    Description / Table of Contents: Résumé Chez 106 cadavres de japonais adultes, nous avons mis en évidence, aussi bien macroscopiquement que microscopiquement, des vaisseaux lymphatiques péri-oesophagiens qui se drainaient dans le conduit thoracique. Macroscopiquement, le drainage lymphatique de l'oesophage dans le conduit thoracique existait chez 46 des 106 cadavres (43,4 %). 23 gros collecteurs ont été vus qui naissaient de l'oesophage thoracique et s'abouchaient directement dans le conduit thoracique chez 21 des 106 cadavres (19,8 %). Le plus souvent (15 des 23 gros collecteurs), ces lymphatiques reliaient l'oesophage au conduit thoracique au niveau des 1er-3ème ou des 6ème-8ème vertèbres thoraciques. D'après l'examen histologique de ces 23 gros collecteurs, 2 prenaient naissance à partir d'un fin plexus lymphatique de l'adventice de l'oesophage infiltré de cellules mononucléaires. Dans 11 cas sur 23, un lymphonoeud intermédiaire a été trouvé sur le conduit thoracique grâce à des “clearing methods”. Ces résultats suggèrent que la lymphe de l'oesophage se draine rapidement dans la circulation systémique par l'intermédiaire du conduit thoracique. Importantes en clinique dans le cancer de l'oesophage, les descriptions antérieures de lymphatiques extrapariétaux de l'oesophage ont été discutées à propos de ce drainage lymphatique direct de l'oesophage.
    Notes: Summary The lymphatic vessels from around the esophagus which drain into the thoracic duct were identified macroscopically and histologically in 106 cadavers. Direct lymphatic drainage to the duct was macroscopically demonstrated by 84 vessels in 46 cases (43.4%). In 23 cases (19.8%), large collecting vessels arose from the thoracic esophagus and opened directly imto the duct. In most of these cases (15/23) these lymphatic connections were found at the levels of the 1st–3rd or 6th–8th thoracic vertebrae. Histologic study revealed that two vessels originated from the fine lymphatic plexus in the esophageal adventita, which showed monocytic infiltration. In 11 of the 23 cases, an intercalated node was found along the thoracic duct. The results suggest that lymph drains rapidly into the systemic circulation via the thoracic duct. In view of the clinical applications in esophageal carcinoma, previous accounts of the extramural esophageal lymphatics concerned in direct drainage are discussed.

    Notes: Abstract  The mannose-binding lectin (MBL) and MBL-associated serine proteases (MASPs) play crucial roles in activation of the lectin pathway of the complement system. Mammals and Xenopus possess two distinct MASPs, MASP1 and MASP2, with different substrate specificity. Recently, a truncated form named MAp19 or sMAP, composed of N-terminal C1r/C1s/Uegf/bone morphogenetic protein (CUB)-1 and epidermal growth factor domains of MASP2, has been shown to be generated by alternative polyadenylation and splicing from the MASP2 gene. In the present study, we isolated cDNA encoding a novel MASP-related protein, designated MRP, from carp. MRP is distinct from MAp19/sMAP in containing two additional domains, CUB-2 and short concensus repeat (SCR)-1, followed by a unique C-terminal 21 amino acids, but resembles it by also lacking the serine protease domain, suggesting that carp MRP is a functional homologue of human MAp19/sMAP. Analyses of polymerase chain reaction (PCR)-amplified carp genomic DNA, from CUB-2 to SCR-2 of MASP, indicated that carp possess duplicated MASP genes, designated MASP-A and MASP-B, both of which contain an exon encoding the MRP-specific C-terminal stretch between the exons coding for SCR-1 and SCR-2 domains. Reverse transcription-PCR analysis showed that both MASP genes of carp produce the two MASP isoforms, MASP and MRP, through alternative polyadenylation and splicing. The conservation of MASP isoforms that lack the catalytic domain in both carp and human implies that they meet an essential requirement in the MBL-MASP complex of the lectin pathway.

    Notes: Abstract The gene coding for 3-methylaspartate ammonia-lyase (3-methylaspartase, MAL, EC 4.3.1.2) from Citrobacter amalonaticus strain YG-1002 (TPU 6323) was cloned onto plasmid pBluescript II KS(+), and the nucleotide sequence of the 1239-bp open reading frame (ORF), consisting of 413 codons, was identified as the mal gene coding for MAL. The predicted polypeptide has 62.5% identity with MAL from the obligate anaerobe, Clostridiumtetanomorphum NCIMB 11547. ORF1, which showed 58.6% and 58.8% identities with subunit E of the glutamate mutases of C. tetanomorphum and Clostridiumcochlearium respectively, was found in the upstream region of the mal gene. An expression plasmid pMALCA3 (5.4 kb), in which the mal gene was expressed under control of the lac promoter on the vector, was constructed. With feeding of 1 mM isopropyl β-d-thiogalactopyranoside, the amount of the enzyme in a cell-free extract of the transformant, E. coli JM109/pMALCA3, was elevated to 51 800 units/l culture, which is about 50-fold that of C. amalonaticus strain YG-1002. It was calculated that the enzyme comprised over 40% of the total extractable cellular proteins. The enzyme produced by the E. coli transformant was purified in a crystalline form and shown to be identical to that of the wild-type strain with respect to specific activity, molecular mass, subunit structure, enzymological properties, and N-terminal amino acid sequences.

    Notes: Abstract We treated a Japanese boy with moyamoya disease accompanied by synbrachydactylia, funnel chest, pes equinus and short stature. Angiograms showed the anomalous origin of the occipital artery in addition to the moyamoya vascular network at the base of the brain. A generalised mesenchymal anomaly was suggested in this case.

    Notes: Summary Plasma levels and the area under the plasma concentration-time curve (AUC) values of 6-mercaptopurine (6-MP) were determined in a balanced crossover study of oral (powder) and rectal (macrogol suppository) administration to 5 children with acute lymphoblastic leukaemia (ALL). The AUC (538.6 ng · h · ml−1) after the rectal dose of 30 mg/m2 was approximately 1.5-times of that (365.5 ng · h · ml−1) after the oral dose of 87.5 mg/m2. The coefficients of variation of interindividual variability of the AUCs were 21.5% and 32.3%, respectively. The relative bioavailability of the macrogol suppository compared to the powder was approximately 4.39. These findings indicate that rectal administration of 6-MP could avoid the first-pass effect of this drug in the alimentary canal and/or liver, resulting in a large AUC of 6-MP, and so could reduce interindividual variability in plasma 6-MP concentrations. Rectal administration of 6-MP may be more effective than empirical oral dosing for the treatment of children with ALL, especially for patients with nausea and/or vomiting.
