The Effect of Apocynin on Fat Graft Survival.

Abstract

In this study, we investigated the effect of apocynin on fat graft survival in a rat model. Twenty-one Wistar albino male rats were included in the study. The grafts taken from the inguinal area were applied to the nape of each rat. The rats were randomly divided into three groups. Apocynin+DMSO, DMSO and saline were administered intraperitoneally once daily for 14days. After 90days, the animals were sacrificed and the grafts were excised. The weights and volumes were measured and sent for histopathological evaluation. The weight, volume, survival rates of the grafts, the number of viable cells with the MTT test and pathological parameters, inflammation, vascularization, fibrosis, lipogranuloma and cyst formation, were evaluated. Statistically significant differences were found between the groups in survival rates (p<0.05). In paired comparisons between the groups, the parameters of viable cells and survival rates were statistically significantly higher in apocynin group compared to the other groups (p<0.05). The survival rates relating to the weight and viable cell count in the DMSO group were statistically significantly higher than in the control group (p<0.05). However, no statistically significant difference was found between the DMSO group and the control group in the survival rate in terms of volume (p<0.05). There was no significant difference between the groups in the comparison of pathological parameters (p>0.05). Apocynin increases fat graft survival in the animal fat grafting model. Therefore, apocynin can be used as an effective medical agent to prevent the volume loss of fat grafts. This journal requires that authors assign a level of evidence to each article.
