High Rates of Detection of Respiratory Viruses in Tonsillar Tissues from Children with Chronic Adenotonsillar Disease
Chronic tonsillar diseases are an important health problem, leading to large numbers of surgical procedures worldwide. Little is known about pathogenesis of these diseases. In order to investigate the role of respiratory viruses in chronic adenotonsillar diseases, we developed a cross-sectional study to determine the rates of viral detections of common respiratory viruses detected by TaqMan rea...
متن کاملHuman Bocavirus in Iranian children with acute gastroenteritis
Background: Human Bocavirus ( HBoV) infection is of worldwide distribution. There is increasing evidence that HBoV is pathogenic for the human gastroenteric tract. However, less data are available on the role of HBoV in gastroenteritis. The present study was aimed to determine the prevalence of HBoV in children with gastroenteritis. Methods : Real-time PCR TaqMan was used to screen 200 st...
متن کاملEvaluation of bocavirus colonization in children with asthma
Introduction: the rate of colonization of bocavirus (a newly recognized respiratory virus) was assessed in children with asthma and non-asthmatic condition due to the importance of bocavirus in preventing and exacerbating of childhood asthma. Materials and Methods: In this study, 142 samples of nasopharyngeal swabs were assessed (71 with asthma and 71 without asthma). Viral nucleic acid was ext...
متن کاملNasopharyngeal Tonsils (Adenoids) Contain Extrathymic Corticothymocytes
Adenoidal tissue (also known as nasopharyngeal tonsils) of 58% of humans in the pediatric age group contains immature T-lymphoid cells with the phenotype of thymocytes (TdT+, CD1abc+, cytoplasmic CD3+, coexpressing CD4 and CD8, lacking an Intraepithelial Lymphocyte-associated phenotype). The notable difference in comparison to palatine tonsils is the clustering in groups and sheets, comprising ...
متن کامل[Immunohistological study on immunocompetent cells in palatine tonsil and pharyngeal tonsil--the quantitative study by image analyzer].
Distribution of various immunocompetent cells, i.e., IgG-, IgM-, IgA-, IgD-, IgE-, CD4-, and CD8-positive cells in palatine tonsils (tonsils) and pharyngeal tonsils (adenoids) of same patients were investigated immunohistologically by using monoclonal antibodies. The proportion of Ig-positive cells and T cell subsets in both tonsils were quantitatively studied by the image analyzer (CUE-2, Olym...
