The cytofluorometric nuclear DNA ploidy analysis was performed in gallbladder (GB) epithelium of eight patients of chronic cholecystitis to make a comparison between fresh and paraffin embedded tissue analysis, to make an ideal single cellular suspension, to evaluate the ploidy pattern affected by inflammation and to assess the histological correlations. Six (75%) fresh specimens and eight (100%) paraffin embedded specimens showed diploidy pattern of histogram. Two (25%) fresh specimens showed low ploidy pattern of histogram. There was a good correlation between histological findings and the ploidy patterns of 100% paraffin embedded specimens and 75% fresh specimens. The relative fluorescence intensity was found higher and more stable in paraffin embedded tissues than fresh tissues. Inflammation did not affect the ploidy patterns of paraffin embedded specimens whereas the ploidy patterns of fresh specimens were affected. It can be concluded that the DNA ploidy patterns and histological findings have a good correlation and inflammation does not affect the cytofluorometric DNA ploidy pattern when using the paraffin embedded specimens. Paraffin embedded specimens are superior to fresh specimens for making an ideal single cellular suspension to obtain stable, high, and accurate fluorescence intensity with less background fluorescence which makes the ploidy pattern behave like exact behavior of tissues.
