We studied the effects of intravenous anesthetics ketamine and propofol on rat mesangial cell (MC) proliferation. Ketamine inhibited [3H]tymidine incorporation into the mesangial cells in a concentration-dependent manner (10 mM*1 mM). But, Propofol had no effects on [3H]tymidine incorporation. Ketamine also attenuated the cell number at clinical concentrations and increased cAMP levels in MC.Protein Kinase A inhibitor recovered the inhibition of ketamine on MC proliferation. Ketamine kept the renal blood flow in Rat in vivo. These results suggested that ketamine have inhibitory effects on the MC proliferation via protein kinase pathway and ketamine may be useful to suppress the progression of chronic renal failure.
