[Evaluation of coagulation factor XIII. Critical study of the different techniques used (author's transl)].

A critical study of various techniques of factor XIII determination was performed. The method using dansyl-cadaverin seems to be the most sensitive one but not easily usable in routine tests. The biological techniques using factor XIII-free fibrinogen (screening test and classical test) are satisfactory in clinical trials but are not sensitive for the detection of moderate deficiency of factor XIII. The immunological tests used are the electro-immuno-diffusion test and the test of the consumption of an anti-serum. However, only the antibody directed against the sub unit. A must be used. All these techniques were performed in acquired deficiency of factor XIII and a good correlation was obtained. However, in factor XIII congenital deficiency, we propose to associate a biological assay and the antigenic determination of factor XIII in order to detect a possible abnormal factor XIII.

[Platelet functions in diabetes with angiopathy (author's transl)].

Platelet functions studied in 163 unselected diabetics compared with 163 controls had the following characteristics: hyperagregation induced by ADP (1.2 muM and 0.6 muM), delayed platelet disagregation (ADP: 0.6 muM), normal agregation in the presence of collagen and thrombin. Platelet hyperagregation induced by ADP was marked in both sexes in cases of retinopathy and in women after the age of 50. By contrast, no correlation was demonstrated between the degree of hyperagregation and age, weight, the duration of diabetes, blood glucose control, lipid profile, vascular complications other than retinopathy and the nature of treatment.

[The detection of soluble fibrin complexes by a haemagglutination test. Clinical applications (author's transl)].

Testing for soluble fibrin complexes was performed using a sensitive and reliable haemagglutination assay, with red cells sensitized by fibrin monomers. The principle is based on the fact that the monomers linked to red cells and induce their agglutination. This test, used in clinical trials, has revealed the presence of soluble complexes in every confirmed case of acute DIC, but also in Chronic DIC where diagnosis is difficult to establish (negative ethanol gelation test, normal or sub-normal levels of fibrin breakdown products). In Cirrhosis of the liver, the test gives positive results in a non negligible number of cases. Several hypotheses are made to explain why in certain confirmed cases of DIC, low fibrin breakdown products levels are found.

Glycosylated haemoglobin concentrations and clinitest results in insulin-dependent diabetes.

In 11 insulin-dependent diabetic outpatients, haemoglobin AIc (HbAIc) was measured by an electrofocusing method. Diabetic control was evaluated by the semiquantitative urine test for sugar, 'Clinitest', three times a day every day in the 8 weeks before the HbAIc determination. 24-hour glycosuria and fasting and postprandial blood-glucose levels were measured one to five times during this period. The HbAIc concentration correlated highly with the semi-quantitative urinary-sugar-concentration index but not with the other parameters.

Human platelet fibrinogen: a protein different from plasma fibrinogen.

Fibrinogen has been purified from normal and dysfibrinogenemia Metz plasmas, and from normal and from the patient's platelets. There are differences in the pattern of disc polyacrylamide gel electrophoresis between normal plasma and normal platelet fibrinogens, but the migration of the A alpha chain is similar. The abnormality of the electrophoretic mobility of the A alpha chain of plasma fibrinogen from Metz dysfibrinogenemia is not found in platelet fibrinogen of this patient. This result clearly establishes that platelet fibrinogen is a different protein from plasma fibrinogen.
