The writers have conducted the investigation to assess the nutritional status of young rural Korean children aged form 0 to 4 years old in August 1971. The survey areas were Kaejong-myon, Daeya-myon, Okku-gun, Jeonra-bukdo, Korea. These survey areas were typical agriculture plain areas. The total numbers of children examined were 2,706 comprising 1,394 male and 1,312 female. the weight, height, and chest circumference of children were measured and means and standard deviations were calculated for each measurement. In addition, the nutritional status of each child was classified by the four levels of malnutrition and the Gomez classification. The examination of red blood cell count, haematocrit value, and intestinal parasite infection were carried out at the same time. In general, recent work tend to suggest that environment influences, especially nutrition, are of great importance than genetic background or other biological factors for physical growth and development. Certainly the physical dimensions of the body are much influenced by nutrition, particularly in the rapidly growing period of early childhood. Selected body measurements can therefore give valuable information concerning protein-calory malnutrition. Growth can also be affected by bacterial, viral, and parasite infection. For the field workers in a developing country, therefore, nutritional anthropometry appears to be of greatest value in the assessment of growth failure and undernutrition, principally from lack of protein and calories. In order to compare and evaluate the data obtained, the optimal data of growth from the offspring of the true well-fed, medically and socially protected are needed, So-called "Standards" that have been compiled for preschool children in Korea, However, are based on measurement of children from middle or lower socio-economic groups, sho are in fact, usually undernourished from six months of age onwards and continuously exposed to a succession of infective and parasitic diseases. So that, the Harvard Standards which os one of the international reference standards was used as the reference standards in this study. Findings of the survey were as follows: A. Anthropometric data: 1) Comparing the mean values for body weight obtained with the Korean standard weight of the same age, the rural Korean children were slightly haevier than the Korean standard values in both sexes. Comparing with the Japanese children values, the rural Koran children were slightly haevier in male and in the infant period of female but lighter in female of the period of 1 to 4 years old than Japanese children. 2) Comparing the mean values for height obtained with the Korean standard height of the same age, the rural Korean children were taller than the Korean standard values except the second half of infant period in both sexes. Comparing with the Japanese children, the rural Korean children were slightly smaller than Japanese children except the first half of infant period in both sexes. 3)Mean values of chest circumference of rural Korean children obtained were less than the Korean standard values of the same ages in birth sexes. B. Prevalence of Protein-Calory Malnutrition: Children examined were divided into two groups, i. e. , infant (up to the first birthday) and toddler (1 to $ years old). 1) Percentage of four levels of malnutrition: a) when the nutritional status of each child was classified (1) by body weight value, the percentages for male and female of children attained standard value, the percentages for male and female of children attained standard growth were 52.8%(infant 83.3%, toddler 44.4%) and 39.7%(infant 74.5%, toddler 30.5%), the first level of malnutrition were 31.9% (infant 13.7%,toddler 36.9%) and 31.7%(infant 15.3%, toddler 36.0%), the second level of malnutrition were 12.3%(infant 1.7%, toddler 15.3%) and 23.3% (infant 7.7%, toddler 27.5%), the third level of malnutrition were 2.7%(infant 0.7%, toddler 3.2%) and 4.6%(infant 1.8%, toddler 5.3%) the fourth level of malnutrition were 0.3% (infant 0.7%, toddler 0.2%) and 0.7%(0.7% for infant and toddler) respectively.

(3) By body weight in relation to height, the percentages for male and female of children attained standard growth were 87.9%(infant 77.6%, toddler 87.9%) and 78.2%(infant 77.4%, toddler 78.2%), the first level if malnutrition were 12.2%(infant 18.4%, toddler 10.6%) and 18.2%(infant 17.9%, toddler 18.3%), the second level of malnutrition were 1.9%(infant 3.3%, toddler 1.5%) and 3.0%(infant 3.3%, toddler 2.9%), the third level of malnutrition of malnutrition were 0.1%(infant 0.7%, toddler 0%)and 0.3%(infant 1.5%, toddler 0%) respectively. b) When the nutritional status of each child according to the mother's aged mother (31 to 40 years old) and old aged mother (41 years of above) was classified. (1) By body weight, among infants and toddlers, at each year of age, with increasing the mother's age, there was an increase in percentage of subjects underweight. This tendency of increasing percentage f underweight was more significant in the infant period than the toddler period. (2) By height value, no significant differences between each mother's age group were found. c) When the nutritional status of each child according to the birth rank, i. e. , lower birth rank(first to third) an higher birth rank(fourth of above) was classified. (1) By weight value, children of higher birth rank were slightly more often underweight than those of lower birth rank, but not significant. (2) By height value, no differences were found between children of lower and higher birth rank. 2) Gomez Classification: When the nutritional status of each child was classified a) By body weight value, the percentages for male and female of children, attained standard growth were 53.1%(infant 82.6%, toddler 44.9%) and 39.2%(infant 73.4%, toddler 30.1%), the first degree of malnutrition were 39.4%(infant 14.7%, toddler 46.2%) and 47.1%(infant 21.9%, toddler 53.8%), the second degree of malnutrition were 7.3%(infant 2.3%, toddler 8.6%) and 12.9%(infant 4.0%, toddler 15.2%), and the third degree of malnutrition were 0.2%(infant 0.3%, toddler 0.2%) and 0.8%(infant 0.7%, toddler 0.9%) respectively. b)By body weight value, the percentages for male and female of children, attained standard growth were 80.8%(infant 97.0%, toddler 76.3%) and 73.8%(infant 95.6%, toddler 68.0%), the first degree of malnutrition were 18.5%(infant 2.7%, toddler 22.9%) and 24.6%(infant 4.4%, toddler 30.0%), the second degree of malnutrition were 0.6%(infant 0.3%, toddler 0.7%) and 0.5%(infant 0.1%, toddler 0.7%), and the third degree of malnutrition were 0.1%(infant 0%, toddler 0.1%) and 1.1%(infant 0%, toddler 1.3%) respectively.

PURPOSE: During guided bone regeneration procedures for the augmentation of deficient alveolar ridge, primary closure of flap is necessary. For primary flap closure, flap is repositioned coronally and the zone of attached keratinized mucosa may decreased. The need for attached keratinized mucosa around dental implants is still controversial, but sufficient peri-implant attached keratinized mucosa would be beneficial for functional and esthetic aspects. This case report presents three cases that demonstrated free gingival graft for increasing the zone of peri-implant attached keratinized mucosa which was decreased after guided bone regeneration. MATERIALS AND METHODS: In first case, maxillary incisors were extracted and guided bone regeneration was performed simultaneously. Because the membrane was exposed at 3 weeks after operation, the membrane was removed and free gingival graft was performed for primary flap closure. Free gingival graft was performed again at implant placement for the increase of attached keratinized mucosa. In second case, guided bone regeneration was performed on lower right first molar area, and implant was placed with free gingival graft. In third case, lower right molar area showed insufficient attached keratinized mucosa after implant placement with guided bone regeneration. When abutments were connected, free gingival graft with apically positioned flap was performed. RESULT: In these three cases, the zone of attached keratinized mucosa around dental implants was decreased after guided bone regeneration. And the increase of peri-implant attached keratinized mucosa could be obtained effectively by free gingival graft. CONCLUSION: Free gingival graft could be a effective treatment method increasing the zone of attached keratinized mucosa which was decreased after guided bone regeneration procedures.

BACKGROUND/OBJECTIVES: Chronic alcohol consumption causes oxidative stress in the body, which may accumulate excessively and cause a decline in memory; problem-solving, learning, and exercise abilities; and permanent damage to brain structure and function.Consequently, chronic alcohol consumption can cause alcohol-related diseases.MATERIALS/METHODS: In this study, the protective effects of Phyllostachys edulis (Carrière) J. Houz (PE) against alcohol-induced neuroinflammation and cognitive impairment were evaluated using a mouse model. Alcohol (16%, 5 g/kg/day for 6 weeks) and PE (100, 250, and 500 mg/kg/day for 21 days) were administered intragastrically to mice. RESULTS: PE showed a protective effect against memory deficits and cognitive dysfunction caused by alcohol consumption, confirmed through behavioral tests such as the T-maze, object recognition, and Morris water maze tests. Additionally, PE attenuated oxidative stress by reducing lipid oxidation, nitric oxide, and reactive oxygen species levels in the mice’s brains, livers, and kidneys. Improvement of neurotrophic factors and downregulation of apoptosis-related proteins were confirmed in the brains of mice fed low and medium concentrations of PE. Additionally, expression of antioxidant enzyme-related proteins GPx-1 and SOD-1 was enhanced in the liver of PE-treated mice, related to their inhibitory effect on oxidative stress. CONCLUSION This suggests that PE has both neuroregenerative and antioxidant effects.Collectively, these behavioral and histological results confirmed that PE could improve alcohol-induced cognitive deficits through brain neurotrophic and apoptosis protection and modulation of oxidative stress.

PURPOSE: This study was aimed to evaluate the effect of the Freeze Dried Bone Allograft and Demineralized Bone Matrix on osseous regeneration in the rat calvarial defects. METHODS: Eight mm critical-sized calvarial defects were created in the 80 male Sprague-Dawley rats. The animals were divided into 4 groups of 20 animals each. The defects were treated with Freeze Dried Bone Allograft(SureOss(TM)), Demineralized Bone Matrix(ExFuse(TM)Gel, ExFuse(TM)Putty), or were left untreated for sham-surgery control and were evaluated by histologic and histomorphometric parameters following a 2 and 8 week healing intervals. Statistical analysis was done between each groups and time intervals with ANOVA and paired t-test. RESULTS: Defect closure, New bone area, Augmented area in the SureOss(TM), ExFuse(TM) Gel, ExFuse(TM) Putty groups were significantly greater than in the sham-surgery control group at each healing interval(P<0.05). In the New bone area and Defect closure, there were no significant difference between experimental groups. Augmented area in the ExFuse(TM) Gel, ExFuse(TM) Putty groups were significantly greater than SureOss(TM) group at 2weeks(P<0.05), however there was no significant difference at 8 weeks. CONCLUSIONS: All of SureOss(TM), ExFuse(TM) Gel, ExFuse(TM) Putty groups showed significant new bone formation and augmentation in the calvarial defect model.

BACKGROUND In contrast to defects of the mandible and mouth floor region, in the defect of maxilla, the availability of firmly attached oral and nasal mucosal linings is needed. In addition to it, in consider of operation field, operating convenience, and esthetics, reconstruction using prelaminated flap is strongly recommended. Therefore we consider the prelaminated flap through the cases that is reconstructed using prelaminated forearm flap and prelaminated scapular flap. PATIENTS AND METHODS From 2001 to 2008, in OMFS SNUDH, there were 6 cases that had reconstruction using prelaminated forearm free flap and other 3 cases that had reconstruction using prelaminated scapular flap of maxilla. The average age of patients that were reconstructed using prelaminated forearm free flap was 47.5 years, the average prelaminated period (after 1st operation ~ until 2nd operation) was 51.8 days and the average follow-up period after 2nd operation was 35.3 months. As well, the average age of patients that were reconstructed using prelaminated scapular free flap was 37 years, the average prelaminated period (after 1st operation ~ until 2nd operation) was 57 days and the average follow-up period after 2nd operation was 42.3 months. RESULTS Except 1 case that were reconstructed using prelaminated scapular flap, we could get firmly attached oral and nasal stable skin(mucosal like) lining, more adequate thickness flap than any other flap and improved esthetic and functional results in the other 8 cases that were reconstructed using prelaminated flap. The complications of the prelaminated forearm flap cases were inconvenient swallowing, sputum, limitation of mouth opening and difficult mastication. It came from flap shrinkage of the flap in some aspect, as well as other combined operations such as mass resection or RND. The difficult point of the reconstruction of prelaminated scapular flap was the possibility of vascular damage at preparation of flap in 2nd surgery. The damage could cause the failure of the prelaminated scapular flap. And the skin-lining of the prelaminated flap had limitations, so it is needed to study about the cultured oral epithelium-lining flap instead of the skin-lining flap. CONCLUSION We considered about advantages, complications and notable things of prelaminated flap through maxillary reconstruction cases using prelaminated forearm flap and prelaminated scapular flap so far. Furthermore, we should go on studying for functional reconstruction of prelaminated fasciomucosal flap using cultured oral epithelium.

The edentulous posterior maxilla generally provides a limited amount of bone height because of atrophy of the ridge and pneumatization of the maxillary sinus. Maxillary sinus augmentation is one of the surgical techniques for reconstruction of the severely resorbed posterior maxilla. The purpose of this study was to evaluate the survival rate of implants and the long-term changes of graft height after maxillary sinus augmentation by lateral window approach. From September 1996 to July 2004, maxillary sinus augmentation with mixed grafts of autograft, allograft, xenograft and alloplast were performed on 45 patients and 100 implants were placed. We evaluated the survival rate of implants and the changes of BL(bone length)/IL(implant length) according to time using panoramic radiographs. The survival rate of implants was 91.0% for follow-up period. The mean reduction of graft heights was 0.34mm(3.0%) for 6 months and 1.22mm(10.66%) for 3 years after augmentation. The total mean BL/IL was 1.34+/-0.21 during 5 year observation period after augmentation and decreased slightly over time. The result means that graft materials were stable above the implant apex. BL/ILs of 1 stage procedure were significantly decreased at 1-2 year, 3-4 year after augmentation and no statistically significant changes were observed in those of 2 stage procedure. The graft materials of both procedures were stable above the implant apex. No statistically significant changes of BL/IL were observed in the grafts combined with low amount of autogenous bone or without autogenous bone. The graft materials of both groups were stable above the implant apex. The results indicated that the placement of dental implants with maxillary sinus augmentation showed predictable clinical results and the grafts combined with low amount of autogenous bone or without autogenous bone had long-term resistance to resorption in maxillary sinus.

Food-dependent exercise-induced anaphylaxis (FDEIA) is a specific variant of exercise-induced anaphylaxis that requires both vigorous physical activity and the ingestion of specific foods. In particular, it is rare occurrence for FDEIA to be associated with meat in Korea. A 15-year-old female had generalized urticaria, dyspnea, severe cough, headache, dizziness, and vomiting after singing and dancing for 1 hour and after ingesting grilled pork. Skin prick tests showed a strong positive reaction to pork, whereas the results of an oral food challenge and exercise provocation tests were negative. However, the exercise provocation test after pork ingestion showed a positive reaction manifested by generalized urticaria, cough, mild dyspnea, and a 23% decreased peak expiratory flow rate. Three allergens to pork (67 kDa, 90 kDa, and 15 kDa) reacted with the patient's serum on immunoglobulin E immunoblotting. We report a case of pork-dependent exercise-induced anaphylaxis in a patient who was sensitive to pork.

OBJECTIVE: The purpose of this study was to analyze MTHFR polymorphism among the Korean population and to evaluate the relationship between serum levels of homocysteine and MTHFR polymorphism and also to investigate the effect on pregnancy outcomes. METHODS: DNA was extracted from whole blood of 600 pregnant women. All samples were genotyped for the C677T and A1298C polymorphisms in MTHFR gene by PCR-RELP assay. Serum levels of homocysteine and folate were measured by high performance liquid chromatography for homocysteine and radioassay for folate. Pregnancy outcomes were estimated by gestational weeks and birth weights of newborns. RESULTS: Serum homocysteine was higher in women with the T/T genotype than those with the C/T or C/C genotype of the MTHFR C677T polymorphism (p<0.05). And also serum homocysteine was higher in women with the A/A genotype than those with the A/C or C/C genotype of the MTHFR A1298C polymorphism (p<0.05). Serum homocysteine was negatively correlated with serum folate in all MTHFR genotypes, especially prominent in T/T genotype of MTHFR C677T polymorphism and A/A genotype of MTHFR A1298C polymorphism. Gestational age and the birth weight of infant from hyperhomocysteinemic mothers whose homocysteine levels higher than 15 micromol/L were 36.1 weeks, 3053.8g, respectively, which were significant lower than those from normohomocysteinemic mothers (38.3 weeks, 3,215.3g) (p<0.05). CONCLUSION: Serum homocysteine was influenced significantly by MTHFR C677T polymorphism and MTHFR A1298C polymorphism. MTHFR C677T and A1298C polymorphism and serum homocysteine levels affect pregnancy outcomes, although not mainly by serum folate level.
