Preservation of resuspended red cell concentrate. Release of vesicles from stored red cells.
The effect of carbohydrates (sucrose, mannitol) and guanosine on red cell vesiculation was studied during storage of red cell concentrates (RCC) in glass bottles and plastic bags for 35 days. The course of vesicle release was followed by measuring acetylcholinesterase activity. It was found that sucrose and mannitol reduce the loss of membrane microvesicles. Preservation of red blood cells (RBC) in plastic bags results in a drastically retarded vesicle release.
