A method for measurement of capillary permeability using external registration of gamma emitting isotopes after close arterial bolus injection was applied to the isolated inguinal fat pad in slightly fasting rabbits. An average extraction of 26 per cent for 51Cr-EDTA was found at a plasma flow of about 7 ml/100 g-min. This corresponds to a capillary diffusion capacity of 2.0 ml/100 g-min which is half the value reported for vasodilated skeletal muscle having approximately twice as great capillary surface area. Thus, adipose tissue has about the same capillary permeability during slight metabolic activation as vasodilated skeletal muscle.
一种在动脉快速推注后通过γ发射同位素的外部记录来测量毛细血管通透性的方法，被应用于轻度禁食兔子的离体腹股沟脂肪垫。在血浆流量约为7 ml/100 g-分钟时，发现51Cr-EDTA的平均提取率为26%。这相当于毛细血管扩散能力为2.0 ml/100 g-分钟，该值是报道的血管舒张骨骼肌的一半，而血管舒张骨骼肌的毛细血管表面积约为其两倍。因此，在轻微代谢激活期间，脂肪组织的毛细血管通透性与血管舒张骨骼肌大致相同。
