如何可靠地预测青霉素的过敏反应是一个有理论性和临床实用性的问题。以往本室和其它实验室曾研究用适当的试剂做皮内试验。我们曾用过:1)青霉噻唑—聚赖氨酸和2)用微量的一种混合物包括有青霉素及其水解产物:青霉噻唑酸、青霉噻唑酰胺和青霉酸。近来设计了一种改良的皮试剂,受到美国国立过敏和感染病研究所(NIAID)的推崇,为多所临床中心采用。这新的试剂是 How to reliably predict the allergic reaction of penicillin is a theoretical and clinical practical problems. In the past this room and other laboratories have studied using an appropriate reagent intradermal test. We have used: 1) Penicillin-polylysine and 2) A mixture of penicillin and its hydrolysates, penicillin, penicillin and penicillanic acid, in a trace amount. Recently, an improved dermal agent has been designed that is highly regarded by the National Institute of Allergy and Infectious Diseases (NIAID) and is used by many clinical centers. This new reagent is
