although in vitro and in vivo studies have suggested that the glomerular effects of aii may be associated with contraction of glomerular mesangial cells , recent in vivo quantitative evaluation has suggested that a uniform vasoconstriction of glomerular capillaries with proportional reductions in glomerular surface area is probably not the sole mechanism for the aii-induced reductions in glomerular ultrafiltration coefficient .
