Objectives The purpose of this study was to find out whether there were differences of urticaria's disease aspect between patients classified into Sasang Constitution Types(SCTs) and whether those differences could be associated with Ordinary symptoms. Methods Medical records and questionnaires about 117 patients who visited one Korean medicine hospital due to urticaria were collated and statistically analyzed. Results 1) Ages 20 to 30, women, Soeumin(SE) and patients in conditions of chronic urticaria over 6 weeks were the majority among 117 patients in this study. Food and stress were most chosen as the main cause of urticaria. 2) Soyangin(SY) showed more severe symptoms of urticaria than other SCTs. In particular, the severity of pruritus, distribution of lesions and vulnerability to stress was statistically significant compared to other SCTs(p<0.05). SE expressed urticaria's symptoms at the medium-level of SY's and Taeeumin(TE)'s. TE exhibited relatively weak symptoms but TE only had slightly higher number of patients with angioedema compared to other SCTs. Taeyangin(TY) was only one case so more researches are needed. 3) In dispositional symptoms, SY had low quality of sleep and defecation. SE could not digest oily food well, felt dizzy and cold well, and had cold hands and feet. TE could eat and sweat much and tended to snore well. Conclusions In this study, urticaria had common cause of both stress and food in all SCTs but onset and severity of symptoms were different between SCTs. It could interpreted that these differences between SCTs were associated with ordinary symptoms native to each SCT.

Pesticides are useful to eliminate harmful insects and grow crops however, misuse and abuse of pesticides may cause a death of wild birds, livestock, and companion animals. We analyzed residual pesticides in the ingesta and tissues from the dead wild birds, livestock, and companion animals which were suspected pesticide poisoning based on the diagnosis of the Animal Disease Diagnostic Center of National Veterinary Research and Quarantine Service (NVRQS). The samples were primarily brought to NVRQS from local communities and veterinary diagnostic laboratories. The 231 suspicious samples of pesticide poisoning based on the necropsy were analyzed by GC/NPD, GC/FPD, GC/ECD, or GC/MSD in 2008 and 2009. Pesticides were identified from the 55 samples of total 143 samples analyzed in 2008 and from the 34 samples of total 88 samples analyzed in 2009. The pesticide identification rates in 2008 were higher than the rates in 2009. It may have relevance to the increased samples with the outbreak of avian influenza in 2008 in Korea. The concentrations of pesticides found in the dead animals varied and exceeded the respective $LD_{50}$ of pesticides in many cases. Monochrotophos, phosphamidon, and methomyl were the most common pesticides found and those pesticides are high rank sales in Korea. The cause of pesticide poisoning in animal is assuming a misuse and an abuse of commonly used pesticides in Korea.

Hepatocellular cancer is a very common cause of cancer related deaths worldwide. Only 30-40% of patients present with early-stage disease open to curative treatments, such as resection or transplantation, while others can only undergo local therapies or palliative care. Various trans-arterial approaches have been used for treatment of hepatocellular carcinoma in patients who need a down-staging to liver transplantation, and who are not candidates for transplantation or radiofrequency ablation. Transarterial chemoembolization (TACE), transarterial embolization (TAE), drug-eluting beads, and radioembolization have been used for locoregional control, and have been shown to prolong the overall survival when compared with supportive care. In this review, we discuss patient selection, pre- and post-procedure imaging, techniques, safety, and clinical outcomes related to these therapies. Newer advances with future directions in various fields related to trans-arterial therapies are also discussed.

Today, obesity is not recognized as a disease itself but is known to be the indirect cause of much chronic illness. Obesity has an impact on psychological disorders including severe inferiority, damage of body self-image, low self-esteem, personality disorders. The results in an increase of the mortality rate. Therefore, this study attempts to discover and evaluate stressful experience in obese teenagers. For this study, 21 girl students and 19 boy students in Pusan middle or high school located were selected. The data were collected from March to May at 1999. A tape-recorder was used under the permission of the subjects to prevent the loss of spoken information and communication. This study consisted of 563 reponses from girls and 461 responses from boys which were then classified with descriptive expressions and priority classifications. The results generated 72 common elements in girls and 54 common elements in boys. From these elements 24 syntheses of hypothetical definitions and 8 identifications of the structural definitions in both girls and boys were developed. The structural and hypothetical definitions were as follows: The analysis of the data was made through a phenomenological analytic method suggested by Van kamm, which is as follows: 1. Maladjustment to school life; lack of understanding of the teacher, insufficient exercise ability, and a feeling of burden in attending the school obesity program. 2. Conflict in family relationships; lack of understanding from the family, a feeling of alienation. 3. Conflict in friend relationships; lack of understanding among friends, constant comparisons in appearance and body with friends (in girls) and estrangement from friends (in boys). 4. Conflict in acquaintance of the opposite sex; hoping to meet the opposite sex, lack of understanding of boy friends (in girls), feelings of pain, feelings of anxiety (in girls) feelings of burden (in girls) feelings of envy (in boys). 5. Negative body image: shape of body; feelings of pain; feelings of powerlessness; feelings of discomfort, and reception; emotional disorders (in boys), and change of personality (in boys). 6. Health disorder: Physical and psychological discomfort. 7. Feelings of burden in weight control; negative experiences in weight control, interference with family and friends, the difficulty in diet therapy, feelings of burden in exercise (in girls), to be teased by the public through mass media (in boys).

Trichloroethylene(TCE) is widely used as a degreasing solvent in workplaces. TCE is primarily toxic to the nervous system, however, systemic disorder like Stevens-Johnson syndrome has been recently reported in small-scale factories, where the government has had limited information of chemical use. A survey was performed to investigate the actual condition of using TCE and to provide practical information to occupational health service agencies and professionals. This survey was carried out on 103 factories out of 430 factories which were conducted periodic work environment measurement for TCE. Degreasing was the most popular reason for using TCE in Korea, which reached to 94%. TCE was also used as a solvent for rubber in the coating or molding process, and adhesives in the bonding process. Metal fabrication was the most common as 23%, followed by assembling automobile parts (17%), and machinery (12%). Workers exposed to TCE during full-shift were 52% while 48% were exposed during short period of the shift or intermittently. Manual or semi-automatic work occupied 87% while automatic work was just 13%. Though automatic work by a closed system was generally lower exposed to TCE, compared to manual work, it can cause a high exposure when the maintenance system is improper. Semi-automatic work especially like open-top degreasing process can cause a high exposure when local exhaust system with condensing and refrigerating coils in the degreaser does not work well. In conclusion, the survey showed nationwide status of TCE exposure in various aspects. It can be used to monitor workplaces and workers exposed to TCE to prevent occupational diseases.

Diffuse alveolar hemorrhage is a rare but serious and frequently life-threatening complication of a variety of conditions. The first goal in the management of patients with diffuse alveolar hemorrhage is to achieve or preserve stability of the respiratory status. Subsequently, the differential diagnosis is aimed at the identification of a remediable cause of the alveolar hemorrhage. The most common causes of diffuse alveolar hemorrhage with glomerulonephritis are microscopic polyangiitis and Wegener's granulomatosis, followed by Goodpasture syndrome and systemic lupus erythematosus. Microscopic polyangiitis (MPA) is a distinct systemic small vessle vasculitis affecting small sized vessels with few or no immune deposits and with no granulomatosus inflammation. The disease may involve multiple organs such as kidney, lung, skin, joint, muscle, gastrointestinal tract, eye, and nervous system. MPA is strongly associated with antineutrophil cytoplasmic autoantibody (ANCA) that is a useful serological diagnostic marker for the most common form of necrotizing vasculitis. Our report concerns a case of microscopic polyangiitis with diffuse alveolar hemorrhage in a 54-year-old man. He was admitted to our hospital due to dyspnea upon exertion and recurrent hemoptysis. Laboratory findings showed hematuria, proteinuria and deterioration of renal function. In the chest CT scan, diffuse ground glass appearance was seen in both lower lungs. A lung biopsy revealed small vessel vasculitis with intraalveolar hemorrhage and showed a positive reaction to against perinuclear ANCA. The patient was treated with prednisolone and cyclophosphamide. Chest infiltration decreased and hemoptysis and hypoxia improved. He is still being followed up in our hospital with a low dose of prednisolone.

Pulmonary fibrosis is a common consequence of many lung diseases and a leading cause of morbidity and mortality. The molecular mechanisms underlying the development of pulmonary fibrosis remain poorly understood. One model used successfully to study pulmonary fibrosis over the past few decades is the bleomycin-induced pulmonary fibrosis model. We aimed to identify the genes associated with fibrogenesis using an Affymetrix GeneChip system in a bleomycin-induced rat model for pulmonary fibrosis. To confirm fibrosis development, several analyses were performed, including cellular evaluations using bronchoalveolar lavage fluid, measurement of lactate dehydrogenase activity, and histopathological examinations. Common aspects of pulmonary fibrosis such as prolonged inflammation, immune cell infiltration, emergence of fibroblasts, and deposition of extracellular matrix and connective tissue elements were observed. Global gene expression analysis revealed significantly altered expression of genes ($\geq$ 1.5-fold, p < 0.05.) in a time-dependent manner during the development of pulmonary fibrosis. Our results are consistent with previous results of well-documented gene expression. Interestingly, the expression of triggering receptor expressed on myeloid cells 2 (Trem2), secreted phosphoprotein 1 (Spp1), and several proteases such as Tpsab1, Mcpt1, and Cma1 was considerably induced in the lung after bleomycin treatment, despite little evidence that they are involved in pulmonary fibrogenesis. These data will aid in our understanding of fibrogenic mechanisms and contribute to the identification of candidate biomarkers of fibrotic disease development.

Background: Colorectal cancer is the third most common cancer in both men and women in the world and the second leading cause of cancer-related deaths. The incidence of colorectal cancer has increased in Iran in the past three decades and is now considered as a serious problem for our society. This cancer has two types hereditary and non-hereditary, 80% of cases being the latter. Considering that the relationship between SNPs with diseases is a concern, many researchers believed that they offer valuable markers for identifying genes responsible for susceptibility to common diseases. In some cases, they are direct causes of human disease. One SNP can increase risk of cancer, but when considering the rate of overlap and frequency of DNA repair pathways, it might be expected that SNP alone cannot affect the final result of cancer, although several SNPs together can exert a significant influence. Therefore identification of these SNPs is very important. The most important loci which include mutations are: MLH1, MSH2, PMS2, APC, MUTYH, SMAD7, STK11, $XRCC_3$, $DNMT_1$, MTHFR, Exo1, $XRCC_1$ and VDR. Presence of SNPs in these genes decreases or increases risk of colorectal cancer. Materials and Methods: In this article we reviewed the Genes and SNPs associated with non-hereditary and hereditary of colorectal cancer that recently were reported from candidate gene y, meta-analysis and GWAS studies. Results: As with other cancers, colorectal cancer is associated with SNPs in gene loci. Generally, by exploring SNPs, it is feasible to predict the risk of developing colorectal cancer and thus establishing proper preventive measures. Conclusions: SNPs of genes associated with colorectal cancer can be used as a marker SNP panel as a potential tool for improving cancer diagnosis and treatment planning.

Objective : Despite rapid evolution of shunt devices, the complication rates remain high. The most common causes are turning from obstruction, infection, and overdrainage into mainly underdrainage. We investigated the incidence of complications in a consecutive series of hydrocephalic patients. Methods : From January 2002 to December 2009, 111 patients underwent ventriculoperitoneal (VP) shunting at our hospital. We documented shunt failures and complications according to valve type, primary disease, and number of revisions. Results : Overall shunt survival time was 268 weeks. Mean survival time of gravity-assisted valve (GAV) was 222 weeks versus 286 weeks for other shunts. Survival time of programmable valves (264 weeks) was longer than that of pressure-controlled valves (186 weeks). The most common cause for shunt revision was underdrainage (13 valves). The revision rate due to underdrainage in patients with GAV (7 of 10 patients) was higher than that for other valve types. Of 7 patients requiring revision for GAV underdrainage, 6 patients were bedridden. The overall infection rate was 3.6%, which was lower than reported series. Seven patients demonstrating overdrainage had cranial defects when operations were performed (41%), and overdrainage was improved in 5 patients after cranioplasty. Conclusion : Although none of the differences was statistically significant, some of the observations were especially notable. If a candidate for VP shunting is bedridden, GAV may not be indicated because it could lead to underdrainage. Careful procedure and perioperative management can reduce infection rate. Cranioplasty performed prior to VP shunting may be beneficial.

This presentation firstly is discussed the characteristics of estrus, the time of first postpartum estrus, and the relative accurate of various estrus detection aids and secondly discussed the abnormalities of estrus and ovarian function and its control by treatment of exogenous hormones in cattle and pig. Longer estrus cycles as well as the shorter than 18 day cycles showed the lowered conception rates as compared to the normal cycles of 18 to 25 days. Other characteristics of est겨s such as duration of estrus, intensity of estrus and time of estrus are reviewed to affect fertility. The first postpartum ovulation and estrus in cows usually occurs about 20 to 30 days and 40 to 50 days after parturition, respectively. Irregularities in estrus cycle length have been conducted during early postpartum period. In sows, weaning is followed by ovulation and estrus although there is some individual variation. The most common method of estrus detection is direct visual observation on standing estrus behavior, but various aids of estrus detection have been empolyed with varying degree of effectiveness. The results from heat detector devices are about as accurate as twice-daily observation(about 90%). The abnormal estrus can be classified into three types; irregular or continuous estrus, silent estrus and anestrus. Cystic ovarian disease, follicular cysts and luteal cysts, is a serious cause of reproductive failure in cattle and pig. The follicular cysts are much more common than luteal cysts and the incidence of ovarian cysts in dairy cattle is higher than beef cattle and pig. The occurrences of ovarian cysts have been closely associated with levels of milk production, stages of postpartum period, nutritional levels and seasons. The luteal cysts and persistent corpora lutea are responsive to the luteolytic effects of the recently synthetic analogues of PGF2$\alpha$ in cows and sows and recently GnRH or LH-RH has been successfully used as a treatment for cows and sows with ovarian follicular cysts.
