TI: Ozone-Oxygen Therapy in Proctology DT: 1990 AU: Knoch HG., Klug W. SO: Terapevticheskii Arkhiv 62(2):98-8, 1990 AB: The diffusion of oxygen through the colon wall could be demonstrated in animal experiment. The relevant rise in PaO2 can be evidenced in both in blood vessels and in the liver, whereby a significantly high increase of 250% above the normal value was recorded in the region of the intestinal wall. The venous blood values were at 230%, those in the portal vein at 134%, and in the liver parenchyma at 127%. When ozone is applied, these values are even higher. An increase can also be recorded in humans by means of transcutaneous PaO2 measurements. In proctology, we view the indication of rectal insufflation to be valid for colitis. The present report covers initial results and experience: a further short report on the possibility of treating hepatitis in the same way will be following.
