Effect of Emblica officinalis fruits against metallic-lead induced biochemical and hematological alterations in Wistar rats
Lead toxicity and related health issues have become global concern due to increased use of lead-based products in the modern world. Though attempts are being made to tackle this malady through many ways, the use of naturally occurring materials that are available locally is a subtle approach. In this investigation, the fruits of E. officinalis (EO) were studied for their potential in overcoming biochemical and hematological alterations caused by metallic lead in rat model. Four groups of rats, each containing six animals, were considered for the study. Group I served as normal control while to other groups (II– IV), metallic lead powder (100 ppm/rat) was orally administrated for 30 consecutive days. From day 31, the animals in groups III and IV were treated with EO in doses of 50 and 100 mg/kg body weight (p. o.), respectively, for the following seven days. Group II served as lead-treated control. On day 38, the animals in all groups were sacrificed and the blood was collected and serum separated. The changes in biochemical (aspartate aminotrasferase, alanine aminotrasferase, alkaline phosphatase, gamma glutamyltrasferase, total cholesterol, triglycerides, urea, creatinine and calcium) and hematological (red blood cell count, white blood cell count, hemoglobin, packed cell volume and platelet count) parameters were estimated. Lead treated animals in Group - II showed appreciable changes in hematological and biochemical parameters. Treatment with EO (50 and 100 mg/kg) significantly restored the changes in the above parameters to near normal values implying that the fruit of E. officinalis is an effective natural material to overcome widespread lead toxicity. This observation is further supported by histopathological studies of liver and kidney tissues wherein the distorted architecture, degeneration and other changes found in lead-treated animals were brought back to near normal stages by the treatment of EO
Moringa oleifera seeds attenuate benzene-induced alterations in lipid peroxidation and antioxidant enzymes in liver and kidney tissues of Wistar rats
Benzene is a notorious toxicant that is responsible for a host of diseases including leukemia. Its concentration in the environment is increasing day-by-day due to excessive automobile use, accelerated industrial activities and cigarette smoke. The awareness on the harmful effects of benzene on health is limited and no antidote has been reported yet. In this study, an attempt has been made to find out a suitable remedy to overcome benzene toxicity in a living organism from a natural source with the seeds of the plant Moringa oleifera (MO). Thirty six Wistar rats were considered for the study and divided into six groups (n=6). While group I remained as control with normal animals, those in groups II – VI received benzene by oral route (800 mg/kg body weight) for 28 consecutive days. On day 29, the benzene-treated animals in groups III – VI received respectively the standard drug ascorbic acid (AA, 25 mg/kg body weight) and MO (50, 100 and 200 mg/kg body weight) for the following 7 days. Group II rats that received only benzene served as negative control without any treatment. On day 36, all the animals were sacrificed and vital organs liver and kidney were removed for studying lipid peroxidation (LPO) and antioxidant markers [Superoxide dismutase (SOD), Total reduced glutathione (TRG), Glutathione peroxidase (GPx) and Catalase (CAT)] in addition to histopathological changes in the tissues. The results of the study revealed that significant changes occurred in the above parameters due to benzene dosing to animals were reverted to near normal values on MO administration in the liver and kidney tissues as compared to untreated animals, suggesting MO’s pro-active role in attenuating benzene toxicity
