| 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 | Ferrous Iron-induced Lipid Peroxidation in Cell Culture: preliminary experiments |
| FullText URL | 003_049_053.pdf |
| Author | Yamamoto, Goki| |
| Abstract | To study the effect of Fe(2+) on the cell culture, preliminary experiments related to the lipid peroxidations of 3T3 cells and calf serum were carried out. Amonuts of lipid peroxides, as thiobarbituric acid (TBA)-reactive substances, were measured by means of the TBA color reaction under the acidic conditions by acetic acid, and were expressed as TBA value. The TBA value of calf serum in the phosphate buffered saline (PBS) with ethyrendiaminetetraacetate (EDTA) was lower than that of the control. The value in the presence of Fe(2+) showed significantly high level, but it was almost prevented by the addition of EDTA. Besides, Fe(2+)-induced lipid peroxides of serum in the PBS during the incubation at 37℃ were capable to measure by the application of EDTA. The TBA values of trichloroacetic acid (TCA) precipitates isolated from serum in the PBS and the culture medium were lower than that of control serum, but no difference was observed between the both TCA precipitates. The results suggested that the impurities in the culture medium were removed by TCA precipitation. Effects of Fe(2+) and EDTA on the TBA value of TCA precipitates were observed similarly to the case of control serum. Fe(2+)-induced lipid peroxidation of the cells in the PBS, which the peroxidation was stopped by the addition of EDTA, was observed, and it was accompanied with the lag time of induction period. The TBA value of the cells was more prevented by EDTA. The method in this paper may not be capable for the quantitative measurements of lipid peroxides in cells or serum, but is applicapable to measure the changes of relative amounts of lipid peroxides. |

| Title Alternative | Measurement of Fe(2+)-induced Lipid Peroxidation of Mitochondria used Thiobarbituric Acid Method under the Acetic Acid Conditions |
| FullText URL | 003_043_047.pdf |
| Author | Yamamoto, Goki| |
| Abstract | Mitochondrial lipid peroxidations were usually detected by the thiobarbituric acid (TBA) color reaction under the acidic conditions with hydrochloric and trichloroacetic acids. The time response curve of Fe(2+)-induced lipid peroxidation, accompanied the lag time of induction period, of mouse liver mitochondria was measured with detection of the produced lipid peroxides by the TBA method under the acidic conditions with acetic acid. Fe(2+)-induced lipid peroxidation was terminated by the addition of ethylenediaminetetraacetate (EDTA). The lag time of the peroxidation detected by TBA method in the acetic acid conditions was obtained as well as that detected in the hydrochloric and trichloroacetic acids conditions. The fact indicates that Fe(2+)-induced lipid peroxidation of mitochondria and its lipid peroxides are able to be measured by the TBA color reaction in the acetic acid conditions with EDTA. |

| Title Alternative | Measurement of Serum Lipid Peroxides used Thiobarbituric Acid Method: Colorimetric and Fluorometric Assays and Effect of Ferrous Ion |
| FullText URL | 002_051_061.pdf |
| Author | Yamamoto, Goki| |
| Abstract | Serum lipid peroxides were measured by a thiobarbituric acid (TBA) method. TBA color reactions carried out under the conditions with acetic acid (TBA-AA) or hydrochloric acid (TBA-HCl) systems, and then TBA value was detected by colorimetric ([OD]) and fluorometric ([FR]) measurements. Effects of ferrous ion, ferric ion and EDTA on the both systems were examined. Equal TBA value dependent upon concentrations of MDA (tetraethoxypropane) were obtained on both systems detected by [OD], but the relative fluorescence of TBA-AA system was higher than that of TBA-HCl system. Fluorometric determination was suitable for low TBA value, and colorimetric one was for high TBA value. Good correlation between TBA[OD] values and TBA[FR] values of serum from patients was estimated, but it was suggested that effects of serum substance were differ on the both systems. Effects of iron on TBA-AA and TBA-HCl systems were different significantly, particularly high Fe-TBA values obtained from TBA-AA system in the presence of ferrous ion. The fact suggests that serum lipid peroxidation is induced by ferrous ion during a heating of TBA color reaction. Same effect of ferric ion in TBA-AA system was observed. The increment of TBA values by ferrous and ferric ions was inhibited by a addition of EDTA. It was considered that the difference effect of iron on the both systems was due to pH and acetic acid concentration. The relationship of TBA values and Fe-TBA values of serum from patients was no correlated, and the various inhibition ratios of EDTA for the TBA value was calculated. It is suggested that Fe-TBA value is possible to detemine the qualitative difference of serum lipid peroxides. |

| Title Alternative | Lipid Peroxides (TBA reactive substances)and Fatty Acid Compositions in Mouse Serum with Whole-body Irradiation and in Tumor-bearing Mouse Serum with Local Irradiation |

| Abstract | Effects of irradiation on lipid peroxides of mouse serum, Ehrlich solid tumor-bearing mouse serum, which tomor cells were transplanted to the leg, and its tumor tissue were studied by a thiobarbituric acid (TBA) color reaction in the acetic acid condition with (Fe-TBA value) or without (TBA value) ferrous ammonium sulfate. TBA reactive substances were caluculated into the amount of malondialdehyde. Besides, fatty acid and lipid compositions were analyzed as a substrates. Irradiated samples were isolated at 3 days after irradiations. The TBA value of normal mouse serum was expressed 17nmoles/ml of serum, and Fe-TBA value gave 2.4-fold of the TBA value. Although an increase TBA value was not observed by whole-body irradiation, a significant increase of Fe-TBA value was measured, indicating 2.5-fold at 10Gy exposure compared with the normal Fe-TBA value, and 5.5-fold with the TBA value. The TBA value of tumor-bearing mouse serum was 14nmoles/ml as a low rate to that of normal serum, but the Fe-TBA value gave same magnification of that of normal one. The TBA value of tumor-bearing mouse serum was not changed by the local irradiation to the tumor region of leg, but the Fe-TBA value was increased 2.8 and 4.4 times at 10Gy and 20Gy exposures, respectively, comparing with the non-irradiated one, and 7.7 and 10.5 times with the TBA value, respectively. The TBA value of solid tumor homogenate exhibited 1.16nmoles/mg of protein, and the Fe-TBA value, pointed out 5 times as much as the TBA value. Both values slightly increased by the irradiation. These facts suggest that a shift of TBA value of serum hard to get, but Fe-TBA value of serum distinctly increases by the irradiation. The fatty acid composition of mouse serum lipids showed an increment of relative percentages of linoleic and arachidonic acids by the whole-body irradiation. The relative percentage of fatty acid compositon of lipids from solid tumor-bearing mouse serum was similar tendency to that of normal one, and the local exposure to the tumor part was not affected the each percentage. The percentage of high unsaturated fatty acid of tumor lipids similar to that of serum lipids, and a decrease of the percentage of arachidonic acid was accounted by the irradiation. In relative percentages of lipid compositions, the percentage of choleste rolester of serum lipids increased by the whole-body irradiation, and that of phospholipid fraction was not changed. In the case of tumor-bearing mouse serum lipids, an increment of the percentage of cholesterolester was obtained as compared with that of normal serum lipids, and this percentage decreased by the local irradiation to tumor part with an increment of the percentage of phospholipid. The percentage of phospholipid in tumor lipids had decreased by the irradiation. The facts suggest that a cause of the increased Fe-TBA value of tumor-bearing mouse serum by the irradiation to tumor is due to the release of peroxidizable phospholipid into serum from the damaged menbranes of tumor cells at large doses to exposure. |

| Abstract | A modelling of interface construction relating to power-line interference phenomenon was described. Source of interference was displacement currents which flowed from AC power-line configuration (APC) to a model. The interference depends on some factors: distance between the APC and a model ; length of unshielded leads ; position of the APC in vertical or horizontal direction ; and skin-electrode impedances which were balance or unbalanced. The position of APC and skin-electrode impedances were important in contributing of the interference. The interference was still large even though skin-electrode impedances were balance. This was caused by the disagreement in two displacement currents. It was overcame by adjustment of APC in vertical direction. As a result, total interference would be very small or zero. The result shows that interference in ECG signal recording can be eliminated to about 10 μV. Although interference of power-lines is a complicated phenomenon, the problem is easier to understand by using this modelling. |

| Author | Nakamura, Takao| Yamamoto, Yoshitake| |
| Abstract | これまでに生体電気インピーダンスを用いて身体運動の解析を行ってきた。インピーダンスの変動原因は測定部位の等価断面積変化および貯血量変化と説明できるが，直接的に断面積変化や貯血量変化を測定することは困難であるため，その変動原因の定量的な検討は不十分であった。そこで，本研究では上肢運動に伴う生体電気インピーダンスの変動原因を生体の等価回路のパラメータの変動で説明する。インピーダンスのモデルはCole－Cole型であり，等価回路は，細胞外液抵抗Re，細胞内液抵抗Ri，分散の特性周波fm fm，緩和時間の分布の程度を表すα，βの独立した5パラメータで表現した。 上肢の肘関節および手関節の屈曲運動野に伴う前腕部および上腕部の電気インピーダンスを測定した。まず，電気インピーダンスの等価直列抵抗Rの変動率をパラメータの変動率で線形近似し，その信頼性と各パラメータ変動のRへの影響を確認した。Rへの影響はReとRiが支配的であるが，測定部位や運動の違いにより，それぞれの影響が異なることを示した。これは測定部位の筋活動状態の違いを表すものである。さらに，肘関節最大屈曲におけるRの変化にはfmの変化が大きく依存しており，上肢運動のインピーダンス変化には細胞膜の分極特性の変化も影響していることを明らかにした。本研究の結果は，運動強度の違いや疲労状態における身体運動評価に有意義である。 |

| Abstract | 流動する血液についての力学的，光学的および電気的な特性についての研究が数多く報告されている。本研究では，狭窄がある人工血管を流れる血液の電気インピーダンス（周波数10kHz）を近赤外光（波長940nm）の透過度と同時に測定し，血液の電気インピーダンスの特性について検討を行った。内径2mmのアクリル製の血管モデルを作製し，その内部に断面積の小さい狭窄部位を1ヵ所設置し，ヒトの血液（Hct40％）を流した。定常流においては血流速度の増加に伴いインピーダンスの相対変化量および透過光強度ともに減少した。しかし，狭窄部に近い部位では，インピーダンスと透過光強度の変化パターンに違いがみられた。インピーダンスおよび透過光強度は流動する血球の動きや配向等を反映していると考えられた。 |

| Abstract | The effects of aluminum (Al) on the cytotoxicity of ferrous iron (Fe(Ⅱ)), copper(Cu) and cadmium(Cd) were studied. Log-phase cells were treated with either FeSO4,CuSO4, or CdCl2 in the presence or absence of AlCl3(120μM) for 18h at pH 4.0. After the treatment, the viability was determined as relative growth of the metal-treated cells to the untreated control cells during the post-treated culture. A single treated with either Al, Fe(Ⅱ) or Cd did not inhibit the growth at the metal concerntrations up to 300 μM, 200 μM and 500 μM, respectively, whereas the growth was markedly inhibited at 15 μM Cu. Thus,the cells were relatively insensitive to Al, Fe(Ⅱ) and Cd and sensitive to Cu. When cells were treated with both Fe(Ⅱ)(120 μM)and Al(120μM), the growth was significantly inhibited and the cellular contents of both Al and Fe increased synergistically. After the treatment with Cu(0 to 10 μM) with or without Al, the cells grew more vigorously when they were treated in the presence of Al, althrouh the Cu content of the cells were not alterd by Al. The presence of Al during the treatmemt with Cd(0 to 2 μM) had no effect on the degree of growth inhibition by Cd. Thus, Al interacts with the toxicity of Fe(Ⅱ), Cu and Cd in different manners; synergistic with Fe(Ⅱ), antagonistic with Cu and apparently no effeco on Cd. |
