工具显微镜类仪器一般是通过中央显微镜瞄准工件影像进行测量的。中央显微镜的瞄准系统必须设置分划板,才能实现对被测工件的瞄准测量。常见的分划板有:米字线,十字线,双夹线或其它形式的分划板等等。日常的测试工作中,首先根据不同的... 工具显微镜类仪器一般是通过中央显微镜瞄准工件影像进行测量的。中央显微镜的瞄准系统必须设置分划板,才能实现对被测工件的瞄准测量。常见的分划板有:米字线,十字线,双夹线或其它形式的分划板等等。日常的测试工作中,首先根据不同的测量项目选择合理的分划板,即更换相应的瞄准目镜头,然后再对被测工件影像进行瞄准测量。 展开更多

AIM: To investigate histological characteristics of gastric polyps in the Korean population. METHODS: We reviewed endoscopic photographs and medical records of patients with gastric polyps who underwent endoscopic mucosal resection from April 1996 through February 2003. RESULTS: A total of 85 gastric polyps from 74 patients were reviewed, Male-to-female ratio was 1:1,96, Mean age was 59.9 =1:10,8 years. Multiple polyps were observed in 10,8%, Gastric polyps occurred most frequently in the antrum (58.8%), Pathological results on resected specimens were as follows: tubular adenoma 45.9%, hyperplastic polyp 31.8%, inflammatory polyp 9.4%, hamartoma 3.5%, fundic gland polyp 2.4%, tubulovillous adenoma 2.4%, adenocarcinoma 2.4%, dysplasia 1.1%, and mucosal pseudolipomatosis 1.1%. Discrepancy rate between endoscopic biopsy and pathology of resected specimens was 27.1%. There was no relationship between the size of the polyp and concordance rate. CONCLUSION: There is considerable discrepancy in histologic findings between endoscopic forceps biopsy and resected specimens. Approaches to review of the histology of an entire polyp should be performed, especially when an adenoma is suspected. 展开更多
