This study was performed to identify the effect of the hydrosalpinx fluid on sperm motility. It has been reported that the patients with hydrosalpinx show the outstandingly lower success rate than other patients having infertility by different factors. It is unclear that the cause of it is influenced by hydrosalpinx fluid directly or by secondary chronic inflammation of endometrium. We wanted to know if the hydrosalpinx fluid influences sperm motility parameters directly such that it is related to the development of infertility. Therefore, using computer assisted semen analyzer (CASA), we observed, from February to July, 1997, how sperm motility, sperm progressive motility, sperm curvilinear velocity, sperm lateral head displacement, sperm straightness and sperm linearity change after treating normal sperm with hydrosalpinx fluid to evaluate sperm function on infertility. The result was that the study group (n=32) has the tendency to differ from the control group (n=32) on sperm motility, progressive motility, curvilinear velocity, lateral head displacement, straightness and linearity. We concluded that the hydrosalpinx fluid, with varying degree, directly has the harmful effects on sperm motility parameters, that is, curvilinear velocity, lateral head displacement and linearity of sperm which are related to the hyperactivation, hence decreased capacitation.

OBJECTIVE: To evaluate the efficacy of low dose gonadotropin releasing hormone agonist(GnRH-a) therapy combined with high dose human menopausal gonadotrpin(hMG) following estrogen & progesteron therapy for poor responders. METHODS: From May 1997 to Feb 1999, 36 patients who were defined as poor responders on previous consecutive two and more superovulation cycles were randomly allocated to lowdose GnRH-a short protocol with high dose hMG protocol pretreated with estrogen & progesterone(E/P therapy)(n=16)(study group) and the clomiphene citrate with hMG(n=20)(control group). All patients were planned to undergone in-vitro- fertilization(IVF) and embryo transfer(ET) after controlled ovarian hyperstimulation(COH). RESULTS: Two groups were similar with respect to clinical features and basal FSH and E2 levels. The mean level of E2 on day 5, 304.3+/-148.ng/ml in study group was significantly higher than that in control group, 182+/-34.9ng/ml. The mean levels of E2 on hCG day was also significantly higher in study group than control group(1324+/-320ng/ml, vs 414+/-168ng/ml). The mean day of hCG day in study group, 12.3+/-0.3 was shorter than that in control group, 13.8+/-0.4. The concellation rates of cycles were significantly lower in study group than control group(13.2% vs 84.2%). But clinical pregnancy rates did not showed the significant difference between two groups. CONCLUSION: The study suggested that a lowdose GnRH-a short protocol with high dose hMG pretreated with estrogen & progesterone can improve the ovarian response in poor responder group.

To objectively compare the response of the palliative radiotherapy in bone metastatic patients which decreases pain and prevents pathologic fractures, we introduced and applied the RTOG pain and narcotic measure system. From Oct in 1991 to July in 1993, thirty-two patients with painful bone metastases, 17 of them were solitary lesions and others were multiple lesions, were treated with mainly 6 MV photon otherwise 15 MV photon. Radiation doses to bone metastatic sites ranged about from 2000 to 4600cGy. Responses of radiation therapy were compared with days of pre-RT, RT finish, 3, 6, 9 months after the start of RT and solitary versus multiple lesions and follow up scores according to the RTOG measure system. Survival analysis was done. Pain and narcotic score of the entire patients were 7.3, 7.8 at the pre-RT period and 2.6, 3.9 at the immediate or 2 weeks after RT, which was 64%, 50% decrement compared with the pre-RT score. Pain scores of 3, 6 and 9 months after the beginning of irradiation were 3.6, 3.7 and 3.3. The best response found in the breast and prostate primaries was 84%, 78% decrement of pain score as compared with pre-RT score (statistically insignificant). Median survival was 5.5 months and mean survival was 5 months. We conclude that the RTOG pain and narcotic measure system in relatively effective scale in the comparison of before and after palliative irradiation to the painful bone metastatic sites but more detailed parameters will be required in the narcotic scoring system. More aggressive but less or similar toxic radiotherapy is needed in the patients having relatively long life expected time.

PURPOSE: The aim of this study is to analyze the interaction system between instructor and learners and strive for class improvement based on the evaluation. METHODS: Flanders Interaction Analysis System classifies instructor and learner's speaking into ten items. Observer analyzed every verbal interaction in class and filled out classified table recording the number of adequate category every three seconds. RESULTS: In this study, observed class spent 94.3% of time on teaching and learning activities. So it could be said that the class used time effectively without any waste. The instructor showed indirect teaching method and as a result, the students showed more initiative statements than simply answering questions. The major pattern was question--> answering questions, and incidental pattern was lecture--> initiative statement--> silence or disorder--> initiative statement--> lecture. CONCLUSION: In medical education, small group lesson is one of the popular teaching methods where Flanders interaction can be analyzed effectively. Using such evaluation, we can promote better teaching and learning.

OBJECTIVE: Proteinuria is a major clinical manifestation as well as hypertension and generalized edema in pregnancy-induced hypertension(PIH) and it should be considered an important marker of perinatal outcome. We studied the impact of proteinuria on maternal and perinatal outcome according to the degree of urine protein in PIH. METHODS: Maternal urine protein and serum albumin levels were studied in 64 cases of PIH who were admitted to Department of Obstetrics and Gynecology, Pil-Dong Hospital, College of Medicine, Chung-Ang University for the period of 10 years from January 1, 1989 to December 31, 1998. RESULTS: Serum albumin level was 2.9+/-0.7g/dL in mild preeclampsia group and 2.7+/-0.7g/dL in severe peeclampsia group and there was a significant difference between them. Birth weight of infant was 3001+/-659g in mild preeclampsia group and 2446+/-878g in severe peeclampsia group, and there was a significant difference between them. 1 minute Apgar score was 8.4+/-2.4 and 7.6+/-3.4, respectively and there was a significant difference between them. 5 minute Apgar score was 9.5+/-1.8 and 8.4+/-2.9, respectively and there was a significant difference between them. There were several maternal complications above 2(+) urine protein and no maternal complications below 1(+) urine protein. Small for gestational age infant was more common above 2(+) urine protein than below 1(+) urine protein and fetal death was more common in 3(+) urine protein. CONCLUSIONS: There was a decreasing trend in gestational weeks at delivery as proteinuria become more severe and also in birth weight, 1 minute Apgar score and 5 minute Apgar score. Maternal and fetal complications were more common as proteinuria become more severe.
