Tonsil is rich in lymphatics, blood vessels, muscle, nearby nerve fibers and epithelium. All of these are potential sources of malignancy. Malignancy of the tonsils is an uncommon entity that accounts for little more than 0.5% of new malignancies in the United States every year. Approximately, more than 70% of malignancies in this region are squamous cell carcinoma. In this report, I introduce a case of 47 year male patient who has right tonsillar cancer that is squamous cell carcinoma(T4N3M0). After three times chemotherapy, the patient refused to get conventional western medical treatment including chemotherapy and surgical operation. After 8 month of traditional oriental medical treatment using allegen removed Rhus Verniciflua Stokes(ARV), the size of cancer mass decreased and mass showed necrosis at inner portion. The patient improved pain in the neck. More case will be needed in order to determine the effect of ARV on tonsillar cancer.

Basaloid squamous carcinoma (BSC) is an uncommon aggressive variant of squamous cell carcinoma with a predilection for hypopharynx, tongue base, and larynx. We present 5 cases of BSC of unusual sites, each from maxillary sinus, external auditory canal, submandibular gland, tonsil, and nasopharynx. Only a few cases arising in these sites have been reported to date. Patients included 3 men and 2 women with the age range of 45-69 years (mean, 56.4 years). Microscopically, the tumors were characterized by solid lobules and nests of ovoid basaloid cells with abundant desmoplastic stroma. Comedonecrosis, peripheral palisading of tumor cells, trabecular pattern, and rosette-like arrangement were commonly observed. Tumor cells had scanty cytoplasm and their nuclei were ovoid, relatively uniform, and hyperchromatic. In two cases, concomitant squamous cell carcinoma in situ was identified. Immunohistochemical stains revealed that tumor cells were strongly positive for pancytokeratin and negative or weakly positive for p63. Being aware of BSC that can arise from unusual sites would help diagnose correctly and treat properly this rare and distinct clinicopathologic entity.

Objective: This study assessed the effects of probiotics on cecal microbiota, gene expression of intestinal tight junction proteins, and immune response in the cecal tonsil of broiler chickens challenged with Salmonella enterica subsp. enterica. Methods: One-day-old broiler chickens (n = 240) were randomly allocated to four treatments: negative control (Cont), multi-strain probiotic-treated group (Pro), Salmonella-infected group (Sal), and multi-strain probiotic-treated and Salmonella-infected group (ProSal). All chickens except those in the Cont and Pro groups were gavaged with 1×10⁸ cfu/mL of S. enterica subsp. enterica 4 days after hatching. Results: Our results indicated that body weight, weight gain, and feed conversion ratio of birds were significantly reduced (p<0.05) by Salmonella challenge. Chickens challenged with Salmonella decreased cecal microbial diversity. Chickens in the Sal group exhibited abundant Proteobacteria than those in the Cont, Pro, and ProSal groups. Salmonella infection downregulated gene expression of Occludin, zonula occludens-1 (ZO1), and Mucin 2 in the jejunum and Occludin and Claudin in the ileum. Moreover, the Sal group increased gene expression of interferon-γ (IFN-γ), interleukin-6 (IL-6), IL-1β, and lipopolysaccharide-induced tumor necrosis factor-alpha factor (LITAF) and reduced levels of transforming growth factor-β4 and IL-10 compared with the other groups (p<0.05). However, chickens receiving probiotic diets increased Lactobacillaceae abundance and reduced Enterobacteriaceae abundance in the ceca. Moreover, supplementation with probiotics increased the mRNA expression of Occludin, ZO1, and Mucin 2 in the ileum (p<0.05). In addition, probiotic supplementation downregulated the mRNA levels of IFN-γ (p<0.05) and LITAF (p = 0.075) and upregulated IL-10 (p = 0.084) expression in the cecal tonsil. Conclusion: The administration of multi-strain probiotics modulated intestinal microbiota, gene expression of tight junction proteins, and immunomodulatory activity in broiler chickens.

Spontaneous tonsillar bleeding is a rare condition in ENT unit. Almost reported cases have been related to infection of tonsils. Prior to introduction of antibiotics, spontaneous tonsillar bleeding was usually related to superficial capsular bleeding due to acute or chronic tonsillitis. The presented case is a 36-year old healthy man without history of acute, chronic tonsillitis, and coagulation disorder who complained of dyspnea and oropharyngeal foreign body sensation after vomitting. Examination revealed a reddish polypoid mass of the right tonsil. Furthermore, the mass pushed uvula and tongue base, caused nearly total obstruction of oropharynx. All rountine laboratory test results were within normal limits. Computed tomography (CT) showed low density mass of attached in upper pole of right tonsil without enhancement. We performed tonsillectomy including the reddish polypoid mass under general anesthesia. The pathology revealed lymphoepithelial tissue with reactive hyperplasia. This is the first reported tonsillar hematoma presenting as a large oropharyngeal mass which was caused by vomitting.

The present study was carried out to investigate the pathogenicity and pathogenesis of wild rats(Rattus norvegicus), trapped in nature, intranasally infected with Aujeszky's disease virus(ADV/NYJ-1-87) by histopathology, immunohistochemistry and in situ hybridization(ISH). Fifteen rats inoculated intranasally were roughened haircoat, anorexia, listlessness, and depression second day after inoculation, and three rats died in 66-72 hours. Eight rats showed severe pruritus at the face that was accompanied by frequent face-washing movements of the forelegs, and then became violent and spasmodic for an hour or until they died. Four rats slowly recovered after showing mild clinical signs of the disease. Microscopic lesions in infected rats were characterized by meningitis, perivascular round cell infiltration, focal gliosis, and neuronal degeneration and necrosis. And intranuclear inclusion bodies were frequently detected in the cerebral cortex and medulla. Positive reaction to ADV by immunohistochemistry and ISH were detected in the following areas : trigermimal ganglion, brain, tonsil, nasal mucosa, spleen, lung and liver. The result has suggested that ADV intranasally infected in wild rats is followed by replication in epithelial calls of nasal mucosa and tonsil, then invade local lymph nodes by way of the lymphatics. It is also believed that the virus invades bipolar olfactory cells and trigerminal ganglion; and then spread into central nervous system.

Macrophage inflammatory protein $(MIP)-1{\alpha}$ is a cytokine which produces wide range of bioactivities such as proinflammatory, immunomodulatory, and hematopoietic modulatory actions. To determine whether $MIP-1{\alpha}$ acts as a negative regulator on the functions of lymphocyte, $[^3H]$-thymidine incorporation test and flow cytometric analysis were performed by using human tonsil T cell, human peripheral blood T cell, and murine cytolytic T lymphocyte (CTL) line CTLL-2, The results were as follow. 1. When human tonsil T lymphocytes were stimulated with anti-CD3 monoclonal antibody (mAb), rate of T cell proliferation was about four times increased. 200ng/ml of $MIP-1{\alpha}$ inhibited anti-CD3 mAb-mediated T cell growth as much as 60% (P<0.05). 2. The suppression of human peripheral T cell proliferation produced by $MIP-1{\alpha}$ was dramatic, but variable among T cells derived from different individuals $(40%{\sim}90%)$. 3. $MIP-1{\alpha}$inhibited the proliferation of murine CTL line CTLL-2 as much as 75%(P<0.001). 4. When the $MIP-1{\alpha}$ was added to human peripheral T cell, cell proporation of $CD4^+$ helper T cell and $CD8^+$ CTL were not noticeably affected. The expression level of CD4, not of Cd8, however, was down regulated by $MIP-1{\alpha}$ treatment $(27%{\sim}82%)$.

Two cases of classical swine fever (CSF) disease have broken out in Cheolwon (7 April, 2002). The suspected pig herds were huddled together because of high fever (over $40^{\circ}C$) and showed remarkable decrease of the leukocytes. The staggering gait related to posterior weakness, constipation and lethargy, hyperemia, hemorrhagic lesions (on the skin, muzzle, ears, limbs, tail and inner part of legs) and conjunctivitis with dirty streaks below the eyes were observed. The inflammation in the lung, infarction in the spleen, swelling and hemorrhage in lymph nodes, kidney, intestine, heart and cheese like purulent inflammation of the tonsil were observed. The ulcers of the colon were also detected. Several clinical and laboratory techniques including blood test, histo-pathological examinations, indirect fluorescent antibody (IFA) test and RT-PCR test were applied to diagnose the disease. Inoculation test on PK-15 cell was also performed. The necrosis of the lymphatic cells and infiltration of the vessel circumferential cells in the brain and lymph organs were commonly viewed. The proliferation of the glia cell (gliosis) in the lymph was particular. Cytopathogenic effect (CPE) and specific fluorescent-bright-green areas (with IFA) appeared in PK-15 cells inoculated with suspected blood plasma. The IFA test on the epithelial and mucous membrane cells of tonsil was positive. RT-PCR technique required more working hours and labor than other techniques in this examination but it was useful because of the sensitivity to the CSF viral gene.

Low pathogenic avian influenza (LPAI; H9N2) and Newcastle disease (ND) are economically important poultry diseases in Korea. In this study, we investigated pathological features and virus distribution in the lymphoid tissues of chicks experimentally infected with H9N2 and/or ND virus. Six-weeks-old SPF chickens were divided into 4 groups, Control (C), H9N2 (E1), NDV (E2), and H9N2+NDV (E3). E1 group was challenged with 0.1 ml A/Kr/Ck/01310/01 (H9N2) $10^{5.6}$ $EID_{50}$ intranasally, E2 group was challenged with 0.5 ml KJW (NDV) $10^{5.0}{\sim}10^{6.0}$ $ELD_{50}$ intramuscularly, and E3 group was challenged with H9N2, followed 7 days later by NDV. In histopathological examination, E1 group showed depletion and necrosis in bursa of Fabricius, thymus, cecal tonsil, and spleen, whereas E2 and E3 groups were noted severe lymphocyte depletion and necrosis with destruction of lymphoid organs structures. In TUNEL assay, apoptotic bodies were detected in lymphoid organs of all experimental groups, which was most severe in E3 group. H9N2 and ND viruses were predominantly detected in cecal tonsil of E1, E2, and E3 groups by PCR and immunohistochemistry (ICH). In conclusion, co-infection of H9N2 with NDV caused severe pathologic lesions and apoptosis in lymphoid tissues compared to single infections.

Background Reconstruction after removal of a malignant tumor in the head and neck region is crucial for restoring tissue integrity, function, and aesthetics. We retrospectively analyzed patients who underwent intraoral reconstruction surgery using radial forearm free flaps (RFFF) and anterolateral thigh free flaps (ALT) at a single institution to provide more information supporting the choice of a reconstruction method after removal of head and neck cancer. Methods The charts of 708 patients who underwent head and neck reconstruction between 1998 and 2018 at the Department of Plastic and Reconstructive Surgery at our institution were retrospectively reviewed. Patients' age, sex, and history of radiation therapy, diabetes mellitus, and smoking were retrieved. The primary cancer site, types of defects, and complications were investigated. Results Overall, 473 and 95 patients underwent reconstruction surgery with RFFF and ALT, respectively. RFFF was more often used in patients with cancers of the pharynx, larynx, esophagus, or tonsil, while ALT was more frequently used in patients with cancers of the mouth floor with tonsil or tongue involvement. The proportion of patients undergoing ALT increased gradually. Flap failure and donor site morbidities did not show significant differences between the two groups. Conclusions RFFF and ALT flaps resulted in similar outcomes in terms of flap survival and donor site morbidity. ALT can be an option for head and neck reconstruction surgery in patients with large and complex defects or for young patients who want to hide their donor site scars.

Pathological tissue fixation using formalin has been widely used for histological samples in many hospitals and institutions. In general, formalin fixatives were either manufactured in laboratories or purchased commercially because of the risks and environmental concerns of handling organic compounds. In this study, the efficacy of three kinds of commercially purchased and one laboratory-made formalin fixative was compared in the PCR-based molecular diagnosis using the extracted DNA from formalin-fixed paraffin-embedded (FFPE) tissues. The quality of extracted DNA from FFPE tonsil tissues with four kinds of formalin solutions was evaluated, and PCR for beta-globin gene and microsatellite instabilities (MSI) tests for pentaplex panel markers were performed using the extracted DNA. There was no difference in PCR and MSI tests as molecular diagnoses regardless of the types of formalin used in this study. However, the total amount and average length of double-stranded DNA extracted from FFPE tonsil tissue showed significant differences according to the type of formalin fixative. Optimized formalin fixatives and methods for DNA extraction might be sophisticated to extract good quality DNA from the small size of specific tissue samples. Further studies are needed to select the most effective formalin fixative for histology and molecular pathology using human FFPE tissues.
