Immune Status of Pancreatic Cancer Patients Receiving Cryosurgery.

Cryosurgery used on patients with unresectable pancreatic cancer improved their quality of life, but mainly because of the pain relief. In postoperative patients, multifaceted changes in immunity were found, and the state of the immune system prior to surgery often was a decisive factor to indicate whether further disorders in the postoperative period would develop, or by contrast, it would boost its recovery. Some patients receiving cryosurgery showed immune system imbalance and activation, and of antitumor immunity in particular.

[Risk factors and prevention of postoperative pancreatitis after pancreatectomy].

Aim: to improve the results of pancreatic resections through decrease of postoperative pancreatitis incidence.

Material And Methods: It was analyzed 207 patients who underwent pancreatic surgery for pancreatic tumor (n=137) or chronic pancreatitis (n=70). 22 risk factors of postoperative pancreatitis were analyzed in 112 patients retrospectively.

[Clinical efficacy of immunostimulating drugs in treatment of purulent infections].

81 patients with the acute soft tissue purulent infections were divided in 4 groups and treated with the use of traditional means without immunostimulating drugs; with immunoglobulins; with derinate and combination of both, respectively. The last treatment modality demonstrated maximal clinical efficacy. That is the decrease of the wound contamination period and inflammatory process; acceleration of granulation and epithelization.

[Prognostic significance of typical immune reactions in myocardial infarction].

Aim: To ascertain the role of typical reactions of the immune system in early prognostication of congestive cardiac failure (CCF) in patients with primary transmural anterior myocardial infarction (MI) in the postinfarction period.

Material And Methods: Typical immune reactions were studied for a year after the disease onset. A total of 228 males aged 40-60 years (mean age 53.

[Problem of specific and nonspecific factors in the induction and regulation of immunological reactions].

The functional unity of the specific and nonspecific mechanisms of immunological reactions has been shown on the basis of our own investigations and the published data. As revealed in this study, during the formation of immune response smooth transition from the nonspecific level to the specific one occurs. First, the factors of nonspecific protection are switched on, then intermediate reactions develop, further antibodies are synthesized, etc.
