目的
2
优化猪源纤维蛋白贴(简称“DBT”)的配方。
方法
2
在单因素实验的基础上,以冻干前的纤维蛋白原、凝血酶和胶原蛋白含量为考察因素,以黏合强度、持黏力和吸水力的总评归一化(OD)值为响应值,采用Box-Behnken-响应面法优化DBT的配方,并进行验证。
结果
2
根据单因素实验和Box-Behnken-响应面法优化结果,结合实际生产,得DBT的最优配方为纤维蛋白原含量6.5 mg/cm
2
、凝血酶含量8.0 IU/cm
2
、胶原蛋白含量5.6 mg/mL;3次验证实验的平均OD值为0.726 6(RSD=0.58%,
n
=3),与预测OD值(0.733 0)的相对误差为-0.87%。
结论
2
所得DBT的最优配方稳定、可行。
OBJECTIVE
2
To optimize the formulation of a porcine fibrin patch (abbreviated as “DBT”).
METHODS
2
Based on single-factor tests, with the contents of fibrinogen, thrombin and collagen before freeze-drying as the factors, with the overall desirability (OD) value of adhesion strength, holding viscosity and water absorption as response value, the formulation of DBT was optimized by Box-Behnken-response surface methodology, and the verification tests were conducted.
RESULTS
2
According to the results of the single factor tests and Box-Behnken-response surface methodology, combined with the actual production, the optimal formulation of DBT was 6.5 mg/cm
2
of fibrinogen, 8.0 IU/cm
2
of thrombin and 5.6 mg/mL of collagen. The average OD value of 3 validation tests was 0.726 6 (RSD=0.58%,
n
=3), and the relative error of which with the predicted value (0.733 0) was -0.87%.
CONCLUSIONS
2
The optimal formulation of DBT is stable and feasible.
