Abstract:

The renal corpuscles of desert deermice and swamp deermice were investigated for quantitative differences in structure by statistico-geometrical stereological methods. There was found to be essentially no difference between the two groups in mean glomerular size. Blood channel length per unit glomerular volume in swamp mice was found to be 1.09 times that of desert mice. Filtration surface area per unit glomerular volume in swamp mice was found to be 1.25 times that of the desert mice. However, these relatively small differences between individual glomeruli were greatly magnified by a 1.6-fold difference in the number of glomeruli per kidney in swamp mice 13,700 over desert mice 8,600. As a result, the blood channel length per kidney in swamp mice 23 meters was 1.77 times that in desert mice 13 meters, and filtration surface area per kidney in swamp mice 430 mm sq. was found to be 2.05 times that of desert mice 210 mm sq..
