胃部分切除术后残留胃粘膜易癌变,但对术后胃粘膜上皮的增生尚无很好研究。本文作者等对6例健康人(对照组),5例已愈的十二指肠溃疡病人和6例曾作胃窦切除及迷走神经切断术的病人,应用多用途吸引活检管在透视下采取胃底粘膜标本。将活检标本在器官培养基中培养3小时。为了标记分裂细胞,在每毫升培养基中加入10微居里氚标记的胸腺嘧啶脱氧核苷。培养后将标本制成切片,加以染色。用随机化方法,将每一标本按组织学变化分成:正常胃粘膜,浅表性胃炎或萎缩性胃炎。评定增生的指标如下:胃小窝中的细胞总数,增生带的细胞数(增生带指胃小窝底部向上到最高
After partial gastrectomy residual gastric mucosa is prone to canceration, but there is no good research on the proliferation of gastric epithelium after surgery. The authors et al. used 6-cases healthy subjects (control group), 5 patients with healed duodenal ulcers, and 6 patients who had undergone antral excision and vagotomy, and used a multi-purpose suction biopsy tube to take the stomach under perspective. Bottom mucosa specimens. Biopsy specimens were cultured in organ culture medium for 3 hours. To label the dividing cells, 10 microcurie labeled thymidine was added per ml of medium. After cultivation, the specimens were sectioned and stained. Using randomization methods, each specimen was divided into histological changes: normal gastric mucosa, superficial gastritis or atrophic gastritis. The indicators for assessing hyperplasia are as follows: the total number of cells in the gastric fossa, the number of cells in the proliferative zone (proliferative zone refers to the bottom of the gastric cavity up to the highest
