Zusammenfassung: | Abstract The aim of this study was to determine the endothelial cell morphology in the different regions of healthy bovine corneal endothelium using optical microscopy. Twenty eyeballs from 10 male Brangus cattle, aged 24 months, were studied. The corneal endothelium was stained with the vital dye alizarin red and then examined with an optical microscope and photographed. Thirty endothelial cells from each corneal region were included in the analysis. Endothelial cell morphology was analysed in the central, superior, inferior, lateral and medial regions of the cornea. Comparisons between regions were performed using repeated measures analysis of variance (ANOVA). Differences were considered statistically significant at P < 0.05. Normal endothelial cells were mainly hexagonal (83.7%), pentagonal (7.45%) and heptagonal (8.8%), with a minimal number of cells of other shapes present. No statistical differences were observed in the endothelial cell morphology when comparing different regions of the cornea. Regarding endothelial cell morphology, there were no differences between the corneal regions.
Resumo O objetivo deste estudo foi determinar a morfologia das células endoteliais nas diferentes regiões do endotélio da córnea bovina saudável por meio de microscopia óptica. Foram estudados 20 globos oculares de 10 bovinos machos da raça Brangus, com idade de 24 meses. O endotélio da córnea foi corado com o corante vital vermelho de alizarina e, em seguida, examinado no microscópio óptico e fotografado. Trinta células endoteliais de cada região da córnea foram incluídas na análise. A morfologia das células endoteliais foi analisada nas regiões central, superior, inferior, lateral e medial da córnea. As comparações entre as regiões foram realizadas usando medidas repetidas de análise de variância (ANOVA). As diferenças foram consideradas estatisticamente significativas em P < 0,05. As células endoteliais normais eram principalmente hexagonais (83,7%), pentagonais (7,45%) e heptagonais (8,8%), com um número mínimo de células de outras formas presentes. Não foram observadas diferenças estatísticas na morfologia das células endoteliais quando comparadas as diferentes regiões da córnea. Em relação à morfologia das células endoteliais não houve diferenças entre as regiões da córnea estudadas. |
