[Study of the glucose concentration in five vascular regions -- aorta, arteria pulmonalis, vena cava inferior, vena cava superior, vena hepatica -- in childhood (author's transl)].

Using the Beckman glucose analyzer, glucose concentration was determined in the serum of the fasting blood in five vascular regions -- aorta, arteria pulmonalis, vena cava inferior, vena cava superior, vena hepatica -- of 52 children (ages 2,5 months up to 14 years and 3 months, x = 6 years and 3 months, male = 28, female = 24) with a healthy metabolism. The comparison of the average values of the glucose concentrations determined in five vascular regions in childhood showed that the glucose concentration in the vena hepatica was statistically significant higher than in the other vascular regions. Moreover the comparison of the glucose concentrations revealed that the values in the vena cava inferior were statistically significant higher as compared to the values in the vena cava superior. The glucose concentrations in the arteria pulmonalis, the vena cava superior and the aorta were nearly equal. Compared with the older children, the younger children had in all the investigated vascular regions lower glucose concentrations.
