Protection by sodium hydrosulphide (NaHS) of pancreatic islets from oxidative stress induced by hydrogen peroxide (H₂O₂). Mouse pancreatic islets were cultured for the indicated durations with 5 mmol·L⁻¹ glucose alone or 5 mmol·L⁻¹ glucose plus 10 µmol·L⁻¹ H₂O₂ in the presence or absence of 0.1 mmol·L⁻¹ NaHS. After this, histone-associated DNA fragments were quantified by elisa to evaluate apoptotic cell death. Each column represents the mean ± SE from three to five separate experiments. *P < 0.05.
