A clinical and immunologic study was performed comparing a group of French patients allergic to the pollens of cypress (Cupressus sempervirens, which belongs to the Cupressaceae family) and a group of Japanese patients allergic to the pollens of Sugi (Cryptomeria japonica, which belongs to the Taxodiaceae family). By skin testing, RAST, and RAST inhibition, clear cross-reactivity was detected between the two pollens. No cross-reactivity was detected between the pollens of Cupressus sempervirens and Sugi and the Pinaceae family. In addition, one can speculate that an antigen in Cupressus sempervirens is cross-reactive with SBP, the major allergen of Sugi, suggesting that there is a closer relationship between the Taxodiaceae family and the Cupressaceae family than between these two families and the other families of the gymnosperms. This finding throws new light on the taxonomy of the gymnosperms.
开展了一项临床和免疫学研究，比较了一组对柏树（地中海柏木，属于柏科）花粉过敏的法国患者和一组对柳杉（日本柳杉，属于杉科）花粉过敏的日本患者。通过皮肤试验、放射变应原吸附试验（RAST）和RAST抑制试验，检测到两种花粉之间存在明显的交叉反应性。在地中海柏木和柳杉的花粉与松科植物的花粉之间未检测到交叉反应性。此外，可以推测地中海柏木中的一种抗原与柳杉的主要变应原SBP具有交叉反应性，这表明杉科与柏科之间的关系比这两个科与裸子植物的其他科之间的关系更为密切。这一发现为裸子植物的分类学提供了新的线索。
