 · Kf = ultrafiltration coefficient, GFR = glomerular filtration rate, AT-II = angiotensin II, NO = nitric oxide. Vascular permeability The asymmetric expansion of the interstitial volume in NS is explained by changes in intrinsic properties of the endothelial capillary barriers , including its increased hydraulic conductivity and permeability to proteins, rather than to an imbalance of the

Inulin is used as an indicator of glomerular filtration rate? …

 · Inulin is used as an indicator of glomerular filtration rate because it is freely filtered and not reabsorbed. Plasma inulin concentration is 1mg/ml; plasma glucose is 1mg/ml; inulin excretion rate is 100mg/min and glucose excretion rate is 0mg/min. Determine GFR.
