A histological study for the effect of Platelet-Rich Plasma (PRP) therapy on muscular contusions in Iraqi Arabian horses

Platelet-rich plasma (PRP) is regarded as a modern therapeutic technique in horses, so there are few researches . The study is conducted on eight Iraqi Arabian horses, which are divided equally and randomly into two groups, treatment and control group. Autologous PRP is prepared for treatment group. All experimental horses are exposed to hard trauma causing muscular contusions. Treatment group were treated two times a week for six weeks. Due to the effect of many growth factors, the results show benefit effect of PRP, perfuse granulation tissue which is characterized by excellent proliferation of fibroblasts and highly proliferation of endothelial cells to form new blood vessels. This study according to our knowledge is the first research in muscular contusions of Arabian horses, which is focusing on the histological effect of autologous PRP on the muscular contusions which is very common acute injuries in Iraqi Arabian horses.
