Comparative Study On Several Trace Element,Enzyme,FreeRadical Chemistry,CD2～+,CD14～+ Between Poll Dorset And Mongolian Sheep

Two breeds of sheep, Poll Dorset and Mongolian Sheep were used in this study. Each kind of sheep was divided into two groups: that was lamb group and young group, 30 sheep per group. There were 120 sheep.Copper Zine and Manganese in the serum and wool,Superoxide dismutase in the wool were determined by using fluorospectrophotomery and visible spectrophotofluorometry . Meanwhile, processed eosinophilicgranulocyte count test and measured the expression rate of CD2,CD14 cells by FCM.The results showed that: The levels of Cu,Zn,Mn,T-SOD,CuZn-SOD,Mn-SOD in the serum and wool of Poll Dorset were significantly lower than that of Mongolian Sheep ,The effect of season and breed was marked difference(p<0.001); The activity of OH-. in serum samples of Poll Dorset was significantly higher than that of Mongolian sheep,The effect of season and breed was marked difference(p<0.001);For the same breed,young and adult sheep,the activity of T-SOD Mn-SOD and OH-. in the serum were marked difference(p<0.001),The basic disciplinarian for the activity of T-SOD and Mn-SOD. in serum was that adult sheep was the highest and lamp sheep was the least,For the activity of OH-. in the serum,young sheep was the least.The experiment proved that the levels of Cu,Zn and Mn in the seram and wool,the activity of T-SOD,CuZn-SOD,Mn-SOD,OH-.and CD2+,CD14+ in serum samples,those maybe one of the reasons that the susceptibility of disease of Poll Dorset was higher than that of Mongolian sheep under the same conditions.There was interrelated between the levels of Cu,Zn,Mn and the activity of CuZn-SOD,Mn-SOD in the serum。...
