[The immune status of patients who have undergone reconstructive operations on the jaws using different types of transplants]. / Immunnyi status bol'nykh, perenesshikh rekonstruktivnye operatsii na cheliusti s ispol'zovaniem raznykh tipov transplantatov.

Lymphocyte subpopulations were studied in 18 patients by flow cytometry using monoclonal antibodies before and after surgical repair of the mandible with different transplants. All the transplants used had a stimulating effect on the immunity system. The most marked changes in the time course of immunologic parameters were observed after transplantation of frozen bone and formalin-treated grafts.

[The use of tactivin in the combined treatment and prevention of complications in reconstructive operations on the bones of the facial skeleton]. / Primenenie taktivina v kompleksnom lechenii i profilaktike oslozhnenii pri rekonstruktivnykh operatsiiakh na kostiakh litsevogo skeleta.

Sixty-three patients with congenital and acquired defects and deformations of facial bones without concomitant diseases were examined. Twenty-eight of them were operated on; auto- and alloplasty was resorted to in 18 patients, and to 10 patients tactivin was administered after common protocols for immunocorrection before or after surgery. Immunologic and clinical studies showed that immunodeficiency states are the most probable causes of postoperative complications following repair surgery on the facial bones. Tactivin normalized the immunity parameters and prevented the development of postoperative complications.
