| Abstract | ||
| The research was conducted to study the effect of cadmium on some biochemical aspects of adult earth worms Aporrectodea caliginosa used for this perpuse five concentrations of cadmium which 1 , 3 , 5 , 7 , 9 ppm in addation to the control group . The worms were adminstrate with mentioned cadmium concentration for 14 days , then determined the leathal concentration and half leathal concentration . Also determined the biochemical effects by determine the proteins , transferases and alkaline phosphatase . Also determined the nature of protein bands by poly acrylamide gel electrophoresis . The results was : 1. The leathal concentration was 9 ppm while the half leathal concentration was 7 ppm . 2. Occur significant decrease in soluable protein concentration (p<0.05) in earth worm extraction compare with control group , at all study cadmium concentration 3 , 5 , 7 ppm , when used electrophoresis method for proteins show change in protein bands disappear some bands and increase density of some and decrease density of others. 3. Occur significant increase (p<0.05) in Alanine Aminotransferase , Aspartate Aminotransferase and Alkaline phosphatase compare with control at all study cadmium concentrations . | ||
