[Discriminant-analytic structure-effect relationship of qualitative biological data. Virostatic effect of isatin-beta-isothiosemicarbazones].

"Yes/No" results from the plaque-diffusion inhibition test concerning the virostatic activity of substituted isatin-beta-isothiosemicarbazones against mengo- and vaccinia-viruses can be described discriminant analytically by means of simple substituent constants. The discriminant analysis permits quantitative structure-activity analysis of qualitative and semi-quantitative test data, thus offering a chance for theoretical synthesis optimization already at the level of rough screening.

[Anistreplase. Pharmacology and biological data].

Anistreplase is a second generation thrombolytic agent, an equimolecular streptokinase lys-plasminogen complex the active site of which is temporarily blocked by a p-anisoyle group. Acylation enables the drug to be administered as a bolus intravenous injection over 2 to 5 minutes, and it protects anistreplase against circulating inhibitors, hence a plasma elimination half-life of 90 minutes. Deacylation is slow and progressive (deacylation half-life: 105 minutes), and it begins as soon as the product is injected. It reduces the hypotensive effect of streptokinase, permits a prolonged action in the thrombus and limits the risk of reocclusion. Using lys-plasminogen increases the affinity of the drug for fibrin and potentiates its accumulation and retention in the thrombus. In vitro studies have shown that the affinity of anistreplase for fibrin is similar to that of t-PA. In doses used for myocardial infarction, anistreplase induces a pronounced fibrinogenolysis. The effectiveness of the drug has been demonstrated on numerous animal models and subsequently by clinical trials.

[Histological study of the bone marrow in 96 cases of Waldenstrom's macroglobulinemia. An evaluation with clinical, haematological and biological data (author's transl)].

Bone marrow biopsy in Waldenstrom's macroglobulinemia shows three types of lesions: lympho-plasmocytic and reticular infiltration, which is the most common, reticular infiltration, and aplastic marrow, more seldom. In all cases the reticulinic network is increased and thickened. These lesions are diffuse or nodular. Diffuse infiltration is more severe and has a median duration of 62 months instead of 82 months in nodular infiltration.

[Clinical and biological data affecting insulin-dependent diabetes in French children at the time of its diagnosis].

In order to characterize Type I diabetes at its clinical onset in French children, we studied HLA-DR alleles, beta-cell function and autoantibodies to islet-cell antigens and insulin in 115 patients aged 1.8-17 years. Beta-cell function was markedly impaired, but with an unexpectedly wide range of individual variations. These variations showed no correlation with HLA alleles or circulating autoantibodies, as opposed to observations made by others. Age, however, had a clear influence on the degree of impairment of residual insulin secretion, the younger children having the more deteriorated beta-cell secretory capacity conditioning the severity of clinical manifestations (weight loss, ketonuria, ketoacidosis) and initial hyperglycemia.
