OBJECTIVE To investigate the structure and function of the venous valve agger, a fibroelastic structure located at the base of every valve in veins that are responsive to noradrenaline (NA). DESIGN Constant flow perfusion studies of the responses of in situ and in vitro canine lateral saphenous vein segments to NA and electrical stimulation, supplemented by histological studies of the segments. SETTING University Departments of Physiology and Histology. MATERIALS Segments of canine… CONTINUE READING
