Our professional responsibilities relative to human-animal interactions.

An interesting area with great potential for benefiting and enriching the lives and conditions of people and animals is opening to us in research, service and teaching. By working with colleagues in other disciplines, we can develop new and creative ways to realize the great promise inherent in people-animal interactions properly studied and utilized.Veterinarians who understand that a strong human-companion animal bond can augment people's mental and physical states will help develop sound and effective companion animal programs for individuals who are lonely or handicapped and for persons in the school systems of the community, as well as its hospices, nursing and convalescent homes, prisons and other institutions.

The role of noninvasive tests versus pulmonary angiography in the diagnosis of pulmonary embolism.

We studied 243 patients in whom 248 pulmonary angiograms were performed because of suspected pulmonary embolism. Ventilation and perfusion lung scanning in 140 of them revealed 38 to be in low and high probability groups. Of 19 patients with subsegmental and nonsegmental perfusion defects that were matched with ventilation defects, none had pulmonary embolism.

The scope of a laboratory animal program needed at a veterinary school.

The discipline of laboratory animal medicine is one of the most rapidly expanding specialties within the veterinary profession. Veterinary schools should fully accept the responsibility for introductory instruction in laboratory animal medicine in the professional curriculum. Such instruction should articulate the varied opportunities that exist for the laboratory animal veterinarian within the biomedical research community, and provide an overview of the normal biological characteristics and pathologic conditions of the common laboratory animal species.

Studies on the prevalence of type C virus associated with gibbon hematopoietic neoplasms.

Gibbon malignancy frequently involves the hematopoietic system and can occur in clusters. Virus isolated from gibbon neoplasms possessed typical type C virus morphology, and the virion measured 100 nm in diameter with an electron-dense nucleoid measuring approximately 75 nm. The virus incorporated 3H-uridine into the nucleic acid and rested at a buoyant density of 1.
