1.A Study on the Heavy Metal Contents in Freshwater Fishes of the Mankyung River.
Korean Journal of Preventive Medicine 1988;21(1):121-131
This study was performed to investigate the heavy metal contents of freshwater fishes. The samples of 24 species were collected at 7 areas located on the Mankyung River during September in 1987. And then the contents of lead, cadmium, copper and zine were analyzed by atomic absorption spectrophotometer. The results were summarized as follows ; 1. The mean value of lead, cadmium, and copper contents of fishes collected in the downstream were significantly higher than those of upstream. 2. The mean lead content of C. auratus was the highest 1.50+/-0.98 microgram/g in viscera and statistically significant difference from muscle content. 3. The mean cadmium content of C. auratus was the highest 0.087+/-0.054 microgram/g and significantly higher than that of muscle, skeleton and gill. 4. In the copper contents, the viscera of C. auratus was the highest 5.25+/-0.94 microgram/g and significantly higher than that of muscle, skeleton and gill. 5. The mean value of zinc content of C. auratus was shown the order of gill, skeleton, viscera and muscle.

2.Insulin Resistance and Lipid Profiles in Obese Children.
Journal of Korean Society of Pediatric Endocrinology 2004;9(1):50-58
PURPOSE:Obesity is associated with complications such as unfavorable lipid profiles, hyperinsulinemia, and hypertension. We investigated the degree of obesity, especially defined as BMI and the percentage of overweight for the standard weight (%Wt) on plasma lipid levels and insulin resistance in the pediatric age group. METHODS:In this cross sectional study, 64 children and adolescents were included. Anthropometric data including body weight, height, BMI, %Wt, fat percentage of body weight (Fat%), and waist to hip ratio (WHR) were collected. For metabolic data, 14 hour fasting serum glucose, insulin and lipid profiles were measured and index for insulin resistance (HOMA-IR, FGIR) were calculated. We analyzed if there exist relationship between each anthropometric data and metabolic data. Gender differences were also assessed. RESULTS:Hyperinsulinemia showed high prevalence in obese children (total=21.9%, male=22.5%, female= 20.8%). HOMA-IR correlated with BMI and %Wt (BMI:r=0.308, P<0.05; %Wt:r=0.414, P<0.05). FGIR also correlated with BMI and %Wt (BMI:r=-0.406, P<0.05; %Wt:r=-0.437, P<0.05). Fasting serum triglyceride levels showed statistically significant correlation with BMI and %Wt [Boys (BMI:r=0.334, P<0.05; %Wt: r=0.487, P<0.05), Girls (BMI:r=0.482, P<0.05; %Wt:0.406, P<0.05)]. CONCLUSION: BMI and %Wt were valuable for predicting insulin resistance and triglyceride level. Sexual dimorphism related to insulin resistance and dyslipidemia in obese children was not certain in this study.

The Journal of the Korean Orthopaedic Association 1998;33(4):1092-1097
We reviewed twelve cases of congenital dislocation of the knee(CDK) which treated at Keimyung University from January 1992 to January 1997. All case were type II dislocation according to classification suggested by Ferris and reduced with minimal treatment. Dislocation were reduced within 4 days in minimum after treatment and 3 weeks in maximum. The period of follow up ranged from 6 months to 5 years. Clinical results were good. Early diagnosis followed by conservative treatment is important and enough to treatment of the type II congenital dislocation of the knee.

BACKGROUND: Numerous studies demonstrated that genistein induced the decrease of proliferation and apoptosis in a variety of cells. However, there is no report about the effect of genistein on proliferation and demise of mast cells. OBJECTIVE: This study was conducted to investigate genistein-induced aoptosis of mast cells as it pertains to both its basic drug mechanism and the potential therapeutics of the pathologic conditions accompanying mast cell proliferation. METHODS: p815 murine mastcytoma cell line was used to assess the effects of genistein treatment including viability and proliferation, morphlolgic study, DNA electrophoresis, the effect of caspase inhibitor, western blotting, and mitochondrial event. RESULTS: Genistein indeced many apoptotic manifestations as evidenced by changes in cell morphology, generation of DNA fragmentation, activation of caspase 3, and DNA hypoploidy. The reduction of mitochondrial membrae potential and the release of cytochrome c to cytosol were also demonstrated. However, reduction of mitochondrial membrane potential and cytochrome c release were not prevented by caspase inhibitors zVAD-fmk and BocD.fmk, or PTP(permeability transition pore) blockers such as bongkrekic acid and cyclosporin A. CONCLUSIONS: This in vitro study suggests that pathologic increases in mast cell number possibly be regulated in vivo by therapeutic strategy enhancing apoptosis by treatment of genistein.

Journal of the Korean Society of Plastic and Reconstructive Surgeons 1999;26(5):968-975
Distal foot defect is frequently encountered as an output site in high-tension electrical burn injuries, and proper treatment methods should be applied in order to achieve a properly-functioning foot. However, in distal foot defects around the metatarsal heads or metatarsophalangeal joints, conventional methods have not been ideal, replaced by such methods as secondary healing, amputation or skin graft because there was insufficient tissue in the distal foot and the general condition of the patient was unsuitable for distant or free flap surgeries. So, in order to establish convenient, promising methods for the reconstruction of distal foot defects in severe electrical burns, we classified the distal foot into four zones according to their blood supply and we defined or created ideal reverse flaps in each zone. From April 1996 to March 1999, we reconstructed 43 cases of distal foot defects in fourth-degree high voltage electrical burn wounds. In 19 cases of MP(medial plantar) zone injuries, we used reverse medial plantar island flap and in 5 cases of DP(dorsalis pedis) zone, we created a reverse dorsalis pedis island fascia flap, In 11 cases of P(peroneal) zone, we created reverse peroneal fascia flap and in 8 cases of I (intermediate) zone, we modified a reverse posterior tibial island flap, There was partial flap necrosis or grafted skin loss in five cases, but those were extremely minor problems and we successfully reconstructed distal foot defects in all 43 cases. In conclusion, proper reverse flaps according to the zone of the distal foot are ideal reconstructive methods because they provide good vascularization, sufficient tissue from the proximal parts and they require short operative time with relatively easy procedures.

Korean Journal of Physical Anthropology 1994;7(1):9-23
The characteristics of craniofacial complex mere different from each individual, based on age, sex, size, race and environmental factors. This study was undertaken to find out the sexual and racial difference of the craniofacial complex using lateral cephalometrics and previous studies. The material of this study was lateral cephalometric radiograms, obtained from 100 Korean adults (50 males and 50 females) ranged 20 to 27 years old, who have normal occlusion and pleasing profile. The results obtained from this study there as follows : 1. The mean values in the craniofacial complex of some Korean adults pith normal occlusion mere established. 2. The maxillae of female subjects there more protrusive than those of males. 3. In size the craniofacial complex, the male subjects were greater than females. 4. In position of upper and lower incisors, the male subjects there more protrusive than females. 5. In ratios between anterior and posterior facial height, the male subjects mere higher than females. 6. The upper incisors of some Korean adults mere relatively more protrusive than those of the other ethnic groups.

9.A Comparison of UVB-induced Minimal Erythema Dose ( MED ) s to the Skin of the Back and Extremities in Young Adult Koreans.
Korean Journal of Dermatology 1998;36(2):261-265
BACKGROUND: The erythemal response of the skin to UVB radiation is used as a diagnostic phototest and guideline to phototherapy. OBJECTIVE: The purpose of this study was to compare the UVB-induced MEDs to the back, arm, and thigh skin METHODS: A sunlight fluorescenct lamp(Waldmann UV 7001K) was used as a UVB radiation source. The back, arm, and thigh skin were irradiated with the dose, from 40mJ/cm2 to 180mJ/cm2. The minimal doses for erythema responses to the skin were assessed visually at 24 hours after irradiation. RESULTS: MEDs of the back, arm and thigh skin were 92.6 +/- 17.3mJ/cm2(mean +/- S.D.), 123.0 +/- 24.2mJ/cm2, and 126.6+/- 28.3mJ/cm2, respectively. The most frequent MED was 100mJ/cm2 for the back skin and 120mJ/cm' for the arm skin and thigh skin. CONCLUSION: In this study, UVB-induced MEDs to the back, arm, and thigh skin in young adult Koreans were assessed. A significant difference in the MED was found between the back and extremities skin, with a lower value for the back skin(92.6 +/- 17.3mJ/cm2) than for the arm skin(123.0 +/- 24.2mJ/cm2) or for the thigh skin(126.6 +/- 28.3mJ/cm2).
