Serum Fat Soluble Vitamins in Bile Duct Ligated Rats / 대한소아소화기영양학회지

PURPOSE: The aims of this study are to measure the serum levels of fat soluble vitamins (vitamin A and D) from bile duct ligated rats, and to evaluate the effect of oral bile acids administration to facilitate absorption of fat soluble vitamins. METHOD: We measured serum ALT, total bilirubin, vitamin A, and vitamin D of Sprague-Dawley rats 1 week before and 4 weeks after experimental bile duct ligation. Rats were consisted with 3 groups. Group 2 had been find bile acids and group 3 ursodeoxycholic acid after operation for 4 weeks. Multi-vitamin was given to all groups. RESULTS: 1) Base line (mean value before duct ligation): ALT 74.2 IU, total bilirubin 0.26 mg/dL; vitamin D 13.01 ng/mL vitamin A 0.87 microgram/mL, total bile acids 25.16 micron mol/L. 2) Four weeks after ligation: ALT 100.7 IU, total bilirubin 2.58 mg/dL; vitamin D 7.89 ng/mL vitamin A 1.37 microgram/mL, total bile acids 278.22 micron mol/L. 3) 4 weeks after ligation, each group (group 1, group 2 and group 3) showed vitamin D (7.62, 8.10 and 7.99) ng/mL, vitamin A (1.68, 1.06 and 1.33) microgram/mL, total bile acids (233.17, 345.80 and 268.57) micron mol/L, which were statistically not significant. CONCLUSION: Serum level of vitamin A is increased after bile duct ligation although vitamin D is decreased. Oral administration of bile acids does not affect the serum levels of vitamin A and D in bile duct ligated rats.

Study of the Analgesic Effect of Sucrose and Non-sucrose Sweet Substances(Aspartam, Dextrose) in Full Term Neonates

PURPOSE: During the first days of life, neonates born in Korean hospitals typically encounter a number of stressful and painful events. In recent investigations, it was shown that there is a dose-response effect of increasing concentration of sucrose, resulting in reduction in crying time in healthy full-term infants. We assessed the use of sucrose to reduce pain in neonates with routine blood sampling by heel prick and the use of non-sucrose sweet substances(Aspartam), Dexrtose which we use to reduce pain in neonates with the same procedure. METHODS: A total of 135 neonates born in the KonKuk University Hospital were randomly assigned to 9 experimental groups. 2ml of the test solution was given by syringe into the infant's mouth over less than one minute. After 2 minutes, the nurse lanced the infants heel immediately and gently squeezed two times, and then a bandage was applied to the wound and the foot released. Crying during sampling and during the three minutes after sampling(recovery phase) was recorded on audio tape and later the duration of crying was analysed blindly. RESULTS: There was a significant reduction in total crying time as compared with the controls. There was a significant reduction in first crying time as compared with the controls. There was a significant reduction in crying time at the end of each minute in all the groups as compared with the controls. There was no significant difference in heart rate and oxygen saturation. CONCLUSION: We conclude that sucrose, aspartam and dextrose induce an effective analgesic effect in neonates.
