[The significance of radiculography and resonance tomography in the diagnosis and treatment of lumbar discopathy]. / Znaczenie radykulografii i tomografii rezonansowej w rozpoznawaniu i leczeniu dyskopatii ledzwiowej.

The subject of the study was an assessment of the usefulness of radiculography and resonance tomography in the diagnosis of lumbar discopathy. The study was carried out in 100 cases of lumbar discopathy treated at the Department of Spondyloneurosurgery Institute of Rheumatology in Warsaw. Both radiculography and resonance tomography were found to be of equal diagnostic value in the verification of the clinical symptoms of this discopathy. The detection rate of lumbar discopathy by both methods was much higher than based on clinical symptomatology alone. The use of both methods was not equivalent diagnostically (often they replace one another, but often also they supplement one another), and for that reason combined examination by both methods is frequently of high importance in practice, when the line of management is to be set down.

[The assessment of therapeutic effectiveness of paravertebral blockades in patients with painful radicular syndromes in discopathy and in lumbar spine spondylosis]. / Ocena efektywnosci terapeutycznej blokad przykregoslupowych u chorych z zespolami bólowo-korzeniowymi w przebiegu dyskopatii i zmian zwyrodnieniowych ledzwiowego odcinka kregoslupa.

A group of 103 patients were examined for radicular painful syndromes in lumbar discopathy and lumbar spondylosis. Fifty-eight were treated by placing them in spine-decompressing position, traction and therapeutic exercises. The group of 45 patients had additionally paravertebral blockade (steroid + a local anaesthetic). In the blockade group the therapeutic effects were better, with rapid reduction of acute pain, with wellbeing improvement and better comfort, which facilitated further stages of the treatment. This made possible shortening of hospital stay by 20%, on average, as compared with the group without blockade. In patients with shorter lasting radicular pains (below 2 months) the results after paravertebral blockade were significantly better than in cases with longer duration of pains (2-6 months).

Use of amylum derivatives for isolation of amylolytic enzymes.

In a leading article literature is reviewed concerning isolation of amylolytic enzymes by adsorption on differently modified starches, resp. on other adsorbents. DEAE amylum, DEAHP amylum and DEAE-Sephadex A 25 were found to be most suitable adsorbents. The other adsorbents examined did not reach claimed parameters.

Isolation of amylolytic system of Aspergillus oryzae by sorption on DEAHP amylum.

Conditions of effective sorption of amylolytic enzyme from a solution or from fermentative liquid on DEAHP amylum were studied. Isolating action is in a direct dependence on the relation between activity and amount of DEAHP amylum, the curve of this dependence was illustrated. The enzyme can be released by elution or adsorbate can be used in a pulverised from. In the conclusion of the work laboratory isolation technique is described.

Isolation of amylolytic system of Aspergillus oryzae on DEAE amylum.

Studying isolation technique with DEAE amylum the method was found to be suitable for isolation of alpha-amylase. After determination of optimal conditions sorption curves were illustrated, from which the amount of DEAE amylum needed for 100% enzyme sorption from solutions of various activity and origin can be calculated. Preparation obtained shows high temperature stability and can be used in food industry and agriculture or after its elution in pharmacy. At the end of the paper laboratory isolation technique is described.
