Day and Night GSH and MDA Levels in Healthy Adults and Effects of Different Doses of Melatonin on These Parameters

<table>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 <i>in vitro</i> treatment. Significant change was observed at 10<sup>-9</sup> M concentration of melatonin (<svg height="13.95" id="M8" style="vertical-align:-0.1638pt" version="1.1" viewbox="0 0 58.162498 13.95" width="58.162498" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink">
