a concurrent stimulation of secretion of unique low molecular weight sulphate-rich components and high molecular weight mucin complexes with increased ca2+ influx into and efflux from the tracheal tissue in response to high serosal and low luminal [ ca2+ ] allude to a plausible role of these secretory macromolecular mucin complexes as cellular ca2+ transport vehicles .
