Lotus japonicus contains two distinct ENOD40 genes that are expressed in symbiotic, nonsymbiotic, and embryonic tissues.

ENOD40, an early nodulin gene, has been postulated to play a significant role in legume root nodule ontogenesis. We have isolated two distinct ENOD40 genes from Lotus japonicus. The transcribed regions of the two ENOD40 genes share 65% homology, while the two promoters showed no significant homology. Both transcripts encode a putative dodecapeptide similar to that identified in other legumes forming determinate nodules. Both ENOD40 genes are coordinately expressed following inoculation of roots with Mesorhizobium loti or treatment with purified Nod factors. In the former case, mRNA accumulation could be detected up to 10 days following inoculation while in the latter case the accumulation was transient. High levels of both ENOD40 gene transcripts were found in nonsymbiotic tissues such as stems, fully developed flowers, green seed pods, and hypocotyls. A relatively lower level of both transcripts was observed in leaves, roots, and cotyledons. In situ hybridization studies revealed that, in mature nodules, transcripts of both ENOD40 genes accumulate in the nodule vascular system; additionally, in young seed pods strong signal is observed in the ovule, particularly in the phloem and epithelium, as well as in globular stage embryos.

[Percutaneous catheterization of the deep brachial vein].

50 attempts of deep percutaneous antecubital catheterization are reported. A tourniquet was applied to the upper arm and the medial deep brachial vein was punctured in a point immediately medial to the brachial artery, in the antecubital fossa. Venepuncture was successful in 88% of the cases (44 cases), catheterization possible in 72% of the cases (36 cases). The catheter reached the central venous compartment in 60% of the cases (30 cases). The only benign complication was injury to the brachial artery in 6 cases. Mean duration of catheterization was 20 days. This very easy and safe technique can be used when superficial veins are unusable and use of the deep central veins dangerous or impossible.

[Anorectal tuberculosis disclosed by hemorrhoidal thrombosis].

The authors report on a case of anorectal tuberculosis. Revealed by an hemorroïdal thrombosis with febrile symptoma and purulent discharge, its macroscopic aspect was the one of anal mucous membrane ulceration, irregular with elevated border. The diagnosis was confirmed by anatomopathologic exam. The course was favourable under specific treatment. Etiologic investigation did not show any other localisation. Then, present aspects of anorectal tuberculosis are discussed, as well as possible relationships with hemorroïdal disease and its complications, particularly the fissural ones.

[Thrombosis of the superior vena cava in Behcet's disease. Apropos of a case associated with chylothorax].

The authors report a case of superior vena cava thrombosis associated to a chylothorax during Behcet's disease. This thrombosis was revealed during an evolutive phase by dyspnea and a superior vena cava syndrome. Its course was favourable under a medical treatment associating: pleural drainage, parenteral feeding, corticotherapy and heparin therapy. Then the authors review the bibliography and recall the frequency, pathogenesis, clinic and treatment of this unusual complication of the Touraine's aphthosis. Such a complication appears paradoxically to present a favourable course.
