Qualitative and quantitative variations of the vaginal epithelium in Myocastor coypus bonariensis (coypu) during the estrous cycle

The aim of the present study was to characterize the qualitative and quantitative changes in the vaginal\nepithelium in the coypu (M. c. bonariensis) during the estrous cycle. A daily colpocytological evaluation\nwas performed in 36 females. Samples from three vaginal sections (cephalic, middle and...

spelling I28-R145-HWA_70892023-06-15 The aim of the present study was to characterize the qualitative and quantitative changes in the vaginal\nepithelium in the coypu (M. c. bonariensis) during the estrous cycle. A daily colpocytological evaluation\nwas performed in 36 females. Samples from three vaginal sections (cephalic, middle and caudal) were\nprocessed with routine histological techniques. The mean cycle duration was of 36.86 ± 10.52 days. The\ngreater thickness of the epithelium was observed in the proestrous and the smallest in the metestrous.\nVariations in epithelial thickness in each cycle stage for the different sampled regions showed nonsignificant differences in the estrous and proestrous. Differences were observed during the metestrous between the cephalic and middle and middle and caudal regions, and also during the diestrous, being the most significant between cephalic and middle regions. At metestrous, a significant decrease in the number of epithelial layers was observed in all the regions. At diestrous, differences were observed between cephalic and middle, and cephalic and caudal regions.\n Fil: Felipe, A.E. Universidad Nacional del Centro de la Provincia de Buenos Aires.

Lombardo, D.M. 2022 El objetivo del presente estudio fue caracterizar los cambios cualitativos y cuantitativos en el epitelio vaginal del coipo (M. c. Bonariensis) durante el ciclo estral. Se realizó una evaluación colpocitológica diaria en 36 hembras. Las muestras de tres zonas vaginales (cefálica, media y caudal) se procesaron con técnicas histológicas de rutina. La duración media del ciclo fue de 36,86 ± 10,52 días. El mayor grosor del epitelio se observó en el proestro y el menor en el metaestro. Las variaciones en el espesor epitelial en cada etapa del ciclo para las diferentes regiones muestreadas no mostraron diferencias significativas en estro y proestro. Se observaron diferencias durante el metaestro entre las regiones cefálica y media y media y caudal, y también durante el diestro, siendo las más significativas entre las regiones cefálica y media. En el metaestro, se observó una disminución significativa en el número de capas epiteliales en todas las regiones. En el diestro se observaron diferencias entre las regiones cefálica y media y cefálica y caudal. application/pdf ISSN 1668-3498 (en línea) coipo Myocastor coypus roedores histricognatos vagina ciclo estral coypu Myocastor coypus hystricognath rodents vagina estrous cycle eng Universidad de Buenos Aires.
