Age-related changes in the histologic morphology of the Beagle dog prostate have been used as a model for similar changes that occur in human beings. Previous studies of the aging changes in Beagle dogs have been limited to animals less than 10 years of age. In this study, the prostate, testes, and serum testosterone levels were evaluated in healthy Beagle(More)
To distinguish age-related changes in hematology and clinical chemistry values from those resulting from disease, hematology, and clinical chemistry values of healthy, age-matched Beagle dogs 3 to 14 years of age were analyzed. Serum potassium, total protein and globulin concentration, and lactic dehydrogenase activity increased with age, while urea(More)
Serum alpha-fetoprotein (AFP) concentration was detected by use of 2 commercially available kits containing antibodies to human AFP--a radioimmunoassay and an enzymetric test. Using neonatal canine serum (a source high in AFP), it was determined that reagents from both kits were able to bind to canine AFP, but a significant difference was detected in AFP(More)
PURPOSE Anastomotic vessels in exudative age-related macular degeneration (AMD) represent a serious clinical feature that reportedly does not respond well to either photocoagulation or photodynamic therapy (PDT). Anastomoses also occur in various animal models of choroidal neovascularization (CNV). In the present study, anastomotic vessels and their patency(More)
PURPOSE To evaluate and characterize the New-World squirrel monkey as a primate model for experimental choroidal neovascularization (CNV) studies and to compare it with the current Old-World macaque monkey model. METHODS Fibrovascular tissues (FVT) were elicited in 12 maculae of seven squirrel monkeys by laser photocoagulation using optimized laser(More)
