    Notes: The economic impact and medical complication rate of the common cold are well documented, but many of the physiological, inflammatory, and immune responses to common cold viruses have only recently been investigated. The purpose of this study was to compare selected systemic immune and inflammatory responses to experimental rhinovirus (RV)-39 challenge in seronegative allergic rhinitis and non-allergic rhinitis subjects. Peripheral blood was obtained before (baseline), during (acute), and 23 days after (convalescent) RV-39 intranasal challenge and assayed for leucocyte histamine release, serum immunoglobulins, allergen-specific IgE antibodies, plasma histamine. and platelet aggregation. All subjects were infected, as manifested by viral shedding in nasal secretions or seroconversion. RV-39 infection induced significant acute increases in serum IgE. leucocyte histamine release, and platelet aggregation, but caused no changes in serum IgG, serum IgA, serum IgM, and plasma histamine. The first change was confined to the allergic rhinitis subjects. There was no evidence that the acute rise in total serum IgE was due to an elevation of a pre-existing, pollen-specific serum IgE antibody. The results show that intranasal challenge with RV-39 induced changes in systemic immune and inflammatory parameters with a unique response pattern in allergic rhinitis subjects.

    Gastrojejunal interposition for esophageal replacement (1999)

    Notes: Abstract The main considerations in replacing the esophagus are to avoid postoperative necrosis of all or part of the graft, leakage or stenosis of the anastomoses, and complications related to acid-peptic or alkaline reflux. A 5-year-old boy, after two unsuccessful thoracic operations for atresia and then stenosis of the esophagus, underwent resection of the esophagus because of duodeno-gastroesophageal reflux. The continuity of the alimentary tract was restored by gastrojejunal interposition. We recommend this method of reconstruction when the esophago-gastrostoma is created in the chest, and the possibility of alkaline reflux must be considered.

    Involvement of glibenclamide-sensitive potassium channels in vasorelaxation by cochlear nerve stimulation (1997)

    Notes: Abstract Rabbit aortic rings relaxed with an increase in cyclic guanosine monophosphate and cyclic adenosine monophosphate content in response to exposure to organ fluid of isolated cochleas of the guinea pig following field stimulation (50 Hz, 80 V, 0.2 ms). Relaxations were blocked by 30 μMN G-nitro-l-arginine methyl ester added to the vessel rings. This inhibitory effect was reversed by 3 MMl-arginine. Removal of the vascular endothelium also blocked the relaxation response. Glibenclamide attenuated vasorelaxation in a concentration-dependent manner. We conclude that cochlear nerve stimulation induces an endothelium-dependent vasorelaxation involving activation of adenosine triphosphate-sensitive potassium channels.

    Description / Table of Contents: Résumé. Nous avons examiné le déplacement antéropostérieur de la tête humérale dans l’articulation glénohumérale en utilisant l’Imagerie par Résonance Magnétique (IRM). Nous avons étudiés 10 épaules normales, 11 épaules avec une instabilité antéropostérieure, 10 épaules stabilisées par la procédure de Putti-Platt et une épaule avec une instabilité multidirectionnelle. Nous avons mis le bras en 3 positions différentes: en rotation interne, en rotation externe et en abduction complète. Nous avons utilisé l’imagerie par echo de gradient. 22 épaules se prêtaient bien à l’évaluation. Nous avons obtenu des résultats constants dans les épaules normales. Les épaules instables et stabilisées montraient une plus grande variance. En rotation externe, nous n’avons pas trouvé un déplacement significatif dans aucune groupe. Cependant, la rotation externe était significativement réduite dans les épaules instables et les épaules stabilisées (P 〈0.01). Nous avons trouvé une tendance à un déplacement postérieure quand le bras était mis en rotation interne, avec une moyenne de 1 (±ku0.44) mm dans les épaules normales, 0.89 (±ku1.67) mm dans les épaules instables et 1.6 (±ku1.4) mm dans les épaules stabilisées.
    Notes: Summary. Anteroposterior translation of the humeral head within the glenohumeral joint was investigated using MRI. Ten normal shoulders, 11 recurrent anterior dislocations, 10 stabilised shoulders after the Putti-Platt operation and one shoulder with multidirectional instability, were scanned. The arm was positioned in internal and external rotation and in an overhead position. Gradient echo volume acquisition scans were carried out, and 22 were suitable for evaluation. Consistent results were obtained in the normal shoulders. The unstable and unstable shoulders showed higher variance, but there was no significant anterior translation in external rotation in any group. The range of external rotation was significantly reduced in the unstable and stabilised shoulders. A trend towards posterior translation was found in internal rotation with a mean of 1 (±ku 0.44) in normal, 0.89 (±ku1.67) in unstable and 1.6 (±ku1.4) in stabilised shoulders.

    Cryopreservation of horse-chestnut (Aesculus hippocastanum L. ) somatic embryos using three different freezing methods (1998)

    Notes: Abstract Cryopreservation of somatic embryos of Aesculus hippocastanum L. cultured on nutritive media containing abscisic acid (ABA) at concentrations of 0.75 μM, 7.5 μM and 75.0 μM was evaluated for three cooling methods: (i) slow freezing with cryoprotectants, (ii) fast freezing with cryoprotectants, and (iii) fast freezing with desiccation techniques. The ‘cryoprotectant’ freezing techniques included the embryo pretreatment on ABA containing medium for 4 days, followed by cryoprotective treatment in liquid medium containing 0.5 M dimethylsulfoxide, 0.5 M glycerol, 1.0 M sucrose, and cooled at slow, and rapid rates. Embryos pretreated on a medium containing 0.75 μM ABA, and cooled to −35 °C at 1°C /min, held for 30 min at this transfer temperature and then immersed in liquid nitrogen (LN) had the best embryo recovery (43%). The ‘desiccation’ method involved an air drying step of similar ABA-pretreated, non-cryoprotected embryos followed by rapid cooling. Embryos precultured on 0.75 μM ABA, then subjected to a 4 h period of air desiccation (water content reduction to 13%) showed about the same level of survival (46%) as found with the ‘cryoprotectant’ slow freezing technique. The air-dry ‘desiccation’ method is easier to apply than the more complicated ‘cryoprotectant’ method.
