Nutrikinetic study of fermented soybean paste (Cheonggukjang) isoflavones according to the Sasang typology

BACKGROUND/OBJECTIVES: In Oriental medicine, certain foods may be beneficial or detrimental based on an individual's constitution; however, the scientific basis for this theory is insufficient. The purpose of this study was to investigate the effect of body constitution, based on the Sasang type of Korean traditional medical classification system, on the bioavailability of soy isoflavones of Cheonggukjang, a quick-fermented soybean paste.SUBJECTS/METHODS: A pilot study was conducted on 48 healthy Korean men to evaluate the bioavailability of isoflavone after ingestion of food based on constitution types classified by the Sasang typology. The participants were classified into the Taeeumin (TE; n = 15), Soyangin (SY; n = 15), and Soeumin (SE; n = 18) groups. Each participant ingested 50 g of Cheonggukjang per 60 kg body weight. Thereafter, blood was collected, and the soy isoflavone metabolites were analyzed by ultra-performance liquid chromatography/quadrupole time-of-flight mass spectrometry. Ntrikinetic analysis of individual isoflavone-derived metabolites was performed.RESULTS: Our nutrikinetic analysis identified 21 metabolites derived from isoflavones in the blood samples from 48 healthy Korean men (age range, 21-29 years). Significant differences were observed in the time to maximum concentration (T(max)) and elimination half-life (t(1/2)) for nine metabolites among the three groups. The T(max) and t(1/2) of the nine metabolites were higher in the SE group than in the other groups. Moreover, the absorption rates, as determined by the area under the plasma-level curve (AUC) values of intact isoflavone, were 5.3 and 9.4 times higher in the TE group than in the SY and SE groups, respectively. Additionally, the highest AUC values for phase I and II metabolites were observed in the TE group.CONCLUSIONS: These findings indicate that isoflavone bioavailability, following Cheonggukjang insgestion, is high in individuals with the TE constitution, and relatively lower in those with the SE and SY constitutions.

Ultrasonographic factors related with prediction of delivery day in term singleton pregnancy / 대한산부인과학회지

OBJECTIVE: The aim of this study was to find out the relating factors with the actual delivery day in term singleton pregnancy. METHODS: The 52 patients with singleton gestation were visited weekly and measured for their lower uterine segment (LUS) thickness, cervical length and cervical gland thickness by transvaginal ultrasonography and for amnionic fluid index (AFI) by transabdominal ultrasonography from 36 weeks of gestation until birth. Regression analysis was used to find out the relevance between these factors and remaining days to birth. RESULTS: There was a significant relationship between cervical length and remaining days to birth in term pregnancy, which could be described as a mathematical equation (remaining days for delivery = 6.12 + 0.24 x cervical length (mm) r=0.29, p<0.01). However, no relationship was found between factors such as LUS, AFI, and cervical gland thickness and remaining days to birth. CONCLUSION: Our results suggest that the actual delivery day in term singleton pregnancy might be predicted with cervical length.

The Weaning Method of inhaled Nitric Oxide

PURPOSE: inhaled nitric oxide(iNO) is an excellent method for the postoperative pulmonary hypertension in congenital heart disease. But more detailed care is needed because of the development of rebound pulmonary hypertension after NO Withdrawal. We performed this study in order to discontinue the iNO successfully by way of presenting the adequate weaning and supplying methods. METHODS: Between January, 1998 and August, 1999 we sudied 10 patients who had rebound pulmonary hypertension(RPH) after iNO withdrawal. We completed the iNO in these patween the first the second trial of the weaning process. We tried to discover the differences between the first and second weaning process. We measured NO concentration at the start and just before NO withdrawal and during the period of weaning process. Moreover, to identify the iNO effects during the weaning of the iNO, we counted the degree of the change of PaO2/FiO2and mean PAP/SAP beween initial and at half of the initial NO concentration. RESULTS: Second weaning had a longer duration weaning process(11+/-0 cersus 5+/- hours, P<0.05), lower NO concentration just before NO withdrawal(2+/-.6 versus 4+/-ppm, P<0.05). In the change of the mean PAP/SAP and PaO2/FiO2as iNO was weaning from the initial iNO concentration to a half of the initial iNO concentration, the degree of increase in mean PAP/SAP(0.026+/-.07 versus 0.054+/-.07, P<0.05) and the degree of decrease in PaO2/FiO2(49+/-4 versus 65+/-2, P<0.05) were smaller in the second in the second weaning process than the first weaning process. CONCLUSION: A successful weaning of iNO can be performed with a low iNO concentration at the start and just before withdrawal and with the long duration iNO weaning process. Moreover, We speculate that the degree of change in the mean PAP/SAP and PaO2/FiO2at the half of the iNO weaning process are an indicator for the development of RPH.

Three cases of symphysis pubis separation associated with delivery / 영남의대학술지

Symphysis pubis separation is an uncommon but not rare complication of delivery. Characteristic symptoms of symphyseal separation include suprapubic pain and tenderness which radiate to the back or legs, difficult ambulation, and bladder dysfunction. Clinical history, presenting symptoms, and response to therapy are sufficient to make the diagnosis, although radiographic documentation of symphyseal separation by x-ray or ultrasound are frequently used to confirm the diagnosis. The underlying etiology of symptomatic symphyseal separation has not been fully elucidated. Associations with macrosomia, pathological joint loosening, and increased force placed on the pelvic ring have been suggested as possible etiologies. Conservative therapy, including bed rest, pelvic binders, ambulation devices, and mild analgesics usually result in complete recovery within 4-16 weeks. Our experience of three cases of peripartum symphysis pubis separation delivered from 1998 to 1999 were reviewed with related articles.

Telomerase Activity in Cervical Cancer / 대한산부인과학회잡지

OBJECTIVE: Telomerase is a ribonucleoprotein that synthesizes TTAGGG repeats onto chromosome ends. The expression of telomerase is thought to be required for cellular immortality and carcinogenesis. This study was conducted to examine the telomerase activation occurs in cervical carcinogenesis. METHODS: The standard telomeric repeat amplification protocol(TRAP) was used to examine telomerase activity in tissues of 10 normal cervix, 10 carcinoma in situ, and 21 invasive cervical carcinoma. RESULTS: Telomerase activity was detected in tissues of 16/21(76.2%) invasive carcinoma, in 5/10(50.0%) carcinoma in situ, and in 3/10(30.0%) normal cervix. But the degree of telomerase activity in normal cervix was weak. There was significant difference in 3 groups(p<0.05). The results of neoadjuvant chemotherapy in 10 invasive cervical carcinoma were as follows. In 8 cases of which tumor size decreased more than 50%, 5 were positive for telomerase. In 2 cases that didn't respond to chemotherapy by tumor size, 1 was positive for telomerase. There was no significant difference between 2 groups. All of the 5 cases that had pelvic lymph node metastasis revealed positive telomerase activity, and the 11 cases of 16 cases that didn't have pelvic lymph node metastasis were positive for telomerase, but there was no significant difference in 2 groups. The positivity of telomerase activity in clinical stage of invasive cervical carcinoma was 73.3% in stage I(11/15), 75.0% in stage II(3/4), 100% in stage III(1/1), and 100% in stage IV(1/1), but there was no significant difference in each stages. CONCLUSION: Telomerase seems to be uniquely associated with malignant transformation of cervix and can be used as a tumor marker. Additional studies are needed to better clarify the biological significance of telomerase expression in cervical tumorigenesis.

Inhalation Anesthesia with High Frequency Jet Ventilation / 대한마취과학회지

High frequency jet ventilation(HFJV) induces adequate gas exchange with tidal volume smaller than that of other conventional ventilation method. In critically ill patients, HFJV reduces the unwanted hemodynamic effects of conventional ventilation caused by the increase in intrathoracic pressure. But general anesthesia with jet ventilator has been dependent only on intravenous anesthetics. Therefore, this study was done to administer inhalation anesthetics(N2O, enflurane) during HFJV. This study was carried out from June 1992 to January 1993 in the 64 operated patients who beIonged to ASA class I, II in Chung Ang University Hospital The 22 patients using conventional ventilation were control group and the other 42 patients who had inhalation anesthesia by using HFJV were experimental group. In all patients, blood pressure and heart rate were checked on preinduction, postinductive 0, 5, 10, 15, 20, and 30 minutes. The result were as follows I) Systolic blood pressure was increased just on postinduction in both groups(P<0.05). It was decreased from postinductive 5 minutes to 30 minutes in control group, but there was no change in experimental group(P<0.05). 2) Diastolic blood pressure was increaeed just on postinduction in both groups(P<0.05). But it was increased from postinductive 5 minutes to 30 minutes in experimental group(P<0.05). 3) Mean blood pressure was increased just on postinduction in both groups(P<0.05). It was increased from postinductive 5 minutes to 15 minutes in control group and from postinductive 5 minutes to 30 minutes in experimental group(P<0.05). 4) Heart rate was increased just on postinduction and postinductive 5 minutes in control groupg <0.05), and increased from postinductive 0 minute to postinductive 30 minutes in experimental group(P<0.05). 5) pH was increased on postinductive 30 minutes compared to that of preinduction in both groups(P <0.05). 6) PaCO2 was more decreased on postinductive 30 minutes than preinduction in both groups (P<0.05), but there was no clinical significance. And PaO2 was increased at postinductive 30 minutes(P<0.05), which resulted from the increase of FiO2. As above results, inhalation anesthesia with HFJV is supposed to be useful if the difficulty of controlling the concentration of inhalation anesthetics and the contamination of operating room by expelled inhalation anesthetics were solved.
