要旨
【はじめに】移乗する際の立ち上がり動作の容易性は,筋活動に対する負担の軽減につながる.本研究は,座面高と座面角の組み合わせが移乗する際の立ち上がり動作(Sit to stand)にどのような影響を及ぼすか,筋活動を評価指標として検証することを目的とした.【方法】12人の健常成人男性を対象に立ち上がり動作時の下肢筋活動を表面筋電図計で測定した.座面高3パターン,座面角も3パターンとし,組み合わせた計9パターンの椅子を準備.%MVCを従属変数,座面高と座面角を実験変数とし,二元配置分散分析を行った.【結果】4つの筋群すべてにおいて,座面高の主効果を認め,座面高を5cm高くすることで%MVCが有意に小さくなった.大腿直筋において,座面角の主効果を認め,前傾は後傾より%MVCが小さかった.【考察】高座面の椅子は筋活動の軽減につながる.また,座面角において,座面を前傾させることで,離殿時までの重心の前方移動に影響をあたえる大腿直筋への負荷を軽減させることが明らかになった.キーワード

Abstract
Background:The ease of sit-to-stand(STS)leads to reduction of burden on muscle activity. In the previous study, it is reported that the the height and tilting angle of a seating face(HAS)can influence the STS. It is, however, unclear how the HAS affects the STS. The aim of the present study is to examine the combination of HAS to ease the STS. Methods:Subjects were 12 healthy men. Evaluation of muscle activity was performed on the surface electromyography(SE). SE adhered to Vastus lateralis(VL), Rectus femoris(RF), Vastus medialis and Tibialis anterior. Each HAS prepared 3 patterns. Therefore, the STS experiment was conducted with 9 patterns in total(3×3 patterns combined). HAS was analyzed in a two-way analysis of variance(two-way ANOVA). Results:In VL, there was a significant difference due to HAS difference(p=0.027). There was a significant difference in the height of each muscle group(p=0.000), Angle was only RF significant(p=0.009). Conclusion:Combination of HAS was effective in VL. it was found that high chair has small muscle activity and low chair has large muscle activity. RF muscle activity is alleviated by anteversion angle.Keyword

要旨
本研究は妊娠後期の乳腺組織の厚みの変化を明らかにし,分娩前の乳腺組織の厚みと産後3~5日目の乳汁分泌量との関係を明らかにすることを目的とした.対象は妊娠34~35週の妊婦で,携帯型超音波診断装置(Vscan Dual Probe)を用いて妊娠34~35週より分娩前1~7日まで妊婦健康診査の時期において乳腺組織の厚みを継続的に測定した.分析対象は産褥婦14名であった.分娩直前の乳腺組織の厚み29.0mmを基準として2群に分類し,群分けしたグループと産後日数および両者の交互作用を固定効果,対象者を変量効果とした線形混合モデルで分析した結果,乳汁分泌量に関連していた固定効果は乳腺組織の厚みと産後日数であり,有意な固定効果がみられた(p=.030,.001).すなわち29.0mm以上の群ではそうではない群にくらべ乳汁分泌量が有意に多かった.以上のことより,分娩前における最終妊婦健康診査時の乳腺組織の厚みと産後乳汁分泌量との関連が示唆された.キーワード

Abstract
We examined the relationship between the thickness of the mammary glands in late pregnancy and the amount of breast milk produced 3-5 days after giving birth. Fourteen pregnant women in this study were at 34-35 weeks of gestation. We measured the thickness of their mammary glands during each checkup from the 34th or 35th week of their pregnancy to the final checkup before delivery, using portable ultrasonic diagnostic equipment(Vscan Dual Probe). We divided the subjects into two groups on the basis of the thickness of the mammary glands before delivery using 29.0mm. We used the linear mixed model to analyze this study, by grouping the subjects and postpartum days, defining the interaction as fixed effect, and the subjects as random effect. We showed that the amount of breast milk produced by women was significantly related with groups and postpartum days(p=.030, .001). The amount of breast milk produced by women with a mammary gland thickness of 29.0mm or more was significantly greater than that of women with a mammary gland thickness of less than 29.0mm. These findings suggest a relationship between the thickness of the mammary glands at the final checkup before delivery and the amount of breast milk produced after giving birth.Keyword

要旨
本研究の目的は,携帯型超音波検査装置(HHU)を用いて,特に少ない排尿量に対する2つの膀胱内尿量推定法の妥当性を評価することである.排尿前に5機種のHHUによるスキャンを行い,その直後に排尿量を計測した.Diameter法またはArea法のいずれかを使用し,膀胱内尿量推定値を算出した.Diameter法を用いたHHU-A,HHU-B,およびHHU-Cの3機種では,膀胱の3点の直径を手動で計測し,計算式により膀胱内尿量推定値を算出した.Area法を用いたHHU-DおよびHHU-Eの2機種では,膀胱の自動測定により膀胱内尿量推定値が算出された.排尿量が150ml未満のデータを分析対象として,排尿量を真値とし,回帰係数を算出した.回帰係数は,Diameter法の3機種でそれぞれHHU-A(β=0.95),HHU-B(β=0.87),HHU-D(β=1.17),Area法の2機種でそれぞれHHU-C(β=1.20),HHU-E(β=0.67)であった.手動によるDiameter法を用いたHHUによる膀胱内尿量推定法はArea法よりも高い妥当性を示し,正確な膀胱内尿量を推定できる可能性が明らかになった.キーワード

Abstract
The aim of this study was to evaluate the validity of two methods of bladder volume estimation with respect to the voided volume and a small voided volume using hand-held ultrasound(HHU)devices. HHU devices were used in a random sequence prior to urination, followed by the estimation of voided volume. Estimated volume was then calculated using either diameter method or area method. Three devices(HHU-A, HHU-B, and HHU-C)used manual measurements of three bladder diameters(diameter method). Two devices(HHU-D and HHU-E)used automatic measurements of bladder area(area method). Regression coefficient was calculated using voided volume as the true value. In total, 36 data-points were obtained and the regression coefficient was closest to one in the order of HHU-A(β=0.95), HHU-B(β=0.87), HHU-D(β=1.17), HHU-C(β=1.20), and HHU-E(β=0.67). In total, 23 data-points of less than 150 ml were obtained and the regression coefficient was closest to one in HHU-A(β=0.95), HHU-B(β=0.87), HHU-D(β=1.17), HHU-C(β=1.20), and HHU-E(β=0.67). HHU devices using the manual diameter method had higher validity than those using the area method.Keyword

要旨
本研究では,新生児皮膚におけるスキンブロッティングによる炎症性サイトカイン検出が,皮膚トラブルの客観的評価指標となりうるのかを検討した.新生児の無疹部と皮疹部において,TEWL値やスキンブロッティングによるアルブミンあるいは炎症性サイトカイン(IL-1α,IL-6,TNF-α)検出強度を比較した結果,炎症性サイトカインのIL-6とTNF-αが,無疹部よりも皮疹部のほうで有意(p<0.05)に高く検出された.また皮膚トラブルを検出するためのカットオフ値は,IL-6が2.77μg,TNF-αは8.15μgとなった.このカットオフ値ではどちらの場合も感度と特異度は0.86と1.00であり,AUC(Area Under the Curve)は0.92あった.以上より,スキンブロッティングによるIL-6とTNF-αの検出は,新生児における皮膚トラブルの客観的評価指標となりうることが示唆された.キーワード

Abstract
In this study, we examined whether the detection of inflammatory cytokines in the skin of newborns by skin blotting can serve as an objective measure of skin problems. We compared the detection strengths of albumin and inflammatory cytokines(interleukin(IL)-1α, IL-6 and tumor necrosis factor(TNF)-α)obtained using transepidermal water loss values or skin blotting of rash-presenting and non-rash-presenting neonatal skin, and found that the detection strengths of IL-6 and TNF-α inflammatory cytokines were significantly higher(p<0.05)in skin with rashes than in that without. Furthermore, the cut-off values for the detection of skin problems were 2.77μg and 8.15μg for IL-6 and TNF-α, respectively. Both of these cut-off values had a sensitivity of 0.86, a specificity of 1.00, and an area under the curve of 0.92. These findings suggest that the detection of IL-6 and TNF-α by skin blotting may serve as an objective measure of skin problems in newborns.Keyword
