Alpha-naphthyl acetate esterase (ANAE) activity was studied in cells forming rosettes with sheep and mouse erythrocytes. In adult peripheral blood, on the average 74% of E-rosette-forming cells expressed simultaneous focal ANAE activity, whereas most cells forming rosettes with mouse erythrocytes were negative. No difference was observed in ANAE-staining proportions of active and total E-rosette forming cells in adult peripheral blood. The proportions of total and active E-rosette and M-rosette forming cells were similar in adult peripheral blood and cord blood lymphocytes. However, the mean percentage of cord blood total E-rosette-forming cells expressing ANAE activity (61%) was significantly lower (P less than 0.001) than in adult peripheral blood.
对与绵羊和小鼠红细胞形成花环的细胞中的α-萘乙酸酯酶（ANAE）活性进行了研究。在成人外周血中，平均74%的E花环形成细胞同时表达局灶性ANAE活性，而大多数与小鼠红细胞形成花环的细胞为阴性。在成人外周血中，活性和总E花环形成细胞的ANAE染色比例未观察到差异。成人外周血和脐血淋巴细胞中总E花环和M花环形成细胞以及活性E花环形成细胞的比例相似。然而，脐血中表达ANAE活性的总E花环形成细胞的平均百分比（61%）显著低于成人外周血（P<0.001）。
