[Polymorphonuclear neutrophil adhesion in patients with diabetes mellitus]

The adherence of polymorphonuclear neutrophils was evaluated in patients with type I and type II diabetes as well as in group of elderly people. The adherence of these cells suspended in plasma: autologous, control, inactivated, zymosan-activated and in FMLP solution was estimated. The adherence of polymorphonuclear neutrophils obtained from controls after the suspension of cells in diabetic plasma was also estimated. The estimations were also performed after the heat-inactivation of diabetic plasma and its activation by zymosan. The obtained results seem to indicate that the enhanced adherence of polymorphonuclear neutrophils in diabetic patients is due to the presence of heterogeneous plasma factors.
