We studied the nutritional status of on mentally handicapped children living at home or in institutions since early teenage years are nutritionally important. The subjects of 7 to 12 year old mentally retarded children attenending a special education school in Seoul were surveyed with questionnaires as well as 2-day dietary recall records, with the help of persons of their care-giver when needed. Among the 64 children,54.7% are living in institutions and the rest of them are living at home. They were ranged from the trainable (64.1%) , the educable (26.6%) , and the non-trainable (9.4%) . Their average daily intake of energy intakes (%RDA) was 2,070.1 kcal (94.1%) , Ca 603.9 mg (75.5%) , Fe 11.1 mg (92.5%), Vt.A 507.5 RE (84.6%) , Vt. B$_2$.1g (88.2%), niacin 14.1 g (93.6%) and Vt. C 58.2 g (83.1%) . Their average intakes of these nutrients were significantly higher in subjects of institutions than at home. The nutrients consumed at a much higher level than the RDh of the normal children were Vt. B, (1.6 g,146.8%) and protein (75.3g, 136.9%) . The higher percentage of children at home were under consumed of several nutrients (< 75% RDA) than ones in institutions. When comparing the degree of handicap, energy and nutrient intakes except Vt. C were highest in educable children than trainable ones or Dawn's children. MAR of the diets of the subjects was 0.84. Children at home showed lower MAR as well as NAR of each nutrients, whereas children belonged to INQ < 1 were less at home. Handicapped children at home were snacking higher amount relative to their calorie intake and too frequently, that may lead to their poor nutrition. There was positive correlations between factors of nutrition and physical and dietary behaviors, but there were no correlations between factors of nutrition and health-related habits. Nutritional caring mentally handicapped children in institutions seemed to be more effectively managed.
Although iron is an essential mineral, excess iron intake during pregnancy may increase oxidative stress in tissues. This study was conducted to investigate the effects of iron overload during pregnancy on iron status and oxidative stress in maternal rats. Ten week-old female Sprague-Dawley rats were mated with male rats. Non-pregnant (control) and pregnant rats were fed diets containing normal Fe (35 mg/kg diet), high Fe (350 mg/kg diet), or excess Fe (1,050 mg/kg diet) during pregnancy. Rats were sacrificed on pregnancy day 19. No significant difference in weight gain, diet intake, or litter size was observed according to iron intake levels. Furthermore, serum iron, hemoglobin, and hematocrit were not different among the rats administered the three levels of Fe both in the control and pregnant groups. However, the iron levels were lower in pregnant rats than those in the control. The liver and spleen iron contents increased significantly in the excess Fe group. An increase in liver ferritin levels with increasing iron intake was observed. Protein carbonyl content, as a marker of oxidative stress, increased significantly in liver with increasing iron intake but not malondialdehyde. Glutathione peroxidase activity in the liver of pregnant rats fed excess iron decreased significantly. Bcl-2 protein expression in the liver declined remarkably with increasing maternal iron intake in pregnant rats. Taken together, iron overload during pregnancy had little effect on hematology. However, the deposits of iron in the liver and the decline in antioxidant enzyme activity implied increased oxidative stress in tissues of the excess Fe group. These results suggest that excess iron intake during pregnancy increases oxidative stress in maternal tissues and may also affect fetal tissues.
Ultraviolet (UV) irradiation reduces epidermal hydration, which is paralleled by the reduction of natural moisturizing factors (NMFs). Of various NMFs, free amino acids (AAs) are major constituents generated by filaggrin degradation. In this study, we attempted to determine whether dietary supplementation of royal jelly (RJ) in UV-irradiated mice can alters epidermal levels of hydration, filaggrins, and free AAs as well as of peptidylarginine deiminase-3 (PAD3), an enzyme involved in filaggrin degradation processes. Albino hairless mice were fed either a control diet (group UV+: UV irradiated control) or diets with 1% RJ harvested from different areas in Korea (groups RJ1, RJ2, and RJ3) or imported from China (group RJ4) for six weeks in parallel with UV irradiation. A normal control group (group UV-) was fed a control diet without UV irradiation for six weeks. Reduced epidermal levels of hydration, total filaggrins, and PAD3 were observed in group UV+; in group RJ1, these levels were increased to a level similar to that of group UV-. In addition, profilaggrins, two repeat intermediates (2RI), a precursor with two filaggrin repeats, and filaggrin were increased. Although no alteration of AAs was observed in any of the groups, and glutamate and serine, major AAs of NMF in group RJ1 were higher than in group UV+. Despite the increased levels of PAD3, epidermal levels of hydration, filaggrins, glutamate, and serine in groups RJ2, RJ3, and RJ4 were similar to those in group UV+. Dietary supplementation of RJ1 improves epidermal hydration in parallel with enhanced expression and degradation of filaggrin, but not by increased protein expression of PAD3, along with increased generation of glutamate and serine.
Dietary supplement use is prevalent and represents an important source of nutrition. This study was conducted in order to assess the dietary maximum exposure of vitamins and minerals from various sources including regular diet, vitamin mineral supplements for non-prescription drug (VMS-NPD), vitamin mineral supplements for health functional foods (VMS-HFF), and fortified foods (FF). A total of 1,407 adolescent boys and girls attending middle or high schools were chosen from various cities and rural communities in Korea. Users of vitamin and mineral supplements (n = 60, 15-18 years of age) were chosen from the above 1,407 students. Intake of vitamins and minerals from a regular diet and FF was assessed by both food record method and direct interview for three days of two weekdays and one weekend, and those from VMS-NPD and VMS-HFF were assessed by both questionnaire and direct interview, and compared with the recommended nutrient intake (RNI) and the tolerable upper intake level (UL) for Korean adolescents. Daily average exposure range of vitamins and minerals from a regular diet was 0.3 to 4.4 times of the RNI. Some subjects had an excessive exposure to the UL in the following areas: from regular diets, vitamin A (1.7%) and niacin (5.0%); from only VMS-NPD, vitamin C (9.1%) and iron (5.6%); and from only VMS-HFF, niacin (8.6%) > vitamin $B_6$ (7.5%) > folic acid (2.9%) > vitamin C (2.3%). Nutrients of daily total intake from regular diet, VMS-NPD, VMS-HFF, and FF higher than the UL included nicotinic acid for 33.3% of subjects, and, then, in order, vitamin C (26.6%) > vitamin A (13.3%), iron (13.3%) > zinc (11.7%) > calcium (5.0%) > vitamin E (1.7%), vitamin $B_6$ (1.7%). Thus, findings of this study showed that subjects may potentially be at risk due to overuse of supplements, even though most of them took enough vitamins and minerals from their regular diet. Therefore, we should encourage adolescents to have sound health care habits through systematic and educational aspects.

This study was conducted to examine the changes in serum lipid components and blood glucose by krill (Euphausia superba) meal and sodium fluoride (NaF) in rats fed on experimental diets and administered orally to NaF 10 mg for 5 weeks. Body weight of rats decreased as the amount of krill meal diet increased, it was observed the basal diet plus NaF group (BF group) compared to the lower basal diet group (BD group). The serum concentrations of total cholesterol, LDL (low-density lipoprotein) cholesterol, free cholesterol, triglyceride (TG), phospholipid (PL) and blood glucose in serum were higher in the BF group than the 10% krill meal group plus NaF 10 mg (KF10 group) or BD group, the 20% krill meal plus NaF 10 mg group (KF20 group), the 30% krill meal plus NaF 10 mg group (KF30 group). Conversely depending on the content of krill meal for the HDL (high-density lipoprotein) cholesterol level, it showed higher results. The concentration of total protein was no significant difference among the groups (p<0.05). The results indicate that a krill meal diet effectively inhibited increases in lipid elevation and blood glucose level in the sera of rats.

This study was designed to examine the effects of n-6 PUFA rich corn oil, n-3 PUFA rich perilla oil and their conjugated double bond derivatives on serum lipids status in rats. Experimental diets containing lard (control), corn oil (CO), perilla oil (PO), conjugated double bond derivatives of n-6 PUFA rich corn oil (TCO) and n-3 PUFA rich perilla oil (TPO) at the level of 10% (w/w) were fed to male Sprague Dawley rats for 4 weeks. TCO was found to have three derivatives of linoleic acid and TPO had five derivatives of linolenic acid by GC. Serum total cholesterol levels were significantly lower in the all experimental groups than in the control group, and particularly, the lowest in TCO and TPO groups. HDL-cholesterol concentrations were a little higher in the all experimental groups than in the control group, and TCO and TPO groups were not significantly different from CO and PO groups. Serum LDL, LDL-cholesterol, chylomicron and triglyceride concentrations were significantly lower in the all experimental groups than in the control group, remarkably lower in TCO group and particularly, the lowest in the TPO group. Serum free cholesterol and cholesteryl ester concentrations were lower in TCO and TPO groups than in CO and PO groups. From the above research, TCO and TPO groups were effective on the improvement of the lipid compositions in serum and particularly, TPO group was the most effective on the improvement of serum lipids.
This study was conducted to investigate the economic analysis of fermented diet made of agricultural and marine by-products such as, dropped apples, persimmon shells, mushroom (Flammulina velutipes) by-products, king oyster mushroom by-products and brewer's grain in Berkshire or crossed pigs. The daily diet cost were decreased by 2.16~3.44%, 3.83~13.35% and 7.47~41.61% when fermented dropped apples diet, fermented persimmon shells diet and fermented mushroom (F. velutipes) by-products diet were fed to Berkshire pigs. The daily feed cost was also decreased by 1.59~4.05% and 59.09~66.90% when fermented king oyster mushroom by-products diet and fermented brewer's grain diet were fed to crossed pigs. Carcass prices were increased by 3.09%, 1.20~3.40% and 1.13% when 2% fermented dropped apples diet, fermented persimmon shells diet and 0.5~1.0% fermented mushroom (F. velutipes) by-products diet were fed to Berkshire pigs. Carcass prices were increased by 2.87~4.19% and 41.31~49.14% when fermented king oyster mushroom by-products diet and fermented brewer's grain were fed to crossed pigs. Therefore, fermented agro by-products diet of dropped apples, persimmon shells, king oyster mushroom, mushroom (F. velutipes) and brewer's grain was expected to improve swine farms income due to decreased diet cost and increased carcass prices in Berkshire pigs or crossed pigs.
Purpose: West syndrome is a severe form of age-specific epilepsy that typically affects infants younger than 2 years of age with mitochondrial disease. We aimed to examine age-specific characteristics of the syndrome in these patients. Methods: We retrospectively analyzed 54 patients with West syndrome diagnosed with mitochondrial disease between March 2006 and March 2016. We compared treatment strategies and diagnostic and clinical variables between patients with early-onset (<6 months of age) and late-onset (${\geq}6$ months of age) seizures. Results: Seizure was the first symptom in 30 (90.9%) and 13 (65%) patients of the early-onset and late-onset groups, respectively (P=0.046). Delayed development was observed in 3 (9.1%) and 7 (35%) patients of the early-onset and late-onset groups, respectively (P=0.023). Lactate levels were normal in 17 patients (55%) of the early-onset group and 5 (25%) of the late-onset group (P=0.036), while initial brain magnetic resonance imaging (MRI) findings were normal in 23 (67.6%) and 8 (40%) patients of the early-onset and late-onset groups, respectively. Final MRI findings were abnormal in 32 patients (94.1%) of the early-onset group and 18 (90%) of the late-onset group (P=0.036). Although ketogenic diets reduced seizure frequency in both groups, the difference was not significant. Conclusion: There is no significant difference in epilepsy-related variables when patients are divided based on a cut-off age of 6 months. However, differences in the first symptom at onset and MRI findings were observed. Although lactate levels were not of significant diagnostic value in the early-onset group, they may be in the late-onset group.
This study was designed to develope the functional anti-diabetes drink, Dia-D using silkworm (Bombyx mori L) extract Sprague-Dawley (SD) male rats (160${\pm}$10g) were fed basic diet (control group), and experimental diets (SWE-l0, 30, 60 groups and Daonil-40, 80 groups) added silkworm extract 10, 30 and 60mg/day or diabetes drug prepared and marketed by Handok Pham. Co., Daonil 40 and 80 mg/day for 12 days. Blood glucose contents were significantly decreased 25-30% in SWE-30 and SWE-60 groups, and about 35% in Daonil 40 and Daonil 80 groups compared with control group. Triglyceride (TG) and lipid peroxide (LPO) contents were significantly inhibited 10-16% and 8-13%, respectively, in SWE-30 and 60 groups, whereas these contents were 13-30% and 15%, respectively, in Daonil-40 and 80 groups compared with control group. Hydroxyl radical (OH) contents were significantly inhibited 19-20% in SWE-30 and 60 groups, and 7-12% in Daonil-40 and 80 groups compared with control group. Superoxide dismutase (SOD) activities were significantly increased 11-14% in SWE-30 and 60 groups, and 12-29% in Daonil-40 and 80 groups compared with control group. In results of clinical test using normal subjects, blood glucose content tested in NIAST subjects as anti-diabetes drink, Dia-D willi 100mg/vial was significantly decreased 17.5%, and these content tested in PKNU subjects as anti-diabetes drink, Dia-D with 150mg/vial was significantly decreased 20.5% compared with control group. These results suggest that administration of Dia-D as an anti-diabetes drink prepared with silkworm extract may playa very effective role in a decreasing of blood glucose in hyperglycemia patients.

The object of this study was to evaluate the effects of dietary supplementation of mulberry leaves and silkworm excreta ethanol extracts on weight performances, blood characteristics, cecal microflorae of chickens. Two hundred forty male broiler chicks(Ross) were fed diets for five weeks containing 0.1%(MLA) and 1%(MLB) of mulberry leaves ethanol extracts, and 0.1%(SEA) and 1%(SEB) of silkworm excreta ethanol extracts. Weight performance did show no significant difference in all test groups which were fed with supplementation of mulberry leaves and silkworm excreta ethanol extracts. They showed better weight gain and feed conversion than the negative control group which was fed only with forage without antibiotics. ABTS(2'-azine-bis[3-ethylbenzothiazoline-6-sulfonic acid]) test was conducted to investigate free radical scavenging activity of blood in tested groups. ABTS scavenging activities of tested groups were higher than control groups in significant level, though there was no significant difference(P = 0.396). Specifically, MLB group showed the highest scavenging activity. Blood-level concentration of MDA, which is an indicator of lipid peroxidation, was also decreased in tested groups and the lowest level was observed in SEA(P = 0.001). As storage time increased at $4^{\circ}C$, muscle-level MDA concentrations of all tested groups were generally increased and significant difference was obsereved between tested groups and controls in total increase of MDA concentration($P=4.417{\times}10^{-3}$). In cecal microflorae, SEA and SEB showed decreased total microbe population compared to NC($P=6.462{\times}10^{-5}$) and even to PC. Supplementation of mulberry leave and silkworm excreta ethanol extract did show a similar inhibition effect against Salmonella sp., furthermore, MLB did enhanced the growth of Lactobacillus sp.($P=3.636{\times}10^{-7}$). In summary, ethanol extract of silkworm excreta may be a potential alternative of antibiotics for chicks. In addition, both of ethanol extracts supplementation to broiler chicks would be very useful not only to improve antioxidant effect of blood but also to suppress lipid peroxidation without any loss of weight performance in poultry farming.
