        과배란 유도시 내인성 LH surge에 관한 연구

        장준홍(JH Jang),장윤석(YS Chang) 대한산부인과학회 1989 Obstetrics & Gynecology Science Vol.32 No.5

        1. LH surge occured in 38(44.7%) out of 85 cycles studied. 2. Occurence rate of LH surge was not influenced by serum estradiol levels or serum estradiol patterns. 3. Serum LH/FSH ratio on the third day of the menstraul cycle did not significantly after the occurrence rate of LH surge 4. Occurrence rate of LH surge increased significantly as serum progesterone level or rising rate of serum progesterone increased. 5. Number of oocytes retrieved in cycels with LH surge did not differe significantly from those without LH surge. 6. Cleavage rate and pregnancy rate after IVF in cycle with LH surge did not differ significantly from those without LH surge 7. Cleavage rate of oocytes retrieved in cycles with LH surge on the day prior to hCG administration differed significantly from those LH surge on the day of hCG administraion. In conclusion, LH surge occurs in a significantly number of controlled ovarian hyperstimulation cycles with gonadotropins. because the increment of serum progestereone level is followed by LH surge, the rising level of serum progesterone might be used as a predictor of the occurrence of LH surge in cotrolled ovarian hyperstimulation

        정상임신중 양수내 Amylase치 변동에 관한 연구

        장준홍(JH Jang),장윤석(YS Chang) 대한산부인과학회 1980 Obstetrics & Gynecology Science Vol.23 No.11

        There has been known that the fetus is the source of the amylase in amniotic fluid. Amylase activity of amniotic fluid was determined by the modified Caraway method in 26 samples obtained from normal pregnant women admitted to the Seoul National University Hospital during the period from March 1980 to August 1980 in order to elucidate the relationship between amylase activity in amniotic fluid and gestational age and fetal weight. The results obtained were as follows: 1. No amylase activity was detectable in amniotic fluid before or during the 23rd week of pregnancy. 2. A progressive rise in amylase activity of amniotic fluid commencing from the 32nd week was noted, followed by an abrupt increase during the last month of pregnancy. There was significant positive relationship between amylase activity of amniotic fluid and gestational age(r=0.94, P<0.001). 3. Amylase activity of amniotic fluid was also increased as fetal weight increased, and there was a significant positive relationship between amylase activity and fetal weight(r=0.81, P<0.001). 4. The standard value determining fetal maturity was 250 I.U./l of amylase activity in amniotic fluid. 5. Using 250 I.U./l of amylase activity as the standard value for determining fetal maturity(38 weeks or more in gestational age) gave false positive rate of 6 percent and false negative rate of 33 percent. 6. Using 250 I.U./l of amylase activity as the standard value for determining fetal maturity(2,500gm or more in fetal weight) gave false positive rate of 11 percent and false negative rate of 43 percent.

        Meigs Syndrome의 1례

        박상윤(SY Park),장준홍(JH Jang),신희철(HC Shin),장윤석(YS Chang) 대한산부인과학회 1982 Obstetrics & Gynecology Science Vol.25 No.6

        A case of Meigs syndrome is reported with the brief review of literature. This case, 23-year old nullipara, was referred to our hospital because of ahortness of breath and rapidly growig palpable mass in the lower abdomen. the massive hydrothorax showed in her chest film. The laparotomy and histopathological study revealed 19*11*7cm in sized stoney hard left ovarian tumor of fibroma. After removal of the tumor, ascites and hydrothorax had been completely subsided within 7 days.

        임신에 합병된 갈색세포종의 1예

        윤도현(DH Yoon),안덕호(DH Ahn),장준홍(JH Jang),박상윤(SY Park),이효표(HP Lee) 대한산부인과학회 1982 Obstetrics & Gynecology Science Vol.25 No.10

        저자들은 서울대학교 병원 산부인과에서 임신에 합병된 갈색세포종의 1예를 치험하였기에 증례보고와 함께 간단한 문헌적 고찰을 하였다. Pheochromocytoma is a rare complication of pregnancy and poses a serious threat to the wellbeing of the mother and fetus. The mortality rate is significantly low if the tumor is detected prior to term. But it seems to be that too many cases still go unreconized because of close similarity between pheochromocytoma and toxemia. A case of pregnancy complicated by pheochromocytoma in 22-year old woman is reported with review of literatures.

        자궁내막간질선근종증 1 례

        박봉림(BL Park),김관옥(KO Kim),김규관(KG Kim),박건남(KN Park),장준홍(JH Jang),김동진(DJ Kim) 대한산부인과학회 1987 Obstetrics & Gynecology Science Vol.30 No.9

        저자들은 본병원 산부인과에서 30세의 경산부에서 자궁간질선근종증 1례를 체험하였기에 문헌고찰과 함께 보고하는 바이다. Endolymphatic stromal myosis of the uterus is a unusual mensenchymal tumor, originating in the endometrium. There has been considerable controversy as to nomenclature because of the uncertainty of the cell of origin and the behavior of the tumor. Here a case of a 30-year old woman with a endolymphatic stromal myosis is presented with a review of literatures.
