The effect of acute <i>in vivo</i> administration PF and SF PAMAM dendrimers on morphological changes in non-diabetic and diabetic rat kidneys.

Key: Morphology was graded as either (0) none, (+) mild, (++) moderate or (++++) severe. $GS: diffuse glomerular sclerosis; EX: extracelluar matrix deposition (or interstitial fibrosis); FTI: fibrosis in tubulointerstitium; HPAS: hyperplastic arteriolosclerosis; IIVCIH: intensity and incidence of vacuolations, cellular infiltration and hypertrophy.
