摘要

本研究之目的，乃利用Xe-133清除法(Xe-133 clearance method)來測量正常中國人下肢肌肉血流，以建立中國人下肢肌肉血流之正常值，並評估不同緎別、年齡群間之差異。本文共收集99位健康者，依年齡分成三群：GroupⅠ：40歲以下，共34位，GroupⅡ：41-60歲，共30位，GroupⅢ：61歲以上，共35位。另再依性別分成二群，男性51人，女性48人。所有受檢者均於右腿脛前肌處注射Xe-133溶液，測量其肌肉血流。結果GroupⅠ下肢肌血流為3.21±1.29 (ml/100gm/min)（以下省略），GroupⅡ為3.19±1.28，GroupⅢ為2.71±1.71，男性為3.09±1.38，女性為2.96±1.24。用nupaired Student’s t test統計分析發現GroupⅠ與GroupⅡ及男性與女性間沒有統計學上的差異，而GroupⅠ與GroupⅡ及GroupⅡ與GroupⅢ間，則呈些微的差別(p值分別為0.09與0.11)。
我們的結論認為正常中國人下肢肌肉血流的影響，60歲以前影響甚微，直至61歲以後才較為顯著。

The Xe-133 clearance method is used to measure muscle blood flow in the lower limbs to establish normal values and evaluate the variance between different sex and age groups in healthy Chinese.
99 healthy volunteers were included in this study and divided into three groups according to age and two groups according to sex. Group I: ＜40 y/o, 34 persons; Group II: 41-60 y/o, 30 persons; Group III:＞60 y/o, 35 pesons; male group: 51 persons; and female group: 48 persons. Intramuscular injection of Xe-133 saline solution in the anterior tibial muscle of the right leg was performed in all the volunteers to calculate muscle blood flow. The muscle blood flow is 3.21±1.29 ml/100gm/min in Group I, 3.19±1.28 ml/100gm/min in Group II, 2.71±1.71 ml/100gm/min in Group III, 3.09±1.38 in male, and 2.96±1.24 in female. There was no significant difference in Groups I and II, or in the male and female groups using the Student’s test for unpaired data. However, a mild difference was observed between Groups I and III, and between Groups II and III (P values of 0.09 and 0.11 respectively).
We conclude that there is no variance of muscle blood flow in the lower limbs between different sexes and the effect of aging on peripheral muscle blood flow is not significant before 60 in healthy Chinese.
