title: [Quantitative studies of mast cell proliferation at the wound edge --rate of DNA synthesis in intravital and postmortem biopsy].
abstract: The number of DNA synthesizing mast cells in experimental induced wounds was calculated using bromodeoxyuridine as a DNA marker and naphthol AS-D chloroacetate esterase as a mast cell marker. After different survival times, specimens of the wound edge were taken before death and 24 hs after death. At a survival time of 48 hs in vital biopsy the number of DNA synthesizing mast cells peaked, at 72 hs and fell after a period of 8 days. Even though an identical kinetic course was demonstrable in cases of postmortal biopsies the percentage at each survival period was significantly lower than in vital biopsies.
