BackgroundThe aim of this study was to investigate the effects of acrylamide (AA) on fracture healing histologically, biochemically, and radiologically in a rat femur fracture model.MethodsScanning electron microscopy (SEM) imaging and Fourier transform infrared spectroscopy (FTIR), and UV (ultraviolet)-Vis (visible) spectrophotometer examination were performed for acrylamide characterization. In this study, after the femur fracture model was created, the groups were formed to include eight rats in each group (G) as follows: G1: 15th-day control, G2: 15th-day AA, G3: 30th-day control, G4: 30th-day AA. In G2 and G4, 5mg/kg acrylamide was administered 3 times a week by gastric gavage. The fracture was evaluated radiologically according to Lane-Sandhu scoring and histologically according to Huo scoring. The weight changes of the rats were recorded. Albumin, total protein, cholesterol, HDL, LDL, triglyceride, ALP, LDH, vit. D, PTH, Ca, P, WBC, Hb, Plt values were examined in the blood samples. The data were analyzed using the SPSS program.ResultsThe characterization properties of acrylamide were confirmed. No significant weight change was observed in the rats during the study. When blood values were compared, a statistically significant difference was determined between albumin, total protein, phosphorus, white blood cell (WBC), and hemoglobin groups (p=0.41, p=0.00, p=0.003, p=0.019, and p=0,017, respectively). According to the histological score comparisons, G3 was significantly different from G1, G2, and G4 (p<0.05), and G4 was significantly different from G1 and G2 (p<0.05). According to Lane-Sandhu scoring, there was a significant difference between G2 and G3 and G4 (p: 0.0, p: 0.034), G1 and G3 (p: 0.001), respectively.ConclusionAA adversely affects fracture healing even at low doses, as in the present study. According to the results of this study, the authors recommend a diet poor in acrylamide during fracture treatment. Therefore, further human studies are required to find out the complex effect of AA on bone healing and the body.
