A Comparative Study of the Ileum in Rat (Rattus norvegicus), Bat (Eidolon helvum) and Pangolin (Manis tricuspis) as Investigated Using Histological Method International Journal of Morphology
Ofusori,D. A; Caxton-Martins,E. A; Komolafe,O. O; Oluyemi,K. A; Adeeyo,O. A; Ajayi,S. A; Oluwayinka,P. O; Adelakun,E. A; Keji,S. T; Adesanya,O. A.
The histological and morphometric differences in some parts of the gastrointestinal tracts of rat, bat and pangolin have been well established. This investigation aims at comparatively elucidating any adaptational changes the ileum of the three mammals must have adopted to meet its dietary requirements and also cope with their morphological differences. The investigation was carried out using ten rats, ten bats and ten pangolins of both sexes. The animals were slightly anaesthetized under chloroform inhalation. The intestines were harvested and the ileum excised and fixed in 10% formol saline. The tissues were processed for light microscopic study. The following stains were employed: Haematoxylin and eosin (H & E), Van Gieson and Verhoeff's...

The Ameriorating Effects of Grapefruit Seed Extract on Testicular Morphology and Function of Varicocelized Rats International Journal of Morphology
Saalu,,L. C; Udeh,R.; Oluyemi,K. A; Jewo,P. I; Fadeyibi,L. O.
Varicoceles are abnormal tortuosity and dilatation of the veins of the pampiniform plexus that drain the testis.The pathophysiology of testicular damage in varicocele has not been completely understood. However there is an increasing body of evidence pointing towards the role of reactive oxygen species and oxidative stress in the pathogenesis of varicocele related subfertility. In the present study we examined the role of proanthocynidin-rich ethanol extract of grapefruit seed as an antioxidant in protecting the testis against damage in experimental varicocele. Three groups of rats were constructed as the first group had intact rats; experimental bilateral varicoceles were established by complete ligation of the left and right main spermatic veins in the...
