Figure 2: A-D) Electron micrographs of duodenum from control rats: (a) villus central core, macrophages (Ma), lymphocyte (Lc), and plasma cell (Pc).X1450. (b) columnar enterocytes(Ec) with rounded nuclei(N) and mitochondria (M), note; lateral infolding (head arrows) filled with a flocculent material. X2600. (c) low electron density of enterocyte cytoplasm, short cisternae of rough endoplasmic reticulum (RER) closely associated with mitochondria (M), a mass of glycogen granules (Gl) apically to the nucleus (N). X19000. (d) Golgi apparatus (Go), also note, mitochondria(M) ,RER and primary lysosomes (Ly). X25000. |
