OBJECTIVES: Cadherin/catenin adhesion complex is fundamentally involved in epithelial cancer invasion and metastasis. E-cadherin and EGFR colocalize on the basolateral membrane of epithelial cell and EGF down-regulate E-cadherin expression. In the invasion and metastasis of cancer, E-cadherin expression is decreased and growth factors receptor is overexpressed. The present study was aimed to find the role of E-cadherin, beta-and gamma-catenin, growth factors and its receptors in cervical cancer cell lines. METHODS: The cervical cancer cell cultures were treated with different time duration of EGF 30 ng/ml and TGF-a 10 ng/ml(0, 10 min, 20 min, 30 min, 1 hr, 2 hr, 4 hr, 8 hr, 24 hr). The change in cancer cell morphology and the changes in E-cadherin, beta- and gamma-catenin, EGFR and activated EGFR expression were studied with a western blot analysis and an immunoprecipitation. RESULTS: Through a western blot analysis, E-cadherin 120 kDa band and EGFR 170 kDa band were expressed in CaSki, HT-3 and ME-180 cell line, which showed epithelial contact growth. 1n these 3 cell lines, expression of E-cadherin did not decrease with time dependent manner. after the treatment of EGF and TGF- alpha. The expression of EGFR decreased and activated EGFR expression increased in 30 minutes to 1 hour but decreased subsequently. When the cells treated with EGF, there were no change in beta-and gamma-catenin expression with there dependent manner. The tyrosine phosphorylation of beta-and gamma-catenin increased in 30 minutes to 1 hour but decreased subsequently with activated EGFR. CONCLUSION: This study showed that an activated EGFR which has involved with tyrosine phosphorylation of beta- and gamma-catenin influenced by growth factors rather than expression of E-cadherin, has a role in the invasion and metastasis of the cervical cancer.

Ocular rosacea is the eye manifestations of rosacea, which involves the lids, conjunctiva, and cornea. A recent study revealed that all patients with cutaneous rosacea had some degree of ocular involvement which is often undiagnosed. It is difficult to make a diagnosis of ocular rosacea because it lacks clinical or pathological hallmarks. However, early diagnosis and treatment are emphasized to decrease morbidity and prevent potential blindness. We report a case of ocular rosacea in a 49 year-old man who showed blepharoconjunctivitis, keratitis, and cutaneous manifestations of persistent erythema, telangiectasia, and papules. The ocular symptoms and signs had improved significantly with tetracycline therapy.

OBJECTIVES: Interleukin-6 is a pleiotrophic cytokine that is not only a mediator in major immunologic reactions but also a growth factor of keratinocytes. We studied IL-6 mRNA expression in cervical cancer, CIN and normal cervix. And we questioned whether its expression is related to cervical carcinogenesis and other prognostic factors. METHODS: The normal cervical and cervical cancer tissues were taken from healthy women (n=16), and the patients with CIN (n=36) and cervical cancer (n=36). The IL-6 mRNA expression was examined by quantitative competitive PCR after polymerase chain reaction amplification of reverse transcriptase copies of RNA transcripts (RT-PCR). RESULTS: There was no statistically different among cervical cancer, CIN and normal cervix (p>0.05). The IL-6 mRNA expression was not different according to the grades of CIN. Its expression was not correlated with the stage of cervical cancer, size of tumor, and histopathologic type (p>0.05). CONCLUSION: These results suggested that IL-6 mRNA expression might not be associated with the cervical carcinogenesis and prognosis of cervical cancer.

OBJECTIVE: The aim of this study was to investigate whether embryonic stem (ES) cells can be established from isolated blastomeres of mouse embryos. METHODS: Blastomeres were separated from mouse (C57Bl/6J) 2- or 4-cell embryos. Isolated blastomeres or whole 4-cell embryos were co-cultured with mitosis-arrested STO feeder cells in DMEM supplemented with recombinant murine leukemia inhibitory factor and ES-qualified fetal bovine serum. After the tentative ES cell lines were maintained from isolated blastomeres or whole embryos, some of them were frozen and the others were sub-cultured continually. Characteristics of tentative ES cell lines as were evaluated for specific gene expressions with immunocytochemistry and RT-PCR. RESULTS: One ES cell line (3.0%) was established from isolated blastomere of 2-cell embryo and one cell line (4.0%) from isolated two blastomeres of 4-cell embryo. And five cell lines (16.7%) were established from whole 4-cell embryos. Both cell lines from isolated blastomere and whole embryo expressed mouse ES cells specific markers such as SSEA-1, Oct-4 and alkaline phosphatase. Marker genes of three germ layers were expressed from embryoid bodies of both cell lines. CONCLUSION: This study suggests that mouse ES cells could be established from isolated blastomeres, although the efficiency is lower than whole embryos. This animal model could be applied to establishment of autologous human ES cells from biopsied blastomeres of preimplantation embryos in human IVF-ET program.

PURPOSE: The study assessed the effect of exogenous surfactant on oxygen and ventilator requirements and long-term prognosis of neonates with respiratory deterioration due to pulmonary hemorrhage. METHODS: From March 2007 to March 2011, neonates with respiratory deterioration due to pulmonary hemorrhage in Saint Mary's Hospital were identified from the database. Among 20 patients with pulmonary hemorrhage, 10 patients received surfactant therapy and the other 10 did not. We compared outcomes of these two groups. The primary outcome was changes in respiratory status following surfactant therapy, as reflected by oxygen index (OI), fractional inspired oxygen (FiO2) and mean airway pressure (MAP). Secondary outcomes were the duration of ventilation, nasal continuous positive airway pressure (NCPAP), oxygen inhalation days, progression to severe bronchopulmonary dysplasia or death, and retinopathy of prematurity, which required laser therapy. RESULTS: Surfactant treatment group had higher FiO2, MAP, and OI than the non-treatment group during pulmonary hemorrhage. But, there were no differences in FiO2, MAP, and OI after 2 hours of pulmonary hemorrhage between the two groups. There were no significant side effects during surfactant treatment in the surfactant treatment group. Surfactant treatment group had fewer ventilator days, NCPAP days (P<0.05) and a tendency towards shorter oxygen days than the non-treatment group (P=0.09). Also, the surfactant treatment group had less severe bronchopulmonary dysplasia (BPD) or death than the non-treatment group (10% vs. 70%, P<0.05). CONCLUSION: Exogenous surfactant appears to be a useful adjunctive therapy with neonates of severe respiratory deterioration due to pulmonary hemorrhage. Also, exogenous surfactant treatment dose not seen to be associated with any significant side effects during the therapy.

Diffuse aspiration bronchiolitis is defined as a clinical entity characterized by a chronic inflammation of bronchioles caused by recurrent aspiration of foreign particles. Clinical symptoms are bronchorrhea, bronchospasm, and dyspnea, and chest radiographs show the presence of regional or disseminated srnall nodular shadows and hyperlucency. Chest CT should help in detecting diffuse nodular shadows of bronchiolitis. Pathologic findings of diffuse aspiration bronchiolitis are characterized by localization of chronic mural inflammation with foreign body reaction in bronchioles. Recurrence of small amounts of aspiration might play an important role in the pathogenesis of diffuse aspiration bronchiolitis. We report a case of diffuse aspiration bronchiolitis in a 4-month- old female infant who had recurrent aspiration due to dysphagia and presented with recurrent fever, dyspnea and wheezing. She showed typical radiologic and histologic findings compatible to diffuse aspiration bronchiolitis. She was improved with treatment of nasogastric tube feeding. We emphasize the importance of recognizing this disease entity and differentiating it from pulmonary diseases associated with bronchospasm. (J Korean Pediatr Soc 2000;43:842-845)

Perioral dermatitis is a facial dermatoses affecting the nasolabial folds, the chin, and the upper lip with sparing of a rim of skin at the vermilion border. The classic distribution is of the perioral area, but the glabella, eyelids and even forehead may be affected. In the patients with the periocular variety, the history, course, and response to treatment are exactly the same as in those with classic perioral dermatits. Herein, we report a case of perioral dermatitis involving the eyelids in a 23-year-old man who had used topical corticosteroids but experienced symptom aggravation and improvement after doxycycline treatment.
