Abstract
Lamina propria mast cells and intraepithelial lymphocytes of ileum villi of the rat were examined under transmission electron microscope. The granules of mast cells were usually uniform in size, shape and electron density. Linear irregular whorls were also seen in some granules. The greatest diameter of the granules ranged from 500 to 800 nm. The sections of granulated lymphocytes contained each 1-12 granules. In contrast to the mast cell granules, the lymphocyte granules differed markedly in shape and size. A common finding was the appearance of cap sitting astride one end or side of the granules. The range of granule size was from 400 to 800 nm. Although the size of granules of the mast cells and intraepithelial lymphocytes fell into the same range, their structure differed significantly.
