Fexofenadine modulates T-cell function,preventing allergen-induced airway inflammation and hyperresponsiveness 总被引:3,自引:0,他引:3

BACKGROUND: Antihistamines have been evaluated for usefulness in the treatment of asthma for more than 50 years. Interest was limited until the introduction of newer compounds that were free of much of the dose-limiting sedation associated with the earlier drugs. OBJECTIVE: In a murine model of allergen-induced airway inflammation and hyperresponsiveness, the efficacy of an H1 receptor antagonist to prevent allergic inflammation and altered airway function was evaluated. METHODS: Mice were sensitized and challenged to an allergen, ovalbumin, which elicited marked airway and tissue eosino-philia and airway hyperresponsiveness. Fexofenadine was administered before challenge, and airway responsiveness to inhaled methacholine, airway and tissue eosinophilia, bronchoalveolar lavage fluid cytokine levels, and serum IgE levels were assayed. In a second group of experiments, sensitized and challenged mice were treated or not treated with fexofenadine before challenge. T cells were isolated from the lungs and adoptively transferred into naive recipients before exposure to limited airway allergen challenge, and lung function and inflammation were evaluated. RESULTS: Fexofenadine treatment of sensitized mice prevented the development of airway hyperresponsiveness in both the primary sensitization and challenge, as well as in the adoptive transfer experiments. These changes were accompanied by decreases in bronchoalveolar lavage and tissue eosinophilia, lymphocyte numbers, and T(H)2 cytokine production. CONCLUSION: The results demonstrate the efficacy of an H1 receptor antagonist in preventing allergen-induced alterations in pulmonary inflammation and airway function. The data support the evaluation of drugs such as fexofenadine in the treatment of allergic asthma. 相似文献

Strictureplasty for short duodenal stenosis in Crohn's disease 总被引:2,自引:0,他引:2
Takesue Y Yokoyama T Akagi S Ohge H Murakami Y Imamura Y Uemura K Kanehiro T Matsuura Y 《Journal of gastroenterology》2000,35(12):929-932
Involvement of the gastroduodenum is extremely rare in Crohn's disease. For obstructing duodenal Crohn's disease, bypass
procedures have traditionally been selected. However, more recently, strictureplasty has become an acceptable surgical option.
We treated two Crohn's disease patients with short proximal duodenal stenosis, using Finney-type strictureplasty. Their postoperative
courses were uneventful and they have remained asymptomatic during follow-up periods of more than 5 years, and 4 months, respectively.
Owing to the good clinical results of our two patients, we consider strictureplasty to be indicated for short proximal duodenal
stenosis in Crohn's disease.

AbstractTo clarify the topographical relationship between peri-Rolandic lesions and the central sulcus, we carried out presurgical functional mapping by using magnetoencephalography (MEG), functional magnetic resonance imaging (f-MRI), and motor evoked potentials (MEPs) on 5 patients. The sensory cortex was identified by somatosensory evoked magnetic fields using MEG (magnetic source imaging (MSI)). The motor area of the hand region was identified using f-MRI, during a hand squeezing task. In addition, transcranial magnetic stimulation localized the hand motor area on the scalp, which was mapped onto the MRI. In all cases, the sensory cortical vein or the lack of any functional activation in the area of peri-lesional edema. MEPs were also unable to localize the entire motor strip. Therefore, at present, MSI is considered to be the most reliable method to localize peri-Rolandic lesions.

PURPOSE: This study was performed to predict incontinence following low anterior resection for rectal cancer. METHODS: Preoperatively, 21 patients were evaluated
via
patient history and a physical examination that included anal manometric studies. Six months postoperatively, repeat manometric studies and clinical evaluations were performed to assess the level of continence. Degree of continence was graded based on severity of the dysfunction and grade of the continence score. RESULTS: The formula used for predicted postoperative resting pressure is as follows: predicted postoperative resting pressure=0.42 × preoperative resting pressure+1.56 × length of remaining rectum+12.37 (R
2
=0.58;P
<0.001). It was demonstrated that patients with low predicted postoperative resting pressures (<30 mmHg) had incontinence, and those with high predicted postoperative resting pressures (>35 mmHg) were continent. There were significant correlations between length of the remaining rectum and ratio of the decrease in maximum resting pressure (postoperative/preoperative maximum resting pressure;r
=0.63;P
<0.01). CONCLUSIONS: Continence following low anterior resection may be influenced by maximum resting pressure function of the internal anal sphincter; if it is injured during surgery, incontinence will occur. We may be able to foretell incontinence by using the predicted postoperative resting pressure formula, which is calculated by using preoperative resting pressure measurements and then determining the length of the remaining rectum.Abstract presented at the meeting of The Japanese Society of Gastroenterological Surgery, Tokyo, Japan, July 18 to 19, 1996. 相似文献

Regulation of airway hyperresponsiveness by calcitonin gene-related peptide in allergen sensitized and challenged mice 总被引:6,自引:0,他引:6

Sensory neuropeptides are localized to airway nerves and endocrine cells in both human and animal species and may participate in the development of airway inflammation and hyperresponsiveness (AHR). We used a mouse model to identify the changes that occur in calcitonin gene-related peptide (CGRP) expression in the airways during development of allergic inflammation and to investigate the potential role of this neuropeptide in modulating AHR. In sensitized mice, allergen challenge induced eosinophilic airway inflammation and AHR and resulted in considerable depletion of CGRP in neuroepithelial bodies and submucosal nerve plexuses without altering the overall density of airway nerve fibers. This depletion was subsequent to the development of airway inflammation and was prevented by anti-very late antigen-4 and anti-interleukin-5 treatments, which blocked airway eosinophilia and abolished AHR. Administration of CGRP to sensitized and challenged mice resulted in the normalization of airway responsiveness to inhaled methacholine, an effect that was neutralized by the receptor antagonist CGRP(8-37). These data demonstrate that replacement of CGRP following its depletion in allergic mice can reverse the changes in airway responsiveness and suggest that CGRP may have potential for the treatment of allergic AHR. 相似文献
