The aim of this study was to examine the factors influencing perceived oral health in elderly individuals residing in the community. This study used raw data from the Korea community health survey, 2016. Of the 64,223 participants that were elderly (aged ≥ 65 years), 61,280 (95.4%) were included for analysis. Self-rated oral health was the dependent variable and 6 independent variables including age, gender, type of area of residence (metropolitan or provincial), educational level, income, and living status with spouse were assessed. Oral function was studied based on mastication, pronunciation, and use of dentures, and oral health behavior included brushing teeth after breakfast, after lunch, after dinner, and before sleep). The EQ-5D questionnaire measured health-related quality of life (mobility, self-care, usual activities, pain/discomfort and anxiety/depression). Among the general characteristics, age, gender, educational level, income, and living status with spouse were the factors that affected self-rated oral health. Mastication, pronunciation, use of dentures, and brushing after lunch, dinner, and before sleep were the factors that influenced self-rated oral function. All domains of the EQ-5D (pain/discomfort, mobility, self-care, usual activities, and anxiety/depression) were factors that affected self-rated oral health. The results of the current investigation suggest that the development of management and education strategies for oral health promotion in the elderly, should focus on improving oral function and oral health behavior, taking into account the socio-economic and demographic characteristics that have been shown to be associated with poor self-rated oral function.

BACKGROUND: Headache is a common symptom. It has not proved useful methods that the physician evaluated the alert patient who had headache. It needs the presence of predictors of intracranial pathology(ICP) which serves as influential factors in the indication of evaluation and hospitalization of patients. METHOD: So, in order to identify such factors, patient records were retrospectively analysed. 168 patients with the chief complaint of headache presented to the Emergency Department of Chonnam University Hospital during the period from January 1, 1995 to December 31, 1997. All were in an alert mental state and had no evidence of trauma and intoxication. RESULTS: 14 cases(8.3% revealed ICP. 41 cases(24.4% revealed systemic disease. The remainder of cases were divided among unclassified headaches(61 cases, 36.3%, tension headaches(30 cases, 17.9%, and migraine(22 cases, 13.1%. Comparison of ICP-positive and ICP-positive cases revealed that ICP-Positive Patients could be categorized by the following findings: (1) Presence of the focal sign through neurological examination, (2) age greater than 55 years, (3) presence of associated symptoms, (4) acute headache. These four manifestations were proven to be statistically significant as predictors of ICP. CONCLUSION: Although the positive predictive value of the above criteria is not perfect for the prediction of ICP, they are worthy of clinical consideration in alert patients presenting with headache.

Soft denture liners or conditioners may be valuable therapeutic materials. The life of these liners is short and varies, but it can be extended by the use of a mono-poly(polymethyl methacrylate coating material). This study determined whether coating three temporary soft denture liners with mono-poly affected the resiliency of soft liners, and evaluated the ability of mono-poly to prevent water absorption and alcohol loss from the underlying soft liners. 20x12mm cylindrical specimens of Coe-Soft, Soft-Liner, Coe-Comfort soft lining materials were made and divided into two groups of mono-poly uncoated(control) and mono-poly coated specimens. Specimens were immersed in water and compressed on an instron universal testing machine and weighted at initial, 24 hours, 1 week, 2 weeks, and 4 weeks. resiliency was determined by measuring the energy absorbed by the soft liners when stressed to a specific yield point. Mono-poly coating significantly increased the resiliency of the Soft-Liner, but had no effect on the other soft liners. Among the 3 soft liners, Soft-Liner showed the hightest resiliency and modulus of elasticity. The weight loss in Soft-Liner was the least among the 3 liners, and the weight loss in Coe-Soft was decreased by monopoly coating.

BACKGROUND: Both atrophic gastritis and intestinal metaplasia may progress to gastric dysplasia. This study aimed to analyze the factors influencing progression of atrophic gastritis and intestinal metaplasia to dysplasia. METHODS: People diagnosed with atrophic gastritis and intestinal metaplasia for the first time received a follow-up endoscopy and were investigated for the cumulative incidence rate of gastric dysplasia by age, gender, smoking habit, alcohol intake, rice consumption and family history of stomach cancer. RESULTS: The cumulative incidence rate increased with age, consuming > or =3 bowls of rice per day and family history of stomach cancer. Multivariate analysis showed that the cumulative incidence rate of gastric dysplasia increased in subjects >61 years (RR=2.54, P=0.014), in those consuming > or =3 bowls of rice per day (RR=1.46, P=0.021) and in those with a family history of stomach cancer (RR=1.31, P=0.037). CONCLUSIONS: More active management, such as intensive endoscopic follow-up examinations, lifestyle change and education regarding gastric dysplasia, are required in those older than 61 years, having a higher intake of grain or with a family history of stomach cancer.

To analyze the effects of the characteristics of the systolic anterior motion(SAM) of the mitral valve on the left ventricular outflow pressure gradient and to determine the relation between the anatomical characteristics of the left ventricle and the left ventricular outflow pressure gradient, mitral valve and left ventricular M mode echocardiogram and continuous wave Doppler echocardiogram of the left ventricular outflow tract were recorded in 7 patients with hypertrophic obstructive cardiomyopathy(HOCM), aged 19 to 66 years(mean 37 years). Mitral-septal distance at the closest apposition(S-SAM;1.1+/-2mm), duration of mitral-septal apposition(89+/-20 msec), time interval from the peak of the R-wave to initial apposition of the mitral valve against the interventricular septum(R-SAM interval ; 222+/-32 msec) and left ventricular posterior wall thickness(LVPWT; 1.1+/-0.5mm) were observed on mitral valve and left ventricular M-mode echocardiograms and peak flow velocity in the left ventricular outflow(V-LVOT; 3.5+/-1.5 m/sec) was measured from the Doppler echocardiograms of the left ventricular outflow tract. V-LVOT was correlated significantly with degree of mitral-septal apposition(r=-0.70, p<0.05), duration of mitral-septal apposition(r=0.74, P<0.05), R-SAM interval(r=-0.80, p<0.05) and LVPWT(r=0.78, p<0.05). These results suggest that the closer apposition of mitral valve against interventricular septum, the more prolonged mitral-septal apposition, the earlier onset of SAM of the mitral valve and the thicker the left ventricular posterior wall, the more increase the LV outflow pressure gradient in HOCM.

We investigated the effects of panretinal photocoagulation (PRP)on macular microcirculation in diabetic retinopathy. PRP using argon blue green laser was performed in 23 eyes of 15 patients with early proliferative diabetic etinopathy and very severe nonproliferative diabetic retinopathy without significant macular edema. The changes in volume, flow, velocity of macular microcirculation were measured before PRP, 1 hour, 1 day, 1 week, and 1 month following PRP, using Heidelberg Retina Flowmeter(HRF). Mean volume, flow, velocity of macular microcirculation decreased to a maximal degree 1 hour following PRP, from 14.87+/-0.40, 387.45 +/-101.40, 1.40+/-0.28(before PRP)to 12.44+/-1.39, 347. 33+/-100.39, 1.27+/-0.34(p<0.05). From 1hour to 1 month after PRP, macular microcirculation gradually increased. However, throughout this period, all parameters of macular microcirculation remained lower than pre-PRP level(p<0.05). Our study suggests that panretinal photocoagulation reduces the macular microcirculation in diabetic retinopathy.

Growth under conditions of iron-restriction and the production of siderophore was examined in Vibrio mimicus ATCC 33653. This strain grew and multiplied in the presence of the high-affinity iron chelators ethylenediamine-di (o-hydroxyphenylacetic acid). Chrorne azurol S (CAS) agar and solution were used to detect the production of siderophore under these condition. Siderophore could be detected in the iron-rcstricted culture supernatants. The siderophore was extracted from iron-restricted culture supernatants by phenol-chloroform-ether method and purified by Dowex ion-exchange and Sephadex G-25 gel filtracton chromatography. The purified siderophore was confirmed by paper chromatography and HPLC. The Purified siderophore enhanced the growth of V. mimicus when the bacterium was grown in iron limited medium. Injection of both the siderohore and the bacteria to mice resulted in more rapid death than that of the only bacteria. However, the siderophore did not show lethality to mice and any toxicity to cell line like HeLa and U937.

Journal of the Korean Society for Microbiology 1999;34(5):423-433
A novel bacteriophage, designated as VPP97, that infects the strains of Vibiro parahaemolyticus (hallophilic, Gram-negative bacterium) isolated most commonly from marine environments, has been discovered, and several of its properties have been determined. The plaques were clear and sized 0.6-1.0 mm in diameter. The virion forms a single band on 70% sucrose gradient and p1.50 CsC1 gradient by sucrose gradient centrifugation and CsCI gradient centrifugation respectively. It has a hexagonal head and a relatively long tail, as shown by electron microscopy. Vibrio alginolyticus, Vibrio fluvialis and Vibrio furnissii were also sensitive to this phage It was almost totally inactivated at 70 degree C and at pH below 5 or over 10. The nucleic acid of VPP97 is composed of DNA. The VPP97 had 9 specific structural proteins sized between 21.5 kDa and 97.4 kDa on SDS-PAGE. When V. parahaemolyticus cultures were treated with either phage VPP97 or one of the several antibiotics for 2 hours, the viable number of V. parahaemolyticus treated with the phage VPP97 is lower than that treated with chloramphenicol, erythromycin or penicillin, but not lower than that treated with tetracycline. Mice that have responded to the phage treatment revealed the lower numbers of V. parahaemolyticus in small intestine and less damage on small intestine compared to the untreated mice. Therefore, we suggest that the phage treatment appears effective to the infection by V. parahaemolyticus.
