Liver and kidney structure and iron content in romanian brown bears (Ursus arctos) before and after hibernation.

The annual cycle of the brown bear (Ursus arctos) in the Carpathian Mountains (Romania) consists of an active period from April to November, and an inactive period (hibernation) of approximately 4-5 months between November and March. During hibernation, the brown bears sleep continually and do not feed or drink water. Analyses of liver and kidney of male brown bears showed that liver iron content was 3 times higher in bears at the end of hibernation than at the end of the active period.

Liver histological structure in adult European bison. Bison bonasus (Linnaeus, 1758).

The histological structure of the liver in 12 European bison, 2-8 years old, was presented. The study of the hepatic lobule showed that in Bison bonasus there were no connective septa around the hepatic lobules. On the hepatic lobule territory, solitary bile ducts, respectively solitary arterioles, were sometimes observed.
