[A contribution to the early diagnosis and differential diagnosis of bladder neoplasms by means of immunological methods].

According to the present examinations it is pretty probable that already in early histological forms of the carcinoma of the urinary bladder the EM-test is able to indicate immunologically malignity, i.e. that the papillary non-infiltrating carcinoma of the transitional cell as well as the carcinoma in situ of the urinary bladder (23) also immunologically behave like tumors of the bladder.

Urinary fibrin degradation products--a three year comparative study.

Urinary fibrin degradation products (FDP) were determined by Merskey's passive haemagglutination test in 115 patients with biopsy proven chronic proliferative glomerulonephritis (GN), 94 with urinary tract infection (UTI), and 23 transplanted patients. The active GN values (12.3 microgram/ml) are significantly higher than those for latent GN (0.

A contribution to immunological tumour diagnostics in urology.

Fifty-four patients with malignant and other diseases of the urinary bladder and the prostate were examined for lymphocyte sensitization by means of electrophoretic mobility test (EM test). In this antigens from brain tissue (EF) and from malignomas of kidney, urinary bladder and prostate were used. Positive HEP values were obtained in 40 patients out of 42 with malignant tumours and in 5 patients out of 12 with other kidney diseases.

[Immunodiagnosis of urologic tumors].

In 42 patients with malignant and benign diseases of the kidney, the urinary bladder and the prostate the sensitization of the lymphocytes was investigated in the cell electrophoresis mobility test. In these cases human encephalitogenic protein and tumour-associated antigens from malignomas of kidney, urinary bladder and prostate were used as antigen. When using human encephalitogenic protein 3 "falsely positive" and 2 "falsely negative" results were got, whereas, when using the corresponding tumour-associated antigens in the cell electrophoresis mobility test in every case the histologically ascertained tumour diagnosis could be confirmed.

[Isoelectric focusing studies of synovial fluid in rheumatoid arthritis].

Synovial fluids obtained at operation in several different diseases were studied by means of isoelectrical focussing. All the punctates of patients with rheumatoid arthritis showed bands which migrated towards the cathode and which were not found in synovial fluid from other diseases, except in 2 meniscus lesions. In the range of pH 6.
