in order to better characterize the pathogenesis of alpha 2u-globulin ( alpha 2ug ) nephropathy , cell proliferation was quantitated within the three proximal tubule segments of the kidney ( p1 , p2 , and p3 ) and proximal tubule segments affected by chronic progressive nephrosis ( cpn ) in male and female f344 rats exposed to 10 , 70 , or 300 ppm unleaded gasoline ( ug ) or 50 ppm 2,2,4-trimethylpentane ( tmp ) from 3 to 50 weeks .
