The purpose of the study was to investigate the early response of microvasculature, especially increased vascular permeability (IVP) to the light-continuous mechanical pressure stimulation. The hamster cheek pouch was used as an in vivo model of periodontal vasculature. FITC-dextran (molecular weight 150,000) was injected intravenously as a tracer and then intravital and electron microscopic observations were made and also the role of histamine in IVP to the mechanical stimulation was studied… CONTINUE READING
