Figure 4: (a) Immunohistochemical expression of inducible nitric-oxide synthase in the spleen showing strong expression in the interfollicular area containing T-lymphocytes, plasma cells and macrophages and negative lymphoid follicle B lymphocytes (×400). (b) Lymph node showing strong inducible nitric-oxide synthase expression in lymphocytes, plasma cells and histiocytes (×400). (c) Strong inducible nitric-oxide synthase expression in hepatocytes (×400) with periportal inflammation (arrow). (d) Giemsastain of spleen showing macrophages contain Leishmania amastigotes (arrows) (×1000)
