[Role of initial immunologic status of patients with congenital heart defects in the development of postoperative infectious complications]. / Rol' iskhodnogo immunologicheskogo statusa organizma bol'nykh vrozhdennymi porokami serdtsa v razvitii posleoperatsionnykh infektsionnykh oslozhnenii.

Before surgical correction of the defect, the immune status was examined in 65 patients with congenital heart disease who developed postoperative infectious complications. The patients showed significant changes in peripheral blood levels of various lymphocyte populations (E-, EAC-ROC) and immunoglobulins M, G, A. It was concluded that the occurrence of infections complications was related to the initial immunological status of patients with congenital heart disease.

[T and B lymphocyte function of patients with infectious complications after surgery for congenital heart defects]. / Sostoianie T- i B-limfotsitov u bol'nykh s infektsionnymi oslozhneniiami posle operatsii po povodu vrozhdennykh porokov serdtsa.

The parameters of T- and B-lymphocyte system were studied in 65 patients with congenital heart defects aged from 2 to 31 years with infectious complications after operation. The investigation was performed before operation and in the course of the postoperative period. Patients with infectious complications were shown to have more considerable suppression of cell and humoral immunity before operation than those without infectious complications. The parameters concerned were found to be distinctly decreased in the early postoperative period. Two weeks after operation no normalization of the immune parameters were noted.

[Most efficient methods of cryodestruction of malignant neoplasms]. / O naibolee ratsional'nykh metodikakh kriodestruktsii zlokachestvennykh novoobrazovanii.

Some peculiarities of the procedure for cryodestruction of neoplasms of various sites developed by the authors are considered. The regularities of variation in the adhesion of cryoapplicator to tissues on gradual cooling are discussed. The report is concerned with cryogenic procedures designed to ensure destruction of tumor cells and to prevent tumor cell dissemination in the course of surgical intervention. The cryogenic installation Penguin was used. Such effects as applicator's adhesion to tissue and its freezing-induced fixation in tissue were employed. Thawing period was prolonged with cryoapplicator still in contact with tissue. Tumor tissue adjacent to normal one was allowed to thaw to 0 degrees C.
