37. Distribution kinetics of enoxacin and its metabolite oxoenoxacin in excretory fluids of healthy volunteers.
The distribution kinetics of enoxacin and its main metabolite oxoenoxacin in excretory fluids was investigated in 11 healthy volunteers. A single intravenous dose of 428 mg of enoxacin was given as a 1-h infusion. Serial samples of plasma, urine, saliva, nasal secretions, tears, and sweat were drawn and analyzed for enoxacin and oxoenoxacin by reversed-phase

38. Feline Immunoglobulins
Immunoglobulins (Ig) in feline sera and secretions were identified by immuno-electrophoresis and immunodiffusion with rabbit antisera prepared to feline IgG, IgA, IgM, and whole serum. Adult cat sera, colostral whey, postcolostral sera, tears, and nasal secretions contained IgG, IgA, and IgM. IgG was the only Ig identified in precolostral sera and cerebrospi

39. Sudden blindness in a child: presenting symptom of a sphenoid sinus mucocele.
A 10-year-old girl with no nasal or respiratory symptoms developed a headache lasting a few hours. The next day she became totally blind in the right eye and over 5 days vision in the left eye deteriorated to bare light perception. The diagnosis of a sphenoid sinus mucocele was made radiologically and drainage via an endonasal sphenoidectomy produced 12 ml o

40. Staphylococcus aureus colonization and infection in patients on continuous ambulatory peritoneal dialysis.
Staphylococcus aureus is the most common cause of peritonitis in patients undergoing peritoneal dialysis in Brazil. Using restriction endonuclease analysis of plasmid DNA, we investigated the importance of chronic carriage of S. aureus in the development of peritonitis in patients on continuous ambulatory peritoneal dialysis at the Division of Nephrology, Es

41. Environmental survival of Haemophilus somnus and influence of secretions and excretions.
Environmental survival of the Haemophilus somnus virulent strain 43826 was examined by mixing it with bovine secretions and excretions and observing viability after storage at -70 degrees C, 3 degrees C, 23.5 degrees C and 37 degrees C at one day, five days, 12 days, 19 days and intermittently up to 75 days. Survival of the organism beyond 70 days occurred w

42. Fertility in men with primary ciliary dyskinesia presenting with respiratory infection.
BACKGROUND--Primary ciliary dyskinesia is characterised by chronic rhinosinusitis, chronic bronchial sepsis (usually with bronchiectasis), dextrocardia in approximately 50% of cases, and male infertility. The latter, described in patients attending infertility clinics, results from immotile but viable spermatozoa. Experience in a respiratory clinic suggests

43. Vitamin C controls the cystic fibrosis transmembrane conductance regulator chloride channel
Vitamin C (l-ascorbate) is present in the respiratory lining fluid of human lungs, and local deficits occur during oxidative stress. Here we report a unique function of vitamin C on the cystic fibrosis (CF) transmembrane conductance regulator (CFTR), a cAMP-dependent Cl channel that regulates epithelial surface fluid secretion. Vitamin C (100 μM) induced th

44. Influence of Host Factors on Immunoglobulin G Concentration in Oral Fluid Specimens
The influence of host factors (tobacco use, dentition, bleeding gums, oral rinsing, nasal medications, and time since the last meal) on immunoglobulin G (IgG) concentration in oral fluids (OF) was determined by univariate and multivariate analysis. Significant differences in IgG concentration were found to be associated with human immunodeficiency virus (HIV

45. Specific Immune Responses and Enhancement of Murine Pulmonary Clearance of Moraxella catarrhalis by Intranasal Immunization with a Detoxified Lipooligosaccharide Conjugate Vaccine
Moraxella catarrhalis is an important human mucosal pathogen. This study investigated the effect of intranasal immunization with a detoxified-lipooligosaccharide-cross-reactive mutant of diphtheria toxin (dLOS-CRM) vaccine candidate on pulmonary clearance following an aerosol challenge of mice with M. catarrhalis. Intranasal immunization with dLOS-CRM plus c

46. Synergistic proinflammatory responses induced by polymicrobial colonization of epithelial surfaces
The epithelial surfaces of the upper respiratory tract are continuously exposed to a wide variety of commensal microorganisms. In addition to acting as a physical barrier, epithelial cells respond to specific microbial products with the generation of signals, such as cytokines, that trigger inflammation. Because they are common components of the nasopharynge

47. Expression of C-Reactive Protein in the Human Respiratory Tract
C-reactive protein (CRP) is a normal constituent of human sera synthesized by hepatocytes and induced by proinflammatory cytokines. The function of this acute-phase reactant includes activation of complement and enhancement of opsonophagocytosis. CRP binds to phosphorylcholine (ChoP), a constituent of eukaryotic membranes that is also found on the cell surfa

48. Arachnoid clearance of red blood cells
Labelled red blood cells were instilled intraventricularly in groups of dogs and monkeys for evaluation of transfer to the vascular compartment. Blood levels were minimal (5% of the original material) with low-pressure infusions. A large movement (above 25%) of the type originally described by Simmonds occurred with high-pressure intraventricular infusions,
