目前，我国实验外科研究用犬仍以民间杂种犬为主。在脏器移植，循环系统实验等许多研究中需要对犬的血气指标进行监侧，而民间杂种犬的血气指标正常值尚未见报道。本实验对３６只杂种犬的血气指标进行测定，并与文献报道的Ｂｅａｇｌｅ犬及人的正常血气值进行比较，为应用民间杂种犬的实验研究提供基础资料。 At present, the research dogs used in experimental surgery in our country are still dominated by folk hybrid dogs. In many organ transplantation, circulatory system experiments and many other studies need to monitor the dog’s blood gas index, while the normal blood clots in non-domestic mongrel dogs have not been reported. In this experiment, the blood gas indexes of 36 hybrid dogs were measured and compared with the reported normal blood gas values ​​of Beagle dogs and human in the literature to provide the basic data for the experimental study of the crossbreed dogs.
