Abstract | 「要旨」正常人と糖尿病例の下肢血流量を133Xeクリアランス法とアドミタンスプレチスモグラフィで測定した. 133Xeクリアランス法では, 筋(Fm)と皮膚(Fs)の血流量を分離測定した. 下肢組織のVolume%を筋70%, 皮膚10%とした場合, アドミタンス法によって測定した全血流量(Fy)と筋・皮膚における有効栄養血流量(Fn=0.7Fm+0.lFs)との間にはFy=1.22Fn-0.15(ml/min/100g)の関係があった. 骨血流量を含んだ短絡血流量は, 正常下肢全血流量の11%を占めていたが, 糖尿病例では全下肢血流量の減少に加えて, 短絡血流量の増加(31%)がみられた. 133Xeクリアランス法とアドミタンス法によって, 病的状態における短絡血流量の評価が可能となった. 「I. はじめに」全下肢血流量に対する皮膚血流量と筋血流量の関与について検討し, 糖尿病性毛細血管症における短絡血流量について推定した. |

Abstract | [Summary]The Xe-133-clearance method and the admittance plethysmography were simultaneously performed to measure the limb circulation in the normal subjects and in the diabetic patients. From the Xe-133-clearance curve, blood flow rates in the muscle (Fm) and in the skin (Fs) were separately measured. When the volume percent of the calf tissues was expressed as 70 % for the muscle and 10 % for the skin, the relationship between the total blood flow (Fy) measured by the admittance plethysmography and the nutrient flow (Fn) in the muscle and skin (Fn=0.70 Fm+0.1 Fs) was Fy=1.22 Fn-0.15 (ml/min/100 g tissue). The sum of the blood flow in the bone and the non-nutrient shunt flow was about 11 % of total blood flow in the calf. In the diabetic patients, the non-nutrient shunt flow increased associated with a reduction of the total flow in the calf. A combined study of the admittance plethysmography and the Xe-133-clearance method is useful to estimate the non-nutrient flow in the pathologic condition of lower extremities. |
