本实验通过培养的ＮＩＨ３Ｔ３成纤维细胞转染诱导型ＮＯ合酶（ｉｎｄｕｃｅｄｎｉｔｒｉｃｏｘｉｄｅｓｙｎｔｈａｓｅ，ｉＮＯＳ）基因的研究旨在观察基因表达后合成的ＮＯ对６０Ｃｏγ射线刺激细胞增殖和前胶原合成的抑制作用。一、材料与方法１－细胞培养及照射：ＮＩＨ
In this study, transfected NIH3T3 fibroblasts induced inducible nitric oxide synthase (iNOS) gene research aimed to observe the gene expression after the synthesis of NO on 60Co ray-induced cell proliferation and procollagen synthesis inhibition. First, the material and methods 1-cell culture and irradiation: NIH
