The purpose of this study was to investigate the relationship between serum vitamin E levels and the risk of allergic rhinitis among Koreans. This study is a secondary data analysis using big data from the seventh Korea National Health and Nutrition Examination Survey (KNHANES VII-3), which was conducted in 2018. Complex-sample descriptive statistics, t-test, ANOVA and odds ratio were used for data analysis in SPSS 25. The average serum vitamin E level among Koreans aged above 10 was 12.60 mg/L, and 15.9% had been diagnosed with of allergic rhinitis by a doctor. Lower serum vitamin E levels were significantly associated with the prevalence of allergic rhinitis (β=-0.05, p=.013). Therefore, efforts to prevent and manage allergic rhinitis among Koreans should incorporate regular monitoring of vitamin E level and ongoing research into antioxidants.

It is shown that the risk of chronic disease is increased not only by the concentration of fat in the diet but also by the composition of dietary fatty acids. We investigated the anti-oxidant effects of vitamin E on dietary polyunsaturated fatty acid-fed mice. Ninety male Sprague-Dawley rats were randomly divided into 9 groups: a normal diet group (C), 4 dietary polyunsaturated fatty acid diet groups (OA, LA, LNA, DHA), and 4 dietary polyunsaturated fatty acid diet with 0.05% vitamin E groups (OAE, LAE, LNAE, DHAE). The food efficiency in the dietary polyunsaturated fatty acid diet groups was higher than in the normal diet groups. The concentration of malondialdehyde (MDA) was significantly increased by LA and DHA fatty acids. Vitamin E significantly decreased LA and LHA-induced lipid peroxidation. The activity of superoxide dismutase and glutathione peroxidase was increased in the dietary polyunsaturated fatty acid diet groups compared to the control group, while these were decreased by supplements with vitamin E, except in the OAE group. Also, the protein expression of CYP2E1 was significantly increased in only the LNA group, while these were decreased by supplements with vitamin E. These results taken together indicate that vitamin E may have positive effects on a dietary polyunsaturated fatty acid diet-induced oxidative stress in brain tissue.

This study was designed to develop dish recipes using Heatsun sprouts to improve the sprouts' utilization and consumption. We created four kinds of dishes with Heatsun sprouts, including Acanthopanacis cortex, Kalopanax pictus, Aralia elata, and Cedrela sinensis, and analyzed their sensory properties and nutrients. In the sensory evaluation, the overall preference for all the dishes was scored higher than 3.0, Unnaumsun-dakgoginaengchae had the highest score (4.48) among the dishes. Unnamusun-dakgoginaengchae contained higher values of protein; vitamin A, E, and B6; and folic acid than the recommended dietary allowances (RDAs). The recipe for Dureupgokgammuchim was created to reduce the bitterness and the astringent taste of Aralia elata, and it was rich in vitamin C, E, and B6, as well as in folic acid and iron. Ogapisunkkonchijolim was cooked to reduce the fishy smell of a saury with the addition of Acanthopanacis cortex. It contained 1.5 times the protein RDAs, and high levels of antioxidant vitamins, including vitamin A, C, and E. Chamjugmandu was made by the mixing tofu and various vegetables without adding meat. It had the highest calorie count among the dishes, and its vitamin A, C, and E contents were higher than the corresponding RDAs.

비타민(vitamin)이라는 말은 비타민을 처음 발견한 Casimir Funk에 의해서 명명되었는데 생명체에 없어서는 안될 긴요한(vital) 물질이면서 아미노기(-$NH{_2}$)를 함유하고 있는 아민(amine)이라는 뜻으로 vital amine을 줄여서 vitamine이라고 하였다. 그 뒤에 끝의 e가 없어져서 오늘날에는 vitamin이라고 쓰고 있다. Funk가 처음 발견한 비타민은 오늘날 비타민 $B{_1}$이라고도 불리는 티아민(thiamin)이었으며 모든 비타민을 일시에 발견한 것은 아니다. 티아민이 처음 발견된 후에 수십년에 걸쳐서 많은 사람들에 의해서 여러 가지의 다른 비타민이 발견되어서 오늘날에는 14가지 종류의 비타민이 알려지고 있다. 이중에서 처음으로 발견되었던 티아민이 아민이었기 때문에 비타민이라는 말이 명명되었는데 그 뒤에 다른 비타민들의 화학구조가 밝혀짐에 따라 모든 비타민이 다 아민은 아니라는 사실을 알게 되었다. 그럼에도 불구하고 아직까지 비타민이라는 용어는 그대로 사용하고 있는 것이다.

Purpose: The purpose of this study was to determine trends in dietary vitamin E intakes and contributing food groups among Korean adults. Methods: This study included 66,695 subjects aged ${\geq}19years$ who completed a nutrition survey as part of the Korea National Health and Nutrition Examination Survey (1998, 2001, 2005, 2007~2009, 2010~2012, 2013~2015). We estimated individual daily intakes of ${\alpha}-$, ${\beta}-$, ${\gamma}-$, ${\delta}-tocopherol$, and total vitamin E by linking food consumption data with a vitamin E database of commonly consumed foods. Results: Daily vitamin E intake significantly increased from $6.4mg\;{\alpha}-TE/d$ in 1998 to $7.7mg\;{\alpha}-TE/d$ in 2013~2015 (p for trend < 0.0001) among men as well as from $5.4mg\;{\alpha}-TE/d$ in 1998 to $6.5mg\;{\alpha}-TE/d$ in 2013~2015 among women (p for trend < 0.0001). However, the intake of vitamin E was lower than the adequate intake (AI) of Dietary Reference Intakes for Koreans 2015 (2015 KDRI). In 2013~2015, men consumed 6.5 mg/d of ${\alpha}-tocopherol$, 0.5 mg/d of ${\beta}-tocopherol$, 6.0 mg/d of ${\gamma}-tocopherol$, and 3.9 mg/d of ${\delta}-tocopherol$, whereas women consumed 5.7 mg/d of ${\alpha}-tocopherol$, 0.4 mg/d of ${\beta}-tocopherol$, 4.8 mg/d of ${\gamma}-tocopherol$, and 2.8 mg/d of ${\delta}-tocopherol$. The major food groups contributing to vitamin E intake were vegetables (men: 23.3%, women: 22.7%), grains (men: 14.5%, women: 13.9%), and eggs (men: 13.0%, women: 12.5%). Conclusion: This study provides scientific evidence for vitamin E intake in Korean adults. Since the current intake of vitamin E was lower than the reference intakes set by 2015 KDRI, dietary vitamin E intake should be monitored regularly among Korean adults.

Effects of temperature and relative humidity on fat soluble vitamin contents in two commercial vitamin tablets ('Multivitamin Dandelion' and 'vitamin E Yarrow') were investigated. When they stored at different temperature (25, 35, and $45^{\circ}C$) with cap and stored at low relative humidity (11% RH) without cap, all fat soluble vitamins (vitamin A acetate, vitamin E acetate and vitamin E) were stable during 24 weeks of storage period. However, when they stored at high relative humidity (75% RH and 100% RH) without cap, vitamin A acetate and vitamin E acetate dramatically disintegrated at the early stage of storage. On the other hand, vitamin E gradually decreased during storage. Therefore, stability of some fat soluble vitamins, which exist as acetate form, was highly dependent on relative humidity rather than storage temperature. Water may act as a plasticizer and increased the mobility of molecules in vitamin tablet resulting in relatively fast disintegration of some fat soluble vitamins.

The purpose of this study was to investigate the effect of vitamin E on the synthesis of the metallothionein in the liver of streptozotocin (STZ)-induced diabetic rats. Sprague-Dawley male rats($220{\pm}10mg$) were randomly assigned to one control and three STZ-diabetic groups. Diabetic groups were classified to STZ-0E(vitamine E free diet), STZ-40E(40mg vitamin E/kg of diet) and STZ-400E(400mg vitamin E/kg of diet) according to the level of vitamin E supplementation. Blood glucose levels of STZ-diabetic rats were three times higher than that of control. The contents of vitamin E in liver were lower signifciantly STZ-0E, STZ-40E groups by 50%, 36% compared with that of control. Lipid peroxide values(LPO) in liver were higher 5.6 and 2.5 times in STZ-0E and STZ-40E groups than that of control. Plasma cortisol levels were higher STZ-0E and STZ-40E groups compared with those of control, but cortisol levels were lower significantly in STZ-400E group compared with those of the STZ-0E and the STZ-40E groups. The plasma insulin levels were lower in all three STZ-diabetic group compared with that of control, but were not affected by the level of dietary vitamin E. The metallothionein (MT) contents in liver, kidney and small intestine were five times higher in STZ-0E, STZ-40E and STZ-400E compared with that of control, but STZ-400E group was lower in the MT contents in tissues compared with that of STZ-40E group. Zn-MT peak in STZ-diabetic rats liver increased than that of control by Sephadex G-75, and Zn-MT peak divided into MTI and MTII peaks by DEAE Sephadex A-25 column chromatography. The present results indicate that STZ-induced diabetic rats are more sensitive to oxidative stress, leading to the acceleration of lipid peroxidation process, which can be more promoted low level of dietary vitamin E. And the result may that increase synthesis of MT induced in the liver of diabetic rats increased so it can be sure that the diabetes is one of the MT induce factor by free radical generation. And high vitamin E supplementation reduced total MT contents of liver, kidney and small intestine and the peak of purified Zn-MT. Through the results of these experiments, we can conclude that MT might be the free radical scavenger.

This study was performed to investigate the investigated effects of dietary supplementation of vitamin C and E on the growth performance and stress response in broiler chickens. Stress response was analyzed by the quantity of telomeric DNA, the rate of DNA damage and the expression levels of heat shock proteins (HSPs) and hydroxyl-3-methyl-glutaryl coenzyme A reductase (HMGCR) genes on tissues and blood. The telomere length and telomere shortening rates were analyzed by quantitative fluorescence in situ hybridization on the nuclei of lymphocytes and tissues. The DNA damage rate of lymphocytes was quantified by the comet assay. The expression levels of HSP70, HSP90s and HMGCR genes were measured by quantitative real-time polymerase chain reaction in lymphocytes. In results, there was no significant difference among treatments in body weight, weight gain, feed intake and mortality. The telomere shortening rate of the lymphocytes was significantly lower in the vitamin E supplemented group than the control group. The DNA damage was also decreased supplemented with vitamin C and E, as compared to the control group. The vitamin E supplemented group had a significant positive effect on the expressions of HMGCR, HSP90-${\alpha}$ and HSP90-${\beta}$ in lymphocytes, but had no significance on HSP70, as compared to the control group. We concluded that the dietary supplementation of vitamin E (100 mg/kg feed) had reduced the individual physiological stress response without stunt growth in broiler chickens.
