Figure 5 : Ultrathin sections.

(A): Control group showing acinar cell with apical electron dense and electron lucent secretory granules (G), densely packed rough endoplasmic reticulum (Rr) and mitochondria(m).
(B): Duct (D) is lined by rounded nuclei (n) and has cytoplasmic granules (g). Note, intercellular desmosome (arrowhead) inbtween the duct cells.
(C): Operated group showing irregular heterochromatic nucleus (N), dilated rarified rough endoplasmic reticulum (Rr), electron dense secretory granules and electron lucent granules (G). Extensive cytoplasmic vacuolations (V) are seen in their cytoplasm.
(D): Showing irregular heterochromatic nucleus (n) of lining epithelium of interlobular duct with many electron dense granules (g). Notice intercellular desmosomes (arrowhead).
(E): Treated group showing some acini have heterochromatic nuclei (N), electron dense granules, electron lucent granules (G), and dilated rough endoplasmic reticulum (Rr). Other acinar cells have euchromatic nuclei (Nn).
(F): Dialated duct (D) appears with apparently normal lining cells(C). (Scale bar=2μm).
