SUMMARY :The objectives of this paper were to illustrate the distribution and levels of sediment contamination by heavy metals in the Allahabad city, and to compare recent data with those collected during the early 2001. The metals as, Cd, Ni, Cu, Fe, Pb, Co, Ni and Zn were chosen because of their abundance and toxic effects in the environment of highly industrialized and urbanized areas. The pollutants, which do not remain in water column or solution, could be absorbed rapidly by particulate matters and thereby they also could escape any detection by water monitoring schemes (Meiggs, 1980). Some heavy metals like Cd, Cu, Fe, Ni and Pb were determined in water from four reaches of the river from Yamuna (river-km 1112) upstream from Sangam to Arail Ghat (riverkm 851) downstream from Allahabad.HOW TO CITE THIS ARTICLE : Naushad, Syed Suaib, Lall, Alok Milton and Charan, Amit Alexander (2014).

The aim of this study is to evaluate the enzymatic antioxidant activity and antihyperglycaemic activity of hydroalcoholic (25:75) extract of Dillenia pentagyna Roxb. fruits. Acute oral toxicity study was carried out in healthy male Wister rats (150-200 g). The dose was finally made to 200 mg/kg and 400 mg/kg b.w. for oral administration after the LD50 estimation. The results showed that the enzymatic antioxidant of D. pentagyna were in fresh fruit extract as determined by the SOD, APX, POD, and GR assays. Oral administration of D. pentagyna extract in rat showed significant restoration of blood glucose to normal level. After 21 st day of treatment, level of blood glucose, hepatic and renal markers (ALP, SGOT, SGPT and BILIRUBIN) were significantly decreased when compared with the diabetic control. Lowering of blood glucose and other associated markers suggest that D. pentagyna extract possess potent antidiabetic activity which can be attributed to antioxidative properties in fruit extract. The findings in this study confirm the antidiabetic properties of D. pentagyna fruits which justify its traditional usage in the management of diabetes.
