Absence of histophatological response to cadmium in gill and digestive diverticula of the mussel, Mytilus edulis. A planimetric study of the mean epithelial thickness (MET) of the molluscan digestive gland over the tidal (L.) and Mytilus edulis L. using a planimetric method. We found no significant variation in MET in all cases. sis, the epithelium of the digestive diverticula becomes thinner, resulting in the formation of atrophic diverticula Cited by:

The acid hydrolase arylsulphatase has been localized at the ultrastructural level in digestive cells of the marine musselMytilus edulis for control and phenanthrene-treated (µg/l) untreated mussels the activity was generally restricted to Cited by:
The tubules of the digestive diverticula are the only place where soluble matter is absorbed, in adult, larvae, or spat. Fine particles are ingested and digested intracellularly in the tubules of the digestive diverticula, the products of digestion carried away by amoebocytes, and useless matter rejected into the by: 87 87 2 2 R.

Moore Institute for Marine Environmental Research Natural Environment Research Council Prospect Place, The Hoe PL1 3DH Plymouth Devon England Abstract The effects of increasing salinity on the ultrastructural morphology of the lysosomal-vacuolar system in digestive cells of the common mussel Mytilus edulis were investigated in order to relate structural changes.

Light and electron microscopic studies of the acute and chronic toxic effects of N-nitroso compounds on the marine mussel, Mytilus edulis (L.). by: Therefore, further studies must be carried on elsewhere and the results compared with these before conclusions may be drawn with any degree of certainty.
A direct relationship between the quantity and nature of the stored food material in the digestive diverticula and the seasonal variations in the plankton has been definitely : W.
Forest Whedon. The acute (1) and chronic (2) toxic effects of N-nitrosodimethylamine (DMN) were studied by light and electron microscopy upon injection of the chemical into the foot of mussels, Mytilus edulis (L.).Cited by: Digestive rhythms in the mussel Mytilus edulis Digestive rhythms in the mussel Mytilus edulis Langton, R.
Mytilus edulis L., collected from a m i d - t i d e level on the shore, showed rhythmic changes in m a n t l e fluid pH, crystalline style pH, style length and total protein, and in the amylase activity in the digestive gland.
A primary culture of a mixed-cell population from the digestive gland of the marine mussel Mytilus edulis L. was developed for potential use in toxicological studies. The blue mussel (Mytilus edulis) has been proposed for use as a sentinel organism to monitor the effects of marine pollution (Goldberg et al., ).
Recently, there has been interest in quantifying histopathological changes in mussel tissues, as one indicator of pollution-induced stress. Cadmium is a common and toxic aquatic pollutant. mussel Mylilus edulis L.

Three weeks after a 24 h exposure to zinc ( mg/1) the concentrations in common mussels (Mytilus edulis) varied from to pg/g DW. study, all the histopathological observations, includ ing single cases, are described because of the lack of histopathological data on Baltic mussels.

Various freshly isolated or cultured cell types have been used from molluscan species in toxicological studies, including digestive gland and blood cells of the common mussel, Mytilus edu 18, brown cells of the clam Mercenaria mercenaria, and heart cells of the oyster Crassostrea by: Abstract.
The acute (1) and long-term (2) toxic effects of N-nitrosodipropylamine (NDPA) and N-methylnitrosurea (NMU) were studied by light and electronmicroscopy following injection of the chemicals into the foot of the mussels Mytilus edulis (L.)

Thinning of the digestive epithelium of marine molluscs may provide an index of environmental stress. Variability in epithelial thickness, as a consequence of the large variety of environmental and populational variables which could affect MET (Mean Epithelial Thickness), may counter the Cited by:
