Effects of dexamethasone (1 mg/kg, i.p.) administered either 1 hr before (pre‐DEX) or 1 hr after (post‐DEX) lipopolysaccharide (LPS) (4 mg/kg, i.p.) injection on (A) plasma H₂S concentration and (B) H₂S synthesis from added L‐cysteine in liver homogenates in samples obtained 4 hrs after LPS injection. ‘Saline’ indicates data from animals injected with saline (1 ml/kg, i.p.) in place of LPS. ‘Veh + LPS’ indicates data obtained from animals injected with vehicle for dexamethasone (ethanol/olive oil 5/95 v/v, 1 ml/kg) 1 hr before LPS (4 mg/kg, i.p.) administration. ‘Mif+DEX+LPS’ indicates data from animals pre‐treated with mifepristone. Results are mean ± S.E., n= 6.
