In a study of the vitamin C status of 50 patients with malignant disease, 46 had leucocyte levels less than the lower limit of the normal range (18-50,μg/10(8) W.B.C.) and of these 30 had very low levels (< 12.5 μg/10(8) W.B.C.). Physical signs compatible with subclinical scurvy were frequently recorded and there was a significant decrease in capillary fragility in those with the lowest levels. Most patients had an inadequate dietary intake of ascorbic acid-containing foods and this was felt to be the major factor in producing the vitamin depletion.
在一项针对50名恶性疾病患者维生素C状况的研究中,46名患者的白细胞水平低于正常范围下限(18 - 50μg/10⁸白细胞),其中30名患者的白细胞水平极低(< 12.5μg/10⁸白细胞)。经常记录到与亚临床坏血病相符的体征,且白细胞水平最低的患者毛细血管脆性显著降低。大多数患者饮食中抗坏血酸含量丰富的食物摄入不足,这被认为是导致维生素缺乏的主要因素。
