Adnexal torsion is not a common surgical emergency in obstetrics and gynecology, and is not observed frequently during pregnancy with its incidence being one out of about 5,000 pregnancies: pregnancy is a factor that encourages torsion. The traditional treatment for ischemic and twisted adnexa consists of oophorectomy or salpingo-oophorectomy. With early diagnosis. a conservative approach is recommended in cases of young women to assure future fertility. With a brief review of literature, we report a case of unilateral salphingo-oophorectomy during pregnancy due to adnexal torsion with the delivery of a normal baby.

This stduy was carried out to evaluate the ability of clinical application of pregnancy diagnosis based upon the determination of progesterone in serum, utilizing EIA-kit of progesterone concentrations in the serum were assayed by radioimmunoassay. 1. The progesterone concentrations of the pregnant cows(2.40$\pm$0.34ng/ml) were significantly higher than those of non-pregnant cows(1.03$\pm$0.09ng/ml), and thereafter began to increase and maintained high levels. 2. During 20 to 22 days after artificial insemination, the accuracy of pregnancy diagnosis from EIA-kit of progesterone were 95.0% for non-pregnant cows, and 92.3% for pregnant cows. 3. During 20 to 22 days after artificial insemination, the accuracy of pregnancy diagnosis from serum progesterone concentrations were 100% for non-pregnant cows(<1.4ng/ml), and 96.2% for pregnant cows( 2.0ng/ml). The average overall accuracy of prediction for pregnant and non-pregnant cows were 98.1%. 4. Accordingly, the pregnancy diagnosis from EIA-kit of progesterone is thought to be recommendable because this early diagnostic means are simple with accurate results.

Purpose: This study examined the influencing factors on antenatal depression among pregnant women. Methods: This was a cross sectional descriptive study with 255 pregnant women who visited a general hospital in a metropolitan city for their regularly scheduled check-up. Measurement tools employed were the Korean version of Beck Depression Inventory (BDI), the food habits, and the Pittsburg Sleep Quality Index (PSQI). Socio-demographic variables and the status of high risk pregnancy were identified. Influencing factors on antenatal depression were identified using a stepwise multiple regression analysis. Results: The mean score of antenatal depression was $7.2{\pm}5.0$; 18.4% with mild depression, 5.9% had moderate depression, with 0.8% identified with severe depression on BDI scale. Influencing factors on antenatal depression accounted for 47.8% of the total variance which consisted of quality of sleep, marital satisfaction, food habits, gestation periods, sexual satisfaction, high risk pregnancy, and age. Conclusion: Findings show that antenatal depression should be monitored on a regular basis during early pregnancy and in high risk pregnancy if possible, and quality of sleep and food habits should be incorporated in the management of antenatal depression.

This study was conducted to find out the changes of progesterone and estrone sulphate concentration in serum of Korean native goats throughout gestation, and to apply the serum levels of the hormones to pregnancy diagnosis. Serum concentration of progesterone and estrone sulphate were assayed by radioimmunoassay. Serum progesterone concentration was similar to its luteal phase values during early pregnancy and remained at the high level continually at 20∼140days and decreased rapidly at the day of parturition. Serum estrone sulphate concentration showed to increase markedly at 40∼50dyas gestation and steadily increased to the maximum of 7.13ng/ml at 140days, but declined sharply at the day of parturition. The accuracy of pregnancy diagnosis by the measurement of serum progesterone at 20∼24days after mating was 85.7∼92.3% and that of non-pregnancy diagnosis was 100%, when the serum progesterone levels higher and lower than 3.0ng/ml were supposed to indicate pregnancy and non-pregnancy, respectively. The accuracy of pregnancy diagnosis by the mearsurement of serum estrone sulphate was found to be nearly 100% since 50days after mating, when the serum levels of estrone sulphate higher then 0.5ng/ml were diagnosed to be pregnant. The optimal sampling time for pregnancy diagnosis was considered to be at 50 days after mating or to be later. It appears that estrone sulphate values above 7.0ng/ml at any time in gestation are highly indicative of twin. But there was found no significant difference(P<0.05) in serum estrone sulphate concentration and number of kids between does with single and twin kids.

Abdominal pregnancy is a very rare form of ectopic pregnancy following IVF-ET procedure. Because the symptoms of abdominal pregnancy is not typical, it is difficult to diagnose early and the mortality rate is higher than other ectopic pregnancies. Liver, spleen, omentum and diaphragm are main implantation sites of abdominal pregnancy. We reported an unusual first case of an etopic pregnancy on uterosacral ligament following in vitro fertilization and embryo transfer with brief review of literature.

Objective: Leukemia inhibitory factor (LIF) binds to a heterodimeric receptor composed of LIF receptor (LIFR) and glycoprotein 130 (GP130) to transmit signals into the cell. LIF plays an important role in reproduction by regulating immune response, decidualization, and implantation in several species. However, the expression of LIF and LIFR in the endometrium throughout the estrous cycle and pregnancy in pigs is not fully understood. Methods: We analyzed the expression of LIF and LIFR in the endometrium on days 0 (estrus), 3, 6, 9, 12, 15, and 18 of the estrous cycle, and days 12, 15, 30, 60, 90, and 114 of pregnancy, in conceptuses on days 12 and 15, and in chorioallantoic tissues on days 30, 60, 90, and 114 of pregnancy in pigs. We also determined the effects of estrogen and progesterone on the expression of LIF and LIFR in endometrial tissues. Results: The expression of LIF increased in the endometrium during the late diestrus phase of the estrous cycle and during mid- to late- pregnancy, while the expression of LIFR increased during early pregnancy. The expression of LIF was induced by increasing doses of estrogen, whereas the expression of LIFR was induced by increasing doses of progesterone. Conclusion: These results indicate that the expression of LIF and its receptor LIFR in the endometrium is regulated in a stage-specific manner during the estrous cycle and pregnancy, suggesting that LIF and its receptor signaling system may play critical roles in regulating endometrial function in pigs.

The present study was conducted in a goat farm for pregnancy diagnosis by using vaginal cytology and B-mode real time ultrasound using 5 MHz probe by transabdominal method. Seventeen pregnant does were used for this study. The objective of the study was to determine the earliest day of pregnancy and describe the chronological characteristics of pregnancy from day 22 to day 40 for vaginal cytology and day 25 to day 60 for ultrasonography of gestation. The differences among the average percentage of cell value in different age of pregnancy were significant (p < 0.05). The average percentage of intermediate cells (81.12%) was also significantly (p < 0.05) higher than superficial (9.41%), keratinized (7.10%) and neutrophil (2.61%) on 22-40th days of pregnancy. In case of real time B-mode ultrasonography, the gestational sac was observed only in three does out of seventeen (17.6 %) at 25-30 days whereas the placentomes and heart beat of the foetus were first detected at 31-35 days in six does (35.3%). The foetal leg buds were first visualized at 36-40 days in four does (23.5%) whereas the foetal vertebral column was first observed at 36-40 days of gestation in only three does (17.6%). In conclusion, vaginal cytology and trans-abdominal ultrasonography can be used for detection of early pregnancy in does.

This study was carried out to improve a technique of embryo transfer for twin calves production in Hanwoo cattle. Blastocysts for the donor of embryo transfer were classified into three criteria by accessment of morphology; early blastocyst, blastocyst and expanded blastocyst. Tow embryos were introduced transcervically into utrerine horn either of Hanwoo or Holstein by ipsilaterally or contralaterally to the corpus luteum. Thiry-six out of 57 recipients cows were inseminated by artificially on the next day of estrus, and followed by transfer of embryos into contralaterally. The pregnance rates of recipients following transfer of bovine embryos of day 7, 8 and 9 was 43.5, 18.2 and 8.3%, respectively. These results appeared that these was a significant (P<0.05) difference between on day-7 embryos and day-9 embryos, but not between on day-8 and day-9 embryos. Although there was not significant(P<0.05) difference in the pregnancy rates between the blastocysts(11/25, 44%) and expanded blastocysts(2/19, 10.5%) and between the blastocysts and early blastocysts(2/13, 15.4%), the embryos at blastocyst stage are more suitable than others for obtaining higher rate of pregnancy. There was no significant difference on pregnancy of the embryos transferred prior to presence(6/21, 29%) or absence (9/36, 25%) of artificial insemination. On pregnancy of Holstein, 2(15.4%) out of 13 recipients were pregnant in heifer. Similar Pregnancy rates were obtained between 1∼2 parities and 3∼4 parities by 30% (6/20) and 27.3%(3/11), respectively. Taken together, there was not significant difference in pregnancy rate due to small number of recipients used for this experiment. Both of Hanwoo and Holstein introduced the embryos by contralsterally to the corpus luteum were slightly higher pregnancy rate compare to by ipsilaterally (12/41, 29.3% vs, 3/16, 18.8%). The ratio of production of twin and single calves in Holstein was 20% (9/45) and 2.2% (1/45), respectively. However, in Hanwoo cows both of production of twin and single were similar as 8%. This result suggests that Holstein as recipients was superior to Hanwoo cows for production of twin calves. Out of all 15 pregnant, 12(80%) were produced a total of 22 normal calves in which the others composed of abnormal, as judging as 2(13.3%) for abortion and 1(6.6%) for stillbirth during the pregnant period.
