We evaluated the optimal condition for the assay of volatile hydrocarbons produced by oxidation of red blood cells in vitro by hydrogen peroxide. As a result, we chose the condition of 4.3% packed cell volume (PCV), 37.8mM hydrogen peroxide and for inhibition of catalase activity, 42.8mM sodium azide in final concentration.<BR>Sources of the volatile hydrocarbons were suggested to be red blood cell membranes for n-pentane, but unclear for other volatile hydrocarbons such as n-propane and n-butane.<BR>During aging of red blood cells, production of ethane and n-pentane, which were volatile hydrocarbons specifically produced from red blood cell membranes, did not change signifi-cantly, while that of other uncharacterized hydrocarbons increased. Therefore, it was suggested that there was no change with cell aging in the hydrocarbon production from red blood cell membranes.
