The authors submit further experience with two-photon absorption measurement of the mineral content of the lumbar spine using a NOVO/Lab BMC 22a (Denmark) apparatus. 1. The authors discuss the problem of evaluation of results in postmenopausal women. For the basic evaluation the authors use the range +/- 2 s of "normal" values classified by decades; another suitable guide to the interpretation could be extrapolation of the lower range of the regression zone in recorded in premenopausal women to higher age groups. 2. The histogram of frequencies of normal values in women in g.cm-2 has two peaks corresponding to the group of premenopausal women and the group of postmenopausal women. 3. Of 573 examined patients with osteoporosis 295, i. e. 51.5%, cannot be reliably evaluated or cannot be evaluated at all (as a rule because of changes of the spine). Of 49 results obtained in men with osteoporosis 34.7% are within the normal range, of 229 results obtained in women with osteoporosis 47.2% are within the normal range. The hitherto assembled experience is consistent with the view that the method is useful and invaluable in particular for the long-term follow up of patients.
作者提交了使用丹麦NOVO/Lab BMC 22a仪器对腰椎矿物质含量进行双光子吸收测量的更多经验。1. 作者讨论了绝经后女性结果评估的问题。对于基本评估，作者使用按十年分类的“正常”值的±2s范围；另一个合适的解释指南可以是将绝经前女性记录的回归区下限外推到更高年龄组。2. 以克/平方厘米为单位的女性正常值频率直方图有两个峰值，分别对应绝经前女性组和绝经后女性组。3. 在573名接受检查的骨质疏松症患者中，有295名（即51.5%）无法得到可靠评估或根本无法评估（通常是由于脊柱变化）。在49名男性骨质疏松症患者的结果中，34.7%在正常范围内，在229名女性骨质疏松症患者的结果中，47.2%在正常范围内。迄今为止积累的经验与以下观点一致，即该方法尤其对患者的长期随访有用且非常重要。
