| Abstract | Tomography is clinically useful in the diagnosis of the temporomandibular joint (TMJ) syndrome. The TMJ is formed by the condyle and the glenoid fossa, and there exists TMJ space between them. Image processing was employed in the present study, and the reference points of the condyle and the glenoid fossa were determined from the tomogram. Subsequently, the TMJ space was measured automatically in the image analysis. The TMJs of 98 patients were examined practically and the characteristics of each result were studied. There is a possibility of discriminating an abnormal condylar position from a normal one by making use of the TMJ space and the distance between two reference points. |

| Title Alternative | Dosimetry in Radiography |
| FullText URL | 004_069_073.pdf |
| Author | Nakagiri, Yoshitada| Goto, Sachiko| Mikami, Yasutaka| Azuma, Yoshiharu| Sibuya, Koichi| Inamura, Keiji| Tahara, Seiji| Uno, Hirohumi| Takata, Yoshiaki| Tandani, Nobuyoshi| Yamada, Toshiharu| Sugita, Katsuhiko| Hiraki, Yoshio| |
| Abstract | Utilization of radiation in medical treatment is increasing more and more ; consequently, It becomes more important to estimate exposure dose correctly. Altough there are many reports about exposue dose for patients, most of them merely describe the results of the measurements by parts of the body. Exposure dose differs with equipment, instruments, screen-firm system, contition of radiography, and so on. This paper describes the relation between skin dose and contitions of radiography, and also shows the result of measurement of "TPR" which needs to know the absorbed dose of each organ. |

| Title Alternative | Ferrous Iron-induced Lipid Peroxidation in Cell Culture: Effects of Ferrous and Ferric Irons on Cell Survival and Serum Lipid Peroxide |
| FullText URL | 004_061_068.pdf |
| Author | Yamamoto, Goki| |
| Abstract | Cell killing activities of ferrous and ferric irons (Fe(2+), Fe(3+)) in cultured 3T3 cells were investigated by the colony forming method in the culture medium containing 10% calf serum. In the colony forming method, small isolated colonies are seen in the dish which are the resulted of individual cells having undergone a series of cell divisions. Survival curve for Fe(2+)-induced loss of reproductive capacity (cell death) in 3T3 cells, showed a shoulder at low concentrations and only became exponential at high concentrations. Cells affected at 0.05mM Fe(2+) underwent apparently normal cell divisions, but at a much slower rate than the control. Survival rate at 0.5mM Fe(2+), which iron was added after seeding cells (added group), showed 0.75% but that at 0.5mM Fe(3+) did 19.3%. From the determination of Fe(2+) content carried out by the colorimetric method used N-PSAP, the oxidation of Fe(2+) was seen rapidly after adding Fe(2+) into the culture medium. In the cases of cells seeded 3 hours after adding Fe(2+) or Fe(3+) (preadded group), the survival rates showed much lower than those of the added groups, that is 55% at 0.5mM Fe(2+) and 89% at 0.5mM Fe(3+). The facts suggest that the radical reactions iniciated by the oxidation of Fe(2+) under the presence of cells, occured just after adding Fe(2+), play a crucial role in the damages on the adhesion of cells onto the dish and the following proliferation of cells. Serum lipid peroxides, as thiobarbituric acid reactive substances (TBA value), of the final cultured medium at colony counting time were measured. In the Fe(2+) added group, the TBA values more increased in proportion to the added concentrations of Fe(2+), whereas in the Fe(3+) added group, the increments of TBA values were very slightly and not to be depended on the concentrations. Furthermore, the TBA values of the Fe(2+) or Fe(3+) preadded groups were estimated as well as those of the added groups, respectively. The facts suggest that serum lipid peroxides induced by Fe(2+) have little effect on the proliferation capacity of cells in the level of cell culture. |

| Title Alternative | Estimation of balium preparations with high density and low viscosity |
| FullText URL | 004_057_060.pdf |
| Author | Shibuya, Koichi| Kobashi, Takao| Ogasawara, Mitsuo| Tandani, Nobuyoshi| Nakagiri, Yoshitada| Azuma, Yoshiharu| Sugita, Katsuhiko| |
| Abstract | In this paper we compared the balium preparations having high density and low viscosity (BP-HDLV) with those currently in use. We adopted the stomaches of pigs and the new phantom manufactured by ourselves. We especialy noted the quality of the contrast. The results indicate that BP-HDLV do not always make high contrast. The contrast is related to fluidity besides density. The fluidity of BP-HDLV should be improved. In adition, it costs much to increase content of balium. Therefore, we can not find out positive significance to use these BP-HDLV. |

| Title Alternative | Clearance study of polyethylene glycol-modified cholesterol esterase. |
| FullText URL | 004_053_055.pdf |
| Author | Mori, Shuji| Nakata, Yasunari| Endo, Hiroshi| |
| Abstract | The clearance of polyethylene glycol-modified cholesterol esterase was investigated spectrophotometrically, as compared with native one. PEG-modification provided the significant elongation in clearance time of cholesterol esterase after intravenous injection in mouse. This method was shown to be effective for creating new biomaterials. |

| Title Alternative | IgG Heavy-Chain Subclass Typing of Human Serum M-Protein -Optimal condition for the separation and the detection with high resolution of agarose gel isoelectrofocusing- |
| FullText URL | 004_047_051.pdf |
| Author | Ichimura, Mitsuko| Tohge, Hiroko| Sakiyama, Junko| Nakata, Yasunari| Endo, Hiroshi| |
| Abstract | IgG Heavy-Chain subclass typing of human serum M-protein were isoelectrofocussed (IEF) in agarose gel, and then the bands of IgG were detected with peroxidase-conjugated anti-human IgG1-4 monoclonal antibodies on the same isoelectrofocussed agarose gel plate. This IEF enzyme immunodetection patterns were composed of four to eight discrete bands (The range of pI was 6.0 to 9.0). These bands were dependent on immunofixationbands. It was very specific and clear to detect the subclass of IgG Type M-protein in human serum using this method. |

| Abstract | 神経生物学的研究における基本的分析系の確立を目的として、シクロデキストリン（CD）を用いたラット大脳皮質神経細胞の初代培養を試みた。β-およびγ-CDは、無血清培地（ダルベッコ改変MEM/ハム培地）中で胎生16および18日目ラットの神経細胞を11日以上10％胎児ウシ血清を加えた培地中と同じ程度に生存させたが、α-CDには生存維持効果が無かった。β-CDはγ-CDより安定した生存維持効果を示したが、胎生21日目ラットの神経細胞を用いた場合は有意に生存率が低下し、新生児ラットでは生存維持効果が無かった。β-CDを用いた無血清培養では10％血清培地中と比べて神経突起の伸展が悪かったが、ときに顕著な突起伸展がみられ、これはCD分子に取り込まれた生理活性物質の作用と考えられた。また、β-CDを用いた無血清培養を利用してラット脳から精製したコンドロイチン硫酸プロテオグリカン（CSPG）の作用を検討し、CSPGがグルタミン酸による神経細胞死を防止すること、弱いながら培養神経細胞の生存を維持する作用をもつことを示した。以上の結果から、この無血清培養法は神経生物学的研究において有用な分析系となりうることを指摘した。 |
