Distribution and Morphologic Observation of Argyrophil and Argentaffin Cells in Stomachus and Small Intestine of Toad

A distribution and morphology of argyophil and argentaffin cells instomachus and small intestine of 20 toads were studied by means of Huang'smethod of argyrophil reaction and Sinph's method of argentaffin reactionson paraffin sections of intestine rolls,The results are as follows:Thedensity of argyrophil and argentaffin cells in toad small intestine is thehighest in the duodenum and stomachus pyloricus progressively decreasesfrom jejunum to ilem.The argyrophil and argentaffin cells are highestin epithelium mucosae of stomachus gland and intestinal gland and areseldom found in chorion.Some argyrophil and argentaffin cells can befound in connective tissue of the lamina propria.The cells are irregularin shape and possesses processes.There are argyrophil and argentaffingranules in perikaryon and the processes and occasionally outside the cells.Argyrophil and argentaffin cells may have both endocrine and exocrinefunctions.
