Biochemical composition of exocoelomic fluid in early human pregnancy.

摘要: Exocoelomic fluid (N = 25) and amniotic (AF) 17) were retrieved by transvaginal puncture from 30 normal pregnancies being terminated for psychosocial reasons between 5-13 weeks of gestation. Biochemical analyses performed on each sample including concentrations urea, total protein, potassium, sodium, creatinine, hCG, alpha-fetoprotein (AFP). The results compared with values in maternal serum obtained at the same time. Significant correlations found gestational age urea (P less than .005), protein .05), hCG .001) exocoelomic fluid. Significantly .05) higher levels during third month pregnancy second month. Urea concentration significantly .005 P .001, respectively) lower .001 .001), potassium sodium creatinine .01 AF, respectively. was AF serum. AFP level (both both fluids.(ABSTRACT TRUNCATED AT 250 WORDS)
