Abstract:
A study the quantitative measurement of DNA content in 3 normal lacrimal glands, 18 pleo-morphie adcnomas and 21 lacrimal gland carcinomas was carried out by flow eytometry. The results showed that pleomorphie adenomas still had the characteristics of DNA content of the normal diploid lacrimal gland cells. The significant increase of DNA index (DI) in pleomorphie adenomas might mean malignant transformation. DNA content of malignant tumor increased evidently and its aneuploid ratio was higher than in pleomorphic adenomas (76.2% VS 16.8%) (P
