Thirty hospitalized, severely obese patients (40 +/- 2 yr, 82 +/- 4 percent weight excess) were submitted to a 13-d protein-supplemented fast (PSF) with 70 g milk proteins/d (1.26 MJ or 300 kcal). The mean weight loss during PSF was 5.4 +/- 0.3 kg corresponding to 422 +/- 39 g/d. Comparison of the urinary nitrogen excretion with daily protein intake revealed that the nitrogen balance was equilibrated during PSF. Blood glucose decreased moderately but significantly during the whole PSF period whereas plasma insulin was only reduced during the first 9 d and tended to rise thereafter. Plasma FFA increased rapidly and remained elevated until the end of the study (+ 60 per cent); serum total cholesterol and plasma triglycerides showed a 26 and a 35 per cent decrease respectively. Basal plasma glucagon was slightly increased. Due to the low sodium intake (42 mmol/d) urinary sodium excretion dropped rapidly. Simultaneously both systolic (-13 mmHg) and diastolic (-7 mmHg) arterial blood pressure decreased significantly. The biological tolerance was good: metabolic acidosis was prevented with sodium bicarbonate, excessive rise in serum uric acid was corrected with allopurinol and a marked decrease in serum potassium was avoided with an appropriate dose of spironolactone. Twenty-six patients could be weighed 6 to 15 months after PSF: 12 showed a further weight reduction (6.6 +/- 1.6 kg) and seven a discrete weight gain (1.0 +/- 0.4 kg). Thus, PSF was well accepted and was profitable in 19 out of our 30 patients. It should be restricted to cases of severe and refractory obesity and performed under careful medical supervision.

We measured the c.s.f. and serum creatine kinase activities in the first hours following the trauma, for 24 severe head injury patients. We found a good correlation between total CK and CKBB isoenzymes levels in the c.s.f. only. The c.s.f. values are a quantitative index of brain dysfunction assessed by the Liege coma scale, associating the Glasgow coma scale and the study of the brain stem reflexes. There is no relationship between CK activity and intracranial pressure. [less ▲]

Established essential HTA is considered to result from the influence of both heredity and environment. Among the environmental factors, dietetary sodium has been proposed to play an important role inducing an increase in peripheral vascular resistance. The primary abnormality in essential HTA could consist in a genetically transmitted membrane defect impairing the cellular mechanisms which normally compensate a sodium load. The analysis of this defect implies more certainly elucidation of the effects of sodium ions at the blood vessel musculature level. But smooth muscle cells are unfortunately rather inaccessible. Yet it would be of great interest to dispose of a simple laboratory test to detect primary HTA. Therefore, on account of their availability and ease of manipulation, blood cells have been studied and already twenty years ago, LOSSE (12) recorded an increase of the intracellular sodium concentration in erythrocytes of hypertensive patients. Since then, different groups described different abnormalities' in the movement of ions across the blood cells membranes. Indeed modifications of the passive permeability (11, 12, 13), the sodium potassium pump (1, 5, 14), the sodium lithium countertransport (2, 7, 18) and the sodium potassium cotransport (3, 8, 9,10) have been successively demonstrated. GARAY et al. (9,10,11) observed a decrease in this last transport system for essential hypertensives and a high proportion of their young offspring. Conversely for normotensive patients, without a family history of HTA or in secondary hypertensives, a normal cotransport was found. The finding of an abnormal cotransport in a young normotensive may thus elicit preventive measures such as appropriate sodium diet, prevention of excessive weight gain, clinical follow up during oral contraception or pregnancy. The first observations showed a very clearcut difference between the two populations. However, many authors using the same test procedure, found a large overlap suggesting the measurement of this cotransport will not prove useful to discriminate primary HTA. However, the methodology was not always the same and difference could also arise from the definition of normal control groups which needed to be carefully selected. Thus in this study, we would evaluate the modification of the Na+ K+ cotransport in primary and secondary HTA, using strictly the experimental methodology originally described by GARAY et al. (9, 10). Afterwards, it would be interesting to study the effect of obesity, diabetes and the menstrual cycles on this transport system. [less ▲]

The exocellular beta-lactamase (penicillin amido-beta-lactamhydrolase, EC 3.5.2.6) of Actinomadura R39 consists of one single polypeptide chain of molecular weight about 15 200. It exhibits a highly asymmetrical shape, has a low isoelectric point (at pH 5.0) and contains about 9.3% (w/w) of a polydeoxyribonucleotide with which it forms a rather stable complex. Removal of a substantial amount of this deoxyribonucleotide by treatment with DNAase I has no effect on the enzyme activity. The beta-lactamase has a wide spectrum of activity. Penicillins and delta 3-cephalosporins can be either good or poor substrates. Oxacillin, which is a poor substrate of most beta-lactamases from Gram-positive bacteria, is a good substrate of the beta-lactamase of Actinomadura R39. Its best substrate, however, is nitrocefin (kcat/Km: 2300 000 M-1.s-1; catalytic centre activity: 210 s-1). The kcat/Km values observed with some penicillins and delta 3-cephalosporins are similar to the values of the bimolecular rate constants that govern the formation of the acyl-enzyme intermediates between these antibiotics and the serine D-alanyl-D-alanine peptidase that is also secreted by the same strain Actinomadura R39. Such a relationship, however, is not observed with all the beta-lactam compounds tested. [less ▲]

Eighteen patients who survived an acute myocardial infarction were found to have a normal coronary arteriogram. Seven patients were younger than 35 years and six were female. The myocardial infarction was nontransmural in 11 cases. The mean follow-up was 21.6 months. Eleven patients developed residual chest pain at rest early after myocardial infarction. One, treated by beta-blockers, suffered a recurrent myocardial infarction. Eight became asymptomatic, and two improved under antispastic therapy. Another patient developed a severe form of variant angina three months after myocardial infarction; she died following plexectomy. Finally, two patients experienced rare episodes of angina at rest. The stress ECG was negative in all cases. Provocative test for spasm was positive in three out of nine patients. Diffuse narrowing associated with chest pain was demostrated in two patients at angiography. Thus, myocardial infarction and subsequent normal coronary angiogram are mainly found in young female patients, and infarction is often nontransmural. Clinical evidence of vasospastic phenomena and increased vasomotor tone are found in most patients. Whenever residual chest pain is controlled by antispastic therapy, the follow-up course seems benign. [less ▲]

An analysis of methods of commercial locations. The results of a ground survey. This article presents a survey and an outlook on commercial location in three differents sectors whereby the results are particularly interesting: spatial organization of equipments, dynamism of evolutions and motivations of differents locations. In every case, we have tried to demonstrate the methods to use and the primary possible methods that can be investigated. All methodolo¬gical problems are not yet resolved, but we can observe how the development of marketing geography of retailing depends on collecting technics and the modality of methods. [less ▲]

Our study tries by immunofluorescence to specify the nature of the connective tissue of the breasts, and especially of the scaffolding of the fatty tissue and the matrix of the lobules and of the lactiferous ducts. In consists of a study of 35 samples which were taken from 13 women whose ages ranged from 40 to 75 and whose breasts were considered on clinical examination and on radiography as normal or abnormal. We have analyzed the distribution of anti-collagen types I, III, IV and V and anti-fibronectin and anti-laminin antibodies in certain sites in the breast which were chosen because of the diversity of forms they could take from one woman to another. In each case of the distribution of protein markers seemed to be regular without, as can be found in certain cases of scar or tumour formation, a change in the distribution of the matrix proteins. Therefore, as already suggested by certain histologists, benign abnormal breast conditions (fibrosis) should be considered as simple variations from the normal. This conclusion agrees with classical histological findings. [less ▲]

Basement membrane components and collagen biosynthesis were studied in suction blisters in human skin. The basement membrane components were characterized by immunofluorescence using specific antibodies to type IV collagen, laminin and fibronectin, and collagen biosynthesis was studied by assaying galactosylhydroxylysyl glucosylatransferase. In suction blisters, the separation of epidermis and dermis occurred above the lamina lucida, indicating that the basement membrane, composed of lamina lucida and lamina densa, forms a mechanically strong entity. During the regeneration phase of blisters, type Iv collagen and laminin were not observed in the old epidermal blister roof. This indicates that keratinocytes when separated from the underlying basement membrane or connective tissue do not synthesize laminin or type IV collagen. Galactosylhydroxylysyl glucosyltransferase activity could be demonstrated in blister fluid and was about the same as in serum when expressed on the basis of protein in fresh blisters. It increased by 2-3 fold during the repair of blisters, indicating that there was local production of this enzyme. Further studies revealed that pure epidermis contained galactosylyhdroxylysyl glucosyltransferase and hydroxyprolineand this suggests that epidermis may synthesize some collagen type which, according to these studies, is not type IV (basement memebrane) collagen.

A patient developed concomitantly chondritis of the two auricles, diffuse cutaneous vasculitis and actinic granulomas. Alterations in skin and cartilage were prominent in the elastic tissue. Anticollagen type II antibodies were absent from the serum and there was no deposit of immunoreactants in cartilages. In this form of relapsing polychondritis, the pathomechanism resembles that of diffuse actinic arteritis as proposed by O'Brien. It is concluded that relapsing polychondritis may represent a heterogeneous syndrome with regard to its pathogenesis. [less ▲]

The effect of retinoic acid on the synthesis and degradation of basement membrane components by endoderm cells derived from mouse embryonal carcinoma (EC) cells was studied in a serum-free, defined medium. By immunofluorescence these cells accumulate type IV collagen, laminin, and fibronectin after growth in media containing epidermal growth factor (EGF), fibroblast growth factor (FGF), insulin, transferrin, and Pedersen fetuin. Collagen accounted for 2 to 4% of the newly synthesized proteins, of which 90% were found in the culture media. This collagen was identified as Pro-type IV be gel electrophoresis and enzymatic susceptibility. The EC cells preferentially attached to type IV collagen in vitro and such attachment was mediated by laminin. Treatment of EC cells with retinoic acid caused an increased accumulation of collagen (10 to 15% of secreted proteins) and also stimulated the elaboration of latent protease which degraded laminin and type IV collagen. The laminin-degrading activity was plasminogen dependent. The type IV collagen-degrading activity was a metal protease which could be activated by trypsin or plasmin. It is likely that at least part of the laminin degrading activity is plasmin (mediated through plasminogen activator), since highly purified plasmin is shown to degrade native laminin. [less ▲]

A new enzyme immunoassay has been developed for the demonstration of antiglomerular basement membrane antibodies. Magnetically responsive polyacrylamide-agarose beads (Magnogel) activated with glutaraldehyde were used to bind sonicated insoluble rat glomerular basement membranes. Both the collagenous and the non-collagenous moieties were demonstrated to be fixed on the beads. Sera from brown Norway rats with anti-glomerular basement membrane antibodies induced by HgCl2 injections were incubated with the beads. After washing, the fixed rat IgG were revealed using alkaline phosphatase labelled Fab fragments from anti-rat IgG sheep, IgGs. Comparison with a radioimmunoassay showed that results were reliable. This enzyme immunoassay has several advantages which may render this assay of considerable clinical usefulness. [less ▲]

Laminin was demonstrated by immunoperoxidase and immunofluorescence staining in sections of normal human tissues fixed in formalin and routinely processed in paraffin. Exposure of the sections to a solution of pepsin (Burns et al. (1980) Histochemistry 67:73-78) revealed the antigenicity of this basement membrane glycoprotein. Sections from paraffin blocks stored for years at room temperature could be stained with this procedure. Normal human tissues, developing fetal tissues and tumors could be stained with this method. The staining patterns were similar to those seen in unfixed frozen sections. It thus appears that basement membrane components can be detected by immunohistological means from routinely processed histological samples, once the sections are pretreated with proteases. Staining for laminin could be used in embryonic studies and in histopathology to study the relation of cells to basement membranes and for the visualization of normal and abnormal vascularization.
