Comparison of IL12 concentration between experimental groups.
Comparison of IFN-γ concentration between experimental groups.
Histopathological section in spleen tissue across experimental groups shows; A: moderate follicular hyperplasia (black arrow) and focal aggregation of lymphocytes in dilated red pulp sinuses (red arrow); B: elongation of hypertrophied eccentric arteriole (black arrow) in reactive lymphoid follicle; C: congestion of blood vessel sinuses of red pulp (black arrow) contain histiocytic cells with focal aggregation (red arrow); D: dilatation of blood vessel sinuses of red pulp precipitated with amyloid-like material (arrow); E: focal precipitation of amyloid-like material (arrow). (H and E stain, 200X); F: activation of lymphoid follicles (arrow). (H and E stain, 200X); G: parafollicular infiltration of lymphocytes (arrow). (H and E stain, 200X); H: activation of white palp. (H and E stain, 400X); I: hyperplasia of lymphoid follicle (arrow). (H and E stain, (200X); J: hyperplasia of lymphoid follicle (arrow). (H and E stain, (200X); K: dilated red pulp blood vessels sinuses (arrow) contains mononuclear cells (histiocytes). (H and E stain, (400X); L: negative group shows normal lymphoid follicle in white pulp (arrow) and red pulp. (H and E stain, (100X). Panel A, B, C, D, E: Vaccine group; Panel F, G, H: Vaccine + adjuvant group; Panel I, J, K: positive control group; Panel K: negative control group.
