对8例乳糖酶(NL)正常者和7例乳糖酶缺陷者(LD)的肠道钙吸收进行了研究，以确定乳糖酶缺乏是否与钙吸收有关。将结果与在水溶液中摄入钙的数据进行了比较。用双同位素技术测定了钙的吸收，用去卷积法得到了动力学指数。使用(-)时，NL和LD受试者的钙吸收是相同的，但略高于水溶液(15%，NS)。有(+)者，NL组钙吸收与水溶液相同，LD组增加23%，P<0.02。这些数据表明：从牛奶和从水溶液中吸收CA的效果一样好；(+)有利于LD受试者的钙吸收，这表明LD受试者可能鼓励摄入牛奶以避免缺钙；(-)应该是乳糖不耐受患者的一种有价值的替代方案。
Intestinal calcium absorption from milk containing lactose (+) and from another containing glucose (-) was studied in eight patients with normal lactase (NL) and seven lactase-deficient (LD) subjects to determine if lactase deficiency is implicated in Ca absorption. The results were compared with data obtained from Ca ingestion in a water solution. Ca absorption was measured by a double-isotope technique and the kinetic indices were obtained by a deconvolution method. With (-), Ca absorption was identical in NL and LD subjects and slightly higher than with water solution (15%, NS). With (+), Ca absorption in NL subjects was identical with that from water solution; in LD subjects it increased (23%, p less than 0.02). These data indicate that: Ca is absorbed equally well from milk as from water solution; (+) favors Ca absorption in LD subjects, which suggests that milk ingestion might be encouraged in LD subjects to avoid Ca deficiency; and (-) should be a valuable alternative for lactose-intolerant patients.
