Present studies were carried out to produce tetraploid plants by colchicine treatment using seeds, seedlings and shoot tips of Platycodon grandiflorum in Campanulaceae. The most successful colchicine treatment for tetraploid production in P. grandiflorum was soaking treatment using 0.01 and 0.5% colchicine solution for 1 hour and 12 hours, respectively. Morphological characteristics of both diploid and tetraploid were similar, but tetraploid plants had more leaves. Compared to diploid, tetraploid had the larger stomata, but less number of stomata. Fresh weight of tetraploids was 20∼40% heavier than that of diploid.

Spontaneous retroperitoneal hemorrhage due to hemophilia A with impaired coagulopathy is very rare. Spontaneous retroperitoneal hemorrhage has been recorded as having originated from many retroperitoneal organs and blood vessels, and it may be due to local and/or systemic factors. In the majority of the patients, kidney and adrenal gland were the major site of hemorrhage. The systemic causes of spontaneous retroperitoneal hemorrhage are anticoagulation therapy and chronic hemodialysis. During the course of these treatments, hemorrhagic complications may occur at many site, including the retroperitoneal space. Blood dyscrasias including leukemia, polycythemia, sickle cell trait and hemophilia have been reported associated with spontaneous retroperitoneal hemorrhage. We report a case of spontaneous retroperitoneal hemorrhage occurred in a gemophilia A patient with brief review of literature
Breeding of Tetraploid in Codonopsis lanceolata (Sieb. et Zucc.) Trautvetter by Colchicine Treatment

Present studies were carried out to produce tetraploid plants by colchicine treatment using seeds, seedlings and shoot tips of Codonopsis lanceolata. Three tetraploid plants of C. lanceolata were produced from seeds which absorbed 0.1 % colchicine solution for 12 hours, and 0.5% colchicine solution for 1 and 6 hours from seedlings, respectively. But tetraploid was not produced from shoot tips treated by colchicine solution. Compared to diploid, tetraploid plants had larger stomata, but less number of stomata. Fresh weight of tetraploid plants was 1.4∼3.6 times heavier than diploid plants.

Background: Urinary kidney injury molecule-1 (KIM-1) is an early and sensitivebiomarker of acute kidney injury, but it is unclear if it is a biomarker of chronicglomerulonephritis. We evaluated whether urinary KIM-1 levels in patients withimmunoglobulin A (IgA) nephropathy can be a marker to reflect clinicopathologicalseverity and predict the prognosis. Methods: We measured urinary KIM-1 levels in 40 patients (15 males; mean age36.6712.9 years) with IgA nephropathy and 10 healthy people (5 males; mean age37.379.6 years) as controls. The correlation of urinary KIM-1 levels with patients’clinical parameters, histological grades, and follow-up data were analyzed using themodified H. S. Lee grading system and tubulointerstitial change scores. Results: Urinary KIM-1 levels were higher in patients with IgA nephropathy thanhealthy controls (P¼0.001). Univariate and multivariate regression analyses showedthat urinary KIM-1 levels had a direct correlation with H. S. Lee grade andtubulointerstitial inflammation (P¼0.004 and P¼0.011, respectively). Conclusion: In patients with IgA nephropathy, urinary KIM-1 has a significantcorrelation with histopathologic severity.

With the widespread use of fertility medications and techniques of in vitro fertilization, multiple gestation has become epidemic in modern obstetric practice. Delivery of the initial fetus in a multiple gestation usually is followed by delivery of the subsequent fetus or fetuses shortly thereafter. However in rare circumstances, the delivery is delayed for days due to disappearance of uterine contraction after delivery of the first fetus. When uterine activity ceases after the delivery of the first neonate, a policy of nonintervention may be considered in case of an immature or very premature delivery, in order to achieve a gestational age for the remaining fetus(es) more compatible with neonatal survival. We report a case of twin gestation with prolongation of the delivery interval between the twins for 46 days.

In this paper composites-aluminum hybrid structure for 3-axis micro-CNC machining center was introduced to enhance the structural stiffness and damping capacity of the structure. Three types of composites-aluminum hybrid column were proposed; that is, composite reinforcement at 2 lateral surfaces and 4 lateral surfaces and partly reinforced structure (composite jacket) for damping enhancement. Finite element analyses for static deflection due to dead weight and natural frequency were carried out according to the stacking angle and thickness and the most appropriate condition for the design of the composites-aluminum hybrid structure was determined.

Since 1996, many Korean companies such as Samsung, LG, Hyundai Motor Company, have adopted Six Sigma in order to get a competitive edge in the global marketplace. There are, however, many problems to be solved for successfully implementing Six Sigma in an organization. As is known, one of the key principles of Six Sigma is a data-based management or a decision making based on data. Therefore, Six Sigma requires more measurement than ever, which makes measurement system analysis more important. Usually, a gage R&R study is performed to identify the measurement system's variation relative to process variation. In the study, a gage R&R study is considered for the case where measuring a major quality characteristic accompanies a destructive testing. We suggest a gage R&R study using a screening variable that is highly correlated with the major quality characteristic and also can be measured by a nondestructive testing method. It is assumed that the major quality characteristic and a screening variable have a bivariate normal distribution. A simulation study on the proposed method is performed and we compare it with the conventional gage R&R study for a destructive testing.

We have examined the relaxational reponse to the water extract of Angelica gigas Nakai (AG), A. sinensis(Oliv.) Diels (AS), A. acutiloba Kitagawa (AA), and Four-Substance Decoctions (AG-FSD, AS-FSD, AA-FSD) in isolated thoracic aorta from sprague dawley(SD) rat in the presence and absence of endothelium. Rat thoracic aorta was investigated in vessel segments suspended for isometric tension recording by polygraph. Responses to AG, AS, AA and AG-FSD, AS-FSD, AA-FSD were investigated in vessels precontracted with 5-hydroxytryptamine(5-HT) were compared in vasodilation effect. We found that the thoracic aorta segments responded to AG, AS, AA and AG-FSD, AS-FSD, AA-FSD with a dose-dependent vasodilation. The 5-hydroxytryptamine induced contraction at 10-4M were inhibited by 26.3%, 2.7%, 2.1% and 24.6%, 1.1%, 3.2% after addition of the 0.1 g/㎖ water extract of AG, AS, AA and AG-FSD, AS-FSD, AA-FSD. The 5-hydroxytrptamine induced contraction at 10^-4M with and without endothelium were inhibited by 24.6% and 6.9% after addition of the 0.1 g/㎖ water extract of AG-FSD. In conclusion, AG, AS, AA and AG-FSD, AS-FSD, AA-FSD-induced relaxation in the isolated rat thoracic aorta were composed of dose-dependent relaxation. AG-FSD has very potent vasodilation.
