Folic acid contents of plasma, whole blood, liver and spleen in Rauscher leukemic mice were estimated. Plasma and liver folate in the leukemic mice was lower than that of normal mice, suggesting that folic acid was deficient in Rauscher leukemia. Folic acid contents in whole blood and spleen were even higher in the leukemic mice than those in normal mice. Clearance study by injecting folic acid...

A high incidence of subnormal serum folic acid levels was observed in 48 patients receiving anticonvulsants (75 %). In peripheral blood, macrocytosis was detected in 46 % and an increase of hypersegmented neutrophils was also seen in 24 % of the patients. Correlation existed between these signs and low serum folate levels. The growth response of Lactobacillus casei and L. leichmannii was not su...

L-tyrosine, B6 and folic acid are involved in biosynthesis of DOPA and consequently dopamine. The aim of this study was to investigate the antiparkinsonian effect of these agents in perphenazine-induced catatonia in rats. Murprogo method or scored muscular rigidity, which is induced by a phenothiazine, was used to evaluate the antiparkinsonian effect of these agents. A significant decrease in m...

Development of an easy, inexpensive, fast and selective spectrophotometric method for the determination Folic Acid (FA) by its reaction with 4-nitro aniline reagent, good sensitivity, as oxidative coupling in presence Potassium permanganate solution, it was found that concentrations were agreement Beer-Lambert’s law at wavelength 374 nm ranged between 1- 21 µg/ml folic acid a deviation from Bee...

Objective(s)Previous studies have shown that vitamin B as well as folate supplementation has been implicated in cognitive and neurodegenerative disorders including Alzheimer’s and Parkinson's diseases. The aim of present study was to evaluate the effects of folic acid on passive avoidance task and motor coordination in healthy adult male rats.Materials and MethodsAnimals were randomly divided i...

OBJECTIVES To evaluate the effects of folic acid supplementation on isolated oral cleft recurrence and fetal growth. PATIENTS AND METHODS The study included 2,508 women who were at-risk for oral cleft recurrence and randomized into two folic acid supplementation groups: 0.4 and 4 mg per day before pregnancy and throughout the first trimester. The infant outcome data were based on 234 live bir...

BACKGROUND Folic acid can prevent up to 70% of neural tube defects (NTDs) if taken before pregnancy. Compared with other race-ethnicities, Hispanic women have higher rates of NTDs, lower rates of folic acid supplement use, and lower total folic acid intakes. OBJECTIVE The objective was to assess potential effects of fortifying corn masa flour with folic acid on Mexican American women and othe...

OBJECTIVE To examine the impact of antenatal supplementation with multiple micronutrients or iron and folic acid compared with folic acid alone on birth weight, duration of gestation, and maternal haemoglobin concentration in the third trimester. DESIGN Cluster randomised double blind controlled trial. SETTING Two rural counties in north west China. PARTICIPANTS 5828 pregnant women and 46...

Folate, a water-soluble B vitamin, is a cofactor in one-carbon metabolism and is essential for DNA synthesis, amino acid interconversion, methylation and, consequently, normal cell growth. In animals with existing pre-neoplastic and neoplastic lesions, folic acid supplementation increases the tumour burden. To identify processes that are affected by increased folic acid levels, we compared HT29...
