ABSTRACT
Objective: To investigate the combined preventive effect of folic acid (FA) and vitamin B12 (VB12) on the developmental toxicity of alcohol. Methods: To build animal model with the developmental toxicity by giving 5g/kg bw alcohol (25% ethanol) intragastrically (IG) to ICR mice during gestational day (GD) 6-15. In addition to alcohol, three groups were given FA 60 mg/kg bw, VB12 1 mg/kg bw, FA 60 mg/kg bw + VB12 1 mg/kg bw respectively by IG during GD1-GD16. An alcohol model group and a negative control group were set. All dams were killed at GD18. Results: Compared to the alcohol model group, the pregnant mice of FA + VB12 combined intervention group put on more weight during pregnancy; the live fetal rate; the fetal weight, body length and tail length were all increased; the abnormal ossification rate of sternum, occipital bone, and four limbs dropped (P
ABSTRACT
Objective: To explore the effects of multivitamin and mineral supplements on self-evaluation of mood and health status in healthy volunteers.Methods:149 healthy volunteers took multi-nutrient supplements or placeboes for 8 weeks, and self-evaluation of mood and health status was evaluated by Profile of Mood States and 36-item short-form health survey.Results:Self-comparing POMS scores, active group's scores of vigor were significantly increased, from 14.2? 4.6 to 15.5 ? 4.9(t=2.74,P37)were significantly improved. But the placebo group and young volunteers were not significantly improved. Conclusion: The intervention of multivitamin and mineral supplements can improve elderly healthy persons' mood and healthy status.
ABSTRACT
Objective: To observe the effect of vitamin A and iron supplementation on iron status during pregnancy. Methods: 167 pregnant women aged 21～33 years in the second trimester were recruited and randomly allocated to four groups: placebo; vitamin A (1.1 mg/d); iron(60 mg elemental iron); vitamin A and iron, for 10 weeks. Results:The incidences of vitamin A deficiency, anemia and iron depletion were 0.6%,7.8% and 6.2% in the second trimester respectively. Serum VA level was not changed in three supplemented groups but decreased in placebo group. Hemoglobin in all groups before and after supplementation was in normal range, with no significant differences. The improvement in serum ferritin, free erythrocyte proporphyrin and transferrin saturation was better in the group supplemented with VA+Fe than VA or Fe alone. Conclusion: The simultaneous supplementation of vitamin A and iron is better in improvement of iron status than supplementation of vitamin A or iron alone during pregnancy. Improvement of iron status by simultaneous supplementation of pregnant women with vitamin A and iron was better than supplementation with iron or vitamin A alone.
ABSTRACT
Weight gain, skinfold thickness, circumference and body density were measured in 30 primiparous women aged from. 23-31 years (averaged 26.3 years old).The average body weight gained 13kg from 6 to 37 weeks of pregnancy.The suprailiac skinfold thickness in 24-37 weeks and the subscapular skinfold thickness in 37 weeks increased significantly from the 6th week of pregnancy, but the triceps and biceps skinfold thickness did not change significantly. The density of the body in 24th and 37th week of pregnancy decreased significantly.The change and the body fat (%) calculated by means of 4 skinfolds increased in 3.7% (5.7kg of fat). The mean values of the hip circumference in 24th and 37th week were significantly different from that in 6th week of pregnancy. The upper thigh in the 24th and 37th week also increased slightly but not significantly different as compared with the 6th week. The mean values of arm, mid-thigh and calf circumference did not change during pregnancy.
