  • Injury within the olfactory mucosa from inhaled NA was confined to the medial meatus, whereas systemic NA generated severe injury throughout the olfactory region. (aspetjournals.org)
  • The pattern of nasal injury from inhaled NA in this study is consistent with previous studies of nasal airflow simulation within the olfactory region. (aspetjournals.org)
  • Shows the cellular and vasculature jejunal mucosa structure of the intestine. (indexedvisuals.com)
  • Severe cellular injury occurred exclusively in the olfactory mucosa 24 h postinhalation exposure to 3.4 ppm NA for 4 h. (aspetjournals.org)
  • Rhinitis medicamentosa - topical decongestant nasal drops are notorious for causing rebound phenomenon. (wikipedia.org)
  • Endobronchial and nasal mucosa biopsies were obtained from 5 patients with clinically-stable, diagnosed asthma (ATS criteria). (bmj.com)
  • Increases in HLA-DR expression were also seen in the nasal mucosa biopsies from asthmatics although the increases over normal did not reach statistical significance. (bmj.com)
  • Toxic metabolites generated in the nasal passage could pass into the systemic circulation due to the rich vasculature and high perfusion rate of the nasal region ( Ding and Dahl, 2003 ). (aspetjournals.org)
  • Their excessive use causes rhinitis if treated by withdrawal of nasal drops, short course of systemic steroid therapy and in some cases, surgical reduction of turbinates, if they have become hypertrophied. (wikipedia.org)
  • Conclusion The main histological features of the nasal mucosa in choanal atresia could be reversed by surgery, making the patients regain their choanal patency, with their mucosae changing back to normal gradually with time. (arquivosdeorl.org.br)
  • The nasal cavities become rheumy and are filled with foul smelling crusts which are black or dark green and dry, making expiration painful and difficult. (wikipedia.org)
  • The local immune response occurring during Staphylococcus aureus nasal colonization remains ill-defined. (tcd.ie)
  • Studies have highlighted the importance of T-cell immunity in controlling S. aureus colonization of the nasal mucosa. (tcd.ie)
  • IL-22 is basally expressed within the nasal mucosa and is induced upon S. aureus colonization. (tcd.ie)
  • IL-22−/− mice demonstrate significantly elevated levels of S. aureus nasal colonization as compared with wild-type (WT) mice. (tcd.ie)
  • We conclude that IL-22 has an important role in controlling S. aureus nasal colonization through distinct mechanisms, with IL-22 mediating its effect exclusively by inducing AMP expression and controlling availability of staphylococcal ligands. (tcd.ie)
  • After discussion, primary embolization could be useful to reduce vascularization of nasal fossa. (elidee.com)
  • This prospective study collected periodically nasal cells from mucosa of 17 volunteers from two different undergraduate programs with different workloads of practical lessons in an anatomy laboratory, 30 and 90 hours per semester. (isciii.es)

  • Normal subjects had few, if any, eosinophils and EPX as well as the measured parameters in their nasal lavage fluids before and after antigen challenge. (nii.ac.jp)
  • These results suggest that aerosolization of soluble antigen formulations with CT may provide an alternative method of delivering nasal vaccines to sheep and other large animal species, and that further improvements in antigen penetration of nasal tissues may dramatically improve the strength of the immune response.

  • The mucous within the nasal mucosa not only serves to remove bacteria from the air entering the respiratory system, but it also humidifies, or adds moisture, to the air. (wisegeek.com)
  • I had never understood why this happens but it's apparently the reaction of nasal mucosa to bacteria. (wisegeek.com)
  • Using a nasal swab from volunteers, they were able to isolate coccoid-shaped bacteria that were present among other naturally-produced organisms. (wikipedia.org)
  • Generally, local measures such as limited use of nasal drops, topical steroids and limited surgery (cryosurgery) to turbinates are sufficient to relate the symptoms. (wikipedia.org)
