Uptake of 3H-norepinephrine in human female reproductive organs
3H-NA was administered to five nonpregnant and 12 pregnant women during the first half of gestation. The rate of disappearance of 3H and 3H-NA was very fast and did not differ between the pregnant and nonpregnant women. The fallopian tubes had a higher uptake capacity for 3H-NA than the uterus. The uterine and ovarian tissues of the nonpregnant patients had a higher uptake capacity for 3H-NA than the corresponding tissues of pregnant women. However, according to the present results, the function of the adrenergic uptake mechanisms in the puerperal organs differs only slightly from that of the nonpregnant organs during the first half of pregnancy.
