Resumo: The aim of this work was study endocrine pancreas of bats with different feeding habits (hemataphagous D. ecaudata, nectarivorous A. Geoffroyi and insetivorous P. personatus) by histological, morphometric and stereological methods. Six animals was used in each group and they were collected in the caverna casa de Pedra (Sergipe). The pancreas was processed through routine histological techniques for paraffin embedding. Histologically, components of the exocrine pancreas (acini and their secretory ducts associated) and endocrine pancreas (pancreatic islet) were identified. Immunoreactive cells (IR) to insulin, glucagon and somatostatin were found isolated scattered in the exocrine pancreas and, in the tissue near the pancreatic ducts. It was also identified IR cells to insulin, glucagon and somatostatin. In the pancreatic islets, it was to indentifided cells with cytoplasmic processes. The total mass of pancreatic tissue in body weight does not exceed 0.6% and this relationship was higher in the insectivorous bats (0.6%) and lowest in nectarivorous bats (0.3%). The pancreatic islets diameter varied between species, being 88.16 ?m in the nectararivorous bat, in the vampire bat at 56.94 ?m and 40.47 ?m in the insectivorous bat. The stereological analysis showed a volume density (Vv) of the endocrine pancreas of 3.4% in the insectivorous bat, 6.1% in the nectarivorous bat and 4.1%. in the vampire bat. The islet mass was 0.15 in the insectivorous bat, 0.24 in the nectarivorous bat and 0.48 in the vampire bat. The volume density of ? cells was (25.8%, 14.7, 16.2%), ? cells (35.5%, 8.7%, 54.8%) and ? cells (3.9 %, 6.2%, 14.3%) in the P. personatus, A. geoffroyi and D. ecaudata bats, respectively. The differences observed between species in the various parameters analyzed may reflect inter-specific differences, as well as morphological adaptations of species to their eating habits.

Foram utilizados ao todo seis animais de cada grupo, coletados na caverna casa de Pedra (Sergipe). O p?ncreas foi processado atrav?s das t?cnicas histol?gicas de rotina para inclus?o em parafina. Histologicamente, foram identificado os componentes ex?crinos (?cinos secretores e seus ductos associados) e end?crinos (ilhotas pancre?ticas) do p?ncreas. Foram observadas c?lulas imunoreativas (IR) ? insulina, glucagon e somatostatina espalhadas isoladamente no p?ncreas ex?crino e, na regi?o de tecido conjuntivo pr?ximo aos ductos pancre?ticos, foram identificadas c?lulas IR ? insulina, glucagon e somatostatina. C?lulas com a presen?a de processos citoplasm?ticos foram visualizadas nas ilhotas. A massa de tecido pancre?tico total sobre a massa corporal n?o ultrapassa a rela??o de 0,6%, sendo esta rela??o maior nos morcegos inset?voros (0,6%) e menor nos morcegos nectar?voros (0,3%). O di?metro das ilhotas variou entre as esp?cies sendo de 88,16 ?m no morcego nectar?voro, de 56,94 ?m no morcego hemat?fago e de 40,47 ?m no morcego inset?voro. A an?lise estereol?gica mostrou uma densidade de volume (Vv) do p?ncreas end?crino de 3,4% no morcego inset?voro, 6,1% no morcego nectar?voro e de 4,1% no morcego hemat?fago. A massa das ilhotas foi de 0,15 no morcego inset?voro, 0,24 no morcego nectar?voro e 0,48 no morcego hemat?fago. A densidade de volume das c?lulas ? foi de (25,8%, 14,7, 16,2%), c?lulas ? (35,5%, 8,7%, 54,8%) e c?lulas ? (3,9%, 6,2%, 14,3%) nos morcegos P. personatus, A. geoffroyi e D. ecaudata, respectivamente. As diferen?as observadas entre esp?cies nos diversos par?metros analisados podem refletir diferen?as inter-espec?ficas, assim como adapta??es morfol?gicas das esp?cies ao seus h?bitos alimentaresSubmitted by Sandra Pereira (srpereira@ufrrj.br) on 2020-10-21T13:21:01Z No. of bitstreams: 1 2011 - Clarice Machado dos Santos.pdf: 1877332 bytes, checksum: 3627f6c2c3ce8cc4818df6d550417232 (MD5)Made available in DSpace on 2020-10-21T13:21:01Z (GMT).

description The aim of this work was study endocrine pancreas of bats with different feeding habits (hemataphagous D. ecaudata, nectarivorous A. Geoffroyi and insetivorous P. personatus) by histological, morphometric and stereological methods. Six animals was used in each group and they were collected in the caverna casa de Pedra (Sergipe). The pancreas was processed through routine histological techniques for paraffin embedding. Histologically, components of the exocrine pancreas (acini and their secretory ducts associated) and endocrine pancreas (pancreatic islet) were identified. Immunoreactive cells (IR) to insulin, glucagon and somatostatin were found isolated scattered in the exocrine pancreas and, in the tissue near the pancreatic ducts. It was also identified IR cells to insulin, glucagon and somatostatin. In the pancreatic islets, it was to indentifided cells with cytoplasmic processes. The total mass of pancreatic tissue in body weight does not exceed 0.6% and this relationship was higher in the insectivorous bats (0.6%) and lowest in nectarivorous bats (0.3%). The pancreatic islets diameter varied between species, being 88.16 ?m in the nectararivorous bat, in the vampire bat at 56.94 ?m and 40.47 ?m in the insectivorous bat. The stereological analysis showed a volume density (Vv) of the endocrine pancreas of 3.4% in the insectivorous bat, 6.1% in the nectarivorous bat and 4.1%. in the vampire bat. The islet mass was 0.15 in the insectivorous bat, 0.24 in the nectarivorous bat and 0.48 in the vampire bat. The volume density of ? cells was (25.8%, 14.7, 16.2%), ? cells (35.5%, 8.7%, 54.8%) and ? cells (3.9 %, 6.2%, 14.3%) in the P. personatus, A. geoffroyi and D. ecaudata bats, respectively. The differences observed between species in the various parameters analyzed may reflect inter-specific differences, as well as morphological adaptations of species to their eating habits.
