The superficial microlymphatics were visualized by intravital fluorescencemicrolymphography, cannulated with glass micropipettes, and the lymph capillary pressure was measured using a servo-nulling pressure system.</p><p>In group A, lymph capillary pressure measured in the morning (mean 7.5 ± 4.4 mmHg; range -4 to 16 mmHg) did not differ (p>0.05) from the pressure in the late afternoon (mean value 5.6 ± 3.4 mmHg; range -1 to 13 mmHg). In group B, initial lymph capillary pressure (mean 3.9 ± 2.9 mmHg, range -1.1 to 9.7mmHg) was not different (p>0.05) compared with the pressure after 7 weeks (2.9 ± 2.7 mmHg, range -1.0 to 6.8 mmHg).</p><p>We conclude that lymph capillary pressure in healthy subjects does not exhibit significant changes during the daytime or over the long term.</p>}, month = {8}, pages = {122-127}, issn = {2522-7963}, publisher={International Society of Lymphology and the University of Arizona Libraries}, journal = {Lymphology} }
