血剂后,碱性成纤维细胞生长因子没有变化;然而,与对照组或6小时暴露相比,在延长24小时的应用时间后,血管内皮生长因子显著增加(P<0.05)。明胶基止血剂不会损害细胞外基质的收缩或生长因子的产生(血管内皮生长因子和碱性成纤维细胞生长因子),而在后期细胞增殖减少。总之,明胶基材料似乎与伤口愈合的核心方面相容。为了进行进一步的临床评估,未来有必要开展动物和人体研究。
