From the previous studies, F-P-4 formula was found to be comparable to full fat dry milk in its nutritive value and feeding performance. However, an attempt was made in order to make sure whether or not any possibility might exist, by which further improvement of nutritive quality and simultaneous reduction of product costs may be achieved. Using F-P-4 as a control, modifications were made in new formulas, F-P-5, F-P-6 and F-P-7 by reducing FPC, eliminating yeast from the mixture, and by enriching with methionine as needed. In particular, F-P-7 is completely free of FPC, hydrogenated oil and yeast. Yet, levels of total protein and fat were kept equal to those of F-P-4 in all formulas. An animal feeding test for all formulas using 10 female rats per group for 8 weeks and an infant feeding trial for F-P-5 and F-P-6 with 5 of each female infants under age of one for one month were conducted along with F-P-4 as a control. Almost the same results were obtained with F-P-4, 5 and 6, but F-P-7 showed the lowest body weight gain. FER of F-P-5 and 6 was 0.20 as was with F-P-4, while that of F-P-7 was 0.16. Acceptability to infants was excellent; growth, appearance and biochemical data were normal. As an example F-P-4 packed in 0.04mm polyethylene bags was used for storage study at $25^{\circ}C$ and relative humidity of $65{\sim}85%$ for 8 months. Although viable bacterial counts and vitamin C contents were reduced, peroxide and TBA values were increased gradually during such storage. Since there are also significant changes in color and organoleptic quality, the expected shelf life under the given conditions is considered to be about 2 months and thus further works are needed both on the product and packaging in order to improve the storage stability. Either elimination of yeast form F-P-4, that is F-P-5, or partial replacement of FPC with methionine, that is F-P-6 may well reduce material costs about 10%. Considering blending process of ingredients, F-P-5 is thus found to be the best formula developed. While F-P-7 free of FPC is inferior in its nutritive quality than that of others, but significantly superior than of rice. Furthermore, the material cost of the product can be reduced about 20% from that of F-P-4. And thus this vegetable blend is considered to be useful as a low cost supplementary food mixture for growing children.

This study was performed to investigate the effect of germinated Ilpum rough rice extract on blood glucose in C57BL/KsJ-db/db mice. The mice were divided into several groups: normal control (NC), diabetic control (DC), those fed with 0.25% germinated Ilpum rough rice extract (DM-0.25%GIRRE), those fed with 0.5% germinated Ilpum roughrice extract (DM-0.5%GIRRE) and those fed with 1% germinated Ilpum rough rice extract (DM-1%GIRRE). After 8 weeks of treatment, body weight, water intake, and diet intake of the DM-1%GIRRE group were significantly lower than the other DM groups. Blood glucose levels of the DM-1%GIRRE group were significantly lower compared to the DC group. Fasting blood glucose HbA1c level and total glucose tolerance test were significantly lower in the DM-1%GIRRE groups compared to the DC group. There was no significant difference in serum insulin level among each group. Therefore, the results of this study demonstrate that germinated Ilpum rough rice extract alleviates many of the symptoms of diabetes in genetically obese mice and may offer a possibility as a therapeutic supplement for the normalization of blood glucose levels in humans with hyperglycemia. It may also have beneficial effects in patients with non-insulin-dependent diabetes mellitus.

Purpose : This study was done to analyze the changes in the clinical conditions and the diagnosis of hypertrophic pyloric stenosis. Methods : We report a retrospective clinical analysis of 39 patients with hypertrophic pyloric stenosis from Jan. 1992 to Aug. 2001. The age and sex distribution, family and birth history, clinical symptoms, the ultrasonographic and the operative sizes of pyloric canals were compared. Results : The body weight was below the 3 percentile at admission in eight cases(20.5%). "Olive like mass" in right upper quadrant was palpated during physical examination in 23 cases(59%) and gastric peristaltic wave observed in six cases(15%). The ultrasonographic measurements showed that the pyloric muscle thickness to be $4.95{\pm}0.99mm$($mean{\pm}SD$), pyloric diameter $14.42{\pm}2.64mm$, and pyloric length $20.17{\pm}3.92mm$. Fredet-Ramstedt pyloromyotomy was employed in all cases. The operative measurements of the pyloric muscle thickness was $5.11{\pm}1.01mm$, pyloric diameter $15.01{\pm}2.47mm$, and pyloric length $22.32{\pm}3.43mm$. Conclusion : There was no significant difference between the ultrasonographic and operative measurements. Currently, the hypertrophic pyloric stenosis patients showed lesser clinical hallmarks of the disease. The earlier diagnosis using imaging studies before development of significant metabolic abnormalities is becoming an important factor that change the future outcomes of hypertrophic pyloric stenosis.

This experiment was planned to develop a functional supplement by food resources to prevent and lessen the deleterious effects caused by environmental pollutants such as polluted food, air, water and heavy metals. The goal of this study was to investigate the effects of peking-duck extracts supplemented with six kinds of medicinal herbs (DJ) on the intoxication of lead and mercury in rats. Sprague-Dawley rat weighing $150g\pm15g$ g, were randomly assigned to 5 groups, basal diet only (NCG), heavy metal without DJ injection (HCG), heavy metals and DJ (3 mg/mL) injection (HMLD), heavy metal and DJ (30 mg/mL) injection (HMMD), heavy metal and D] (300 mg/mL) injection (HMHD). Mecury (Hg) and lead (Pb) injected at the level of 50 ppm for 17 days. Also DJ oral feeding was continued for 31 days. The result of this study were as follows; Food intake and body weight gain in heavy metal administered groups were lower than those of control group (NCG). The activities of GOT, GPT and BUN level were significantly reduced in DJ-treated groups as compared to HCG. DJ was shown to suppress the accumulation of Hg and Pb in serum. The results suggest that DJ might have protective effect on Hg and Pb intoxication.

The aim of the present study was to investigate the effect of combined extract of safflower seed with herbs on the improvement of blood glucose, lipid peroxides, lipids in the plasma and liver of strpetozotocin-induced diabetic rats. Rats in the experimental group were orally administered with combined extract of safflower seed (100 mg, 200 mg/kg B.W.) with herbs (Ophiopogon japonicus Ker-Gaqler, Glycyrrhiza uralensis Fisch, Mori Folium, Poria cocos, Rehmannia glutinosa, Eriobtrya japonica, Aralia continentalis Kitagawa, Zizyphus jujuba var, Cornus officinalis, Paeonia suffruticosa, Trichosanthes kirilowii Maxim and Schizandra chinensis Baill) for 4 weeks. Body weight gain and food efficiency ratio were significantly lower in diabetic groups than those of control group. These were no protective effect of the supplementation of combined extract of safflower seed with herbs. Concentration of blood glucose was significantly higher in the diabetic groups than those in the control group. Blood glucose concentration was remarkably lower supplementation of combined extract of safflower seed (200 mg/kg B.W.) with herbs. There was no significant difference of plasma lipid peroxides among experimental groups, while liver lipid peroxides of diabetic group was significantly higher in control group. But supplementation of combined extract of safflower seed with herbs was induced markedly lower in liver lipid peroxides in diabetic rats. Diabetic groups had markedly higher levels in triglycerides, LDL-cholesterol and atherogenic index, while had lower HDL-cholesterol level. Triglyceride levels of plasma and liver were significantly lower with combined extract of safflower seed with herbs. But total cholesterol, phospholipid and free fatty acid were no differing significantly among experimental groups.

The aim of this study was to evaluate the effects of Welsh onion administration on $CCl_4$-induced hepatic injury in rats. The increasing rate of the body and organ weight was not significantly different by the ad-ministration of the Welsh onion. Welsh onion (2, 4, $10\%$ w/w) was given for 4 weeks with the injections of $CCl_4$. Total serum lipid was significantly decreased in all treatment groups compared to $CCl_4$ only treatment group (p<0.05). The Welsh onion from winter season was more protective effect by lowering the serum levels of transminase (SGOT and SGPT) compared with others, the levels of transminase - phosphatase (ALP) in serum. The Welsh onion from winter at a dose of $4\%,\;10\%$ (w/w) showed significantly hepatoprotective activity which was comparable to that $CCl_4$-induced hepatic damage. Histological evaluation showed that Welsh onion partially prevented $CCl_4$-induced inflammation, necrosis and vacuolation. Pretreatment of Welsh onion reduced extent of the necrosis found 24 hr after the intraperitoneal administration of $CCl_4$. The present study shows the liver protective action of the Welsh onion against experimentally induced liver damage in rats. This suggests that the Welsh onion may be used as an effective hepatoprotective agent.

Osteoporosis that is associated with estrogen deficiency in menopause is by far the most common cause of age-related bone loss. Since isoflavone had been reported as a natural substance that minimizes bone loss, we have begun this study to examine the effect of the substance on bone metabolism in ovariectomized rats. Five week-old (n=22) and 25 week-old (n=22) Sprage-Dawley female rats were classified into young (Y) and adult (A) groups. Each group consisted of three subgroups : sham operated group (SH), ovariectomized group (OVX), and isoflavone supplemented group (OVX+ISO 80 mg/kg B.W.). They were fed chow for 9 weeks. The result showed that body weight gain was increased in YOVX in comparison to YSH group, (p<0.05) serum osteocalcin concentration and urinal deoxypyridinoline (DPD) excretion had significantly increased in YOVX more than in YSH group, and significantly decrease in OVX+ISO than in YOVX group (p<0.05). We concluded that soy isoflavones may decrease bone turnover in young rats. However, isoflavone supplement didn't show significant influence on bone metabolism of adult rats.

This study was undertaken to investigate the effects of meal pattern on lipogenesis and activities of lipogenic enzyme in rats epididymal and mesenteric adipose tissues. A high fat diet was fed either ad libitum or in 1 meal during the last 3 h of the dark cycle for 4 weeks. Lipogenesis was measured as glucose conversion to total lipid and activities of glucose-6-phosphate dehydrogenase (G6PDH), 6-phophogluconate dehydrogenase (6PGDH) and NADP-malate dehydrogenase (ME) were determined by measuring NADPH production. Lipoprotein lipase (LPL) activity and serum lipoprotein concentrations were also measured. Meal-fed (3 h) rats had a decreased food intake, body weight and carcass fat compared with rats fed ad libitum. The serum triglyceride concentration of meal-fed rats tended to be higher than that of the ad libitum rats. However, there were no differences between meal-fed group and ad libitum group in serum concentrations of HDL-cholesterol, LDL-cholesterol and total-cholesterol. Rates of lipogenesis in both epididymal and mesenteric adipose tissues were significantly higher in the meal-fed group than that in the ad libitum group. In addition, meal-fed group showed higher G6PDH, 6PGDH and LPL activities in both epididymal and mesenteric adipose tissues, but exerted no significant effect on ME activity. These results suggest that meal-fed rats compared with ad libitum rats have marked lipogenic capacity, although such elevation probably does not result in increase in carcass fat concentration. Thus, meal-fed diet can be an important determinant of the alterations in adipose lipid metabolism.

To study the effects of substances in paeonia seeds (Paeonia lactiflora Pall.) on lipid metabolism, crude methanol extract and secondary ether-soluble fraction out of defatted methanol extract and trans-resveratrol were prepared from the seeds and added to 0.5% (w/w) cholesterol diets for rats. Male Sprague-Dawley rats weighing 120$\pm$11 g were divided into six experimental groups: control group with no extra supplement, 0.1% (MP1) and 0.2% methanol extract (MP2) supplemented groups, 0.05% (EP1) and 0.1% ether-soluble fraction (EP2) supplemented groups and 0.02% resveratrol supplemented group. Experimental diets were fed ad libitum to the rats for 3 weeks. Body weight gains and food efficiencies were not different among the six experimental groups. Relative liver weights were lower in EP2 group compared to those in control group, but serum GOT and GPT levels of paeonia seed groups including trans-resveratrol group were not different from those of the control group. Serum total cholesterol levels reduced in EP2 and resveratrol groups but HDL-/total cholesterol ratios significantly increased in the four paeonia groups except EP1 group compared with the control group and serum triglyceride level lowered only in EP2 group than that of the control. However, liver cholesterol levels lowered in the five paeonia groups but triglyceride level lowered in MP2, EP1, EP2 groups than that of the control group. Fecal cholesterol excretion significantly increased in MP2, EP1, and EP2 groups than that of the control group, but bile acid excretions were not changed except that a reduction in EP2 group. These results suggest that paeonia seeds contain substances improving serum lipid status mostly via HDL pathway and resveratrol as monomer is one of the effective components but others including resveratrol oligmer are involved in the lipid improving effect.

This study has been carried out to estimate mean concentration and the daily intake of 2 artificial sweeteners (aspartame and sucralose) by analyzing food samples. Total number of samples was 755 and the number of samples detected for sweeteners was 33 (detection rate was 4.4%). Contribution rate to total estimated daily intake (%) of artificial sweeteners in food categories was high in candy for aspartame and sucralose. Total Estimated Daily Intakes $({\Sigma}EDI)$ for different age groups were high in $13{\sim}19$ years old for aspartame and $7{\sim}12$ years old for sucralose. Total estimated daily intakes $({\Sigma}EDI)$ of men and women were 5.10 mg/person/day and 4.88 mg/person/day, respectively. Total estimated daily intakes $({\Sigma}EDI)$ of artificial sweeteners were shown as follows; 3.75 mg/person/day for aspartame and 1.27 mg/person/day for sucralose, respectively and assuming a body weight of 55 kg. These values were ranged from $0.15{\sim}0.17%$ of acceptable daily intake (ADI) evaluated by FAO/WHO and $1.0{\sim}21.4%$ of theoretical maximum daily intake (TMDI), and therefore, judged to be safe.
