An Ancient Skeleton with Multiple Osteoblastic Bone Lesions Containing a Scapular Sunburst Appearance from a 5th?6th Century Grave Excavated in Oita, Japan

A human skeleton of a middle-aged adult male was found in a 5th-6th century Kinoue-Kodo stone coffin excavated from the southwest marginal region of the Oita plains, northeast Kyushu, Japan. The skeleton was buried respectfully in the ancient tomb, and red pigment was applied to his face after death. We report herein findings from computed tomography imaging of the skeleton and discuss the multiple osteoblastic lesions identified in the humerus, scapula, clavicle, vertebra, pelvic bones, and skull of this individual. These lesions comprised cortical bone thickening with periosteal reaction localized to the surface and osteosclerotic changes mainly observed in the trabecular structure of cancellous bone. In particular, a typical sunburst pattern was also noted on the left scapula as another characteristic lesion found in this case. By differential diagnosis, the disease suffered by this individual was most likely to be metastatic bone tumors, especially of prostate cancer. This person may have survived until many bone metastases had developed throughout his whole body

高速液体クロマトグラフィーによる血清中のトコフェロール同族体の蛍光定量の検討

The tocopherols in serum are determination by HPLC with fluorescent spectrometer. The results are as follows: 1. the filter of fluorescent specrometer for stable background exchanged 320nm for 300nm. Consequently the sensetivity was 62% up. 2. the recovery test of tocopherols were 88～92%. 3. the limit of dectection of α-tocopherols in the serum was 0.04μg. 4. the determination of tocopherols was able to make a small quantity of serum (0.08 ml)
