[The effect of direct x-ray contrast lymphography on pulmonary perfusion function]. / Vliianie priamoi rentgenokontrastnoi limfografii na sostoianie legochnoi perfuzii.

Overall twenty-five persons (8 males and 17 females) were enrolled in a study on the influence of straight radiopaque lymphography with an oily substance, on the condition of pulmonary microcirculation, as evidenced by perfusion pulmoscintigraphy. There was a significant decrease in the accumulation of 99m-Tc-macroaggregate (TCK-8) in lower portions of both lungs 24 hours after the lymphography and normal dispersal 10 days after the study made. The authors suggest that the radiopaque substance might stimulate the inflammatory processes in chronic nonspecific diseases of the lungs.

[Dynamics of rheological properties of the blood in patients with breast cancer during combined treatment]. / Dinamika reologicheskikh svoistv krovi bol'nykh rakom molochnoi zhelezy v protsesse kombinirovannogo lecheniia.

The paper is devoted to the results of investigation of blood rheological features (dynamic blood and plasma viscosity) in 70 breast cancer patients during combined therapy. The basal levels of dynamic blood viscosity indices in these patients were lower by 11.6% than in the control group of healthy women (p less than 0.05). During combined therapy after a course of gamma-beam therapy (in the small fractionation regimen for the 1st group and large fractionation regimen for the 2nd group) a further decrease of blood and plasma viscosity indices was observed, reaching their minimum values on the 14th day after radical mastectomy. In a long-term period of combined therapy (5 years--the 3rd group) dynamic blood and plasma viscosity indices remained below the control values and had no significant differences from the basal values in the 1st and 2nd groups. These shifts in rheological blood features during combined therapy of breast cancer were probably of favourable nature as complications (hypostatic pneumonia, thromboses, necroses of displaces of skin grafts) in the postoperative period were absent.

[Effect of adrenergic beta blockers on hemodynamics, diastolic relaxation and distensibility of left-ventricular myocardium in patients with ischemic heart disease]. / Vliianie adrenoblokatorov na gemodinamiku, diastolicheskoe rasslablenie i rastiazhimost' miokarda levogo zheludochka u bol'nykh ishemicheskoi bolezn'iu serdtsa.

Altogether 32 patients were investigated by catheterization of the left ventricular cavity with volume loading of 76% solution of verographin++ administered at 0.65 ml per kg body mass. beta-blockade with preliminary i.v. administration of 5 mg obsidan or 10 mg cordanum was shown to improve myocardial diastolic function as a result of improved myocardial distensibility in CHD patients.

[Roentgenography of the skin and subcutaneous tissue in postmastectomy edema of the upper extremities]. / Rentgenografiia kozhi i podkozhnoi kletchatki pri postmastéktomicheskom oteke verkhnei konechnosti.

The results of radiography of the forearm and shoulder soft tissues in 47 patients with postmastectomy syndrome before and after conservative treatment and in 6 controls made it possible to determine differences in x-ray imaging of a skin and subcutaneous fat layer in limb edema. These differences were determined by lymph flow disorders and the formation of a connective tissue component in subcutaneous fat and could be used for objective assessment of a degree of edema, determination of tactics of rehabilitation activities and assessment of their effectiveness.

[Mechanisms of compensation of disorders of acid-base status of the blood in patients with chronic anemia]. / Mekhanizmy kompensatsii narushenii kislotno-shchelochnogo sostoianiia krovi u bol'nykh khronicheskoi anemiei.

Altogether 228 patients with hereditary microspherocytic anemia (HMA), autoimmune hemolytic anemia (AIHA) and hypoplastic anemia (HA) were examined over time for the acid-base state of the arterial blood with the use of the pCO2-buffer bases coordinate system (BE/pCO2 and pCO2/BE diagrams). Prior to surgery the respiratory alkalosis was diagnosed in 60% of HMA patients (of these, 41.7% of patients had a decompensated alkalosis), in 61.7% of AIHA patients (73%), and in 69.7% of HA patients (82.1%). It is shown that the development in the patients of chronic respiratory alkalosis should be regarded as a compensatory mechanisms associated with hemic hypoxia complicated by arterial hypoxemia. During splenectomy, there was an increase in the incidence of decompensated respiratory alkalosis. Mixed respiratory and metabolic alkalosis occurred in 8.3% of AIHA patients and in 19.6% of HA patients because of artificial ventilation of the lungs. Two hours after operation compensated metabolic acytosis was identified in 72% of HMA patients, in 33.3% of AIHA patients, and in 33.9% of HA patients. Twenty-four hours following operation the patients of all the groups had arterial hypoxemia and hypocapnia. In view of this fact the blood acid-base state was determined by the presence of respiratory alkalosis: in 47.5% of patients with HMA, in 60% of patients with AIHA, and in 54% of patients with HA. Analysis of the BE/pCO2 diagram demonstrated that in 2/3 of the patients with HMA and AIHA and in all the patients with HA, respiratory alkalosis was decompensated. It was established that electrolyte imbalance detected in the patients interfered with metabolic compensation for chronic respiratory alkalosis.(ABSTRACT TRUNCATED AT 250 WORDS)
