The effect of excess L-ascorbic acid(AsA) in blood, liver lipid levels and peroxidation status were investigate . Ten Sprague-Dawley male rats weighing 150-200g were fed 300mg AsA/100g body weight/day, mixed into ground chow diet, for 4 weeks. And another set of then rats were fed only chow diet as the control. Average body weight gain was slightly lowered by AsA feeding without food intake change. The AsA group showed higher AsA levels in plasma and liver than the control group. In addition, the AsA group showed a higher plasma TBARS value. Liver TBARS seemed to be elevated in the AsA, but not significantly. The hemolysis of red cells tended to increase with excess AsA, accompanied by a raised GSH-Px activity and lowered total GSH levels. Plasma HDL-Chol level was increased while the levels of total Chol, LDL-plus VLDL-Chol , and triglyceride were unchanged . Atherogenic index decreased. Hepatic TG levels were also decreased, but the total amount of Chol increased slightly . Platelet TXA$_2$ production was inhibited by excess AsA feeding. Above results indicafe that oral feeding of excess AsA may be beneficial in reducing the risk of atherosclerosis ; however such practice may be detrimental for tissue lipid peroxidation and weight gain.

The present study was carried out to investigate the antidiabetic and antioxidant effect of methanolic extract of Berberis tinctoria leaves (MEBT), in streptozotocin induced diabetic rats. Oral administration of MEBT extract (150 mg/kg and 300 mg/kg) for a period of 14 days. Blood glucose levels, body weight food and liquid intake were measured on every $5^{th}$ day over a period of 14 days. In diabetic rats, MEBT at the dose of 150 mg/kg and 300 mg/kg body weight resulted in significant reduction in blood glucose levels. The study was further investigated to determine antioxidant and antihyperlipidemic potential of MEBT in streptozotocin (STZ) induced diabetic rats. These results suggest that the MEBT possess antidiabetic activity and is able to ameliorate biochemical damages in STZ induced diabetic rats and the results were found to be in a dose dependent manner.

흡연은 전신건강 뿐 아니라 구강건강에도 유해하여 구강암과 치주염의 발생, 창상치유 지연, 치아상실 등과 관련성을 가지는 것으로 알려져 있다. 이미 흡연과 구강건강의 관련성에 대한 연구가 많이 있지만, 구강건강에 대한 인식도나 위생관리 등 흡연 외의 다양한 요소가 구강건강에 영향을 줄 수 있으며 타액 분비나 구취처럼 흡연과의 관련성이 확실히 밝혀지지 않은 부분도 존재한다. 그러므로 구강위생에 대한 인식 수준이 상대적으로 높고 추적조사가 용이한 치과대학생이라는 집단에서 흡연자와 비흡연자의 구강건강을 상태를 장기적, 포괄적으로 비교한다면 흡연이 구강건강에 미치는 영향을 보다 명확하게 확인할 수 있을 것이다. 본 연구는 장기적 연구에 앞서 치과대학생 중 흡연자들의 흡연 특성을 파악하고, 흡연자들과 비흡연자들의 전반적인 구강건강상태를 비교하여 보고하고자 하였다. 2010년 4월 21일부터 2011년 4월 20일까지 단국대학교 치과대학 치의학과에 재학 중인 1학년부터 4학년까지의 남학생 224명 중 지원자 192명(85.7%)을 대상으로 하여 설문지 조사와 임상검사를 시행하였다. 설문지조사에는 흡연 양태, 음주, 니코틴의존도, 구강위생관리, 간이심리검사가 포함되었고 임상검사에는 치아 및 치주 상태, 니코틴 착색, 타액분비량, 전기 미각역치, 구취에 대한 평가가 시행되었다. 본 연구에서, 흡연자군은 금연자군, 비흡연자군에 비해 연령이 약간 높고, 음주를 하는 경우가 많았으며 알코올섭취량도 많았다(p<0.05). 세 군은 타액분비율, 구취, 전기미각역치 등의 임상조사에서는 유의한 차이를 보이지 않았으나, 양치질 횟수나 치과방문 횟수에 차이가 없음에도 불구하고 우식경험영구치율(DMFT rate), 치주가료필요 정도 및 니코틴 착색 정도에 있어서 흡연자군과 비흡연자군 사이에는 차이가 관찰되었다(p<0.05). 본 연구의 피검자들이 평균 25세로서 흡연자군이라 해도 흡연기간이 길지 않고 흡연량이나 니코틴의존도가 낮은 수준임에도 불구하고 치주조직에는 이미 유해한 효과를 주고 있다고 판단된다. 기초 자료 분석이지만 흡연은 치주조직에 신속히 영향을 미치므로 금연 치료를 조기에 시행할 필요가 있다.

Zinc deficiency is known to be associated with insulin resistance in obese individuals. This study was performed to evaluate the effect of zinc supplementation on insulin resistance and metabolic risk factors in obese Korean women. Forty obese women (body mass index (BMI) ${\geq}25kg/m^2$) aged 19-28 years were recruited for this study. Twenty women of the study group took 30 mg/day of supplemental zinc as zinc gluconate for 8 weeks and 20 women of control group took placebo. Usual dietary zinc intake was estimated from 3-day diet records. Insulin resistances were measured using Homeostasis model assessment (HOMA) indices, and insulin sensitivities Matsuda indices, which were calculated using oral glucose tolerance test data. Metabolic risk factors, such as waist circumference, blood pressure, fasting glucose, triglyceride, high density lipoprotein (HDL) cholesterol, and adipocyte hormones such as leptin, and adiponectin were also measured. At the beginning of study, dietary zinc averaged 7.31 mg/day and serum zinc averaged $12.98{\mu}mol/L$ in the study group. Zinc supplementation increased serum zinc by 15% and urinary zinc by 56% (P < 0.05). HOMA values tended to decrease and insulin sensitivity increased slightly in the study group, but not significantly so. BMI, waist circumference, blood pressure, blood glucose, triglyceride, HDL cholesterol, and adipocyte hormones did not change in either the study or control group. These results suggest that zinc status may not affect insulin resistance and metabolic risk factors in obese Korean women. Further research is required on a larger cohort with a longer follow-up to determine the effects of zinc status on insulin resistance and metabolic variables.

It is important to supply adequate nutrition to critically ill patients, whose gastrointestinal system is properly functioning, through the enteral tube feeding if oral intake is impossible. In this study we investigated the changes in nutritional status with enteral tube feeding according to the volume required. We investigated the volume ordered according to the patient's requirements, volume infused according to the volume ordered in 41 enteral tube feeding patients in intensive care unit from Jannuary to July, 2000. Body weight, serum albumin level, and total lymphocyte count were evaluated to assess nutritional status. The mean fasting period was 5 days before the enteral feeding and patients whose fasting period over 3 days were 51%. The mean enteral tube feeding period was 29 days and method of feeding was nasogastric, bolus feeding 6 times per day. The volume ordered was 69.7% of the patients' recommended calorie and volume infused was 86.6% of their volume prescribed. Accordingly, the volume infused was estimated 61.7% of their volume required. Only 44.6% of their reqiured volume was infused within 3 days after enteral tube feeding was started. It took 16 days in average to meet the patients' recommended calorie; 56% of subjects still did not fully met their requirements by the end point. Among the impeding factors in supplying enteral tube feeding, factors related to the number of feeding were high residual volume in stomach, vomiting, gastrointestinal bleeding, abdominal distension and surgery. Factors related to the acctual infused volume were diarrhea, gastrointestinal bleeding, abdominal distension, airway management and tube reinsertion. Significant correlations were shown between the volume infused and changes in both the patients' weight and serum albumin level. Deviding the subjects into two groups by their infused volume, less than 70% and more than that, we compared the two to come up with a significant difference in their serum albumin level, -0.23 vs 0.21, and their body weight, -4.52 vs 0.12. In enteral tube feeding, the volume delivered in sufficient to the pateints' energy requirement can affect their nutriitional status in critically ill patient; adequate nutritional management plan is essential. It is necessary to make every effort to educate clinical staff and to set up a unified management program to prescribe adequate ammount of energy for the patient's nutritional requirement.

The prevalence of iron deficiency in later infancy and the toddler years(25% to 40% at 1 year of age) has not decreased remarkably , except in Western countries. The purpose of this study was to 1) determine the relationship between current feeding practices and iron status, and 2) assess compliance to infant feeding instructions. Two groupsof infants were examined. The first group of 302 infants aged 6 to 24months was seen at a well baby clinic while the second group of 135 infants of the same age group was assessed by venipuncture. Cutoff values for laboratory tests were as follows ; hemoglobin<11g/dL, mean corpuscular volume (MCV) <72fl ; red cell distribution width(RDW)>15% ; serum ferritin level<10ng/ml ; and transferrin saturation (serum iron(TIBC)<10%. The diagnosis of iron deficiency anemia (IDA) was made when a low hemoglobin level was associated with either low ferritin orlow transferrin saturation . Of the 302 children brought to the well baby clinic , 12.3%(n=37) were found to have anemia (hemoglobin<11.0/dL). In terms of children grouped according to feeding practices, it was found that children with anemial comprised 32.0% (24/75) of the prolonged breast-fed group (Group A), significantly more than the 4.0%(7/176) of the artificial milk feeding group(Group B). and 3.9%(2/51) of the switched from breast milk to iron -fortified weaning foods group(Group C).Among the 107 children with IDA , iron deficiency in 105 children(98.1%) was suggested by their dietary histories ; exclusive or prolonged breast-feeding for more than 6 months without iron fortification in 98 infants ; cow's milk consumption> 500ml/day without iron fortification during infancy(n=12), or >800ml without iron-fortified foods after infancy(n=15) ; and the use of unfortified forumula or unbalanced diets, mainly limited to rice gruel. Despite the relatively high (79.6%) motivation on the part of the infants mothers and supervison by professional personnel, the poor results in the infants receiving iron fortified foods were due to poor compliance(85.75). Among the mothers of 98 IDA patients who were contacted by telephone , it was revealed that 29% did not give the oral iron preparation for more than 2 months. Furthermore, negligence or disregard by the parents occurred in 14% of the case , discontinuance of the oral iron preparation by the parents due to side effects occurred in 6%, and the children's refusal or poor oral intake and no further trial occurred in 6%. The dietary history of a large group of infants was highly predictive of their risk for anemia . Continued consumption of breast milk until the age of 1 year is not warranted unless iron-fortified foods are given concomitantly. Because there is a problem with compliance, more successful and safe strategies for preventing iron deficiency woold included dual coverage in the from of therapeutic iron supplementation as well use of iron-fortified foods for teddlers who are at risk of iron deficiency.

우리나라 젊은 여성의 리보플라빈 영양상태를 평가하기 위하여 광주시에 거주하는 젊은 여성 8명을 대상으로 3주간의 식이섭취조사와 임상검사를 실시하고 EGRAC를 측정하여 다음과 같은 결과를 얻었다. 본 실험 대상자의 평균연령은 22.1세였으며 신장은 154.4cm, 체중은 49.2kg, 흉위는 81.2cm, 상완 하부, 견갑골 하부 및 복부 피부두께의 합은 79.5mm, BMI는 20.6이었다. Hb함량은 13.0g/100ml, Hct 치는 44.0%, A/G ration는 1.4, GOT, GPT 및 alkaline phosphatase활성은 각각 14, 11.0 및 6.5로서 혈액학적 및 임상적으로 이상이 없었다. 에너지, 단백질 및 리보플라빈의 1일 평균 섭취량은 각각 1745kcal, 56.1g 및 1.14mg으로 한국인 영양 권장량에 비해 낮았다. 리보플라빈의 주요 급원 식품은 우유로서 27.7%의 리보플라빈의 주요 급원 식품은 우유로서 27.7%의 리보플라빈이 우유로부터 공급되었고, 기타 달걀, 배추, 쌀, 쇠고기 등의 순으로 기여도가 높았다. ERGAC는 평균 1.2784이었으며 ERGAC는 1.20이상으로 생화학적인 리보플라빈 결핍상태인 대상자는 62.5%이었다. 이들에게 1일 6mg의 리보플라빈을 1주간 투여한 결과 ERGAC는 모두 1.20이하로 감소되었다. 에너지, 단백질 리보플라빈 섭취량은 상호간에 고도의 유의적인 정상관을 보였고, 이들은 모두 EGRAC와 유의적인 부적상관을 보였다. 그러나 에너지 섭취량 1,000kcal를 단위로 나타낸 리보플라빈 섭취량은 에너지 섭취량과는 유의적인 부적상관을 보인 반면 단백질 섭취량과는 상관을 보이지 않았고 EGRAC와도 유의적인 상관을 보이지 않았다. 본 연구결과는 한국인 은 여성의 리보프랄빈 영양상태를 생화학적 방법으로 평가한 결과 상당수가 결핍상태에 있음을 보여주었다. 또한 리보플라빈 섭취량은 에너지 및 단백질 섭취량과 고도의 유의적인 정상관을 가지므로 리보플라빈 섭취량을 늘리기 위해서는 에너지 또는 단백질섭취량을 증가시켜야 한다는 점이 시사되었다. 한편 에너지 섭취가 낮은 경우에 리보플라빈 섭취량에 특히 유의해야 한다는 점도 시사되었다. 시사되었다.
