The prepubertal responsiveness of 3α-hydroxysteroid dehydrogenase and zeara-lenone-reducing activity to either a large subcutaneous dose of testosterone or dietary zearalenone was investigated in female rats. Testosterone induced both the activity of the 3α-hydroxysteroid dehydrogenase, with androsterone as substrate, and zearalenone reduction to α- and (β-zearalenol. Zearalenone had no effect on the activity of 3α-hydroxysteroid dehydrogenase, but had a slight inducing effect on the zearalenone reduction to β-zearalenol. Both testosterone and zearalenone had a growth-promoting effect on uterus. |
