Day and Night GSH and MDA Levels in Healthy Adults and Effects of Different Doses of Melatonin on These Parameters
Day and night variation in reduced glutathione (GSH) content in red blood cells after in vitro treatment with melatonin. The points (□) and (■) represent the effect of melatonin in diurnal and nocturnal blood samples respectively. Dose-dependent variation was observed in both diurnal and nocturnal samples in response to in vitro treatment. Significant change was observed at 10-9 M concentration of melatonin (). GSH content is expressed as milligram per millilitre packed RBCs.
