1.对五名健康的瘦成人进行了调查，以评估前臂和小腿体积图是否能很好地反映Xe-133测量的肌肉血流量，以及身体不同部位肌肉的血流量是否存在显著的变异性。使用Xe-133清除技术评估前臂和小腿屈伸肌、二头肌、三头肌和股四头肌的血流量。前臂皮肤和皮下脂肪组织的血流量也用Xe-133清除技术测量，而前臂和小腿的血流量用应变计体积描记法测量。不同肌肉的平均血流量分别为1.4+/-0.6(腓肠肌)和1.8+/-0.7(前臂伸肌)mlmin-1100g-1肌肉(1.4+/-0.6和1.9+/-0.8mlmin-1100ml-1肌肉)，但差异无统计学意义。前臂和小腿血流量(分别为2.7+/-0.3和3.0+/-0.7mlmin-1100ml-1肢体组织)增加约50%~100%以上(P
1. An investigation was carried out in five healthy lean adults to assess whether forearm and calf plethysmography largely reflect muscle blood flow as measured by Xe-133 and whether there is substantial variability in the blood flow to muscles located at different sites in the body.2. Blood flow to forearm and calf flexors and extensors, biceps, triceps and quadriceps was assessed using the Xe-133 clearance technique. Blood flow to forearm skin and subcutaneous adipose tissue was also measured using the Xe-133 clearance technique, whereas blood flow to the forearm and calf was measured using strain gauge plethysmography.3. The mean blood flow to different muscles ranged from 1.4+/-0.6 (gastrocnemius) to 1.8+/-0.7 (forearm extensor) ml min-1 100 g-1 muscle (1.4+/-0.6 and 1.9+/-0.8 ml min-1 100 ml-1 muscle, respectively) but there were no significant differences between them. Forearm and calf blood flows (2.7+/-0.3 and 3.0+/-0.7 ml min-1 100 ml-1 limb tissue, respectively) were about 50% to more than 100% greater (P
