The purpose of this study was to investigate the effect of vitamin B6 deficiency on the concentration of energy metabolite in streptozotocin-induced diabetic rats. Thirty rats were fed a vitamin B6 deficient diet(-B6) or a control diet(+B6) for 5 weeks and then subdivided into 3 groups respectively ; base group, one day diabetic group and three day diabetic group. Diabetes of rats were induced by streptozotocin injection into the tail vein. Glucose, glycogen, protein, alanine, triglyceride and free fatty acids were compared in plasma, liver skeletal muscle of rats. Also, the total urinary nitrogen and glucose excretion were compared. Compared with +B6 rats, the increase of plasma glucose in -B6 rats due to the diabetes was smaller. After diabetes was induced, the level of plasma alamine was not changed in -B6 rats while increased significantly(p<0.05) in +B6 rats. The increase of urinary nitrogen excretion was smaller and the increase of muscle protein was larger in -B6 rats at the first day diabetes was induced. The levels of plasma free fatty acid and liver triglyceride were significantly (p<0.05) higher in -B6 rats after diabetes was induced. These results suggest that vitamin B6 deficiency may impair the adaptation of animals to the energy metabolism related due to a decrease of the body protein catabolism of fatty acid oxidation in diabetes and aggravate fatty liver which is one of the chronic complications of diabetes.
Purpose : Hypocalcemia is one of the major causes of convulsion in infants. The causes of hypocalcemia are hypoparathyroidism, deficiency and metabolic abnormalities of vitamin D, or increased uptake of inorganic phosphorous, etc. We analyzed the causes, symptoms and signs, treatment, and clinical courses of hypocalcemia as, recently, there were many clinical experiences of hypocalcemic infants under age of 6 months in the department of pediatrics, Kyungpook University Hospital. Objects and Methods : The authors observed 11 infants with hypocalcemia who had been admitted to the department of pediatrics, Kyungpook University Hospital, during the period of February 1992 to April 1997. Various clinical and laboratory data concerning causes, clinical courses and treatment of hypocalcemia were analyzed retrospectively Results : (1) The sex incidence revealed male predominance with male to female ratio 4.5 : 1. The mean age at onset of symptoms was $2.2{\pm}1.1$ months old. (2) The causes of hypocalcemia were vitamin D deficiency in 8 cases and excessive inorganic phosphate intake in 3 cases. (3) All eleven patients manifestated convulsion which was generalized tonic-clonic in 9, and focal clonic in 2 cases. (4) Serum calcium concentrarion increased from $6.3{\pm}0.9$ mg/dL to $9.9{\pm}1.7$ mg/dL after therapy of $1,25(OH)_{2}D_{3}$ with or without calcium(P=0.0008), and serum ALP concentration decreased from $1,418{\pm}864$ U/L to $772{\pm}503$ U/L (P=0.0112). Serum iPTH levels were high in all 11 patients initially. All showed decreased $25(OH)D_3$ levels initially. (5) All patients were treated successfully with $1,25(OH)_{2}D_{3}$ and/or calcium supplement. Conclusions : Vitamin D deficiency should be considered as one of the causes of hypocalcemia even in formula(known as vitamin fortified) feeding infants. Fortunately, they were successfully treated with $1,25(OH)_{2}D_{3}$.

Menopause is often associated with several chronic diseases, including osteoporosis, cardiovascular disease, and obesity. In this study, we investigated the ability of Eisenia bicyclis (EB) to prevent bone loss in ovariectomized rats, a model for postmenopausal osteoporosis. Extracts from EB obtained using ethanol or hot water were analyzed for total polyphenol content and osteoporosis effects in vivo. Total polyphenol content was higher with extraction by hot water compared to ethanol extraction. Fifty 8-week-old female Sprague-Dawley rats were randomly assigned to four groups: the group were sham-operated rats (SHAM), ovariectomized rats (OVX-CON), and ovariectomized rats that were treated with EB at 50 mg/kg body weight (OVX-EB50) and 200 mg/kg body weight (OVX-EB200), respectively. The diets were fed to rats for 6 weeks after their operation. We found that the alkaline phosphatase (ALP) activity was lower in the EB extract group compared to the OVX-CON group. Collagen and pyridinoline content, in bone and cartilage, were reduced by ovariectomy, but the supplemented EB extract groups exhibited higher concentrations in their bones. These results suggest that EB can be used for the industrial development of foods with therapeutic functions.

This study was Conducted to investigate the effect of ${\gamma}-PGA\;({\gamma}-poly\;glutamic\;acid)$ on Ca absorption and bone metabolism in rats. Weaned 4-week old male rats were fed Ca-deficient diets for 3 weeks after the adjustment period. Rats were divided into 6 groups and were fed experimental diets for four weeks. Experimental groups were basal (Ca deficient), control (Ca diet: Ca 0.45%), CP1(Ca 0.45%+casein phosphopeptide 1%), PG1(Ca 0.45%+gamma poly glutamic acid 1%), CPG (Ca 0.45%+casein phosphopeptide 1%+gamma poly glutamic acid 1%) and PG3(Ca 0.45%+gamma poly glutamic acid 3%). Though daily Ca intake and food intake of experimental groups showed no significant difference that of control group. The values of fecal Ca excretion and urinary Ca excretion in groups fed ${\gamma}-PGA$ were significantly lower than that in tile control group. The values of Ca absorption in groups fed ${\gamma}-PGA$ were significantly higher than that in the control group. The levels of femur Ca in ${\gamma}-PGA$ supplemented group were significantly increased compared to the control group. Also, breaking force of femur in ${\gamma}-PGA$ supplemented group showed about 40% increase compared to the control group. These results show that ${\gamma}-PGA$ supplement could be helpful to increase Ca absorption as well as to intensify the femur strength and to increase the Ca content of femur in rats.
This study was designed to investigate the characterization of black goat meat and bone beverage containing honey of red ginseng. The crude proteins and moisture contents of black goat meat were higher than those of pork and beef, but the crude lipid content of black goat meat was lower than that of those. The potassium content of black goat meat was lower than that of chicken, but similar to the pork and beef. The sodium content of black goat meat was lower than that of chicken, pork and beef. The result of the sensory evaluation of black goat meat and bone beverage added honey with red ginseng by 25 panels, was that the beverages added $7.5\%\;and\;8.0\%$ honey with red ginseng were better than any other beverages. Thus, the results suggest that the black goat meat bone beverage added honey with red ginseng could be one of valuable drinks.

Purpose: Malnutrition is a common postoperative complication that occurs after gastric resection. Several causes for malnutrition have been proposed, which include malabsorption and poor oral calorie intake. We performed this study to evaluate whether nutritional counseling would increase oral calorie intake and improve nutritional status in patients who had undergone gastrectomy. Materials and Methods: Twenty-two patients were randomly selected as the study group from among patients who had undergone gastrectomy for early gastric cancer and gastric polyp between October 1999 and December 2000. Body weight, hemoglobin, serum albumin, and serum transferrin were checked before and after the gastrectomy. Oral calorie intake was evaluated by using a 3-day oral-intake diary, and one nutritionist performed outpatient-based nutritional counseling. Eighteen patients who had undergone gastrectomy for the same disease during the same period were selected as the control group. Results: During an average interval of 14.8 months, the study patients received nutritional counseling an average of 3.4 times at an average interval of 4.4 months. The study group took a mean of $2055.6\pm418.1$ Cal per day and the control group $1792.1\pm421.9$ Cal (P=0.05). Sixty-eight percent (15 patients) of the study group patients reached the daily-required calorie intake. Postoperative bodyweights were $64.0\pm9.9$ kg for the study group and $64.3\pm10.8$ kg for the control group (P>0.05). No statistically significant differences were observed among the other. Sixty-five percent of the patients (26 patients) had a weight loss of less than $10\%$ of the preoperative body weight, and $35\%$ had more than a $10\%$ weight loss, but there was no statistical difference between the calorie intakes of these patients. Conclusions: Nutritional counselling increased the oral calorie intake, but nutritional status was not improved. These results suggest that nutritional derangement after gastrectomy cannot be corrected by adequate oral intake itself.

X-linked adrenoleukodystrophy (ALD) is a rare inherited metabolic disease which results in impaired peroxisomal ${\beta}$-oxidation and the accumulation of very long chain fatty acids (VLCFA) in the adrenal cortex, the myelin of the central nervous system, and the testes. X-linked ALD is caused by mutations in the ABCD1 gene encoding an ATP-binding cassette transporter superfamily located in the peroxisomal membrane. This disease is characterized by a variety of phenotypes. The classic childhood cerebral ALD is a rapidly progressive demyelinating condition affecting the cerebral white matter before the age of 10 years in boys. We report the case of a 8-year-old with childhood cerebral X-linked ALD who developed inattention, hyperactivity, motor incoordination and hemiparesis. We diagnosed ALD with elevated plasma very long chain fatty acid level and diffuse high signal intensity lesions in both parieto-occipital white matter and cerebellar white matter in brain MRI. We identified a novel c.983delT (p.Met329CysfsX7) mutation of the ABCD1 gene. There is no correlation between X-ALD phenotype and mutations in the ABCD1 gene. Further studies for searching additional non-genetic factor which determine the phenotypic variation will be needed.
Soybean is an important sources of plant proteins for human and animal nutrition. The use of soybean proteins has been expanded in the food industry due to their excellent nutritional benefits. But, Soybeans contain allergenic proteins that cause allergies to sensitive individuals. ${\beta}$-conglycinin(7S globulin) and glycinin(11S globulin) are the major components of storage protein in soybean. ${\beta}$-conglycinin consists of three subunits, ${\alpha}^{\prime}$, ${\alpha}$, ${\beta}$ and exhibits poorer nutritional and food processing properties than glycinin. There is a great deal of interest in the development of soybean lines with reduced amounts of ${\beta}$-conglycinin. The objective of this study was to determine the inheritance of ${\alpha}^{\prime}$-subunit protein in 7S globulin. F2 population was developed from the cross of "Jinpumkong2ho"(${\alpha}^{\prime}$-subunit presence) and PI506876(${\alpha}^{\prime}$-subunit absence) parent. Total 98 of F2 seeds were obtained and analyzed for the segregation of ${\alpha}^{\prime}$-subunit protein by SDS-PAGE. Among 98 F2 seeds, 70 F2 seeds showed ${\alpha}^{\prime}$-subunit protein and 28 F2 seeds did not show ${\alpha}^{\prime}$-subunit protein. The segregation ratios of 3 : 1 for presence and absence of ${\alpha}^{\prime}$-subunit protein were observed(${\chi}^2=0.667$, P=0.414). These data indicate that presence and absence of ${\alpha}^{\prime}$-subunit protein is controlled by a single major gene and might be useful for strain selection of 7S protein reduced soybean.
Purpose: A new health policy, referred to as the National Health Screening Program for Infants and Children, was launched in November 2007 by the Ministry of Health and Welfare and National Health Insurance Corporation in Korea. We have developed a nutrition-counseling program that was incorporated into this project. Methods: We reviewed the nutritional guidelines published by The Korean Pediatric Society and internationally well-known screening programs such as Bright Future in the United States. We also reviewed the recent Korean national surveys on nutritional issues, including the Korea National Health and Nutrition Examination Survey (KNHANES) and the 2005 National Survey of Physical Body and Blood Pressure in Children and Adolescents. The development of questions, pamphlets, computer programs, and manuals for doctors was carried out after several meetings of researchers and governmental officers. Results: We summarized the key nutritional issues according to age, including breastfeeding in infants, healthier complementary feeding, and prevention of iron deficiency anemia, establishment of healthier diets, as well as dietary prevention of overweight children with an emphasis on physical exercise. We have constructed a new Korean nutrition questionnaire and an anticipatory guidance program based on the primary care schedule of visits at 4, 9, 18, 30, and 60 months of age. Five to eight questions were asked at each visit and age-matched pamphlets for parents and guidelines for doctors were provided. Conclusion: We developed a nutrition-counseling program based on recent scientific evidence for Korean infants and children. Further research on this national program for screening the nutritional problems in detail and setting the therapeutic approaches may help identify areas of success as well as those that need further attention.

Purpose : Iron deficiency is still the most common nutrient deficient disorder despite the improvement in general health and nutrition. This study is designed to evaluate the dietary history of infants and young children with iron deficiency anemia(IDA) and the effects of nutritional counseling. Methods : This study was conducted on 120 children from 6 to 36 months of age with IDA. Their parents completed a questionnaire and took counsel for nutrition. IDA was defined as Hb <11.0 g/dL, ferritin <10 ng.mL or transferrin saturation <15%, or Hb increase >1 g/dL after iron preparation. The questionnaire consisted of their feeding patterns, weaning time and kinds of food. Results : In the 120 infants and young children aged from 6 to 36 months, the parents of 82 cases was counseled about nutrition. Fifty six infants among 82 cases have started weaning and the main foods of weaning were rice and/or rice gruel. Nutritional problems in weaning were that some children over one year of age were using a bottle, and parents restricted weaning food at will because of allergic disease or chronic disease. Most parents were satisfied with the nutritional counseling given from a clinical dietitian and showed good compliance. Conclusion : Many infants and young children with IDA were provided with non iron-fortified foods and made an inadequate wean. Most parents were satisfied with the nutritional counseling and showed good compliance. The need of dietary counseling was required for prevention and treatment of iron deficiency anemia because of inadequate weaning.
