Biomicroscopic and histologic pathology of the eye in riboflavin deficient rainbow trout (Salmogairdneri).

Quadruplicate lots of 35 fingerling rainbow trout (mean body weight 11.2 g) were fed for 20 weeks a complete diet or one deficient in riboflavin. Five fish from each low were examined for ocular lesions each week. At the end of the experiment eyes of three fish form each lot were examined histologically. Beginning with the 14th week, epithelial changes were present in the cornea; they appeared as thickening of the stroma and endothelium and resulted in clouding. Opacity of the lens originated in the posterior subcapsular cortex and progressed to lens fiber autolysis and liquefaction.

Teratogenesis in cats associated with griseofulvin therapy.

Multiple congenital malformations occurred in kittens of three cats treated orally at weekly intervals with 500-1000 mg of the antifungal drug griseofulin. Malformations of the brain included exencephaly, malformed prosencephalon, caudal displacement, and hydrocephalus. Skeletal malformations included cranium bifidium, spina bifida (C1 through C4, and sacral), abnormal atlantooccipital articulation, cleft palate, absence of maxillae, and lack of tail vertebrae. Cyclopia and anophthalmia with absence of optic nerves and rudimentary optic tracts were also observed. Atresia ani, atresia coli, lack of atrioventricular valves in the heart, and absence of external nares and soft palate were other abnormalities present.

Tetracycline and niacinamide for the treatment of sterile pyogranuloma/granuloma syndrome in a dog.

A sterile pyogranuloma/granuloma syndrome in a dog is described. Diagnosis was based on cytological examinations of the skin and lymph nodes and histopathological examinations of the skin and nictitans. Although the condition initially was responsive to large doses of glucocorticoids, it subsequently was treated successfully with tetracycline and niacinamide. The excellent responses of this dog suggest that this drug combination may be a viable therapeutic option for dogs in which glucocorticoids cannot be used.
