We injected 0.3 ml. of polytetrafluoroethylene paste (Polytef) behind the left submucosal ureter in 4 mini-pigs and 4 dogs, and 2 dogs and 2 mini-pigs underwent sham operation and acted as controls. Two mini-pigs were injected with 0.5 ml. polytetrafluoroethylene (Teflon) suspended in 50 ml. of normal saline into a peripheral vein and 2 dogs were injected with 0.5 ml. polytetrafluoroethylene into a bladder vein. In addition, 4 dogs were injected with 0.1 ml. polytetrafluoroethylene paste suspended in 20 ml. saline into the right carotid artery. The lungs and brain from half of the animals who had subureteral and intravascular injection of polytetrafluoroethylene paste as well as sham operated animals were dissolved in sodium hypochlorite solution. The resulting organ suspensions were then centrifuged and the smear preparations of the precipitate were examined by polarized light microscopy, scanning electron microscopy and x-ray microanalysis. Polytetrafluoroethylene paste suspended in saline acted as positive control for polytetrafluoroethylene particles. Lungs and brain from the remaining animals were fixed in formalin solution. The brain and lungs of animals who underwent subureteral injection with a minimal amount of polytetrafluoroethylene paste carefully placed in the submucosal plane showed no evidence of polytetrafluoroethylene on histological examination, polarized light microscopy, scanning electron microscopy and x-ray microanalysis.

The action of indirect electrochemical blood oxidation with 0.06% solution of sodium hypochlorite on kidney and urinary inflammation was studied in experiments on 60 non-inbred rat females of 200-250 g body weight. The animals were intravesically infected through the catheter with E. coli and Ps. aeruginosa. 3 days later, after histological verification of acute pyelonephritis, ureteritis, cystitis, the animals were injected intraperitoneally 1.0 and 2.0 ml daily of sodium hypochlorite solution (control animals) or 0.89% solution of sodium chloride. Though no reliable decrease of the bacterial contamination was achieved, histologically, there was a marked reduction in morphological signs of the inflammation in the kidneys, ureter and urinary bladder on the first day after beginning of electrochemical blood oxidation with solution of sodium hypochlorite in experimental groups. In experimental group rats morphological signs of urinary and renal inflammation for both infections disappeared on days 7 and 10, respectively. In the control animals morphological signs of the inflammation remained after 10 days. Moreover, purulent inflammation was registered in the controls infected with Ps. aeruginosa.
