Abstract: Objective To explore a modified method of dyeing to improve the defect of Weigert's resorcinfuchsinstaining in incomplete staining of intimal elastic lamina.Methods Six segments of each elastic and muscular arteries were selected from the autopsycases of atherosclerosis in varying degrees. Routin paraffin section techniques and HE stain wereperformed on these tissues. Verhoeff method was applied to show elastic fibers in the arteriesinstead of Weigert's resorcin-fuchsin stain in the Movat pentachrome stain.Results Elastic fibers, proteoglycans, collagen fibers, smooth muscle fibers and, fibrin/red bloodcells were stained black, blue, yellow, red, and bright red respectively.Conclusion Modified Movat pentachrome stain can show both the artery structure andatherosclerotic plaque morphology more clearly.
