| 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 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... |

| 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... |

| Fifty male and fifty female Spargue-Dawley rats were randomly chosen and used to study the sexual dimorphisms of stomachic histological structures. The rat stomach consisted of the nonglandular part and the glandular part. The gender differences of the nonglandular part existed in the thicknesses of the stratified squamous epithelium and the longitudinal muscle. These findings revealed that the male rat stomach may storage more foods than the female. The gastric glands occupied all the lamina propria in the glandular part. The thicknesses of the gastric glands of the female and male rat were 525.0 ± 95.9 µm and 472.0 ± 158.7 µm respectively, and the difference was very significant (p<0.01). The gastric glands could be divided to two layers in the HE... |

| The pirarucu, Arapaimidae family fish, is one of the most important and emblematic species of Amazon. To investigate their circulatory system anatomies features were used 10 specimens with 74 cm medium total length, from river Araguaia lakes, Sao Miguel do Araguaia, Goias, Brazil. The fishes had their celomatic cavity open with dorsal aorta artery identified and cannulation where was injected synthetic latex. Fixation of those specimens was by injection of 10% formalin. In that specie, the coeliac-mesenteric artery is the only one arterial vessel responsible to digestive tract flow and always ramified from 2nd, 3rd and 4th left efferent branchial arteries. The stomach is flowing by coeliac artery and a gastric branch of the cecal ventral artery; intestine... |

| 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... |

| The ontogenesis of the gastroesophageal mucosa involves morphological alterations related to its structure and the function of each segment. The present study describes the histogenesis of the mucus-secreting epithelium and glands of the esophagus, gizzard, and proventriculus of the chicken (Gallus gallus), and identifies alterations in the secretion pattern of glycosaminoglycans (GAG's). We analyzed 38 chicken embryos, processed the material collected following the histological routine, and then stained it with hematoxylin-eosin for the analysis of tissue structure and with Gomori's trichrome for the identification of conjunctive tissue and collagen fibers. We used the PAS histochemical technique for the analysis of neutral GAG's and the AB pH 2.5... |

| The microstructure of oesophagus and stomach in grey-backed shrike were examined by means of light microscopy. The results showed that the oesophagus glands were mucous glands, the shedding glandular cells and the mucin from the oesophagus glands secreted to the lumen. The number of the glands in the thoracic part was less than that of in the cervical part. The lumens of the glands showed an intense positive periodic acid-Schiff and Alcian blue reaction. There were two types of glands in the lamina propria. The simple tubular glands were located in the superficial lamella of the lamina propria, while compound tubular glands were located in the deep lamella. The epithelium was lined by a layer of cuticle in the intermediate zone between the proventriculus... |

| 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 macroscopic anatomy and vascularization of the stomach compartments of Bradypus torquatus were examined in five animals from the University of São Paulo College of Veterinary Medicine and Zootechny collection. The method included aqueous perfusion of the arterial network, colored latex injection, fixation in formaldehyde (10%) and preservation in Laskovisk solution. Dissections were performed under mesoscopic light and photo documentations were performed for description and data analysis. In these animals, the largest abdominal organ was the stomach, which internally presented the cardiac, fundic and prepyloric regions, subdivided in six compartments (cardiac right, middle and left; fundic; pre-pyloric I and II). The stomach was irrigated by the left... |

| 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... |

| 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.... |
