Duplicate determinations of pulmonary blood volume (Qp) were made in 16 supine resting normal subjects by use of arterial dye curves after pulmonary arterial and pulmonary wedge injections of indocyanine green. In five subjects Qp and pulmonary vascular resistances were unchanged during exercise.

Resume Vingt et un malades operes a cœur ouvert ont ete etudies en vue de rechercher chez eux l'apparition d'anticorps anti-HL-A post-transfusionnels. Le groupe HL-A de 18 de ces malades a ete effectue de meme que le groupe HL-A des donneurs de sang frais. Une seule personne s'est immunisee et il s'agit d'une femme. Une fausse-couche ayant eu lieu 22 ans avant l'intervention semble etre a l'origine de l'immunisation constatee.

Experimental determination of the distribution coefficients in diopside-liquid pairs for strontium and nine rare-earth elements in the system CaMgSi2O6-NaAlSi3O8-CaAl2Si2O8. In experiments in air at 1265 C it is found that most of the Sr(2+), Eu(2+), and RE(3+) ions substitute for Ca(2+) and, in addition, a coupled substitution of Al(3+) for Si(4+) occurs. All of the trace ions considered are found to be excluded from the diopside lattice relative to the liquid. In the case of the trivalent ions the exclusion is much more pronounced for La and Ce, which have ionic radii larger than that of Ca(2+) in 8-fold oxygen coordination. Divalent Sr and Eu with even larger radii are also strongly excluded.

In a statistical analysis of more than 2000 IgE estimations, the authors corroborate the importance of this determination for diagnosis of asthma, eczema and rhinitis. Serum IgE levels are also elevated in parasitic diseases, and may be elevated in some other cases in which there are several disorders, such as cirrhosis and leukemia.

The authors report their experience of treating certain forms of coxarthrosis by valgus osteotomy (Pauwel's operation II). Their study was carried out on 80 patients in whom the disease was of sufficient duration. The authors recall the main principles of biomechanics that must be strictly applied following careful and detailed study of the radiological films and of the results of the pre-operative test: failure to do this will lead to failure in treatment. The cases that are usually improved by the Pauwels II operation are those arthroses with a flattened head or with gout, often dislocated. The authors describe the surgical technique and the postoperative treatment. They obtained very good or good results in 85 percent of cases, and unsatisfactory results in 15 percent of patients, mainly because of errors at beginning of the series. As with varus, osteotomy, these operations must be regarded as surgery to relieve restrictions on movement and not surgery to restore shape.

The authors recall briefly the applications of Pauwel's theories concerning surgery in cases of gonarthrosis, which must be surgery to relieve restrictions on movement and not surgery to restore shape. They describe briefly the main biomechanical principles which must guide the pre-operative investigations and report their experience with a technique proposed by Blaimont and perfected by Maquet, the advantage of which is the exactness of the surgical correction. The technique is also useful in cases of femoro-patellar arthrosis. Among 120 osteotomies carried out using this method, the authors obtained very good or good results in 85 per cent of cases, and fairly good or poor results in 15 per cent of the patients. This method makes it possible to avoid in the great majority of cases recourse to total prostheses of the knee.
