This study is to provide details of the unique anatomical features on the alar lobule region in Korean nose. We hypothesized that the anatomy of this area differs according to the shape of the alar lobule. Based on the prominence and roundness of alar lobules, they were classified into horizontal and vertical types. A total of 20 fresh cadaver noses(10 for each type) were dissected. The anatomical differences between the horizontal and vertical types were investigated by gross and histologic studies. The alar lobule is composed of three layers, i.e., external skin, muscle, and vestibular skin. Profound differences between the two alar lobule types were evident in terms of the volume of the dilator naris anterior muscle, the insertion of the dilator naris posterior muscle, and the thickness of the external skin at the lateral end of the alar circumference. The horizontal type has a greater volume of dilator naris anterior muscle, an additional insertion of the dilator naris posterior muscle, and thicker external skin at the lateral end of the alar circumference than the vertical type. The Korean nose differs anatomically and morphologically from the Caucasian nose. This study shows that there are anatomic differences between the horizontal and vertical types of alar lobules in Korean nose.

Toxoplasma gondii atypical type II genotype was diagnosed in a pet peach-faced lovebird (Agapornis roseicollis) based on histopathology, immunohistochemistry, and multilocus DNA typing. The bird presented with severe neurological signs, and hematology was suggestive of chronic granulomatous disease. Gross post-mortem examination revealed cerebral hemorrhage, splenomegaly, hepatitis, and thickening of the right ventricular free wall. Histologic sections of the most significant lesions in the brain revealed intralesional protozoan organisms associated with malacia, spongiform changes, and a mild histiocytic response, indicative of diffuse, non-suppurative encephalitis. Immunohistochemistry confirmed the causative organisms to be T. gondii. DNA isolated from the brain was used to confirm the presence of T. gondii DNA. Multilocus genotyping based on SAG1, altSAG2, SAG3, BTUB, GRA6, c22-8, c29-2, L358, PK1, and Apico markers demonstrated the presence of ToxoDB PCR-RFLP genotype #3 and B1 gene as atypical T. gondii type II. The atypical type II strain has been previously documented in Australian wildlife, indicating an environmental transmission route.

The tumorous type of endobronchial tuberculosis was reponed to be 5 to 10% in the bronchoscopic examination. It was protruding mass that tuberculosis mediastinal lymph nooe ruprured into the bronchial lumen. Generally histologic examination has been performed for purpose of differentiation, because the tuberculosis type of endobronchial tuberculosis simulate lung cancer in bronchoscopic finding. A case considering operation similar to bronchial adenoma in the bronchoscopic finding was confirmed to endobronchial tuberculosis by JX5itive AFB and disapperance of mass after antituberculosis medication. Case history was presented and reviewed.

It has been suggested that the endoscopic color of intramucosal gastric carcinoma is correlated with mucosal vascularity within the carcinomatous tissue. The development of electronic endoscopy has made it possible to quantitatively measure the mucosal hemoglobin volume, using a hemoglobin index. The aim of this study was to make a software program to calculate the hemoglobin index (IHb) and then investigate whether the mucosal IHb determined from the electronic endoscopic data is a useful marker for evaluating the color of intramucosal gastric carcinoma, in particular with regard to its value for discriminating between the histologic types. The mean values of IHb for the carcinoma (IHb-C) and the mean values of IHb for the surrounding non-cancerous mucosa (IHb-N) were calculated in 75 intestinal-type and 34 diffuse-type gastric carcinomas. Then, we analyzed the ratio of the IHb-C to IHb-N. The mean IHb-C/IHb-N ratio in the intestinal-type carcinoma group was higher than that in the diffuse-type carcinoma group (1.28$\pm$0.19 vs. 0.81$\pm$0.18, respectively, p<0.001). When the cut-off point of the C/N ratio was set at 1.00, the accuracy rate, the sensitivity, the specificity, and the positive and negative predictive values of a C/R ratio below 1.00 for the differential diagnosis of diffuse-type carcinoma from intestinal-type carcinoma were 94.5%, 94.1%, 94.7%, 88.9% and 97.3%, respectively. IHb is useful for quantitative measurement of the endoscopic color in intramucosal gastric carcinoma and the IHb-C/IHb-N ratio would be helpful in distinguishing diffuse-type carcinoma from intestinal-type carcinoma.

Objectives : The purpose of this study is to evaluate effect of suppressing the expression of cyclo-oxygenase-type-2 (COX-2) as a consequence of inhibition macrophage migration inhibitory factor (MIF) activation by $Sambucus$ $williamsii$ $Hance$ (SWH) pharmacopunctureon rheumatoid arthritis (RA). Methods : In vitro test, synoviocytes extracted from type II collagen-induced arthritis (CIA) mouse's knee joint were cultivated After that, each well of synoviocytes was mixed with the extract of SWH at the dosage of $0.4mg/m{\ell}$, $0.6mg/m{\ell}$, $0.8mg/m{\ell}$, and $1.0mg/m{\ell}$ respectively, and cultivated for 24 hours after the addition. Reverse transcriptase - polymerase chain reaction (RT-PCR) is used to investigate the expression of MIF, Tumor necrosis factor (TNF)-${\alpha}$, COX-2 mRNA. $In$ $vivo$ test, thirty DBA female mice were used, and each ten mice were allocated into three group; normal group, CIA-elicitated group, and group treated with SWH pharmacopuncture on it's the point of $ST_{35}$ after CIA elicitation. It is investigated that change of mice foot thickness, histologic change of sliced synovial joint of mouse, and extent change of MIF, TNF-${\alpha}$, COX-2 in synovial membrane. Results : $In$ $vitro$ test, the expressions of cytokine(MIF, TNF-${\alpha}$, COX-2) mRNAs related to RA were dose-dependent decreased. In the SWH pharmacopuncture group, foot thickness and histologic change of sliced synovial joint were decreased comparing with CIA-elicitated group's change. In the SWH pharmacopuncture group, the suppression of MIF, TNF-${\alpha}$, COX-2 in synovial membrane was clearly shown comparing with CIA-elicitated group's change. Conclusions : It might be suggested that SWH pharmacopuncture mitigate tissue damage originated from rheumatoid arthritis by suppressing the expression of COX-2 as a consequence of inhibition MIF activation.

There have been few large scale surveys of salivary gland tumors, because the salivary gland tumors comprised less than 3 percent of all neoplasms of the head and neck. Also there is a problem that the incidences of specific types of tumors have the variation according to the geographic regions. ]'nother Korean reports about salivary gland tumor, they only treated about 100 cases only. Objectives : The purpose of this study is to identify the frequency and clinical characteristics of salivary gland tumors and to compare with other Korean reports. Materials and Methods : We had performed to analyze 387 cases of salivary gland tumors from 1983 to June 1997, were reviewed in histopathological and clinical aspects. The diagnoses of individual tumors were based on the World Health Organization classification. Tumors were analyzed according to the histologic type site, age and sex. Results : The majority (79.1%) of cases occurred in the major salivary glands and 20.9% in the minor. The parotid gland was the most frequent site with 52.4％ and submandibular glands with 26.3%. Benign tumors were 79.3% of the tumors and malignant tmon were 20.7%. The most frequent tumor was pleomorphic adenoma occupied 63.8% of the total and frequency percent of histologic type of 98 malignant tumors showed 35.7% of mucoepidermoid carcinomas, 24.5% of adenoid cystic carcinomas. Overall gender with female predominance with 1 : 1.4 of male to female ratio. The average age of patients was 42.8 years. The most frequent chief complaint was a palpable mass. The duration of the symptom was shorter in the malignant salivary gland tumors (26.7 months) than in the benign salivary gland tumors (38.2 months). Conclusion : Comparing to the previous Korean reports, the present study confirms that the incidence of salivary gland tumor was lower in the parotid gland, and was higher in the submandibular and minor salivary glands.

Desmoplastic ameloblastoma is a rare histologic variant of ameloblastoma. It shows important differences in anatomic distribution, histologic appearance, and radiographic findings compared with the general type of ameloblastoma. It is histologically characterized by an abundance of densely collagenous stroma and radiographically a mixed radiolucent-radiopaque lesion. We present three cases of desmoplastic ameloblastoma. All the patients complained on buccal swelling with or without pain and the sites of occurrence were the anterior and the premolar region. Plain radiographs showed mixed radiopaque-radiolucent lesion with ill-defined or diffuse sclerotic margin and no external root resorption. Additionally, CT scans revealetl buccal expansion and relatively well-defined margin of the lesions. The clinical and radiographic features of the presented cases were compared with those of the desmoplastic ameloblastoma in the previous literatures.

Acinic cell carcinoma is a slow-growing solid neoplasm of salivary gland. Although their cytological and histological finding is bland-looking, their biological behavior is unpredictable. We experienced two cases of acinic cell carcinoma of the salivary gland diagnosed by fine needle aspiration biopsy and confirmed by tissue examination. They showed different clinical courses. We compared their cytologic and histologic findings. The first case was a right preauricular mass in a 58 year-old female of 3 years duration. The cytologic smear revealed sheets or small clusters of monotonous cells mimicking normal serous acinar cells with little cellular pleomorphism. She underwent superficial parotid lobectomy. The tumor was a well demarcated 1.5cm sized nodular mass without infiltration into surrounding parenchyme. The second case was a left submandibular mass in a 23 year-old male of 4 years duration. The smear showed more severe pleomorphism of the tumor cells than those of previous case. Excisional biopsy was done. The excised tumor was $5.5{\times}3.5{\times}3cm$ sized multilobulated solid mass with invasion into surrounding parenchyme. The tumor recurred after 20months, thus total excision of the mass and modified radical neck dissection was carried out. From the above findings, cytologic atypism, infiltrative growth pattern and type of initial therapy may be correlated with biologic behavior.

Ameloblastoma is the most common epithelial odontogenic tumor. It may show locally invasive behavior resulting in recurrence and malignancy. Therefore, appropriate diagnosis of this tumor is necessary. The aim of this study was to evaluate clinicopathological characteristics of ameloblastomas in an Iranian population. We present a 40-year retrospective study of patients diagnosed from 1971 to 2010 in the Department of Oral and Maxillofacial Pathology, Faculty of Dentistry, Mashhad, Iran. Information gathered from patient records included age, gender, tumor location and histologic type. The frequency of odontogenic tumors among all lesions was 2.08% and ameloblastoma with 88 samples demonstrated the greatest prevalence (41.5%). Regarding gender, 60% of samples occurred in males. The mean age of studied patients was $33.02{\pm} 15.74years$ with a peak of occurrence in the third decade of life. The most frequent location of tumor was the mandibles (93.2%). Eighty five (96.6%) tumors were recorded as benign and 3 (3.4%) as malignant. Of benign tumors, 62 (72.9%), 20 (23.5%) and 3 (3.6%) cases were of conventional, unicyctic and peripheral types, respectively. In contrast to most previous studies, the most common histologic subtype in the present study was plexiform. Knowledge of the incidence of ameloblastoma and its clinicopathologic features including most common location, gender and age distribution in different ethnogeographic backgrounds is necessary for accurate diagnosis and proper treatment.

Purpose: To analyze the prognostic factors for survivals and to evaluate the impact of postoperative whole pelvic radiotherapy (WPRT) on pelvic failure in patients with uterine sarcoma treated with radical surgery. Materials and Methods: We retrospectively analyzed 75 patients with uterine sarcoma who underwent radical surgery with (n = 22) or without (n = 53) radiotherapy between 1990 and 2010. There were 23 and 52 patients with carcinosarcoma and non-carcinosarcoma (leiomyosarcoma, 22; endometrial stromal sarcoma, 25; others, 5), respectively. The median follow-up period was 64 months (range, 17 to 269 months). Results: The 5-year overall survival (OS) and pelvic failure-free survival (PFFS) of total patients was 64.2% and 83.4%, respectively. Multivariate analysis revealed that mitotic count (p = 0.006) was a significant predictor of OS. However, factors were not found to be associated with PFFS. On analyzing each of the histologic subtypes separately, postoperative WPRT significantly reduced pelvic failure in patients with carcinosarcoma (10.0% vs. 53.7%; p = 0.046), but not in patients with non-carcinosarcoma (12.5% vs. 9.9%; p = 0.866). Among the patients with carcinosarcoma, 4 patients (17%) had recurrence within the pelvis and 3 patients (13%) had recurrence in other sites as an initial failure, whereas among the patients with non-carcinosarcoma, 3 patients (6%) experienced pelvic failure and 13 patients (25%) experienced distant failure. Conclusion: The most significant predictor of OS was mitotic count. Based on the improved PFFS after postoperative WPRT only in patients with carcinosarcoma and the difference in patterns of failure between histologic subtypes, optimal adjuvant treatment options should be offered to patients based on the risk of recurrence patterns.
