STUDY FOR DEVELOPMENT OF ULTRA-HIGH MAGNIFYING FIBERGASTROSCOPE

Abstract

Ultra-high magnifying fibergastroscopes were developed for the purpose to observe the cells and nuclei of stomach endoscopically. At first, rat's gastric mucosa was observed under 170× magnifications (Figure 2, 3) using rigid ultra-high magnifying fiberoptics(Figure 1). For clinical application, mother and child type ultra-high magnifying fibergastroscopes were developed (Figure 4). Epitherial cells which absorbed methylene blue were observed clearly using this instrument (Figure 5, 6).
