Constrictive pericarditis is caused by fibrosis of the pericardium leading to decrease in ventricular compliance. The diagnosis is often delayed due to nonspecific signs and symptoms. The authors experienced eight cases of constrictive pericarditis detected on chest CT scan while being treated for considerable length of time under the clinical impressions of intrathoracic tumor, tuberculous pleural effusion, liver cirrhosis, etc. Constrictive hemodynamics of these patients were confirmed by echocardiogram and cardiac catheterization. Among them five cases were due to tuberculosis. In four cases with pathologically proven tuberculous granuloma, the pericardium was markedly thickened and intensely enhanced. Associated pericardial effusion (n=3), and mediastinal lymphadenitis (n=3) were present, but pericardial calcifications were not seen. On the other hand, the fibrosis group (n=3) displayed mild pericardial thickening. All the three patients showed pericardial calcifications, mild or absent enhancement of pericardium, but no mediastinal lymphadenitis. The cardiovascular changes such as inferior or superior vena caval distension, left ventricular deformity, interventricular septum angulation, and biatrial enlargements were more severe than those in patients with active granuloma. In patients with constrictive pericarditis with nonspecific signs and symptoms, CT scan is very helpful in making the diagnosis and can give informations about the evolution of the disease.

OBJECTIVES: The aims of this study are 1) to determine if GAST is a better indicator in predicting ovarian response to COH compared with patient's age or basal FSH level and 2) to evaluate its role in detecting abnormal ovarian response. DESIGN : Prospective study in 118 patients undergoing IVF-ET using GnRH-a short protocol during May-September 1995. MATERIALS AND METHODS: After blood sampling for basal FSH and estradiol (E2) on cycle day two, 0.5 ml (0.525 mg) GnRH agonist (Suprefact, Hoechst) was injected subcutaneously. Serum E2 was measured 24 hours later. Initial E2 difference (deltaE2) was defined as the change in E2 on day 3 over the baseline day 2 value. Sixteen patients with ovarian cyst or single ovary or incorrect blood collection time were excluded from the analysis. The patients were divided into three groups by deltaE2; group A (n=30):deltaE2<40 pg/ml, group B (n=52): 40 pg/ml< or =deltaE2<100 pg/ml, group C (n=20): deltaE2< or =100 pg/ml. COH was done by GnRH agonist/HMG/hCG and IVF-EF was followed. Ratio of E2 on day of hCG injection over the number of ampules of gonadotropins used (E2hCGday/Amp) was regarded as ovarian responsiveness. Poor ovarian response and overstimulation were defined as E2 hCGday less than 600 pg/ml and greater than 5000 pg/ml, respectively. RESULTS: Mean age (+/-SEM) in group A, B and C were 33.7+/-0.8*, 31.5 +/-0.6 and 30.6+/-0.5*, respectively (*: p<0.05). Mean basal FSH level of group A (11.1+/-1.1 mIU/ml) was significantly higher than those of B (7.4+/- 0.2 mIU/ml) and C (6.8+/-0.4 mIU/ml) 0<0.001). Mean E2hCGday of group A was significantly lower than those of group B or C, i.e., 1402.1+/-187.7 pg/ml, 3153.2+/- 240.0 pg/ml, 4078.8+/-306.4 pg/ml respectively (p<0.0001). The number of ampules of gonadotropins used in group A was significantly greater than those in group B or C: 38.6+/-2.3, 24.2+/-1.1 and 18.5+/-1.0 (p<0.0001). The number of oocytes retrieved in group A was significantly smaller than those in group B or C: 6.4+/-1.1, 15.5+/-1.1 and 18.6+/-1.6, respectively (p<0.0001). By stepwise multiple regression, only deltaE2 showed a significant correlation (r=0.68, p<0.0001) with E2HCGday/Amp, while age or basal FSH level were not significant. Likewise, only deltaE2 correlated significantly with the number of oocytes retrieved (r=0.57, p<0.001). All four patients whose COH was canceled due to poor ovarian response belonged to group A only (Fisher's exact test, p<0.01). Whereas none of 30 patients in group A (0%) had overstimulation, 14 patients among 72 patients (19.4%) in group B and C had overstimulation (Fisher's exact test, p<0.01). CONCLUSIONS: These data suggest that initial E2 difference after GAST may be a better prognostic indicator of ovarian response to COH than age or basal FSH level. Since initial E2 difference demonstrates significant association with abnormal ovarian response such as poor ovarian response necessitating cycle cancellation or overstimulation, GAST may be helpful in monitoring and consultation of patients during COH in IVF-ET cycle.

BACKGROUND: Ultraviolet B (UVB) irradiation can induce apoptosis of melanocytes and melanoma cells. However, mechanism of UVB-induced apoptosis of melanoma cells is not clarified yet. OBJECTIVE: Our purpose was to study the molecular mechanism of UVB-induced apoptosis of melanoma cells. METHODS: G361 lightly pigmented melanoma cells were analyzed for apoptotic mechanism by flow cytometry and western blotting. RESULTS: G361 melanoma cells showed apoptotic features with gradual increment of UVB doses by MTT and flow cytometry. Western blotting disclosed activation of caspase-3 and poly (ADP-ribose) polymerase (PARP) after UVB irradiation. CONCLUSION: In this study, we showed that UVB-induced apoptosis of melanoma cells is mediated by PARP activation which is induced by caspase cascade.

Uterine anomalies have been reported in 4% of women with infertility and in up to 15% of those with recurrent abortion. One of the major intrauterine disorder associated with infertility and recurrent abortions is intrauterine septum, The reproductive outcome of 41 patients of intrauterine septum (7 complete, 34 incomplete) with repeated abortions or infertility was assessed after the uterine septotomy. 5 of 7 patients with comlete uterine septum undergone uterine septotomy (3; hysteroscopic metroplasty, 2; abdominal metroplasty) had total 6 pregnancies and all of them had live biths. 28 patients with incomplete uterine septum got the hysteroscopic intrauterine septotomy and the viable pregnancy rate was 62% (3 ongoing pregnancies, 13 live biths of total 26 pregnancies). 6 patients with incomplete uterine septum had not the operation and 5 patients had 5 live births after total 6 pregnancies with 1 spontaneus abortion. Even though, the number of cases were small, the live birth rate in the group of septotomy of the patients of complete uterine septum (100%, 6/6) was higher than that in the group of not-done (50%, 1/2). The live birth rate in the group of not-done of the patients with incomplete uterine septum (83%, 5/6) was higher than that in the group of hysteroscopic uterine septotomy (62%, 16/26), but 5 of 6 had short uterine septal length (<1 cm), 1 had 1.5 cm septal length in the group of not-done. All the patients with successful pregnancy outcome had no other co-factors at the diagnostic laparoscopy, but the 5 primary infertility patients with no live birth even after treatment (all were with incomplete septum; 3 undergone hysteroscopic septotomy, 2 not-done with one abortion) had other co-factors such as endometriosis, peritoneal or tubal facor. In conclusion, hysteroscopic uterine septotomy would be useful for the patients with habitutal abortion or infertility and more advanced managemnet protocols should be applied to the patients having other co-factors if there was no pregnancy even after the uterine septotomy.

OBJECTIVE: Ovarian hyperstimulation syndrome (OHSS) is one of the well known complication of conttolled ovarian hyperstimulation. Though there have been numerous protocols for the prevention of OHSS, it has not been completely preventable until now. This study was performed to identify clinical predictors for early and late OHSS. METHODS: A retrospective analysis of all IVF cycles in 1993 up to June 1996 was performed. OHSS was diagnosed using the criteria of Rabau modified by Schenker. All cases of OHSS reported in this study presented with marked ovarian enlargement, ascites, oliguria, hemoconcentration and electrolyte disturbance. Ovarian stimulation was carried out using a combination of gonadotrophin releasing hormone-agonist, follicle-stimulation hormone and human menopausal gonadotrophin. 27 patients has moderate or severe OHSS presenting 3-7 days post-human chorionic gonadotrophin (hCG), and 21 patients had severe OHSS presenting 12-17 days post-hCG. RESULTS: No patient with early OHSS went onto develop late OHSS, and no patient with late OHSS had demonstrated early OHSS. Logistic regression showed that early OHSS was predicted by the number of oocytes retrieved and the estradiol concentration on the day hCG injection (P<0.05). Late OHSS was predicted by the transferred embryos, B-hCG on 14 day after hCG injection (P<0.05). CONCLUSION: Early OHSS was an acute effect of the hCG administered prior to egg retrieval in women with high estradiol and large number of retrieved oocytes. Our analysis of the risk factors for early OHSS indicates that cryopreservation of all embryos will not alter the risk of early OHSS even though it should prevent late OHSS. Late OHSS was induced by the rising serum concentration of hCG produced by the early pregnancy, the number of transferred embryos must be adjusted carefully, since it was associated with multiple gestation.

Spinal fluid(CSF) was analyzed in ten pregnant women at term undergoing C-section with spinal anesthesia and in ten non-pregnant women undergoing gynecological operation with spinal anesthesia. The acid-base status, protein and sugar levels in the CSF of the CSF are summarized in Table-2 and Table-3. The pH was slightly higher in the pregnant group compared to that of the non-pregnant controls. The bicarbonate level and the total CO2 content were significantly lower in the pregnant group compared to non-pregnant controls. The protein and sugar level were lower in the pregnant group compared to non-pregnant controls. Acid base changes can markedly affect dissociation of the local anesthetics. More free base will be available for transfer across lipid barriers in a relatively more alkalotic medium which was found in spinal fluid of pregnant women. In addition, lower bicarbonate levels may also affect dissociation of local anesthetic and activity by changing the buffering capacity. In conclusion, our results show that pregnancy induces significant changes in the acid base balance of the spinal fluid. These changes may contribute to the facilitated spread of local anesthetics in both the epidural and subarachnoid spaces.
