For the investigation of occurrence of insect pests and their natural enemies, total number of 353 controlled agricultural farms were visited and surveyed. In the 73% of total controlled agricultural farms, 52 species insect pests were occurred. Among these pests, the western flower thrip (Frankliniella occidentalis), the two spotted spider mite (Tetranychus urticae), the greenhouse whitefly (Trialeurodes vaporariorum), the cotton aphid (Aphis gossypii) and the green peach aphid (Myzus persicae) were mainly occurred. On the other hand, small numbers of natural enemies were sustained in 40 controlled agricultural farms, which was 11% and 17% of visited farms and pest occurred farms, respectively. For the most part of collected natural enemies, there were included in Braconid, Coccinellid and Anthocorid, as 63, 20 and 8% of them, respectively.

Purpose : To compare cephalometric measurement between measuring methods in digital and conventional lateral cephalometric radiograph. Materials and Methods : Twenty digital and conventional lateral cephalometric radiographs were selected. In digital group, cephalometric measurements were performed manually using hardcopies and automatically using VCeph^(TM) program on the monitor. In conventional group, the same measurements were performed manually on conventional films, and for automatic measurement conventional films were digitized by scanner. All measurements were performed twice by 4 observers, and 24 cephalometric variables were calculated and the time spent for each measurement was recorded. The differences in measurements data and the time spent for each measurement were compared within each group. Intra-observer and inter-observer comparisons were performed. Results : In both groups, no statistically significant difference between manual and automatic measurements was observed and most of the variables didn’t show statistically significant differences between methods. The observer with less experience tended to show statistically significant differences of measurements between methods, and differences from other observers. The differences of measurements between methods in digital group were lesser than those of conventional group with statistical significance in 8 variables out of 24. With automatic method and in digital group, the spent time was shorter. Conclusion : With direct digital radiograph, automatic method using manually idenitified landmarks can be preferable in cephalometric analysis.

A clinical observation was done on 38 children with idiopathic nephrotic syndrome, who had been admitted to our pediatric department during 2 years and 9 months period, from January 1978 to September 1980. The following results were obtained: At the beginning of illness. 42% were in the age group of 3-7 year, and male to female ratio was approximately 3:1 of male preponderance. During initial attack and subsequnt relapses, pitting edema on extremities was noticed in all cases, followed in frequency by generalized edema in 71%, ascites and/or pleural effusion in 65.8% and GI trouble in 47.4%. Response to initial continuous steroid therapy showed complete remission(group 4) in 37.8%, partial remission (group 2&3) in 46% and no response (group 1) in 16.2%. Within 2 weeks after institution of steroid therapy, both diuresis and disappearance of proteinuria were noted in 57.1%. Nephritic manifestations, eg. hematuria, hypertension & azotemia, were seen in 21.6%, 10.8%, 24.3% respectively, and the majority of children with these manifestation showed poor response to steroid therapy. Nine out of 21 patients in whom follow-up could be done over 1 year, experienced one or more relapses, giving 43% relapse rate during the 1st year, and URI was accompanied in about half of these episodes. Percutaneous renal biopsy done on 17 patients who showed steroid dependency, or no response to poor response toward steroid therapy showed the following results: Minimal change nephrotic syndrome in 8, membranous nephropathy in 3, membranoproliferative glomerulonephritis in 3, focal segmental sclerosis in 1 and focal proliferative glomerulonephritis in 2. And male to female ratio was 13:4. "Pulse therapy" with bolus dosage of methylprednisolone was tried on 9 patients, resulting in disappearance of relapse, or significant improvement in blood chemistry & urinary finding in 5. And 2 out of 5 patients in whom immunosuppressant therapy with cytoxan was given due to poor response to steroid, experienced complete remission. During the same study period, secondary nephrotic syndrome was observed in 6 out of 54 patients with acute glomerulonephritis, and heavy proteinuria alone, defined as proteinuria over 2gm/㎡ day, was seen in 6 patients with acute glomerulonephrits and 2 patients with congestive heairt failure.

Purpose: Purposes of this study were to understand the current trends on complementary therapy in relieving chemotherapy-induced nausea and vomiting and to suggest the future research direction. Method: Subjects were selected on CINAHL, MEDLINE, Korean Academy Data Base from 1980 to 2001 which used nausea, vomiting, chemotherapy and complementary therapy as key words in experimental studies. Eight korean articles and twenty-one international articles were analyzed in terms of general characteristics, research methods, and types of complementary therapy. Data were analyzed by using descriptive statistical methods. Result: Since 2000, researchers have more actively used complementary therapy. In subject characteristics, mean age was 35.5 years old, 45% of the researchers were performed with high level of incidence of chemotherapy induced vomiting, 14% of them set limit of consecutive cycle during research, and 65% of them did not comment the selecting criteria of sample. About 60% of them were designed post-test only control group: 35% used INV by Rhodes, 31% used Likert scale, and 24% used VAS for dependent variable. Muscle relaxation therapy was mostly applied for relief of nausea and vomiting. Conclusion: Further studies will be needed to control extrinsic variables affecting nausea and vomiting in research design and to accumulate evidence with studies applying various complementary therapies.

In this study, we isolated scopoletin from <em>Cirsium setidens</em> Nakai (Compositae) and tested its effects on melanogenesis. Scopoletin was not toxic to cells at concentrations less than 50 μM and increased melanin synthesis in a dose-dependent manner. As melanin synthesis increased, scopoletin stimulated the total tyrosinase activity, the rate-limiting enzyme of melanogenesis. In a cell-free system, however, scopoletin did not increase tyrosinase activity, indicating that scopoletin is not a direct activator of tyrosinase. Furthermore, Western blot analysis showed that scopoletin stimulated the production of microphthalmia-associated transcription factor (MITF) and tyrosinase expression via cAMP response element-binding protein (CREB) phosphorylation in a dose-dependent manner. Based on these results, preclinical and clinical studies are needed to assess the use of scopoletin for the treatment of vitiligo.

In this study, we isolated scopoletin from Cirsium setidens Nakai (Compositae) and tested its effects on melanogenesis. Scopoletin was not toxic to cells at concentrations less than $50{\mu}M$ and increased melanin synthesis in a dose-dependent manner. As melanin synthesis increased, scopoletin stimulated the total tyrosinase activity, the rate-limiting enzyme of melanogenesis. In a cell-free system, however, scopoletin did not increase tyrosinase activity, indicating that scopoletin is not a direct activator of tyrosinase. Furthermore, Western blot analysis showed that scopoletin stimulated the production of microphthalmia-associated transcription factor (MITF) and tyrosinase expression via cAMP response element-binding protein (CREB) phosphorylation in a dose-dependent manner.

Functional and Structural Characterization of Drosocin and its Derivatives Linked O-GalNAc at Thr¹¹ Residue

Ahn, Mi-Ja,Sohn, Ho-Ik,Nan, Yong Hai,Murugan, Ravichandran N.,Cheong, Chae-Joon,Ryu, Eun-Kyoung,Kim, Eun-Hee,Kang, Shin-Won,Kim, Eun-Joo,Shin, Song-Yub,Bang, Jeong-Kyu Korean Chemical Society 2011 Bulletin of the Korean Chemical Society Vol.32 No.9

Antimicrobial peptides have recently gained the much attention because of their ability to make defense system from attacking bacterial infections. Drosocin has been considered as very attractive antibiotic agents because of low toxicity against human erythrocytes and active at the low concentration. We have studied the structureactivity relationship of a glycopeptide drosocin focused on the N-acetyl-D-galactoside at $Thr^{11}$ residue. Based on the radial diffusion assay, we found that the acetylation of carbohydrate moiety increased the antimicrobial activity and the $Pro^{10}$, present in the middle of drosocin plays an important role in the antimicrobial activity. Our results provide a good lead compound for further studies on the design of drosocin-based analogues targeting glyco linked Thr site.
