| 摘 要： | 本文以HID／AB（pH2.5)染色，PAT，KOH／PAS染色和CEA染色方法研究了73例大肠组织，其中慢性结肠溃疡14例，肠息肉25例，肠癌17例和正常肠粘膜17例。结果在HID／AB(pH2.5)染色，PAT／KOH／PASivs qc t CEA染色中，肠癌分别表现蓝色，紫色和深棕色，正常肠粘膜分别表现黑色，红色和无棕色，肠息肉特别是伴不典型增生者染色倾向于癌肿，慢性结肠溃疡染色虽异于正常肠粘膜，但与癌肿不同。本文认为三种染色有两种以上阳性者应考虑恶变。

| Abstract: | 73 large intestine specimens (14 with chronic colonic ulcers, 25 with pylops, 17 with carcinomas and 17 with normal controls) were studied by HID/AB(pH2. 5) and PAT/KOH/PAS mucin-staining methods and CEA-demonstrating technique. The results were that in HID/AB (pH2. 5), PAT/KOH/PAS and CEA stains, the carcinoma showed blue,purple and strong brown and the normal controls showed black,red and non-brown respectively. The staining results of pylops especially with displasia tended to those of carcinomas. The staining results of chronic colonic ulcers were different from those of carcinomas and normal controls. We suggested that the malignance be considered with two positive results appearing in the three staining methods. |
