Abstract
The treatment of human polymorphonuclear cells by neuraminidase "type-X" removes about 15% of cell sialic acid without modifications of NADPH oxidase activity of granulocytes before and after stimulation by opsonized zymosan. A mild periodate treatment oxidizes only the poly-hydroxilic chain of sialic acid with formation of aldehyde groups. This treatment increases cellular NADPH oxidase activity and also largely prevents the stimulation of polymorphonuclear cells by opsonized zymosan.
