Changes in thyroxine, triiodothyronine and metabolic rate in the dik-dik antelope (Rhynchotragus kirkii): effects of temperature and dehydration
(University of Nairobi, 1983-02)
Changes in plasma total thyroxine, triiodothyronine (T3) and metabolic rate were investigated in both hydrated and dehydrated dik-diks after prolonged exposure to ambient..

An ultrastructural and histochemical study of the axial musculature in the African lungfish.
(Springer-Verlag., 1981)
Red, intermediate, and white axial muscle fibres of African lungfish were studied using histochemical techniques and electron microscopy. Gross dissection revealed the presence of a small wedge of red coloured muscle along ...
Colonic absorption and secretion of electrolytes as seen in five species of East African herbivorous mammals
(University of Nairobi, 1980)
1. The camel, sheep, goat and donkey were equally efficient in recovering fluids from colonic contents. Zebu cattle were the least efficient.
2. Compared to other species, Zebu cattle demonstrated a reduced sodium and ...
Cyclic changes in the osmolality and electrolyte composition in the gastrointestinal tract of the rock hyrax.
(1978-06)
The rock hyrax has been shown to have a very unusual
and complex digestive tract. The gastrointestinal tract is comparable to
that of the simple and complex stomach of mammals as well as to that of
birds. Determinations ...
Gastrointestinal osmolality electrolyte and organic acid composition in five species of East African herbivorous mammals.
(1980-10)
Inherent differences observed in ionic
composition of gastrointestinal contents due to
diet, feeding regimen and (or) site along the
length of the digestive tract were controlled so
that a clearer understanding of ...
Na+ AND Cl~ EFFLUXES AND IONIC REGULATION IN TILAPIA GRAHAMI, A FISH LIVING IN CONDITIONS OF EXTREME ALKALINITY
(1981)
The osmoregularity ability of the cichlid Tilapia grahami enables this fish to live
in conditions of extreme alkalinity (Reite, Maloiy & Aashaug, 1974; Maloiy et al.
1978). In this paper we describe the ionic balance of ...
Aquatic and Aerial Respiration Rates, Muscle Capillary Supply and Mitochondrial Volume Density in the Airbreathing Catfish (Clarias Mossambigus) Acclimated to Either Aerated or Hypoxic Water
(1983)
Specimens of the African air-breathing catfish Clarias mossambicus were acclimated to either aerated (PwO2 15.3 KPa) or hypoxic (PwO2 2.4KPa) water for up to 27 days at 20 °C. Routine respiration rate for fish acclimated ...
Digestive secretions in camels
(University of Nairobi, 1989)
The digestive secretions of both old world and new world camels are considered
The salivary glands closely resemble those of cattle and sheep both morphologically andphysiologically. Evidently, as in the Ruminantia, ...
The Morphometry of the Lung of the African Lungfish (Protopterus aethiopicus): Its Structural--Functional Correlations
(1985)
The lung of the African lungfish Protopterus aethiopicus has been investigated by morphometric techniques. The volume of the lung was strongly correlated with body mass. The exchange tissue made up about 50% of the lung. ...
