The ureC gene sequence was detected by PCR in 5 (16.6%) specimens (3 tonsils and 2 adenoids), all of which were also positive by RUT, thus were considered H. pylori infected. Accordingly, PCR had a 100% sensitivity and specificity. Serology testing was positive for H. pylori IgG antibodies in 4/20 patients (20%), only two of them were found to have H. pylori infected adenotonsillar tissue.

Conclusions: Based on our findings it seems that adenotonsillar click here tissue may constitute an extra-gastric reservoir for H. pylori in symptomatic children with chronic

adenotonsillitis. RUT was found to be of less accuracy than PCR in H. pylori detection in an extra-gastric location, thus results of previous studies using this test alone for detection of oral H. pylori should be treated with caution. (C) 2011 Elsevier Ireland Ltd. All rights reserved.”
“Introduction: Assessment of respiratory safety is one of the most important requirements for new chemical entity (ICH Guideline S7A). The aim of the present study was to compare and validate respiratory safety pharmacology models in conscious rats, to find out the most appropriate method for detection

of drug-induced adverse effects on respiratory function in preclinical safety studies. Methods: Head out plethysmography and whole body plethysmography check details methods were used to monitor typical parameters of ventilatory function like respiratory rate (RR), tidal volume (TV), minute volume (MV) and mid expiratory

flow (EF50). The effects of respiratory stimulant theophylline (100 mg/kg) and respiratory depressant chlordiazepoxide (100 mg/kg) were evaluated in both models. Propranolol (60 mg/kg) was also used to compare head out and whole body plethysmography because of its bronchoconstrictor effects on airway function. Results: Theophylline caused a significant increase in TV, EF50 and MV in both whole body and head out plethysmography. In whole body plethysmography, theophylline AMN-107 mw significantly increased RR, but this increase was not observed in head out plethysmography. Chlordiazepoxide significantly decreased RR, TV, EF50 and MV in head out plethysmography, but it significantly reduced only TV in whole body plethysmography. A significant reduction in TV was observed with propranolol in both whole body and head out plethysmography. Discussion: We conclude that ventilatory function can be accurately assessed using head out plethysmography compared to whole body plethysmography. Our experimental results of EF50 from non-invasive methods suggest that reliable assessment of airway function demand additional invasive methods. (C) 2011 Elsevier Inc. All rights reserved.”
