For each sampling, the gills, digestive gland
, and mantle were dissected and immediately frozen in liquid nitrogen overnight, followed by storage at -80[degrees]C until further analysis.
Oesophageal insertion and intestinal origin united in anterior, left side of stomach, additionally having 3 narrow ducts to digestive gland
in the sa me region (Fig.
Alterations in the digestive gland
and shell of the snail Helix aspersa Muller (gastropoda, pulmonata) after prolonged starvation Comparative Biochemistry and Physiology Part A: Physiology, 115(1): 11-17.
In contrast, a second family of enzymes was highly expressed in the digestive gland
of Cyphoma, regardless of the gorgonian diet.
The digestive gland
was the main target organ, with concentrations generally 5- to 10-fold higher than those measured in foot and lung (not shown).
Similarly, digestive gland
from lobsters captured in the south arem of Sydney Harbour, Nova Scotia, contained 433-2240 [mu]g .
Each specimen was measured with a ruler, and the soft tissues, including gonad, digestive gland
, mantle, foot, and gills were placed in a histocassette.
Four lesions were identified in the digestive gland
of the exposed clams: tubular dilation or atrophy (TDA), macrophage aggregates (DMA), tubular cell necrosis (TBN), and inflammation (DINF) (Figure 3, Table 3).
The standard curve was comprised of supernatant of the homogenate of a single Amblema plicata digestive gland
in the following amounts of total protein: 0, 1.
ABSTRACT The aim of this study was to test the effect of copper supplementation in a formulated feed on the growth, feed efficiency, and nutritional composition of subadults Octopus vulgaris, with particular reference to the differences in the content of copper in the tissues (muscle, digestive gland
, and hemolymph).
starch, glycogen, chrysolaminarin) to subunits that can be readily absorbed within the digestive tubules of the bivalve digestive gland
are the most important enzymes secreted by the style (MacKenzie 2013).
The muscle and digestive gland
were then dissected out and rinsed with distillated water to remove remnants of other organs.
After 6 mo of captivity, the adult lobsters were weighed (wet body weight), and samples of their gastric juice, digestive gland
, and muscle were collected.
Besides its role in digestion, the digestive gland
participates actively in the molt cycle; it is the major site for storage of glycogen, fats, and calcium during premolt, and thus is a primary factor in the mobilization of these reserves when needed for subsequent molt stages.
During the final stage, the parasite undergoes sporulation, with mature spores being released into the digestive tubule lumen, disrupting the epithelial lining of the digestive gland
and potentially causing the oyster to starve to death (Kleeman et al.
