[Dynamics of reserve possibilities of the cardiorespiratory system and pulmonary perfusion after surgical correction of congenital heart defects with arteriovenous blood output].

The dynamics of spiroveloergometric parameters and perfusion scintigraphy of the lungs with a postural test in 129 patients with congenital heart diseases were studied before and at different terms after surgical correction of the disease. It was established that main spiroergometric parameters were improved within the period from 3 to 6 months. However, normalization of physical working ability in the group of women took place about one year later than in men.

[Reserves of pulmonary ventilation and gas exchange in patients with pulmonary echinococcosis].

An examination of 33 patients has shown that complicated course of Echinococcosis of the lungs and their multiple lesions results in certain exhaustion of reserves of the external ventilation system. A conclusion is made on preference of performing organ-preserving and organ-sparing operations, on necessity of dispensary observations and physical rehabilitation of patients operated upon for complicated forms and multiple lesions of the lungs.

[Indicators of iron metabolism and cellular immunity in healthy children and in those with iron deficiency anemia in relation to ecological conditions].

The authors provide statistical data attesting to the fact that during the development of iron deficiency anemia in schoolchildren, the hematological, biochemical indicators characterizing iron metabolism in the body and phagocytic activity of peripheral blood leukocytes, one of the parameters of cellular immunity, undergo noticeable changes. It has been noted that in the regions where toxic chemicals are intensely used, both children with iron deficiency and normal ones demonstrate a significant decrease of phagocytic activity of leukocytes in spite of the fact that no quantitative alterations in iron metabolism are detectable in such a case.
