Provedor de dados: 77
Autores: Ofusori,David A; Ayoka,Abiodun O; Adeeyo,Olusola A; Adewole,Stephen O.
The aim of this study was to substitute costly and hazardous compound- xylene, used as clearing agent, with less costly compounds (mixture of xylene and kerosene) having less toxicity and without compromising the cellular integrity and staining characteristics of the sections. Tissues (liver and kidney) obtained from a presumable healthy adult Wistar rat, were fixed in 10% formol saline, separated in to five groups (A, B, C, D and E) and processed for light microscopic study adopting H &amp;amp; E staining procedure. During the clearing section, groups A, B, C, D and E were respectively cleared in solvent 1 (xylene only), solvent 2 (70ml xylene : 30ml kerosene), solvent 3 (50ml xylene : 50ml kerosene), solvent 4 (30ml xylene : 70ml kerosene) and solvent 5...

This study assessed the micro anatomical differences in the tongue of rat, bat and pangolin with a view to establishing the functional anatomical differences of these mammalian tongues on their dietary pattern. Ten rats, ten bats and ten pangolins were used for this study. The animals were sacrificed and the tongue excised and processed for light microscopical study adopting the following stains: Haematoxylin Eosin, Verhoeff Gieson and Masson trichrome. The results showed non papillation of the keratinized stratified epithelium of pangolin tongue unlike the papillation seen in the tongue of the rat and bat. While the filiform papillation seen in the rat was bristle like, the filiform papillae in the bat were crown-like. There was also an unusual dense...

Dextrocardia and Situs Inversus Totalis in a Nigerian Cadaver: A Case Report of Rare Anomaly
Provedor de dados: 77
Autores: Ofusori,David A; Okwuonu,Christina U; Ude,Raymond A; Adesanya,Olamide A.
This report describes an adult male cadaver with dextrocardia and situs inversus totalis in a Nigerian cadaver. The photographic illustrations revealed transposition of some of the visceral organs such that the stomach and spleen were located on the right and the liver and gall bladder on the left. Also, the left lung was tri-lobed while the right was uni-lobed. The heart was flattened and flipped to the right thus, transposing the great vessels. The report showed that dextrocardia and situs inversus exists amongst Nigerians and possibly Africans and therefore wish to recommend early medical examination since patients with this condition are unaware of their unusual anatomy until they seek medical attention for an unrelated condition. Early detection may...
