Resumo
The morphometric method is widely used for the measurement of wounds, however,
the use of rulers may generate inaccurate results, facilitates the contamination of the
wound and cause discomfort to the animal during the measurement. In this context, the image analyzer program Image J could be a promising tool to measurement of
skin wounds. The aim of this study was to determine if the digital morphometric
analysis by Image J is efficient in the measurement of skin wounds in comparison
with the basic mathematical method of measuring. It was used six New Zealand
rabbits healthy. The animals were anesthetized and a wound was made on the
dorsum of each animal with a circular metal punch. The wounds were measured by
two methods: mathematical method established by the equation A = π.Rr, A = total
area, π = 3.14, R = greater radius wound, r = smaller radius wound, representing the
group I (GI), and measurement of the wound by the program Image J, Group II
(GII). The average of the area measured was 0.72 cm2 0.66 cm2 GI and GII, with no
statistical difference between groups. Despite the lack of difference between the
methods, measurement of the wound area by Image J provided accurate values as
the basic mathematical method, without bringing contamination risks or discomfort to
the animal. Furthermore, the lack of statistical difference demonstrates that the
Image J can replace the mathematical method without losses and reduce the
subjectivity of the results.
