Abstract
Glutathione (GSH) levels were measured in platelet-rich plasma (PRP) and concentrates
at 4 hour intervals during storage. The values fell steadily during the first several
hours after collection at 9:00 a.m., reaching the lowest level at midnight, 14 hours
later. Subsequently, the levels rose to a new peak value at 4:00 a.m. GSH levels continued
to show cyclic variation over the 48 hours examined in this study. Change in schedules
of light and dark under which the platelets were stored had no effect on GSH periodicity.
Platelets from night shift workers also displayed a similar periodicity to that of
day workers. Erythrocytes failed to demonstrate a similar time related variation in
GSH levels during storage.
