Conference paper


We report the structure of sinuses in the primo vessels on the surfaces of endocardia of atriums and ventricles in the bovine heart. About 1–5 sinuses (0.5–7 μm in diameter) were observed in the cross sections of the primo vessels (20–50 μm in diameter). The boundary of the sinus was clear and was regularly surrounded mainly by collagenous fibers (∼30 nm in diameter) and partly by 1–2 cells.

This work was supported by a Systems Biology Infrastructure Establishment grant provided by the Gwangju Institute of Science and Technology in 2010 and by the Association of Korean Oriental Medicine. Electron microscopy was supported by staff scientists in the National Instrumentation Center for Environmental Management. We appreciate Mr. Jin-Gyoum Kim at the National Agricultural Cooperative Federation of Korea in Bucheon for kindly providing the bovine hearts.
