Methallibure studies on Tilapia: II. Effect of tilapia pituitary homogenate (TPH), human chorionic gonadotropin (HCG) and testosterone propionate (TP) on the testes of Methallibure-treated Tilapia nigra
(University of Nairobi, 1974-07)
In Methallibure-suppressed T. nigra testes high and low doses of TPH and HCG stimulate a qualitatively similar reactivation of spermatogenesis resulting in a significant elevation of testicular weight and G.S.I.; interstitial ...
Effect of chorionic gonadotrophin on testicular histology and testosterone production in Tilapia leucosticta (Teleostei: Cichlidae
(University of Nairobi, 1970-10)
Eight adult male T. leucosticta were given daily injections of 500 IU human chorionic gonadotrophin (Pregnyl, Organon) intraperitoneally for 1 week. These fish showed marked increases in testicular size, gonosomatic index, ...

Methallibure studies on tilapia. III. Effects of tilapian partially purified pituitary gonadotrophic fractions on the testes of Methallibure-treated Sarotherodon spirulus (= Tilapia nigra)
(University of Nairobi, 1979-12)
Tilapian fish Sarotherodon spirulus (= Tilapia nigra) were treated with the gonadotrophic inhibitor, methallibure, for 9 weeks during the last 2 of which they were divided into a control group and 8 experimental groups. ...

(University of Nairobi, 1975-01)
The comparison of certain proportions of lumbar vertebral bodies and of the lumbar column as a whole between a range of primate and non-primate mammals suggests that the relatively high robusticity of the lumbar column in ...
