1. Biosynthesis and deposition of collagen, as well as DNA and total proteins, are increased in aortae of rats after 1, 3 and 6 weeks of hypertension. 2. The maximal increase in the rate of synthesis of collagen is observed within one week of hypertension when the stress to the arterial wall is maximal. 3. Reserpine administration prevents hypertension and inhibits the increase of collagen metabolism. 4. At any time of evolution of the hypertension, a linear positive correlation is found between the collagen content in the aorta and the level of blood pressure. 5. These data suggest that synthesis of matrix components by the arterial smooth-muscle cells is controlled by variation in the blood pressure level and is not a direct consequence of circulating humoral factors liberated by the ischaemic kidney.

Relapsing polychondritis is a disorder of unknown cause characterized by the destruction of cartilage. To test the hypothesis that immunologic mechanisms are involved in the pathogenesis of relapsing polychondritis, we analyzed the serum of 15 patients for the presence of antibodies to cartilage. Antibodies to Type II (cartilage) collagen were found in the serum of five patients at the time of acute symptoms. No antibodies were detected either to cartilage proteoglycan or to other collagen types. The antibodies were detected at the onset of the disease and their titers appeared to correlate with severity of disease. Circulating immune complexes were also detected in the serum of these patients. Our findings support an immunologic involvement in this condition. [less ▲]

The synthesis and deposition of collagen and other proteins has been measured in the aorta of the rat by radiolabeling in short term organ culture. Under these conditions, the synthesis of collagen and other proteins is linear for at least five hours. Autoradiography demonstrates a labeling in all cell layers and protein deposition in the extracellular matrix. Hypertension was induced by renal ischemia using Goldblatt's technique. The synthesis and deposition of collagen was stimulated in aorta from the first week of hypertension and in pregnancy, and was even more increased in hypertensive pregnant animals. Reserpine suppresses the rise in blood pressure in operated animals and prevents these modifications. [less ▲]

La technique d'analyse des surfaces par la spectrométrie des électrons Auger est décrite. Après un rappel historique de la découverte du mécanisme de réémission électronique par Auger, en 1925, les aspects physiques fondamentaux de la méthode sont présentés. La spectrométrie des électrons Auger fournit des spectres caractéristiques de transitions entre les niveaux discrets des atomes qui constituent une véritable signature atomique de la matière. Le volume détecté par l'analyse des électrons Auger excités par un faisceau d'électrons primaires est déterminé essentiellement par la profondeur d'éjection des électrons s'échappant de l'échantillon, dépendant elle-même de l'énergie de ces électrons. On peut ainsi montrer que les électrons Auger sont caractéristiques d'une profondeur de quelques Angströms seulement. Leur analyse permet donc de caractériser qualitativement et quantitativement la surface de matériaux solides. [less ▲]

Since 1960 marked changes have affected peripheral distribution in Europe.These modifications are due to the increase of new formulas such as superettes, supermarkets, food discount stores, hypermarkets, large specialised stores and shopping centres. In this article, we have tried to set out the main characteristics of these shops and compare their development in each country. We have furthermore tried to define the commercial and spatial repercussions of these complexes which, accordingly, have again brought up the problem of urbanistic and socio¬economic integration of large shopping stores in the periphery.

The aim of the work is twofold : to give the main intrinsic characterictics of self-service supermarkets and hypermarkets in the region of Liège and to examine their spatial insertion in the heart of this built-up area. Based on very precise surveys, it also tries to improve the methods used to study supermarkets and hypermarkets by putting forward new criteria and by perfecting certain types of analysis. Not only does it emphasize the big quantitative and qualitative features of these sales points but it also stresses the problem of localisation which is dealt with from three different points of view : structuration of the agglomeration, areas of insertion and accessibility by road and by bus.
