基于对紫外线（ＵＶ─Ｂ）预防佝偻病有效剂量和安全限界的研究．以１／８ＭＥＤ为保健日光灯预防佝偻病的应用剂量，于１９９３年冬春季期间对沈阳某托幼机构（３例）和家庭（１例）婴幼儿（含部分早期佝偻病患儿）实施照射，同时设立对照１８例．结果表明：实验组在照射后无新病例发生．血清２５０ＨＤ３较照射前平均增加８．０６±１．９８ｎｇ／ｍｌ．差别极为显著，原早期佝偻病患儿照射后腕部Ｘ片、体征和症状均有不同程度好转；而对照组血清２５０ＨＤ３的变化则均无统计学意义．腕部Ｘ片、体征和症状不仅未见改善．反有加重趋势。这表明保健日光灯具有肯定的预防佝偻病效果．且兼有对早期佝偻病的一定治疗作用．
Study on Effective Dose and Safety Limits for Prevention of Rickets by UV-B. To 1 / 8MED for health fluorescent to prevent rickets application dose, in the spring and winter of 1993, a nursery in Shenyang (3 cases) and family (1 case) infants (including some early rickets in children) to implement the same time, set up Control 18 cases. The results showed that there was no new case in experimental group after irradiation. Serum 250HD3 than before irradiation increased by an average of 8.06 ± 1.98ng / ml. The difference was extremely significant. The original radiographs of wrist X-ray, signs and symptoms of rickets were improved to some extent in the original patients. However, the changes of serum 250HD3 in the control group were not statistically significant. Wrist X-ray, signs and symptoms not only did not improve. Instead, increase the trend. This shows that health fluorescent lamps have a positive effect of preventing rickets. And both have a certain therapeutic effect on early rickets.
