1.Flow Cytometric DNA Content Analysis in uterine Cervical Cancer.
Korean Journal of Gynecologic Oncology and Colposcopy 1994;5(3):49-53
The DNA ploidy using fresh tissues from 304 cervial cancer were analyzed by flow cytometry in order to evaluate the correlation between DNA ploidy patterns and prognostic factors of uterine cervical cancer. There were l67 diploid cases(55%) and 137 aneuploid(45%). No significant correlation was noted in stage, age and lymph node metastases between diploid and aneuploid tumor. But S-phase fraction and DNA index were higher slightly in cases of lymph node metastases cornpaired to non-metastases. This results suggest that the DNA ploidy cannot be used as an independent prognostic fac- tor, but further evaluation will be needed in order to conclude definite relationship between prognoseic factor and S-phase fraction or DNA index.

PURPOSE: We conducted this research to make an earlier diagnosis and identify better treatment for Kikuchi-Fujimoto disease (KFD) by comparing clinical findings with nonspecifically enlarged cervical lymph nodes in children. METHODS: Nineteen patients were diagnosed with KFD by tissue pathology from a fine needle aspiration biopsy and/or excisional biopsy and were compared with the clinical, radiological, and pathological findings of reactive hyperplasia. RESULTS: The average onset age of onset for patients with KFD was 11.8+/-3.61 years, and the male to female ratio was 1:1.1, whereas patients with reactive hyperplasia were 11.8+/-5.96 years, and the male to female ratio was 1.7:1. Patients with KFD suffered more from fever than patients with reactive hyperplasia (68% vs. 13%, P=0.002). Patients with KFD showed perinodal infiltration (P=0.001) and necrosis on computed tomography, whereas patients with reactive hyperplasia did not show any of these findings. Ultrasonographic findings were similar between the two study groups. In contrast, the histopathological examinations of biopsied cervical lymph nodes were enormously helpful for distinguishing the findings of KFD from those of patients with reactive hyperplasia. CONCLUSION: We recommend a histopathological examination to distinguish KFD from reactive hyperplasia in children with significantly enlarged cervical lymph nodes.

The purpose of this study was to investigate and examine the relationship between dietary habits, food intake patterns, and depression in Korean women with polycystic ovary syndrome (PCOS). The Center for Epidemiologic Studies Depression Scale Korean Version was used to determine whether a participant was depressed or not. The dietary habits were assessed by the Min-Dietary Assessment (MDA) method, and food intake data were collected by the 24-hour recall method on two non-consecutive days, at least 7 days apart, and the average of the two days was used to estimate the usual dietary intake. The total MDA scores of the Depression Group was significantly lower than that of the No-Depression Group (31.5 +/- 6.4 vs 33.4 +/- 6.0, p = 0.027). The intake of cereals/potatoes/sugar products, milk and milk products, plant protein, and calcium for the Depression Group were significantly lower compared to the No-Depression Group. The Depression Group had a significantly higher percentage of energy intakes from protein as well as the consumption of fish and shellfish compared to the No-Depression Group. There was a significant inverse relationship between milk and milk products consumption and the prevalence of depression [OR (95% CI) for the highest tertile compared to the lowest: 0.390 (0.177-0.857); p for trend = 0.016]. There were also significant positive relationships between the prevalence of depression and the consumption of the following: fish and shellfish [OR (95% CI) for the highest tertile compared to the lowest: 2.319 (1.128-4.770); p for trend = 0.009], animal protein (p for trend = 0.049), and the percentage of energy intakes from protein [OR (95% CI) for the highest tertile compared with the lowest: 2.546(1.156-5.609); p for trend = 0.025]. Further studies are needed in order to investigate whether the intake of protein and of animal protein is indeed associated with depression in PCOS patients in Korea and the possible mechanisms thereof. The results of our study can be applicable for the development of effective nutrition counseling and education programs regarding PCOS patients with depression as part of their successful treatment regimen.

PURPOSE: There are a number of reports suggesting that widespread propagation of weeds and high concentration of weed pollen have been contributed to climate change. We investigated the interrelationship between allergenic pollen concentration, allergic symptom and meteorological factor. METHODS: We collected data of pollen concentration and meteorological factors in 7 stations nationwide during between 1998 and 2012. We recruited total 297 allergic patients sensitized to weed pollens from each station, conducted a survey about allergic symptom, and calculated symptom index. We surveyed the vegetation area of ragweed and Japanese hop. Based on these data, we performed the long-term trend analysis (X11-ARIMA, autoregressive integrated moving average) on regional pollen concentration, and correlation analysis to investigate the interrelation between weed pollen concentration, allery symptom index and meteorological factor. We have also done regression analysis on vegetation area and maximal pollen concentration. RESULTS: Long-term trend analysis showed the increasing trend of pllen concentration in Seoul. Weed pollen concentration, allergy symptom index and each meteorological factor were not correlated significantly. Regression analysis revealed that increase of weed vegetation area results in increase of weed pollen concentration. Through this regression equation, we estimated the vegetation area that can product pollen concentration triggering allergenic risk. CONCLUSION: Meteorological factors, pollen concentration and allergic symptoms should be consistently assessed and the relationship between each factor should be analyzed, considering climate change. It is necessary to verify the equation for pollen estimation by vegetation area and set up a policy for vegetation control focused on the reduction of allergenic pollen.

BACKGROUND/AIMS: In order to identify microsatellite instability (MSI), the test based on the polymerase chain reaction (PCR) can be used. However, PCR is not routinely performed in all hospital laboratories. Recently, immunohistochemistry (IHC) for MLH1 and MSH2 proteins has been reported as a rapid and useful method for MSI. However, the efficacy of IHC in the detection of the MSI has not been well established. The aim of this study was to evaluate the usefulness of IHC in the detection of the MSI by comparing it with the test results using PCR in colorectal cancer (CRC). METHODS: Paraffin-embedded normal and tumor tissues from seventy-five patients who underwent surgical resection of CRC were used. Abnormal expression of MLH1 and MSH2 protein was determined by IHC using MLH1 and MSH2 antibodies. Normal and tumor DNAs were obtained from thirty CRC tissues that showed abnormal expression of MLH1 and MSH2 proteins by IHC. The MSI status was confirmed by PCR using five markers. RESULTS: Thirty tumors showed abnormal expression of MLH1 and MSH2 proteins by IHC, but only three tumors out of them were confirmed to have MSI by PCR. CONCLUSIONS: This result suggests that IHC with MLH1 and MSH2 antibodies does not seem to be a useful method to identify MSI in CRC, therefore PCR is required for detection of the MSI.

Sibutramine is an anorectic that has been banned since 2010 due to cardiovascular safety issues. However, counterfeit drugs or slimming products that include sibutramine are still available in the market. It has been reported that illegal sibutramine-contained pharmaceutical products induce cardiovascular crisis. However, the mechanism underlying sibutramine-induced cardiovascular adverse effect has not been fully evaluated yet. In this study, we performed cardiovascular safety pharmacology studies of sibutramine systemically using by hERG channel inhibition, action potential duration, and telemetry assays. Sibutramine inhibited hERG channel current of HEK293 cells with an IC50 of 3.92 muM in patch clamp assay and increased the heart rate and blood pressure (76 Deltabpm in heart rate and 51 DeltammHg in blood pressure) in beagle dogs at a dose of 30 mg/kg (per oral), while it shortened action potential duration (at 10 muM and 30 muM, resulted in 15% and 29% decreases in APD50, and 9% and 17% decreases in APD90, respectively) in the Purkinje fibers of rabbits and had no effects on the QTc interval in beagle dogs. These results suggest that sibutramine has a considerable adverse effect on the cardiovascular system and may contribute to accurate drug safety regulation.
