13. Innate Antimicrobial Activity of Nasal Secretions
Minimally manipulated nasal secretions, an accessible form of airway surface fluid, were tested against indigenous and added bacteria by using CFU assays. Antimicrobial activity was found to vary between donors and with different target bacteria and was markedly diminished by dilution of the airway secretions. Donor-to-donor differences in electrophoresis pa

14. Determinants of Staphylococcus aureus Nasal Carriage
Nasal carriage of Staphylococcus aureus has been identified as a risk factor for community-acquired and nosocomial infections. We screened 230 donors of diverse ethnic and socioeconomic backgrounds and identified 62 (27%) whose nasal secretions were colonized by S. aureus. In 18 donors in whom the various regions of the nasal luminal surface were separately

15. Antibody Responses in the Lower Respiratory Tract and Male Urogenital Tract in Humans after Nasal and Oral Vaccination with Cholera Toxin B Subunit
Nasal vaccine delivery is superior to oral delivery in inducing specific immunoglobulin A (IgA) and IgG antibody responses in the upper respiratory tract. Although an antibody response in the nasal passages is important in protecting against primary colonization with lung pathogens, antibodies in the lungs are usually required as well. We immunized 15 male v

16. Nasal endotracheal intubation in a premature infant with a nasal encephalocele.
After a difficult nasal intubation a premature infant leaked cerebrospinal fluid (CSF) from one nostril. After developing bacterial meningitis, the baby was referred for neurosurgical management of the CSF fistula. Transaxial computed tomograms demonstrated a nasal encephalocele, but coronal scans were needed to show the defect in the cribriform plate.

17. Nitric oxide metabolites in nasal lavage fluid of patients with house dust mite allergy.
BACKGROUND--The role of nitric oxide in the early and late phase of the allergic process was investigated in patients with allergic rhinitis against house dust mite and the effect of fluticasone propionate aqueous nasal spray was determined. METHODS--Production of nitric oxide (measured as nitrite+nitrate) in vivo in nasal mucosa was examined in 24 patients

18. Effects of topical capsaicin in seasonal allergic rhinitis.
BACKGROUND--Mucosal exudation (luminal entry) of bulk plasma is a key feature of airway defence and inflammation. In guinea pig and rat airways this response is readily produced by neurogenic irritants, notably capsaicin. Thus "neurogenic airway inflammation" has become an established concept. The present study examines whether capsaicin also produces mucosa

19. Bordetella bronchiseptica Persists in the Nasal Cavities of Mice and Triggers Early Delivery of Dendritic Cells in the Lymph Nodes Draining the Lower and Upper Respiratory Tract
Early after the intranasal instillation of Bordetella bronchiseptica into mice, not only are mature dendritic leukocytes recovered from lung parenchyma and bronchoalveolar lavage fluid but their numbers are also increased in the mediastinal lymph nodes and the nasal mucosa-associated lymphoid tissue. Later during the infectious process, the bacteria persist

20. Sympathetic and parasympathetic interaction in vascular and secretory control of the nasal mucosa in anaesthetized dogs.
1. In dogs anaesthetized with pentobarbitone, electrical stimulation of the parasympathetic nerve fibres to the nasal mucosa evoked frequency dependent increases in both nasal arterial blood flow and nasal secretion. Blood flow was measured using a transonic flow probe placed around the artery. 2. Sympathetic nerve stimulation for 3 min at 10 Hz evoked signi

22. Inadvertent brain penetration during neonatal nasotracheal intubation.
During routine nasal intubation of a premature infant, the endotracheal tube penetrated the brain. Bloodstained cerebrospinal fluid and neural tissue was apparent. Initial cranial sonography was normal, but the infant later developed extensive intracranial haemorrhage. Rotation of an endotracheal tube to facilitate insertion angles the bevel at the tip upwar

23. The lateral nasal gland of dog: its structure and secretory content.
Lateral nasal glands of 12-15 weeks old pups are immature. Gland acini of pups and mature dogs contain numerous electron-lucent vacuoles with basophilic, electron-dense cores. The vacuoles contain both acid and neutral glycoproteins, sialated glycoproteins being the dominant acidic moiety. Lateral and basal cytoplasmic extensions of the acinar cytoplasm grea

24. Reversibility and reproducibility of histamine induced plasma leakage in nasal airways.
Plasma exudation is one cardinal factor in airways defence and inflammation. In inflammatory airway diseases such as rhinitis and asthma, however, plasma leakage may also have a pathogenetic role. Experimental data from animals indicate that highly sensitive, active, and reversible processes regulate the vascular and mucosal permeability to macromolecules. W
