@entity5123 ( @entity5123 ) of the salivary gland has diverse biological behavior in spite of its being a @entity5 . So the nuclear DNA content of 36 PAs was measured by flow cytometry to determine the relationship between proliferative activity and histopathological variable. DNA histograms were evaluated according to the rate of S and G2+ M phase cells (S + G2M%). We assumed that the DNA histogram measured algebraically, S + G2 M% < or = 0%, is the near diploid pattern and calculated its ratio to the near diploid pattern. A statistically significant difference between @entity5123 and normal salivary gland was found by the ratio to the near diploid pattern (P < 0.05), which confirmed the usefulness of the ratio to the near diploid pattern for measuring low proliferative activity. The @entity5 were divided into 3 groups: epitheloid type, intermediate type and myxochondroid type. In the 3 groups no differences were found by S + G2M% and the ratio to the near diploid pattern. The areas of the @entity5 were divided into 5 groups according to the ratio in the epitheloid region and the myxochondroid region. In the 5 groups, the area which consists partly of epitheloid components and mostly of myxochondroid components had the lowest ratio to the near diploid pattern and the highest S + G2M%, and the area which consists of only myxochondroid components had the highest ratio to the near diploid pattern and the lowest S + G2M%. Between only these two areas a statistically significant difference was found by the ratio to the near diploid pattern (P < 0.05). We considered that the area which consists partly of epitheloid components, and mostly of myxochondroid components has the highest proliferative activity in @entity5123 . Neither @entity2007 cells were found in any @entity5 , but the S + G2M% is more than 20% in 4 @entity5 . None of these high S + G2M% @entity5 except one recurrent @entity5 had clinical and histopathological features. A differences between PAs of the parotid glands and PAs of the submandibular glands was not found in S + G2M%.
