Abstract:
Objective To understand the effect of vanadium to liver ultramicro structure in SD rats.Methods One hundred and fifty generaMevel SD rats of 2 months were randomly divided into control groups,30 in each,the males and females were equivalent,treated with ammonium metavanadate at doses of 0,10,20,40,60 mg/L through drinking water.After 2,6 and 10 weeks of treatment,6 rats from each group were weighed and the changes of ultramicro-structure in the liver were examined with electron microscope.Results As the increasing of dose,the increase in body weight showed a downward trend,but the coefficient of liver showed a increasing trend,the consistent performance was seen in male and female rat.After two weeks of exposure,the rats acted,ate and drank less,hair roughing and no shining,often getting together were seen.After 10 weeks,the rats had not the basic activities,the hair was disheveled and loose,some died,the structure of mitochondria and endoplasmic reticulum was normal in the 10,20,40 mg/L group,the number of endoplasmic reticulum increased,in 60 mg/L group,the rough endoplasmic reticulum vanished,the liver cytoplasm had a swelling phenomenon,the mitochondria reduced.Conclusion Vanadium have little effect on the liver cells of rats in low exposure level,but high level exposure may damage the liver cells in rats.
