The steppe, typical of central Mongolia, is dominated by C3 plants adapted to the continental climate. The following two questions are addressed: (1) how do NEE and its components: gross ecosystem production (GEP) and total ecosystem respiration (Reco) vary seasonally? (2) how do NEE, GEP, and Reco respond to biotic and abiotic factors? The hourly minimal NEE and the hourly maximal Reco were −3.6 and 1.2 μmol m−2 s−1, respectively (negative values denoting net carbon uptake by the canopy from the atmosphere). Peak daily sums of NEE, GEP, and Reco were −2.3, 3.5, and 1.5 g C m−2 day−1, respectively. The annual sums of GEP, Reco, and NEE were 179, 138, and −41 g C m−2, respectively. The carbon removal by sheep was estimated to range between 10 and 82 g C m−2 yr−1 using four different approaches. Including these estimates in the overall carbon budget yielded net ecosystem productivity of −23 to +20 g C m−2 yr−1. Thus, within the remaining experimental uncertainty the carbon budget at this steppe site can be considered to be balanced. For the growing period (from April 23 to October 21, 2003), 26% and 53% of the variation in daily NEE and GEP, respectively, could be explained by the changes in leaf area index. Seasonality of GEP, Reco, and NEE was closely associated with precipitation, especially in the peak growing season when GEP and Reco were largest. Water stress was observed in late July to early August, which switched the steppe from a carbon sink to a carbon source. For the entire growing period, the light response curves of daytime NEE showed a rather low apparent quantum yield (α=−0.0047 μmol CO2 μmol−1 photons of photosynthetically active radiation). However, the α values varied with air temperature (Ta), vapor pressure deficit, and soil water content.Type of Medium: Electronic ResourceURL: -

Published 2002Staff ViewISSN: 1365-2222Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Background Correcting Th1/Th2 imbalance with administration of IL-12 before and during antigen challenge holds therapeutic promise in asthma. However, the effects of IL-12 on the established asthmatic responses have not fully been examined.Objective We investigated whether IL-12 administered after antigen challenge could diminish airway hyper-reactivity (AHR) and eosinophilia in mice actively sensitized to ovalbumin. We also have investigated the ability of administered IL-12 to induce IL-18 receptor (IL-18R) expression that may lead possible synergic action of IL-12 with endogenous IL-18.Methods C57BL/6 mice immunized to ovalbumin (OVA) by intraperitoneal (i.p.) injection, were challenged three times with an aerosol of OVA every second day for 8 days. Recombinant IL-12 (500 ng) was intravenously administered on a single occasion 1 h after the final challenge of mice. Mice were analysed for effects of IL-12 on AHR, inflammatory cell infiltration and cytokine levels in lung tissue as well as serum immunoglobulin (Ig) E levels. Immunohistochemistry for IL-18R was performed using rat monoclonal antibody specific for murine IL-18Rα (IL-1 receptor related protein; IL-1Rrp).Results An intravenous IL-12 administration diminished AHR, pulmonary eosinophilia and T lymphocyte infiltration, serum IgE, IL-4 and IL-13 in lung tissue. Expression of IL-18R was induced in the mononuclear cells in the lung of mice exposed to OVA. IL-12 administration enhanced the IL-18R expression compared with the control.Conclusion These data indicate that IL-12 can attenuate established antigen-induced AHR and inflammation. In this mechanism it would be interpreted as follows: IL-12 administration in OVA-challenged mice decreased IL-4 production and IgE production thereafter through direct effect on inhibiting the activation of established Th2 cells response and also combined effect with up-regulation of IL-18R expression by inflammatory cells in the lung.Type of Medium: Electronic ResourceURL: -

Published 2001Staff ViewISSN: 1365-2222Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: Background and objective Carbon monoxide (CO) is known to be present in measurable quantities in the exhalation of asthmatic patients. Corticosteroid treatment resulted in a decrease in exhaled CO levels in asthmatic patients, raising the possibility that an increase in exhaled CO concentration reflects inflammation of the asthmatic airway. Heme oxygenase-1 (HO-1) protein, also called HSP32, is the rate-limiting enzyme in the catabolism of heme to biliverdin, free iron and CO. However, it is unknown whether an expression of HO-1 within the lung tissue is related to allergic airway inflammation. We studied the expression of HO-1 in lung tissue and bronchoalveolar lavage cells in a mouse model of asthma.Methods Ovalbumin (OVA)-sensitized C57BL/6 mice were challenged with aerosolized OVA. HO-1 positive cells were identified by immunostaining in lung tissue and bronchoalveolar lavage fluid (BALF) after the challenge.Results HO-1 positive cell numbers increased in the subepithelium of the bronchi after OVA challenge. In cytospin preparations from BALF after OVA challenge, HO-1 was localized to alveolar macrophages. Inside the macrophages, HO-1 reactivity was expressed in the cytoplasm, and the perinuclear region in particular.Conclusion The expression of HO-1 is increased within the lung tissue in allergic airway inflammation. Measurement of HO-1 activity may be clinically useful in the management of asthma.Type of Medium: Electronic ResourceURL: -

ISSN: 1440-1797Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: We compared an antiproteinuric effect of a lipid-lowering agent probucol on two distinct types of experimental nephrosis in rats, i.e. mercuric–chloride (HgCl2)-induced autoimmune glomerulonephritis in Brown Norway (BN) rats and puromycin aminonucleoside (PA)-nephrosis in Wistar rats. The rats were fed either standard rat chow or chow containing 5% probucol. BN rats were treated with HgCl2 according to a standard protocol (HgCl2 1 mg/kg subcutaneously three times/week). Probucol treatment did not ameliorate proteinuria, renal histology or a strong linear staining for IgG and an intercellular adhesion molecule, ICAM-1, in glomeruli. Wistar rats were made nephrotic with an intraperitoneal injection of PA (100 mg/kg). In this model, in contrast to the BN rat model, no glomerular deposition of IgG or ICAM-1 was observed. Probucol treatment ameliorated proteinuria significantly. These findings suggest that the response to probucol differs in different experimental nephrosis models. As probucol only affects PA-nephrosis, in which ICAM-1 expression is negative, the ICAM-1 attenuation is not likely to be involved in the antiproteinuric effect of probucol.Type of Medium: Electronic ResourceURL: -

Published 2002Staff ViewISSN: 1365-2842Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: summary Mastication modulates the autonomic nervous activity of the digestive glands and the heart. The autonomic nervous balance is evaluated with spectral analysis of heart rate variability. In the present study, we investigated the effects of mastication of chewing gum base on heart rate variability to clarify the role of mastication in the sympatho-vagal balance for the regulation of the heart rate. Mastication of a chewing gum base stimulated the salivary secretion and shortened the R-R intervals in the electrocardiogram of healthy young subjects without swallowing of saliva at a fixed rate of respiration. Based on the analysis of heart rate variability, mastication increased the low-frequency band spectral power (LF), and decreased the high-frequency band spectral power (HF). The LF/HF was markedly increased by the mastication. Mastication enhances the sympathetic nervous activity and/or suppresses the parasympathetic nervous activity for the heart. Feeding behaviour with mastication might play a role in the modulation of the autonomic nervous activity.Type of Medium: Electronic ResourceURL: -

Published 2003Staff ViewISSN: 1365-2842Source: Blackwell Publishing Journal Backfiles 1879-2005Topics: MedicineNotes: summary Mastication and swallowing increase the heart rate, and posture change and respiration also modulate the heart rate. To clarify the role of mastication and swallowing in the modulation of the autonomic nervous activity, we investigated how they interact with modulation of the heart rate by changing body positions and respiration in young healthy subjects. R–R intervals of electrocardiogram at rest were significantly changed with different body positions, compared with supine and standing. A net shortening by mastication of a chewing gum base was similar in various postures. Respiration induced a periodic change in the R–R intervals, depending on the body postures, but mastication did not markedly change them in each posture. Dry swallowing at rest and spontaneous swallowing during the mastication in the sitting position induced a similar transient shortening and suppressed the respiration-induced changes after the swallowing. The net transient shortening by dry swallowing at rest was similar in the different postures. These results suggest that signals from mastication and swallowing are summated with those from body positions and respiration for shortening the R–R intervals and that signals from swallowing suppress the respiration-induced periodic changes.Type of Medium: Electronic ResourceURL: -
