To evaluate, by the morphometry, the effect of tenoxicam and its diluent in the venous endothelium, were used 48 white male rabbits (Oryctolagus cuniculus), of the New Zealand branch, with age over 10 weeks and weight varying between 2.350 and 3.500 grams. The rabbits were divided in two groups: Experiment and Control, and analyses were conduced in 6, 12 and 24 hours after the procedure. Into the right and left mediales auriculares veins of the Experiment group was injected tenoxicam or tenoxicam and its diluent; in the Control group 0,9% sodium chloride was injected. No statistically significant difference was observed between the animals weight in both groups before the performance of the procedure. It was possible to observe, after the use of tenoxicam with its diluent or the isolated diluent, that the nuclei diameter of the cells of the venous endothelium showed a dimension, markedly smaller when compared to the Control Group, in which was injected 0,9% sodium chloride. The results found allow to conclude that tenoxicam with its commercial or its isolated diluent reduce the nuclei diameter of the cells of the venous endothelium, where they were injected.
