The Effect of Nutritional Support with Oral High Protein Liquid on Patients Who are Undergoing Radiotherapy for Lung Cancer

PURPOSE : Weight loss and malnutrition in patients undergoing radiation therapy for lung cancer are common problems. We evaluated the effect of nutritional support with administering oral high calorie, high protein liquid, Mediwell ProteinTM. MATERIALS AND METHODS : From Feb. 2007 to Aug. 2008, 21 patients with lung cancer received nutritional supplement for 4 weeks with Mediwell StandardTM (n=10) or higher protein liquid, Mediwell ProteinTM (n=11). Their nutritional statues were evaluated just before radiation therapy and after 4 weeks. RESULTS : Nutritional support with oral high calorie, high protein liquid, Mediwell ProteinTM, showed improvement of the nutritional status during radiation therapy for lung cancer, even though it was not statistically significant. CONCLUSION : Nutritional support with oral high calorie, high protein liquid was effective for maintaining the nutritional status of patients with lung cancer during radiation therapy

Effects of sn-2 palmitic acid-fortified vegetable oil and fructooligosaccharide on calcium metabolism in growing rats fed casein based diet

This study was carried out to investigate the efficacy of sn-2 palmitic acid-fortified vegetable oil (Sn2PA) on calcium absorption and to confirm the synergistic effects of fructooligosaccharide on calcium absorption. Male SD rats were fed 6 kinds of casein based diets containing vegetable oil (control), sn-2 palmitic acid-fortified vegetable oil (Sn2PA) and Sn2PA with fructooligosaccharide(Sn2PAFO) in two levels of calcium (normal 0.5% and high 1.0%) for 3 weeks. Total lipids, cholesterol, triglyceride and calcium in blood were measured. Feces were collected using cages for 4 days. Serum concentrations of total lipids and calcium were not significantly different among groups. However, serum triglyceride was significantly decreased by fructooligosaccharide supplementation regardless of dietary calcium level. The lipid absorption was not significantly different among experimental groups. Calcium absorption was significantly higher in Sn2PAFO group than other groups. Calcium solubility of intestine was increased by sn-2 palmitic acid supplementation. These results suggest that sn-2 palmitic acid and fructooligosaccharide supplementation could be beneficial for baby foods including infant formula, with regard to increasing absorption of calcium by more soluble calcium in the small intestinal content.

Effects of Deer Antler Extract on Serum IGF-I, Bone Growth and Splenocyte Proliferation in Growing Rats

Although it has traditionally known that deer antler and medicinal herbs extract contain some functional components for health promotion, the nutritional significance remains to be elucidated. This study examined the efficacy of deer antler extract (DA) , medicinal herbs extract (MH) and their mixture (DAMH) on serum IGF-I, bone growth with growing rats in vivo and splenocyte proliferation with spleen cells in vitro. Three week-old young female rats (Sprague-Dawley) were divided into 4 groups and then fed basal diet (AIN-93G) or experimental diets containing DA, MH, DAMH, respectively, for 7 weeks. We collected blood, liver, kidney, spleen, femur and tibia from rats. There was no significant difference in weight gain, but food intake increased in DA- and MH-fed groups. There were no signs of liver and kidney damage in the DA, MH and DAMH-fed groups compared to basal diet group. In femur and tibia, wet weights, breaking forces and bone minerals (Ca, Mg and Zn) were significantly higher in the DA-fed group than in the other groups. Serum alkaline phosphatase (ALP) , bone-specific alkaline phosphatase (BALP) activities were significantly lower in the DA, MH, DAMH-fed groups than in basal diet group. Also, serum insulin-like growth factor-I (IGF-I) concentrations were significantly increased in DA-fed group compared to the other groups. Therefore DA was shown to have an activity of bone growth promotion by increasing the IGF-I, a major bone growth factor. The deer antler extract showed an enhanced immune action on the primary cultured-cells from spleen of rats, representing that splenocytes were proliferated by lipopolysaccharide (LPS) , but not by concanavalin A (Con A) . These results indicate that deer antler extract has beneficial effects on bone growth via IGF-I and on splenocyte activation.

Therapeutic Effect of Anti-Rotavirus Chicken Egg Yolk Immunoglobulin (IgY) on Diarrhea by Infection of Rotavirus / 소아과

PURPOSE: Rotavirus is an enteric pathogen that affects millions of children globally each year. But no specific therapy is available for the management of rotavirus diarrhea. Due to the clear need to define improved modality for treatment of rotavirus diarrhea, we evaluated the efficacy of anti- rotavirus IgY in the treatment of infants and children with gastroenteritis. METHODS: First, the amount of viral particle in the stools of thirteen patients (seven were given IgY, 6 placebo) infected by rotavirus were evaluated for 3 days with the quantitative RT-PCR method. Second, 36 children with known rotavirus infection identified by ELISA or semi-quantitative RT- PCR were evaluated. We gave 5 g anti-rotavirus egg yolk daily in two equally divided doses for 3 days to two groups (an 18 IgY group and an 18 placebo group), respectively after parenteral consent. Daily vomiting frequency, stool frequency, oral intake and urine output were monitored for 3 days, and electrolyte and blood chemistry were checked at the first and third days. RESULTS: First, in the placebo group, the amount of virus particles increased daily, but in the IgY group it decreased daily. Second, when IgY and placebos were given to children infected with rotavirus, diarrhea on the third day decreased significantly in the IgY group, compared with the placebo group. CONCLUSION: Treatment with antirotavirus immunoglobulin from immunized chicken's egg resulted in a decrease in the amount of viral particles in stools and diarrhea frequency in children. These results suggest that anti-rotavirus IgY is effective in the treatment of rotavirus gastroenteritis.

Effects of Maeil Human Milk Fortifier on Growth and Bone Mineralization in Preterm Infants

PURPOSE: A prospective, controlled trial was conducted to evaluate growth, bone mineralization, and nutritional status receiving preterm human milk supplemented with a newly formulated Maeil human milk fortifier. METHODS: Twenty five fortified human milk-fed and preterm formula-fed infants with a birth weight < 1, 800 g and gestational age <35 weeks, who were born at Ajou University Hospital from March, 2003 through August, 2004 were studied. Growth, biochemical indices of bone mineralization, feeding tolerance, morbidity and wrist X-ray were assessed serially. Total body bone mineral density was measured by dual energy X-ray absorptiometry at 2 and 5months of age. RESULTS: There were no differences in growth, including weight, height and head circumference, between two groups. Serum Ca, P, ALP and other biochemical indices were similar. Although low grade rickets (grade I and II) were occasionally found on wrist X-ray, the rate of occurrence and severity were similar. The bone mineral densities of both group showed no difference. CONCLUSION: The fortified human milk-fed infants and preterm formula-fed infants showed no difference in growth, and bone mineralization. This newly formulated Maeil human milk fortifier can be safely used in preterm infants.
