An inflammatory reaction was produced in the skin of the chicken by various stimuli. Then the colloidal carbon technique was used to identify vessels showing an increased permeability. The type of vessel affected, the extent and duration of reaction after each procedure were compared. Intradermal histamine, 5-hydroxytryptamine and bradykinin caused extensive but transient carbon labelling which was confined to venules. Topical application of xylol produced a more persistent delineation of venules. Intradermal turpentine and carrageenin affected extensive and restricted portions, respectively, of venules, and to a lesser extent capillaries. Following thermal injury of 65 degrees C for 30 sec, the superficial capillary network was initially involved but the venular response persisted for up to 18 h. These findings are compared and contrasted with those reported in laboratory animals. The possibility of distinction between direct vascular injury and chemical mediation is discussed.
通过各种刺激在鸡的皮肤中引发炎症反应。然后使用胶体碳技术来识别显示通透性增加的血管。比较了每种操作后受影响血管的类型、反应的程度和持续时间。皮内注射组胺、5-羟色胺和缓激肽会导致广泛但短暂的碳标记，且仅限于小静脉。局部涂抹二甲苯会使小静脉的轮廓显示得更持久。皮内注射松节油和角叉菜胶分别影响小静脉的广泛和受限部分，对毛细血管的影响较小。在65摄氏度热损伤30秒后，浅表毛细血管网最初会受到影响，但小静脉反应会持续长达18小时。将这些发现与实验室动物的报告结果进行了比较和对比。讨论了区分直接血管损伤和化学介导的可能性。
