Purpose:
To verify the anti-microbiotic activity and to develop eco-friendly surface disinfectants using the Opuntia ficus-indica extract.
Methods:
The stem and fruits of the Opuntia cultivated in Jeju Island were extracted with hot water, 70% EtOH and 100% MeOH, respectively. To examine the antimicrobial activity of the extracts, gram positive bacteria (Bacillus subtilis, Staphylococcus aureus), gram negative bacteria (Escherichia coli, Salmonella typhimurium), yeast (Candida albicans), mold (Aspergillus flavus) and antibiotic resistant bacteria (E. coli, S. aureus) were measured to form a clear zone.
Results:
The antibacterial activity of the fruit extract was higher than that of the stem extract, and the antibacterial activity of the 100% MeOH (FM) extract and the 70% EtOH (FE) extract of the palm cactus fruit was suitable for the surface disinfectant overall, and clear-zone formed even at relatively low concentrations (250 mg/mL). The FM and FE have antibacterial activity against various bacteria, therefore they can be used as disinfectants.
Conclusion
The antimicrobial activity of Opuntia ficus-indica extract from Jeju Island by stem and fruit was determined at relatively low concentrations (250 mg/mL). The Opuntia ficus-indica extract will be useful for surface disinfectants dissolving the patients’ bath, oral gargling, and powdered powder in water or ethanol in appropriate concentrations.

Gastric cancer is a malignancy with high incidence and mortality worldwide. In gastric cancer, epithelial-mesenchymal transition (EMT) and metastasis further increase the mortality rate. Trefoil factor 1 (TFF1) has been reported as a protective factor in the gastric mucosa. In this study, TFF1 inhibited the migration and invasive capability of gastric cancer cells. Elevated TFF1 levels induced the expression of E-cadherin, the epithelial marker, and reduced the expression of N-cadherin, vimentin, Snail, Twist, Zinc finger E-box binding homeobox (ZEB) 1 and ZEB2, well-known repressors of E-cadherin expression. In addition, the expression of matrix metalloproteinase (MMP)-2, MMP-7 and MMP-9, which are major markers of cancer metastasis, was suppressed by TFF1. Upregulation of TFF1 inhibited TGF-β, a major signaling for EMT induction, and the phosphorylation of Smad2/3 activated by TGF-β in AGS cells. In conclusion, TFF1 inhibits EMT through suppression of TGF-β signaling in AGS cells, which might be used in therapeutic strategies for reducing metastatic potential and invasiveness of these cells.

Twin pregnancies are at substantially higher risks for premature delivery than singleton pregnancies. This further increases their risk of perinatal and infant mortality. Recently there has been a marked increase in multiple pregnancies as a direct result of assisted reproductive technology. Cervical incompetency is a condition in which a pregnant woman's cervix begins to dilate and efface before her pregnancy has reached term. And multiple pregnancies and pregnancies by in vitro fertilization (IVF) have been increasing the risk of cervical incompetency. In twin pregnancy during preterm delivery, successful delayed-interval deliveries may improve the neonatal outcomes of the second fetus. We report a case of a delayed interval delivery in twin pregnancy of incompetent of cervix with an interval of 28 days after 3rd emergency cerclage.

The purpose of this study was to evaluate trends in the sources of dietary sodium intake in a representative Korean population in the Korea National Health and Nutrition Examination Survey (KNHANES) conducted in 1998, 2001, 2005, 2007, 2008, 2009, and 2010. The study consisted of 53,570 men and women aged 7 years or older participating in the KNHANES during the corresponding years. Overall sodium intake and the mean percent contribution of each dish and food group to dietary sodium intake across 1998-2010 were calculated. The means of sodium intake ranged between 4,572.6-5,498.9 mg/d across 1998-2010. The major dish groups contributing to dietary sodium intake were kimchi (1,154.8-1,521.2 mg/d), noodles and dumplings (505.3-760.5 mg/d), soups (465.3-714.8 mg/d), and stews and casseroles (387.0-579.8 mg/d). The combined mean percent contribution from the top four dish groups contributing to dietary sodium intake showed a slight decrease over the period; 64.4% in 1998, 64.5% in 2001, 59.3% in 2005, 58.2% in 2007, 56.3% in 2008, 56.7% in 2009, and 54.4% in 2010. The major food groups contributing to dietary sodium intake were seasonings (1,852.9-2,435.9 mg/d), vegetables (1,425.6-1,792.1 mg/d), grains (482.2-778.1 mg/d), and fish and shellfish (257.2-351.4 mg/d). In addition, the combined mean percent contribution from the top four food groups showed a slight decrease over the period; 92.8% in 1998, 93.2% in 2001, 93.8% in 2005, 92.1% in 2007, 91.7% in 2008, 90.9% in 2009, and 90.7% in 2010. In summary, we did not observe a reduction in dietary sodium intake over time, however, the percent contributions from the top major dish groups or food groups to dietary sodium intake showed a decrease over the last decade.

Journal of Dental Hygiene Science 2017;17(5):454-461
The purpose of this study was to confirm the relevance of dental health capacity and pulmonary function status. The subjects of this study were adults aged 40 years and older, who participated in pulmonary function and oral examinations. The data used for this study were raw data from the sixth Korea National Health and Nutrition Examination Survey (2013~2015). Statistical analysis was performed by analysis of complex sample survey data. The results were as follows: First, restrictive and obstructive patterns were more prevalent among males than females. They were even worse in older subjects. Approximately 67% of smokers had obstructive pattern. Second, there was a relevance between dental health capacity and pulmonary function status. The functioning teeth index, number of present teeth, and number of sound teeth (ST), which are indicators of dental health, declined with decreased pulmonary function. The number of missing teeth (MT) increased as the pulmonary function deteriorated (p<0.05). Third, the relevance between dental health capacity and pulmonary function status after stratifying the life-long smoking experience was statistically significant in the tissue health (T-health) index and ST among non-smokers. The relevance between dental health capacity and pulmonary function status after stratifying the life-long smoking experience was statistically significant (p<0.05) for the T-health index, ST, and MT among smokers. However, there was no relevance between dental health capacity and pulmonary function status after stratifying the life-long smoking experience and adjusting confounding variables. In conclusion, there was a relevance between dental health capacity and pulmonary function status after confounding variables were adjusted. However, there was no relevance between dental health capacity and pulmonary function status after stratifying the life-long smoking experience and adjusting confounding variables.

Cross-reactive carbohydrate determinants (CCDs) are simple carbohydrates linked to amino acid chains; they are found in pollens, vegetable foods, insect, and Hymenoptera venoms and are broadly cross-reactive with CCD-specific IgE antibodies. A man in his fifties was evaluated using a multiple allergen simultaneous test–immunoblot assay. On the PROTIA Allergy-Q 64 inhalant panel (ProteomeTech, Korea), reactions to 37 of 59 antigens were observed except mammalian antigens, and cross-reactivity owing to anti-CCD antibodies was suspected. After ProGlycAn CCD-blocker (ProGlycAn, Austria) treatment, the patient exhibited no response to CCD allergens, and the number of allergens showing positive reactions was reduced to 15. We further tested a total of 7 samples from patients who were suspected to have CCD-related cross-reactivity. For these 8 patients, the average number of positive reactions to allergens was reduced from 33 (range 24-36) to 8 (range 0-19) after CCD-blocker treatment. We concluded that CCD-blocker treatment in sample with anti-CCD antibodies can reduce the false positive reponse and provide more specific information about allergens.

BACKGROUND/AIMS: Colorectal cancer and thyroid cancer are common diseases with relatively higher survival rates compared with other cancers. The number of patients identified with colorectal cancer or thyroid cancer who develop multiple primary malignancy during long-term follow-up is increasing with advances in diagnostic techniques and treatment modalities. However, the association between colorectal cancer and thyroid cancer is uncertain, and few data have been reported in Korea. This study examined the association between thyroid cancer and colorectal neoplasm. METHODS: We retrospectively investigated 363 patients who underwent a colonoscopy, among patients diagnosed with thyroid cancer between January 2004 and December 2008 at Samsung Medical Center. The control group was comprised of 2,494 patients who underwent screening colonoscopy for the first time within the study period at the center for health promotion at Samsung Medical Center between March 2004 and December 2005. RESULTS: The detection rates in patients with thyroid cancer were 4.7% (17/363) for advanced adenomas and 2.8% (10/363) for colorectal cancer. In the control group, it was 3.2% (79/2,494) for advanced adenomas and 0.3% (7/2,494) for colorectal cancer. A multivariate analysis revealed that the presence of thyroid cancer had an odds ratio of 1.893 (95% confidence interval, 0.868-4.128, P=0.109) in favor of finding at least one advanced colorectal neoplasm. CONCLUSIONS: The results indicate that thyroid cancer is not associated with advanced colorectal neoplasm. Survivors of thyroid and colorectal cancer live longer and hence are at risk for second primary cancers. Therefore, further studies that prospectively evaluate the association between thyroid cancer and colorectal advanced neoplasm are needed.
