Objective: To evaluate the ameliorating effects of Raphanus sativus leaves (RSL) against sodium arsenite(Sa)-induced adverse effects through mice experiments. Methods: Swiss albino mice were divided into four equal groups: control, Sa, RSL, RSL + Sa. Sa (10 mg/kg body weight/day), and powder form of RSL (50 mg/kg body weight/day) were provided as food supplement orallty. Blood indices were measured using commercially available kits through colorimetric methods. Results: It was observed that lactate dehydrogenase, alkaline phosphatase, alanine aminotransferase,and aspartate aminotransferase activities were significantly(P<0.05) higher in Sa-treated mice than those in the control group.RSL significantly reduced Sa-induced elevation of the activities of these enzymes in serum significantly (P < 0.05). Serum butyrylcholinesterase activity and high density lipoproteins cholesterol levels in Sa-treated mice were significantly (P < 0.05) lower than the control group, and the food supplementation of RSL could significantly(P<0.05)prevent the reduction of Sa-mediated serum butyryl cholinesterase activity and high density lipoproteins cholesterol levels.RSL could also reduce the Sa-induced elevation of serum urea level significantly(P<0.05). Conclusions: Results of this study suggest the protective or ameliorating effects of RSL on Sa-induced perturbation of blood indices are related to the hepatic,cardiovascular and kidney dysfunction.Therefore,RSL may be useful to reduce arsenic toxicity in human in the future.

Objective: To evaluate the toxic effect of hydrose used in the molasses preparation in Bangladesh. Methods: Molasses were collected from open markets in different parts of Bangladesh. The presence of hydrose in selected molasses was detected using commercial kit. To evaluate the toxic effect of hydrose, Swiss albino male mice were divided into four groups. Group I was used as control, while Groups II, III and IV received hydrose mixing food (5, 10 and 25 g/ kg food), respectively, and these supplementations were continued to the end of the study (16 weeks). Blood was collected from thoracic arteries of the mice under ether anesthesia and then organs were taken. To determine the effect of hydrose on host, blood indices related to liver, heart and kidney dysfunctions were measured. Result: Creatinine and urea levels were significantly (P < 0.05) increased in a dose dependent manner in hydrose treated mice, whereas calcium level was significantly decreased in hydrose exposed mice compared to control mice. Histological study of kidney showed the glomeruler inflammation, increased diameter of renal glomeruli and enlargement of proximal tubular lumen of kidneys of mice exposed to hydrose compared to that of control animals. Conclusion: The results of this study indicated that use of hydrose in molasses and other food preparations in Bangladesh may cause kidney impairment.
