Objective: The purpose of this study was to determine the important factors affecting survival and pregnancy rate in frozen-thawed embryo transfer cycles. Methods: we performed retrospective analysis in 738 cycles of frozen-thawed embryo transfers, in relation to the insemination methods, the freezing stage of embryo, patient's age, infertility factors and the origin of injected sperm in ICSI cycles. After conventional IVF or ICSI, the supernumerary PN stage zygotes or multicellular embryos were cryopreserved by slow freezing protocol with 1,2-propanediol (PROH) as a cryoprotectant. Results: The survival rates of thawed embryos were 69.3% (1585/2287) in conventional IVF group and 71.7% (1645/2295) in ICSI group. After frozen-thawed embryo transfers, 27.0% (92/341) and 32.0% (109/341) of pregnancy rates were achieved in conventional IVF and ICSI group, respectively. There were no significant difference in the survival and pregnancy rates according to the insemination methods, the freezing stage and patient's age. However, the pregnancy rate (36.2%) of male factor infertility was significantly higher than the tubal (27.2%) and other female factor infertility (22.9%). In ICSI group, the origin of injected sperm did not affect the outcome of frozen-thawed embryo transfer cycles. Conclusion: The present study demonstrates that acceptable clinical outcomes can be achieved after the transfer of frozen-thawed embryos regardless of the stage of embryos for freezing, the patient's age and the origin of injected sperm.

Achalasia can be provoked by organic causes, and it is called secondary achalasia. Sometimes it is very difficult to distingush secondary achalasia from primary achalasia. We report a case of secondary achalasia due to recurrence of stomach cancer. A 45-year-old man came to our hospital due to three months history of dysphagia and regurgitation. Barium esophagogram showed concentric narrowing at the distal esophagus and dilatation of proximal esophagus. The esophagogastroduodenoscopy showed stenosis of gastroesophageal junction and the endoscope could not pass through it, but there was no evidence of malignancy. Esophageal manometry showed aperistalsis, compatible with achalasia. Abdominal CT showed soft tissue density near the gastroesophageal junction. However it was not possible to differentiate whether it was due to adhesion or malignancy. For correct diagnosis and treatment, explorolaparotomy was performed and it was diagnosed as secondary achalasia due to recurrence of stomach cancer.(Korean Journal of Gastrointestinal Motility 2002;8:53-57)

N/A Objective: A dichotomous Thl and Th2 cytokine profile has been associated with reproductive failure and success, respectively. The purpose of our study was to determine the levels of Thl cytokine (IFN- y ) secreted by peripheral blood mononuclear cells (PBMCs) form women with unexplained recurrentabortion (URA) and fertile controls in response to trophoblast antigen. Methods: PBMCs were isolated from 30 nonpregnant women with URA and from 10 nonpregnant fertile controls. Following 4 days of culture (1 * 10(6) cells/mL) with and without a protein extract derived from a trophoblast cell line (30 ug/mL, protein). None of the women had allergies, atopy or recent infection. Cytokines were measured in supernatants with enzyme-linked immunosorbent assay (ELISA) kits. IFN- r kit was obtained from BOISOURCE (lower limit of sensitivity, 15.6 pg/mL for IFN- r ). All values below the lowest limit of sensitivity as determined by test kit standards were considered negative. The cytokine stimulation test is considered positive if the IFN- r concentration increases by 200% or more with the trophoblast antigen stimulation. Datas are presented as mean+ SEM. Nonparametric testing (Mann-Whitney U) was used for analysis with P<0.05 considered statistically significant. Results: The Thl-type cytokine (IFN- r ) was detected in 20(67%) of 30 supernatants from women with URA. In contrast, 2 (20%) of trophoblast-activated PBMC culture supernatants from the 10 parus women with normal reproductive histories was detected IFN- r and but were significantly lower than levels in women with URA who had secreted IFN- r upon trophoblast stimulation (99.80+ 18.17 pg/mL versus 166.47 + 36.96 pg/mL, p<0.05). Spontaneous secretion of IFN- r was significantly higher in culture supernatants from women with URA than in supernatants from women with successful reproductive histories (41.36.09+6.99 pg/mL versus 25.89+9.34 pg/mL, p<0.05). Conclusion: These data indicate that there are significant differences between women with URA and women with normal reproductive histories in their regulation of the Thl-cytokine (IFN- r) in response to trophoblast. Thl-type immunity to trophoblast is associated with URA and may play a role in reproductive failure.

Sesame seeds were roasted for 30, 60, 90, and 120 min at different temperatures (100, 200, and 300℃) and extracted to investigate an adequate condition for producing the high quality sesame oil. Sesame seeds roasted at 200℃ for 90 min gave the high yield of oil. The oil contained the low content of brownish-black precipitates and exhibited an excellent organoleptic quality when judged by descriptive sensory analysis. Thirty one volatile flavor compounds, which are the largest number of volatiles among the oil samples prepared, were identified from the oil sample. The oil contained relatively high concentrations of furfurals (sweet candy-like flavor) and pyrazines (roasted-like flavor), that are considered as good contributors to sesame seed oil flavor, and low concentations of aldehydes (C5∼C10) and ketones, which are considered as bad contributors (oxidized fat-like and painty-like flavors). These results suggest that the roasting condition of 200℃ for 90 min was the best for the oil production in terms of the overall aroma and taste quality under the test conditions.
