Resumo: | The goal of this research was to determine the volumetric proportions of the structural components of the goat placenta throughout gestation. We used nine goats of nondefined breed, separated into groups A, B and C, with 90, 120 and 150 days of gestation, respectively. From each animal fragments of three placentomes were obtained, one removed from the base, another from the middle part and the other from the end of the gestational uterine horn. The fragments were fixed in Bouin solution and histologically processed according to the standard techniques and stained with hematoxilin-eosin. Microscopically, a 25-point circular grid (Zeiss KPL ocular 6.3x with 25 points) was randomly used across the placentome to determine the volumetric proportion of the maternal and fetal connective tissue, syncytium, trophoblastic epithelium and binucleate cells. An increase of volumetric proportion of the syncytium was found at the end of gestation and also a decrease of volumetric proportion of fetal connective tissue in the same period. |

Foram utilizadas nove cabras adultas sem raça definida, separadas em grupos A, B e C, com 90, 120 e 150 dias de gestação, respectivamente. De cada animal foram colhidos fragmentos de três placentomas, sendo um localizado na base do corno uterino, outro no terço médio e o último da extremidade. Os fragmentos foram fixados em solução de Bouin, processados segundo as técnicas rotineiras de inclusão em parafina e corados pela hematoxilina e eosina. Microscopicamente, uma ocular integradora (Ocular Zeiss KPL 6,3x com 25 pontos) foi aleatoriamente sobreposta sobre a secção do placentoma para a determinação da proporção volumétrica do tecido conjuntivo materno e fetal, do sincício, do epitélio trofoblástico e das células binucleadas. Foi observado aumento na proporção volumétrica do sincício ao final da gestação e diminuição do tecido conjuntivo fetal no mesmo período.Universidade de São Paulo.
