Resumo: | Morphological characterization of the intercaruncular region of pregnant cows and water buffalo cows. Intercaruncular glandular regions were found among the uterine caruncles in ruminant pregnant uteruses. The endometrial glands play an important role in the substance transfer from dam to fetus, including that of iron. Therefore, our objective was to characterize these intercaruncular regions of the pregnant uterus of zebu and buffalo cows. Small portions of the same regions of zebu (n=57) and water buffalo cows (n=30) were fixed in 10% formaldehyde and 4% paraformoldehyde in PBS, processed and stained for light microscopy in order to characterize the morphology, and histochemistry (Perl’s, PAS and acid phosphatase reactions) to confirm iron transfer. The intercaruncular region was located among the uterine caruncles and was composed by an endometrium, a myometrium, and a richly vascularized perimetrium. The endometrial glands were made up of a simple columnar epithelium and they were reactive to ferric iron (Perl's reaction), acid phosphatase and PAS. Collectively, the present results support the hypothesis that endometrial glands are important sites of secretion and substance transfer from the dam and that they are implicated in the nourishment of the ruminant fetus. |

As glândulas endometriais desempenham importante função de transferência de substâncias da mãe para o feto, incluindo o ferro. Sendo assim, tivemos por objetivo caracterizar estas regiões intercarunculares do útero gestante de vacas zebuínas e búfalas. Amostras destas mesmas regiões de vacas zebuínas (n=57) e búfalas (n=30), em vários estágios de gestação, foram fixadas em solução aquosa de formaldeído a 10% e paraformaldeído a 4% em PBS, processadas e coradas para microscopia de luz, para caracterizar a morfologia e histoquímica (reações de Perl's, PAS e fosfatase ácida), para confirmar a transferência de ferro. A região intercaruncular situou-se entre as carúnculas uterinas e foi composta pelo endométrio, miométrio e perimétrio altamente vascularizado. As glândulas endometriais eram constituídas por epitélio prismático simples e reagiram positivamente ao ferro férrico (reação de Perl’s), à enzima fosfatase ácida e à reação do PAS. Analisados conjuntamente, os presentes resultados sustentam a hipótese de que as glândulas endometriais são sítios importantes de secreção e transferência de substâncias da mãe, implicadas na nutrição histiotrófica dos fetos de ruminantes, principalmente as proteínas que agem como enzimas, carreadores de moléculas para hormônios, vitaminas e minerais e como moléculas sinalizadoras do reconhecimento da gestação.Universidade Federal de Santa Catarina2007-01-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://periodicos.ufsc.br/index.php/biotemas/article/view/20677Biotemas; v. 20 n. 3 (2007); 103-1142175-79250103-1643reponame:Biotemas (Online)instname:Universidade Federal de Santa Catarina (UFSC)instacron:UFSCporhttps://periodicos.ufsc.br/index.php/biotemas/article/view/20677/18833Copyright (c) 2007 Rodrigo da Silva Marques, Mirella Vulcano, Susana M.
