Aging-associated alterations in lymph flow velocity (A) and wall shear stress (B) in the 9- and 24-mo rat mesenteric vessels in vivo under control conditions and after nonspecific NOS blockade induced by 100 μM of l-NAME for 5 and 15 min. DV, diastolic lymph flow velocity; SV, systolic lymph flow velocity; D Sh S, diastolic wall shear stress; S Sh S, systolic wall shear stress; l-NAME 5 min and l-NAME 15 min, same parameters during the l-NAME (100 μM) administration within first 5 min and between 5 and 15 min, respectively. Significant differences between active lymph pump parameters: #P ≤ 0.05, 9-mo control vs. 24-mo control; *P ≤ 0.05, 9-mo control vs. 9-mo l-NAME conditions and 24-mo control vs. 24-mo l-NAME conditions.
