Accessory Renal Arteries Found during Dissection / 체질인류학회지

Accessory renal artery (ARA) is a kind of developmental anomaly in renal artery. It is important in respect to clinical medicine, for example primary hypertension, renovascular disease, inferior vena caval obstruction, ureteral obstruction, occurrence of other vascular anomalies such as accessory renal veins, surgical importance and renal transplantation. However, up to few research of ARA was reported in dissection of cadavers. In our dissecting theater, 12 accessory renal arteries for 10 cadavers were found during dissection the 22 cadavers from 1995 to 1996. 1. Two cases were bilateral and 8 cases were unilateral accessory renal arteries. 2. Seven cases were left and 5 cases were right accessory renal arteries. 3. Two cases originated at the abdominal aorta between celiac trunk and superior mesenteric artery, 7 cases originated between superior mesenteric artery and inferior mesenteric artery, and 3 cases originated below inferior mesenteric artery. 4. Seven cases have no branches during their courses, 4 cases have 3 branches, and a case has 2 branches. 5. Seven cases entered into renal parenchyma through renal hilum, 5 cases entered into apical and arterosuperior segments, and 6 cases entered into inferior segment.

Permanent Preserving the Bony Fragments Digged Up from Haemi Nameless Martyrdom Holy Place Burial Sites / 체질인류학회지

Bone materials diggd up from the Haemi nameless martyrdom holy place burial sites were severely broken into fragments of various size, clay matrix filled the bone marrow cavities, grass roots were spreaded into the periosteum and the fragments were very soft enough to be flaken. To make permanent specimens, bony fragments impregnated within unsaturated polyester resin with catalyzer MEKP, promotor 8% cobalt octoate, and UV absorber. Permanent specimens were so very transparent that all the macroscopic structures can be observed, and they were hard enough not to be broken or cracked. This method of preserving bony fragments is considered to be used in archaeologic preservation and in making teaching materials of various human organs or tissues.
