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:

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.

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.
