[Dynamics of the cellular and humoral immunity indices before and after closed commissurotomy]. 
The state of the cellular and humoral immunity was studied in patients with acquired valvular disease of rheumatic etiology who were subjected to closed commissurotomy.  It was established that the patients whose postoperative course was complicated by a suppuration of the wound had low levels of T-lymphocytes, immunoglobulins in their peripheral blood in the postoperative period.  A dramatic elevation of the content of immunoglobulins of all classes on the 7th day of the postoperative period is considered to be the evidence of the development of an infectious process.
