2. Figure 1
Proliferation rate, measured as optical density (at 450 nm), of nonattached human peritoneal mesothelial cells incubated with either no (open bars), 0.05% (dotted bars), 0.1% (striped bars), 0.2% (hatched bars), or 0.4% sodium hyaluronate (solid bars), 4 or 24 hours after the addition of sodium hyaluronate (n = 8 each). Controls are considered as 100%. Results are presented as mean and SEM. ∗ = P<.05,∗∗ = P<.01, ∗∗∗ = P<.005, sodium hyaluronate vs. control.

4. Figure 3
Proliferation rate of attached human peritoneal mesothelial cells treated with either LPS, TNFα, or a combination of both, and incubated with either no (open bars) or 0.2% (hatched bars) sodium hyaluronate, 4 and 24 hours after incubation (n = 8 each). Controls are considered as 100%. Results are presented as mean and SEM. ∗ = P<.05, ∗∗ = P<.001, sodium hyaluronate vs. control. + = P<.005, cells treated with proinflammatory mediators vs. untreated cells. Con = control.

5. Figure 4
Proliferation rate of attached human peritoneal mesothelial cells preincubated for 24 hours with either LPS, TNFα, or a combination of both, and treated with no (open bars) or 0.2% (hatched bars) sodium hyaluronate for 4 hours (n = 8 each). Controls are considered as 100%. Results are presented as mean and SEM. ∗ = P<.001, sodium hyaluronate vs. control. + = P<.05; ++ = P<.01, cells treated with proinflammatory mediators vs. untreated cells. Con = control.
