Pigmentary Abnormalities Of The Macula In Rhesus Monkeys: Clinical Observations, R W. Bellhorn, C D. King, Gustavo D. Aguirre, H Ripps, I M. Siegel, H C. Tsai

Gustavo D. Aguirre, VMD, PhD

In a survey of 546 rhesus monkeys of various ages, 6.1% of the animals showed ophthalmoscopically visible hypopigmented spots in their maculas. There was a statistically significant correlation between the age of the animal and the degree of hypopigmentation. Electroretinographic responses and visually evoked potentials were evaluated in a selected group of monkeys with and without hypopigmented macular spots. No significant change in retinal function as a result of the macular abnormalities could be detected.

Gyrate Atrophy Of The Choroid And Retina In A Cat, D L. Valle, A P. Boison, P Jezyk, Gustavo D. Aguirre Jan 1981

Gyrate Atrophy Of The Choroid And Retina In A Cat, D L. Valle, A P. Boison, P Jezyk, Gustavo D. Aguirre

Gustavo D. Aguirre, VMD, PhD

An adult male, domestic short-haired cat with generalized retinal atrophy was found to have a 60-fold increase in plasma ornithine and ornithinuria. Ornithine-8-aminotransferase activity was undetectable in its tissues and in its cultured skin fibroblasts. This feline condition is thus analogous to gyrate atrophy of the choroid and retina in humans.

Family Medicine As A Social Science, Barry Hoffmaster

C. Barry Hoffmaster

The branch of clinical medicine most likely to qualify as a social science is family medicine. Whether family medicine is a social science is addressed in four steps. First, the nature of family medicine is outlined. Second, the extent to which social science knowledge is used in family practice is discussed. Third, the extent to which family medicine can qualify as a social science is considered with respect to an orthodox model of the social sciences, that is, one that emphasizes affinities between the natural and social sciences. Finally, the same question is addressed with respect to an unorthodox model …
