albuminuria
(
J:160943
)
• urine albumin excretion is increased 140% by 26 weeks of age
|
• glomerular basement membrane thickness is increased by 8%
|
• glomeruli have diffuse mesangial expansion, occasionally with nodular features
• mesangial matrix accumulation consists of excess type IV collagen and fibronectin
• type IV collagen is increased by 57%
• glomerular fibronectin is increased by 100%

• mean capillary diameter (MCD) is increased by 44%
• glomerular celllularity is decreased by 16%
|
• lesions progress to a moderate severity by 26 weeks of age
|
• kidney weight/body weight ratio is reduced 20% by 26 weeks of age compared to controls
|
• mice have 23% fewer cortical renal tubules/unit area
|
homeostasis/metabolism
• plasma creatinine concentration is increased 25% at 26 weeks of age
