PHEOCHROMOCYTOMA IN AN AGED FEMALE AFRICAN ELEPHANT (LOXODONTA AFRICANA)

Journal of Zoo and Wildlife Medicine, 2005
A 43 yr-old female African elephant (Loxodonta africana) collapsed acutely and died. Necropsy revealed an enlarged right adrenal medulla. Histologic appearance was typical of pheochromocytoma. Special stains and electron microscopy demonstrated chromaffin granules, suggesting that the tumor was derived from catecholamine secreting cells of the adrenal ...

AbstractResearch on vocal communication in African elephants has increased in recent years, both in the wild and in captivity, providing an opportunity to present a comprehensive review of research related to their vocal behavior. Current data indicate that the vocal repertoire consists of perhaps nine acoustically distinct call types, “rumbles” being ...

Hyperprolactinemia is not associated with hyperestrogenism in noncycling African elephants (Loxodonta africana)

General and Comparative Endocrinology, 2013
African elephants in US zoos are not reproducing at replacement levels. This is in part due to physiological problems, one of which is abnormal ovarian cyclicity that has been linked to increased prolactin secretion (hyperprolactinemia). A relationship between increased estrogen production (hyperestrogenism) and hyperprolactinemia has been found in ...

The fluidity of blood in African elephants (Loxodonta africana).

Clinical hemorheology and microcirculation, 2006
The large cellular volume of erythrocytes and the increased plasma concentration of proteins in elephants are factors which potentially affect blood rheology adversely. To verify blood rheology, routine hemorheologic variables were analyzed in four African elephants (Loxodonta africana), housed in the zoo of Vienna.
