Abstract
Despite advances in the measurement of lymphatic flow, little is known about the actual velocities of flow in microlymphatic (~100 um diameter) vessels. In this paper, video microscopy and particle tracking methods were adapted and integrated with an ultra high-speed imaging camera to obtain measurements of high-speed lymph velocities that previous systems were incapable of measuring. In this study, a mesenteric microlymphatic vessel in a loop of the small intestine of a male Sprague-Dawley rat was exteriorized and imaged at a rate of 500 frames per second (fps) for several contraction sequences. Lymph velocity was shown to fluctuate cyclically with the vessel wall contractions and ranged from -1 to 4 mm/sec through a ten second sequence.
