Concanavalin (ConA), Phytohemagglutinin (PHA), Pokeweed agglutinin (PWM) and Lipopolysaccharide (LPS) binding sites were distributed mainly on the plasma membrane of lymphocytes. ConA, PHA binding sites were distributed in thymus, cordic structure of head kidney and scatterly spleenic tissue of C. idellus, also in thymus and periellipsoidal lymphatic sheaths and marginal region of T. sinensis. PWM, LPS binding sites were scatterly distributed in cordic structure of head kidney of C. idellus, spleenic tissue of C. idellus and T. sinensis, but positive cell groups were not obvious. ConA, PHA and PWM positive percents of lymphocytes in blood smears were repectively 36%～41%, 33%～37%, 38%～43% in C. idellus and 37%～48%, 36%～45%, 44%～53% in T. sinensis, but percents of positive cells were repectively 15%～18%, 14%～17%, 9%～12% in imprints of head kidney of C. idellus.展开更多
