The purpose of this paper is to assimilate all data pertaining to the use of gonadotropin-releasing hormone (GnRH) antagonists in in vitro fertilization cycles after ovulation trigger to reduce the symptoms of ovarian hyperstimulation syndrome (OHSS). A systematic review of the literature was performed to identify all studies performed on the use of a GnRH antagonist in IVF cycle post-ovulation trigger with patients at high risk for OHSS. Ten studies were identified and reviewed. Descriptions of the studies and their individual results are presented in the following manuscript. Due to significant heterogeneity among the studies, it was not possible to perform a group analysis. The use of GnRH antagonists post-ovulation trigger for treatment of OHSS has been considered for almost 20 years, though research into its use is sparse. Definitive conclusions and recommendations cannot be made at this time, though preliminary data from these trials demonstrate the potential for GnRH antagonists to play a role in the treatment of OHSS in certain patient populations.

Thalictrum species belongs to the Ranunculaceae and are perennial landscape plants which are available in the garden and potted plants. This experiment was conducted to find out the basic data for the growth effects of fertilizer levels and shading rate in seedling plug cell tray in the Thalictrum rochebrunianum, T. uchiyamai and T. coreanum. For T. rochebrunianum and T. uchiyamai, growth increased by all fertilizer level treatments as compared to non-treatment. Hyponex 1000 times of treatment showed the highest growth. All growth increased in 35% shading as compared to other treatments for T. rochebrunianum and T. coreanum. But, for T. uchiyamai growth increased in 55% shading. In general, growth of three Thalictrum species was worse in 75% shading, as compared to other shading rates. Based on the results, Thalictrum species seedling can be produced by 35-55% shading and fertilization of Hyponex 1000 times by using plug tray.

This experiment was carried out to determine the possibility of using FDA on the selection of viable bovine immature oocytes. The results obtained in these experiments were summarized as follows; 1. The rates of nuclear maturation (metaphase II) of bovine oocytes according to FDA concentration were 92.5% (37/40) in the control and those rates in the dilution on FDA to 1:400,000, 1:800,000 and 1:1,600,000 were 74.4% (67/90), 80.3% (38/46) and 71.1% (32/45), respectively. 2. The fertilization rate ( 2-cell) in the control was 72.2% (39/54) and those rates in the dilution of FDA to 1:400,000, 1:800,000 and 1:1,600,000 were 28.8% (23/80), 66.7% (32/48) and 62.2% (28/45), respectively. In these results, a, pp.opriate concentration of FDA to bovine immature oocytes was 1:800,000. 3. Effect of FDA treatment to the blastocyst development of bovine oocytes was indicated that control was 22.2% (18/81) and FDA treatment groups which were classified to strong, partial and weak were 21.4% (36/168), 14.5% (9/62) and 0% (0/15), respectively. This result suggested that in vitro development to the blastocyst was severely reduced except strong group according to the FDA fluorescent level (P<0.05) and that using FDA is possible to select of bovine oocytes.

Chronic endometritis (CE) is a condition involving the breakdown of the peaceful co-existence between microorganisms and the host immune system in the endometrium. A majority of CE cases produce no noticeable signs or mild symptoms, and the prevalence rate of CE has been found to be approximately 10%. Gynecologists and pathologists often do not focus much clinical attention on CE due to the time-consuming microscopic examinations necessary to diagnose CE, its mild clinical manifestations, and the benign nature of the disease. However, the relationship between CE and infertility-related conditions such as repeated implantation failure and recurrent miscarriage has recently emerged as an area of inquiry. In this study, we reviewed the literature on the pathophysiology of CE and how it may be associated with infertility, as well as the literature regarding the diagnosis and treatment of CE. In addition, we discuss the value of hysteroscopic procedures in the diagnosis and treatment of CE.

Objectives: This study is to evaluate the effect of KI06 acupuncture point in the first trimester vaginal bleeding of a threatened abortion patient. Methods: A patient of threatened abortion was treated consequently with KI06 acupuncture point, and the result was inspected and evaluated using sono. Results: After consequent 4 times KI06 acupuncture point treatments, amount and frequency of bleeding in a patient of threatened abortion decreased to 80%, 50%, 20%, 10%. after more treatment the first trimester vaginal bleeding was improved completely. Conclusions: Treatment of KI06 acupuncture point in a threatened abortion patient was effective and further study is needed.

Combined pregnancy occasionally occurs when intrauterine pregnancy is complicated with ectopic pregnancy. The incidence of combined pregnancy is normally rare, but the incidence increases when assisted reproductive technology was conducted for infertility treatment. We had a case of intrauterine pregnancy complicated with tubal pregnancy after IVF-ET cycle was conducted. The tubal pregnancy was removed via pelviscopy, which led to the delivery of healthy offspring at the $39^{th}$ week of pregnancy without additional complication.

Chimerism has become an important tool for investigating fundamental aspects of early embryonic development and differentiation in mammals for producing transgenic animals. The objective of this study was to evaluate the developmental capacity of chimeric embryos reconstructed with parthenotes and IVF bovine embryos into empty zona pellucida. The MII oocytes were activated by two treatment groups [Group 1, 5 μM inomycin, 5min, ＋ 10 ㎍/㎖ cycloheximide (CHX)/5 ㎍/㎖ cytochalasin B (CCB), 3 h; Group 2, 5 μM ionomycin, 5 min ＋ 1.9 mM 6-dimetylaminopurine (6-DMAP), 3 h].

Pregnancy and delivery are the God's blessing as well as the right of all married women. But, these are agonizing events for the infertile women. Therefore, supportive nursing care for the infertile women is crucial in the process of diagnosis and treatment of infertility. The introduction of In Vitro Fertilization is a solution for infertility. But we take it serious that such socio-cultural factors as patriarchism, sex role, and motherhood are negatively influencing infertility women's experiences. Thus, nurses who take care of the infertile women need to have feministic perspectives as well as medical information, and expertise so that they could reach a comprehensive understanding on infertile women's experiences.

In both untreated and conventionally stabilized swine manures antibiotic resistant (AR) microorganisms, Staphylococcus-like and Salmonella-like microorganisms were detected. Also pathogens with MAR phynotype were detected. Presence of such microorganisms suggest high level of pathogen-related health risk to farmers who may be in direct contact with the manure and its conventionally stabilized product In contrast the autothermal thermophilic aerobic digestion (ATAD) treatment have efficiently reduced AR and pathogenicity from the swine manure. When soil was fertilized using swine manure and its stabilized products, despite no detection of MAR-exhibiting pathogen-like microorganisms in fertilized soil, potential pathogen-related health risk could not be ruled out from the fertilized soil since the organic fertilization led to increase in AR and pathogenicity in the soil microbial communities. As conclusion, this microbiological study demonstrated that an ATAD process is applicable in control of pathogen-related health risk in livestock manure.

Spermiation was stimulated in the mature grass puffer, Takifugu niphobles, with an injection of human chorionic gonadotropin (HCG) or carp pituitary extract (CPE). Spermatocrit and sperm density were reduced, but milt production was increased in both the HCG and CPE treatment groups relative to those in the control group (P < 0.05). These results should be useful for increasing the fertilization efficiency in grass puffer breeding programs.
