Daily administration of thyrox-ine (200 μg/100g/BW 24 hr s.c.) to intact suckling rats (from 7 to 13 days of postnatal age) and to suckling adrenal-ectomized rats (from 14 to 18 days) caused a precocious decrease of acid-β-galacto-sidase, β-glucuronidase and N-acetyl-β-glucosaminidase in the ileum of the small intestine. Thyroxine treatment evoked also a precocious increase of jejunal sucrase and maltase activities.
