Resumen
El Ozono con su gran poder oxidante es capaz de reaccionar con moléculas biológicas importantes que se encuentran en el torrente sanguíneo, de los de las que se encuentras los fosfolípidos de membranas, de esta forma se producen sustancias oxidadas tales como lípidos oxidados capaces de ejercer efectos terapéuticos importantes, dentro de los que se encuentra el restablecimiento del balance antioxidante /proxidante y de esta forma modular la respuesta inflamatoria. Con el objetivo de evaluar el posible efecto tóxico que puede producir el ozono aplicado por la vía autohemo, se emplearon en el estudio ratas hembras y macho de la línea SD, los que fueron divididos en cuatro grupos experimentales de 16 animales cada uno (8 animales de cada sexo). Grupo I, recibe tratamiento con oxigeno; grupo II, tratado con ozono (21,12 μg/mL), dosis 168 µg/kg; grupo 3, tratado con ozono (47,04 μg/mL, dosis 376 µg/kg; grupo 4, tratado con ozono (64,16 μg/mL, dosis 512 µg/kg. Para la aplicación del ozono se le extraen a cada animal 2 mL de sangre la cual es mezclada con 2 mL de ozono a la concentración anteriormente descrita para cada uno de los grupos, esta mezcla es inyectada por la vena de la cola, este tratamiento se realizó una sola vez. Posteriormente los animales fueron observados durante 14 días, donde se registrados sus signos clínicos, peso corporal. Al final del estudio se les practica la eutanasia y se realizó la inspección anatomopatológica de los órganos. Se obtuvo como resultado el comportamiento normal de los animales y la no evidencia de signos de toxicidad, por lo que se concluye que las dosis de ozono aplicadas por vía autohemo, no fueron tóxicas.

Abstract
Assay of Ozone Acute Toxicity Applied by Autohemotherapy to Rats.
Ozone (O3) with its great oxidant power is able to read with biological molecules which are available in the blood such as membrane phospholipids and in this way are produced oxidized substances which are able to produce therapeutic effects, such as to restore the antioxidant/prooxidant balance and in this way modulate the inflammatory response. With the aim in order to evaluate the potential toxic effect of O3 applied by autohemotherapy, male and female SD rats were used, which were divided in four experimental groups of 16 rats (8 per each sex). Group 1 received treatment with Oxygen, group2 treated with O3 (21.12 μg/mL, doses 168 µg/kg); group 3, treated with O3 (47.04 μg/mL, doses 376 µg/kg); group 4, treated with O3 (64.16 μg/mL, doses 512 µg/kg). For O3 application, 2 mL of blood which are mixed with 2 mL of O3 to the concentration before described for each group. This mixture is injected by the tail vein only once. Thereafter the rats were observed during 14 days and were registered the clinical signs and body weight of the rats. Thereafter, the rats were killed and the state of the organs was evaluated. The rats showed a normal behavior and no signs of toxicity were found. In conclusion, we found that applied O3 does by autohemotherapy were non toxic.
