[Detection of pathology of the urinary system in students during preventive mass screening].

Screening tests including the questionnaire method, urine analysis and radiorenography were used during mass screening of 1330 students. Comparison of the results of the first two methods showed a good informative value of the questionnaire method for the detection of pathology of the kidneys and urinary tracts. Radiorenography performed in 106 students with the detected nephrological symptom complex (risk group) revealed some changes practically in every other "risk group" student.

[Use of liposome-bound x-ray contrast substances for the diagnosis of splenic lesions in generalized lymphoma in SJL/J mice].

An X-ray procedure for diagnosis of splenic lesions in sjl/j mice with generalized lymphoma, using verographin contained in liposomes, is discussed. Intravenous injections of the preparation were followed by changes in X-ray pictures of the spleen in 9 out of 21 mice aged 11-13 weeks which were interpreted as total or local lesions. The X-ray diagnoses were confirmed by histological examination.
