From 4 DAH (TL = 2.7F0.1 mm, n = 40), a PAS-positive reaction was observed in the
brush border in both intestines. The most intense reaction was observed in the anterior
intestine. Several positive granules in the supranuclear area of the enterocytes were
observed as well (Fig. 2D). The liver also showed a PAS positive reaction from this day
onwards.
