we determined by affinity chromatography on concanavalin a-sepharose the carbohydrate variant patterns of alphafetoprotein in the sera of 15 infants and children with endodermal sinus tumors ( five cases ) , a neonatal mature teratoma ( one case ) , hepatoblastomas ( two cases ) , pancreatic carcinoma ( one case ) , biliary atresia ( four cases ) , neonatal hepatitis ( one case ) and neonatal hyperbilirubinemia ( one case ) , in the sera from four normal neonates , and in the sera from two kinds of nude mice bearing human endodermal sinus tumors .
