Tardive dyskinesia(TD) is a serious side effect of long-term treatment with neuroleptic medications. To investigate if glutamatergic hyperfunction is associated with TD, effect of MK-801 on the prevention and treatment of TD was studied using a rat model, i.e., vacuous chewing movements(VCM). When comparing VCM scores of Group I(haldol decanoate+MK-801) with that of Group II(hadol decanoate+phosphate buffer saline), late measured VCM scores of former were significantly lower than that of latter, meaning that MK-801 is effective in the prevention of VCM. Furthermore, when MK-801 is also effective in the treatment of VCM. From the above results, it is suggested that glutamatergic hyperfunction might be involved in the development of TD and MK801 could be effective in the prevention and treatment of it.

Sertoli-Leydig cell tumors of the ovary are rare, accounting for no more than 0.5% of all ovarian neoplasms. These tumors occur predominantly in women 10 to 30 years of age. Heterologous elements are found in over 20% of the moderately and poorly differentiated Sertoli- Leydig cell tumors. The most common element is gastrointestinal mucin-secreting epithelium, found in approximately 20% of all cases. Approximately 4% of Sertoli-Leydig cell tumors contain immature skeletal muscle and/or cartilaginous elements. The origin of these neoplasms is regarded as neometaplasia of the mesodermal neoplastic element. While the degree of differentiation of Sertoli-Leydig cell tumors is probably of greater importance in determining prognosis than the presence of heterologous components, recent evidence does point to an unfavorable effect on clinical outcome when heterologous mesenchymal components such as cartilage and striated muscle are present. We experienced two cases of ovarian heterologous Sertoli-Leydig cell tumors with gastrointestinal type epithelium and striated skeletal muscle in 20 and 21 year-old females, respectively. One case involved a patient who had complained of amenorrhea for 3 years while the other case involved a patient who had complained of left lower abdominal tenderness and amenorrhea for one and one half years. It was determined by ultrasonography of the pelvis that the two patients suffered from right and left ovarian masses. Both patients underwent adnexectomy. These tumors were large with partly solid and partly cystic areas. Based on light microscopic examination one case was classified as an intermediate Sertoli-Leydig cell tumor with heterologous gastrointestinal type epithelium, while the other case was classified as a poorly differentiated Sertoli-Leydig cell tumor with heterologous striated skeletal muscle.

This study aims to examine the performance of public municipal hospitals through the analysis of data envelopment analysis, efficiency, profitability, and publicness by using panel data during period from 2006 to 2010. The main findings of the study are as follows. First, as a result of efficiency analysis during the period from 2006 to 2010, it was revealed that the number of staff by each job category, labor cost ratio, the number of operating beds need to be decreased. Second, the performance data represented by the indicators of efficiency, profitability and publicness were complementary and showed a tendency of being increased or decreased in same direction. Third, from the result of panel analysis, the efficiency was mainly influenced by the structural factors, while the profitability was influenced by managerial factors, and the publicness by medical environment. In conclusion, in order to enhance the performance of public municipal hospitals in Korea, it is important to harmonize the effort for efficiency, financial and policy support by central and local government, and the continuous participation of community residents.

BACKGROUND: This study aimed to investigate bradycardia as an adverse effect after administration of dexmedetomidine during 33degrees C target temperature management. METHODS: A retrospective study was conducted on patients who underwent 33degrees C target temperature management in the emergency department during a 49-month study period. We collected data including age, sex, weight, diagnosis, bradycardia occurrence, target temperature management duration, sedative drug, and several clinical and laboratory results. We conducted logistic regression for an analysis of factors associated with bradycardia. RESULTS: A total of 68 patients were selected. Among them, 39 (57.4%) showed bradycardia, and 56 (82.4%) were treated with dexmedetomidine. The odds ratio for bradycardia in the carbon monoxide poisoning group compared to the cardiac arrest group and in patients with higher body weight were 7.448 (95% confidence interval [CI] 1.834-30.244, p = 0.005) and 1.058 (95% CI 1.002-1.123, p = 0.044), respectively. In the bradycardia with dexmedetomidine group, the infusion rate of dexmedetomidine was 0.41 +/- 0.15 microg/kg/h. Decisions of charged doctor's were 1) slowing infusion rate and 2) stopping infusion or administering atropine for bradycardia. No cases required cardiac pacing or worsened to asystole. CONCLUSIONS: Despite the frequent occurrence of bradycardia after administration of dexmedetomidine during 33degrees C target temperature management, bradycardia was completely recovered after reducing infusion rate or stopping infusion. However, reducing the infusion rate of dexmedetomidine lower than the standard maintenance dose could be necessary to prevent bradycardia from developing in patients with higher body weight or carbon monoxide poisoning during 33degrees C targeted temperature management.

Epidermolytic keratosis palmaris is a rare disease which shows clinical findings of Unna Thost keratoderma and histopathologic of epidermolytic hyperkeratosis. We report herein a case of epidermolytic keratosis palmaris et plantaris in a 16-month-old female baby. Light microscopy shows marked hyperkeratosis, large irregular keratohyalin granules, and large clear spaces in the granular and upper spinous layers. Eletron microscopic findings shows that the clear spaces are areas of cytoplasm filled with a fibrillar material and cellular organelles. Abnormal clumping of tonofilament and keratohyalin is also present.

BACKGROUND: Direct wet mount examination of vaginal secretion, widely applied for the diagnosis of Trichomonas vaginalis infection in woman patients, is rapid and economical. However, the sensitivity of this technique is not so high. In this study enzyme-linked immunosorbent assay(ELISA) was employed for the detection of serum anti-T. vaginalis IgG antibodies from vaginal trichomoniasis patients. METHODS: Eighty sera from trichomonoasis patients who visited a Dr. Yoon Kyong's Obstetric & Gynecologic Clinic in Songnam and 30 non-infected healthy men were tested for detection of anti-T. vaginalis IgG antibody. Soluble lysate and excretory-secretory antigen prepared by mixing of six isolates of T. vaginalis, and lysate from one isolate(KT4) were used as antigen for ELISA. RESULTS: The sensitivity of ELISA using lysate of six isolates was 95.0%, and the sensitivity of the lysate from KT4 and mixed excretory-secretory antigen from 6 isolates were 86.4% and 76.3%, respectively. Specificities of ELISA by three 93.3%, 96.3% and 92.0%, respectively. CONCLUSION: It is suggested that ELISA using mixed lysate of T. vaginalis six isolates could be useful tools for the diagnosis of trichomoniasis.

Cavernosography after injection of papaverine was done in 25 impotent patients who showed equivocal evidence for either psychogenic or organic erectile dysfunction and who were strongly suspicious of having vasculogenic impotence. Diagnostic value of the pharmacocavernosography was evaluated. Venous leakages through deep dorsal vein were noted in 13 patients, out of whom 3 patients showed leakage also via deep vein, abnormal cavernosal vein or cavernoso-glans fistula. All the arteriogenic and psychogenic, but 38.5% of the venogenic impotents, showed full erection at 30 seconds after infusion of contrast medium was begun. The response to injection of the papaverine was well correlated with findings of the cavernosogram in venogenic and psychogenic impotents. Therefore, the pharmacocavernosography is valuable in differential diagnosis of the venogenic and arteriogenic impotence as well as in diagnosis of the vasculogenic impotence.

10.Effects of (6)-gingerol, ginger component on adipocyte development and differentiation in 3T3-L1.
Journal of Nutrition and Health 2015;48(4):327-334
PURPOSE: The objective of this study was to investigate the effects of (6)-gingerol, ginger components proliferation and adipocyte differentiation from early to lately steps. METHODS: 3T3-L1 preadipocytes were cultured. Differentiation of confluent cells was induced with dexamethasone, isobutylxanthin and insulin for 2 day and cells were cultured by medium with insulin in presence of various concentrations 0, 25, 50, 100 (micromol/L) of (6)-gingerol for 4 day. Cell viability was measured using the EZ Cytox assay kit. In addition, we examined the expression of mRNA levels associated with each adipocyte differentiation step by real time reverse transcription polymerase chain reaction. RESULTS: (6)-Gingerol inhibited adipocyte proliferation in a dose and time dependent manner. Expression of C/EBPbeta, associated with early differentiation step remained unchaged. However, intermmediate, late differentiation step and adipocytokines were effectively changed in dose-dependently manner in cell groups treated with (6)-gingerol. CONCLUSION: This study has shown that treatment with (6)-gingerol inhibited adipocyte proliferation as well as each adipocyte differentiation step. In particular, the (6)-gingerol more effectively inhibited adipocyte differentiation from intermmediate differentiation step.
