Background: Familial adenomatous polyposis (FAP) is a disease inherited in an autosomal dominant fashion. Most FAP patients develop upper gastrointestinal polyps; especially those in the antrum and duodenum are usually neoplastic. The aim of this study was to evaluate the prevalence of gastroduodenal polyps in Iranian FAP patients. Materials and Methods: 28 patients affected by FAP underwent front-view and side-view endoscopy. Papillary biopsies were performed in all patients. Location of polyps, their number and size, pathology study, patient general information (gender, age, family history of FAP or colorectal cancer and gastroduodenal polyps) were analyzed. Results: Gastric polyps were seen in 39.3 % of patients. Some 72.7% of the affected individuals had fundic gland polyps and 36.36% had hyperplastic polyps. Duodenal adenoma was observed in 25% of patients. While 57% of patients had tubular adenoma with low grade dysplasia, 42.8% showed tubulovillous adenoma with low grade dysplasia. Conclusions: Findings of this study indicated that the prevalence of gastroduodenal polyps in FAP patients is high and dysplasia may be evident in duodenal polyps. Therefore, it appears that routine gastroduodenal endoscopy in FAP patients is necessary.

Objectives: Dropout and weight regain are common problems in most obesity treatments. The purpose of this study was to review previously published study results of the predictive factors associated with dropout during weight loss treatment and weight loss maintenance after successful weight loss. Methods: Authors searched for the articles related to dropout and weight loss maintenance, published from 2007 to 2016 found on Pubmed, Scopus, RISS, and KISS. A total of 19 articles were finally selected. From the study results, unchangeable and changeable predictors were extracted, and these predictors were examined according to dropout and weight loss maintenance categories. Results: The unchangeable predictors of dropout were younger age, lower education level and female, whereas the changeable predictors of dropout were lower initial weight loss, symptoms of depression and body dissatisfaction. The strongest factor for predicting the dropout was initial weight loss. The unchangeable predictors of weight loss maintenance were old age, male and family history of obesity, whereas the changeable predictors of weight loss maintenance were regular exercise, dietary restraint, self-weighing and low depressive symptoms. Initial weight loss, depressive symptoms, body image, dietary restraint, physical activity, weight loss expectation and social support were considered to be dominant factors for weight loss treatments. Conclusions: Our review results suggest that unchangeable and changeable predictors of dropout and weight loss maintenance should be carefully examined during treatments of obesity.

Naturalized plants were identified and recorded in South Korea based on field surveys and related literatures. These plants consisted of 321 taxa in total, belonging to 40 families, 175 genera, 302 species, 15 varieties and 4 forms. Among the plants the family Compositae was dominant containing 68 taxa (21.2% of the total population) and Poaceae with 62 taxa (19.3%) successively. Most of the plants were herbs and only 7 taxa trees. 221 taxa (68.8%) appeared to have invaded the country during the third period (1964-2010). 41.8% (134 taxa) of the total population were originated from Europe. These invasive plants were assessed with the degree of naturalisation which was categorized as I-V types.

Information on plant diversity and community structure are required to chalk out necessary actions for conservation management. The present study assessed the composition and diversity of tree species in Kamalachari Natural Forest of Chittagong South Forest Division, Bangladesh, during April 2010 to November 2011. A total of 107 tree species belonging to 72 genera and 37 families were recorded, where Moraceae family was represented by maximum (11) species. Density, Basal area and volume of tree species were $418{\pm}20.09stem/ha$, $21.10{\pm}2.62m^2/ha$ and $417.4{\pm}79.8m^3/ha$ respectively. Diameter and height class distribution of tree species revealed an almost reverse J-shaped curve. Both the number of species and percentage of tree individuals were maximum in the lower DBH and height ranges. Anthropogenic disturbances like illegal tree cutting, over extraction, settlement inside forest area etc. were noticed during the study, which are supposed to cause gradual decrease of both tree species and individuals in the higher DBH and height classes. However, Artocarpus chama was found dominant showing maximum IVI followed by Schima wallichii, Aporosa wallichii, and Lithocarpus acuminata. The quantitative structure of the tree species of Kamalachari natural forest is comparable to other tree species rich tropical natural forests. The findings of the study may help in monitoring future plant population changes of the identified species and adopting species specific conservation programs in Kamalachari natural forest.

The modern cartilaginous fishes, class Chondrichthyes, are small group of Pisces, and comprisingmore 1,000 described valid species, and including approximately 190 genera, 55 families, and 15 orders. The Chondrichthyes consists of two subclasses, the Holocephali (chimeras) and the Elasmobranchii(sharks and rays). The dominant subclass Elasmobranchii includes sharks (Selachii) and rays (Batoidea), the former is more diverse than the latter in higher taxa (order, family, genus) but has fewer species. The Batoidea, batoids or rays, has long been recognized as monophyletic, however, the interrelationships of the groups are problematic and uncertain. In order to review biodiversity and systematics of batoids, valid species name and supraspecific taxa from the published materials are studied. Batoids (including sawfishes, Pristiformes; electric rays, Torpediniformes; stingrays, Myliobatiformes; skates, Rajiformes; wedgefishes, Rhiniformes; and guitarfishes, Rhinobatiformes) is speciose and worldwide with about 580 species in 4 to 6 orders, 17 to 19 families, and about 75 genera. In East Asian waters, the previous records of the Batoidea reveal about 170 species belonging to 41 genera, 18 families, 6 orders. The largest group of batoid fauna in the area is order Myliobatiformes comprising about 80 species, 16 genera of 7 families. The predominant families are Dasyatidae (whiptail stingrays: 46 spp. of 6 genera), Arhynchobatidae (softnose skates: 26 spp. of 3 genera), and Rajidae (skates: 21 spp. of 6 genera). The predominant genera are Bathyraja (softnoseskates: 20 spp.), Himantura (whiprays:19spp.), and Dasyatis (fantailstingrays: 18 spp.). There are 23 species in the Yellow Sea, 70 species in the East China Sea, 82 species in the South China Sea, and 58 species in the North Pacific coast of Japan. Batoid fauna from the East Sea (Sea of Japan) is the poorest of the five regions, consisting of 14 species. Korean waters include only 28 species, 16 genera, 10 families and 5 orders of batoids. Two species is torpediniforms, 4 rhinobatiforms, arhynchobatiforms, 11 rajiforms and 10 myliobatiforms. By the earlier works, the systematics and a check list of the valid species of batoids will be presented.

Hereditary pancreatitis (HP) appears as an autosomal dominant trait. If the patient has (1) more than 2 affected relatives in different generations and (2) no known etiological factors such as alcohol or gallstones, or has R122H or N29I mutation in the cationic trypsinogen (CT) gene, the diagnosis of HP can be applied. Risk of pancreatic cancer is estimated to be 53-fold higher than in a general population after the age of 50 years. We report a kindredof HP, involving three of its family together; two siblings (14 years old, 13 years old) and cousin (26 years old). The patient had complicating chronic pancreatitis and pancreatic stone, and was treated with amodified Puestow-Gillesby procedure. Her sisters showed chronic pancreatitis. Her cousin underwent a drainage procedure of the pancreatic duct for chronic pancreatitis during the high school period. All the three members showed the R122H mutation of the CT gene.

Understanding the purpose and results of a Korean Envoy's medical bureaucrat (attendant) travel to China. Unlike other Envoy's medical bureaucrats, envoy's trade made profits for those who participated. This article investigates the protocols of a Korean Envoy's medical attendant which include: (1) A prominent family member or high-ranking official does not participate in the Envoy's medical bureaucrat, either himself or his descendants. This denies the general theory that the medicinal material trade helped the economic status of medical officials. (2) Envoy's medical bureaucrat is a high percentage of interpreter bureaucrat in the households of father, mother, and wife. This suggests that the information about the envoy schedule and the benefit of the envoy may have been exposed in advance. This is related to the fact that the interpreter bureaucrat is the center of the envoy trade. (3) In the nineteenth century, envoy's medical bureaucrats were more frequent among close relatives, such as father-son relationship, than in the previous century. This study restored the lineage and purpose to the medical bureaucrat's travel to China, and provides a list of Envoy's medical bureaucrat through historical data, and analyzed the household and previous office. In this regard, it can be seen that some households, which are not dominant medical bureaucracies, have pursued profit through medicinal material trade. However, it is difficult to generalize to the whole of the medical bureaucracy.

The purpose of these study was to analyze the contents and trend of researches done on oncology nursing in the past five years in Korea and to suggest its direction for the future research. Methods: 214 nursing studies published from 1998 to 2003 were selected for the analysis. They were examined for the source, design of study, type of subjects, the intervention outcomes of experimental research, the key words and theme of the oncology research. Results: 1. 139(64.9%) of 214 studies were masters thesis and doctoral dissertations. There were 196(91.6%) quantitative researches and 18 qualitative researches. Quantitative research consisted of 28(14.3%) experimental and 168(85.7%) non- experimental studies. Among non-experimental studies, there were 53 correlations, 78 descriptives, 14 comparatives and 23 methodological studies. 2.The main subjects of the study were cancer patients in general(43.7%) and breast cancer patients (18.3%). According to the treatment types, patients receiving chemotherapy were the highest number distribution as 23 of all researches. 3. Social support, fatigue, stress, hope, and quality of life were the most frequently used concepts in correlational studies.4. Education, providing information, oral care, exercise, relaxation and foot massage were the most frequent nursing interventions. Most frequently measured outcomes variable were self-care, pain control, nausea & vomiting, oral discomfort and anxiety. 5. Key words used most frequently were quality of life, educational need, pain controls and fatigue. 6. The themes of qualitative researches were illness experience, family experience and adaptation process. More than 50% of qualitative researches used phenomenologic method. Conclusion: Researches on cancer nursing in Korea have been increased. Descriptive design is being dominant and few experimental studies are being done For the future, it is necessary to conduct international studies to compare, replicate and to establish the effective nursing interventions.

Herpesvirus saimiri (HVS), a member of the $\delta$-herpesvirus family, encodes an oncoprotein called Saimiri Transforming Protein (STP) which is required for lymphoma induction in non-human primates. Previous study has shown that STP-C, an oncoprotein of HVS, activates NF-$\kappa$B signaling pathway. However, the detailed mechanism of STP-Cmediated NF-$\kappa$B activation has not been reported yet. We first report that STP-C interacts with TRAF6 protein in vivo and in vitro and further investigation shows that $Glu_{12}$ residue of STP-C is critical for binding to TRAF6. Introduction of ubiquitin together with STP-C augments NF-$\kappa$B activity compared to that of STP-C expression alone. STP-C expression further induces ubiquitination of endogenous TRAF6. In addition, either a deubiquitination enzyme, CYLD or a dominant negative E2-conjugation enzyme reduced NF-$\kappa$B activity in spite of the presence of STP-C, supporting that the interaction between STP-C and TRAF6 induces ubiquitination of TRAF6. NF-$\kappa$B activation by STP-C through the ubiquitinated TRAF6 causes the increased production of IL-8, an inflammatory chemokine and the enhanced expression of costimulatory molecule ICAM, which might ultimately contribute cellular transformation by the exposure of HVS-infected cells with inflammatory microenvironment and chronic activation.

Spinal muscular atrophy (SMA) is the second most common fatal disease of childhood with autosomal dominant mode of inheritance, and in its less severe form the third most common neuromuscular disease of childhood after Duchenne muscular dystrophy. The genetic defect was found to be on the long arm of chromosome 5 (5q11.2-q13.3) where many genes and microsatellite markers were missing. One of the most important genes is the Survival Motor Neuron (SMN) gene which is homozygously missing in 90% of SMA patients. Another important gene, the Neuronal Apoptosis Inhibitory Protein (NAIP) gene was found to be defective in 67% of SMA type I patients. Studies so far suggest SMA occurs when the genes on the long arm of chromosome 5 are mutated or deleted. Recently our hospital encountered 2 SMA patients of type I and II respectively. These patients both had homozygously defective SMN genes but intact NAIP genes. We are reporting these cases with bibliographic review and discussion. Korean SMA patients presumably have defects in SMN genes similar to those found in European patients, although the significance of NAIP genes remains to be established. SMN gene defects can be easily diagnosed using PCR and restriction enzymes, and this method could be applied towards convenient prenatal diagnosis and towards screening for family members at risk.
