strain_life_disease Hypertension and vascular and renal lesions do not develop on a high (8%) salt diet (cf SS, see for example, Pontremoli et al, 1992). Mild hydronephrosis at 4 months of age that is probably genetically determined (Rapp and Dene 1985). Has mutant form of cytochrome P450(11-beta)(Matsukawa et al, 1993). Has lower transepithelial, unidirectional, sodium flux than SS and Sprague-Dawley which may be associated with its resistance to the development of hypertension on a high salt diet (Kudo et al, 1994). 61037
