Formol-stable serum acid phosphatase (SAP) was measured in 200 patients with symptoms of prostatism, before and at varying time intervals after digital rectal examination. In three separate groups of 50 patients SAP levels were measured before and at 5, 15 and 30 min following rectal examination and in a fourth group of 50 patients it was measured before and at 6, 24 and 48 h after examination. No significant change occurred in SAP levels following this examination in any of the groups studied. We conclude that rectal examination does not raise the SAP and that, contrary to popular belief, blood levels recorded at any time within this 48-h period are reliable.
对200例有前列腺增生症状的患者，在直肠指检前及指检后不同时间间隔测量甲醛稳定血清酸性磷酸酶（SAP）。在三组各50例患者中，分别于直肠指检前及指检后5、15和30分钟测量SAP水平；在第四组50例患者中，于指检前及指检后6、24和48小时测量SAP水平。在所研究的任何一组中，此次检查后SAP水平均未发生显著变化。我们得出结论，直肠指检不会升高SAP，而且与普遍看法相反，在这48小时内任何时间记录的血液水平都是可靠的。
