Subject: Why is there so much catalase in the kidney?

I did an experiment where I liquidised 100g of liver, muscle, kidney and heart 
and mixed each of them with 1 litre of distilled water. Then I added hydrogen 
peroxide and measured the amount of oxygen produced.  I found that the most 
oxygen was produced from the liver mixture but  large amount was produced from 
the kidney. I have been searching on the internet for hours to find out why 
there is so much catalase in the kidney but it only tells me about the liver. I 
have already read the question about catalase posted by Kumar Chandraskharan on 
Mon Sep 28 23:13:55 1998 but it doesn't answer my question about the amount of 
catalase in the kidney. I would really appreciate it so much if you would be 
able to answer my question because I really can't find the answer anywhere.
Thankyou
