Carbonic anhydrase I (HCAI) concentrations were measured in erythrocytes (RBC) taken from nine women at intervals throughout their pregnancies and from thirteen normal women during the menstrual cycle. No significant changes in RBC HCAI concentrations were found in any instance. Small changes which were found in RBC HCAI concentrations were within experimental error and did not correlate with any other measured parameter. Changes in RBC HCAI concentrations in six men over a four-week period were of similar order to that found in the thirteen normal women over a similar length of time.
在整个孕期，对9名女性不同阶段采集的红细胞（RBC）中的碳酸酐酶I（HCAI）浓度进行了测量，并在月经周期对13名正常女性的红细胞进行了测量。在任何情况下，均未发现红细胞HCAI浓度有显著变化。红细胞HCAI浓度出现的微小变化在实验误差范围内，且与任何其他测量参数均无关联。6名男性在四周内红细胞HCAI浓度的变化幅度与13名正常女性在相同时间内的变化幅度相似。
