title: Isolation and morphological features of primo vessels in rabbit lymph vessels.
abstract: Until now, even though intensive research has been dedicated to the primo vascular system (PVS) during these years, no statistical data on primo vessels and primo vessels in lymph flow have been available. Recently, the general morphological features of primo vessels in lymph vessels around the abdominal aorta were identified from microdissections of tissues from New Zealand White rabbits, and with Alcian blue staining, primo vessels in lymphatic vessels could be definitely identified under a digital microscope. The micro-dissected specimens in situ reveal rod-shaped nuclei stained by Acridine orange. The blue-stained nuclei, which were distributed in a broken-lined stripe, formed a tube structure of about 20 μm in diameter. The distance between the nuclei of two cells on neighboring aligned stripes, which is also the diameter of the micro tube, was measured to be about 5∼10 μm. The average length of the primo vessels was 2.4 mm, with the longest being 5.6 mm. The average size of the primo vessel was 50 μm, and the average diameters of the primo and the lymph vessels were 26.0 μm and 258.5 μm, respectively. Occasionally, without the use of Alcian blue staining, milk-white transparent primo vessels were observed floating in lymph vessels. Thus, we suggest that the PVS might also have an important function connected with the lymph system. We also expect the traditional Korean meridian system to leave its invisible world during the last thousands of years and soon enter the visible scientific world.
