So this study was performed to clarify the relation between Structure and function of immune organ. In the present investigation an immunocytochemistry procedure was used to examine the distribution of T and B cell and macrophage populations in the thymus spleen and lymph nodes. Most of lymphoid organ showed decreased pattern of Ly1 positive T and IgM positive B cells. Macrophage positive cells were deceased in vivo. The present study gives an overview on the immune organ structure and function of Apodemus agrarius Pallas.
