For centuries, mankind has been incessantly researching with drugs that could accelerate the normal wound healing process. In the Hospital de Clinicas da Universidade Federal do Paraná, it has been recommended that the cleansing of clean wounds with saline solution of 0.9% sodium chloride, followed by a cover of dry dressing. However, some services have empirically used Agarol and Trigliceril in the confection of dressings after cleansing. This study aimed to evaluate the evolution of cutaneous wounds treated with normal saline, Agarol and Trigliceril in rats. A group of twenty-four rats were submitted to three skin circular incisions of 1.2 cm in diameter on their backs which exposed the subcutaneous tissue. The wounds were cleaned daily with normal saline solution. This group was distributed at random within three groups: Group C, control, received a clean and dry dressing after cleansing; groups A and T received dressings with Agarol and Trigliceril respectively. The evaluation of the wounds was done on the 3rd, 7th and 14th postoperative days by histological and macroscopic studies. The results showed that on the 3rd and 14th days, no evident influence of the drugs on the healing wound was noticed. On 7th postoperative day, Agarol demonstrated to increase the amount of granulation tissue, while Trigliceril appears to decrease the neovasculature during the healing process.
