renal/urinary system
N
• at 9-10 weeks of age, kidney weight, cortical tubule diameter, and Bowman's space diameter remain normal
• renal blood flow is significantly reduced
• total renal vascular resistance is significantly increased
• fractional excretion of sodium is significantly reduced
• urinary osmolality is significantly increased
• urinary albumin excretion is significantly elevated
• Bowman's capsule diameter is significantly reduced
• however, Bowman's space diameter remains normal
• glomerulus tuft diameter is significantly reduced
• however, no glomerular hypertrophy is observed
• increased expression of collagen IV and fibronectin in the mesangium
• however, normal expression of collagen types I and III in the mesangium
• increased expression of collagen III, collagen IV, and fibronectin in the renal interstitium (cortex and medulla)
• however, normal expression of collagen I in both cortex and medulla
• creatinine clearance is significantly increased
• GFR is significantly elevated (1.8-fold), as measured by creatinine and inulin clearances
• 24-h urine flow is significantly reduced

homeostasis/metabolism
N
• Background Sensitivity: no differences in blood glucose levels are observed on a C57BL/6 background
• plasma osmolality, osmolal, and free-water clearance are normal
• fractional excretion of potassium is normal
• fractional excretion of sodium is significantly reduced
• urinary osmolality is significantly increased
• urinary albumin excretion is significantly elevated

cardiovascular system
N
• Background Sensitivity: mean arterial pressure is normal on a C57BL/6 background
• renal blood flow is significantly reduced
• total renal vascular resistance is significantly increased

behavior/neurological
N
• no differences in water and food intake are observed
