Antioxidant Activity of Different Hop ( L.) Genotypes.

The antioxidant activity (AA) of hop extracts obtained from different hop genotypes ( = 14) was studied. For comparison, the purified β-acids-rich fraction and α-acids-with-β-acids-rich fraction were also used to test the antioxidative potential. The AA of purified hydroacetonic hop extracts was investigated using the Ferric Reducing Ability of Plasma (FRAP), Oxygen Radical Absorption Capacity (ORAC) and Intracellular Antioxidant (IA) methods.

Metastasizing extra-adrenal paraganglioma with neurological signs in four dogs.

Extra-adrenal paragangliomas associated with vertebral pain and clinical neurological abnormalities as a result of metastasis to the vertebral column were diagnosed in four dogs of different breeds by light microscopy. All were males (two intact and two neutered) aged 8 years. Metastatic neoplasms occurred as extradural masses with associated bone lysis at vertebrae C4 (2 cases), T12-L1 (1 case) and L4 (1 case).

Diskospondylitis associated with Brucella canis infection in dogs: 14 cases (1980-1991).

A retrospective study of 135 dogs with diskospondylitis revealed 14 dogs with concurrent Brucella canis infection. Sexually intact male dogs and dogs in the southeastern United States appeared to be at higher risk. Results of bacteriologic culturing of blood were less likely to be positive for dogs with diskospondylitis caused by B canis infection than for dogs with diskospondylitis caused by other organisms.

Survival of a dog with pneumonia caused by Mycobacterium fortuitum.

Pneumonia caused by Mycobacterium fortuitum was diagnosed in the left lung lobes of a 3-year-old male Samoyed. Unilateral pneumonectomy and antibiotic treatment (primarily amoxicillin trihydrate-clavulanate potassium and kanamycin) were associated with resolution of the pneumonia. In dogs, M fortuitum causes pulmonary disease that radiographically resembles bacterial pneumonia.

Complications following thiacetarsamide sodium therapy in Louisiana dogs with naturally-occurring heartworm disease.

Four hundred and sixteen dogs with naturally-occurring heartworm disease were evaluated for complications following thiacetarsamide sodium therapy. Of these, 109 dogs (26.2%) experienced complications.
