同种异体移植物消除了与自体移植物和合成支架相关的缺点,但与疾病传播风险相关。因此,同种异体移植物绝育是至关重要的。我们的目的是确定聚乙烯吡咯烷酮碘(PVP-I)是否可以用于灭菌和作为一种新的湿保存方法。pvp - i灭菌和保存的同种异体移植物表现出更好的机械性能、成骨能力和良好的微生物抑制能力。裸鼠大腿肌袋模型显示,pvp - i保存的同种异体移植物比co60灭菌的同种异体移植物(对照组)在体内表现出更好的异位形成(P < 0.05)。此外,pvp - i保存组在同种异体移植物保存24 h和12周时无差异(P < 0.05)。pvp - 1灭菌后的同种异体肌腱表面亲水性更强,机械强度高于co60灭菌后的肌腱(P < 0.05)。未洗涤和保存时间延长时,残留PVP-I水平较高(P < 0.05)。玻璃体细胞试验显示,适当浓度的PVP-I对成骨前细胞无毒性,碱性磷酸酶活性和成骨基因标记均能增强成骨前细胞分化(P < 0.05)。因此,植入同种异体移植物的生物学性能的提高可能归因于更好的表面特性和残留的PVP-I, PVP-I浸泡可以是一种简单易行的同种异体移植物灭菌和保存方法。
Allografts eliminate the disadvantages associated with autografts and synthetic scaffolds but are associated with a disease-transmission risk. Therefore, allograft sterilisation is crucial. We aimed to determine whether polyvinylpyrrolidone-iodine (PVP-I) can be used for sterilisation and as a new wet-preservation method. PVP-I–sterilised and preserved allografts demonstrated improved mechanical property, osteogenesis, and excellent microbial inhibition. A thigh muscle pouch model of nude mice showed that PVP-I–preserved allografts demonstrated better ectopic formation than Co60-sterilised allografts (control)in vivo(P < 0.05). Furthermore, the PVP-I–preserved group showed no difference between 24 h and 12 weeks of allograft preservation (P > 0.05). PVP-I–preserved allografts showed more hydrophilic surfaces and PVP-I–sterilised tendons showed higher mechanical strength than Co60-sterilised tendons (P < 0.05). The level of residual PVP-I was higher without washing and with prolonged preservation (P < 0.05).In vitrocellular tests showed that appropriate PVP-I concentration was nontoxic to preosteoblast cells, and cellular differentiation measured by alkaline phosphatase activity and osteogenic gene markers was enhanced (P < 0.05). Therefore, the improved biological performance of implanted allografts may be attributable to better surface properties and residual PVP-I, and PVP-I immersion can be a simple, easy method for allograft sterilisation and preservation.
