The aim of this study was to analyze factors related to xerostomia in adults aged 30 years and over. The data were analyzed using the t-test, one-way ANOVA and multiple linear regression analysis in the SPSS version 12.0 program. The results were as follow. 1. The respondents who were older than 51 years old, unemployed and had less than 3 million won of average monthly income were more aware of xerostomia (p<0.05). 2. The respondents who answered poor and moderate for their general and oral health and the group with duplicate medication and comorbidity were more aware of xerostomia (p<0.05). 3. The respondents that had problems in chewing, communication, ordinary activities and complained of pain? discomfort and suffered from anxiety depression were more aware of xerostomia (p<0.001). 4. The respondents that answered frequent dryness on their skin, eyes, lips, and nasal mucosa were more aware of xerostomia (p<0.001). 5. Xerostomia showed highest correlation with quality of life (b=0.436) followed by the number of medications (b=0.239), sense of entire body dryness (b=0.200), feeling of hopelessness (b=0.160) and number of oral mucosa disease symptoms (b=0.099) (p<0.05). According to the results of the study, xerostomia may cause deterioration in quality of life. Thus, it is advised to improve the patient management system among dental professions to prevent various complications caused by xerostomia and conduct regular health education on the cause and management method of xerostomia.

본 연구에서는 LC-MS/MS를 이용한 블루베리의 methanol과 ethyl acetate 추출 분획에 존재하는 대사체의 분석을 통해 효율적인 대사체 profiling의 가능성을 탐색하였다. LC-MS/MS에서 검출되는 대사체를 통계 처리한 결과, methanol 추출 분획에서는 5-O-feruloylquinic acid, malvidin hexoside, malvidin-3-arabinoside, petunidin-3-arabinoside, delphinidin hexoside, delphinidin, petunidin hexoside와 같은 안토시아닌 계열의 화합물들이 존재하였고, ethyl acetate 분획에서는 chlorogenic acid, chlorogenic acid dimer, 6,8-di-C-arabinopyranosylluteolin, luteolin과 같은 플라보노이드 계열의 화합물이 검출되었다. 본 연구는 기존 연구와 달리 대사체학 기법을 이용한 블루베리 추출물 전체 대사물질의 profiling을 시도한 최초의 연구로서 블루베리에 함유된 유용 성분의 스크리닝등 향후 응용 연구에 유용한 기반으로 이용될 수 있을 것으로 기대된다. Metabolite profiling of blueberry (cultivar "Spartan") was performed by extraction using different solvents, methanol and ethyl acetate, through metabolomic analysis using LC-MS/MS. Unsupervised classification method (PCA) and supervised prediction model (OPLS-DA) provided good categorization of metabolites according to the extraction solvents. Metabolites of the anthocyanin family, including delphinidin hexoside, delphinidin, 5-O-feruloylquinic acid, malvidin hexoside, malvidin-3-arabinoside, petunidin-3-arabinoside, and petunidin hexoside, were mainly detected in methanol fractions, whereas those of the flavonoid family, including chlorogenic acid, chlorogenic acid dimer, 6,8-di-C-arabinopyranosyl-luteolin, and luteolin were successfully prepared in the ethyl acetate fraction. Thus, metabolomic analysis of blueberry extracts allows for the simple profiling of whole and distinctive metabolites for future applications.
