Objective: To study various physiological and biochemical components of 65 cases cord blood and blood of 60 cases normal preschoolers.

Methods: The levels of serum complement and immunoglobulin and acute phase response proteins were studied by single immunodiffusion test. The levels of serum Ferr are tested by radioimmunoassay. The levels of the serum CH50 are tested by the quickly dull and stereotyped law of trace. The levels of serum CIC are tested by PEG turbidimetry quantitative analysis. The levels of ESR are tested by Westergren method. The levels of RBC-ZC and RBC-Z are tested by rosette rate of red cell zymosan C3b receptor and rosette rate of red cell zymosan, respectively.

Results: Comparing the results between neonate and preschooler. Contents of cord blood, such as serum HP、IgA、C9、IgM and CP are 20% less than that of preschoolers. serum α1AG, C1q, FN, C4, Bf and C5 are 50% less. PA, Pg, α1AT, C3, C1INH, Alb and Tf are 50~80% less. Serum CH50 is about 45% less. α2M, Ferr are very significantly higher. CIC is 0. ESR is significantly lower and the rosette rate of RBC-ZC and RBC-Z are very significantly higher.

Conclusions: The physiological and biochemical indexes of cord blood are usful for the judgement of neonatal infection in uterus and for prevention, treatment of neonatal disease and for preventive health care of neonate.
