Therapy Effects of Ozonized Oil (Oleozon) in the Treatment of Giardiasis F. Piñol, N. Cedeño, W. Díaz. Giardia lamblia is a cosmopolite protozoan that, nowadays, creates serious problems of health because of the amount of symptoms that accompany its infection. Fifty patients from 17 to 55 years old suffering of giardiasis were studied. The diagnosis was confirmed by duodenal gavage or stool. The patients received daily 2 capsules of OLEOZON of 1 mL each (one in the morning and one in the night) during 10 days. Afterwards, stop treatment for 1 week and repeat the cycle the same as the first one. As healing criterion, the absence of cysts or trophozoites of Giardia lamblia, in a sample of duodenal superficial tissue under endoscopic sight, was considered. The results demonstrated that there was 67 % of parasitologic healing and 85 % of improvement in the inflammatory process that accompanies this disease (gastritis, duodenitis).
