This study was performed to investigate the influence of dietary fiber from the whole food on the composition of intestinal microflora in rats. The fiber sources of experimental diets were prepared by drying and milling of small water dropwort(WD), mugwort(MW), butterbur(BB) and apple(AP). Each fiber sources was mixed at the 15% level of the diet. The level of dietary fiber in WD, MW, BB diets was simillar but that in AP diet was slightly low. Male rats of Sprague-Dawley strain were blocked into 5 groups: WD, MW, BB, AP, FF(fiber free), The animal was fed ad libitum each of experimental diets for 37 days. Total viable counts and the numbers of Lactobacillus, Bifidobacterium, Bacteroidaceae, Eubacterium, Peptococcaceae, Streptococcus, Clostridium, Staphylococcus, E. coli were determined by nonselective and various selective media. Food intake of AP and FF groups were lower than the other groups, FF group was lower than the other groups in flood efficiency ratio. Total viable counts were the highest in FF group. The number of Bacteroides, Eubacterium were higher in AP group compared with other groups and that of streptococcus was lower in MW, BB, AP groups than others. The number of Lactobacillus was higher in WD, MW, BB groups than the other groups and that of Bifidobacterium was higher in BB, AP groups. A decrease in the intestinal population of Clostridium was shown in MW, BB groups. These findings suggests that the samll water dorpwort, mugwort butterbur are effective in improving intestinal flora of rats.

The purpose of this study was to evaluate the effects of a sealant resin on enamel demineralization in orthodontic bracket bonding. The forty eight extracted sound bovine teeth was subdivided into four groups and treated with Phase Ⅱ^(r) on the surface. Group 1 was not treated, Group 2 was acid etched with 37% phosphoric acid for 30 seconds, Group 3 was sealant applied after acid etching and Group 4 was resin paste applied after acid etching and sealant application. Each group was demineralized in artificial caries solution. Demineralized enamel depth was measured using by confocal laser scanning microscopy. The results were as follows. 1. The mean demineralized enamel depth was Group 1 (47.4㎛), Group 2 (61.8㎛), Group 3 (13.9㎛), Group 4 (8.2㎛). 2. The demineralized enamel depth was increased in Group 2 than Group 1 (p<0.05). 3. The demineralized enamel depth was reduced in Group 3 than Group1 and Group 2 with statistically significant differences (p<0.05). 4. Group 4 was very little demineralized. The results of the present study indicate that sealant application is useful for reducting enamel demineralization in orthodontic bracket bonding.

Before conducting the health promotion program, we surveyed the health risk appraisal(HRA) of 210 workers (186 men and 24 women) in a computer company, for the need assessment, selection of target population, priority setting, and as a standard for comparision after performing the program. The smokers were 115(88.6%), and drinkers (over 1 bottle of Soju per week) were 91(44.8%) in men. Entire women and 148(78.0%) men never or irregularly exercise. Type A personality were 73(39.2%) in men, 8(33.3%) in women, and 26(14.0%) of men and 6(25.0%) of women were high stress risk group. 53(25.2%) of men and 2(8.3%) of women were obese (BMI ≥25kg/m²), and workers who consumed exess of total calory compared with recommendation were 142(76.3%) in men and 18(75%) of women. By the health risk appraisal, it was suggested that smoking cessation program, drinking counselling, exercise prescription, stress management, and weight control program should be conducted effectively for the high risk group.

Before and after conducting the health promotion program by group occupational health service during 5 years, we surveyed knowledge, attitude and practice about general health (30 items) and occupational health(30 items) among 25 small and medium scale industry workers(before: 355 workers, after: 279 workers) for evaluation of effectiveness. The scores of knowledge for smoking, drinking, cholesterol, mental stress, management of hypertension, and risks in younger or women workers were significantly increased after conducting group occupational health service. The scores of attitude for controlling of fatty food consumption and cleaning workplace and bathing for health and that of practice for taking the periodic health examination and checking blood pressure were significantly increased but most of items in attitude and practice didn't be changed after services. According to sex, the scores of men were significantly increased in knowledge of general health, but there were not significant differences in age, job status and work duration group. In conclusion, through the group occupational health service during 5 years, only the scores of knowledge in general health were increased. It suggested that the effective program which can change workers' attitude and practice for health promotion, should be developed and conducted in small and medium scale industry workers.

Objective North Korean defectors (NKDs) have experienced substantial difficulties during the migration and settlement in South Korea. They have a high prevalence of depression, post-traumatic stress disorder, and suicidal behaviors. The high prevalence of mental disorders among NKDs can lead to a high suicide rate. However, there are no suicide prevention programs for NKDs. This study aims to customize a suicide prevention program with content suitable for NKDs’ particular circumstances.Methods A multidisciplinary research team developed this program based on domestic and international gatekeeper training programs for suicide prevention and articles related to suicide prevention.Results We developed a multi-part gatekeeper training program, “Suicide CARE for NKDs.” In the “Introduction,” trainees learn about the need for the program and its importance. In “Careful observation,” trainees learn to recognize linguistic, behavioral, and situational signals of suicide risk. In “Active listening,” trainees learn how to ask about suicidal thoughts and to listen empathetically. In “Risk evaluation and expert referral,” trainees learn to evaluate suicide risk and to connect NKDs with institutes or services.Conclusion We expect this program to become useful for training gatekeepers to prevent suicide among NKD. A future follow-up study is needed to confirm the efficacy of the program.

We would like to report a case of leiomyoma of the ovaries in a dog. Leiomyoma is commonly seen in the vagina in dogs. However, it is a very rare neoplasm in the ovaries. As there have only been a few reported cases, this report provides valuable information on veterinary medicine and pathology. Masses found in the ovaries need to be differentiated from other ovarian tumors. Therefore, we describe the gross, histopathological, and immunohistochemical features of a case of ovarian leiomyoma in a 10-year-old female Yorkshire Terrier dog. The mass on the right of the uterus was found accidentally by pelvic ultrasonography. Laparatomy revealed a large multi-nodulated ovarian mass. Grossly, cut surfaces of the mass showed multiple firm whitish nodules in the cortex and bloody loose connective tissue in the medulla. Histopathologically, the cortex of the mass was composed of spindle cells forming interlacing fascicles. The cells had elongated, blunt-ended nuclei and eosinophilic cytoplasm as detected by hematoxylin and eosin staining. Immunohistochemical stained sections were immunoreactive for α-smooth muscle actin and desmin but negative for vimentin and S-100. Therefore, differential diagnosis confirmed leiomyoma based on morphology and positive staining for α-smooth muscle actin and desmin.

<P>Oligodendrocytes are myelin-forming cells in the central nervous system. Research into the effects of aging on oligodendrocyte protein expression remains limited. The present study aimed to determine the alterations in oligodendrocyte-specific protein (OSP) expression in the gerbil hippocampus at 1, 2, 3, 4, 6 and 24 months of age with western blot and immunohistochemistry analyses. OSP expression levels in the hippocampus were highest at 6 months of age. OSP immunoreactivity was identified in numerous cell bodies at 1 month, although the number of OSP immunoreactive cells was different according to hippocampal subregion. The number of OSP immunoreactive cells significantly decreased at 2 months and, thereafter, numbers decreased gradually. The detection of OSP immunoreactive fibers was negligible in all layers in the hippocampal subregions until 4 months. OSP immunoreactive fibers were abundant at 6 and 24 months, although the fiber distribution patterns in the CA1-3 areas and dentate gyrus were different. The results demonstrated that OSP expression in the gerbil hippocampus was age-dependent. The detection of OSP immunoreactive cell bodies and fibers was significantly different according to the layers of hippocampal subregions, indicating that myelination may be continuously altered in the hippocampus during normal aging.</P>

Objective The aim of this study was to evaluate differences in psychopathology between offspring of parents with bipolar I disorder (BP-I) and those with bipolar II disorder (BP-II). Methods The sample included 201 offspring between 6 and 17 years of age who had at least one parent with BP-I or BP-II. The offspring were diagnostically evaluated using the Korean Kiddie-Schedule for Affective Disorders and Schizophrenia-Present and Lifetime Version. Psychopathology and Clinical characteristics were evaluated, including lifetime DSM-5 diagnoses, depression, and childhood trauma. Lifetime DSM-5 diagnoses were also compared between schoolchildren aged 6 to 11 years and adolescents aged 12 to 17 years. Results In lifetime DSM-5 diagnoses, offspring of parents with BP-I had significantly increased risk of developing MDD and BP-I than those with BP-II. Regarding clinical characteristics, ADHD rating scale and childhood trauma scale were significantly higher in offspring of parents with BP-I than that in those with BP-II. Conclusion The present study supports that BP-I may be etiologically distinct from BP-II by a possible genetic liability. Our findings indicate that additional research related to bipolar offspring is needed to enhance understanding of differences between BP-I and BP-II.
