  • This study was designed to examine mucosal injury to the rat nasal passage from acute exposure to NA by inhalation. (aspetjournals.org)
  • mucus

  • Mucus is the carrier in which the tiny particles reach these receptors in the nasal membrane, which then communicate with the brain to tell us what we are smelling. (wisegeek.com)
  • This is why when we have a stuffy nose or other issues with our nasal membrane or mucus, we are not able to smell as well. (wisegeek.com)

  • We investigated if intranasal immunization with amoebic lysates plus cholera toxin modified the populations of T and B lymphocytes, macrophages and dendritic cells by flow cytometry from nose-associated lymphoid tissue (NALT), cervical lymph nodes (CN), nasal passages (NP) and spleen (SP).

  • For a number of species, including nonhuman primates, nasal tissue, especially olfactory mucosa, contains high concentrations of P450s. (aspetjournals.org)
  • Based on their content of GPR99 mRNA, GPR99 is expressed in human kidney, placenta, fetal brain, and tissues involved in allergic and hypersensitivity reactions such as the lung trachea, salivary glands, eosinophils, mast cells derived from umbilical cord blood, and nasal mucosa, particularly the vascular smooth muscle in the latter tissue. (wikipedia.org)
  • Through it they continue their migration to the brain and, finally, the nasal tissue in a bill. (wikipedia.org)
  • In their final localisation (the nasal tissue), they occur 13-14 DPI and laying eggs starts 15 DPI. (wikipedia.org)
  • airway
  • It has been shown that interactions between CCR4 and MDC/CCL22 and TARC/CCL17, as well as between CCR8 and I-309/CCL1, are critical for the recruitment of Th2 cells in the airway mucosa of allergic diseases in response to allergen stimulation. (nii.ac.jp)
  • human
  • Illustration of the human nasal passage with an enlarged section showing its histology. (sciencephoto.com)
  • The project describes histomorphologically and biochemically the healing process in human respiratory mucosa after sinus surgery and searches for modulating factors. (ugent.be)
  • Despite the fact that naphthalene (NA), a volatile, ubiquitous air pollutant, was recently identified as a probable human carcinogen, little is known about nasal cytotoxicity from inhaled NA. (aspetjournals.org)
  • pterygopalatine
  • The pterygopalatine ganglion (Meckel's ganglion, nasal ganglion or sphenopalatine ganglion) is a parasympathetic ganglion found in the pterygopalatine fossa. (wikipedia.org)
  • structures
  • Specific infections, such as syphilis, lupus, leprosy and rhinoscleroma, may cause destruction of the nasal structures leading to atrophic changes. (wikipedia.org)
  • vasculature
  • Shows the cellular and vasculature jejunal mucosa structure of the intestine. (indexedvisuals.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)
  • passage
  • Nasal mucosa is considerably more lenient in letting molecules through than the blood-brain barrier, and so can act as a secret passage for drug delivery. (medgadget.com)
  • As a first entry point of inhaled compounds, the nasal passage is at risk of being injured by a number of air pollutants, such as naphthalene (NA). (aspetjournals.org)
  • systemic
  • 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)
  • sprays
  • Some of these commercials showed men, women, and children using other brands of nasal sprays, and then standing upside down or hanging upside down from playground equipment to prevent their nasal spray from dripping out. (wikipedia.org)
  • medial

  • fluids
  • 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)
  • Increased levels of SLPI in nasal secretions and bronchoalveolar fluids may be denotive of inflammatory lung conditions or allergic reactions, and increased levels of SLPI in plasma may be indicative of pneumonia. (wikipedia.org)
  • expression
  • In humans, significant expression/activity of P450s in the nasal mucosa have been reported. (aspetjournals.org)
  • 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)
  • patients
  • Endobronchial and nasal mucosa biopsies were obtained from 5 patients with clinically-stable, diagnosed asthma (ATS criteria). (bmj.com)
  • Patients reported symptom reductions were also collected to 6 months using the Sino-Nasal Outcome Test-22 Questionnaire and Rhinosinusitis Disability Index. (wikipedia.org)
