Ovarian cysts in the newborn are uncormnon. Fetal ovarian cysts are being diagnosed with inaeasing fiequency with development of obstetrical sonography. Most of these cysts are found within the first few months of life and have no clinical significance. But, a large ovarian cyst would be founded antenatally with sonography. A large ovarian cyst can cause life-theatening complications during parturition and in the neonatal period. We have experienced a case of fetal ovarian cyst in a 32-year-old primiparous woman with antenatal sonography and report our experience with a brief review of literatures.

A prospective study was initiated to compare maternal serum concentration of CA-125 during the first trimester of normal and abnormal pregnancies. Serum specimens were obtained from 87 women with a normal intrauterine pregnancy and 47 women with abnormal pregnancies which were ended in spontaneo abortion or pathologically confirmed to be missed abortion. In normal pregnancies, the mean serum CA-125 concentrations were increased significantly from amenorhea 6 weeks (139.838.7 IU/ml), and were higher statistically than the values tested in the same weeks of abnormal pregnancies. In abnormal pregnancies serum CA-125 concentations were relatively lower than those of normal pregnancies. But these differences were not statistically significant except the values tested in amenorhea 6weeks. So serum levels of CA-125 may not be proved useful in monitoring of early pregnancies outcome.

OBJECTIVE: To investigate the histologic features of the uterus and adnexae extirpated from gender identity disorder (GID) patients that received depot androgen injection. METHODS: We reviewed the histologic findings of the uterus and adnexae removed from sixteen GID patients, who had taken depot androgen injection for 5~168 months. RESULTS: Fourteen patients (87.5%) showed the atrophied epithelium of exocervix and all of 16 patients (100%) showed the atrophy of endometrium. Seven patients (43.7%) showed multiple cystic follicles in the ovarian cortex and 6 patients (37.5%), 3 patients (18.7%) showed corpus albicans and corpus luteum, respectively. CONCLUSIONS: Exogenous androgen induced atrophy of cervix and endometrium. This effect was more prominent in the endometrium. In addition, PCO-like histologic features were observed in the ovary.

Endothelins secreted from keratinocytes are intrinsic mitogens and melanogens of human melanocytes in UVB-induced hyperpigmentation. To elucidate the cellular mechanism of antimelanogenic activity of bamboo extract, the effects of three ingredients of bamboo extract on endothelin 1 (ET-1) -induced Ca2+ mobilization were investigated in cultured human melanocytes. ET-1 receptors in human melanocytes were characterized by using specific antagonist, and ET-1 was found to increase intracellular Ca2+ concentration ([Ca2+]i) by activating ET-B receptor. SM709 (1, 2-O-diferulyl-glycerol), an ingredient of bamboo extract, inhibited ET-1-induced [Ca2+]i increase in a concentration- and time-dependent manner, although another ingredients SM707 and SM708 had no effect on ET-1-induced [Ca2+]i increase in human melanocytes. SM709 (100 microM), however, did not affect [Ca2+]i increase induced by thapsigargin and caffeine, suggesting that SM709 has no effect on the Ca2+ store in melanocytes. Furthermore, SM709 did not affect [Ca2+]i increase induced by LPA or ATP, known as G protein-mediated PLC activators like ET-1. Taken together, it is suggested that SM709 antagonizes ET-1-induced transmembrane signaling through ET-B receptor, which maybe a possible underlying mechanism of antimelanogenic activity of bamboo extract in human melanocytes.

OBJECTIVE: The selection of dialysis modalities for end-stage renal disease patient is often a complex decision process involving considerations of efficacy in terms of life maintenance, quality of life, convenience and cost. In order to facilitate informed decisions, we have compared the clinical outcome of CAPD and HD patients. METHODS: From May 1992 to May 1997, we observed the followings: patients` survival rate, the causes of death in CAPD and HD patients, the frequency of CAPD peritonitis, CAPD catheter survival rate and the causes of catheter removal. Patients were categorized in the following ways: DM and non-DM, alive or expired, above and below the age of 60 years, and treatment duration of more or less than 5 years. Six items (serum albumin, serum creatinine, hemoglobin, BMI, NPCR and KT/V) were measured, their values were evaluated and compared with each group using univariated statistics. RESULTS: The total number of patients was 508 (369 CAPD, 139 HD). 58 of them expired during the observation period. The overall 5 year patient survival rate was 81.4% for CAPD, 80.5% for HD, and 57.8% for CAPD with DM and 25% for HD with DM using the Kaplan-Meier method. In the CAPD group, the frequency of peritonitis was 0.52 /pt, yr; the 5 year technical survival of the catheter was 80.5%. 42 (88%) of 48 technical failures of the catheter were removed due to peritonitis. Regardless of the modes of replacement therapy used to treat DM and non-DM groups, the DM patients had longer duration of admission, older age, lower serum albumin and serum creatinine levels , and a lower 5 year patient survival rate than the non-DM group. Death in CAPD and HD was positively correlated with a long duration of admission and old age; CAPD patients who expired had lower serum albumin, smaller BMI and more frequent peritonitis than the surviving group. CONCLUSION: 1. There was no significant difference in the 5 year patient survival rate between CAPD and HD (81.4% in CAPD, 80.5% in HD). 2. DM patients had lower serum albumin, creatinine and BUN levels than non-DM patients. 3. The mortality rate was positively correlated with old age and duration of admission in CAPD and HD ; frequent CAPD peritonitis, lower serum albumin and small BMI in CAPD were also positively correlated with the death rate. 4. The higher the serum albumin and NPCR, the higher the survival rate for CAPD patients. 5. The serum creatinine was lower in patients above 60 years old and in those treated more than 5 years. 6. The DM group had a higher mortality rate than the non-DM group; the DM CAPD group had a higher 5 year survival rate than the DM HD group but it was not statistically significant.

Occurence of lactic acidosis with adequate tissue oxygenation(type B lactic acidosis) has been described in association with leukemia, lymphoma, small cell carcinoma and breast cancer. However, no such case has been reported in Korea. Therefore, we report a case of type B lactic acidosis in a man with rapidly progressing acute lymphoblastic leukemia which had been transformed from lymphoma.

A new surgical approach to the area of the infratemporal fossa and parapharyngeal space is described. This approach results in a wide-field exposure of the infratemporal fossa, pterygomaxillary space and parapharyngeal space. We used two osteotomies on the patient's mandible and temporary resection of zygomatic arch for superior margin of tumor. Lower lip splitting was not needed because the incision was started in the frontal scalp, curved in front of and below the external auditary canal, and extended anteriorly to the greater horn of hyoid bone on the neck along a skin crease. We had good results without sacrifice of the facial nerve, mandibular function and sensory supply of the face and oral cavity.

PURPOSE: The adult tetanus, reduced diphtheria, and acellular pertussis (Tdap) vaccine has been introduced in order to provide individual protection and reduce the risk of transmitting pertussis to infants. We assessed the knowledge and acceptability of the Tdap vaccine around pregnancy. MATERIALS AND METHODS: This study was a cross-sectional survey of women of childbearing age (20-45 years) who visited obstetrics and gynecologic units of primary, secondary, or tertiary hospitals. They were asked to fill in a questionnaire assessing their knowledge, attitudes, and acceptability of Tdap. RESULTS: The questionnaire was completed by 308 women; 293 (95.1%) had not received information from doctors about Tdap, and 250 (81.2%) did not know about the need for vaccination. A significantly important factor related to subjects' intention to be vaccinated, identified by stepwise multiple logistic regression, was the knowledge (OR 13.5, CI 3.92-46.33) that adult Tdap is effective in preventing pertussis for infants aged 0-6 months. Additionally, 276 (89.6%) considered the recommendation of obstetric doctors as the most influencing factor about Tdap vaccination. CONCLUSION: In Korea, most women of childbearing age seem to be neither recommended nor adequately informed about the vaccination, although our population was not a nationwide representative sample. Information given by healthcare workers may be critical for improving awareness and preventing pertussis.

OBJECTIVES: To compare the effect of three different cryoprotectants on basic stem cell characteristics for the possibility of using well defined, dimethyl sulfoxide (DMSO) and serum free freezing solutions to cryopreserve human Wharton's jelly-derived mesenchymal stem cells (WJMSCs) following controlled rate freezing protocol. METHODS: The mesenchymal stem cells isolated from human Wharton's jelly were cryopreserved using 10% DMSO, 10% polyvinylpyrrolidone (PVP) and a cocktail solution comprising of 0.05 M glucose, 0.05 M sucrose and 1.5 M ethylene glycol following controlled rate freezing protocol. We investigated the post-thaw cell viability, morphology, proliferation capacity, basic stem cell characteristics, in vitro differentiation potential and apoptosis-related gene expression profile before and after cryopreservation. RESULTS: The cryoprotectant 10% DMSO has shown higher post-thaw cell viability of 81.2+/-0.58% whereas 10% PVP and cocktail solution have shown 62.87+/-0.35% and 72.2+/-0.23%, respectively at 0 h immediately thawing. The cell viability was further reduced in all the cryopreserved groups at 24 h later post-thaw culture. Further, the complete elimination of FBS in cryoprotectants has resulted in drastic reduction in cell viability. Cryopreservation did not alter the basic stem cell characteristics, plasticity and multipotency except proliferation rate. The expression of pro-apoptotic BAX and p53 genes were higher whilst p21 was lower in all the cryopreserved groups when compare to the control group of WJMSCs. CONCLUSION: Although 10% DMSO has shown higher post-thaw cell viability compare to 10% PVP and cocktail solution, the present study indicates the feasibility of developing a well-defined DMSO free cryosolution which can improve storage and future broad range applications of WJMSCs in regenerative medicine without losing their basic stem cell characteristics.

The increasing prevalence of Toxoplasma gondii infection in the human population in the Republic of Korea (= Korea) is due to various reasons such as an increase in meat consumption. However, the importance of cats in transmitting T. gondii infection through oocysts to humans has seldom been assessed. A total of 300 fecal samples of stray cats captured around Seoul from June to August 2013 were examined for T. gondii B1 gene (indicating the presence of oocysts) using nested-PCR. Fourteen (4.7%) of 300 cats examined were positive for B1 gene. Female cats (7.5%) showed a higher prevalence than male cats (1.4%). Cats younger than 3 months (5.5%) showed a higher prevalence than cats (1.5%) older than 3 months. For laboratory passage of the positive samples, the fecal suspension (0.2 ml) of B1 gene positive cats was orally inoculated into experimental mice. Brain tissues of the mice were obtained after 40 days and examined for the presence of tissue cysts. Two isolates were successfully passaged (designated KNIH-1 and KNIH-2) and were molecularly analyzed using the SAG5D and SAG5E gene sequences. The SAG5D and SAG5E gene sequences showed high homologies with the ME49 strain (less virulent strain). The results indicated the importance of stray cats in transmitting T. gondii to humans in Korea, as revealed by detection of B1 gene in fecal samples. T. gondii isolates from cats were successfully passaged in the laboratory for the first time in Korea.
