MORPHOMETRIC ANALYSIS OF THE DEVELOPMENT OF THE OVARIAN FOLLICLES IN PINEALECTOMIZED RATS International Journal of Morphology
Pereira dos Santos,Katharine Raquel; Coelho Teixeira,Álvaro Aguiar; da Silva Neto,Eulâmpio José; Teixeira,Valéria Wanderley; da Cunha,Franklin Magliano.
The present study had the objective of analyzing morphometrically the occupied area by the ovarian follicles in ovaries of pinealectomized female rats. To do so, 24 albino female rats (Rattus norvegicus albinus) were used, which were equally divided in the following groups: Group I ­ sham-pinealectomized rats and kept in the light/dark cycle (12/12 hours), for three months; Group II ­ pinealectomized rats and kept in the light/dark cycle (12/12 hours), for three months; Group III ­ pinealectomized rats and kept in the absence of light for three months; Group IV ­ sham-pinealectomized rats and kept in the absence of rats for three months. The results showed that the groups I and IV presented, respectively, average of 19,00 and 25,00, while groups II and III...

EVALUATION OF THE IMPLANTATION IN PINEALECTOMIZED AND/OR SUBMITTED TO THE CONSTANT ILLUMINATION RATS International Journal of Morphology
Coelho Teixeira,Álvaro Aguiar; Simões,Manuel de Jesus; Wanderley Teixeira,Valéria; Soares Júnior,José Maria.
In this paper we evaluated the morphologic and quantitative aspects of the implantations sites in uteruses of female pinealectomized and/or submitted to the constant illumination rats. The experimental groups were: I - normal female rats maintained in a clear/dark cycle of 12/12 hours, for two months, mated and euthanasiated in the 6th day of pregnancy (control); II - female sham-pinealectomized rats maintained in a clear/dark cycle of 12/12 hours, for two months, mated and euthanasiated in the 6th day of pregnancy (control); III - female pinealectomized rats, maintained in a clear/dark cycle of 12/12 hours, for two months, mated and euthanasiated in the 6th day of pregnancy; IV - normal female rats maintained in constant illumination for two months, mated...
