First main series of transition elements with atomic numbers from 22 to 29, found in air pollution and detected in the plants from Tajikistan areas.

According to several reports, the presence of transition metal elements in the atmosphere was associated with adverse health effects. The purpose of this investigation was to analyze the presence of transition metal particles with atomic numbers 22-29 on some medicinal plants (n = 22) from various regions of the Republic of Tajikistan and their content in the atmosphere. Samples (n = 43) of individual plant organs, such as seeds, flowers, leaves, trunks, and plant roots, were examined for their elemental composition using X-ray fluorescence analysis.

[Deposition of 51Cr-labeled donor platelets in health and myelosuppressive thrombocytopenias].

Aim: To study the deposition of donor platelets (DP) in myelosuppressive thrombocytopenia (TP) in patients with acute leukemia (AL) or lymphosarcoma (LSA), by using a radionuclide label (51Cr) for DP.

Subjects And Methods: Complex clinical, hematological and radionuclide studies were conducted in 63 patients divided into 3 groups: 1) 7 healthy volunteers (a control group); 2) 37 patients with AL; 3) 19 patients with LSA.

Results: Changes were found in the deposition of labeled DPs used to prevent and treat hemorrhagic syndrome in myelosuppressive TP in patients with AL or LSA.

[The survival and sequestration of transfused donor platelets in cytostatic cytopenias].

Aim: To study the survival and sequestration of transfused donor platelets labeled with 51Cr in patients with acute leukemia (AL).

Subjects And Methods: Seven donor volunteers and 39 patients with different forms with AL at various stages of polychemotherapy (PCT) were examined. Cytostatic therapy was accompanied by 51Cr-labeled platelet concentrate (PC) transfusions.

[Diagnosis of early manifestations of myocardial dysfunction at early stages of antitumor treatment in patients with lymphogranulomatosis and lymphosarcomas].

Aim: To comparatively assess the capabilities of currently available instrumental studies in the diagnosis of early cardiac performance changes in patients with lymph tumors at different stages of treatment and to study the myocardial histomorphological pattern in relation to the intensity of the therapy performed (as evidenced by sectional studies).

Materials And Methods: 44 patients, including 26 with various types of lymphogranulomatosis (LGM) and 18 with lymphosarcomas were examined at different stages of antitumor treatment. Radionuclide equilibrium ventriculography (REVG), echocardiography (EchoCG), and electrocardiography (ECG) were used.

[Gamma-scintigraphy with Ga-67 citrate in differential diagnosis of residual tumors in lymphogranulomatosis and lymphosarcoma].

Aim: To study informative and diagnostic efficacy of quantitative evaluation of the results of gamma-scintigraphy in patients with lymphogranulomatosis and lymphosarcoma with prevalent mediastinal and pulmonary lesions.

Material And Methods: 100 patients with verified lymphogranulematosis were studied: 67 with lymphosarcoma and 33 with mediastinal involvement. The mediastinal tumor monitoring was made before therapy, in complete clinicohematological remission, in progression using a complex of radio-, clinicohematological, histomorphological and radionuclide methods.

[The diagnosis of a hemorrhagic syndrome in chronic myeloleukemia].

A study was performed of 40 patients with chronic myeloid leukemia. Clinicohematological, radionuclide (51CR), electron-microscopic methods and examinations of plasma and platelet components of hemostasis were applied to elucidate stage-specific relationships between functional-morphological changes in platelets and early manifestations of hemorrhagic syndrome (HS). The latter was directly related to platelets functional activity and their ultrastructure.

[Latent gastro-intestinal hemorrhages as symptoms of hemorrhagic syndrome in acute leukemia].

A clinicoradiologic investigation of latent gastrointestinal hemorrhages was conducted in acute leukemia patients with the use of 51Cr. A total of 26 patients suffering from varying forms of leukemia with no external hemorrhages were investigated. Latent gastrointestinal hemorrhages were detected in 50% of the patients.

[Quantitative evaluation of latent gastrointestinal hemorrhage in patients with iron deficiency anemia (preliminary report)].

Radiologic investigation of concealed gastro-intestinal hemorrhage with 51Cr was conducted for its detection and quantitative estimation in 102 patients with iron-deficiency anemia (IDA), loss of blood from the digestive tract was detected in 52 of them. A definite relationship was noted between the volume of hemorrhage and the disease responsible for the development of IDA. Moderate hemorrhage from 2.
