ABSTRACT
The short chain fatty acids inplatelet concentrate (PC) and serumwere determined by means of gaschromatography.The short chainfatty acids determined includeacetic,propionic,butyric,isobuty-ric,valeric,isovaleric,lactic,pyruvic and succinic acids.Therewere acetic,lactic,pyruvic andsuceinic acids in PC;their relativecontents were 1.14,13.50,1.41 and9.54,respectively.The serum cont-ained acetic,lactic and pyruvic aci-ds;their relative contents were0.98,4.33 and 1.88,respectively.Succinic acid wasn't found in theserum,suggesting that the succinicacid in PC is the content of platelets.There was a positive correlationbetween the platelet count and lacticacid content of PC.Fresh PC wascompared with the PC of same volumepreserved for 0,24,48,72 hours atroom temperature.The lactic acidcontent of PC increased with thetime of preservation.
