A 1-year-old, intact female, Yorkshire terrier was referred with diarrhea and depression. Fecal examination indicated overgrowth of yeast-like organisms. CBC and blood smear revealed severe leukemoid reaction with degenerative changes of neutrophils. Radiographic examination showed decreased serosal detail and organomegaly, suggesting pyometra with peritonitis. Thus, the dog was suspected as pyometra with peritonitis. Culture and molecular analysis of the yeast-like organisms revealed that overgrown yeast was Candida parapsilosis.

Objective: The aim of this study was to evaluate the influences of uterine septum and their elimination on the reproductive outcomes in women who have history of recurrent spontaneous abortion (RSA) and/or infertility. Methods: The medical records of reproductive outcomes in patients who have had history of RSA and infertility who were diagnosed with uterine septum only by hysterosalpingogram (HSG) between January 2008 and December 2009 were retrospectively analyzed. The subjects who have had severe male factor, tubal factors, other uterine factors, endocrine abnormalities, peritoneal factors, and abnormal karyotyping among both partners were excluded. In 27 patients, confirmation of diagnosis by laparoscopy and elimination of uterine septum by trans-vaginal hysteroscopy was done. Seventeen patients were strongly suspected to uterine septum on HSG but tried to get pregnancy without any other procedure for evaluation and management of uterine anomaly. Age matched 42 patients who have history of RSA and/or infertility and diagnosed to normal HSG finding at same period were randomly selected as control. The medical records of reproductive outcomes were analyzed and compared between groups. Results: The mean time of observation after diagnosis was 21.8 months (10 to 32). 55.6% (15/27) of patients in patients who received trans-vaginal hysteroscopic uterine septotomy were success to get pregnancies and was significantly higher than that of 17 patients who did not receive proper management (23.5%, 4/17, p<0.05). In control population, 40.5% (17/42) were success to pregnancies and the differences were not statistically significant compared to both two study groups. The live birth rate which was excluded pregnancy loss by abnormal fetal karyotyping and congenital anomaly were 75% (9/12) in treated septated uterus group and 84.6% (11/13) in control group each which have no statistically significant different. In patients with septated uterus who did not receive proper management showed lower delivery rate (50%, 2/4) than that of other groups but was not statistically significant. Conclusion: According to present data, women with a uterine septum have an increased chance of successful pregnancy with improved obstetric outcome after proper management of the uterine cavity. And these results were showed in patients with no regard to their reproductive history. But, in case of failed to receive proper management, uterine septum can affect not only pregnancy ongoing but successful pregnancy too.

최근 적절한 사양관리를 위해서 유중 요소태질소 수준(MUN)과 유단백을 이용하여 사료 내 에너지와 단백질의 균형을 평가하는 지표로 활용하고 있으며 요소태질소 수준이 정상보다 크게 높거나 낮았을 때 번식능력이 저하되기 때문에 번식효율의 지표로서 활용되고 있다. 따라서 본 연구에서는 우유내 요소태질소 수준이 번식장애에 미치는 영향을 조사하여 요소태질소 수준을 번식장애의 진단지표로 활용하고자 실시하였다. 본 실험에 공시된 우유시료는 경기도 안성시와 이천시에 소재한 낙농목장에서 사육중인 조사두수를 대상으로 개체당 약 30~50$m\ell$의 우유를 채유하고 냉장보관하여 실험실로 운반하였다. 우유의 분석은 유성분분석기(Fosscomb : 4000, Fossmatic 5000, Denmark)를 이용하여 우유의 일반성분인 유지방, 유당, 유단백, 무지고형분, 총고형분, 빙점, 유중요소태질소, 구연산과 체세포를 동시에 분석하였다. 번식장애우의 진단은 낙농가가 번식장애우로 분류한 개체를 대상으로 직장검사 및 초음파 진단기를 이용하여 진단하였다. MUN준에 따른 공태일수의 조사 결과 MUN수준이 7이하 군의 공태일수가 88.98$\pm$120.68로 7-16의 92.20$\pm$105.39와 16이상의 94.42$\pm$87.51보다 다소 낮은 결과를 나타냈다. 또한 번식장애우의 발생빈도와 유성분 분석결과를 살펴보면 낙농가가 번식장애우로 분류한 68두를 진단한 결과 발정발견을 하지 못하여 번식장애우로 분류된 두수가 30두(44.1%)와 비정상두수 38두(55.9%)로 나타났으며 비정상 두수 중 난포난종이 19두(27.9%)로 영구항체6두(8.8%), 자궁내막염(10.3%), 자궁축농증 6두(8.8%)보다 많은 것으로 나타났다. 번식장애우의 유성분 분석결과 자궁축농증이 있는 개체의 유단백 평균이 3.43$\pm$0.35로 다른군에 비해 높았으며 영구항체가 있는 개체군의 MUN수준이 7.73$\pm$8.58로 다른군의 10.84$\pm$4.92, 10.89$\pm$7.38와 10.61$\pm$5.52에 비해 낮게 나타났다.

Objective: To investigate assisted reproductive technology (ART) outcomes in women with WHO class I anovulation compared with control group. Design: Retrospective case-control study. Methods: Twenty-three infertile women with hypogonadotropic hypogonadism (H-H) who undertook ART procedure from August 2003 to January 2009 were enrolled in this study. A total of 59 cycles (H-H group) were included; Intra-uterine insemination with super-ovulation (SO-IUI, 32 cycles), in vitro fertilization with fresh embryo transfer (IVF-ET, 18 cycles) and subsequent frozenthawed embryo transfer (FET, 9 cycles). Age and BMI matched 146 cycles of infertile women were collected as control group; 64 cycles of unexplained infertile women for SO-IUI and 54 cycles of IVF-ET and 28 cycles of FET with tubal factor. We compared ART and pregnancy outcomes such as clinical pregnancy rate (CPR), clinical abortion rate (CAR), and live birth rate (LBR) between the two groups. Results: There was no difference in the mean age ($32.7{\pm}3.3$ vs. $32.6{\pm}2.7$ yrs) and BMI ($21.0{\pm}3.1$ vs. $20.8{\pm}3.1kg/m^2$) between two groups. Mean levels of basal LH, FSH, and $E_2$ in H-H group were $0.62{\pm}0.35$ mIU/ml, $2.60{\pm}2.30$ mIU/ml and $10.1{\pm}8.2$ pg/ml, respectively. For ovarian stimulation, H-H group needed higher total amount of gonadotropin injected and longer duration for ovarian stimulation (p<0.001). In SO-IUI cycles, there was no significant difference of CPR, CAR, and LBR between the two groups. In IVF-ET treatment, H-H group presented higher mean $E_2$ level on hCG day ($3104.8{\pm}1020.2$ pg/ml vs. $1878.3{\pm}1197.7$ pg/ml, p<0.001) with lower CPR (16.7 vs. 37.0%, p=0.11) and LBR (5.6 vs. 33.3%, p=0.02) and higher CAR (66.7 vs. 10.0%, p=0.02) compared with the control group. However, subsequent FET cycles showed no significant difference of CPR, CAR, and LBR between the two groups. Conclusion: H-H patients need higher dosage of gonadotropin and longer duration for ovarian stimulation compared with the control groups. Significantly poor pregnancy outcomes in IVF-ET cycles of H-H group may be due to detrimental endometrial factors caused by higher $E_2$ level and the absence of previous hormonal exposure on endometrium.

The clinical features of ring chromosome 13 include mental and growth retardation, CNS anomalies, facial dysmorphism, cardiac defects, genital malformations, limb anomalies, skeletal deformities and anal malformations. Although many cases of ring chromosome 13 have been reported worldwide, only 6 cases have been reported in Korea, and the latter cases were not mosaic but pure ring chromosome 13. Here we report a case with mosaic ring chromosome 13. The baby boy was born at 37 weeks of gestation by induced vaginal delivery due to intrauterine growth restriction (IUGR). He was the second baby of a 28-year-old hepatitis B carrier mother and a 32-year-old father. There was no family history of chromosomal anomalies. The baby was a symmetric IUGR with a birth weight of 1,860 g, length of 44.8 cm, and head circumference of 29.4 cm. The physical examination revealed microcephaly, trigonocephaly, flat occiput, large ears, short neck and dysmorphic facial features, including microophthalmia, hypertelorism, antimongoloid slanting palpebral fissures, a flat nasal bridge, and micrognathia. The karyotype of this patient performed by peripheral blood lymphocytes was 46,XY,r(13)(p13q34)/45,XY,-13/46,XY,dic r(13;13)(p13q34;p13q34). The baby showed failure to thrive, hypotonia, and developmental delay. We report the first case of mosaic ring chromosome 13 in a male baby in Korea and compare this case with other Korean cases of non-mosaic ring chromosome 13.

인공수정 및 수정란기술의 활성화에 따라 소에 있어서 인공수정은 90%이상이 실시되고 있으나, 수정란이식은 수정란의 생산이 안정적이지 않아 활성화에 많은 지장을 초래하고 있다. 이의 원인은 수정란이식에 의한 수태율의 저하가 가장 크며, 수태율 향상을 위하여 수란우에 progesterone, hCG 등의 주사가 실시되고 있다. 그러나 이는 수정란의 착상에 있어서 자궁의 환경을 개선한다고 하나, 착상의 정확한 기전의 구명은 미미한 상태이다. 한편 비장유래 macrophage가 황체를 자극하고 TGF-$\beta$의 생산을 유도하는 것으로 보고되고 있으며, IL-I $\alpha$와 $\beta$에 따라 TGF-$\beta$ 생산에 있어서 약간의 차이를 보이는 것으로 보고되고 있다. 따라서 본 연구는 비장유래 macrophage가 TGF-$\beta$의 생산시 임신관련 Cytokine인 IL-I$\alpha$와의 관계를 조사하기 위하여 실시하였다. 임신 및 비임신 도축 암소의 비장을 채취하여 얼음에 채워 실험실로 운반한 후 비장의 표면을 70%의 알콜로 세척하고, 표피를 벗겨 비장조직을 세절하여 10% FBS+DMEM에 넣어 조직을 눌러 짜면서 조직속의 세포를 분리하였다. 세척한 배양액은 4-5$m\ell$를 100mm 유리 petri dish에 넣고 39$^{\circ}C$, 5% $CO_2$, 95% 공기인 배양기에서 2시간이상 배양하였으며, 배양 후 냉장된 buffer A 용액으로 세척하여 유리 petri dish의 바닥에 부착된 macrophage만을 cell scraper로 분리하였다. 분리한 macrophage는 0.5-1 $\times$ $10^{6}$ cells/$m\ell$가 되게 조정하여, IL-I 을 0.001, 0.01, 0.1 또한 1 ng/$m\ell$를 첨가하여 농도에 따른 효과를 조사하였고, 각각 24, 48, 72, 96 또한 120시간을 배양하여 시간에 의한 효과도 실시하였다. 각 배치구에서 얻어진 배양액은 TGF-$\beta$를 조사하기 전까지 -2$0^{\circ}C$에 동결 보존하였다. TGF-$\beta$의 측정은 TGF-$\beta$ kit(promega, USA)를 이용하여 실시하였으며, 통계학적 분석은 Anova test를 Statview program을 이용하여 분석하였다. 시험의 결과 대조구에 비해 IL-I 첨가구는 2-3배의 TGF-$\beta$생산을 보였으며, 배양시간에 따른 생산은 시간이 지남에 따라 약간 상승하는 경향을 보였으나, 유의적인 차이를 보이지는 않았다. 또한 IL-I의 농도에 따른 생산의 변화는 IL-I의 농도에 따라 약간의 차이를 보였고 유의적인 차이는 인정되지 않았다. 임신 및 비임신의 경우 임신우의 비장 macrophage가 비임신보다는 약간 상승하는 거스로 나타났다. 이상의 결과로 볼 때 IL-I $\alpha$ 는$\beta$subunit 보다 TGF-$\beta$ 생산에 있어서 서로 다른 양상을 보일 것으로 추정되며, IL-I은 macrophage의 직접적인 영향을 주기보다는 황체세포를 매개로 한 자궁에 TGF-$\beta$의 생산을 유도하는 것으로 사료되며, 임신관련 cytokine에 대한 다양한 연구가 요구되고 있다.

Sulforaphane, an isothiocyanate derived from hydrolysis of glucoraphanin in broccoli and other cruciferous vegetables, was shown to induce phase II detoxification enzymes and inhibit chemically induced mammary tumors in rodents. Recently, sulforaphane is known to induce cell cycle arrest and apoptosis in human cancer cells, however its molecular mechanisms are poorly understood. In the present study, we demonstrated that sulforaphane acted to inhibit proliferation and induce morphological changes of human cervical carcinoma HeLa cells. Treatment of HeLa cells with $10{\mu}M\;or\;15{\mu}M$ sulforaphane resulted in significant G2/M cell cycle arrest as determined by flow cytometry. Moreover, $20{\mu}M$ sulforaphane significantly induced the population of sub-G1 cells (9.83 fold of control). This anti-proliferative effect of sulforaphane was accompanied by a marked inhibition of cyclin A and cyclin-dependent kinase (Cdk)4 protein and concomitant induction of Cdc2, Cdk inhibitor p16 and p21. However, sulforaphane did not affect the levels of cyelooxygenases and telomere-regulatory gene products. Although further studies are needed, the present work suggests that sulforaphane may be a potential chemoprevetive/ chemotherapeutic agent for the treatment of human cancer cells.

Purpose: Troglitazone (TRO), a PPAR-$\gamma$ agonist, can reduce heat shock protein (HSP) 70 and increase the antioxidant enzymes, such as superoxide dismutase (SOD) and catalase, which might affect thermal sensitivity. Here, we investigated whether TRO modifies thermal sensitivity in uterine cervical cancer cells, which is most commonly treated by hyperthermia (HT). Materials and Methods: HeLa cells were treated with $5{\mu}M$ TRO for 24 hours before HT at $42^{\circ}C$ for 1 hour. Cell survival was analyzed by clonogenic assay. The expression of HSPs was analyzed by Western blot. SOD and catalase activity was measured and reactive oxygen species (ROS) was measured using 2',7'-dichlorofluorescin diacetate and dihydroethidium. Results: The decreased cell survival by HT was increased by preincubation with TRO before HT. Expression of HSP 70 was increased by HT however, it was not decreased by preincubation with TRO before HT. The decreased Bcl-2 expression by HT was increased by preincubation with TRO. SOD and catalase activity was increased by 1.2 and 1.3 times,respectively with TRO. Increased ROS by HT was decreased by preincubation with TRO. Conclusion: TRO decreases thermal sensitivity through increased SOD and catalase activity, as well as scavenging ROS in HeLa cells.

We determined the maternal peripheral lymphocyte response to mitogen during the period of implantation and evaluated the effects of hormones, which are known to be involved in the process of implantation, on the lymphocyte activity in rabbits. As compared with peripheral lymphocyte activity in non-pregnant rabbits, lymphocyte activity was significantly depressed on days 6, 7 and 9 of pregnancy. Although concentrations of serum progesterone were gradually increased during the implantation period, progesterone did not inhibit lymphocyte activity at physiological concentration. Serum $PGF_{2{\alpha}}$ was significantly increased on day 7 while PGE was slightly increased. $PGF_{2{\alpha}}$ did not modify lymphocyte activity even with greater concentrations than physiological level. However, lymphocyte activity was significantly inhibited by PGE even with physiological doses. The treatment of indomethacin at doses of 0.1 or $1.0\;{\mu}g/ml$ tended to enhance lymphocyte response, which was depressed on day 8 of pregnancy, 28% or 23% respectively. Although in non-pregnant rabbit, enhancement of lymphocyte response was also shown after the treatment of indomethacin, this enhancement was much less than that in pregnant rabbits. These results strongly suggest that maternal immune response was depressed during the process of implantation and PGE might be one of factors for immunomodulation during this period.
