[The immunomodulating action of bestatin in the combined therapy of bladder cancer patients].

A beneficial effect of bestatin used as adjuvant in the course of chemo- and radiotherapy of local cancer of the bladder manifested itself as a reduction of postradiation immunosuppression: increased count of T mu-helper/inductors and T gamma-suppressors/killers, enhancement of neutrophil phagocytic activity. Bestatin recovers radiation-impaired immune system by inhibition of T gamma-suppressor killers and their precursors generation, of endogenic regulators suppressive activity, normalization of T-lymphocyte and natural killer activity, stimulation of B-lymphocyte recovery.
