本文观察了流感病毒的皮肤反应及其引起的组织学改变与循环抗体的产生等问题。皮肤反应试验结果表明,一般在注射几小时后反应(直径在5毫米以上者称为阳性)才明显,约于24小时达到高峰,于48小时反应稍退,然后再持续几天。组织学的研究表明,甲型和乙型流感病毒引起大量的淋巴细胞和单核细胞的浸润,多半聚积在小血管周围,也有少量浸润在汗腺和皮肤附器周围。有很少量的肥大细胞。冰冻切片检查免疫球蛋白和 In this paper, we observed the skin reactions of influenza virus and the histological changes and the production of circulating antibodies. The skin reaction test results show that the reaction is generally evident after hours of injection (positive in diameter above 5 mm), peaked at about 24 hours, slightly delayed at 48 hours, and then continued for several days. Histological studies have shown that influenza A and B viruses cause a large number of infiltration of lymphocytes and monocytes, mostly accumulate in the small blood vessels, but also a small amount of infiltration in the sweat glands and skin appendages around. A small amount of mast cells. Frozen section examination of immunoglobulins and
