摘要:

背景:纳米羟基磷灰石与聚氨酯复合材料在体外实验中具有良好的相容性。
目的:验证纳米羟基磷灰石膜聚氨酯复合材料在大鼠体内的组织相容性。
方法:将18只SD大鼠随机分为复合材料组、聚氨酯组和对照组,复合材料组和聚氨酯组分别将纳米羟基磷灰石膜聚氨酯复合材料、聚氨酯植入大鼠背部肌肉内,对照组仅作切开缝合,未植入任何材料。
结果与结论:
①大体观察:术后12周,各组切口与周围皮肤几乎无界限,聚氨酯组及复合材料组囊壁与材料融合较好,对照组皮肤已恢复正常。②组织学观察:术后4,8,12周,聚氨酯组及复合材料组切口周围组织中淋巴细胞数、中性粒细胞数及毛细血管量均高于对照组(P < 0.05),复合材料组切口周围组织中淋巴细胞数、中性粒细胞数及毛细血管量均少于聚氨酯组(P < 0.05)。证实纳米羟基磷灰石膜聚氨酯复合材料具有较好的组织相容性。

Abstract:

BACKGROUND: Nano-hydroxyapatite/polyurethane has been verified to have an excellent biocompatibility in vitro.
OBJECTIVE: To explore the biocompatibility between nano-hydroxyapatite/polyurethane composite and mouse tissues.
METHODS: Eighteen Sprague-Dawley rats were randomly divided into nano-hydroxyapatite/polyurethane group, polyurethane group and control group. Polyurethane and nano-hydroxyapatite/polyurethane were implanted into the back of rats, respectively, in the polyurethane and nano-hydroxyapatite/polyurethane groups. Nothing was implanted in the control group.
RESULTS AND CONCLUSION: (1) Body observation: Incision and surrounding skin almost had no boundaries in all the groups 12 weeks after operation. The capsule wall of polyurethane and nano-hydroxyapatite/ polyurethane groups was confluent well with the implant materials, and the skin of the control group recovered. (2) Histology observation: The number of lymphocytes, neutrophils and capillary vessels around the incisions was higher in the polyurethane and nano-hydroxyapatite/polyurethane groups than the control group (P < 0.05). In addition, nano- hydroxyapatite/polyurethane group has fewer lymphocytes, neutrophils and capillary vessels than the polyurethane groups (P < 0.05). It is verified that nano-hydroxyapatite/polyurethane composite has a better histocompatibility.
