Scanning electron microscopic study of the white pulp of spleen in adult goats

The white pulp of the spleen in adult goats was thoroughly screened under the scanning electron microscope (VEGA3 TESCAN). The study revealed the presence of lymphoid and non-lymphoid cells. The T lymphocytes and B lymphocytes could morphologically be differentiated under the magnification of 8000 to 20000 times by scanning electron microscopy. The changes in number of cells in relation to the age was also recorded. The peri arterial lymphatic sheath and its structural connections with reticular cells and other non-lymphoid cells were clearly demonstrated. The types of lymphoid cells and their arrangement around the central arteries upto the marginal zones were observed in detail. A conclusion about the type of circulation in the spleen of goats was arrived after three dimentional observation of the tissue under scanning electron microscope.
