Myocardial levels of IL-6 (A) and TNF-α (B) proteins and MCP-1 (C) and VCAM (D) mRNA in control and exercised rats exposed to intermittent hypoxia or room air for 14 days.

<p>Values are mean±SEM; n = 5 per group. ^†<i>p</i><0.05 compared with CON-Veh; ^‡<i>p</i><0.05 compared with IHCON-Veh; ^§<i>p</i><0.05, compared with vehicle injections in all four groups (CON, IHCON, EXE, and IHEXE); ^¶<i>p</i><0.05 compared with zinc injections in all four groups. CON, controls; IHCON, intermittent hypoxia; EXE, exercise; IHEXE, IH interspersed with EXE; Veh, vehicle injection; zinc, zinc chloride injection; TPEN, N,N,N',N'-tetrakis(2-pyridylmethyl) ethylenediamine injection.
