&emsp;Forensic biologists are increasingly likely to identify an individual using three-dimensional imaging equipment. Existing equipment requires taking the subjects to the place where the equipment is located. In recent years, a non-contact, hand-held three-dimensional color scanner has been developed that is compact and lightweight. Therefore, we already use it for facial recognition and cranio-facial superimposition. The three-dimensional scanner reconstructed skull images precisely, and the anthropological measurements obtained from the images were comparable to those obtained from actual skulls (the differences in measurements were less than 1mm). Furthermore, the skull images produced by the scanner corresponded with high accuracy to the three-dimensional images reconstructed using computed tomography (concordance rates were approximately 95%) and to the two-dimensional facial photographs of the same person (the differences were less than the standard value 2.5mm for the reciprocal point-to-point matching). In addition to the skull images, the three-dimensional scanner precisely reconstructed facial images of living people. The three-dimensional facial images approximately corresponded to the two-dimensional facial photographs of the same people taken from both the vertical direction and from a bird's-eye view (the difference were less than the standard values, 0.9mm for the outline matching and 2.5mm for the reciprocal point-to-point matching). In conclusion, the current study confirmed that the non-contact, hand-held three-dimensional color scanner can provide forensic biologists with precise three-dimensional images of both skulls and living people's faces and that the images are of sufficiently good quality to be put to practical use as the quality of conventional stationary type.<br>

豚血液の生化学成分の測定について血清を用いた場合と血漿を用いた場合の濃度差を比較し, あわせてそれぞれの溶血傾向について検討し, 以下の成績を得た。溶血程度を吸光度測定 (日豚会誌. 25. 1988) で比較し, 血清および血漿の溶血程度を区分した場合, 血清では-が53.3%, ±が33.3%, +が6.7%, ++が6.7%を占めたのに対し, 血漿では-が46.6%, ±が16.7%, +が20.0%, ++が16.7%を占めた。生化学成分の測定値について血清と血漿を比較した結果, 血清と血漿で差がないものとしてAlb, BUN, Na, K, Cl, ALP, CPK, GPT, LDH, Glu, T-chol および Tri-G があげられ, 差があるものとしてTP, T-bil, Cre, Ca, GGTおよびGOTがあげられた。血清と血漿の測定値で差があった項目について, 相関をみると, すべての項目について, 両者の間には有意な相関が成立した。さらに, 相関係数が0.7以上, 回帰係数が0.7~1.2の範囲のものとしては, TPおよびCaがあげられた。
