ABSTRACT
Ozone therapy is presented like an alternative therapy in critically ill patients. After ozone therapy, an improvement in the hemodynamic parameters with an increase in tissue oxygenation were demonstrated. No modifications in the cardiac output were reported. A modulating effect of ozone therapy in certain biochemical parameters was observed. Also, microbiologic cultures were negative and leukocyte figure became normal. An ozone therapy preventive effect in the appearance of generalized sepsis was observed. With all these results we conclude that ozone therapy can be considered as a prophylactic therapy in critically ill patients.

192 Wistar male rats (180 - 200 g) were used to evaluate the prophylactic effect of ozone combined with antibiotics in septic shock model. The proinflammatory cytokines (IL-1b, TNFa, IL-6 and IL-2) expression were also determinated in different haemathopoyetic organs. The animals were taken at random and divided into 16 groups, 12 animals each: Group A, positive control (sepsis without treatment); groups B and C treated with ozone (200 mg / 250 g b. w) and Cefotaxim (25 mg/kg), (0h, +1h) and (+1 h) respectivitly; groups D and E, ozone and Cefodizim (25 mg/kg (0h, +1h) and (+1 h) respectively; groups F and G ozone and levofloxacin (12.5 mg/kg), (0h, +1h) and (+1 h) respectively; groups H and I ozone and Piperacillin /Tazobactam (65mg/kg), (0h, +1h) and (+1 h) respectively. The septic shock was carried out by single intraperitoneal injection of fecal material (0.65 g/kg b/w) from a donor rat, diluted in saline solution 0.9 %. The other groups (J-P) of animals were treated only with antibiotics.
The group pretreated with ozone and antibiotics showed a significant increase in the survival rate and showed also a decrease of IL-1b mRNA expression in liver. Ozone pretreatment might prevent lethal peritonitis by controlling inflammatory process generated physiologically into the body against specific damage or specific organism

It has been demonstrated that ozone, probably by means of an oxidative preconditioning (OP) mechanism, protected the liver against the damage mediated by reactive oxygen species. Taking into account that ischemic preconditioning (IschP) is also a protective mechanism, a comparative study between both preconditioning effects, with the aim to study the effectiveness of both protective procedures, was performed. Rats were divided at random in: 1- control, sham operated (anesthesia and laparotomy plus surgical manipulation); 2- I/R (ischemia for 90 min followed by 90 min reperfusion); 3- IschP + I/R, as group 2 but submitted to a previous ischemic preconditioning (ischemia 10 min and reperfusion 10 min); 4- OzoneOP + I/R, as group 2 but submitted to a previous oxidative preconditioning with 15 sessions, daily, of ozone by rectal administration (dose = 1 mg/kg). The comparison between both preconditionings showed no biochemical differences for the parameters evaluated. Nevertheless, the histological study demonstrated that the protective effect produced by the OzoneOP is superior to that achieved with the IschP.

New version of "Information help system for ozone therapists" is in testing state!
