    Induction, distribution and modulation of upper airway allergic inflammation in mice (2001)

    Notes: Background To further elucidate mechanisms of human allergic rhinosinusitis, we studied the induction, distribution and modulation of allergen-induced upper airway inflammation in a BALB/c mouse model.Methods Allergic inflammation induced with ovalbumin (OVA) by intraperitoneal (IP) injection in alum was compared to repeated intranasal instillation. The type and distribution of inflammatory cells was compared in the respiratory and olfactory epithelial compartments. Eosinophil distribution was assessed using Scarlet Red stain and a polyclonal antibody recognizing eosinophil major basic protein (MBP). The role of interleukin (IL)-5 in upper airway inflammation was tested by administration of polyclonal anti-IL-5 antibody during the sensitization protocol.Results Unsensitized control mice receiving saline failed to develop upper airway eosinophil infiltration. IP OVA-sensitized mice developed marked upper airway mucosal eosinophil infiltration after aerosol OVA challenge, whereas repeated intranasal instillation of OVA produced qualitatively similar, but less intense eosinophil infiltration. Using either sensitization protocol, eosinophil infiltration was seen in areas of the lower portion of the nasal septum, the floor and the lower lateral walls of the mid-caudal region of the nasal cavity. Immunofluorescence staining for MBP confirmed this distribution of eosinophils but also demonstrated some eosinophils in the maxillary sinuses and in circumscribed regions of the ethmoturbinates. All areas of eosinophil infiltration were lined by respiratory epithelium. The selective infiltration of respiratory but not olfactory epithelium by eosinophils was unassociated with a measurable induction of epithelial ICAM-1 or eotaxin expression. OVA-induced upper airway eosinophil infiltration was found to be IL-5 dependent, since administration of a polyclonal anti-IL-5 antibody (TRFK-5) during OVA sensitization resulted in a marked modulation (80% decrease) in eosinophil infiltration in response to subsequent OVA challenge.Conclusion The mouse upper airway, specifically in areas containing respiratory epithelium, is a target for OVA-induced allergic inflammation. This selective infiltration of respiratory, but not olfactory, epithelium is, in part, dependent upon IL-5. This model is useful for further dissection of the inflammatory response with genetic manipulations and targeted immunological approaches.

    Production of inulo-oligosaccharides from inulin by recombinant E. coli containing endoinulinase activity (1999)

    Notes: Abstract To utilize intracellular endoinulinase for inulo-oligosaccharide (IOS) production from inulin, the endoinulinase gene (inu1) of Pseudomonas sp. was successfully cloned into the plasmid pBR322 by using EcoRI restriction endoinulinase and E. coli HB101 as a host strain. The endoinulinase from E. coli HB101/pKMG50 was constitutively expressed, showing similar reaction modes as compared to those of the original strain. However, some critical differences existed in optimal reaction conditions and oligosaccharide compositions between the two products catalyzed by the native enzyme of original strain and those by intact cells from recombinant cells. The IOS compositions produced by recombinant E. coli were quite different due to the diffusional restriction of the substrate and products within the cell wall. Optimal reaction conditions for batchwise production of IOS were as follow : optimum temperature, 55 °C; pH, 7.5; substrate concentration, 100 g/l inulin; enzyme dosage, 20 units/g substrate. Continuous production of IOS from inulin was also carried out at 50 °C using a bioreactor packed with the recombinant cells immobilized on calcium alginate gel. The optimal feed concentration and the feed flow rate were 100 g/l inulin and 0.6 h−1 as a superficial space velocity, respectively. Under the optimum operation conditions, continuous production of IOS was successfully performed with productivity of 166.7 g/l·h for 15 days at 50 °C without significant loss of initial activity.

    Continuous production of inulo-oligosaccharides from chicory juice by immobilized endoinulinase (2000)

    Notes: Abstract Several carrier materials were examined for endoinulinase immobilization. A polystyrene carrier material (UF93®) gave the best immobilization capacity (217 units/g carrier) and operational stability. Carbohydrate compositions in the reaction product were quite similar irrespective of the support materials even though each carrier material has different pore structure associated with diffusional restriction. After immobilization the optimal pH for enzyme activity was shifted from 5.0 to 4.5, whereas optimal temperature (55 °C) was unaltered. Continuous production of inulo-oligosaccharides from chicory juice was carried out using the polystyrene-bound endoinulinase. The recommended operating conditions of the enzyme reactor for maximizing productivity were as follows: feed concentration, 100 g/l chicory juice; flow rate, as superficial space velocity 2.0 h−1; temperature, 55 °C. The enzyme reactor was run for 28 days at 55 °C achieving an oligosaccharide yield of 82% without any significant loss of initial enzyme activity, where the volumetric productivity was 200 g/l · h. Furthermore, there was no marked difference in operational stability between the two reactors fed with pure inulin solution and with chicory juice as a substrate even though chicory juice contains a lot of impurities.

    Effect of intramolecular and intermolecular exchange processes on the 1H NMR spectra of 2-chloro-1,3,2-dioxarsolanes (1987)

    Notes: The 1H and 13C NMR spectra of solutions of 2-chloro-4,4,5,5-tetramethyl-1,3,2-dioxarsolane (1) and 2-chloro-1,3,2-dioxarsolane (2) are reported as a function of temperature, concentration and solvent. These data indicate rapid intramolecular conformational averaging for (1) and (2) under all the conditions investigated. Additionally, intermolecular conformational averaging processes are shown to be present. The kinetic parameters for intermolecular exchange were obtained from line shape analysis of the 1H NMR data. These results indicate the intermolecular exchange to be bimolecular in nature, involving a four-centered transition state. The O—CH2—CH2-O torsional angle of (2) has been calculated from the analysis of its AA′BB′ 1H NMR spectral patterns, obtained at low concentrations in the absence of intermolecular exchange.
