您要查找的是不是：
- TUNEL result of apoptotic cells:TUNEL-positive cells were detected in the alumina particle group and HMWPE particle group,which were brown staining. No severe cellular reaction was found in the control group. 凋亡细胞TUNEL原位检测结果:氧化铝陶瓷磨损颗粒组、高分子聚乙烯磨损颗粒组均存在TUNEL染色阳性细胞,细胞核着染成棕褐色或棕色,模型对照组未见明显组织细胞反应。
- Meanwhile, modifying the surface of the alumina particle before grinding can reduce the particle's surface energy and prevent the fine particles from aggregating. 同时，在氧化铝粉碎前添加了表面分散剂之后，降低了颗粒的表面能，防止了粉碎后颗粒的再团聚，改善了粉碎的效果。
- The air pouches were injected with 3 mL alumina particles suspension into the alumina particle group,while 3 mL HMWPE particles suspension was injected in the HMWPE particle group; the control group was given matching phosphate buffered saline. 氧化铝陶瓷磨损颗粒组向air-pouch内注射经超声分散后的氧化铝陶瓷磨损颗粒悬液3mL,高分子聚乙烯磨损颗粒组注射高分子聚乙烯磨损颗粒悬液3mL,模型对照组注射等量磷酸盐缓冲盐水。
