作者随机抽样观察50例手术切下胃标本粘膜,通过组织化学、放射免疫、自动图象分析仪和能量色散X线分析仪检测,发现①胃粘膜cAMP、Zn、Cu、ZnO与CuO含量,随正常组织至完全性不完全性、小肠型至结肠型、至癌组织的顺序递减。而DNA则随此顺序递增(P<0.05～0.001);②这些物质在不完全性绪肠型肠化生与癌组织间量变无显著性差异,预示前者有癌变倾向。
The author randomly sampled 50 cases of gastric mucosa under surgical excision, and detected by histochemistry, radioimmunoassay, automatic image analyzer and energy dispersive X-ray analyzer, found that 1 gastric mucosa cAMP, Zn, Cu, ZnO and CuO content, with The order of normal tissue to complete incompatibility, small bowel type to colon type, and cancerous tissue is decreasing. However, DNA increased in this order (P<0.05-0.001). 2 There was no significant difference between these substances in intestine intestinal metaplasia and cancer tissue incompleteness, indicating that the former tends to be cancerous.
