The purpose of this study is to evaluate nutritional status of ascorbic acid in 96 Korean female college students. Dietary intake level was estimated with three day diet records. Serum ascorbic acid were analyzed with fasting blood. Nutrient intakes was calculated using three different food composition databases ; analysis data of cooked food items ; analysis data of raw foods ; published food composition table. Ascorbic acid intake levels calculated with different food composition databases differed by 15% Using analysis data of cooked foods resulted in the lowest intake level 49.26 mg per day. Main sources of ascorbic acid investigated were Cheju mandarin orange juice and hard persimmon orange juice and Kimchi. Mean value of serum ascorbic acid level was 1.04 mg/dl and 4.2% of subjects were in marginal risk or deficient range. It was found to significantly correlate asscorbic acid intake with serum ascorbic acid content. Correlation coefficient with results calculated using analyzed data was higher than that using published data. Serum levels and mean daily intake levels of ascorbic acid in the subjects were significantly correlated. From these results it is concluded that ascorbic acid content of cooked foods should be included in the Food Composition Tables in Korea. Korean female college students were in lower risk of ascorbic acid deficiency.

This study examined to find out the relationship between nutritional knowledge and food habit of the students majoring food & nutrition(218 students) and the students majoring Korean oriental medicine(286 students). The results of this study are as follows; 1)The intake of vegetable and dairy products is high for the students majoring food & nutrition(p＜0.01), and the intake of instant food is low for the students majoring Korean oriental medicine(p＜0.01). 2)In the value of diet, the ratio which acknowledges the importance of the relationship between the diet and the nutrients is high for the students majoring food & nutrition (p＜0.01), and the ratio which acknowledges the diet as the way to remove hunger or to enjoy eating is high for the students majoring Korean oriental medicine(p＜0.01). The ratio of the students who acknowledge taste, nutrition and preference as the important factors in selecting foods is high for the students majoring food & nutrition(p＜0.01). The ratio of regularity in each meal, consuming time, and the food quantity is high for the students majoring Korean oriental medicine(p＜0.01). 3)The total score of 20 inquiring items about nutritional knowledge is high for the students majoring food & nutrition(p<0.01), and especially the mark is high in such items inquiring the relationship between animal fat and nutrition(p<0.01), the relationship between water and obesity(p<0.05), the relationship between cholesterol and food(p<0.01), the recommended energy quantity(p<0.05), and the vitamin B group (P<0.01). According to this study, it is hard to determine that there is inevitable positive relationship between diet habits and nutritional knowledge. The students majoring food and nutrition know better than the students majoring Korean oriental medicine about the relationship between diet, health and nutrients however they can not practice what they blow when selecting foods. On the other hand the students majoring Korean oriental medicine show lower marks in food habits and nutritional knowledge than those of the students majoring food and nutrition; however, they show higher marks in practicing regular diet. According to this result it is necessary to increase the subjects related nutrition in the curriculum not only lot the students majoring food & nutrition to practice their nutritional knowledge in their actual life but also for the students majoring Korean oriental medicine to obtain correct nutritional knowledge and information.

The purpose of this study is to investigate the effects of the herbal Chokong pill (hereafter HCKP) on the liver cell and enzyme activities of serum in rat. HCKP were mixed with pickled black soybeans and five different kinds of medicinal herbs (Rhynchosia nulubilis, Glycyrrhiza uralensis, Zizyphus vulgaris, Atractylodes macrocephala K., Astragalus membranaceus and Cornus officinalis). Four groups of male Sprague-Dawley rats were fed by different diets for 9 weeks: normal diet (Nor), high-fat diet (HF), high-fat diet supplemented with 1% (T1) and 5% (T5) HCKP powder, respectively. Depending on the presence of HCKP in high fat diet, the activities of the blood serum GOT and GPT were decreased. GOT and GPT activities of T1 and T5 were decreased 6.1%, 17.8% and 25.4%, 32.4% compared with HF. On microstructure observing through the transmission electron microscope (TEM) of liver cell, in normal group, a normal large and clear nucleus, rough endoplasmic reticulum (RER) and mitochondria possessing well-defined double outer-limiting membranes were found. However, in HF, it was hard to observe the microstructures in cytoplasm, because of too many fat granules. It showed severely damaged cell, pyknotic nucleus, swollen disintegrating RER and mitochontria loosing the cristae. In T1, there were more repaired liver cells and less fat granules than HF. In T5, there were much less numbers and smaller size of the fat granules than T1, and the morphology was similar to normal cell.

Purpose: The radial forearm fasciocutaneous free flap is currently considered as the ideal free flap for reconstruction of mucosal and soft tissue defects of the palate. But the availability of stably attached oral and nasal mucosal lining is needed. In addition to this, for better operation field, operating convenience and esthetics, we planned a prelaminated radial forearm free flap. Methods: A 64-year-old male patient was admitted due to a $4{\times}4.5cm$ full through defect in the middle of the hard palate caused by peripheral T cell lymphoma with actinomycosis. In the first stage, the radial forearm flap was elevated, tailored to fit the hard palate defect, and then it positioned up-side down with split thickness skin graft. Two weeks later, the prelaminated radial forearm free flap was re-elevated and transferred to the palatal defect. One side covered with grafted skin was used to line the nasal cavity, and the other side (the cutaneous portion of the radial forearm flap) was used to line the oral cavity. Results: The prelamination procedure was relatively easy and useful. The skin graft was well taken to the flap. After 2nd stage operation, the flap survived uneventfully. There was no prolapse of the inset flap into the oral cavity and the cutaneous portion of the flap was mucosalized. The procedure was very successful and the patient can enjoy normal rigid diet and speech. Conclusion: The use of prelaminated radial forearm free flap for hard palate reconstruction is an excellent method to restore oral function. Based upon the result of this case, microvascular free flap transfer with prelaminated procedure is a valid alternative to the prosthetic obturator for palatal defect that provides an improved quality of life. It should be considered as an integral component of head and neck cancer therapy and rehabilitation.

Periodontal disease is characterized by inflammation and subsequent loss and/or damage to tooth-supporting tissues such as bone, cementum,and periodontal ligament. Periodontal ligament and cementum are the key tissues in the initial process of regeneration following periodontal disease. Therefore, studies on cementoblasts, which form cementum are emphasized. It is still unclear which cells cementoblast differentiate from. This study was conducted under the hypothesis that PDL fibroblast can differentiate into either cementoblast or osteoblast depending on the conditions of surrounding tissue. Clinically, with excessive traction force of orthodontic appliances or excessive occlusion hypercementosis is observed, and this has been confirmed histologically. Consequently, activation of cementoblast can be expected in rats when mechanical stimuli are given to PDL fibroblast. Therefore, the purpose of this article is to prove that PDL fibroblast differentiates into cementoblast in rats under mechanical stimuli using histologic and molecular methods. In this study, twenty rats were given hard diet. Ten of them were sacrificed after 1 week, and the others were sacrificed after two weeks. Slides were made from tooth specimen, and they were studied under the microscope. In addition, PDL fibroblast and cementum from the extracted teeth were analyzed with Northern blotting. In histologic examination, as time passed, PDL fibroblast migrated to the dentin side, differentiated into cementoblast, and formed new cementum. In Northern blotting, it was found that mRNA expression of cementoblast-specific proteins such as BSP, OC, OPN, and type I collagen were more prominent in rats sacrificed after 2 weeks of hard-diet than rats sacrificed after 1 week. From these findings we can conclude that PDL fibroblast can differentiate into cementoblast under mechanical stimuli. We think that 'Rat Models' used in this study will be beneficial to future studies regarding cementoblast.

The objective of this experiment was to determine the effects of different levels of refined cod liver oil (RCLO) on laying performance, n-3 polyunsaturated fatty acids composition (n-3 PUFAs) and the organoleptic evaluation of duck egg yolks. A total of 180 30 wk old laying Tsaiya ducks, at the beginning of peak production, were allotted into 6 treatments with 3 replicates each. Ducks were fed one of the 6 experimental diets, supplemented with 2% tallow (control) and graded levels of RCLO at 2, 3, 4, 5, and 6% to a corn-soybean diets, respectively, for 6 wks. All of the experimental diets were formulated to be both isocaloric and isonitrogenous. Feed and water were supplied ad libitum throughout the experimental period. The results indicated that the RCLO supplementation levels did not affect (p>0.05) egg production, egg mass, feed intake, feed efficiency or body weight change. Egg weight was the lightest when the ducks received the 6% RCLO diet. The eicosapentaenoic acid, docosahexaenoic acid, and total n-3 PUFAs contents in the yolks increased with increasing RCLO supplementation. The taste and general acceptability of the hard-boiled eggs were not significantly different among the treatments. However, a fishy flavor was much higher when ducks were fed diets supplemented with 5% and 6% RCLO diets.

This study aimed at examine dietary attitude, eating behavior and food preferences of children in child care center. The children involved in this study were 153 boys and 134 girls, aged 3 to 6 years old. The eating frequency of breakfast and the number of meal times a day were significant difference according to sex(P<0.01). Reason for skipping breakfast was ‘no appetite’(49.3%). It was found that 51.5% of the children belonged to ‘fair’ in food habit score, while children in ‘poor’ and in ‘excellent’ were 25.0% and 9.7% respectively. There was no significant difference in food habit score between boys and girls. Their preferred staple foods were ‘cooked rice’ and ‘Chajangmyon’, their preferred soup was ‘seaweed soup’. Also, their most preferred side dishes with animal foods were ‘fried chicken’ and ‘Bulgogi’. The preference of ‘hard boiled soybean curd’ and ‘pan fried soybean curd’ among the side dishes with vegetable foods were significant according to the obesity index(P<0.05). Children preferred side dishes with animal foods to those with vegetable foods. First considered item in meal preparation was child's favorite(58.1%). Mother's response to child's unbalanced diet was ‘trying to persuade the child’(56.6%). It was significant according to mother's occupation(P<0.01). The nutritional management program at child care center is required to enhance the nutritional status of children. Also the nutritional education for the children and their meal planners is required for better growth and health promotion of preschool children.

In recent years, the numbers of the orthodontic dental patients have been rapidly increased in adolescent or young adult aged generation. It has been well known that it would be very hard to control the oral hygiene cares for orthodontic applied dental patient because of the complexity of the appliance. So the caries prevalence of the orthodontic dental patients would be higher than non-appliance persons, and it might be easy to cause the dental caries especially on the labial or buccal surface of the tooth through equipping the fixed type appliance with a long period, even though the alignment of the teeth would be arranged well. So, the massive preventive program for preventive dentistry should be needed for the dental patients for orthodontic treatment, in order to protect the dental caries and the periodontal disease for them. But, lots of the dentists or dental hygienists sometimes neglect of this point for preventive dental cares orthodontic dental patients, or do not know the importance and how to manage the skill for the preventive dental works in clinical. In this article, it will be introduced the basic theories and skills for preventive cares as tooth-brushing instruction, fluoride topical application and pit and fissure sealant, scaling and professional mechanical tooth cleansing and the diet control, for the dental patients with the fixed type of the orthodontic appliance, in case by case.

Objectives: The objective of this study was to review clinical studies conducted over the last ten years that investigated weight or fat loss interventions that can preserve muscle or fat-free mass in Sarcopenic obesity Methods: PubMed, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), Research Information Sharing Service (RISS) and Korea Studies Information Service (KISS) were searched for Randomized clinical trials that had investigated all-type of interventions on the management of sarcopenic obesity from October 2013 to September 2023. Results: A total of 14 studies met all the inclusion criteria. Interventions that increase muscle mass while reducing body fat at the same time included resistance training (including using elastic bands) and whole-body electromyostimulation(WB-EMS) in exercise intervention and Hypocaloric high-protein diet in nutritional intervention, exercise and nutritional combined intervention, and combination intervention of electrical acupuncture and amino acid supplementation. Among them, the most positive method of changing the body composition in sarcopenic obesity was the electric acupuncture and amino acid supplements. Conclusion: Varying diagnostic criteria and management interventions for sarcopenic obesity in the included studies made it hard to maintain homogeneity across the studies. Well-defined criteria for diagnostic sarcopenic obesity should be considered. In addition, since all of the interventions examined did not show sufficient clinical effectiveness, follow-up studies are needed to confirm effective interventions for sarcopenic obesity patients in the future.

The flap considered at first for the reconstruction of large maxillary defect, especially mid-face defect, is scapular free flap, because it provides ample composite tissue which can be designed 3-dimensionally for orbital, facial and oral reconstruction. In case of maxillary defect involving hard palate, however, this flap has some limitations. First, its bulk prevents oral function and physio-anatomic reconstruction of nasal and oral cavity. Second, mobility and thickness of cutaneous paddle covering the alveolar area reduce retention of tissue-supported denture and give rise to peri-implantitis when implant is installed. Third, lateral border of scapula that is to reconstruct maxillary arch and hold implants is straight, not U-shaped maxillary arch form. To overcome these problems, new concept of step prefabrication technique was provided to a 27-year-old male patient who had been suffering from a complete hard palate and maxillary alveolar ridge defect. In the first stage, scapular osteomuscular flap was elevated, tailored to fit the maxillary defect, particulated autologous bone was placed subperiosteally to simulate U-shaped alveolar process, and then wrapped up with split thickness skin graft(STSG, 0.3mm thickness). Two months later, thus prefabricated new flap was elevated and microtransferred to the palato-maxillary defect. After 6 months, 10 implant fixtures were installed along the reconstructed maxillary alveolus, with following final prosthetic rehabilitation. The procedure was very successful and patient is enjoying normal rigid diet and speech.
