Trophic relationships gonad-intestinal loop in Pecten maximus .
Provedor de dados: 5
Autores: Lepennec, M; Dorange, G; Beninger, P; Donval, A; Widowati, I.
Histological, histochemical and ultrastructural studies were performed on the region of the gonad traversed by the intestine in Pecten maximus . The results indicate a digestive and absorptive function of intestine epithelial cells and a transfer of metabolites to the surrounding gonad tissue. Several possible mechanisms of translocation are presented, including diffusion into the haemolymph and transfer via vacuolated cells of the gonad interstitial connective tissue.

Adaptations biochimiques intestinales chez la truite: Influence de l'aliment et de la salinite sur quelques proprietes membranaires
Provedor de dados: 5
Autores: Leray, C.
The authors report the results of physiological and biochemical experiments which confirm the important role player by fish (Salmo gairdneri ) intestinal mucosa in their osmoregulatory process. The ability of the dietary lipids to modulate this function is described. It was demonstrated that the ionic apical permeability of the enterocytes are related to their membrane lipid composition. The importance of the essential fatty acids is emphasized. The time course changes of the apical permeability are of value in improving sea water adaptation, similar conclusions are reported for Nacl supplementation.

L'absorption intestinale des lipides chez la truite arc-en-ciel (Salmo gairdneri )
Provedor de dados: 5
Autores: Vernier, J; Sire, M.
Though the absorption of dietary lipids is much slower in S. gairdneri than in mammals, the mechanism does not differ fundamentally. The long chain fatty acids resulting from intraluminal hydrolysis are esterified by the epithelial cells and transferred as VLDL-like particles and chylomicrons to lymph. The size of granules depends on the nature of the ingested fatty acids. The intracellular stages of this lipoprotein synthesis are defined.

Comparative Intestinal Histomorphology of Five Species of Phyllostomid Bats (Phyllostomidae, Microchiroptera): Ecomorphological Relations with Alimentary Habits
Provedor de dados: 77
Autores: Gadelha-Alves,Rafaela; Rozensztranch,Andréa Melo Da Silva; Rocha- Barbosa,Oscar.
The intestines of Sturnira lilium, Phyllostomus hastatus, Carolliaperspicillata, GlossophagasoricinaíindDesmodus rotundus were analized through macroscopic, morphometric and light microscopy studies. The species studied presented some common charactenstics generally found in bats, such as the absence of a caecum and an appendix. The frugivorous bat S. lilium has a longer intestine than the other species. The intestinal epithelium is of the simple columnar type, constituted of absorptive cells characterized by microvilli and goblet cells, which in all the species proved to be PAS + and AB +. These cells presented some differences in quantity and in distribution among the species. The intestinal mucosa presented morphologic and morphometric differences, such...
