[Effects of leuzea tincture and leveton on humoral immunity of athletes].

The effect of 20-day administration of ectisten-containing tincture of leuzea and leveton on humoral immunity of track and field runners for distances of 5,000 and 10,000 m was studied. Intensive cyclic physical activity induced significant decrease of IgG and IgA in blood serum of the athletes as well as the complement C3 component on the 10th and 20th days. Both drugs contributed to restoration of the lowered IgG, IgA, and C3 concentration. The effect of leveton was more pronounced. The working capacity of the athletes grew by 10 to 15% in this case.
