Abstract/OtherAbstract:
Synthesis of NAD+ from nicotinic acid by erythrocytes incubated in SAGM phosphate solution and effect of di-[2-ethyl hexyl] phthalate, a plasticizer commonly used in PVC blood/component storage bags, on this synthesis was studied. Erythrocytes are able to synthesise NAD+ in SAGM (sodium chloride, adenine, glucose, mannitol) phosphate solution and this synthesis was more in the presence of added nicotinic acid (optimum concentration 1 mM). The level of NAD+ decreased when the incubation period was increased from 24 to 48 hr. Glutamine had a deleterious effect on this synthesis, possibly due to the decrease in pH. Di-[2-ethyl hexyl] phthalate had an inhibitory effect on NAD+ synthesis when the cells were incubated in SAGM phosphate solution, either alone or in the presence of added nicotinic acid. There was significant decrease in the release of potassium and haemoglobin from the cells in the presence of nicotinic acid, indicating increased red cell stability.
