  • While attempting to develop low salt, low fat and high fibre chicken nuggets, the effect of partial (40%) common salt substitution and incorporation of chickpea hull flour (CHF) at three different levels viz., 5, 7.5 and 10% (Treatments) in pre-standardized low fat chicken nuggets (Control) were observed. Common salt replacement with salt substitute blend led to a significant decrease in pH, emulsion stability, moisture, ash, hardness, cohesiveness, gumminess and chewiness values while incorporation of CHF in low salt, low fat products resulted in decreased emulsion stability, cooking yield, moisture, protein, ash, color values, however dietary fibre and textural properties were increased (p<0.01). Lipid profile revealed a decrease in total cholesterol and glycolipid contents with the incorporation of CHF (p<0.01). All the sensory attributes except appearance and flavor, remained unaffected with salt replacement, while addition of CHF resulted in lower sensory scores (p<0.01). Among low salt, low fat chicken nuggets with CHF, incorporation CHF at 5% level was found optimum having sensory ratings close to very good. Thus most acceptable low salt, low fat and high fibre chicken nuggets could be developed by a salt replacement blend and addition of 5% CHF.

  • This study examined the characteristics of the foodservice menu items offered at senior welfare centers to provide information on Korean senior menu development. A total of 514 lunch menu items were collected from 27 senior welfare centers in April, July, October and January. The most frequently served staple foods, soups, and side dishes were multi-grain rice, seaweed soup, Bulgogi, Kimchi, and liquid yogurt. The proportions of carbohydrate, protein, and lipids of total energy serving of senior welfare centers were 59.8%: 16.7%: and 22.8%, respectively. The nutrients served at less than 40% of the Recommended Nutrient Intake (RNI) and Adequate Intake (AI) of Dietary Reference Intakes for Koreans (KDRIs) were chloride (1.0%), vitamin D (1.3%), biotin (1.7%), magnessium (4.5%), Iodine (7.5%), pantothenic acid (8.0%), vitamin E (12.5%), vitamin $B_6$ (20.0~21.4%), vitamin K (21.1~24.3%), and water (35.7~39.7%). The nutrients served in excess of the daily intake goal and RNI were iron (98.9~127.1%), sodium (104.9%), and copper (1,100.0%).

  • 연근의 에탄올 추출물이 과당 유도 고혈압 백서의 신장 기능에 미치는 영향을 관찰하고자 뇨량과 전해질 배설량, 혈장의 creatinine, creatinine 청소율, 자유-수분 재흡수량 등을 측정하였다. 그 결과 연근은 과당 유도 고혈압 백서에서 나타나는 전해질 배설량의 변화를 개선시키는 효과는 없는 것으로 나타났고 단지 삼투질 농도의 배설량에만 약간의 개선 효과를 보였다. 신장의 가장 중요한 기능중 하나는 여과 기능이고 이를 나타내는 지표는 사구체 여과율인데, 고혈압 백서에서 혈장내 creatinine 농도가 증가하였고, creatinie 청소율이 크게 억제되었으나 연근추출물 투여 후 사구체 여과율의 감소가 회복되었다. 그러므로 연근은 과당으로 유도된 고혈압 흰쥐의 사구체 여과율을 개선시키는 것으로 사료된다.

  • In this experiment forty-eight Sprague Dawley male rats were chosen and used in order to measure the growth rates and to see the effects of lead acumulation in their organs resulting from variously controlled lead protein diet. Protein sources were casein and isolated soyprotein (ISP), and each source was divided into three groups : 7% low protein [LP], 20% standard protein (SP) and 40% high protein (HP) groups. The six experimental groups were given lead acetate(25 mg/kg B.W.) and six control groups were given sodium chloride by oral administration 6 times a week for weeks. The results from this experiment were summeraized as following ; 1) Food consumption, weight gain, organ weight and food efficiency ; Lead acetate administration with protein source had no effects on food consumption, weight gain and organ weight . By their different levels of protein, food consumption of LP group was less the that of SP and HP groups after 3 weeks, weight gain of LP group was less than that of SP and HO groups after 1 weeks. The organ weight in LP group was significantly lower than SP and HP groups except teeth and adrenal s. Effect of lead acetate administration on food efficiency have significantly lower in LP-ISP diet and HP -casein diet than other groups only first week. By their different levels LP group showed significantly lower than SP group until 3 weeks. 2) Hematopoietic effect ; The hematopoieteic effect was not influencec by lead acdtate administration and protein source. But the LP group showed a significantly lowe hematopoietic effect than the SP, HP, groups. 3) Accumulation of lead in the liver, kidney, teeth by protein source showed no significantly differences. Accumulation of lead in blood, heart of LP group, spleen of LP and HP groups. femur of SP and HP groups fed with casein diet groups were significantly higher than fed with ISP diet groups. By their different levels of group showed generally higher than SP and HP groups. But accumulation of lead in teeth of HP group was high also.

  • Due to the shortage of the fingerling/juvenile mud loach, Misgurnus mizolepis in Korea, these fish have been imported from China. However, the mortality rate during and after their transportation is very high. In this study, we examined various physiological and histological parameters to evaluate the effect of salt treatment on the survival and recovery of mud loaches in holding farms during the quarantine process. Glucose, osmolality, $Na^+$, $Cl^-$, and histological changes were assessed for three different salinities. Non-treated fish (control 0.0%) exhibited lower levels of osmolality, and $Na^+$ and $Cl^-$ concentrations compared with those kept in solar salt solution (0.5% and 1.0%). Glucose levels in control fish were higher than those in fish exposed to 0.5% and 1.0% solar salt solution. Histologically, control fish showed thinner epidermis of skin, branchial hyperplasia and lamellar fusion with an abundance of eosinophilic granule cell-like cells. After solar salt solution treatment, damaged gill structures in the fish almost recovered within 5 days. The present study demonstrates that mud loaches transported from China suffer from skin and gill damage and physiological dysfunction which may increase the mortality and morbidity. Moreover, saline treatment might alleviate the stress responses and ionic/osmotic imbalances, and help heal gill damage.

  • We investigated diet supplementation with shiitake mushroom fruiting bodies on biochemical and histological changes in hypercholesterolemic rats. Six-wk old female Sprague-Dawley albino rats were divided into three groups of 10 rats each. A diet containing 5% Lentinus edodes fruiting bodies given to hypercholesterolemic rats reduced plasma total cholesterol, triglyceride, low-density lipoprotein (LDL), total lipid, phospholipids, and the LDL/high-density lipoprotein ratio by 34.33, 53.21, 75.00, 34.66, 25.73, and 71.43%, respectively. Feeding mushroom also significantly reduced body weight in hypercholesterolemic rats. However, it had no detrimental effects on plasma albumin, total bilirubin, direct bilirubin, creatinine, blood urea nitrogen, uric acid, glucose, total protein, calcium, sodium, potassium, chloride, inorganic phosphate, magnesium, or enzyme profiles. Feeding mushroom increased total lipid and cholesterol excretion in feces. The plasma lipoprotein fraction, separated by agarose gel electrophoresis, indicated that L. edodes significantly reduced plasma ${\beta}$ and pre-${\beta}$-lipoprotein but increased ${\alpha}$-lipoprotein. A histological study of hepatic cells by conventional hematoxylin-eosin and oil red-O staining showed normal findings for mushroom-fed hypercholesterolemic rats. These results suggest that shiitake mushrooms could be recommended as a natural cholesterol lowering substance in the diet.

  • Vitamin C (ascorbic acid) is an essential component for collagen biosynthesis and also for the proper functioning of the cardiovascular system in humans. Unlike most of the animals, humans lack the ability to synthesize ascorbic acid on their own due to a mutation in the gene encoding the last enzyme of ascorbate biosynthesis. As a result, vitamin C must be obtained from dietary sources like plants. In this study, we have developed two different kinds of transgenic potato plants (Solanumtuberosum L. cv. Taedong Valley) overexpressing strawberry GalUR and mouse GLoase gene under the control of CaMV 35S promoter with increased ascorbic acid levels. Integration of the these genes in the plant genome was confirmed by PCR and Southern blotting. Ascorbic acid(AsA) levels in transgenic tubers were determined by high-performance liquid chromatography(HPLC). The over-expression of these genes resulted in 2-4 folds increase in AsA intransgenic potato and the levels of AsA were positively correlated with increased geneactivity. The transgenic lines with enhanced vitamin C content showed enhanced tolerance to abiotic stresses induced by methyl viologen(MV), NaCl or mannitol as compared to untransformed control plants. The leaf disc senescence assay showed better tolerance in transgenic lines by retaining higher chlorophyll as compared to the untransformed control plants. Present study demonstrated that the over-expression of these gene enhanced the level of AsA in potato tubers and these transgenics performed better under different abiotic stresses as compared to untransformed control. We have also investigated the mechanism of the abiotic stress tolerance upon enhancing the level of the ascorbate in transgenic potato. The transgenic potato plants overexpressing GalUR gene with enhanced accumulation of ascorbate were investigated to analyze the antioxidants activity of enzymes involved in the ascorbate-glutathione cycle and their tolerance mechanism against different abiotic stresses under invitro conditions. Transformed potato tubers subjected to various abiotic stresses induced by methyl viologen, sodium chloride and zinc chloride showed significant increase in the activities of superoxide dismutase(SOD, EC 1.15.1.1), catalase, enzymes of ascorbate-glutathione cycle enzymes such as ascorbate peroxidase(APX, EC 1.11.1.11), dehydroascorbate reductase(DHAR, EC 1.8.5.1), and glutathione reductase(GR, EC 1.8.1.7) as well as the levels of ascorbate, GSH and proline when compared to the untransformed tubers. The increased enzyme activities correlated with their mRNA transcript accumulation in the stressed transgenic tubers. Pronounced differences in redox status were also observed in stressed transgenic potato tubers that showed more tolerance to abiotic stresses when compared to untransformed tubers. From the present study, it is evident that improved to lerance against abiotic stresses in transgenic tubers is due to the increased activity of enzymes involved in the antioxidant system together with enhanced ascorbate accumulated in transformed tubers when compared to untransformed tubers. At moment we also investigating the role of enhanced reduced glutathione level for the maintenance of the methylglyoxal level as it is evident that methylglyoxal is a potent cytotoxic compound produced under the abiotic stress and the maintenance of the methylglyoxal level is important to survive the plant under stress conditions.
