Salivary Gland Adenocarcinoma in a Domestic Rabbit (Oryctolagus cuniculus)

A 2.4 kg, 7-year-old, female Rex rabbit was presented with a 4-month history of a left-sided head tilt, difficulty in mastication, lethargy, and chronic wasting. Diagnostic testing of the patient revealed a severe heterophilic leukocytosis and radiographic images of the skull radiographs indicated irregularity of the left tympanic bulla. A computed tomographic scan highlighted a heterogeneously contrast-enhancing mass, ventral and rostral to the left tympanic bulla, with contrast enhancement of the meninges on the left, consistent with an aggressive neoplasm. The patient was euthanized and the mass was identified as a salivary gland adenocarcinoma. The gland of origin is suspected to be the left parotid, owing to its location and close association with normal parotid tissue. To the authors' knowledge, this is the first report of a salivary gland adenocarcinoma in a domestic rabbit. A computed tomography (CT) scan and histopathology examination were useful modalities for identifying the neoplasm in this case.

Nutritive value evaluated on rats of new cultivars of common beans (Phaseolus vulgaris) released in Chile

Five new cultivars of common beans (Phaseolus vulgaris) recently released were analyzed for their proximate chemical composition and protein biological quality. The crude protein content in these cultivars ranged from 21.9 percent in cultivar Arroz 3 to 26.9 percent in cultivar Tórtola Diana (dry matter basis). Rats fed cultivar Tórtola INIA gained more weight, had a higher protein intake and registered higher PER and NPR than Tórtola corriente. On the other hand, rats consuming cultivars Arroz 3 and Fleetwood had lower weight gain, lower protein intake and lower PER and NPR than cultivar Coscorrón corriente. However, all these cultivars have a relatively good protein value as compared to other plant protein sources.
