AA-amyloidosis in captive northern tree shrews ().

A high prevalence of AA-amyloidosis was identified in a breeding colony of northern tree shrews () in a retrospective analysis, with amyloid deposits in different organs being found in 26/36 individuals (72%). Amyloid deposits, confirmed by Congo red staining, were detected in kidneys, intestines, skin, and lymph nodes, characteristic of systemic amyloidosis. Immunohistochemically, the deposited amyloid was intensely positive with anti-AA-antibody (clone mc4), suggesting AA-amyloidosis.

[Blood gas analysis in rabbits during a completely antagonizable anesthesia with special focus on oxygen management].

Objective: The aim of this study was to evaluate the consequences of different oxygen supplementation methods on arterial blood gas analysis during an injectable anesthesia.

Material And Methods: A total of 29 rabbits with dental diseases (tooth elongation) were sampled before, during and after coronal reduction. Oxygen was provided either via the flow-by method or with a nasal oxygen tube; the control group breathed room air.

[Gastric dilatation-volvulus syndrome in guinea pigs (Cavia porcellus)].

Aim: The aim of this study was to present an overview of the gastric dilatation-volvulus syndrome in guinea pigs.

Material And Methods: Four cases of gastric dilatation-volvulus syndrome in guinea pigs were evaluated. Its clinical presentation, diagnostic options, therapeutical approach and possible alternatives thereof were discussed.

[Oligodendroglioma with neuronal differentiation in an 8-month-old African hedgehog (Atelerix albiventris)].

An 8-month-old, male African hedgehog clinically displayed a wobbly walk, anuria, inappetence and apathy, whereupon the suspected diagnosis wobbly hedgehog syndrome was made. After exacerbation, the hedgehog was euthanized. Histologically, a tumour mainly consisting of medium-sized, oval tumour cells and a smaller number of spindeloid cells was found in the cerebrum.
