Tissue changes of the snail host caused by these parasites in different developmental phases have been observed in different organs, including
digestive gland, kidneys and ovotestis (Souza et al., 1995; Brandolini and Amato, 2006; Pinheiro et al., 2009).
Only the histology of select organs, including the foot, buccal mass, verge (penis), anus, gill, style sac, kidney, gonad, and
digestive gland, has been described (Avila-Poveda et al.
For biochemical and enzymatic analysis muscle,
digestive gland, gills, and mantle were excised and maintained at -80[degrees]C.
Such mollusks accumulate elevated levels of heavy metals, especially Cd, in the
digestive gland. Cadmium accumulation by squids occurs regardless of their exposure to anthropogenic contamination [4, 7] and these cephalopods end up transferring this metal to cetaceans, as they constitute an important source of food for these mammals [2].
Proteinase mRNA in tissues, other than the
digestive gland, suggests potentially different roles besides digestion during ontogeny.
Histochemistry of the
digestive gland of the pearl oyster Pinctada imbricata (Pterioida: Pteriidae) during the gametogenic cycle, Venezuela.
The
digestive gland was destructed while daughter sporocycts which contain many developing cercariae were noticed.
The aim of this study was to determine the concentration of Cd, Cr, Cu, Fe, Mn, Pb and Zn in gill,
digestive gland, arm and mantle tissues of male and female short-finned squid and to assess the health risks from exposure of metals to consumers through consumption of the local squid I.
Digestive gland beige, located along inferior region of each visceral whorl, covering middle digestive tubes and also two whorls posterior to stomach.
californica is the red algal chloroplast (or rhodoplast), which is catabolised in digestive vacuoles in a specialized cell type, the rhodoplast digestive cell, in the animal's
digestive gland. The rhodoplast digestive cell is a morphologically distinct cell type in the
digestive gland of A.
Two replicate samples were prepared from the
digestive gland / gonad complex of five male and female snails in each sample, which were analyzed for FAs by Gas Chromatography Mass Spectrometry (GC-MS) method.
The reduction of all of these sources of nutrients in invertebrates caused a reduction in the body weight, changes in the histologic structure of
digestive gland, oxygen consumption rate, and changes in the structure and composition of the shell.
digestive gland - any gland having ducts that pour secretions into the digestive tract
