	note = {@ THE MUCOCILIARY URN CELL COMPLEX OF S. NUDUS SECRETES MUCUS 4-5 MINUTES AFTER BEING EXPOSED TO LOTUS TETRAGONOLOBUS AND RICINUS COMMUNIS AGGLUTININS. SURFACE BINDING OF BOTH LECTINS IS CONFINED TO THE SECRETORY AREA OF THE URN CELL COMPLEX AND, LIKE THE RELEASE OF MUCUS, IS INHIBITED BY THE SPECIFIC SACCHARIDES L-FUCOSE AND D-GALACTOSE OR BY INCUBATION IN L-FUCOSIDASE \& D-GALACTOSIDASE. MUCUS SECRETION MAY THEREFORE BY INITIATED BY THE INTERACTION OF MUCUS-RELEASING STIMULI WITH FUCOSYL OR GALACTOSYL RESIDUES OF SPECIFIC MAMBRANE RECEPTORS. *FROM TEXT* URN CELL COMPLEX CONSIST OF ANTERIOR VESICLE CELL AND POSTERIOR BASAL CELL. MUCUS SECRETED FROM BASAL CELL IN RESPONSE TO A VARIETY OF STIMULI, E.G. FOREIGH CELLS, EPITHELIAL SECRETIONS, AND HEATED AUTOLOGOUS AND HETEROLOGOUS SERUMS. IMPORTANT ROLE IN IMMUNE RESPONSE.. TRAP THEN PHAGOCYT, LYSED BY OTHER COEL CELLS.},
