Concentrations of interleukin-6 (IL-6) ( A ) and leukocytes in bronchoalveolar lavage (BAL) fluid ( B ) obtained from mice after high tidal volume (HV T ) ventilation. IL-6 and leukocyte concentrations were measured subsequent to HV T ventilation in the presence and absence of inhaled hydrogen sulfide (H 2 S) (n = 6 for each concentration) or after intravascular administration of sodium sulfide (Na 2 S) or vehicle (n = 8 in each group), and in control mice not subjected to HV T ventilation (n = 4). n/d = not detectable.
