To estimate the prevalence and trend of obesity in primary school-age children, obesity survey was performend in children aged 6 to 12 years(5,226 boys and 5,048 girls)in Kwangju in 1991. Obesity was defined as overweight if more than 20 per cent above the median weight for height and age(relative weight>120%). The following results were obtained: 1) The prevalence of obesity that exceeded the weight centiles at each height by more than 97th percentile was 8.78. Boys (9.70%)was not significantly higher than in girls(7.82%)(p>0.05). 2) The prevalence of obesity that exceeded the standard weight for height by more than 20% was 8.82%. Among them, 5.45% were mild obesity and 2.93% were moderate obesity and 0.44% were severe obesity. The prevalence rate of obesity was no significant differences by sex(p>0.05). 3) Regionally, the prevalence of obesity was a lower rate in Kwangiu in 1991 (8.82%)than that in Seoul in 1989(11.68%).

The clinical, gross, light microscopic and immunohistochemical findings of three cases of blue nevus of the uterine endocervix were described. All three cases were incidentally found in hysterectomy specimens from middle-aged women, 45 to 48 years of age. The lesions were small and measured 1 to 4 mm in the greatest diameter. The presence of elongated, somewhat wavy and dendritic melanin-containing cells, in clusters or scattered deep in the subepithelial stroma and between the endocervical glands, was the distinct feature. The cytoplasmic granules appeared black with Grimelius and Fontana-Masson stains. The cells showed strong positive reaction with S-100 protein in perinuclear cytoplasm, in addition to the diffusely dispersed melanin granules. The demonstration of S-100 protein in the blue nevus, along with the histochemical findings, supports combined melanocytic and schwannian differentiation of the blue nevus cells.

Meningioma of unusual age of onset, location, histogenesis and histologic type is reported. The patient, 4 year-old girl, had an intradural spinal meningioma arising from lumbar nerve root with no dural attachement. The meningioma revealed glycogen-rich, clear cell type with extensive and blocky hyalinization of the stroma. The tumor shared common fibrous sheath with attached lumbar nerve, and nerve fibers were scattered within the tumor. Ultrastructurally, the tumor cells had abundant glycogen particles, intermediate filaments and intercellular desmosomes. Hyalinized material revealed large amianthoid collagen fibers.

Cytologic findings of malignant cells obtained by fine needle aspiration from a huge retroperitoneal malignant fibrous histiocytoma were described. The smears contained numerous malignant cells, isolated or in clusters, in a bloody background. The malignant cells had abundant pleomorphic foamy or acidophilic cytoplasm with occasional multilobated vesicular nuclei and prominent nucleoli. Dual differentiation, both histiocytic and fibroblastic types, and neutrophilic inflammatory background were diagnostic of this neoplasm. The report indicated that study of aspiration cytology specimen from a soft tissue tumor was a valuable adjunct to histologic examination.

A new balloon dissector, a modification of a Foley catheter, was devised and it can be used either as a dissector or a tissue expander. Since most operating time was spent in balloon manipulation (inflation/deflation), the duct for saline injection was made to be wider than the Foley catheter. As a result, the balloon could be inflated faster than before. In order to reduce the scar at the donor site, harvest of the sural nerve using endoscopic technique is currently applied, but utilization of this method is technically difficult and requires a long operating time. For these reasons, new our method of using a balloon dissector was devised. The balloon dissector can also be used for immediate intraoperative tissue expansion for the reconstruction of small skin defects without distortion. We have found that the advantages of using the new balloon dissector include a reduction in operating time, preservation of the perforating vessels, and primary closure with less tension. In addition, this simple and inexpensive instrument is cost-beneficial to patients.

Ninety black C 57 BL mice were divided into control and photochemotherapy groups. Control group was subdivided into a UVA 1rradiation only subgroup and a khellin only administration subgroup, while the phototherapy group was subdivided into one TMP and two khellin administration subgroups with dosages of 1.5mg/kg, 5mg/kg and 20mg/kg, respectivly. UVA was administered three thimes a week in a dose of 4J/cm for 4 weeks. Skin biopsies were taken at 0, l, 2, 3 and 4 weeks and the split DOPA stain was employed to observe pigment production. The number, size and circumference of the melanocytes were assessed. In summary, our results inclicate that khellin, which is slightly less effective than TMP at the same effective dose, is quite effective for pigment production and the degree of the production is dose related.

Postcholecystectomy syndrome is the persistence or recurrence of symytom complex following cholecystectomy, The majority of the patients have mild symptoms. However, the cause of recurrent symptoms is often obscure and as a consequence, a plan of management is difficult to formulate. Recently ERCP has proved to be increasingly helpful in the investigation of postcholecystectomy patients. The purpose of this study was to test the effectiveness of the ERCP in the evaluation of patients with postcbiolecystectomy syndrorae. The results are as follows 1) 102 postcholecystectomy patients were studied by endoscopic retrograde cholangiopancreatography and successful cannulation with demonstration of at least one duct was achieved in 49 of 50 jaundiced patients and in 49 of 52 non-jaundiced patients. The overall success rate was 96. 1%. 2) The results of ERCP were normal in 26 patients(26.5%) and abnormal in 72 patients (73.5%), Only 3 of 50 jaundiced patients were normal, but 23 of 52 non-jaundiced patients showed no abnormal findings. 3) The most common abnormality was biliary stone in common bile duct and intrahepatic duct which were present in 51 patients(50%). Cholangitis without stone was next common finding which was in 13 patients(13%). Of the remaining patients have air biligram, 2 CBD stricture, 1 CBD aseariasis & 1 chronic pancreatitis. 4) Time lapse between onset of symptoms and cholecystectomy was variable. 31 patients were studied less than 2 years after cholecystectomy. 18 of these patients had jaundice and 13 had no jaundice. Within 2 years afte chklecystectomy, the biliary stone was most common finding which were present in 14 out of 31 patients.

OBJECTIVE: Evaluation of embryos using early cleavage to 2-cell stage has been proposed, but a critical time-point for selecting embryos is unclear. The aim of the present study is to provide a guideline including critical time-point in the selection of early cleaving embryo for the reduction of multiple pregnancies as well as the increase of pregnancy rate in human IVF. METHODS: This prospective study was performed in 116 cycles from 85 patients who underwent conventional IVF or ICSI at the infertility clinic of Good Moonhwa Hospital from January 2002 to December 2003. Early cleavage (EC) of embryos to 2-cell stage was assessed at 25 h and 27 h postinsemination/microinjection. Embryos that had early cleaved at each time point were designated as EC-1 and EC-2, respectively, while others were designated as non-early cleavage (NEC). RESULTS: At least one early cleavage embryo was observed in 54 (46.6%) for the EC-1 and 84 (72.4%) for the EC-2 of the 116 cycles assessed. Clinical pregnancy rates (PR) were significantly higher in the EC-1 group (66.7%) compared to the EC-2 group (53.6%) or the NEC group (31.2%) (p<0.05). Significant improvement of the pregnancy rate was found when at least two or more embryos were early cleaved at 25 h postinsemination or when the proportion of early cleavage embryo at 25 h postinsemination was higher than 20% (p<0.05). CONCLUSIONS: The critical time-point for the selection of early cleavage embryos with high implantation potential is more effective in 25 h postinsemination/microinjection compared to 27 h. The proportion as well as number of early cleavage embryos is also an important factor for the prediction of pregnancy outcome and the chance of multiple pregnancies. These results demonstrated that the evaluation of early cleavage embryos to 2-cell stage is an easy, simple, and objective method for the selection of good quality embryos suitable for embryo transfer.
