Purpose: Dental implants present several advantages over other tooth replacement options. However, there has been little research on masticatory function in relation to implant treatment. Therefore, the aim of the present study was to evaluate the improvement of masticatory function two weeks after implant restoration. Methods: Masticatory ability was evaluated with the subjective food intake ability (FIA) and objective mixing ability index (MAI) methods. Fifty-four subjects with first and second missing molars completed the study. The subjects were asked to complete a self-reported questionnaire about 30 different food items, and to chew wax samples 10 times both before and two weeks after implant restoration. A total of 108 waxes were analyzed with an image analysis program. Results: Dental implant restoration for lost molar teeth on one side increased the FIA score by 9.0% (P<0.0001). The MAI score also increased, by 14.3% after implant restoration (P<0.0001). Comparison between the good and poor mastication groups, which were subdivided based on the median MAI score before implant restoration, showed that the FIA score of the poor group was enhanced 1.1-fold while its MAI score was enhanced 2.0-fold two weeks after an implant surgery. Conclusions: Using the FIA and MAI assessment methods, this study showed that masticatory function was improved two weeks after implant restoration. In particular, the enhancement of masticatory function by implant restoration was greater in patients with relatively poor initial mastication than in those with good initial mastication.

The HACCP (Hazard Analysis Critical Control Point) system was applied to Handmade Rice Cakes. The main ingredients of rice cakes, work facilities and workers were provided from the KB company located in Seogye-dong Yongsan-gu, Seoul between September 12, 2012 and February 13, 2013. The manufacturing process chart was prepared by referring to the manufacturing process of rice cake manufacturers in general. Microbiological hazard analysis of the raw materials and after the steaming process of rice-cakes showed a safe result. On the other hand, the microorganism test on the manufacturing environment and workers suggested that the microbiological hazard can be reduced through systematic cleaning and disinfection, accompanied by improved personal hygiene based on hygienic education for workers on the management of microorganisms in the working area.

This research aimed to investigate the effect of business management of Korean restaurants on business performance and to propose an alternative. For this investigation, a survey was carried out targeting Korean restaurant managers in the capital area, and with 360 copies as sample, factor analysis, difference test, and multiple regression analysis were conducted. As a result of analysis, among the factors of business management of Korean restaurants, only information management and fund management appeared to have effects on both financial performance and nonfinancial performance. This means, in case of Korean restaurants, business performance can be improved by understanding every environment about food service management and customer demands, by investing fund in the right place, and by managing inefficient expenses. Therefore, it is most important for a Korean restaurant manager to cultivate knowledge in management and to put effort into cost-reduction of all employees.

Objectives : Secondary amenorrhoea is the absence of menses for three months in a woman with previously normal menstruation or nine months for women with a history of oligomenorrhoea. It can be caused by stress, extreme weight loss, and excessive exercise. The purpose of this study was to report the clinical effects of herbal medicine on secondary amenorrhoea.Methods : We employed oriental medical treatments; herbal - medication (Hyunburikyungtang gamibang), acupuncture and moxibustion. We treated the patients one or two times a month with oriental therapy method. They took medicine three times a day after a meal. During taking medicine, we let the patients avoid fatty food, flour based food and alcohol. We evaluated the status of the patient, on the basis of the state of menstration and F2 level of Yangdorak. Because we diagnosed the condition of patients with the pattern of liver depression and qi stagnation, so F2 level of Yangdorak was an important point of the diagnosis. Yangdorak machine was Tormeter Iw - zen at Towatech Co.,Ltd.Results : After taking treatment - several times acupuncture and moxibustion during some period and taking herbal-medicine, they had menstrain naturally without taking any hormone drug. Also the amount of menstration has gradually increased. The F2 level of Yangdorak returned to normal range. The feeling of cold on hands, feet and lower abdomen was much improved.Conclusions : Herbal medicine (Hyunburikyungtang gamibang) with oriental medical treatments, acupuncture and moxibustion was effective in the treatment of secondary amenorrhoea.

Objectives : Abnormal regulation of glucose and impaired lipid metabolism that result from a defective or deficient insulin are the key etiological factor in type 2 diabetes mellitus. The our study investigated the effects of Gamioknyeo-jeon (GO) on blood glucose and lipid metabolism improved by it in db/db mice (a murine model of type 2 diabetes mellitus).Methods : The animals were divided into 3 groups: Normal groups were not-treated C57BL/6 mice; Control groups were treated orally with DW in db/db mice; GO groups were treated orally with GO (200 ㎎/㎏/day) in db/db mice. After mice were treated with GO for 5 weeks, we measured AST, ALT, creatinine, BUN, body weight, food intake, blood glucose, insulin and lipid levels (total cholesterol, HDL cholesterol, and LDL cholesterol and atherogenic index(AI) and cardiac risk factor(CRF).Results : Serum AST, ALT, creatinine, BUN levels were not changed by GO do not show any toxic effects. GO groups were decreased in body weight, food intake and blood glucose level among compared to Control groups. Also, GO groups were found to have atherogenic Index and cardiac risk factor as well as lipid metabolism improvement (total cholesterol and LDL cholesterol decrease). Finally, GO groups were increased the insulin compared to Normal and control groups.Conclusions : We suggest that GO may have the control effects of diabetes mellitus by improving blood glucose control and lipid metabolism.

Objectives : The present study was designed to evaluate the protective effect of Allium tuberosum (AT) extract on atherosclerosis in LDL receptor knockout (LDLr KO) mouse fed western diet.Methods : The AT was extracted 70% ethanol. The experimental groups were divided with four groups of LDLr KO mice, one group fed a normal diet and the others fed a Western diets for 8weeks. Two Western diet groups were orally administered AT extract at dosage of 100 and 300 mg/kg body weight. The body weight and food intake were measured every day. We measured levels of alanine aminotransferase (ALT), aspartate aminotransferase (AST), triglyceride (TG), total cholesterol (TC), high-density lipoprotein (HDL), low-density lipoprotein (LDL), and Glucose in serum. Also, effect of AT extract performed using H&E staining.Results : The AT treatment groups showed decrease in body weight and food efficiency in comparison with control group. Blood biochemistry parameters such as TG, TC, LDL, and glucose levels were increased in control group, while AT treatment groups were reduced. Also, the increased levels of ALT and AST were improved by AT extract. We confirmed that the weights of liver, kidney, subcutaneous fat, epididymal fat, kidney leaf fat, and intraabdominal fat were change in LDLr KO mice treated AT extract. In addition, histopathological changes in liver and aorta were similar to normal group.Conclusions : Based on these results, the AT extract is considered to make prevention of atherosclerosis through reduction and functional improvement of the liver and vascular endothelial cells in the body fat accumulation and lipid content in LDLr ko mouse model.

Objectives : Anti-obesity drugs that have been developed so far have limited efficacies and considerable adverse effects affecting tolerability and safety. Therefore, most anti-obesity durgs have been withdrawn. We tried to develop anti-obesity agent by combinations from herbs that are used in food ingredients as well as in traditional medicines. Methods : The 80% (v/v) ethanol extracts from Bamboo (Phyllostachys pubescence) leaf (BL) and Scutellaria baicalensis (SB) and their 1:1 combination (BLSB) was evaluated on high fat diet induced obese mice compared to Omega-3 as a positive control. The mice were divided into six groups (n=5), one group fed a normal diet (ND), and the others fed a high fat diets for eight weeks. Two weeks after starting feeding the diets, the high fat diet groups were orally administered vehicle and Omega-3, BL, SB, and BLSB at dosage of 200 mg/kg/day for six weeks. All groups were assayed for body weights, food efficiency ratio, blood biochemistry parameters, and organic tissue weights. Results : BLSB group showed significant reductions in body weight gain and fat weights of liver and epididymal adipose tissue compared to BL or SB alone as well as control. Total-cholesterol and LDL-cholesterol levels significantly decreased, and HDL-cholesterol level increased. In liver tissue, macrovesicular steaotisis was remarkably improved and its fat cell size was also significantly decreased. Conclusions : These results suggested that a combination preparation of bamboo leaf and S. baicalensis has anti-obesity effect and have synergistic effect compared to bamboo leaf or S. baicalesis.

The callipyge mutation in sheep is a polar overdominant mutation that results in post-natal muscle hypertrophy in the loin and hindquarters of paternal heterozygotes (+/CLPG). Sheep that are homozygous for the callipyge allele (CLPG/CLPG) do not express the muscle hypertrophy phenotype, but serve as carriers for the mutation. Callipyge sheep are characterized by improved feed efficiencies and leaner carcasses. Leptin is a protein hormone secreted from adipose tissue and has been found to affect appetite and serve as an indicator of body fat mass. To date, very little knowledge is available as to the effect of the callipyge mutation on circulating leptin levels. Due to the interaction of leptin with feed intake and energy availability, and the fact that the majority of fetal growth occurs in late gestation, it is important to understand if the callipyge mutation interacts with leptin production in late gestational ewes. Therefore, our objective was to characterize serum concentrations of leptin in late gestational callipyge ewes vs. non-callipyge ewes. We evaluated genetically verified callipyge (n=6), homozygous (n=8) and normal (n=8) ewes weekly during the last eight wks of gestation through one wk post-partum. Weights were taken and body condition scores were assigned by trained personnel weekly. Blood was collected via jugular venipuncture on each sampling date and subjected to an ovine-specific leptin RIA. Genotype influences on peripheral concentrations of leptin were found to be highly significant (p=0.0005). Total leptin means for +/CLPG were 5.41${\pm}$0.40 ng/ml, CLPG/CLPG 8.11${\pm}$0.70 ng/ml, and +/+ 9.13${\pm}$0.93 ng/ml. Sampling date was also significant (p=0.0098) with all ewes showing a decrease in leptin levels throughout gestation and parturition. Using repeated measures, we were able to detect lower levels of plasma leptin in callipyge ewes, which may be indicative of their lower overall body fat content. These results indicate that the callipyge phenotype decreases the levels of adipose tissue and leptin production in gestating ewes.

This feeding trial was conducted to investigate the effects of Mentha arvensis (MA) and Geranium thunbergii (GT) in drinking water on physicochemical attributes, sensory qualities, proximate analysis and oxidative stability of broiler leg meat. One hundred and twenty broiler chicks were assigned to 1 of 4 dietary treatments for 5 weeks. The dietary treatments were 1) control, 2) T1 (0.1% 1 MA:1 GT), 3) T2 (0.1% 1 MA:4 GT), 4) T3 (0.1% 4 MA: 1 GT). The water holding capacity and cooking loss were improved (p < 0.05) in T2 and T3. The flavor, texture and acceptability of leg meat by consumers were significantly increased in T2 relative to the control (p < 0.05). The crude protein content was increased in T3 while the crude fat decreased in T2 (p < 0.05). Moreover, broilers supplemented with plant extracts had the lowest leg meat TBARS (thiobarbituric acid reactive substances) values after 2 weeks of storage as compared with the control. Total phenolic contents and 1-1-diphenyl 2 picrylhydrazyl (DPPH) activity were also better in the T2 group (p < 0.05) compared with the control, whereas 2,2-Azinobis-3 ethytlbenzothiazoline-6-sulfonic acid (ABTS⁺) remained unaffected. Overall, these results demonstrate that broiler drinking water with the inclusion of plant extract combination can be used to enhance the oxidative stability, shelf life and quality characteristics of broiler leg meat without compromising the growth performance.
