[New possibilities in prevention and correction of postoperative suppurative-septic complications and multiple organ failure in oncological surgery].

The functional status of the oxidative-antioxidative system was studied in 72 patients after vast cancer operations. Traditional surgical treatment and its combination with intraoperative irradiation were shown to lead to tense antioxidative defense and to suppressed T-cell immunity and to call for antioxidative and immunomodulating therapy. High intraoperative blood loss complicated by hemorrhagic shock injured the oxidative-antioxidative system greatly.

Impact of HIV-positive sera on the functional activity of polymorphonuclear neutrophils from healthy donors.

The impact of the sera from 64 HIV-1-infected patients on the functional activity of polymorphonuclear neutrophils (PMN) from 9 healthy donors was investigated. Augmentation of PMN oxygen radical production in the presence of sera from HIV-infected patients (PMN chemiluminescence) was demonstrated. This enhancement was connected with intracellular generation of chemiluminescence (CL).

Mononuclear cells from HIV-infected patients produce factors which enhance functional activity of polymorphonuclear neutrophils from healthy subjects.

The influence of mononuclear cell supernatants (MNCS) from nine healthy donors and 35 HIV-infected patients (17 with lymphoadenopathy syndrome (LAS), 15 with ARC and three with AIDS) on functional activity of polymorphonuclear neutrophils (PMN) from healthy donors was investigated. MNC after short-term cultivation (24 h) produced factors which enhanced chemiluminescence (CL) and chemotaxis of PMN. This augmentation did not depend on stimulation of MNC by mitogens (lipopolysaccharide Escherichia coli (LPS) and concanavalin A (Con A)) or on activation of PMN by FMLP.
