Methylguanidine concentration in blood cell of nondialysed patients with chronic renal failure was quantitatively determined by the method of the present authors. We also determined tissue methylguanidine concentrations in the liver, blood cell, kidney, colon, muscle and brain of uremic rat experimentally produced by Platt's method. Methylguanidine concentrations in blood cell and tissues except the brain of the uremic rats and in blood cell of the uremic patients were 5--7 times higher than those in their serums. An increased methylguanidine concentration in the liver of the uremic rat receiving 40% protein diet was observed. These results imply that methylguanidine acts as one of the important uremic toxins in the intracellular space except for the brain, and suggest that the liver specifically affects the formation of methylguanidine.

UI MeSH Term Description Entries
D007676 Kidney Failure, Chronic The end-stage of CHRONIC RENAL INSUFFICIENCY. It is characterized by the severe irreversible kidney damage (as measured by the level of PROTEINURIA) and the reduction in GLOMERULAR FILTRATION RATE to less than 15 ml per min (Kidney Foundation: Kidney Disease Outcome Quality Initiative, 2002). These patients generally require HEMODIALYSIS or KIDNEY TRANSPLANTATION.

D008760 Methylguanidine A product of putrefaction. Poisonous.
D001806 Blood Urea Nitrogen The urea concentration of the blood stated in terms of nitrogen content. Serum (plasma) urea nitrogen is approximately 12% higher than blood urea nitrogen concentration because of the greater protein content of red blood cells. Increases in blood or serum urea nitrogen are referred to as azotemia and may have prerenal, renal, or postrenal causes.
