Filtration coefficient and hydrostatic pressure have been measured in single capillaries and venules in the cat mesentery using a modification of the Landis (1927) single vessel occlusion technique. 2. Venules were found to be filtering fluid, not absorbing it as is often supposed. 3. The mean filtration coefficient in capillaries was 0.018 micrometers . s-1 . mmHg-1 (1.35 X 10(-10)m . s-1 . Pa-1) while that in venules, was 0.027 micrometers . s-1 . mmHg-1 (2.02 X 10(-10)m . s-1 . Pa-1). 4. In both capillaries and venules, filtration coefficient increased with decreasing pressure. 5. The difference between directly measured venular pressure and that calculated from the occlusion data was used to determine the contribution of the interstitium to fluid exchange. In the mesentery superfused with Krebs solution the tissue pressure so determined was found to be zero or subatmospheric initially but became increasingly positive with lengthening exposure of the mesentery.

采用对兰迪斯（1927年）单血管闭塞技术的改良方法，对猫肠系膜中的单个毛细血管和小静脉的滤过系数及流体静压进行了测量。2. 发现小静脉在滤过液体，并非如通常所认为的那样在吸收液体。3. 毛细血管中的平均滤过系数为0.018微米·秒⁻¹·毫米汞柱⁻¹（1.35×10⁻¹⁰米·秒⁻¹·帕⁻¹），而小静脉中的平均滤过系数为0.027微米·秒⁻¹·毫米汞柱⁻¹（2.02×10⁻¹⁰米·秒⁻¹·帕⁻¹）。4. 在毛细血管和小静脉中，滤过系数均随压力降低而增加。5. 用直接测量的小静脉压力与根据闭塞数据计算出的压力之间的差值来确定间质对液体交换的贡献。在用克雷布斯溶液灌注的肠系膜中，最初测定的组织压力为零或低于大气压，但随着肠系膜暴露时间延长，组织压力变得越来越正。
