In the mechanism of the biological action of ozone there are many obscure questions concerning its immediate influence on the nervous tissue. The aim of this research is to study, in experimental conditions, the influence of an ozonized solution containing middle therapeutic concentration of ozone in the somatosensory caused potential (SP), in the enzyme activity of the aerobic metabolism and in the contents of peroxidation lipid products in a somatosensory zone of the cortex in cats brain.
The registration of the caused potential was made on an open brain of 13 adult cats which received intraperitoneal nembutalo-chlorosoli narcosis. With this purpose an electrical boring rendered branches of the radial nerve in the area of the wished joint. Consecutive application of nonozonized and ozonized solution was carried out. In subsequent, the site of the brain was exposed to biochemical researches.
The ozonized solution causes a peak latence decrease of a negative phase in caused potentials to 85 %, from an initial level, in combination with a convertible short-term (10 min) augmentation of the positive phase amplitude in caused potential (26 %). Simultaneously, insignificant raises of the initial peroxidation lipid products were obtained in the researched site of the brain.
The enzymes activity of the respiratory chain does not change simultaneously with the appreciable intensifying of oxidoreductases, activity such as: lactat- dehydrogenases, piruvatdehydrogenases, succinatedehydrogenases.
The ozonized solution stimulates the aerobic glycolysis, raises functional neurones activity of the top cortical layers, not rendering any toxic effect on the excitability and conduction of the nervous tissue

Ozone Research Center.
The reaction of ozone with lipids occurs exclusively at the level of carbon-carbon double bonds present in the polyunsaturated fatty acids, organic peroxides and generating ozonides, which in adequate amounts and controlled exert different biological actions, which give a set ozone therapeutic properties.
In this work we studied the possible mutagenic effects of ozone applied rectally. We used analysis of bone marrow in NMRI mice by the micronucleus test and SPRD rats using the chromosome aberration test. Two concentrations were used ozone (50 and 75 mg / mL). As negative and positive controls were used oxygen and cyclophosphamide (40 mg / kg) respectively. 10 administrations were performed every 24 hours. At the end of treatment animals were sacrificed and processed for bone marrow preparations.
The results show no evidence of cytotoxic or clastogenic (induction of chromosome aberrations) in the bone marrow of rodents treated.

Protective Effects of O3 Ozone Oxidative Preconditioning Against Liver Ischemia/Reperfusion Injury in Rats.
León O.S. and Ajamiech H.
Liver transplantation is a recommended therapy for end-stage liver disease and the demand for donor organs has surpassed the supply resulting in the death of thousands of patients. The damage by hepatic ischemia/reperfusion (I/R) is considered as the main responsible of organic failure after transplantation. On the other hand, 30% of transplants still fail by acute or chronic rejection within five years.
The mechanisms of acute liver damage following I/R are thought to involve a complex interaction of immediate cellular damage caused by different mediators.
In the process of prolonged ischemia, a major caused of primary liver dysfunction in donor grafts results from the generation of reactive oxygen species (ROS) which are associated to pathogenesis of inflammatory disorders including I/R injury.
From the mechanism of Ozone Oxidative Preconditioning (OzoneOP) invoked by our research group, it is shown the protective effects of ozone on important enzymes as Xanthine Deshidrogenase-Xanthine Oxidase and Superoxide Dismutase: CuZn/SOD and Mn/SOD, among others).
It is demonstrated that Ozone OP regulate the Nitric Oxide levels and other mediators which take part in the cellular redox balance.
Ozone OP participation in the novo protein synthesis as protector mechanism for morphological integrity of the liver in the preconditionated groups is shown.
The protection conferred by ozone treatment indicates that this therapeutic alternative may be successful against hepatic damage mediated by I/R associated to liver transplantation.

Treatment with ozone (O3) has gained prominence because of its efficacy in various diseases associated with deficits in antioxidant defenses. However, this has proven toxic gas inhalation and have been reported studies have demonstrated its mutagenic and genotoxic in microorganisms in animals and human cells in vitro. Colorectal insufflation of the pathways is the most widely used in therapy application and whereby the mucosal cells are directly exposed to the agent.
To study the effect of treatment on colorectal cells as well as the effect on peripheral blood leukocytes was used the rat as an experimental model, which has been used successfully in other trials with O3. Rats were treated for 4 d with 42 mg / mL for body weight. It also used an untreated control (NT) and a positive control with bleomycin (BLM).
Samples were taken after different treatments with the gas. DNA damage occurred both in exfoliated cells and in leukocytes and showed a gradual increase of the length of migration and the percentage of damaged cells as a function of sampling time.
The samples after 48 h of treatment indicate a trend toward recovery of the damage or removal of damaged cells nonviable.
Through this study it is found that O3 damage generated both in cells directly exposed, as in leukocytes. In the latter case is probably due to the action of its reactive intermediates.

At the end of treatment, all rats were implanted them under aseptic conditions, intraperitoneally, two sheets coverslips and then closed cavity. These slides were taken at 24 h (subgroups C1 and E1), at 3 (subgroup C3 and E3) and 4 d (subgroups C4 and E4), each subgroup containing 6 animals. Two hours before removal of the plates were inoculated with 0.5 mL of washed RBCs in saline rooster, which enable the evaluation of the phagocytic activity of mononuclear cell inflammation present in the sheets. The rats were anesthetized with a mixture xilaxin / ketamine, prior to extraction of the sheets. The cells attached to these sheets were fixed and set with reagent-May Grümwald Giensa and mounted on the corresponding slide.
Readings were taken with a light microscope in successive fields to reach 100 mononuclear cells. It also measured tumor necrosis factor (TNF) in subgroups E1, E3, E4 and a control group where only the anesthetic was applied, since it is known that drugs can have some influence on the TNF.
Yielded a significant increase (p <0.005) in phagocytic index in the subgroups E1, E3 and E4 with respect to the subgroups C1, C3 and C4, as well as the number of cells that had phagocytosed. With regard to TNF was not observed increase thereof in either group pretreated with ozone or the group with anesthetic alone.

There are no known methods to predict which organ will work better after having had warm and cold ischemia followed by reperfusion. It was our purpose in this paper to assess the effect of ozone on rat kidneys subjected to warm ischemia, and compare the function of kidneys previously treated with ozone compared to other groups. Another objective was constituted to assess the effect of ozone on direct and indirect indicators of oxidative stress and determine the optimal period of treatment with ozone.
Our work took 80 Wistar rats of 250 g, female, grouped into 8 sets of 10 animals each which caused him renal ischemia for 30 min, followed by 3 h of reperfusion and flow midiéndosele renal plasma and the intensity of glomerular filtration and functional variables and biochemical variables by spectrophotometric techniques deterninó superoxide dismutase (SOD), phospholipase A2 and fructosamine.
Morphological studies were also conducted to determine the structural changes that appeared during the experiment. The working groups were distributed as follows: healthy control group (I), ischemic control group (II), oxygen control group at 5 d (III), oxygen control group at 10 d (IV), control group oxygen at 15 d (V), ozone group at 5 d (VI), ozone group at 10 d (VII), ozone group at 15 d (VIII).
The results showed a marked decrease in renal plasma flow and glomerular filtration rate in all groups (control ischemic, control oxygen of 5, 10 and 15 d of treatment, except for the group previously treated with ozone which values remained statistically similar to healthy controls.
Biochemical variables yielded equivalent results.
Structural lesions were significantly lower in the group treated with ozone at 15 d specifically in relation to ischemic controls and oxygen. interpreting the results is dependent on action to improve the rheological properties of the movement known ozone and the effect of "preconditioning" of the same protecting the body from oxidative stress.
