摘要
Abstract
[Objective] To evaluate the possible function of NO in fracture healing. [Methods] 120 Wistar rats were divided into 3 groups including L-arginine, L-NAME and the control group. The closed fractured model of each rat was built in the right femur. The callus of the fractured site was amputated and observed by the gross appearance and HE stain in the 3rd day, the first, second and fourth week after fracture. [Results] The gross observation of fracture in different stage indicated relatively small callus after the L-NAME intake. This was the same with the callus modelliing. Compared to these findings, completely opposite results were seen in the L-arginine group.When compared to the control group, the tendency of fracture healing was seen in the L-NAME group, but it had no significant difference (P =0.1). The degree of remodeling of the bone and fracture healing in the group of L-arginine was stronger than that in L-NAME (P <0.05). [Conclusion] L-NAME' s intake will inhibit the process after the fracture, which indicates NO may play an important role in the process of fracture healing.关键词
