Thyroxine (T4) and triiodothyronine (T3) injected into adult rats causes first an increase and then a decrease in lactase activity measured subsequently in intestinal homogenates of rat jejunum. These changes are not associated with any alteration in intestinal structure or enterocyte migration rate.
