| review of laboratory and necropsy evidence for iron storage disease acquired by browser rhinoceroses. | necropsies of two browser rhinoceroses, african black (diceros bicornis) and sumatran (dicerorhinus sumatrensis), often reveal extensive iron-pigment deposition in various tissues. this condition (hemosiderosis) has not been observed in species that are natural grazers, african white (ceratotherium simum) and asian greater one-horned (indian; rhinoceros unicornis), nor in any species free ranging in the wild. the causes, clinical significance, and consequences of captivity-acquired hemosiderosis ... | 2012 | 23156711 |
| iron overload syndrome in the black rhinoceros (diceros bicornis): microscopical lesions and comparison with other rhinoceros species. | the african black rhinoceros (diceros bicornis) has adapted to a low iron diet during evolution and is thus prone to iron overload in captivity, which is associated with a number of serious disorders. a s88t polymorphism in the hfe gene has been suggested as a potential genetic basis of increased iron uptake in the black rhinoceros, while the indian rhinoceros is thought to be unaffected by iron overload in captivity. in the present study, the histopathology and distribution of iron accumulation ... | 2012 | 22935088 |
| activation of southern white rhinoceros (ceratotherium simum simum) estrogen receptors by phytoestrogens: potential role in the reproductive failure of captive-born females? | the captive southern white rhinoceros (swr; ceratotherium simum simum) population serves as an important genetic reservoir critical to the conservation of this vulnerable species. unfortunately, captive populations are declining due to the poor reproductive success of captive-born females. captive female swr exhibit reproductive problems suggested to result from continual ovarian follicular activity and prolonged exposure to endogenous estrogen. however, we investigated the potential role of exo ... | 2012 | 22253418 |
| alkaline phosphatase as an indicator of true ejaculation in the rhinoceros. | the objective was to determine if seminal alkaline phosphatase (alp) can serve as an indicator of true ejaculation in the rhinoceros. concentrations of alp activity were determined in seminal fractions collected from african black rhinos (diceros bicornis), an african white rhino (ceratotherium simum), and an indian rhino (rhinoceros unicornis) during electroejaculation. in addition, seminal fractions collected during penile massage of a sumatran rhino (dicerorhinus sumatrensis) were assessed. c ... | 2010 | 20615535 |
| corticosteroid-induced suppression of in vitro lymphocyte proliferation in four captive rhinoceros species. | captive african black rhinoceroses (diceros bicornis) are unusually susceptible to several diseases not commonly observed in any of the other three rhinoceros species maintained in captivity. the potential role of corticosteroids (either endogenously produced or exogenously administered) in the development of these sometimes fatal diseases has been questioned. in this study, the suppressive effects of two therapeutic corticosteroids (dexamethasone and hydrocortisone) on in vitro lymphocyte proli ... | 2007 | 18229856 |
| semen collection in rhinoceroses (rhinoceros unicornis, diceros bicornis, ceratotherium simum) by electroejaculation with a uniquely designed probe. | electroejaculation in rhinoceroses has historically yielded inconsistent results, with the collection of high-quality, sperm-rich samples rare. the goal of this study was to develop a reliable method of electroejaculation in the rhinoceros by designing a rectal probe that appropriately fits the anatomy of this taxon and refining the procedure. a curved probe handle ending in an oblate, ellipsoid head was built using readily available supplies. a combination of rectal massage, penile massage, and ... | 2005 | 17312718 |
