The activity of the endothelial and macrophage derived angiotensin-converting enzyme in blood was within normal range in 12 patients with histiocytosis X, independent of extent and activity of the disease. In contrast to sarcoidosis and Gaucher's disease, histiocytosis X is not associated with elevated levels of angiotensin-converting enzyme.
12例组织细胞增多症X患者血液中内皮细胞和巨噬细胞衍生的血管紧张素转换酶活性在正常范围内，与疾病的范围和活动度无关。与结节病和戈谢病不同，组织细胞增多症X与血管紧张素转换酶水平升高无关。
