Aim: To examine frequency and characteristic features of complications arising in administration of domestic antilymphocytic globulin (ALG) in patients with aplastic anemia (AA)., Material and Methods: From 1980 to 2000 125 patients with AA were treated with ALG made in Russia. Two and three courses of ALG were performed in 25 and 8 patients, respectively., Results: The treatment was complicated most often with allergic reactions (AR) observed in 42.4% patients, hemorrhagic syndrome (HS) and infectious complications (IC). Goat ALG was more allergic than rabbit ALG (46.2 vs 34.6%, respectively). If the second course was made with ALG of the same kind, AR occurred in 37.5% patients while ALG of the different kind produced complications only in 11.8% patients. HS was recorded in 37.3% patients, its frequency was unrelated to ALG kind and was not severe (71.2%). IC occurred in 16.5% patients, their occurrence was also unrelated to the ALG kind and were of the first degree in 63.6%., Conclusion: Domestic ALG often results in AR. To reduce frequency and severity of complications in ALG treatment, it is recommended to use long intravenous infusions (12-18 h) and change ALG kind in subsequent ALG courses.

A membrane stabilizing effect of endobronchial laser therapy and antioxidative drugs piracetam and solcoseril was studied in 83 patients with chronic bronchitis. Malonic dialdehyde was measured to evaluate effects of this treatment on cellular and humoral immunity, blood coagulation and lipid peroxidation. It was found that the addition of membrane stabilizers to standard therapy of chronic bronchitis lowered malonic dialdehyde concentrations while the addition of the stabilizers and endobronchial laser therapy relieved clinical symptoms earlier, improved parameters of immunity, hemostasis and lipid peroxidation.

Under study were the state of the hemostasis system, the level of endogenous intoxication and anti-infectional defense in 63 patients with complicated carcinoma of the gastro-intestinal tract (GIT). It was established that the patients had the syndrome of disseminated intravascular coagulation (DIC) of blood which at first was of local character. Acute complications of carcinoma of GIT, first of all purulent peritonitis and profuse gastro-intestinal bleedings, aggravate endotoxicosis and facilitate the development of the acute DIC syndrome. A conception of the development of the intoxicative DIC syndrome is presented and proposed are informative methods of the assessment of hemostasis in emergency surgery of carcinoma of the GIT.

DIC-syndrome frequently associated with anemia is one of rheumatoid arthritis complications which runs latently in the presence of hypercoagulation and low fibrinolytic activity. The development of DIC syndrome in the above patients correlates with the process activity, pattern of the disease, is independent of rheumatoid arthritis stage and duration, the patients' age, immunological and serological characteristics. Concentrations of circulating immune complexes and DIC-syndrome are related in rheumatoid arthritis patients with anemia.

A study was made of changes in functional status of complementary system in 42 patients with chronic renal failure on programmed hemodialysis. Early stages of hemodialysis were accompanied by short-term and reversible activation of complementary system. 100 sessions were followed by complement depression. Complement system was found to be involved in two pathogenetic mechanisms of respiratory insufficiency: block of pulmonary microcirculation by leukocytic aggregates and DIC syndrome associated with microthrombosis of the lesser circulation vessels. To manage the above complications, plasmapheresis is advocated.
