Distribution and Morphologic Observation of Argyrophil Cells in Stomaches and Intestines of Lizards

Distribution and morphology of argyrophil cells in stomaches andintestines of three kinds of lizards were studied by means of Huang'smethod of argyrophil reaction on paraffin sections of intestine rolls.Theresults are as follows;The density of argyrophil cells is the highest inthree kinds of lizard stomaches,the density of argyrophil cells is higherin phrynocephalus frontalis and phrynocephalus versicolor duodenums,andEremias argus small intestine,the density of argyrophil decreases incolons and slightly increases in rectums.The argyrophil cells are rich inepithelium mucosae glands of stomaches and intestine glands and scarce inchoria.Some argyrophil cells can be found in the connective tissues oflamina proprias,being irregular in shape and possessing processes;thecytoplasms and processes are full of argyrophil granules,which sometimescan be found outside the cells.This indicates that argyrophil cells mayhave endocrine and exocrine functions.
