The Differential Diagnostic Role of Nuclear DNA Contents in Gastric Cytology

摘要: Cytologicyl material from the stomach was formerly obtained by gastric washings or cell-swab-sounding. Using these methods we obtain exfoliated cells that have been in a hydrochloric milieu for longer time. The acid effects prehydrolysis of nucleoprotein complex cell nuclei, thereby rendering impossible exact cytophotometric measurements. After introduction fiberglass endoscopy it has become possible to vivo fresh cytological which is suitable DNA determination. In analogy cervical cytology, possibility associating cytomorphological findings with characteristic frequency distribution patterns investigated. addition, question raised whether flow-through nuclear determination can be used diagnosis carcinoma.
