Figure 1. Effects of TNF-α on the contractile activity of pressurized rat mesenteric lymphatic vessels.

Figure 1

A. Original recordings of the contractile activity of lymphatic vessels pressurized at 5 cmH2O after a 24-h incubation without (sham) and with increasing concentrations (0.1, 1.0 and 10 ng/ml) of TNF-α. Time scale bar applies to all traces. B. TNF-α caused a concentration-dependent decrease in contraction frequency (top bar graph), but did not affect the amplitude of contractions or the tone index (n=4; *P<0.05, **P<0.01, repeated measures of ANOVA with Dunnett’s post-hoc test).
