, with basal nucleus and cytoplasm filled with secretory vesicles (Fig.
The presence of mucous cells
were considered only in those cases where mucous cells
were found in the areas devoid of moderate to severe inflammatory cell infiltrate in order to exclude the possibility that mucous cell
metaplasia may have resulted from an inflammatory process.
In H pylori gastritis, MUC5AC expression on the surface epithelium is decreased and MUC6 expression extends to the surface mucous cells
. (1,3) With regard to MUC1 expression, controversial results have been reported.
The exudation of mucus secretion would finally lead to a desiccation of the snail, and loss of mucous cells
would prevent production of the very mucus that protects the surface of the snails from desiccation (Triebskorn & Kunast 1990).
The epithelial lining of the secondary lamellae comprised epithelial pavement cells, few mucous cells
and pillar cells.
Mucous neck cells generally distributed in the neck of the glands, occasionally single neck mucous cell
at the bottom and body of the glands.
The mucous cells
were only slightly stained whit AB and reacted strongly to PAS.
Serous cells in reptiles and only mucous cells
in amphibians, and mucous cells
developed before the serous cells; it has been reported that mucous cells
may be pioneer cells in serous glands in phylogenetic terms (Junqueira et al., 1967).
Ciliated and mucous cells
(resembling goblet cells) are often intermixed and lay on top or are surrounded by a uniform layer of basal cells.
On microscopic examination, the connective tissue stroma showed the presence of atypical epidermoid and mucous cells
, arranged in the form of a ductal island, cords, and strands.
These were then evaluated for histopathological variables which included thickness of epithelial lining, keratinization, foamy macrophages, mucous cells
, Rushton bodies, cholesterol crystals and haemosiderin.
cyprinacea, hyperplasia, an increase in mucous cells
in the distal end of primary lamella, vacuolization in secondary lamella, necrosis of gill epithelium, distortion in cartilaginous tissue (Figure 3a), haemorrhages and hyperplasia at the base of the gills (Figure 3b); thickening of dermis, degeneration and necrosis in the skeletal muscle, infiltration of a massive number of inflammatory cells in the dermis and skeletal muscle (Figure 3c); granuloma like growths formed by collagen fibrils of dermis (Figure 3d) and also parasitic sections surrounded by fibrous connective tissue in the muscle tissue were observed (Figure 3e).
