We have isolated various types of Bonghan ducts. Mostly they consist of a bundle of tubules with fiber-like striae. Bonghan duct isolated from peritonea shows the presence of very large rod shaped cells whose length is almost 50um inside the tubules. Bonghan duct isolated from human umbilical cord also shows the presence large cells at the end section of the tublules, which are of more round shapes. However, sometimes very narrow lines of small granules whose size is about lum were also observed from various types of Bonghan ducts. The electron microscopic examination(TEM) could confirm the existence of the small granules inside the striae forming the tubule, suggesting the striae might be also unique tubular structures. TEM showed that the granules inside striae have the nucleus and the membrane, and even divide. Present investigation reveals that there exist different levels of tubular structures inside Bonghan duct, and further suggests the granules and the cells inside each tubular structures might be intercon verted.
