[Study of present possibilities of interlaboratory standardisation of the prothrombin time (author's transl)].
The graphs or tables proposed by the manufacturer of reagents, the Thivolle straight lines suggested by Raby or, since 1977, Loeliger's procedure, are three possibilities offered to biologists to transform the prothrombin time into prothrombin concentrations expressed as a percentage. We have studied the possibility of interlaboratory standardisation in the case of patients treated with coumarin derivatives: firstly with the same thromboplastin under various conditions of use; secondly with five different thromboplastins under identical conditions (choosing arbitrarily one of the reagents as reference). Loeliger's procedure is the one which permits the best standardisation, but its practical application seems difficult. It seems to us that before carrying out this standardisation between laboratories, one should indicate, with the result found for the patient, the area of therapeutic activity of the thromboplastin used, as suggested by Ducker and Marbet in 1977 (these authors determined this area of therapeutic activity for 13 different reagents used in Switzerland).

[Hereditary bisalbuminemia. Study of a new familial case in France (author's transl)].
A case of bisalbuminemia of slow type was discovered in a 41 year old woman with obesity, diabetes mellitus and hypertension. This abnormality was discovered in six other members of the family and was thus hereditary. After a description of the laboratory tests used, the various forms of bisalbuminemia are described together with the circumstances of onset of the acquired forms, the biochemical and metabolic characteristics of the hereditary forms and their mode of transmission. Bisalbumin is present in all races. The mother of our case was of Italian origin, which permitted us to classify this case with others of Italian origin.

[Carcinoembryonic antigen. Evaluation in intestinal lavage fluids and in the tissue of colorectal tumors].
Carcinoembryonic antigen in pre-operative or pre-endoscopic intestinal lavage rinsing fluids was assayed in 21 healthy subjects, 15 presenting polyps and 12 presenting colorectal cancer. Comparison of the results with those of histological and immunohistological studies showed that this assay did not allow detection of intestinal cancer or evaluation of its developmental stage.
