A scanning electron microscope study of the pecten oculi of the black kite (Milvus migrans): possible involvement of melanosomes in protecting the pecten against damage by ultraviolet light.

Kiama, S G, Bhattacharjee, J, Maina, J N, Weyrauch, K D

The pecten oculi of the black kite (Milvus migrans), a diurnally active bird of prey, has been examined by scanning electron microscopy. In this species the pecten consists of 12 highly vascularised...

Stereological methods for estimating the functional surfaces of the chiropteran small intestine.

Makanya, A N, Mayhew, T M, Maina, J N

A tissue sampling protocol has been devised for studying the functional surfaces of chiropteran small intestine and drawing comparisons within and between species. The goal was to obtain minimally...

A morphometric analysis of chloride cells in the gills of the teleosts Oreochromis alcalicus and Oreochromis niloticus and a description of presumptive urea-excreting cells in O. alcalicus.

Maina, J N

The gills of Oreochromis alcalicus, a hyperosmotic and low pH adapted teleost, and Oreochromis niloticus, a freshwater closely related fish have been investigated by transmission electron microscopy...

The lung of the emu, Dromaius novaehollandiae: a microscopic and morphometric study.

Maina, J N, King, A S

Qualitative and quantitative characteristics suggest that the lung of the emu is poorly adapted for gas exchange when compared with that of other birds. The granular epithelial cells extend over the...

The morphology of the lung of the black mamba Dendroaspis polylepis (Reptilia: Ophidia: Elapidae). A scanning and transmission electron microscopic study.

Maina, J N

The lung of a snake, the black mamba (Dendroaspis polylepis), has been investigated by scanning and transmission electron microscopy. This species has only one lung, the right, which is long and...

A morphological and morphometric study of the prosimian lung: the lesser bushbaby Galago senegalensis.

Maina, J N

The lung of the lesser bushbaby (Galago senegalensis) has been investigated morphologically and morphometrically using the transmission and scanning electron microscopes. Grossly and microscopically,...

The morphology and morphometry of the adult normal baboon lung (Papio anubis).

Maina, J N

The gross, histological and ultrastructural organisation of the baboon lung was found to be similar to that of the human lung. It is suggested that, in general, the lungs of the non-human primates...

Expression of fibroblast growth factor-2 (FGF-2) in early stages (days 3–11) of the development of the avian lung, Gallus gallus variant domesticus: an immunocytochemical study

Maina, J N, Madan, A K, Alison, B

In the avian lung, the bronchial system forms from epithelial (endodermal) cells. The intrapulmonary primary bronchus is the focal point of airway development. It originates secondary bronchi (SB)...

Ultrastructural characterization of the pulmonary cellular defences in the lung of a bird, the rock dove, Columba livia

Maina, J. N., Cowley, H. M.

Free (surface) avian respiratory macrophages (FARMs) were harvested by lavage of the lung/air-sac system of the rock dove, Columba livia. The presence of FARMs in the atria and infundibula was...
