Abstract

BACKGROUND Lead acetate inhibits pyrimidine-5’-nucleotidase resulting in ribonucleic acid and ribosome accumulation in erythrocytes (RBC), visible as basophilic stippling (BS). Lead exposure disrupts RBC membrane, shortens the RBC life span and decreases hematocrit. Zinc supplementation increases lead-binding proteins (metallothioneins). The study objective was to determine whether zinc supplementation prior to lead exposure decreases BS and increases the hematocrit in rats. METHODS The study was a randomized post-test only control-group trial, using 28 rats allocated to one control and 3 intervention groups (Zinc I, Zinc II, Zinc III) receiving 0.2 mg, 0.4 mg, and 0.8 mg of zinc by oral gavage daily for 3 weeks. All groups were then exposed to lead at 0.5 g/kg BW/day by gavage for 10 weeks. On the last day of the 10 weeks BS was determined from Giemsastained blood smears and hematocrit by hematology analyzer. Between-group differences were tested with one-way ANOVA, followed by Bonferroni’s test. RESULTS Mean BS was significantly decreasing 7.93 ± 0.99% in controls, 6.91 ± 1.04%, 4.66 ± 0.79%, and 1.73 ± 0.88%, respectively, in intervention groups (p=0.000). Mean hematocrit was significantly increasing 26.16 ± 3.60% in controls, and 30.33 ± 6.12%, 36.83 ± 3.31%, and 40.00 ± 4.77%, respectively, in intervention groups (p=0.000). One-way Anova and Bonferroni’s test showed significant differences in BS and hematocrit between controls and intervention groups receiving zinc supplementation of 0.4 and 0.8 mg (p=0.000). CONCLUSION Zinc supplementation before lead exposure significantly decreases basophilic stippling and increases hematocrit level in rats exposed to lead

Abstract

BACKGROUNDLead acetate may inhibit the enzyme aminolevulinate dehydratase (ALAD) resulting in decreased heme synthesis (and consequently in anemia) but in increased number of reticulocyte cells. IR Bagendit paddy leaf water extract has a high metallothionein protein content which acts to bind to lead. The study objective was to determine whether aqueous IR Bagendit rice leaf extract dosage variations prior to lead exposure decreases reticulocyte count in lead-exposed rats. METHODSThe study was of randomized post test only control-group design involving a sample of 28 rats, that were randomized into 4 groups consisting of 1 control group and 3 treatment groups, daily administered with aqueous IR Bagendit rice leaf extract of respectively 0.2; 0.4; 0.8 mg using a feeding tube up to week 13. Lead exposure was also given using a feeding tube to both control and treatment groups at a dose of 0.5 g/kg BW/day, up to week 13. The reticulocyte count was then examined using supravital brilliant cresyl blue staining. The reticulocyte count was determined per 1000 erythrocytes and then converted into a percentage. Kruskal Wallis test followed with Bonferroni test was conducted to figure out the differences between groups. RESULTSMean reticulocyte count decreased significantly, starting from the control group up to the third treatment group (15.48 ± 3.41; 12.25 ± 03.28; 10.45 ±1.47; 9.10 ± 2.35 average per unit) (p=0.02). The Bonferroni test showed that the reticulocyte count was significantly decreased in the third treatment group (p=0.004). CONCLUSIONAqueous rice leaf extract significantly decreases reticulocytes in rats exposed to lead.
