title: [Aspartate and alanine aminotransferase activity in the adrenal cortex of human embryos and fetuses].
abstract: Aspartate aminotransferase was detected in the adrenals of 6-7-week human embryos, the activity being the highest at the 7-9th and 12-14th weeks. Alanine aminotransferase was found in 15-week foetuses. During all the period investigated (6-28 weeks), the activity of aspartate aminotransferase was found to be higher than that of the second enzyme. The activity of both enzymes is higher in female foetuses than in male ones. However, age changes in the activity of both enzymes in male embryos and foetuses were of the same sign as in female ones.
