OBJECTIVES: The objectives of this study is to compare the differences of fetal heart rate (FHR) variables between preterm and term pregnancies after acoustic stimulation using computerized analysis of fetal heart rate. METHODS: Eighty-two normal pre-term and term pregnancies entered to this study after conventional 20-minutes nonstress test(NST) and 10-minutes acoustic stimulation test (AST). Acoustic stimulations were performed using Fetal Acoustic Stimulator (Model 146, Corometrics, US). We analyzed the FHR response after acoustic stimulation using our on-line computerized FHR analysis system, HYFM-I & II software. The changes of loss of signal, baseline FHR, variability, number of fetal movements, and number of FHR accelerations were analyzed numerically. RESULT: The mean baseline FHR was increased in term pregnancies from 141+/-7.0bpm to 152.7+/-9.7bpm, and in preterm pregnancies from 144.6+/-6.8bpm to 156.8+/-10.2bpm, respectively. The mean baseline FHR was significantly increased in both term and preterm pregnancies (p<0.01. paired t-test). The variability of FHR was increased in term pregnancies from 18.2+/-6.4bpm to 22.6+/-5.0bpm and in preterm pregnancies from 17.8+/-5.5bpm to 22.7+/-5.9bpm, respectively. The variability of FHR was also significantly increased in both term and preterm pregnancies. (p<0.01. paired t-test) CONCLUSION: The mean baseline FHR and the variability of FHR was significantly increased both preterm and term pregnancies. But the difference of each FHR variables between preterm pregnancies and term pregnancies was not statistically significant in this study.

BACKGROUND: It has been reported that Cortex mori ( Morus alba L, Sangbaikpi ; CM ), the root bark of mulberry tree, plays a role in inhibiting mast cell activation. Human seminal plasma ( HSP ) modulates immune systems and activates rat peritoneal mast cells ( RPMC ). However, the inhibitory agents of HSP - induced mast cell activation have not been disclosed yet. OBJECTIVE AND METHOD: This study was undertaken to determine the effects of CM on HSP-induced mast cell activation by morphologic and functional methods. Morphological changes of RPMC by HSP alone or CM plus HSP were observed with the inverted light microscope. And the amounts of histamine and calcium were measured by radioisotopic enzymatic histamine and radioisotopic calcium assays. RESULTS: By inverted microscopy, HSP-induced RPMC degranulation occurred in a dose-dependent fashion. After pretreatment of RPMC with CM, there was no HSP-induced degranulation. Degranulation index (DI) of RPMC treated with Hanks balanced salt solution (HBSS), CM or HSP was 7.0+/-4.3, 9.0+/-6.2, 56.5+/-16.9, respectively. After pretreatment of RPMC with CM, HSP-induced DI was 11.0 +/-7.1. These results indicate that CM inhibited HSP-induced degranulation of RPMC. HSP-induced RPMC histamine release (HR) was dose-dependent. HR of RPMC treated with HBSS, CM or HSP was 0.18+/-0.10, 0.30+/-0.19, 4.48+/-0.86 ug/ml, respectively. After pretreatment of RPMC with CM, HSP-induced HR was 0.52+/-0.21 ug/ml. These results indicate that CM inhibited HSP-induced HR from RPMC. Intracellular calcium level ( ICL) of RPMC was also increased according to the concentration of HSP. ICL of RPMC treated with HBSS, CM or HSP was 6.1+/-1.0, 9.0+/-2.1, 30.2+/-6.5 pmole, respectively. After pretreatment of RPMC with CM, HSP-induced ICL of RPMC was 11.6 +/- 3.3 pmole. These results indicate that CM inhibited HSP-induced calcium uptake of RPMC. CONCLUSION: From these results, it is suggested that CM contains some substances which inhi-

Choriocarcinoma associated with a normal pregnancy is rare. Futhermore, choriocarcinoma coexistent with a viable pregnancy is even rarer and associated with a greater risk of hepatic and cerebral involvement. So timely diagnosis of the disease is important for successful treatment and aggressive diagnostic procedures may therefore warranted. The patient should be treated with primary intensive combination chemotherapy(EMA-CO) and the selective use of irradiation and surgical therapy. We experienced a case of metastatic choriocarcinoma of lung and kidney following preterm delivery at 34th week of pregnancy and so present it with brief review of literature.

Meigs' syndrome is a benign ovarian tumor associated with ascites and pleural effusion. Elevated cancer antigen 125 (CA-125) in Meigs' syndrome is an unusual clinical condition reported in few cases. We report here on a 61-year-old woman who presented with dyspnea; in imaging assessment, a heterogeneous pelvic mass measuring 12 x 11 cm with ascitic fluid was reported. Pleural effusion was detected on Chest X-ray. Aspiration of pleural fluid showed no evidence of malignancy. CA-125 level was 347 IU/mL. The patient underwent laparotomy during which a mass measuring 12 x 11 cm was detected in her left adnexa. Histology showed ovarian thecoma. The mass was resected, and, after that, the symptoms disappeared and CA-125 level reached 19 IU/mL. The patient had experienced no problem after 12 months of follow up. Although postmenopausal women with ovarian tumor, ascites, pleural effusion, and elevation of CA-125 levels probably have malignant ovarian tumors, Meigs' syndrome must be considered in the differential diagnosis.

The recent introduction of chemotherapy in the treatment of the gynecologic malignancies has gained wide acceptance along with preoperative and postoperative adjuvant therapy and with preradiation and concurrent chemoradiaton therapy. But, the side effects of chemotherapy including bleeding and infection due to bone marrow suppression have resulted in increased morbidity and mortality of the patients and delayed treatment and a reduction in the chemotherapeutic agents used. In spite of the development of antibiotics and the supportive care of infection, sustained leukopenia in the patients during chemotherapy accounts for the high mortality rate due to sepsis. The early detection of the leukopenia during chemotherapy may enable clinicians to overcome infection problems by timely use of prophylactic broad spectrum antibiotics and G-CSF or GM-CSF. The author investigated the grade, duration, time of onset and other clinical features of the leukopenia and the effects of the age (> or =60 years vs <60 years), the number of the cycle of chemotherapy (> or =3 cycles vs < 3 cycles), fever and performance scale on the leukopenia. 79 cases (32 patients) of the leukopenia during chemotherapy of various gynecologic malignancies at the Department of Obstetrics and Gynecology at Hanyang University between January, 1996 and December, 1998 entered to this study. The results were as follows; 1. Leukopenia occurred at 14.2+/-6.1 day from the first day of chemotherapy, 2. The duration of leukopenia was 2.5+/-1.6 days 3. No significant difference was found between eldely patients ( > or =60 years, n=13) and younger patients ( <60 years, n=66) about the severity, duration and time of onset of leukopenia. 4. No significant difference was found between the patients with more than 3 cycles of chemotherapy (n=40) and less than 3 cycles (n=39) about the severity, duration and time of onset of leukopenia. 5. Febrile leukopenic cases (n=6) had significantly lower granulocyte count, longer leukopenic period and earlier onset of leukopenia than afebrile (n=73). 6. It is thought that performance status scale does not affect the grade of leukopenia, onset of leukopenia and the leukopenic period.

Epithelioid trophoblastic tumor (ETT) is a rare gestational trophoblastic neoplasm composed of intermediate trophoblasts. Most cases of ETT are reported in women of reproductive age following a prior gestation within 2 weeks to 30 years. ETT is extremely rare in postmenopausal women. It is commonly misdiagnosed as a poorly differentiated carcinoma or another type of gestational trophoblastic tumor. We report a case of ETT in a 56-year-old woman that developed 23 years after the patient's last pregnancy.
