ABSTRACT
Objective To observe the effect of intravenous nutrition on blood serum triglyceride (TG),humoral immunity and cellular immunity function in premature infants.Methods Sixty premature infants were randomly divided into 3 groups:amino acid group (group A),amino acid plus medium-long chain fatty group (group B) and amino acid plus long chain fatty group (group C).Amino acid and the fatty were used on them from 24 hours after their birth,started from 1.0 g/(kg?d),increased progressively 0.5 g/(kg?d) until 3.0 g/(kg?d),totally 7 days.TG and immunoglobulin IgA,IgM,IgG,complement C3,C4 and T-lymphocyte subsets CD3,CD4,CD4/CD8 and NK cell were checked in the first day before treatment and the ninth day after treatment.Results Compared with before treatment,TG of 3 groups were elevated(Pa0.05).Compared with group A and B,NK cell in group C were decreased obviously(Pa
