Monitoring fetal movement serves as an indirect rneasure of fetal well-being, especially for central nervous system integrity and function. Methods to monitor fetal movement vary from the simple approach of having the mother chart perceived movement to highly specialized methods. However there were no reliable objective monitoring methods in Korea. For development of objective method for evaluating fetal movement, during pregnancy, one-hundred and two pregnant patients were entered to this study. All patients were divided into following 3 groups and each type of monitoring methods were applied. Group 1(N=20): Type I using portable FHR Doppler unit(IFD-100 model, Intermed, Korea). Group 2(N=20): Type II using FHR Microphone(Prenatal Listening Kit, Model FS002, Unisar Inc., US). Group 3(N=62): Type III using conventional ultrasound transducer(Corometric 115 Model, US). In this study, accurate counting of the fetal movementutus were best performed using Type III, because of monitoring fetal movements has its greatest efficiency when using conventional ultrasound transducer of fetal monitor. It was also attractive to doctors and nurses as a convenient methods because it needed only single transducer when compared to Type I and II. Although monitoring fetal body movement permits a general assessment of well-being, no perfect technique is still reliable. Futher techniques would be developed using the results of this study for improvement of several factors such as accuracy and objectiveness

The purpose of this study was to provide preliminary data for better safety control over children's preference foods sold in school stores. The survey was conducted from June to July 2009, to collect 749 types of children's preference foods sold in 150 middle and high school stores nation-wide excluding Jeju Island and general and nutrition information were analyzed. Out of 749 types of snack food items, 689 and 602 snacks were sold at high school and middle school stores respectively. Among children's preference foods, cookies, bread, and ice-cream were the main items. Among them, 98% of snacks were domestic products and the price range of each individual snacks were mostly between 600 and 900 won. 27.8% of children's preference foods sold were found to be in the high calorie/low nutrition food group. Even though the proportion of candy and fruit/vegetable beverages sold were not high, their proportion in high calorie/low nutrition snack group were higher than 68.1%. Among the children's preference foods sold in middleand high school stores, carbonated drinks and ramen were continuously sold in certain middle and high schools, even though sales were prohibited. This study concludes that government, corporations and retailers should work together in developing healthier children's snack distribution environment. In addition, dairy products, which take up 15% of children's preference food, should be diversified to meet their nutrient requirements.

BACKGROUND: It has long been suggested that neutrophils and their products are implicated as the central mediators of the acute lung injuries. Contrary to the dominant role of neutrophils in ARDS, many cases of ARDS has occurred in the setting of severe neutropenia without pufrnonary neutrophil infiltration. Therefore it is certain that effector cell(s) other than neutrophil play an important role in the pathogenesis of ARDS. This experiment was performed to define the mechanism of ARDS in the setting of neutiopenia, 1) by comparing the severity of endotoxin-induced lung injury, 2) by measurement of hydrogen peroxide production and cytokine concentration in the bronchoalveolar lavage cells and fluids obtained from different rats with and without cyclophosphamide-pretreatment. METHOD: The male Sprague-Dawleys were divided into the normal control (NC)-, endotoxin (ETX)-, and cyclophosphamide (CPA)-group in which neutropenia was induced by injecting cyclophosphamide intraperitoneally. Acute lung injury was evoked by injecting lipopolysaccharide (LPS) into a tail vein. The bronchoalveolar lavage (BAL) was performed at 3 and 6 hour after administration of LPS to measure the change of cell counts and concentrations of protein and cytokines, tumor necrosis factor-alpha (TNF-alpha) and interleukin-6 (IL-6). Hydrogen peroxide (HPO) production from BAL cel]s was measured at 6 hour after LPS administration by phenol red microassay with and without zymosan stimulation. RESULTS: The results were as follows. A change of leukocyte counts in the peripheral blood after treatment with CPA More than 95% of total leukocytes and neutrophils were reduced after CPA administration, resulting in severe neutropenia. A change of BAL cells In the ETX-group, the number of total cells (p<0.01) and of macrophage and neutrophll (p<0.05) were increased at 3 and 6 hour after LPS administration compared to those of NC- group. In the CPA-group, the number of total leukocyte and macrophage were not changed after LPS administration, but neutrophil counts were significantly reduced and jt took part in less than 0.1% of total BAL cells (p<0.01 vs NC-group). BAL cells in this group were almost all macrophages (99.7%). A change of protein concentration in the BALF In the ETX-group, protein concentration was increased at 3 hour and was more increased at 6 hour after LPS administration (p<0.05 and <0.01 vs NC-group, respectively). In the CPA-group, it was also significantly elevated at 3 hour after LPS administration (p<0.05 vs NC-group) , but the value was statistically not different from that of ETh-group. The value measured at 6 hour after LPS administration in the CPA-group became lower than that of ETX-group (p<0.05), but showed still a higher value compared to that of NC-group (p<0.05). A change of cytokine concentration in the BALF TNF-alpha and IL-6 were elevated in the ETX- and CPA-group compared to those of NC-group at both time intervals. There was no statistical difference in the values of both cytokines between the ETX- and CPA-groups. Measurement of hydrogen peroxide production from BAL cells There was no intergroup difference of HPO production from resting cells. HPO production after incubation with opsonized zymosan was significantly elevated in all groups. The percent increment of HPO production was highest in the ETX-group (89.0%, p<0.0008 vs NC-group ), and was 42.85 in the CPA-group (p = 0.003 vs NC-group ). Conclusion Acute lung injury in the setting of neutropenia might be caused by functional activation of resident alveola r macrophages.

OBJECTIVE: To determine whether cyclooxygenase (COX)-1 and COX-2 are expressed differentially during the whole gestational period in the pregnant human uterine cervix and if they are involved in the process of labor. METHODS: Nine patients were matched for obstetrical history and maternal age were divided into an abortion group who aborted between 13 and 16 weeks(n=3), a preterm group who delivered between 20 and 37 weeks(n=3), and a term group who delivered between 37 and 42 weeks of gestation(n=3). Immediately after vaginal delivery cervical biopsy samples were obtained and immunohistochemically stained for COX-1 and COX-2 and the degree of staining was evaluated by H-scoring system. RESULTS: Expression of COX-1 and COX-2 was found in epithelial and stromal cells of uterine cervical tissues of preterm and term group. The immunohistochemical expression of COX-1 and COX-2 was strongest in the term group compared to the preterm group in stromal cells(HSCORE : 2.0 vs. 4.0 ; 2.0 vs. 3.0), and in epithelial cells(HSCORE : 1.0 vs. 3.0 ; 1.0 vs. 3.0). CONCLUSION: Although small amount of the groups were investigated, in the pregnant human uterine cervix, COX-1 and COX-2 are found to be expressed, and both shows the strongest expression in term cervical tissue. It is suggested that the uterine cervix, under the control of prostaglandins, is actively involved in the process of labor, and it is thought that the role of COX-1 and COX-2 is more important in parturition process with advancing gestational age.

BACKGROUND AND OBJECTIVES: When a disability is superimposed on a previous disability, the concept of aggravation of disability should be applied. In rating the disability for hearing loss, we focused on the aggravation of disability and the methods of assessment. SUBJECTS AND METHOD: For the past 12 years, we have provided legal advisory for 111 cases of hearing injury, for which disability had to be rated. In 11 of those 111 cases, disability was assessed in consideration of aggravation of disability. We assessed disability using three rating methods: they were based on 1) a change of hearing level from assumed normal, 2) apportionment of new hearing injury in final hearing, and 3) a change in disability rating. We evaluated for significant differences and correlations between the values obtained by each method. RESULTS: There was a significant difference between the results by the methods 1 and 2. The disability rating by the method 2 showed good correlations with those assessed by the methods 1 and 3. CONCLUSION: When considering aggravation of disability in hearing, the method 2 could be a good alternative when the standard method 3 is inappropriate.

BACKGROUND/AIMS: Lamivudine is highly effective in suppressing hepatitis B virus replication and hepatitis B induced necroinflammatory activity. The objective of this study was to evaluate the virological and biochemical responses to lamivudine by patients with HBV associated chronic liver disease. In particular we stressed the importance of lamivudine therapy by patients with decompensated liver cirrhosis. METHODS: We conducted a one-year trial of lamivudine in 80 patients with HBV associated chronic liver disease (chronic hepatitis 44, cirrhosis 36). We classified these patients according to the severity of hepatic dysfunction as chronic B hepatitis (Group A) or liver cirrhosis (Group B). These patients were treated for 12 months with 100 mg daily doses of lamivudine. RESULTS: The seroconversion rate of HBeAg was 23.5% in group A patients and 26.7% in group B patients. The negative conversion of HBV-DNA was sustained for one year in 79.5% of patients in group A and 86.1% in group B. The normalization rates of serum ALT were 90.9% in group A and 88.9% in group B patients. No serious side effect after discontinuance of the treatment was found. There were 12 ALT breakthrough cases and all of them showed mutation of YMDD motif. However, they did not deteriorate clinically in spite of ALT elevation and HBV-DNA reappearance. The Child-Pugh scores improved even in patients with decompensated liver cirrhosis. CONCLUSION: One-year lamivudine treatment resulted in excellent virological and biochemical improvements and was well tolerated in the patients with HBV associated chronic liver disease, even in decompensated cirrhosis. We conclude that lamivudine is relatively safe in chronic hepatitis B and liver cirrhosis treatment.

OBJECTIVE: The objectives of this study were to obtain information on MIS levels in normal and RDS neonates and to investigate the relationship between the RDS prevalence and MIS level in preterm and term neonates. METHODS: Total 131 male neonates were selected randomly and they were consisted of 50 term normal neonates, 15 term neonates with RDS, 50 prematurely born normal neonates, and 16 prematurely born neonates with RDS. Total 131 female neonates were also selected like male neonates. The venous blood was collected from all subjects and measured the level of MIS using ELISA. The ANCOVA was conducted to evaluate any influence of adjusted value of gestational age and body weight on MIS level between normal neonates and neonates with RDS. RESULTS: 1) The MIS levels of female neonates were significantly lower than those of male neonates with no overlap. 2) The MIS levels of normal female neonates were not significantly different from those of female neonates with RDS. 3) There were significant negative relationships between MIS concentration and gestational age (r=-0.777, p<0.001), and birth weight(r=-0.728, p<0.001) in normal rnale neonates. 4) There were significant negative relationships between MIS concentration and gestational age (r=-0.726, p<0.001), and birth weight(r=-0.725, p<0.001) in male neonates with RDS. 5) After adjusting the value of gestational age, the MIS level of male neonates with RDS was significantly higher than that of normal male neonates(p<0.001). 6) After adjusting the value of body weight, the MIS level of male neonates with RDS was significantly higher than that of normal male neonates(p<0.001). CONCLUSION: Male neonates with RDS had higher MIS levels than normal male neonates of the same body weight or same calculated gestational age. The results of this study suggest that MIS may play a causative or important ancillary role in the sexual dimorphism that characterizes the neonatal RDS and may be used as a predictive marker of RDS in male neonates.
