Using the Haddad modified method, 25-OH-D were measured in the blood of the umbilical cord of 29 infants and in peripheral serum after 6 weeks. 16 infants were given a daily dosage of 1000 I. E., 13 infants 500 I. E. vitamin D against rickets. Further they were fed with an adapted milk containing 400 I. E. vitamin D/1. The mean cord serum values were 13 and 15 ng/ml. After treatment with 1000 I. E., 25-OH-D values around 54 ng/ml were measured after 6 weeks and under 500 I. E. daily, values of 37 ng/ml, respectively. Treatment using a dosage of 500 I. E. vitamin D combined with feeding with vitamin D fortified milk seems adequate, to prevent vitamin D depletion.
采用哈达德改良法，对29名婴儿脐带血及6周后外周血清中的25-羟维生素D进行了检测。16名婴儿每日服用1000国际单位维生素D预防佝偻病，13名婴儿每日服用500国际单位。此外，他们还喂养了一种每升含400国际单位维生素D的配方奶。脐带血清平均值分别为13和15纳克/毫升。服用1000国际单位治疗后，6周后测得的25-羟维生素D值约为54纳克/毫升，每日服用500国际单位时，该值分别为37纳克/毫升。每日服用500国际单位维生素D并结合喂养维生素D强化奶的治疗方法似乎足以预防维生素D缺乏。
