Abstract

Improved techniques were developed for processing inflammatory skin lesions in glycol methacrylate (JB-4, Polysciences, Inc.) and for quantitating their leukocyte infiltrates by light microscopy: (1) fixation of entire pelts from rabbits, guinea pigs, rats and mice bearing multiple lesions eliminated artifacts due to biopsy and produced uniformly oriented skin sections; (2) adding dimethylsulfoxide and hydrogen peroxide to the Karnovsky-type fixative increased the rate and effectiveness of fixation; (3) the presence of glycerol in the infiltrating methacrylate and the polymerized plastic block improved the sectionability of skin and other tissues; (4) coating slides with JB-4 Solution A prevented detachment of specimens; (5) Giemsa staining at a carefully selected pH provided optimal differentiation of leukocytes from the several species examined, including man. These techniques, which allowed an accurate histologic assessment of inflammatory skin lesions, were especially valuable for quantitating basophils.
