To elucidate the funcion of arachidonic acid as a secondary brain edema facotr, the infusion edema model was constucted using adult cats with studies of somatosensory evoked potentials, regional cerebral blood flow of white matters, brain water contents, magentic resonance images and histological findings. Among 50 cats, 6 cats were used as sham poerated group without infustion and in 45 cats solutions of various concentrations of arachidonic acid and physiologic saline were infused into the left and right frontal white maters respectively. According to the different concentrations of arachidonic acid, three groups were named as group A(0.1mg/ml), group B(1mg/ml), group C(10mg/ml). During 4 hours of slow infusion of the infusates(average 0.5ml in each side totally) central conduction time(CCT) was measured every an hour with contralateral median nerve stimulation bilaterally and cerebral blood flow(CBF) of white matter was measured by hydrogen clearance method every 2 hours. Finally the cats were sacrificed and specimens of edematous white matter obtained bilaterally at the coresponding points. Water contents were measured with vacuum freeze drying method. T2-weighted magnectic resonance images(MRI) and light microscopic studies were performed in a cat of each groups. The results were as followed ; 1) MRI and histologic findings showed that the infusion brain edema technique was efective in inducing interstitial edema, but the differences in the degree of edema formation between the right and the left sides were not siginificant in all groups. 2) There were no statistically significant difference between the water contents of the right and that of left in all groups. 3) Either infusion of arachidonic acid or physiologic saline in the white matter did not change regional white matter CBF in all groups. 4) The I-N1 interpeak latency was labelled as central conduction time(CT), and the baseline CCT was 5.83+/-0.52msec. 5) The differences of CCT between infusion group and noninfusion group were statistically significant in group C at 2, 3, 4hours(p>0.01) and the differerences of cct between arachidonic acid and physiologic saline infustion sites were statistically significant in group B at 4 hors, group C at 1 hour(p>0.05) and group C at 2, 3, 4hours(p>0.01) after eginning of infusion and the differences increased with time in group C(p>0.01). The results indicate that arachidonic acid does not have edemogenic properties during 4 hours infusion but may induce neurologic dysfunction as to increase the CCT in somatosensory evoked potential studies if it exists in the edema fluid of brain white matter.

OBJECTIVE: To assess the outcomes of pregnancies in women with kyphoscoliosis. METHOD: A total of 15 patients (17 pregnancies) complicated by kyphoscoliosis were reviewed among 19,717 deliveries between Jan. 1991 and Apr. 2001, from the Department of Obstetrics and Gynecology, Seoul National University Hospital. Their prenatal course, mode of deliveries, and pregnancy outcomes were scrutinizingly investigated. RESULTS: The incidence of kyphoscoliosis in this study was one per 1160 deliveries. The mean age of these patients in their pregnancies was 30.6+/-4.4 years (range 23-38), mean height 143.5+/-14.0 cm (range 124-160), and mean weight 55.8+/-14.4 kg (range 38-96). The causes of kyphoscoliosis included idiopathic (n=8), spinal tuberculosis (n=3), external trauma (n=3), poliomyelitis (n=1), spinal muscular atrophy (n=1), and progressive muscular dystrophy (n=1). The mean forced vital capacity (FVC) was 2.098+/-0.774 L (range 0.54-3.59) and mean vital capacity (VC) % predicted was 68.2+/-20.6% (range 24-105) prior to delivery. Vaginal delivery was performed in 4 cases, and cesarean section in 13. Fetal growth restriction was identified in 7 cases, and one case had both fetal heart anomaly and imperforate anus. Two babies were managed in neonatal intensive care unit; preterm birth at 34 weeks in one case, and term birth with low apgar score in the other. Maternal pulmonary complication was developed in two cases, the lowest two values of FVC and VC % predicted, one was FVC 0.86 L, VC % predicted 33% and the other was FVC 0.54L, VC % predicted 24%. These mothers were managed with transnasal oxygen therapy in one, artificial oxygen therapy in the other. CONCLUSION: The maternal and perinatal risks in pregnancy associated with kyphoscoliosis may be dependent on maternal pulmonary function prior to delivery.

Suprasellar cistern is uncommon location where the arachnoid cysts involve and only sporadic case reports are seen in the world literature. A case of suprasellar arachnoid cyst is reported, which mimicked such clinically common perisellar lesions as pituitary adenoma, empty sellar syndrome, dermoid cysts, etc., and could be differentiated from them preoperatively with C.T. scan and pneumoencephalography.

Lobectomy with mediastinal node dissection has been standard treatment for non-small cell lung cancer (NSCLC). Nowadays, video-assisted thoracoscopic surgery (VATS) is gaining acceptance as an alternative treatment option, given the quality-of-life benefits that it confers. For the VATS procedure, most surgeons create two or three ports with a utility incision of 3 to 5 cm. However, with acquired skill and instrumentation advances, single-incision thoracoscopic surgery has emerged over time. Here, we report the case of an 86-year-old female with NSCLC treated by single-incision segmentectomy.

Strumal carcinoid of ovary is an unusual form of monodermal ovarian teratoma with thyroid-like follicles admixed with typical carcinoid tumor pattern. Most of them arise in dermoid cyst or in mature solid teratoma. Recently we experienced a case of strumal carcinoid postoperatively and report this case with a brief review of the concerned literatures.

OBJECTIVE: This study was done to formulate Korean fetal biometry charts of midtrimester presenting percentile values as a function of gestational age. METHODS: The relationships between the ultrasound measurement of 5 fetal parameters (biparietal diameter, head circumference, abdominal circumference, femur length, transverse cerebellar diameter) and nuchal skinfold thickness and menstrual age were determined by a cross-sectional study. The study group consisted of 215 normal healthy pregnant Korean women with known last menstrual period and regular menstrual period who had been performed genetic amniocentesis at our hospital and for whom complete pregnancy outcome information was available. All ultrasound examination was performed by one expert examiner. For each of the 5 parameters, the 5th, 10th, 25th, 50th, 75th, 90th, and 95th percentiles were determined. RESULTS: Ready-to-use fetal measurement charts in midtrimester are presented in a format giving the percentile values as a function of gestational age. CONCLUSION: These fetal biometry charts, obtained from midtrimester, Korean women can be used as a reference value.

To our best knowledge, compounds 1, 2, 12, 13, 17 - 19 and 21-23 were new within Saxifragaceae family. Compounds 15, 16, and 20 were produced from this genus for the first time. Compounds 4, 14 and 25 were first obtained from species P. viburnoides and compounds 3, 5 - 11, and 24 were achieved from the leaves of P. viburnoides for the first time. Furthermore, the anti-neuroinflammatory activity of these isolates was evaluated.

Despite a low risk of liver failure and preserved liver function, non-cirrhotic hepatocellular carcinoma (HCC) has a poor prognosis. In the current study, we evaluated an active regulator of SIRT1 (AROS) as a prognostic biomarker in non-cirrhotic HCC. mRNA levels of AROS were measured in tumor and non-tumor tissues obtained from 283 non-cirrhotic HCC patients. AROS expression was exclusively up-regulated in recurrent tissues from the non-cirrhotic HCC patients (P=0.015) and also in tumor tissues irrespective of tumor stage (P<0.001) or BCLC stage (P<0.001). High mRNA levels of AROS were statistically significantly associated with tumor stage (P<0.001), BCLC stage (P=0.007), alpha fetoprotein (AFP) level (P=0.013), microvascular invasion (P=0.001), tumor size (P=0.036), and portal vein invasion (P=0.005). Kaplan-Meir curve analysis demonstrated that HCC patients with higher AROS levels had shorter disease-free survival (DFS) in both the short-term (P<0.001) and long-term (P=0.005) compared to those with low AROS. Cox regression analysis demonstrated that AROS is a significant predictor for DFS along with large tumor size, tumor multiplicity, vascular invasion, and poor tumor differentiation, which are the known prognostic factors. In conclusion, AROS is a significant biomarker for tumor aggressiveness in non-cirrhotic hepatocellular carcinoma.
