This study was undertaker to define the usefuness of preoperative CA-125 assay as a diagnostic bmor marker in differentiating malignancy from benign ovarian mass. Senun CA-125 were imneasured by Microparticle Enzyme Immunoassay(MEIA) in 94 patients with ovarian mass. The results were of follows ; 1. The mean value of preopentive senun CA-125 was 18.40u/ml in benign ovarian mass and 225.99u/ml in malignant ovarian mass (P<0.001). 2. The positive rete of Ca-125 in benign ovarian mass was 10%, compared 80% in malignant ovarian mass. 3. In analysis of histolovgic type, posisitive rate of serum CA-125 in malignant serous tumor was 82%, cornpared 50% in malignant mucinoins tumor. 2. No statistically significant correlation was observed between CA-125 value and patient's age. 5. The sensitivitiy, specifieity, positive predictive value & negative predictive value were 80%, 90%, 60% & 96%, respectively in cut off value, 35u/ml, And increasing cut off value 65u/ml, sensitivity, specificity, positive predictive value & negative predictive value were 40%, 96%, 67%, 90%, resqxetively. These data suggest the preperative serum CA-125 level correlate with maignant stattis in ovarian mass. And cut off value 35u/ml was better than 65u/ml in screening for ovarian cancer.

PURPOSE: To describe a case of exercise-induced anaphylaxis presenting with lower lid angioedema. CASE SUMMARY: A 35-year-old female patient for the past 3 years experienced lower lid edema in her left eye after exercising. In the treadmill exercise test, sneezing, coughing, and lower lid edema in her left eye appeared 13 minutes after initiating exercise. Additionally, contrast-enhanced computed tomography scan revealed minimal soft tissue thickening of the left inferior periorbital subcutaneous area with subtle enhancement after exercise. The serum immunoglobulin E (IgE) test showed elevated total IgE levels. The patient was diagnosed with exercise-induced anaphylaxis based on the above results. We informed the patient on her trigger factors and possible symptoms and prescribed an oral antihistamine and steroid. CONCLUSIONS: In patients presenting with facial edema or eyelid edema after exercise, the possibility of exercise-induced anaphylaxis should be considered. In addition, we have to aware of possibility of complication such as airway obstruction or a life-threatening condition, and it is needed to prevent a recurrence of anaphylaxis by cooperating with other department.

To develop a live vaccine candidate using an attenuated strain of Salmonella Typhimurium (ST), biochemical properties, plasmid profile, PFGE patterns and pathogenic analysis of the ST isolate were carried out after sequential passage of the ST isolate in porcine neutrophils. By the passage, the ability of the neutrophil-adapted isolate to utilize d-xylose was lost, while the ability of the strain to ferment trehalose was delayed after 2 or more days of the culture. Also, changes including deletion of the gene fragments were observed in PFGE analysis of the neutrophil-adapted isolates. Two plasmids, 105kb and 50kb, were cured in the strain passaged over 15 times in porcine neutrophils. The 50% of lethal dose (LD50) of the parent strain was changed from 1 x 10(5) LD50 to 6 x 10(6) LD50 by the passage in intraperitoneal injection of the strains into mice. These results suggested that bacterial genotypic and phenotypic responses might be globally altered depending on the inside environment of neutrophils.

OBJECTIVE: To ananlyze the direct effect of nitric oxide (NO), generated from sodium prusside (SNP) on the embryo developments in reproductive process. DESIGN: ova from mouse were treated to allow fertilization in in vitro culture. And the samples of fertilized ova were alloted into five alliqutos. Each alliquot was cultured in media treated with either concentration at 0 (n=92), 25microM (n=84), 50microM (n=80), 100microM (n=77), 500microM (n=54) of SNP. Main Outcome MEASURE: Rates of embryonal cell cleavages, viability and cell morphology were assessed during in vitro fertilization and culture. RESULTS: As analyse the cell cleavage at 24 hours after in vitro culture of fertilised egg in variuos NO concentration, all of egg cells of each alliquot were developed to 2~4 cell stage. But the alliquot of egg cells treated with 500microM, which were totally degenerated. And also all embryonal cells of each alliquot were developed to 8 cell stage and morula stage on culture continuosly. And the embryonal cells of each alliquot were analysed at 24 and 48 hours following the in vitro culture. The rates of cell fragmentation and fusion were 4.2+/-3.4% in control group which is not treated with NO, while experimental groups was high, as rated 23.4+/-6.2% in 25microM, 28.2+/-5.7% in 50microM and 32.1+/-6.4% in 100microM concentration of NO. Accordingly the rate of abnormal morphology of embryonal cell in control was lower significantly than that in each alliquot of experimental groups (p<0.05). And the degenerated rates of embryonal cells were 0% in control, 17.8+/-6.7% in 25microM, 23.6+/-4.7% in 50microM and 26.8+/-11.2% in 100microM at 8 cells and morula on culture of 48 and 72 hours. On the examination of embryonal cells developed to blastocyst through in vitro culture, the rates of degenerated cells were 16.8+/-7.2% in control, 37.5+/-6.2% in 25microM, 73.4+/-4.6% in 50microM, 100% in 100microM. CONCLUSION: This results suggeted that the No in any concentrations is harmful on embryos in view of morphology as well as viability of cell, and the toxicity of No on embryo is stronger at condition in higher concentration of NO.

BACKGROUND: Human papillomavirus (HPV) is known to cause of oropharyngeal squamous cell carcinoma (SqCC). HPV positive SqCCs overexpress p16 and are associated with better survival. Several markers of cell cycles and apoptosis have been reported as a prognostic value. We examined the prognostic value of HPV status, p16, cyclin D1, and Bcl-2 in patients with tonsillar SqCC. METHODS: Tissue microarrays were constructed in 56 cases of tonsillar SqCC for which we performed an immunohistochemistry and an in situ hybridization (ISH) of the HPV. RESULTS: Of the 56 cases, 31 (55.3%) were positive for p16 and 20 (35.7%) were positive for HPV ISH. The expressions of p16, cyclin D1, and Bcl-2 were not correlated with the clinicopathologic variables including smoking status, differentiation and pT- and pN-stages. The HPV ISH positive group showed a better overall survival than the HPV negative group (p=0.04), and the p16 positive group showed a better disease free survival (DFS) than the negative group (p=0.016). Cox regression analysis showed that only p16 positivity was an independent prognostic factor for DFS (p=0.03; hazard ratio, 10.1). CONCLUSIONS: Our results indicate that both p16 expression and HPV status are useful indicators for risk stratification in patients with tonsillar SqCC.

PURPOSE: In general, the depth of tumor invasion correlates with lymph node metastasis in gastric cancer, but some cases show a discrepancy between the tumor depth and nodal status. Therefore, this study was designed to investigate the factors affecting tumor growth patterns including the depth of invasion and lymph node metastasis. METHODS: The clinico-pathological characteristics of 1048 gastric cancer, from 1993 to 1999, were investigated. These cancer cases were divided into three groups: the early gastric cancer with lymph node metastasis (EP), the serosa infiltrated advanced cancer with no lymph node metastasis (SN), and the serosa infiltrated advanced gastric cancer with lymph node metastasis (SP) groups. The expression status of the proteins related with tumor growth, including matrix metalloproteinase-2 and 9 (MMP-2 and MMP-9), VEGF, nm23 and p53, were compared using immunohistochemical stain, p53 gene mutation, Microsatellite instability (MSI) and Loss of heterozygosity (LOH). RESULTS: There were 35 (3.4%) of the total cases in the EP group, and 10.1% in Early gatric cancer cases. The female ratio in the EP group was higher than in the SN group but this was not statistically significant. The most common gross types in the EP and SN groups were IIc and Borrmann type III, respectively, and the mean tumor size was largest in the SN group. The cell differentiation of the SN group was better than that in the EP group (68.6 vs. 41.2%). The levels of MMP-2 and -9 were higher in the SN and SP groups than those in the EP group. However, the levels of VEGF and nm23 between the groups were no different. The EP group had the highest degree of p53 mutation. There was no difference in the MSI and LOH expression status between the groups. CONCLUSION: There were some different growth patterns in the gastric cancers between the lymph node metastasis dominant (EP) and depth of infiltration dominant (SN) groups. MMP-2 and -9, tumor differentiation and mutated p53 gene exon may correlated with the tumor growth pattern. Further study is suggested to find the difference between the EP and SN groups, which could provide information on which factors determine nodal metastasis or the depth of a infiltration dominant growth pattern.

PURPOSE: Accurate diagnosis of group A streptococcal(GAS) pharyngitis and appropriate antimicrobial therapy are important, particularly to prevent nonsuppurative sequelae and to reduce the improper use of antibiotics. Because the clinical presentation of pharyngitis does not reliably predict the etiologic agent, when GAS infection is suspected, diagnosis should be based on the result of a throat swab culture or antigen-detection test with culture back-up. METHODS: We reviewed retrospectively the medical records of children diagnosed as GAS pharyngitis by throat swab culture from Jan. 1995 to Jul. 2000. Since Nov. 1998, specimens were also tested with the Abbott's Testpack+plus Strep A Kit. RESULTS: 121 patients were confirmed as GAS pharyngitis by throat culture. GAS pharyngitis predominantly occurred from 3 to 7 years of age with the peak incidence at 4 and 5 years of age. The disease was more frequent in late fall, winter and spring. Clinical manifestations were as follows; fever(89.9%), abnormal pharynx(94.3%), of which exudate in 33.6%, sore throat(85.3%), headache(78.1%), cervical lymphadenopathy(67.5%), abdominal pain(64.3%), and nausea or vomiting (55.0%). The sensitivity and specificity of rapid antigen test compared to throat culture were 96.4% and 95%, respectively. CONCLUSION: GAS pharyngitis occurred every year, and more frequently in late fall, winter and spring. It occurred with the greatest frequency in preschool children. The rapid antigen test can be a basis for clinicians to decide how to treat their patients before the culture results are proven, and can be helpful to judicious use of antibiotics as well.

OBJECTIVE: To study the clinical characteristics of pregnancy induced hypertension(PIH). METHODS: Five hundred seventy-five cases of PIH and 7,702 cases of normotensive pregnancies who were delivered their infants at Wonkwang University Hospital from January, 1994 to December, 1998 were selected for the study. The data were collected by review of the hospital record and the statistical analysis was performed using Chi-square tests, and statistical significance was defined as p<0.05. RESULTS: The incidence of PIH was 7.1% of total deliveries. Among the PIH, the incidence of mild preedampsia was found in 59%, severe preeclampsia in 36%, and edampsia in 5%. The most prevalent gestational period was 38-42wks gestation in mild PIH and 33-37wks gestation in severe PIH & eclampsia. The incidence of cesarean section was significantly higher in severe PIH & eclampsia(72.2%) than in mild PIH(48.7%) and normotensive pregnancies(39.7%). The incidence of hypoalbuminemia, preterm labor, placental abruption, disseminated intravascular coagulation, and pulmonary edema were significantly higher in severe PIH & edampsia than in mild PIH and normotensive pregnancies. Compared with normotensive pregnancies or mild PIH, severe PIH & eclampsia had significantly elevated risks for low birth weight, intrauterine growth retardation, fetal distress, low apgar score, meconium stained, and neonatal deaths. CONCLUSION: The incidence of PIH is not decreasing and it still an important role in the cause of maternal and perinatal mortality and morbidity in Korea. So, further studies are necessary to prepare a guide for the treatment of PIH.
