Abstract

SOD in red cells is generally expressed in terms of the ratio to hemoglobin content. However, it is widely distributed and reacts within the water of erythrocytes. Therefore, it is more reasonable to express SOD in terms of the ratio to water content. No report has appeared, however, on expressing the ratio of SOD to water contect of erythrocytes, because of inherent disadvantages of the conventional method to determine water content of red cells. A new method was reported based on gas-liquid chromatography (GLC), for rapid and precise measurement of water content in red cells and plasma. Using this method, it is the purpose of the present report to provide valid reasons for expressing the ratio of SOD to water content of erythrocytes instead of hemoglobin. The authors found SOD expressed in terms of terms of the ratio to water content with greater accuracy and better validity than that in terms of the ratio to hemoglobin., 最近話題になっている活性酸素は運動によっても発生し溶血性貧血に関係していると考えられる。そこで赤血球のSOD活性を測定し運動による活性酸素の発生状態を検討し赤血球の浸透圧抵抗に及ぼす影響について実験研究を試みるために従来のSOD活性測定のヘモグロビン1mg当たりの表記にかえて赤血球中の水分1mg当たりの活性酸素量を測定することの妥当性について検討した。SOD活性を水分1mgあたりで表現した場合ヘモグロビン1mgあたりと比較として再現性がすぐれて居り高張食塩水,生理食塩水,低張食塩水の順にSOD活性の値が高く,これは理論と合致し運動生理学への応用が期待される。

Abstract

The purpose of this study was to develop an age scale for assessing activities of daily living (ADL) among community-dwelling adults aged 75 years or older. Participants were 1006 older Japanese: 312 men (79.6 ± 4.3 years) and 694 women, (79.9 ± 5.5 years). Participants completed a battery of 8 performance tests related to ADL and the Barthel index (BI) questionnaire. Spearman rank-order correlation analysis was applied to obtain the correlation of the 8 ADL performance tests with the total BI score. Three variables were high rank-order correlated with BI, secondly those items were subjected to the principal component analysis. The weighted combination of the principal component scores was summed. Resulting in an ADL score (ADLS), women = 0.075 X1 – 0.082 X2 – 0.063 X3 + 0.124, men = 0.051 X1 – 0.105 X2 – 0.099 X3 + 0.249, where X1 = hand-grip strength, X2 = timed up and go, X3 = five-chair sit to stand. Individual ADLS was transformed to an ADL age scale (ADLA). The estimation was – 5.493 ADLS + 79.90 for women, and – 4.272 ADLS + 79.57 for men. Due to the distortion at the regression edges, the equation was corrected as suggested by Dubina et al. ADLA women after correction was = 0.447 (chronological age: CA) – 5.49ADLS + 44.17, men = 0.519CA – 4.27ADLS + 38.26. ADLA can be used to identify or monitor the characteristics of the ADL levels of physical abilities in older Japanese aged 75 years or older.

Abstract

Objective: There are few studies testing the accuracy of bioelectrical impedance analysis (BIA) as a method for detecting body composition in older adults, including the pre-frail. This study compares body composition measured with BIA and dual X-ray absorptiometry (DXA) in non-frail and pre-frail older adults. Methods: We recruited 166 participants including 60 older adults (75.0 ± 5.7 years, 65-88 years, 41 women and 19 men) classified, according to Fried's definition, as non-frail (34 older adults, 74.5 ± 6.6 years) and pre-frail (26 older adults, 75.5 ± 4.5 years). Fat mass (FM) and fat-free mass (FFM) were estimated by DXA (DPX-LIQ, GE Healthcare) and BIA (MC-190, Tanita, Japan). We also compared this data with 106 healthy adults (39.4 ± 12.4 years, 20-64 years, 55 men and 51 women). Results: There were no differences between BIA and DXA results for FM in the non-frail and FFM in the pre-frail. However, significant differences were observed for FM in the pre-frail and FFM in the non-frail (FMBIA:18.4±5.6, FMDXA:16.9±5.0; FFMBIA:40.9±7.3, FFMDXA:40.0±6.7, P < 0.05, respectively). The DXA and BIA-derived body composition parameters correlated significantly with each other in the nonfrail and pre-frail (FM: r = 0.94, 0.97 and FFM: r = 0.98, 0.97, all P < 0.01, respectively). Bland-Altman plots demonstrated that there was a tendency towards an increasing overestimation of FM by BIA with increasing FM (r = -0.39, P = 0.05). In younger group, excellent correlation was observed between BIA and DXA (FM: r = 0.93, FFM = 0.98, P < 0.01, respectively). FMBIA tended to be overestimated with increasing FM (r = -0.27, P = 0.05) in Bland-Altman analysis. Conclusion: As compared to the DXA method, we found the BIA accurately assessed body composition in non-frail and pre-frail older adults, although FM had proportional bias. The accuracy of BIA did not differ between the younger and the elderly population. [ABSTRACT FROM AUTHOR]
