[Determination of serum fucosidase activities].

A method has been developed for simultaneous determination of the activity of alpha-L-fucosidase (EC 3.2.1.51) and the beta-D-fucosidase activity induced by beta-D-galactosidase (IV, EC 3.2.1.23) in the serum. The paper presents data on changes in these enzymatic activities in the serum in an experiment, in acute hematogenous osteomyelitis and recurrent laryngotracheitis in children in pregnant females with gestosis and placental insufficiency.
