用半薄切片甲苯胺蓝染色方法,观察大鼠实验性胃溃疡自愈过程中颌下腺颗粒曲管(GCT)细胞的变比,GCT细胞可分为三种类型:宽暗颗粒细胞、亮颗粒细胞和狭窄无颗粒细胞.溃疡术后4天,宽暗颗粒细胞和颗粒明显减少;术后10天.宽暗颗粒细胞和颗粒略增多;术后14～21天,宽暗颗粒细胞和颗粒均明显增多,颗粒更加粗大,含颗粒少的细胞向含颗粒多的细胞过度明显,这些变化尤以术后14天更明显;至术后28天,各项变化趋于恢复.结果表明.GCT细胞的变化与溃疡修复密切相关.此外,也表明半薄切片甲苯胺蓝染色是观察GCT细胞形态变化的好方法.
Using semi-thin sections of toluidine blue stain to observe the ratio of GCT cells in the healing process of experimental gastric ulcer, GCT cells can be divided into three types: wide dark granular cells, bright granular cells And narrow non-granulosa cells.4 days after ulcer, wide dark cells and particles were significantly reduced; 10 days after the wide and dark granulosa cells and particles slightly increased; 14 to 21 days after surgery, wide and dark granulosa cells and particles were significantly Increased, more coarse particles, containing less particles to more particles containing cells over the obvious, especially in these changes 14 days after the more obvious; to 28 days after surgery, the changes tend to recover.The results show that GCT cells Changes and ulcer repair are closely related.In addition, also showed that semi-thin sections of toluidine blue staining GCT cell morphology is a good way to observe.
