人们发现,有些动物受伤后会舔自己的伤口。另外,拔牙后的创口一般都会比创伤等级相当的皮肤或骨头创伤更快地好转。荷兰研究人员发现,这是因为唾液中有一种蛋白能有效加速溃疡、外伤等伤口的愈合。 People find that some animals will lick their own wounds after they have been injured. In addition, wounds after extraction are generally better than wounds with comparable levels of trauma to the skin or bone. Dutch researchers found that this is because there is a protein in saliva that can effectively accelerate the healing of wounds such as ulcers and trauma.
