Effect of food supplement of humic origin on the hematological and biochemical parameters in the Cr (VI) exposed rats

Abstract

The study aimed to investigate the effect of Humilid, a biologically active food supplement, onbiochemical and hematologic parameters in the blood of rats exposed to hexavalent Chromium. Wistar male rats wereused in experiments. All animals were divided into 4 groups. Animals of experimental groups D2 and D3 received a1% solution of food supplement Humilid in a dose of 2 ml/kg of body weight during 28 days. Rats of groups D1 andD2 were injected with potassium bichromate (K2Cr2O7) in the dose of 2 mg Cr (VI)/kg of body weight from 14 days ofthe experiment. Animals of the C group were administered a 0.9% NaCl solution for 14 days. Data were analyzedusing the ANOVA test. It has been found that administration of potassium bichromate caused the cytotoxic effect onrat’s organism, inhibition of the synthetic function of the liver, hypoglycemic effect, toxic anemia and leukocytosis.The treatment with humic substances provided a marked normalization of the biochemical and hematologicalparameters in the blood of chromium-exposed animals. Biologic active supplement Humilid reduces the toxic effect ofchromium on the rat body, normalizes metabolism, and exhibits hepatoprotective and adaptogenic effects. Ourfindings show that Humilid supplementation may be helpful in the abrogation of heavy metal toxicity.
