Abstract
Diamide, CDNB and phorone were used to deplete glutathione in retrogradely perfused rat hearts. Following glutathione depletion the spontaneous chemiluminescence increased by 70%, irrespective of the agent used. The glutathione depletion and the chemiluminescence emission were associated to an increase of malondialdehyde content in the heart, as determined by HPLC. Under these conditions the heart function was impaired and histological examination showed a coagulative myocytolysis, a pattern already described in human and experimental pathology, where a key role is attributed to a Ca2+ homeostasis impairment.File in questo prodotto:
