目的:测定血清中维生素A的含量与生长、营养状况及血液学状况的关系,及其含量与镰刀细胞性疾病- SS(S等位基因纯合子,SCD-SS)住院患儿数量的关系。试验设计:选择2-9.9岁的患有SCD-SS的患儿, 测定其血清维生素A、血色素、红细胞比积、网织红细胞计数、患儿的身高、体重、身体质量指数及以往的饮食摄入量。维生素A含量的定义以血清中维生素A的浓度为基准,当浓度<3 mg/L为异常,浓度≥3 mg/L为正常。在评估维生素A含量后,住院患儿人数的确定持续了1 年。结果:在66例受试者中(39例女孩),平均血清维生
OBJECTIVE: To determine the relationship between vitamin A content in serum and growth, nutritional status and hematological status, and its relationship with the number of hospitalized sickle cell disease-SS (S allele homozygote, SCD-SS). Experimental design: Children aged 2-9.9 years with SCD-SS were selected for determination of serum vitamin A, hemoglobin, hematocrit, reticulocyte count, height, weight, body mass index and previous diet Into the amount. The definition of vitamin A content of serum vitamin A concentration as a benchmark, when the concentration of <3 mg / L is abnormal, the concentration of 3 mg / L is normal. After assessing the vitamin A content, the number of hospitalized children persisted for 1 year. Results: In 66 subjects (39 girls), mean serum mean survival was obtained
