          Abstract

          RESUMO Este artigo descreve a ocorrência, características botânicas, fitoquímicas e a composição nutricional do feijão guandu [Cajanus cajan (L.) Millsp], e sua relação no processo de inibição da falcização na doença falciforme, um distúrbio genético que acomete as hemácias, gerando hemólise e anemia crônica. Dois constituintes químicos estariam mais relacionados aos efeitos inibitórios na falcização de células falciformes: L-fenilalanina e o ácido p-hidroxibenzóico. Estudos químico-biológicos detalhados com o feijão guandu no Brasil poderão esclarecer melhor os mecanismos pelos quais ocorre a inibição da falcização das hemácias e a diminuição do estresse oxidativo, ajudando no tratamento de pessoas com DF.

          ABSTRACT This article describes the occurrence, botanical characteristics, phytochemical and nutritional composition of pigeonpea [Cajanus cajan (L.) Millsp], and their relationship in the process inhibition of sickling in sickle cell disease (SCD), a genetic disorder that affects red blood cells, causing hemolysis and chronic anemia. Two chemical components would be related to the inhibitory effect on sickling of sickle cells: the L-phenylalanine and the p- hydroxybenzoic acid. In Brazil, detailed studies with pigeonpea chemical-biological may clarify the mechanisms by which the inhibition of sickling of red blood cells occurs, reducing oxidative stress and thus helping treating people affected by this disease.

              Effect of zinc supplementation on growth and body composition in children with sickle cell disease.

              Poor growth and delayed maturation in children with sickle cell disease (SCD) may be due, in part, to mild zinc deficiency. The objective was to determine the effects of zinc supplementation on growth and body composition in children with SCD. Forty-two prepubertal children (20 girls and 22 boys) aged 4-10 y with SCD-SS were randomly assigned to receive 10 mg elemental Zn/d in cherry syrup (zinc group) or cherry syrup alone (control group). The 2 groups were stratified by sex and initial height status. Dietary intakes were evaluated and anthropometric, high-precision knee-height, and plasma zinc measurements were made at baseline and at 3, 6, and 12 mo. Body composition was determined every 6 mo with dual-energy X-ray absorptiometry, and z scores for anthropometric variables were computed from national reference data. Longitudinal-mixed-effects analysis was used to test for differences between the groups over the 12-mo observation period. Thirty-eight children completed the study. No significant differences were observed at baseline. After 12 mo, the zinc group had significantly greater mean (+/- SE) increases in height (0.66 +/- 0.29 cm/y), sitting height (0.97 +/- 0.40 cm/y), knee height (3.8 +/- 1.2 mm/y), and arm circumference z scores (0.27 +/- 0.12 cm/y). Height-for-age and weight-for-age z scores decreased significantly by 0.11 +/- 0.04 and 0.13 +/- 0.05, respectively, in the control group but did not change significantly in the zinc group. Prepubertal children with SCD-SS may have zinc deficiency and may benefit from zinc supplementation to improve linear growth and weight gain.
