摘要
Morphology of the uterus and mammary glands were studied in sexually matured female African giant rat. The uterus was identified as being duplex, having two separate uterine horns and two cervices. The two cervices were partially fused and separated by a mid-saggital septum. Their thick musculatures projected caudally into the vagina as the portio vaginalis uteri. The results also showed that eight mammary glands, distributed along the lateral aspects of thoracic and inguinal regions, were present. The thoracic and the inguinal regions had four mammary glands each and were arranged in two pairs of cranial and caudal rows. These findings fill some gaps created by the dearth of information on the reproductive biology of the female African giant rat. La morfolog赤a del 迆tero y las gl芍ndulas mamarias fueron estudiadas en ratas Africanas gigantes sexualmente maduras. El 迆tero fue identificado como doble, teniendo dos cuernos uterinos separados y dos cervix. Los dos cervix estaban parcialmente fusionados y separados por un tabique mediano sagital. Su grosor muscular se proyecta caudalmente en la vagina como la porci車n vaginal del cuello uterino. Los resultados tambi谷n mostraron que ocho gl芍ndulas mamarias, distribuidas a lo largo de las zonas laterales de t車rax y la regi車n inguinal estaban presentes. La regi車n tor芍cica e inguinal ten赤a cuatro gl芍ndulas mamarias en cada lado y se organizaron en dos pares de filas craneales y caudales. Estos hallazgos completan algunas lagunas creadas por la escasez de informaci車n sobre la biolog赤a reproductiva de la rata gigante Africana hembra.
