Little objective information is avilable on the influence of occlusive dressings on the healing of cutaneous partial skin defect wounds. Our purpose was to examine the effects of occlusive dressing by using the synthetic dressing mateial, PolyMem in the management of 2nd degree burn wounds and donor sites of split thicknes skin graft and partial-thickness wounds in rabbits. New Zealand white rabbits, 12 to 14 weeks of age, were divided into 2 groups. Two partial thickness skin wounds measuring approximately 40x30 mm were induced using a scalpel on the back of each anesthetized animal. They were designated as group I (dressing with conventional method, n=15), group II (dressing with PolyMen, n=15). Each treated wound was individually covered with the assigned dressing immediately after wounding. Wound were examined and measured at 10 days to determine the extent of healing. By day 10, the PolyMem dressed wounds were approximately 67% healed, while all vaseline gauze dressed wounds were about 50% healed. Standardized 20 mm full-thickness biopsy wounds were treated for 10 days. Section of PolyMem group at POD 10 days showed complete epidermal regeneration above fibrotic dermis (H&E, x40). Section of conventional group at POD 10 days showed marginal epidermal regeneration (H&E, x40). 72 patients (44 patients with 2nd degree burn and 28 patients with skin graft donor sites) were divided into four groups. They were designated as group I (Burn patients with PolyMem, n=24), group II (Burn patients with conventional methods, n=24), group III (S.T.S.G. patients with PolyMem, n=14), group IV (S.T.S.G. patients with conventional methods, n=14). We investigated wound site pain, healing time, comfort and numbers of dressing change. As compared with the control group, the PolyMem dressed group had less pain, more rapid healing time, more comfort, less frequent dressing changes. From these results, we concluded that the occlusive dressing with PolyMem was an effective alternative to the conventional gauze dressig on the wound healing. Our results suggest tat PolyMem is one of the ideal dressing materials.

We report 2 cases of pediatric DNTs which presented with intractable seizures and no other associated neurologic abnormalities. They showed typical appearance of DNTs on neuroimaging and histopathology. Most patients with DNT can be cured by surgical treatment with exellent outcome and do not need ratio- or chemotheraphy. This study indicates that it is quite important to consider DNTs as one of differential diagnoses in patients with intractable seizures especially when they present only with seizures without other neurologic symptoms.

Paragonimiasis is prevalent in Far East and a kind of endemic Korean disases. The primary site of humanparagonimiasis is the lung, but hte ectopic infection of lung fluke has been reported by many authors. Weexperienced one case of abdominal paragonimiasis in a 44 year old male with a complaint of left lowerquadrantpain. Physical examination, barium enema, and other data suggested the possibility of tumor originating from thewall of descending colon. (intramural tumor). Postoperative specimen taken from the solid tumorous lesion showedparasitic granuloma, characteristic of Paragonimus Westermani. Here, we report a case of very peculiar ectopicparagonimaisis involved descending colon wall simulating neoplastic tumor, and also review the literaturesbriefly.

OBJECTIVE: The purpose of this study was to determine the important factors affecting survival and pregnancy rate in frozen-thawed embryo transfer cycles. METHODS: we performed reprospective analysis in 738 cycles of frozen-thawed embryo transfers, in relation to the insemination methods, the freezing stage of embryo, patient's age, infertility factors and the origin of injected sperm in ICSI cycles. After conventional IVF or ICSI, the supernumerary PN stage zygotes or multicellular embryos were cryopreserved by slow freezing protocol with 1,2-propandiol (PROH) as a cryoprotectant. RESULTS: The survival rates of thawed embryos were 69.3% (1585/2287) in conventional IVF group and 71.7&% (1645/2295) in ICSI group. After frozen-thawed embryo transfers, 27.0% (92/341) and 32.0% (109/341) of pregnancy rates were achieved in conventional IVF and ICSI group, respectively. There were no significant difference in the survival and pregnancy rates according to the insemination methods, the freezing stage and patient's age. However, the pregnancy rate (36.2%) of male factor infertility (22.9%). In ICSI group, the origin of injected sperm did not affect the outcome of frozen-thawed embryo transfer cycles. CONCLUSION: The present study demonstrates that acceptable clinical outcomes can be achieved after the transfer of frozen-thawed embryos regardless of the stage of embryos for freezing, the patient's age and the origin of injected sperm.

BACKGROUND: Adolescent girls are interested in weight reduction, but effective and adequate education for weight reduction is not done in Korea. And so much information is accepted via mass media. We investigated body image perception, weight control activities and their side effects among adolescent girls. METHODS: We used questionnaire about body image and weight control activities of middle and high school girls in Seoul in Sep. 1995. RESULTS: 88.6% of girls were not satisfied with their own height and 85.1% of girls with their own weight. 66.3% underweight students(BMI<20kg/m2) thought they were too fat and 98% acceptable weight students(20kg/m2<_KBMI<25kg/m2) thought they were too fat. So most girls had body image disturbance. 42.4% of girls were trying to lose weight and 85.1% were trying to lose weight reason for attractiveness and 16.6% were trying to lose for health. Self reported weight reduction methods were exercise(31.6%), fasting(21.9%), diet(21.5%), monodiet(10.8 %), laxatives(2.3%), very low calorie diet(1.8%) etc. Students who tr ied to lose weight for attractiveness selected more undesirable methods than who tried to lose weight for health(P<0.01). Most common route is via magazine, TV and newspaper. 43.4% of girls who tried to lose weight experienced side effects after weight reduction, those were dizziness(71.3%), general weakness(51%), apathy(26.S%) etc. CONCLUSIONS: Most girls had body image distortions. Useless weight reduction activities were done or planned and most of information was accepted via mass media. It is important to educate the girls to get adequate body image and effective weight reduction program is needed for health in adolescent girls.

We evaluated the accuracy of a noninvasive method for estimating right ventricular systolic pressures in patients with atrial septal defect and tricuspid regurgitation defected by two-dimensional and Doppler ultrasound. Of 54 patients with atrial septal defect, 24(44%) had jets of tricuspid regurgitation. By use of the maximum velocity(V) of the regurgitatant jet recorded by continuous wave Doppler ultrasound and the Bernoulli equation, we predicted right ventricular systolic pressure(RVP) calculated by the equation of RVP=4V2+10 proposed by Tei et al.The values correlated well with catheterization values(r=0.851, standerd error of estimate=4mmHg). In addition the relation between the Lt to Rt shunt amount and the severity of tricuspid regurgitation was assessed. The severity of tricuspid regurgitation graded on a four-pointscali by pulsed Doppler and two-dimensional echocardiography correlated with Qp/Qs ratio calculated by the Fick's method(p<0.05).

PURPOSE: This study was done to identify menstrual discomfort and dietary habits, and factors related to the menstrual discomforts. METHOD: Participants were 320 female middle school students in G city. The Menstrual Discomfort Questionaire(MDQ) and dietary habit lists were used as tools. RESULTS: Factors related to MDQ were found to be the VAS scores (r=.361, p=.002), a mount of menstrual bleeding (r=.131, p=.019), height (r=.134, p=.016), adequacy of meal time (t=7.19, p=.008), consumption of milk & milk products (F=3.20, p=.042) and, hot, salty & irritant foods (F=8.01, p=.000), eating more than 3 kinds of side-dishes with each meal (F=8.32, p=.000), and various protein foods (F=5.15, p=.006). In stepwise regression, 4 variables (VAS scores, height, hot, salty & irritant foods, more than 3 kinds of side-dishes with each meal) explained 20.3% of the variance in the total MDQ scores. CONCLUSION: Reduction of hot, salty & irritant foods and having more than 3 side-dishes with each meal would be effective in menstrual discomfort management. As well, good and, balanced dietary habits should be encouraged for early adolescent girls. To keep up with the ideal dietary habits, nutritional education & counseling should be continued. In a further study, a replication study with larger samples and more specified nutritional assessment are recommended.

PURPOSE: This survey was done to describe parenting self-efficacy and beliefs in corporal punishment as they are related to child abuse. Also demographic variables that influence child abuse were investigated. METHOD: A cross-sectional study was conducted during the second week of April 2002. The 160 participants were parents of students in five elementary schools in the J area of Korea. They replied to a structured questionnaire, and 129 replies were included in the final analysis. The WIN SPSS program was used for the analysis. RESULT: Parenting self-efficacy, beliefs in corporal punishment and child abuse showed no significant differences according to gender of the children. Child abuse by parents has significantly negative correlation with parenting self-efficacy (r=-.369, p=.000), socioeconomic states of family(r=-.290, p=.001), educational level of mother(r=-.211, p=.027), educational level of father(r=-.342, p=.000), parent's age(r=-.200, p=.028). Stepwise multiple regression showed that parenting self-efficacy and beliefs in corporal punishment significantly influence child abuse in Korean parents. CONCLUSION: As parenting self-efficacy explained 49.7% of child abuse, it is the most important variable for preventing child abuse. Belief in corporal punishment was the second most important variable in preventing child abuse. These two variables explained 53.3% of variance in child abuse by parents.
