Changes in in vivo endotoxin clearance and cytokine levels. (a) Endotoxin levels in portal vein blood. Levels were determined immediately following the end of the final exercise load. (b) Time course of endotoxin levels in peripheral blood. (c) Time course of cytokine levels in peripheral blood. (b,c) After administration of endotoxin (0.01 µg/g body weight) into the tail vein, blood was sampled prior to administration (Pre), and at time points of 1.5 h, 3.0 h, 6.0 h, and 12 h following administration. For all groups, n = 8. Values are expressed as mean ± standard error. *P < 0.05, significantly different from the 3moR group.
