血管渗透性的改变及随之所发生的渗出现象及白血球游出在炎症发展的动力学方面占有很重要的地位。这些生理学现象,如果仅仅从先炎症病灶所发生的生理化学方面的变化着手,是不可能找到很好的解释的。МеНКИН氏曾在炎症渗出物中分离出一种对血管渗透性及白血球游出有影响的一种晶形物质,称之为白血球诱导素,作者认为这种白血球诱导素与组织胺 Changes in vascular permeability and consequent exudation and leukocyte emigration play an important role in the kinetics of inflammation development. These physiological phenomena can not be well explained if only from the changes in the physiochemical aspects of the first inflammatory lesions. МеНКИН ’s inflammatory exudate was isolated in a vascular permeability and leukocyte out of an influential crystalline form of material, called leukocyte inducer, the author believes that this leukocyte inducer and histamine
