Abstract:
Objective To study the role of peptide with tyrosine(PYY) and ghrelin in infants by comparing the difference and correlation of PYY,ghrelin levels and body weight in preterm infants and full-term infants.Methods Radio-immunity was used to determine serum PYY and ghrelin levels in 20 preterm infants in their first,3rd and 7th days,and also in 20 full-term infants at the 7th day.Body weight were recorded in the both groups.Then the levels of 2 hormone were analyzed the correlations with the body weight.Results Serum PYY and ghrelin levels increased remarkably in preterm infants as compared with those in full-term infants[full-term infants:PYY was(601.9?206.2) ng?L-1;ghrelin was(1 064.5?208.6) ng?L-1;preterm infants:PYY was(812.4?153.8) ng?L-1;ghrelin was(1 485.4?409.2) ng?L-1,Pa
