[The use of echo- and scintigraphic study of the biliary system in chronic cholecystitis].

Data are reported of a study of the functional state of the biliary in 50 patients with chronic cholecystitis by means of complex employment of dynamic echo- and cholecystography and dynamic computerized gamma-hepatobilioscintigraphy. It was found that dynamic echo- and cholecystography proved highly efficient indicating that ultrasound tomography is of importance not only the diagnosis of structural but also functional disorders in cholecystitis, for the choice of optimal tactics and evaluation of the efficacy of therapeutic measures excluding radiation treatment.

[Use of computers in the roentgenological diagnosis of gynecologic diseases].

The authors analyze the use of computers in x-ray examinations of gynecologic patients. X-ray signs of infertility, endometritis, tuberculosis, myoma, malignant tumors, etc. were formalized.

[Diagnostic possibilities of roentgeno-endoscopic and morphologic methods of examining the colon in nonspecific colitis].

The paper is concerned with comparative assessment of the diagnostic potentialities of the x-ray, endoscopic and pathomorphological methods of investigation. The results of the examination of 100 patients operated upon for nonspecific ulcerative colitis (54) and Crohn's disease (46) were analyzed. The advantages of these methods were demonstrated.

[A gamma scintigraphic assessment of blood supply of the hip joint in Perthes disease].

In order to specify the peculiarities of the blood supply of the hip joint in Perthes' disease the authors carried out gamma scintigraphy by 99m Tc-pyrophosphate in 34 children. Patients with roentgenologically confirmed diagnosis of Perthes' disease at various stages as well as those in whom Perthes' disease was suspected, but convincing roentgenologic changes were absent, were examined. The data of scintigraphy and roentgenography were compared.

[Diagnostic possibilities of static gamma-scintigraphy using 99mTc pyrophosphate and Tc 99m phosphate in children with glomerulo nephritis].

Children with nephrotic glomerulonephritis were examined for incorporation of 99mTc-pyrophosphate and 99mTc-phosphone. The relationship was discovered between the accumulation of the radiopharmaceutical drug and the sensitivity to glucocorticoids used in the pathogenetic treatment. Accumulation of the drug in the course of the treatment documents the presence of complete, partial remission or the disease activity.

[Determination of the sensitivity to glucocorticoids in vitro].

A modified method for the determination of glucocorticoid receptors in human lymphocytes is suggested. The principal distinction of the method is standardization by the lymphocyte count in a sample (1 mln) and the labeled hormone concentration. The modification saves time and money, limits the range of the data variations, and makes use of a lesser volume of blood.

[Clinico-radiological assessment of the effectiveness of pathogenetic therapy in glomerulonephritis in children].

Liver scintigraphy and hepatobiliary scintigraphy were employed for the assessment of kidney and liver function in children with glomerulonephritis at the stages of pathogenetic therapy with chlorambucil and prednisolone. Noticeable disturbance of nephron and hepatocytic function at the climax of clinical manifestations of the nephrotic syndrome was established. The use of maximum and maintenance doses of prednisolone and chlorambucil resulted in significant improvement of clinical and radionuclide indices.

[Radionuclide diagnosis of acute pyelonephritis].

Nephroscintigraphy using a 67Ga-citrate complex and 99mTc-pyrophosphate was performed in 88 patients with acute pyelonephritis. Nuclide hyperfixation was revealed in 97.8% of the cases.

[Radionuclide evaluation of the function of the operated kidneys].

Altogether 68 patients were examined in early and late periods after operations on the kidneys. Function of the operated kidney was checked up by the results of two-indicator renal scintigraphy with 99mTc-DTPA and 131I-hippuran. When the kidney preserved its secretory capability and the suppression of organ function was caused by inhibited urine passage via the upper urinary tract, therapy aimed at the restoration of the kidney integrity and the elimination of the urine discharge obstruction, resulted in a rapid and complete recovery of all renal functions.

[Effect of parenteral nitrogen feeding on the free amino acid composition of the blood serum and liver tissue in irradiated rats].

A considerable change in the free amino acid composition of blood serum and hepatic tissue was noted on the 7th and 14th days following total-body X-irradiation of rats with a dose of 2.9 Gy. The total free amino acid content of blood serum increased and that of hepatic tissue decreased by 85% (on an average) as compared to the intact controls.
