Quantitative Analysis of Cystic Fluid Components in Cysticercus cellulosae

Free amino acid(FAA), free fatty acid(FFA), and amino acid obtained by hydrolysis of protein components of cystic fluid(CF) of Cysticercus cellulosae in pig and man were analyzed. FFA was analyzed by gas chromatography using Varian model 2700, and flame ionization detector with 6 feet${\times}$1/4inch glass column. Flow rate of $N_2$ was 30 ml/min, $H_2$ was 30 ml/min, air was 350 ml/min respectively and chart speed was 1 cm/min. Amino acid was analyzed by high performance liquid chromatography using Waters model 441, and fluorescence detector at 338nm/425nm with column of amino acid analyzer. Buffer A of mobile phase was pH 3.05 and pH of buffer B was 9.6 respectively. The results obtained were as follows : Seven FFAs containing 12~18 carbons were detected : Saturated fatty acids were lauric acid ($C_{12}$), myristic acid($C_{14}$), palmitic acid($C_{16}$), Stearic acid($C_{18}$). Unsaturated fatty acids were oleic acid($C_{12}^{=1}$), linoleic acid($C_{12}^{=2}$), and one unidentified fatty acid was detected. Generally much more quantity of FFA was determined in CF obtained from pig than that from man. FFA of the largest quantity was palmitic acid; 0.078 mg/ml. Eighteen FAAs were detected and the largest quantity was alanine. Ouantity of alanine was 386 ug/ml in CF from pig 108 ug/ml in CF from man respectively. while histidine in CF from pig was 273 ug/ml, that from man was only 4.3 ug/ml. Eighteen amino acids were identified by hydrolysis of protein in CF from man. But, histidine was not identified in CF from pig. Amino from pig and ug/ml from man.
