Acid phosphatase activity was detected in the Malpighian tubules of the blood-sucking hemipteran, Triatoma infestans. The enzyme activity was especially prominent in the cytoplasmic globules which were assumed to be laminated 'concretions', which occur in the distal cells of the organ. It was also verified in the nuclei and in some cytoplasmic granules (lysosomes) of the proximal cells. The data indicated that lysosomes were involved with the nature or origin of the laminated concretions, but it is still questionable whether acid phosphatase activity exists in the nuclei.
在吸血半翅目昆虫——克氏锥虫的马尔皮基氏小管中检测到了酸性磷酸酶活性。该酶活性在细胞质球中尤为显著，这些细胞质球被认为是层状“凝块”，出现在该器官的远端细胞中。在近端细胞的细胞核和一些细胞质颗粒（溶酶体）中也得到了证实。数据表明溶酶体与层状凝块的性质或起源有关，但酸性磷酸酶活性是否存在于细胞核中仍存在疑问。
