Estudo morfológico dos componentes do pedículo ovariano de éguas da raça Puro Sangue Inglês

Resumo (EN)

Introduction - The main objective of this research was the micro and macroscopic analysis of the ovarian pedicle components of 15 Thoughbred adult mares, coming from the Jockey Club of São Paulo. This analysis aimed to point out the possibility of a direct transfer of luteolitic substance of the uterine veined blood to the ovarian arterial blood, which is an important fact for the reproduction process and considered possible in some species. Material and Method - Six um histological sections were examined, obtained from different segments of the ovarian pedicle, colored according to the Hematoxilin Eosin method, trichrom of Masson, Van Gieson, Verhoeff, Gomori's reticulin and Picrosirius-red. The vascular components were examined after injections of colored latex with or without contrast, Chinese ink and vinilite, followed by the dissection techniques, radiodiagnosis and corrosion. Results - The morphological characteristics of the blood vessels of ovarian pedicle, its wrappers, relationships and the components of the intervascular connective tissue were described as well as it was demonstrate the transference of substance (Chinese ink) from the uterine venous to the ovarian arterial systems. Conclusion - It was possible to register that the veined branch follows the ovarian artery, has a close and extensive relationship, and this relation shows a possibility that in this local may happen the direct transfer from the substances of the uterine veined blood to the ovarian arterial blood, the fact of which had never been observed and was even questioned regarding this species, until then.
