A nutrition survey of 198 children, 6 to 12 years old, in the Song Myeon Elementary School and Sam Song Elementary School, located in remote villages of Gaesan county, Chung Buk province, was undertaken between July 11 and 16, 1988, to investigate dietary and nutritional status. Mean values of height, weight, sitting height, arm circumference, girths of chest, and weight for height were 98%, 96%, 101%, 94%, 103% and 98%, respectively, of Korean standards. Compared with the standards for Korean children and values for Yun Jung Elementary School children of Youido, Seoul, anthropometric data of subjects surveyed showed slightly lower results than the standards and further lower results than those of Yun Jung Elementary School children. mean hematocrit value was 39.8±3.1%. 15.3% of subjects were proven to be anemic according to the hematocrit criterion established by the WHO. Mean urinary urea nitrogen/creatinine ratio was 7.9±3.3. Energy and nutrient intake were 61.2 to 134.4% of the RDA's; except for intake of ascorbic acid, most nutrients were below the RDA's. Carbohydrate provided 72% of total energy intake; protein accounted for 11%; fat provided 17%. Family environment, anthropometric data and results of biochemical tests were positively correlated with nutrient intake. The survey emphasizes the need for a nation wide school lunch program.

The small and the large intestine of swine represent the organs that extract nutrients from feedstuffs through digestion and fermentation and that allow their absorption and incorporation into the blood circulation. Special attention is directed towards the small intestine of young pigs since the transition to a solid diet at weaning exerts major impacts on the structural and functional integrity of the small intestine. Dietary factors involved in postweaning changes of gut morphology and biochemistry such as removal of bioactive compounds in sows milk at weaning, anti-nutritional factors in weaner diets, dietary fiber and the role of voluntary feed intake will be elucidated. The microbial function of the large intestine which is carried out by a diverse population of microorganisms is dependent on substrate availability. Short chain fatty acids as main fermentation products contribute to the energy supply of the host but they are also important for the maintenance of the morphological and functional integrity of the epithelium in the colon. As a result of bacterial nitrogen assimilation in the large intestine, nitrogen is shifted from the urinary to the fecal excretion route thus saving metabolic energy to the pig because less ammonia would become available for conversion to urea.

This study investigated the effect of Corni Fructus(Cornus officinalis Sieb. et Zucc.) extract on hyperglycemia and renal function in streptozotocin-induced diabetic rats. Male Sprague-Dawley rats were divided into three groups including normal control(NC), diabetic control(DC), and diabetic treatment with Corni Fructus(DCF). Over a 4-week experimental period, Corni Fructus aqueous extract was administered orally at 500 mg/kg BW/day. The final fasting serum glucose, serum urea nitrogen, triglyceride, urinary total protein level, and relative weight of the left kidney in the DCF group were significantly lower than the DC group. Serum insulin level in the DCF group was higher than the DC group by 23%. The renal xanthine oxidase and superoxide dismutase activities in the DCF group were significantly lower than the DC group. The renal catalase activity in the DCF group was significantly higher than the DC group. In conclusion, these results indicated that Corni Fructus can reduce glucose level and prevent or retard the development of diabetic complication via its antioxidative effect and protecting against diabetic renal damage in streptozotocin-induced diabetic rats.

This study investigated the effect of Rehmanniae Radix preparata extract on the antioxidant enzymes of kidney and renal function in streptozotocin-induced diabetic rats. Male Sprague-Dawley rats were divided into three groups including normal control (NC), diabetic control (DC), and diabetic treatment with Rehmanniae Radix preparata (DRR). Over a 4-week study period, Rehmanniae Radix preparata aqueous extract was administered orally at 1124 mg/kg BW/day. The serum glucose level in the DRR group was significantly lower (P<0.05) than the DC group. The serum blood urea nitrogen in diabetic groups was significantly higher (P<0.001) than the NC group. The urinary total protein level in the DRR group was significantly lower (P<0.05) than the DC group. The renal xanthine oxidase activity in the DRR group was significantly lower (P<0.01) than the DC group. The renal catalase activity in the DC group was significantly lower (P<0.05) compared to the NC group and that was significantly higher (P<0.05) in the DRR group than the DC group. In conclusion, these results indicated that Rehmanniae Radix preparata can prevent or retard the development of diabetic nephropathy via its beneficial effects for correcting the hyperglycemia and favorable effects on antioxidant enzyme system.

This study aimed to verify the nutritional and curative effects of protein hydrolysate in rats with cysteamine-induced duodenal uncer. Duodenal ulcer rat model was established by intraperitoneal injections of cysteamine. Sprague-Dawley, female rats weighing approximately 200g were intraperitoneally injected twice cysteamine(13mg/100g BW) at intervals of 3h per day. This procedure was repeated 3$\times$at intervals of 3d. Animals fed on 10% casein diet for infection periods. After last injection, 4 kinds of diets(10% casein, 20% casein, 10% casein hydrolysate, 20% casein hydrolysate) were given. Gastric montility, trypsin activity in gastrointestinal content, retention rate of nitrogen, plasma total protein, albumin, amino-N, urinary urea nitrogen, creatinine and hydroxyproline were analyzed for nutritional effects of dietary nitrogen levels(10%, 20%) and sources(casein, casein hydrolysate). In duodenal ulcer rat model, there was no differences between 20% casein diet and 20% casein hydrolysate in the view of severeness of ulcer, gastric emptying rate, serum total protein, serum albumin, plasma $\alpha$-amino-N, UUN, creatinine excretion, GFR, nitrogen retention. On the other hand, rats on 10% casein hydrolysate diet group had more curative effect of the ulcer, higher plasma albumin concentration and nitrogen retention than 10% casein diet group. The casein hydrolysate diet group was lower trypsin activity in small intestinal content than the casein diet group, at both nitrogen levels(10%, 20%). The results suggest that protein hydrolysate be applied in diet therapy for the patients with gastrointestinal ulcer.

To evaluate the effect of the feeding program of brown rice flake with soy milk or cow's milk to school children in rural areas. The survey was conducted twice before and after practice of feeding in March and July of 1990. The survey covered a total of 87 children aged from 7 to 12 in Ypsuk elementary school located in remote village of Sangju county. Kyung Buk province and the branch school of Songmyun elementary school located in remote village of Goisan county. Chung Buk province. Family environment dietary intake anthropometric data and biochemical tests were examined. The results are summerized as follows: The mean balance and food diversity at lunch were significantly lower than those at breakfast and dinner. Mean daily energy and nutrient intakes were below the Korean RDA's except for intakes of niacin vitamin A and ascorbic acid Especially intake of calcium was not reached to 50% of Korean RDA's. Most of anthropometric data of subjects surveyed showed slightly higher results in summer than those in spring except for weight for height and sitting height for height. The percentage of anemic according to hematocrit criterion was not reduced during this period. however urinary urea nitrogen/creatinine ratio was improved. The conbined feeding program of brown rice flake with soy milk or cow's milk was not sufficient to support the children's growth. So the survey recommends the support of goberment to the school lunch program in the remote village.

A untrition survey of early childhood was undertaken among 102 rural young children, aged 3 to 6, attending three day care centers of Hongcheon-gun, Kangwon province, in July of 1987, to investigate dietary and nutritional status. The results were obtained as follows: Mean values of height and arm circumference ranged from 96 to 97% of the KSRI's standards. However, mean value of weight met 91% of that standard. Mean value of hematocrit was 37.3±3.5%. According to the criterion established by the WHO, 3% of the subjects were proven to be anemic. Mean value of urinary urea nitrogen/creatinine ratio was 13.8±7.6; the higher the age lower the ratio was shown. Intake of energy and nutrients ranged from 63 to 88% of the RDAs. Carbohydrate provided 68% of total energy intake; protein accounted for 14%; fat provided 18%. Energy intake was divided among breakfast, lunch supper and snacks in a percentage ratio of 21:35:26:18. The survey clarified that the day care feeding largely supplemented the inadequate dietary intakes of these young children at home. Family factors, anthropometric measurements, biochemical results were positively correlated with nutrient intakes. Authors with this study can be contributed, as a reference, to develop the community nutrition programs as well as improving the quality of day care feeding.

Three experiments were conducted with female Japanese Saanen goats to investigate the effects of rumen protected methionine (RPMet) on N utilization and whole-body protein turnover. Whole-body leucine flux from which whole-body protein turnover rates were derived was measured by primed- continuous infusion of L-[$^{15}N$] leucine in combination with gas chromatography-mass spectrometry. Throughout the experiments RPMet was added to a diet to supply 1.5 g DL-methionine per goat per day. Irrespective of the major N sources (i.e., protein or urea) in the diet, both N deposition and whole-body protein synthesis were increased (p<0.05), and urinary N excretion was decreased (p<0.05) by supplementing with RPMet, but not by supplementing with methionine. It was concluded, therefore, that under the present experimental conditions, the RPMet supplement was efficiently bypassed to result in enhanced body protein synthesis of the goat.

The application of rumen undegradable intake protein (UIP) on lactating dairy goats was studied. Thirty 2-year-old lactating dairy goats were selected and assigned to dietary treatments begun from the third week to the fourth month postpartum. Experimental diets were formulated into three, low (32% CP), med (35% CP) and high (38% CP), iso-nitrogenous (16% CP) and iso-energetic ($NE_L$ 1.68 Mcal/kg) UIP levels. Results showed that feed intake was not significantly different among the treatment groups. The milk yield in the High UIP group (3.17 kg) was significantly higher than the med (2.95 kg) and low UIP (2.45 kg) groups (p<0.05). The milk compositions, milk fat, milk lactose and milk solids-non-fat (SNF) showed no significant differences among the three treatment groups. The milk protein however was significantly (p<0.05) lower in the low UIP than in the other treatment groups. The milk urea-N was significantly (p<0.05) higher in the low UIP than in the other treatment groups. The mean serum aspartate amino transferase (AST), urinary-N and total protein concentrations were significantly (p<0.05) lower in the high and the med UIP groups than in the low UIP group.

Curcumin (CMN) is known to have beneficial role in anorexia, coryza, cough, diabetic wounds, and hepatic disorders apart from its inherent antioxidant effects. Therefore, the present study was aimed to evaluate antioxidant effect of CMN in prevention of nephrolithiasis in rats-induced by ethylene glycol (EG) and Vitamin D3 (Vit. D3). Male Wistar rats (175 - 200 g) were randomized in groups like control, EG + Vit. D3 induced nephrolithiatiatic rats, CMN treated rats, CMN + EG + Vit. D3 treated rats, Vit. E + EG + Vit. D3 treated rats. Urine was collected weekly throughout the experimental protocol and estimated for calcium oxalate (CaO) count. After completion of experimental protocol serum was estimated for blood urea nitrogen and creatinine. Both the kidneys were excised and used to evaluate levels of biomarkers of oxidative stress and calcium oxalate crystal deposition by histopathological studies. Administration of EG and Vit. D3 to rats resulted in increased oxidative stress, hyperoxaluria and renal deposition of CaO crystals. Supplementation with CMN improves kidney function, reduces elevated oxidative stress, urinary oxalate level and renal deposition of CaO which shows its protective action in nephrolithiasis. The increased deposition of stone in the kidney and stone forming constituents of nephrolithiatic rats were effectively lowered by treatment of CMN.
