The alterations in the localization of keratinocyte membrane glycoconjugates in allergic contact dermatitis were investigated in guinea pig skin treated with topical application of 2.4-dinitro-chlorobenzene. We employed the avidin-biotin complex(ABC) method for the detection of localization of 10 commercially available lectins labelled with biotin: Con-A, SBA, WGA, DBA, UEA-1, RCA-1, PNA, HP, MPA, and ECA. Staining with WGA showed a remarkably decreased intensity in basal and spinous layers of the allergic skin in comparison to those of the control skin, suggesting loss of terminal sialic acids in cell membrane glycoconjugates. The other lectins showed no remarkable difference in the staining patterns between the normal and the allergic ski. The results suggest that epidermal cell membrane glycoconjugates undergoes selective perturbations in acute allergic contact dermatitis, and that the keratinocytes might be an active part of the cutaneous immune system.

PURPOSE: The purpose of this study was to investigate the relationships among variables of body image, self-esteem and depression in college female students according to the normal and overweight. METHOD: The subjects of this study consisted of 245 college female students. The data was collected through personal interviews using questionnaires from May to June of 2001. The data was analyzed by the SPSS computer program, and it included descriptive statistics, x2-test, t-test and the pearson correlation coefficient. RESULT: Demographics provided a significant difference in grade, household income, weight control experience. There was a perceived health status difference, according to the normal and overweight subjects. There was a significant difference in body image, self-esteem and depression between the two groups. There was a significant positive correlation between body image and self-esteem, and negative correlation between body image and depression, and self-esteem and depression in college female students. CONCLUSION: The Findings of this study give useful information to construct further studies in intervention program relating overweight control for college female students.

A clinico-pathologic study with an immunohistochemical examination for c-erbB-2 expression in 54 cases of ductal carcinoma in situ and 16 cases of Paget's disease of the breast was performed. c-erbB-2 oncoprotein overexpression was observed in 45% (24/54) and 88% (14/16) of ductal carcinoma in situ and Paget's disease, respectively. The overexpression of c-erbB-2 oncoprotein was significantly correlated with the nuclear grade of tumors and inversely with the status of the estrogen receptor. c-erbB-2 was positive in 4 out of 5 patients with metastasis to axillary lymph nodes and 3 out of 4 patients who died of the disease. Prognostic significance of c-erbB-2 oncoprotein in ductal carcinoma in situ was highly suggested. The expression of c-erbB-2 oncoprotein in Paget's disease was well correlated with coexisting infiltrating or in situ ductal carcinoma. The high positive rate of c-erbB-2 oncoprotein in ductal carcinoma with Paget's disease could be understood with a recent hypothesis that c-erbB-2 oncoprotein is involved in promotion of cell motility and the spread of carcinoma cells.

Nowday, ionizing radiation is one of the methods eradicating the uterine cervical malignancy. However radiation alone or in combination with surgery have an effect on normal tissue as well as the malignant cells, and their changes have been well described in other countries. Unfortunately, the history of radiation modality for cancer treatment is relatively short and the reports about radiation induced changes are limited in our country. We evaluated the radiation-induced changes in cervico-vaginal smears of 107 uterine cervical cancer patients obtained from March, 1985 to October, 1987. Most patients had been received 5,400 Rads of external radiation and intracavitary radiation. Patient's age ranged from 30 to 67 years old. Of 107 cases, 24 cases were normal, 72 cases showed benign radiation changes, 7 cases revealed radiation dysplasia, and residual and recurrent carcinomas found in one and 3 cases, respectively. Cytoplasmic and nuclear enlargement were the most common and noted in 57 and 38 cases, respectively. Vacuolization and polychromasia of the cytoplasm were identified in 43 and 30 cases, respectively. The most common histiocytic change was multinucleation, which was found in about one third. The radiation changes of the cytoplasm and nuclear enlargement persisted for a long time after completion of radiation, however, nuclear degeneration and multinucleation gradually disappeared after 6 months. The inflammation in background prolonged for a long time but degeneration disappeared after 6 months. The biologic significance of post-radiation dysplasia could not evaluated because of short follow up period.

Malignant tumor is found in 1-2% of ovarian benign cystic teratomas. Among these malignant neoplasms, squamous cell carcinoma is by far the most common malignancy, whereas the incidence of struma ovarii is less than 5% in mature teratoma. As far as concerned the struma ovarii, a very small percentage is associated with carcinoid, mucinous or serous cystadenoma, or Brenner tumor. However, any reports of struma ovarii associated with squamous cell carcinoma in the same ovary could not be found in English literature. Recently we have experienced a case of squamous cell carcinoma and struma ovarii arising in an ovarian benign cystic teratoma in 72 year old female patient.

PURPOSE: Although it has been suggested that pulmonary tuberculosis (TB) is associated with increased risk of lung cancer, the exact mechanism is not clearly identified. We investigated the effect of pulmonary TB on the epidermal growth factor receptor (EGFR) mutational status and clinical outcome in patients with pulmonary adenocarcinoma. MATERIALS AND METHODS: We reviewed data of patients diagnosed with pulmonary adenocarcinoma harboring EGFR mutations and treated at our institution from 2008 to 2015. We divided our population into two groups: patients with pre-existing TB lesions on chest computed tomography scan (TB group) and those without the lesions (non-TB group). We compared the differences in EGFR mutational status, response to tyrosine kinase inhibitors (TKIs) and survival between the two groups. RESULTS: A total of 477 patients with pulmonary adenocarcinoma were analyzed. One hundred eighty-three patients (39%) had EGFR-mutated tumors and 100 (21%) patients had pre-existing TB lesions. The frequency of EGFR mutation was significantly higher in the TB group compared with the non-TB group (56% vs. 34%, p=0.038). Pre-existing TB lesions were independently associated with more frequent EGFR mutations in multivariate analysis (odds ratio, 1.43). In addition, both the progression-free survival (9.1 months vs. 11.6 months, p=0.020) and the overall survival (19.4 months vs. 24.5 months, p=0.014) after first-line EGFR-TKIs were significantly shorter in the TB group than in the non-TB group. CONCLUSION: Previous pulmonary TB may be associated with more frequent EGFR mutations and poorer treatment response to EGFR-TKIs in patients with pulmonary adenocarcinoma.

BACKGROUND: Although targeted therapy and immuno-oncology have shifted the treatment paradigm for lung cancer, platinum-based combination is still the standard of care for advanced non-small cell lung cancer (NSCLC). Pemetrexed continuation maintenance therapy has been approved and increasingly used for patients with nonsquamous NSCLC. However, the efficacy of this strategy has not been proven in patients without driving mutations. The objective of this study was to compare the clinical benefit of pemetrexed continuation maintenance to conventional platinum-based doublet in epidermal growth factor receptor (EGFR)-negative lung adenocarcinoma. METHODS: A total of 114 patients with EGFR-negative lung adenocarcinoma who were treated with platinum doublet were retrospectively enrolled. We compared the survival rates between patients received pemetrexed maintenance after four-cycled pemetrexed/cisplatin and those received at least four-cycled platinum doublet without maintenance chemotherapy as a first-line treatment. RESULTS: Forty-one patients received pemetrexed maintenance and 73 received conventional platinum doublet. Median progression-free survival (PFS), which was defined as the time from the day of response evaluation after four cycles of chemotherapy to disease progression or death, was significantly higher in the pemetrexed maintenance group compared to conventional group (5.8 months vs. 2.2 months, p<0.001). Median overall survival showed an increasing trend in the pemetrexed maintenance group (22.3 months vs. 16.1 months, p=0.098). Multivariate analyses showed that pemetrexed maintenance chemotherapy was associated with better PFS (hazard ratio, 0.73; 95% confidence interval, 0.15–0.87). CONCLUSION: Compared to conventional platinum-based chemotherapy, premetrexed continuation maintenance treatment is associated with better clinical outcome for the patients with EGFR wild-type lung adenocarcinoma.

For many years, the histogenesis of the granular cell tumor was controversial and this resulted in the tumor being given more than 20 synonyms. Abrikossoff, reporting on the fiist granular cell tomor, favored a muscle origin, but other authora have postulated a fibroblastic or a histiocytic origin. Recently, the concept of Schwann cell origin, supported by electron microscopic studies and immunohistochemistry of S-100 protein, has gained wider recognition. Approximately 90 cases of esophageal granular cell tumor have been reported in the literature, representing about 2% incidence of all reported granular cell tumor, In Korea, only four cases of granular cell tumors were reported in the literatures including the cases occuring in the cecum, colon, and anus until now. Recently we experienced 46-years old women with granular cell tumor of the esophagus, which might be the second case in Korean literature.

PURPOSE: To evaluate lung parenchymal change as seen on chest radiographs and high-resolution CT (HRCT) afterthe resolution of adenovirus pneumonia (a common cause of lower respiratory infection in infants and children),and the usefulness of HRCT during follow-up. MATERIAL AND METHODS: Four to 13(mean, 8) months after recovery, tenpatients infected with adenovirus pneumonia underwent HRCT and chest radiographs. Eight were boys and two weregirls, and their mean age was 26(range, 14-45) monthes. Adenovirus pneumonia had been confirmed by viral isolationin culture or serologic test. CT scanning was performed during quiet breathing ; collimation was 2mm and theinterval from apex to diaphragm was 5-10mm. Lung settings were 1600 HU (window width) and -700 HU(level). CTfindings were assessed and compared with chest radiographs by two chest radiologists, who reached a consensus. Thepatients were clinically followed up for one year. RESULT: On chest radiographs, hyperlucent lung was seen in 8of 10 patients (80%) ; in one other there was partial collapse, and in one, findings were normal. The most commonHRCT finding was a mosaic pattern of lung attenuation with decreased pulmonary vascularity in the area of lowerattenuation ; this was seen in 8 of 10 patients (80%). Other findingss were partial collapse, bronchiectasis, andbronchial wall thickening, each seen in two patients, and reticulonodular density, seen in one. In two patientsHRCT findings were normal ; in one of these, chest findings were noraml but a mosaic pattern of lung attenuationwas found in all lobes. During follow-up, three patients wheezed continously. CONCLUSION: In cases of adenoviruspneumonia, HRCT demonstrated more specific parenchymal change than did chest radiographs ; a mosaic pattern oflung attenuation was seen, with decreased pulmonary vascularity in areas of lower attenuation ; bronchiectasis,bronchial wall thickening, and reticulo-odular density were also noted. These findings were presumably due tobronchiolitis obliterans, a well known complication of adenovirus pneumonia, and are prognostically helpful.
