Zinc levels in plasma and leucocytes of elderly patients with and without cutaneous ulcers and in hospital were compared with those of a group of healthy elderly living at home and of a younger group. The groups in hospital had lower levels of plasma and leucocyte zinc than the control groups, but these were not associated with cutaneous ulcers. The zinc intake of the patients in hospital was well below the recommended daily allowance. Tissue zinc levels were found to be low in elderly patients in hospital, probably due to poor intake, but their contribution to the formation of skin ulcers was unproven.
对住院的有皮肤溃疡和无皮肤溃疡的老年患者血浆和白细胞中的锌水平，与一组居家健康老年人及较年轻组进行了比较。住院组患者血浆和白细胞中的锌水平低于对照组，但这与皮肤溃疡无关。住院患者的锌摄入量远低于推荐的每日摄入量。住院老年患者的组织锌水平较低，可能是由于摄入不足，但它们对皮肤溃疡形成的影响尚未得到证实。
