| Feeding is an important factor for the successful rearing of larvae of the crab species. Further information on the morphological features of the foregut may to reveal larval feeding behaviour and or/whether there is a lecithotrophy in some or even in all stages of the larval cycle. In the present study, the structural development of the foregut and their digestive functions were examined in larvae of two brachyurans, Uca vocator and Panopeus occidentalis, reared in the laboratory. During larval development, the foreguts of the larvae in the first and last zoeal stages and in the megalopa stage were microscopically examined, described and illustrated. The zoeal foreguts of both species were well developed, showing specialization with a functional... |

| Thirty three healthy, New Zealand rabbits, underwent a total gastrectomy via laparotomy and subsequent evaluation of gastric dimensions. Were measured the lengths of the lesser and greater gastric curvature, in addition to the largest diameters of the organ. They presented average overall length of the lesser and greater curvature, respectively 6.7 cm and 27.3 cm. In addition, open surgical specimen presented a total area of 172.6 cm2. The sample was divided into two groups by age to perform comparisons between weight and stomach measures. Group 1 consisted of animals with age equal or less than 138 days and group 2 those with more than 138 days. No significant differences were found between the groups. This may suggest the use of younger animals to... |

| The gross morphology of foregut was investigated and described in detail for four freshwater crab species: a pseudothelphusid, Fredius reflexifrons (Ortmann, 1897) and three trichodactylids - Sylviocarcinus pictus (H. Milne-Edwards, 1853), Valdivia serrata White, 1847, and Dilocarcinus septemdentatus (Herbst, 1783). In general, the gastric mills of freshwater crabs showed a similar degree of complexity in relation to other marine species of Anomura and Brachyura previously described in the literature. However, significant morphological differences were observed among the analyzed species, as in ossicle numbers, features and connection types. A total of 38 ossicles were described for S. pictus and V. serrata and 37 ossicles for D. septemdentatus and F.... |

| The digestive tract of crustacea is complex. It is composed of a shor t oesophagum, a stomach with two bags, and internal wall with appendags specialized in grinding of feeds. These hard mastication pieces represent the gastric mill. Setae, filters included in the stomach structure allow the separation between food particles and liquid compounds. Those one are coming over through filters and more on to the digestive gland tubules or mid gut gland. In this organ, several types of cells play specialized functions: absorption, enzyme secretion, stocking function. Some cells of a new type, with undefined function, may be neurosecretions function, have been described recently. The end of tubules of digestive gland exhibits cells with embryonic characteristics.... |

| The stomach of three species of non-human primates was investigated by lectin histochemistry to clarify the staining affinity and distribution patterns of their sugar residues. All gastric regions, with little differences between the deep and superficial parts of the same region, were rich in. in N-acetylglucosamine and/or neuraminic acid. Although, the superficial regions of the gastric mucosa were scanty in N-acetylgalactosamine, a- D-glucose and a -D-mannose, the deep parts of the gastric mucosa were rich in these sugars. In conclusion, there is a difference among the mucosubstances of surface and foveolar mucous cells, mucous neck cells, and gastric gland cells. This indicates heterogeneous composition of gastric mucus, or mucus molecules with... |

| The aim of this work was to analyze the stomach growth rate, variability of proportion and shape during prenatal period, as well as evaluation of final features differentiation process distinctive for perinatal period. It seems interesting to compare stomach growth analyzed in situ on post-mortem fetuses with results obtained by other authors evaluating this process in sonographic examinations. Research was conducted on 225 post-mortem fetuses 12th to 40 th week of fetal age. There were measurements of stomach total length, lengths of greater and lesser curvature and cardia and pylorus widths performed. We evaluated the thickness of stomach front wall and bottom and its total mass. Statistical analysis was performed using statistical program package... |

| ABSTRACT The morphology of stomach ossicles of decapod crustaceans provides valuable information on their phylogeny and biology. We herein described ten new ossicles in the foreguts of two trichodactylid crabs, Sylviocarcinus pictus (H. Milne-Edwards, 1853) and Valdivia serrata White, 1847, in addition to previously described 38 ossicles, which are also recognized and listed. Five specimens each of S. pictus and V. serrata were selected for morphological analysis of gastric ossicles. The stomachs were obtained after removing the carapace, and they were fixed in 10% formalin for 24 hours. After this procedure, the stomachs were immersed in a solution of 10% Potassium Hydroxide (KOH) and heated to 100 °C during 60 minutes for tissue maceration. At this... |

| Spring blooms of the toxic dinoflagellate Alexandrium tamarense in the Argentine sea produce shellfish toxicity through the parallytic shellfish poison (PSP)accumulation. The trace PSP content in the mackerel Scomber japonicus liver was previously demonstrated in the Buenos Aires province coastal region (Carreto et al, 1993a),and a certain capability to accumulate the toxins was suggested.However, it was up to spring 1993 when a great number of PSP intoxicated mackerels where detected for the first time in a wideshelf area off the Buenos Aires province. This area, known as 'El Rincón' (39°00'-40°30'S), has become a growing importance mackerel fishing ground during the last few years. A high PSP concentration was determined in those mackerels, being the... |

| This study verified the comparative histomorphometric adaptations in the stomach of rat, bat and pangolin in relation to diet. Ten rats, ten bats and ten pangolins of both sexes were used for this investigation. The animals were sacrificed after slight anesthesia under chloroform inhalation. The stomach were excised, fixed in 10% formol saline and processed for light microscopic study. Stained slides were also subjected to morphometric analysis at a magnification of 400x. The results revealed that the cellular diameter/ density of parietal and zymogenic cells are significantly different in the three mammals (p<0.05) with the exception of the diameter of the zymogenic cells in pangolin which was not statistically significant (p>0.05) when compared... |
