Abstract

Oral  administration  of  ozonized  sunflower  oil  to  Wistar  rats  has  produced  changes in the urinary content of dicarboxylic acids. Heptanedioic acid (Pimelic acid) and nonanedioic acid (Azelaic acid) were the major increased dicarboxylic  acids founded. The aim of this work is the study of the urinary dicarboxylic acid profiles of Wistar rats, orally treated with ozonized standard triglycerides. The dicarboxylic acids were extracted and derivatized before the analysis by Gas Chromatography – Mass Spectrometry. The urinary dicarboxylic acid profiles of the  rats  that  received  ozonized  triolein,  only  showed  the  increasing  of  heptanedioic and nonanedioic acids. However, when ozonized trilinolein was applied, the profile is similar to that obtained, when ozonized sunflower oil was administered. A biochemical mechanism to explain the formation of dicarboxylic acids from ozonated unsaturated triglycerides was proposed.

Introduction

Ozonized  Sunflower  Oil     (OLEOZON®)  is  a  registered  drug  that  has  shown antimicrobial effects against virus, bacteria and fungi (Cajigas et al., 1990; Lezcano et al., 1996;  Lezcano  et  al., 1998).  On  the  other  hand,  toxicological  studies  of OLEOZON® have demonstrated that this product is not mutagenic or genotoxic and has not secondary reactions in human patients (Llerena et al., 1995; Martinez et al., 1995; Remigio et al., 1998). Since 1994 it has being studied the use of ozonated sunflower  oil  in  the  treatment  of  giardiasis  in  animal  models  and  in  humans (Menéndez et al., 1995; Hernández, 1999).

Oral administration of ozonized sunflower oil to Wistar rats has produced changes in the urinary content of dicarboxylic organic acids (Jardines et al., 1998). An increment in urine of heptanedioic, octanedioic, octenedioic, nonanedioic, decenedioic and dodecanedioic acids has been observed. Heptanedioic acid (Pimelic acid) and nonanedioic acid (Azelaic acid) were the major increased dicarboxylic acids founded.
