Adherence of neutrophils from dogs with diabetes mellitus.

Adherence of neutrophils from dogs with type I (insulin-dependent) diabetes mellitus controlled by insulin administration was compared with that from control dogs. Neutrophil adherence in whole blood decreased with increased serum glucose concentration, but was not different from normal cell adherence when isolated cells were examined. The decreased adherence in whole blood was considered to be the result of media factors and not dependent on altered neutrophil function.
