[Gastric juice proteins in neoplastic diseases with and without involvement of the digestive system].

Gastric juice proteins were studied in normal subjects and persons with gastro-intestinal, lung and pancreatic neoplasia and chronic systemic lymphopathy and haemoblastosis, using cellulose acetate and acrylamide gel electrophoresis of the freeze-dried dialyaste and chromatography of the amino acids obtained from the hydrolysate. Definite evidence was gathered of both qualitative and quantitative changes in protein fractions. Patterns varied from one group of subjects to another, though the basic picture was the same in both intestinal and extra-intestinal conditions. An effective relationship between the diseases considered is postulated and the data are interpreted with a view to evolving other points for further investigation.

[Analysis of membrane proteins in pernicious anemia and various primary and secondary erythropathies].

A study of membrane proteins in pernicious anaemia and other haemolitic and anhaemolytic erythropathies is reported. Cellulose acetate and acrylamide gel electrophoresis was carried out and acid, neutral and basic amino acid contents were determined. Relatively specific alterations were noted. Chromatographic analysis of the amino acids suggested that in pernicious anaemia, as in other conditions, structural changes take place in the red cell membrane, though these may be confined to certain sectors. A constant alteration related to the concomitance or otherwise of erythrocyte hyperhaemolysis, however, could not be discerned.

[Erythrocyte changes of membrane proteins in some hemoglobinopathies].

The electrophoretic behaviour of red cell membrane proteins was studied in thalassaemia major and minor and in sickle-cell anaemia. Protein amino acid composition was also determined following hot hydrolysis of the stromas. Experiments with various solubilisation methods, electrophoresis supports and buffers showed certain changes in these three diseases, accompanied by alterations of the percent ratio of some amino acids.
