COMPARAÇÃO DE FERIDAS INDUZIDAS EXPERIMENTALMENTE EM COELHOS TRATADAS COM DIFERENTES FONTES DE PLASMA RICO EM PLAQUETAS

Abstract

Over the years, the platelet-rich plasma (PRP) autologous has been used to great advantage in the healing of acute and chronic wounds. However, some situations make it impossible to use this source, should be considered as alternatives to PRP homologous or heterologous. Aiming to evaluate the effect of platelet-rich plasma (PRP) in autologous, heterologous and homologous form gel on cutaneous wound healing in vivo, 24 rabbits (9 males and 9 females) divided into three groups were used for the experiment and 6 animals (3 males and 3 females) were donors PRP. For the heterologous group, used a dog, adult mongrel to obtain PRP. The lesions were performed using a punch of 8 mm, and the right side was treated with 0.9% NaCl ® (A) and left side (B) applied PRP gel (GA = autologous, GHE=heterologous, and GHO = homologous). Lesions were evaluated for a period of 17 days. On days 0, 3, 7, 10, 14 and 17 animals were clinically evaluated by weight and pain, and on day 17 biopsies were taken for histopathological assessment of wounds. The percentage of contraction was evident in side B (treated) in all groups, which was also confirmed in the microscopic analysis of histological sections. Thus, it was concluded that the PRP, regardless of source, improves and accelerates the healing process, demonstrating their therapeutic potential on skin lesions and can be used in patients with impaired wound healing.
