TNF and IL-10 levels in control and treatment groups.

Mean ± SEM plasma levels of TNF (upper panel) and IL-10 (lower panel) were measured upon lethal E coli infusion. The TNF response was significantly higher (P < .05) in the treatment group (•) compared with the control group (○). After 3 hours, levels of IL-10 were lower in the treatment group compared with the control group. *P < .05; and **P < .01.
