Spontaneous and DTT-induced recovery of respiratory function in J774 cells after long-term exposure to NO. (A) Cells were treated with DETA-NO (0.5 mM) for 6 h in the incubation medium under sterile conditions, then washed, resuspended in culture medium, and maintained in the cell incubator. Oxygen consumption by cell samples was determined at the indicated time points (n = 3). (B) Cells were treated with DETA-NO (0.5 mM) for 6 h in the incubation medium. Increasing concentrations of DTT were added 5 min before addition of Hb (8 μM), after which oxygen consumption was measured (n = 6).
