[Correction of immunity and hemostasis with peptides from the bursa of Fabricius and bone marrow in embryonically bursectomized chicks].

Peptides from the bursa of Fabricius were shown to normalize immunogenesis, blood coagulation and fibrinolysis in bursectomized chicks to a greater extent than those from the bone marrow. Antigen-independent differentiation of B-lymphocytes can probably take place under the influence of peptides from the bursa of Fabricius in bursectomized chicks.
