“…After the early confirmation by Fujiwara and Yu (23), the threadlike structures inside blood vessels were observed in animals such as rabbits (24), rats (25) and pigs (26). Those on the surfaces of the internal organs of rabbits and rats were also observed (13,27).…”

A novel application of fluorescent magnetic nanoparticles was made to visualize a new tissue which had not been detectable by using simple stereomicroscopes. This unfamiliar threadlike structure inside the lymphatic vessels of rats was demonstrated in vivo by injecting nanoparticles into lymph nodes and applying magnetic fields on the collecting lymph vessels so that the nanoparticles were taken up by the threadlike structures. Confocal laser scanning microscope images of cryosectioned specimens exhibited that the nanoparticles were absorbed more strongly by the threadlike structure than by the lymphatic vessels. Further examination using a transmission electron microscope revealed that the nanoparticles had been captured between the reticular fibers in the extracellular matrix of the threadlike structures. The emerging technology of nanoparticles not only allows the extremely elusive threadlike structures to be visualized but also is expected to provide a magnetically controllable means to investigate their physiological functions.

“…1 These systems, which provide important materials for development, including oxygen and nourishment, tremendously affect every step of embryonic development. The primo-vascular system (PVS) was recently reported as an additional circulatory system that is present in bovine hearts, 2 rabbits, 3 rats, 4 and mice. 5 The PVS has also been found in plants, 6 which suggests a primitive role of the PVS in living organisms.…”

The two major circulatory systems, the lymph system and the blood vessel system, play significant roles in controlling embryonic development. The primo-vascular system (PVS) was recently reported as an additional circulatory system in various animals. In this paper, the PVS in a mouse embryo was investigated. The structural characterization of the PVS in the mouse placenta and umbilical cord, which was visualized with the trypan blue staining technique, was focused on. The PVS was well_developed in the mouse placenta area. Using a nanopore-based amperometric oxygen sensor, the oxygen levels at four different areas of the embryonic brain, placenta, blood vessel, and primo-vessel of the PVS were measured. The relatively higher oxygen levels that were measured at the primo-vessels than at the brain and the placenta, while still lower than the oxygen level that was measured at the blood vessels, may suggest a role of PVS in oxygen transport.

“…The superficial BH corpuscles and ducts were parts of a circulatroty system which was consisted of several subsystems: superficial BH system in the skin, intravasculat BH system inside large blood and lymphatic vessels, and organsurface BH system on the surfaces of various internal organs. The intravascular BH ducts inside blood vessels were confirmed by using an acridineorange staining method 6,7) , and those inside lymphatic vessels were observed employing a Janus Green B staining technique 8) as well as a nanoparticle injection method 9,10) .…”

Objective In this article, we report on the intradermal Alcian blue staining method for tracing the meridians of acupuncture. Methods 1% Alcian blue solution was injected into acupoints by using a 0.5mL insulin syringe with a 31-gauge needle, then the skin was incised and was observed under a stereoscopic microscope. The specimens were examined by using immunohistochemical methods and were observed under a confocal laser scanning microscope. Results A threadlike structure, which was visualized with Alcian blue, existed in dermis layer and proceeded to hypodermis. In this structure, characteristic alignments of rod-shaped nuclei and 1-2μ m sized DNA granules were observed. Furthermore, abundant blood capillary plexuses, peripheral nerve endings, and a corpusclelike structure(about 300μ m in diameter) were visualized in the skin tissues of acupoints. Conclusion It was concluded that the specific threadlike and corpuscle-like structures corresponded to superficial Bonghan duct and corpuscle, respectively.
