Tonsils, which exposed continually to antigens, are the important site for recurrent inflammation in the pediatric population. The purpose of this study was to investigate the presence of Epstein-Barr virus (EBV) in children’s tonsils, and to reveal the potential infection mechanism correlation with latent membrane protein 1 (LMP-1) encoded by EBV in human tonsil epithelial cell (HTEpiC). Polym...

OBJECTIVE To explore the feasibility and efficacy of Z-palatoplasty for the management of severe obstructive sleep apnea-hypopnea syndrome in patients with tonsils. STUDY DESIGN Case series and chart review. SETTING University hospital. METHODS Z-palatoplasty and coblation channeling of the tongue were performed in 36 patients with body mass index <40 kg/m(2) and size 1 or 2 tonsils. All ...

OBJECTIVE The purpose of this study was to evaluate the variation in tonsil size and prevalence of asymmetric tonsils in 4- to 17-year-old schoolchildren and the relationships between tonsillar hypertrophy and frequent tonsillitis, frequent fever, and sleep-related symptoms observed by parents. DESIGN Cross-sectional study. SETTING Six daycare centres, four primary schools, and four high sc...

Infection of calves with bovine herpesvirus 1 (BHV-1) results in transient immunosuppression that may lead to bacterium-induced pneumonia and, occasionally, death. Although sensory neurons in the trigeminal ganglia (TG) are the primary site of BHV-1 latency, viral genomes are detected in the tonsils of latently infected calves. Dexamethasone (DEX) consistently induces reactivation from latency,...

This is an artic.:le about the pharyngeal lymphoid tissue. so called waldyer's ring. I have tride to give a rather clear discription of Its functi<"m, especially pointing to Its role in protecting the body against the infections by promoting the antibodv production and lymphocite formation.  In the view of these functions a clear cut indi­cations and contraindications of adenotonsillectomy has...

Healthy pigs carrying pathogenic to human Yersinia enterocolitica strains are the main source of entry into slaughterhouse, where cross-contamination of carcasses can happen. The aim of this work was to determine Y. enterocolitica prevalence in slaughtered pigs, investigating the presence of carriers in relation to carcass contamination. A total of 132 pig samples (tonsils, mesenteric lymph nod...

The effect of vaccination with a killed whole-cell vaccine of extracellular factor-positive Streptococcus suis serotype 2 (S suis 2 EF(+)) combined with medication with amoxicillin on the presence of virulent S suis 2 EF(+) strains on the tonsils of sows and their offspring was evaluated. In two herds, 14 pregnant sows that carried these virulent strains, as detected by PCR in three consecutive...

Bacteriologic samples from 31 young men were cultured quantitatively for aerobes and anaerobes; these samples included 31 specimens of tonsils (16 infected and 15 healthy), 16 specimens from pericoronal pockets of lower third molars (11 infected and 5 symptom-free), and 6 postoperative specimens from lower-third-molar extraction sockets. Anaerobes were isolated more often from infected third mo...

The palatine tonsils are constantly exposed to ingested or inhaled antigens which, in turn, lead to a permanent activation of tonsillar immune cells, even in a basic physiological state. The aim of the present study was to investigate if the immunological activation of the human palatine tonsil is reflected by a high metabolic activity, as determined by in vivo measurement of protein synthesis....

This study reports the prevalence of culturepositive Salmonella in lymphoid tissues of swine presented for slaughter in two municipal abattoirs in Mexico. Fifty tonsils, and 110 mandibular, 90 mesenteric, and 115 subiliac lymph nodes (LNs), were recovered from 115 pork carcasses sampled across four days during a six-month period in a Merida harvest facility. Additionally, 10 mandibular LNs, 10 ...
