Figure 3. Production of interleukins (IL)-1 [small beta, Greek], -2, and -6, and tumor necrosis factor-[small alpha, Greek](TNF-[small alpha, Greek]) by peripheral blood mononuclear cells of the hypothermia and normothermia groups. *IL-1 [small beta, Greek] and IL-2 production were significantly suppressed in the hypothermia group compared with the normothermia group at 24 h.aIL-6 and TNF-[small alpha, Greek] levels were significantly elevated at 48 h compared with baseline values. Values are mean (+/− SD). For details, see the legend to Figure 2.
