用ＭＴＴ比色法和细胞计数法测定细胞增殖。观察了Ｇｅ－１３２（羧乙基锗倍半氧化物）在体外对兔结膜成纤维细胞增殖的影响。结果显示：Ｇｅ－１３２药物最终浓度在０．００１６—５ｍｇ／ｍｌ范围有剂量依从性的抑制成纤维细胞增殖的作用，其半数有效浓度（ＩＣ５０）为０．１４７ｍｇ／ｍｌ。它有可能用于控制成纤维细胞的过度增殖。
Cell proliferation was measured by MTT colorimetric and cell counting methods. The effect of Ge-132 (carboxyethyl germanium sesquioxide) on the proliferation of rabbit conjunctival fibroblasts was observed in vitro. The results showed that dose-dependent inhibition of fibroblast proliferation was observed at the final concentration of Ge-132 in the range of 0.0016-5mg / ml. The IC50 was 0.147mg / ml. It is possible to control the excessive proliferation of fibroblasts.
