A Comparative Histological Study of the Tongue of Rat (Rattus Norvegicus), Bat (Eidolon Helvum) and Pangolin (Manis Tricuspis) International Journal of Morphology
Abayomi,Taiwo A; Ofusori,David A; Ayoka,Oladele A; Odukoya,Samson A; Omotoso,Emmanuel O; Amegor,Frank O; Ajayi,Sunday A; Ojo,Gideon B; Oluwayinka,Oladele P.
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...

A Comparative Histomorphometric Study of the Stomach of Rat (Rattus norvegicus), Bat (Eidolon helvum) and Pangolin (Manis tricuspis) in Relation to Diet International Journal of Morphology
Ofusori,D. A; Caxton-Martins,E. A.
This study verified the comparative histomorphometric adaptations in the stomach of rat, bat and pangolin in relation to diet. Ten rats, ten bats and ten pangolins of both sexes were used for this investigation. The animals were sacrificed after slight anesthesia under chloroform inhalation. The stomach were excised, fixed in 10% formol saline and processed for light microscopic study. Stained slides were also subjected to morphometric analysis at a magnification of 400x. The results revealed that the cellular diameter/ density of parietal and zymogenic cells are significantly different in the three mammals (p<0.05) with the exception of the diameter of the zymogenic cells in pangolin which was not statistically significant (p>0.05) when compared...

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 &amp; E), Van Gieson and Verhoeff's...

Changes in the thyroid gland during the reproductive cycle of the male vespertilionid bat, Scotophilus heathi BJB
KRISHNA,A.; SINGH,K..
The aim of present study was to compare the changes in thyroid gland with the reproductive cycle of S. heathi. Thyroid showed marked seasonal variation in weight, quantity of colloid and follicular epithelial height, suggesting the thyroid gland to be inactive during quiescence and winter dormancy and active during the time of recrudescence and breeding similarly to the testicular cycle. Plasma thyroxin (T4) concentration showed a significant seasonal change with high concentration during breeding and post-breeding and low concentration during quiescence. However, the T4 concentration increased from breeding to post-breeding phase, when the testes weight was declining. It is suggested that in S. heathi the positive correlation between thyroid and...

Combination sensitivity and processing of communication calls in the inferior colliculus of the Moustached Bat Pteronotus parnellii Anais da ABC (AABC)
Portfors,Christine V..
Many animals use complex communication calls in social behaviors. In some species we know the features in the calls that elicit particular behaviors, but we do not understand how the auditory system encodes the calls. Nor do we understand the mechanisms underlying neural selectivity to calls. Our studies of the auditory midbrain of the Moustached Bat Pteronotus parnellii have revealed a neural mechanism important for generating selective responses to calls. Neurons that integrate information across different frequencies show selectivity to communication calls. "Combination sensitivity" may be a common mechanism for encoding complex sounds because it is also important for encoding echolocation signals.

AGUIAR, L. M. de S.; ANTONINI, Y..
Foi examinado o hábito alimentar das espécies de Vespertilionidae Myotis nigricans (Schinz, 1821) e Eptesicus furinalis (d?Orbigny, 1847) por meio de análise de amostras fecais coletadas em animais capturados em área de cerrado sensu stricto e matas de galeria, na APA ? Gama-Cabeça-de-Veado, Brasília, Distrito Federal, Brasil. Um total de 20amostras fecais foi analisado, sendo sete de E. furinalis e 13 de M. nigricans. A dieta de E. furinalis incluiu seis ordens de insetos: Coleoptera (5/7) (presença na amostra total), Lepidoptera e Hymenoptera (3/7), Diptera, Hemipterae Homoptera (1/7). A dieta de M. nigricans incluiu todas as ordens consumidas por E. furinalis (6/13, 4/13, 4/13, 3/13, 1/13, and 4/13 respectively) e uma ordem a mais: Orthoptera (1/13)....

AGUIAR, L. M. de S.; CAMARGO, W. R. de; PORTELLA, A. de S..
A espécie Diaemus youngi (Jentik, 1893) é considerada por alguns autores como ocorrendo para todo o Brasil incluindo o bioma cerrado e área rural do Distrito Federal. No entanto não há na literatura nenhum registro do local de coleta dessa espécie para essas regiões. Reportamos aqui o primeiro registro no cerrado do Brasil Central, área rural do Distrito Federal, e alguns dados sobre a biologia, conservação e distribuição geográfica da espécie no Brasil, de acordo com dados desse trabalho e da literatura.

Ultrastructural Characterization of the Pars Distalis of the Indian Female Sheath-Tailed Bat, Taphozous longimanus (Hardwicke) International Journal of Morphology
Nerkar,Archana A; Gadegone,Mohan M.
The present ultrastructural observations demonstrate the presence of six cell types in the pars distalis of non-pregnant and pregnant bats of Taphozous longimanus. In the pars distalis of T. longimanus, STH cells are round to oval with eccentrically placed nucleus, numerous secretory granules and well developed Golgi indicate a cell under vigorous synthetic activity while those filled with secretory granules with reduced Golgi complex suggest reserve or storage state of cells. LTH cell is characterized by the large secretory granules, dilated endoplasmic reticulum and numerous mitochondria in the cytoplasm which indicate that these cells are hypertrophied and synthetically very active during pregnancy. ACTH cells are found either singly or in groups and...

Ultrastructure of the Secretory Epithelial Cells of the Bulbo-Urethral Glands (Cowper's gland) in the Indian Fruit Bat, Rousettus leschenaulti (Desmarest) During the Reproductive Cycle International Journal of Morphology
Nerkar,Archana A; Gujar,Maher P; Gadegone,Mohan M.
The present paper describes the ultrastructural characteristics of the bulbo-urethral gland (Cowper' glands) of the Indian fruit bat, R. leschenaulti during sexually inactive-breeding cycle. Cyclic histological changes during the seasonal breeding quiescence cycle are not well marked. There are no marked differences. The ultrastructural characteristic of the secretory epithelial cells of Bulbo-Uretrhal Gland gland have been studied during different phases of reproductive cycle. The secretory epithelial cells are characterized by the well-developed rough endoplasmic reticulum, extensive developed complexus golgiensis (Golgi apparatus) and mitochondria. Mitochondria with lamellate cristae are dispersed in the cytoplasm. Three different types of secretory...
