Ultrastructure of the chorioallantoic placenta of the springhare (Pedetes capensis larvalis Hollister)
(1985)
The ultrastructure of the springhare placenta (Pedetes capensis larvalis) has been described. The interhemal membrane consists of the fetal capillary endothelium, syncytial trophoblast and maternal capillary endothelium ...
The influence of cobalt/vitamin B12 deficiency as a "stressor" affecting adrenal cortex and ovarian activities in goats.
(University of Nairobi., 1984)
Twenty 1.5 to 2-year old goats were made vitamin B12 deficient by feeding them cobalt-deficient diets for 23 weeks in order to determine the effects of a progressive deficiency on ovarian and adrenal cortex activities. At ...
Trypanosome-induced depression of plasma thyroxine. Levels in prepubertal and adult female goats.
(University of Nairobi., 1988-09)
Changes in plasma T4 levels were investigated in prepubertal and adult female goats during the course of an experimental Trypanosoma congolense infection. A significant decline in the T4 levels was observed within 1 week ...
Plasma vitamin B12 and reproductive performance of cows on cobalt-deficient pastures in the Rift Valley of Kenya.
(University of Nairobi., 1980)
Plasma vitamin B12 and glucose in beef and dairy cattle were determined in a well-managed and poorly-managed farm in the cobalt-deficient pastures of the Naivasha area of the Rift Valley of Kenya. These values were compared ...
Effects of cobalt deficiency on the ovarian function in the East African short-horned goat.
(University of Nairobi., 1985)
24 normocyclic East African short-horned goats were made vitamin B12-deficient through feeding cobalt-deficient Rhodes grass (Chloris gayana) hay. The deficiency was confirmed by controls of the blood level, by the occurrence ...

Effect of African trypanosomiasis on plasma cortisol and thyroxine concentration in goats.
(University of Nairobi., 1989-11)
Changes in plasma cortisol and thyroxine (T4) levels were measured weekly in female goats experimentally infected with Trypanosoma congolense. Values for plasma cortisol (range 10 to 25 nmol litre-1) and T4 (range 65 to ...
Electron microscopic study of the chorioallantoic placenta of the rock hyrax (Heterohyrax brucei).
(University of Nairobi., 1983-07)
The interhaemal membrane consisted of only two cellular elements: a single layer of cellular trophoblast and the fetal capillary endothelium. The hyrax is therefore one of the few mammals known to possess the cellular ...
The placenta and fetal membranes of the short-nosed elephant shrew, Elephantulus rufescens (Peters, 1878)
(University of Nairobi,, 1980)
Trypanosome-induced increase in prostaglandin F< sub> 2α</sub> and its relationship with corpus luteum function in the goa
(1989)
Plasma progesterone and 13,14-dihydro-15-keto Prostaglandin F2α (PGFM) were measured in normal (uninfected) and -infected adult goats for a period of 121 d, from May to August, during the breeding season in Kenya. Chronic ...
