Is glomerular arginine transport attenuated in chronic renal failure in rats?
glomerular arginine uptake is decreased in CRF. This phenomenon can explain the beneficial effect of L-arginine supplementation in CRF.
PAAs showed more signs of previous intramural hemorrhages compared with AAAs. In addition, inflammation in PAAs is mainly located in the intima, whereas its focus in AAAs is the adventitia. These results suggest important differences in the pathophysiologic mechanism of aneurysm formation between these locations and might explain the differences in presentation on diagnosis.
