1984
Lee, Y.S. | Lim, C.H. (Seoul National Univ., Suwon (Korea R.). Coll of Veterinary Medicine)
An ultrastructural study was to investigate on 2 cases of canine leiomyosarcoma. The nuclei of most tumor cells showed bilobate appearance. Most cells of the tumors had no distinct basement membrane. Most cells of the tumors had a degenerative rough endoplasmic reticulum. Intercellular matrix contained some amounts of collagen. Attachment areas between tumor cells were not apparent, but a few tight junction were clearly seen. Myofibrils were present in bipolar end area

1984
Han, B.K. (Chonnam National Univ., Kwangju (Korea R.). Coll. of Agriculture. Dept. of Veterinary Medicine)
This study was to investigate the development pattern of epididymis in accordance with the growth of meat-type cockerels. Histological features of various ductules in epididymis of the cockerel on the age of weeks were within 10 weeks after hatching rete testis and connecting ductules were well developed but efferent ductules were observed in immature form. During 10th to 20th week, the lining epithelium of various ductules in epididymis was in the developing stage near to the mature form

1984
Lee, H.S. | Lee, J.S. (Seoul National Univ., Suwon (Korea R.). Coll. of Veterinary Medicine)
This macroscopic observation was performed to investigate the aortic arch and their branches of the Korean native goat. Ten Korean native goats with black hairs ranging in body weight from 15 to 20kg were used. The findings were based on the latex cast of the vessels made by injection of neoprene latex. The Truncus bicaroticus was continued from the Truncus brachiocephalicus after branching off the A. subclavia dextra in 8 out of 10 cases, but the As. carotidas communes sinistra and dextra were directly branched from the Truncus brachiocephalicus without forming the Truncus bicaroticus in the remaining 2 cases
