RESUMO
Over a period of two years four ornamental koi carp (Cyprinus carpio) of one variety in a mixed population of 16 were affected with papillomas of the head and body. In one fish there was a transition of these tumours into a squamous cell carcinoma in the region of the head and posterior gill space, with deep invasion of the underlying bone. One of the fish recovered completely after the sloughing of the papillomas. In view of the progressive nature of the lesions, the condition was presumed to be due to an infectious agent, but transmission electron microscopy failed to reveal any virus particles.

Commercial radioimmunoassay kits for the measurement of human total thyroxine (T4) and total triiodothyronine (T3) based on magnetic separation are discussed for use in dogs and cats. The T4 assay procedure is modified to increase the accuracy over normal canine and feline ranges using four standards from kit components provided. Results of validation are presented and indicative normal ranges given: canine T4, 0.94 to 3.45 micrograms/dl; canine T3, 0.36 to 1.52 ng/ml; feline T4, 1.34 to 4.70 micrograms/dl; feline T3, 0.23 to 0.95 ng/ml. There is a significant breed difference in T4 levels between poodles and Yorkshire terriers.
