Aquadag collecting in distal inclusions of type A digestive cells. (Toluidinc blue; scale 50 /xm; aq, aquadag.) Figure 5. Alkaline phosphatase activity after 1 hr of feeding following starvation. Wall of duct cecum (left top), primary duct (right top), secondary ducts (right), and distal border of basophilic cells (arrows) are positive; digestive cells are negative. (Scale 150 /tun.) Figure 6. Alkaline phosphatase activity after 6 hr of feeding following starvation. Basal portions of tubule cells are positive. (Scale 100 /xm.).
