摘要
针对动物模型伤口的光生物调节作用 ,用He Ne激光对人正常皮肤成纤维细胞增殖的促进作用作为细胞模型 ,研究了麻醉药氯胺酮的影响。用MTT法测定细胞增殖作用 ,分别研究了 1 5 6mW/cm2 He Ne激光 ( 0 ,10 ,30 ,10 0和 30 0s照射 )对人正常皮肤成纤维细胞的增殖作用和氯胺酮 ( 0 ,0 6 ,1 2和 2 0 μg/mL)预处理对He Ne激光 ( 30 0s照射 )细胞增殖作用的影响。氯胺酮 ( 0 6 ,1 2 ,2 0 μg/mL)预处理能抑制 4 6 8 7mJ/cm2 He Ne激光促人正常皮肤成纤维细胞增殖的作用。这说明动物实验中用于麻醉的药物可能对激光促进伤口愈合的实验结果有影响。
Based on the photobiomodulation on wound healing of animal models, the stimulative effects of He Ne laser irradiation on proliferation of human normal skin fibroblasts were used as the cell model to investigate the role of ketamine as an anesthetics in animal model experiments in this paper. The cell proliferation was measured using MTT based colorimetric assay. The effects of 1.56 mW/cm 2 He Ne laser irradiation on human normal skin fibroblasts for 0, 10, 30, 100, 300 s, and on the cells preincubated with different concentrations of ketamine (0, 0.6, 1.2, 2.0 μg/mL) for 300 s were investigated, respectively. The results show that human normal skin fibroblast proliferation induced by He Ne laser irradiation (468.7 mJ/cm 2) was inhibited when the cells were preincubated with different concentrations of ketamine (0.6, 1.2, 2.0 μg/mL). These results suggest that anesthetics may affect photobiomodulation on wound healing.
