Abstract:
Objective:To study the effects of insulin and berberine on osseointegration of titanium implant in type Ⅱ diabetic rats.Methods:10 out of 53 SD rats were randomly selected and selected into H group(healthy group)(n =10).The remaining rats were treated with high glucose diet plus low dose of streptozotocin(STZ) and 40 rats were induced into the models of type Ⅱ diabeties.The 40 dibetic rats were randomly divided into group B(berberine),group Ⅰ(insulin),group IB(insulin + berberine) and group N(without treatment).2 pure titanium implants were implanted into the bilateral femoral metaphysis of each rat.Mter 7,32,38,66 and 101 d,the body weight(BW) and fasting blood glucose(GLU) were measured.After 10 week,the rats were sacrifice,femoral metaphysis samples were subjected to Micro-CT scan,VG staining and implant pull-out test.Hard tissue slices were observed;bone volume fraction(BV/TV),Liang Houdu (Tb.Th),trabecular bone trabecular number(Tb.N),Liang Jianxi (Tb.Sp),trabecular bone trabecular bone volume (TBV),bone contact ratio(BIC) and the maximum pull-out strength (MPF) were measured.Results:There was no significant difference of BW and GLU between IB group and H group(P ＞ 0.05),but the BW and GLU of IB group was better than those of Ⅰ group and B group,Ⅰ group and B group were better than those of group N (P ＜ 0.05).BV/TV,Tb.Th,Tb.N,Tb.Sp,TBV,BIC and MPF of IB group were not statistically different from those of H group(P ＞0.05);but the indexes of IB group were higher than those of Ⅰ group and B group,those of Ⅰ group and B group were higher than those of N group (P ＜ 0.05).Conclusion:The combination of insulin and berberine can effectively reduce blood glucose and can promote osseointegration of titanium implants in type Ⅱ diabetic rats.
