[The value of CT in diagnosis of low back pain syndromes]. / Wartosc KT w diagnostyce zespolów bólowych ledzwiowo- krzyzowych.

The authors discuss results of CT studies in 300 patients with low back pain syndromes. Apart from herniated discs (56.3% of cases) pain could be often explained by degenerative changes of facet joints or bulging disc leading to spinal canal stenosis. In the group of patients operated on due to disc herniation correlation between CT and surgical results has 85.4%. In the authors' opinion CT is an effective, non-invasive diagnostic method in patients with low back pain syndromes.

[Diagnostic evaluation of HLA sera obtained as a result of cooperation between the Institute of Hematology and blood donation stations]. / Ocena diagnostyczna surowic ukladu HLA uzyskiwanych we wspólpracy Instytutu Hematologii ze stacjami krwiodawstwa.

The aim of the cooperation between the Laboratory of Leucocyte and Platelet Immunology, Institute of Haematology and Blood Donation Stations was typing of anti-HLA sera from the blood of pregnant women. During 18 months of this cooperation 477 sera were studied. In 255 sera (53.1%) lymphocytotoxic antibodies were demonstrated and their specificity was determined. The types anti-HLA sera will be used for determination of HLA antigens in blood donors donating blood in the Stations. The results of these determinations, technical problems and conclusions drawn from this cooperation are discussed. Continuation of this cooperation will contribute to further limitation of the import of anti-HLA sera.
