Morphometric analysis of lymphatic vessels in primary biliary cirrhosis.

The purpose of this study was to elucidate the morphometric changes occurring in hepatic lymphatics in primary biliary cirrhosis (PBC). The lymphatic vessels were stained intensely by enzyme-histochemistry for 5'-nucleotidase while blood vessels stained well for alkaline phosphatase (ALP). We performed a morphometric analysis to estimate the number of lymphatic and blood vessels and their areas, using computer graphics software (NIH Image).
