Uterine serosal pregnancy is an extremely rare form of ectopic pregnancy. This is a report of a 35-year-old primigravida woman who was diagnosed with uterine serosal pregnancy via laparoscopic intervention. A 35-year-old woman (gravida 1, para 0) was referred from a local clinic for a ruptured left tubal pregnancy at amenorrhea 5+0 weeks with elevated serum beta human chorionic gonadotropin (16,618 mIU/mL). A pregnancy on the left posterior wall of the uterine serosa was diagnosed during the operation and successfully treated with laparoscopic surgery as a conservative management strategy to enable fertility preservation. With the advantages of ultrasonography and laparoscopy, an early diagnosis of a primary abdominal pregnancy located on the left posterior wall of the uterine serosa was made, prior to the occurrence of severe intra-abdominal massive hemorrhage, which was then treated laparoscopically as a conservative management strategy enabling the preservation of fertility.

Abdominal ectopic pregnancy has been reported to occur in approximately 1% of overall patients diagnosed with ectopic pregnancy. Definite diagnosis of abdominal pregnancy by using image study is limited. Early diagnosis is often delayed, which result in high maternal morbidity and mortality due to massive bleeding. Therefore, diagnostic surgical intervention should be generally considered as a first-line if there is any sign suspected for abdominal ectopic pregnancy. Uterine serosal pregnancy is extremely rare form of abdominal ectopic pregnancy. Exact mechanism of uterine serosal pregnancy is also not well defined, and only few cases were reported so far. Here, we report a case of 35-year-old primigravidarum who diagnosed with uterine serosal pregnancy via laparoscopic intervention. The patient was referred from local clinic for ruptured left tubal pregnancy at amenorrhea 5+0 weeks with elevated serum beta human chorionic gonadotropin (b-hCG) level (16,618mIU/mL). Transvaginal sonography revealed 1.8 cm sized mass located adjacent to the left cornus with certain amount of hemoperitoneum. With the preoperative impression of left cornual pregnancy with ruptured status, the patient was underwent emergent diagnostic laparoscopy. Entering the abdominal cavity, about 300 mL hemoperitoneum was noted, and 2x2cm-sized ruptured ectopic mass was dangling from the left posterior wall of uterine serosa, causing active bleeding. Both adnexae and other pelvic organ were grossly normal. The ectopic mass was successfully removed and the uterine scar was meticulous sutured. The pathologic reports confirmed the ectopic pregnancy. The patient's postoperative course was uneventful and the level of serum b-hCG gradually decreased within normal range. (1429 mIU/mL at POD 7, 79.47 mIU/mL at POD 14, and 4.87 mIU/mL at POD 28.

( Hee Jung Park ),( Mi Young Baek ),( Jin Gyeong Cho ),( Kyeong Hwa Seo ),( Gee Young Lee ),( Sun Ju Moon ),( Eun Mi Ahn ),( Nam In Baek ) 한국응용생명화학회 2011 Applied Biological Chemistry (Appl Biol Chem) Vol.54 No.3

Tubers of Corydalis turtschaninovii were extracted with 80% aqueous methanol (MeOH), and the concentrated extract was successively partitioned with n-hexane, ethyl acetate (EtOAc), butanol (n-BuOH), and H2O. An activity-guided fractionation to search for insecticidal compounds against aphids led to the isolation of six alkaloids from the n-hexane and EtOAc fractions using a repeated silica gel, an octadecyl silica gel (ODS), and Sephadex LH-20 column chromatographic separations. Based on the spectroscopic data of NMR, mass spectroscopy (MS), and IR, the chemical structures of the compounds were determined to be: (+)-stylopine (1), (+)-corydaline (2), demethylcorydalmine (3), isocorypalmine (4), glaucine (5), and pseudoprotopine (6). These compounds showed significant insecticidal effects against Aphis gossypii, 69.7±7.2, 46.9±2.4, 68.5±8.6, 75.5±4.2, 80.2±9.7, and 78.9±11.3% at 1,000 ppm, respectively.

Dye-sensitized solar cell(DSC) is composed of a dye-adsorbed nanoporous TiO₂ layer on fluorine-doped tin oxide(FTO) glass substrate, electrolyte, and platinium doped counter electrode. Among these, a dye-absorbed nanoporous TiO₂ layer plays an important role in the performance of the DSC because the injected electrons from excited dye molecules move through this layer. And the condition of TiO₂ layer such as the morphology and thickness affects on the electron movement. Therefore, the performances and the efficiency of DSC change as the thickness of TiO₂ layer is different. Electrochemical Impedance Spectroscopy(EIS) is the powerful analysis method to study the kinetics of electrochemical and photoelectrochemical processes occurring in the DSC especially the injected electron movements. So we analyzed the DSCs with different TiO₂ thicknesses by using EIS to understand the influence of the TiO₂ thickness to the performance of the DSC clearly. Finally, we got the EIS analysis on the DSC with different TiO₂ thickness from the internal resistance of the DSC, the electron life time and the amount of dye molecules.

The purpose of this study is to determine the factors affecting the start time of early adaptation of infants, such as individual characteristics of infants(age, gender), family characteristics(having a brother or not, employment of mothers), and characteristics of early childhood education institutions(whether or not funding, institution type) Is to observe whether it is related to the survival analysis for 20 weeks. The subjects of this study were 244 infants at 4 early childhood educational institutions in Jeollabuk-do. Early adaptation behaviors of infants were recorded in the "Initial Adaptation Behavior List Observation Record" for 20 weeks from admission, and a questionnaire about infant background variables was used as data for survival analysis. As a result of the study, as observed for 20 weeks, 238(97.5%) of the total 244 infants were adapted. As an early adaptation pattern of infants, 54%(111 infants) of infants adjusted after 6 weeks. In the personal characteristics variable according to the initial adaptation of infants, 3 to 6 (2.5%) children by age group misadapted, 5 males and 1 female female. In the family characteristic variable, there was a significant difference in the early adaptation of infants according to the presence of siblings and the mother's employment. In the characteristics of early childhood education institutions, there were significant differences in the early adaptation of infants according to funding status and institution type. The results of this study show that the early adaptation patterns of infants were observed for 20 weeks and the relationship of initial adaptation according to individual characteristics, family characteristics, and early childhood education institution characteristics was applied to the survival analysis to study the changes in infants' initial adaptation. It is significant in that. Based on the main research results, the patterns of early adaptation and implications for the relationship between early adaptation and background variables were discussed, and limitations of the study and suggestions for subsequent studies were presented.
