The elevation of total plasmahomocysteine is now an established risk factor for cardiovascular disease. Plasma folate and vitamin {TEX}$B_{12}${/TEX} influence Hcy metabolism as cofactors. In this study, we studied the relationship of major risk factors for cardovascular disease, including advanced age, male gender, obesity, hypertension, hyperglycemia, and dislipidemia and plasma homocyteine, folate and vitamin {TEX}$B_{12}${/TEX} levels in Koreans. A total of 195 adult Koreans participated. The subjects were divided into three groups according to how many major conventional risk factors of cardiovascular disease they had: no risk, low risk (1~3 risk factors) and high risk (>3 risk factors) groups. As the number of risk factors increased, the plasma homocysteine levels significantly increase, while the plasma folate levels significantly decreased. The plasma homocysteine levels re higher in males than in females. The subjects with hyperglycemia had higher plasma homocysteine levels than the subjects without the risk factor. Also the subjects with dislipidemia had higher plasma homocysteine levels than the subjects without the risk factor. The plasma folate and vitamin {TEX}$B_{12}${/TEX} levels were significantly lower in males tan females. However, there were no significant differences in plasma folate and vitamin {TEX}$B_{12}${/TEX} levels between the subjects with or without other risk factors. These results indicate that plasma homocysteine levels were positively related with risk factors for cardiovascular disease and plasma folate levels were negatively related with the risk factors for cardiovascular disease. Also, we conclude that plasmahomocysteine levels might be related to the combination of risk factors, rather than an individual risk factor.

Allergic diseases such as asthma, allergic rhinitis, and atopic dermatitis are heterogeneous diseases characterized by multiple symptoms and phenotypes. Recent advancements in genetic study enabled us to identify disease associated genetic factors. Numerous genome-wide association studies (GWAS) have revealed multiple associated loci for allergic diseases. However, the majority of previous studies have been conducted in populations of European ancestry. Moreover, the associations of single nucleotide polymorphisms (SNPs) with allergic diseases have not been studied amongst the large-scale general Korean population. Herein, we performed the replication study to validate the previous variants, known to be associated with allergic diseases, in the Korean population. In this study, we categorized three allergic related phenotypes, one allergy and two asthma related phenotypes, based on self-reports of physician diagnosis and their symptoms from 8,842 samples. As a result, we found nominally significant associations of 6 SNPs with at least one allergic related phenotype in the Korean population.

Alzheimer's disease is the most common degenerative brain diseases that causes dementia. ${\beta}$-amyloid neuritic plaque density that accumulates in the brain is difficult to perform daily living, such as memory loss, language ability deterioration. It is used to estimate ${\beta}$-amyloid neuritic plaque density in adult patients with cognitive impairment who are being evaluated for Alzheimer's disease and other causes of cognitive impairment. Using the $^{18}F$-Florbetaben with high sensitivity and specificity for the ${\beta}$-amyloid neuritic plaque density to evaluate the usefulness for the early diagnosis of Alzheimer's disease. In $^{18}F$-FDG Brain imaging shows no specific findings. And it appeared on the MR-Brain imaging without atrophy of the hippocampus. However, the intake of ${\beta}$-amyloid neuritic plaque density in $^{18}F$-Florbetaben informs that it is the progress of Alzheimer's disease. Therefore, $^{18}F$-Florobetaben is very useful for early diagnosis of Alzheimer's disease.

Objectives: The purpose of this study was to confirm the relationship between socioeconomic characteristics and the prevalence of periodontal disease, with a focus on employment status, in a representative sample of Korean adults aged 19-39 years. Methods: Data were obtained from 3,178 adults who completed the Korean National Health and Nutrition Examination Survey, health-related questionnaires, and an oral examination. Socioeconomic, demographic, and oral health-related behavior data were adopted as independent variables. The chi-square test was used to assess differences in the distribution of socioeconomic status, oral health behavior, and nutrition factors according to employment status. Logistic regression analysis was performed to confirm the relationships between the prevalence of periodontitis and the related variables. Results: Significant differences in sex, educational level, income, marital status, smoking status, prevalence of periodontitis, number of dental check-ups in a year, and unmet dental care were confirmed according to employment status. The prevalence of periodontal disease was not significantly related to employment status. Conclusions: These results suggest a significant difference in periodontal disease according to socioeconomic factors in Korean adults. However, the prevalence of periodontal disease was not related to employment status. To prevent the progression of periodontal disease, attention should be paid to oral health, time available for dental treatment, smoking cessation, and use of floss.

Periodontal disease is observed in many adult persons. However we has not clear know the molecular mechanism and how to treat the disease at the molecular levels. Here, we investigated the molecular differences between periodontal disease and normal controls using gene expression data. In particular, we checked whether the periodontal disease and normal tissues would be classified by machine learning algorithms using gene expression data. Moreover, we revealed the differentially expression genes and their function. As a result, we revealed that the periodontal disease and normal control samples were clearly clustered. In addition, by applying several classification algorithms, such as decision trees, random forests, support vector machines, the two samples were classified well with high accuracy, sensitivity and specificity, even though the dataset was imbalanced. Finally, we found that the genes which were related to inflammation and immune response, were usually have distinct patterns between the two classes.

Obesity is a serious medical disorder because it can cause a myriad of health problems, such as heart disease, hypertension, and adult-onset diabetes. While conventional medical treatment for obesity has limitations, there is enormous public enthusiasm for complementary and alternative treatments of obesity. This article reviews currently commonly used complementary and alternative therapies for obesity, such as medicinal herbs, nutritional supplements and acupuncture. Beneficial effects and possible adverse effects associated with these treatment are discussed.

Hereditary multiple exostosis is familial disturbance in the growth of cartilagenous bone tissue, most marked at the metaphyseal region of long bone. In most of the reported cases, the disease appears to have been transmitted through the male. And chondrosarcomatous transformation of the exostotic area is not uncommon, particularly in adult subjects.

Witches' broom symptoms were firstly found on tubers of Solanum tuberosum cv, Deijima, showing dense growth of spindly sprouts in Cheju province, Korea. Plantlets from the diseased plants also produced the typical witches' broom symptoms, having densely-growing small leaves when they became adult plants. At the later stages the diseased leaves were blightened. Presence of phytoplasma in plant tissues was confirmed by DAPI-staining fluorescence microscopy and electron microscopy, exhibiting its localization in sieve tubes of stem, petiole, and midrib. This is the first report of potato witches' broom in Korea.
