Adult CDF albino rats were killed from 10 min to 6 hr after a single intravenous dose of HRP. Experimental and control tissues were reacted for peroxidase activity and processed for light and electron microscopy. At 10 min, all extracellular spaces of the secretion zone showed reaction product. A reaction was also seen around Tomes' processes and in a layer of enamel spaces in the region of thin enamel. At later times intervals, reactions around Tomes' processes were also seen in regions of… CONTINUE READING
