[Glomerular filtration rate in distinct nephron populations of rodents with different ecological specializations].
14C-ferrocyanide studies of glomerular filtration rate (GFR) distribution among different nephron population has shown that in Arvicola terrestris after dehydration the GFR is increased in juxtamedullar nephron in comparison with superficial ones, while in homozygote rats of Brattleboro line no similar changes of GFR distribution between distinct nephron population took place. In Rhombomis opimus the GFR after dehydration was usually greater in juxtamedullary nephrons. These results indicate the necessity of vasopressin for GFR regulation in distinct nephron populations.
