Abstract
Our hypothesis that controlled ozone applications interfere with the redox balance of a biological organism (first published in 1998 with a preclinical trial on protecting the liver from CCl4 intoxication) has been verified over the past two decades in reactive oxygen species (ROS)-induced mitochondrial pathologies, such as rheumatoid arthritis, osteoarthritis, aging processes and type 2 diabetes, and in the prevention of intoxications. Low-dose ozone acts as a redox bioregulator: the restoration of the disturbed redox balance is comprehensible in a number of preclinical and clinical studies by a remarkable increase in the antioxidant repair markers, here mainly shown as a glutathione increase and a reduction in oxidative stress markers, mainly malondialdehyde. The mechanism of action is shown, and relevant data are displayed, evaluated and comprehensively discussed: the repair side of the equilibrium increases by 21% up to 140% compared to the non-ozone-treated groups and depending on the indication, the stress markers are simultaneously reduced, and the redox system regains its balance.

Abstract
The best form of prevention against human infection through bacteria, viruses, and other parasites is ozone disinfection of wastewater and drinking water as a highly effective, well-known method. Various preclinical studies showed promising results, which are being revisited and reconsidered in times of pandemics and led to interesting results in recent clinical trials and reports, as presented by the example of protective measures against COVID-19 in particularly vulnerable clinical personnel. The application of ozone in the form of the low-dose concept induces its regulation by interference of ozone or its peroxides into the redox equilibrium of the biological system, which finally results in the restoration of the glutathione equilibrium. The antioxidant system is activated, the immune system is modulated, and thus the defense mechanisms are improved. In patients with rheumatoid arthritis, repeated ozone treatments have led to new findings in "immunomodulation" through ozone. The more effective immune response is discussed as the response of innate immune memory and opens interesting aspects for complementary treatment of autoimmune diseases.

Cytoprotective remedies for ameliorating nephrotoxicity induced by renal oxidative stress. Life Sci 2023; 318:121466. [PMID: 36773693 DOI: 10.1016/j.lfs.2023.121466] [Citation(s) in RCA: 6] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 01/27/2023] [Accepted: 01/27/2023] [Indexed: 02/11/2023]
Abstract
AIMS Nephrotoxicity is the hallmark of anti-neoplastic drug metabolism that causes oxidative stress. External chemical agents and prescription drugs release copious amounts of free radicals originating from molecular oxidation and unless sustainably scavenged, they stimulate membrane lipid peroxidation and disruption of the host antioxidant mechanisms. This review aims to provide a comprehensive collection of potential cytoprotective remedies in surmounting the most difficult aspect of cancer therapy as well as preventing renal oxidative stress by other means. MATERIALS AND METHODS Over 400 published research and review articles spanning several decades were scrutinised to obtain the relevant data which is presented in 3 categories; sources, mechanisms, and mitigation of renal oxidative stress. KEY-FINDINGS Drug and chemical-induced nephrotoxicity commonly manifests as chronic or acute kidney disease, nephritis, nephrotic syndrome, and nephrosis. Renal replacement therapy requirements and mortalities from end-stage renal disease are set to rapidly increase in the next decade for which 43 different cytoprotective compounds which have the capability to suppress experimental nephrotoxicity are described. SIGNIFICANCE The renal system performs essential homeostatic functions that play a significant role in eliminating toxicants, and its accumulation and recurrence in nephric tissues results in tubular degeneration and subsequent renal impairment. Global statistics of the latest chronic kidney disease prevalence is 13.4 % while the end-stage kidney disease requiring renal replacement therapy is 4-7 million per annum. The remedial compounds discussed herein had proven efficacy against nephrotoxicity manifested consequent to impaired antioxidant mechanisms in preclinical models produced by renal oxidative stress activators.

Abstract
Ozone (O3) is a reactive oxygen species (ROS) that can interact with cellular components and cause oxidative stress. Following said logic, if O3 induces such a stressful milieu, how does it exert antioxidant functions? This is mediated by controlled toxicity produced by low concentrations of O3, which enhance the cell’s suppliance of antioxidant properties without causing any further damage. Therapeutic concentrations vary extensively, although 50 µg/mL is commonly used in experimental and clinical procedures, given that augmented concentrations might work as germicides or cause endogenous damage. O3 therapy has been shown to be effective when applied before or after traumatic renal procedures, whether caused by ischemia, xenobiotics, chronic damage, or other models. In this review, we focus on discussing the role of O3 therapy in different models of kidney damage associated with fibrosis, apoptosis, oxidative stress, and inflammation. We integrate and report knowledge about O3 in renal therapy, debunking skepticism towards unconventional medicine, explaining its proven therapeutic properties, and thus providing background for its use in further research as well as in clinical settings.

Abstract
Objectives Sleep deprivation is a common health problem in modern society and is negatively associated with deleterious effects on cognitive functions such as learning and memory ability. This study was undertaken to provide a detailed account of the effect of chronic ozone intraperitoneal injection on the deleterious effects of sleep deprivation on brain function in rats. Materials and Methods Sleep deprivation was induced using the modified multiple platform model. The rats received REM sleep deprivation with an intraperitoneal injection of ozone or midazolam for 28 days. The effects of ozone on REM sleep deprivation-induced hippocampus-dependent learning and memory deficits were studied by the following approaches: Morris water maze (MWM) tests were used to evaluate spatial learning and memory of rats. Morphological changes in the brain were evaluated using hematoxylin and eosin (HE) staining. RNA-sequence was performed to seek a common mechanism. The expression of the targeted gene was examined by qPCR and Western blotting. Results Ozone intraperitoneal injection reversed spatial learning and memory deficits associated with REM sleep deprivation, ameliorating pathological brain damage and down-regulating the hippocampal expression of Sema3A in rats after REM sleep deprivation. Conclusion Ozone intraperitoneal injection alleviated sleep deprivation-induced spatial learning and memory deficits by protecting hippocampal neurons via down-regulation of the expression of Sema3A in the hippocampus.

Abstract
Systems medicine is founded on a mechanism-based approach and identifies in this way specific therapeutic targets. This approach has been applied for the transcription factor nuclear factor (erythroid-derived 2)-like 2 (Nrf2). Nrf2 plays a central role in different pathologies including neurodegenerative disorders (NDs), which are characterized by common pathogenetic features. We here present wide scientific background indicating how a natural bioactive molecule with antioxidant/anti-apoptotic and pro-autophagy properties such as the ozone (O3) can represent a potential new strategy to delay neurodegeneration. Our hypothesis is based on different evidence demonstrating the interaction between O3 and Nrf2 system. Through a meta-analytic approach, we found a significant modulation of O3 on endogenous antioxidant-Nrf2 (p < 0.00001, Odd Ratio (OR) = 1.71 95%CI:1.17-2.25) and vitagene-Nrf2 systems (p < 0.00001, OR = 1.80 95%CI:1.05-2.55). O3 activates also immune, anti-inflammatory signalling, proteasome, releases growth factors, improves blood circulation, and has antimicrobial activity, with potential effects on gut microbiota. Thus, we provide a consistent rationale to implement future clinical studies to apply the oxygen-ozone (O2-O3) therapy in an early phase of aging decline, when it is still possible to intervene before to potentially develop a more severe neurodegenerative pathology. We suggest that O3 along with other antioxidants (polyphenols, mushrooms) implicated in the same Nrf2-mechanisms, can show neurogenic potential, providing evidence as new preventive strategies in aging and in NDs.

Cell Biosci 2020; 10:120.

Abstract
BACKGROUND Heat shock protein (HSP) 20 is a molecular chaperone that exerts multiple protective functions in various kinds of tissues. However, the expression of HSP20 and its specific functions in airway epithelial cells (AECs) remain elusive. RESULTS In current study, we first confirmed the inducible expression of HSP20 in mouse AECs and in a human bronchial epithelial cell line BEAS-2B cells, under different oxidant stressors. Then by establishing a HSP20-abundant mouse model with repeated low-level-ozone exposures and stimulating this model with a single high-level ozone exposure, we found that the HSP20 abundance along with its enhanced phosphorylation potentially contributed to the alleviation of oxidative injuries, evidenced by the decreases in the bodyweight reduction, the BAL neutrophil accumulation, the AECs shedding, and the BAL concentrations of albumin and E-cadherin. The biological function of HSP20 and its molecular mechanisms were further investigated in BEAS-2B cells that were transfected with HSP20-, unphosphorylatable HSP20(Ala) or empty vector plasmids prior to the stimulation of H2O2, of which its oxidant capacity has been proved to be similar with those of ozone in an air-liquid culture system. We found that the H2O2-induced intracellular ROS level and the early cell apoptosis were attenuated in the HSP20- but not HSP20(Ala)- transfected cells. The intracellular expression of NQO-1 (mRNA and protein) and the intranuclear content of Nrf2 were significantly increased in the HSP20- transfected cells but not in the HSP20(Ala)- and empty vector-transfected cells after the stimulation of H2O2. CONCLUSIONS The inducible expression of HSP20 in AECs by oxidative stress exerts protective roles against oxidative damages, which may involve the activation of the Nrf2-NQO-1 pathway.

Abstract
(1) Background: Cancer is one of the leading causes of mortality worldwide. Radiotherapy and chemotherapy attempt to kill tumor cells by different mechanisms mediated by an intracellular increase of free radicals. However, free radicals can also increase in healthy cells and lead to oxidative stress, resulting in further damage to healthy tissues. Approaches to prevent or treat many of these side effects are limited. Ozone therapy can induce a controlled oxidative stress able to stimulate an adaptive antioxidant response in healthy tissue. This review describes the studies using ozone therapy to prevent and/or treat chemotherapy-induced toxicity, and how its effect is linked to a modification of free radicals and antioxidants. (2) Methods: This review encompasses a total of 13 peer-reviewed original articles (most of them with assessment of oxidative stress parameters) and some related works. It is mainly focused on four drugs: Cisplatin, Methotrexate, Doxorubicin, and Bleomycin. (3) Results: In experimental models and the few existing clinical studies, modulation of free radicals and antioxidants by ozone therapy was associated with decreased chemotherapy-induced toxicity. (4) Conclusions: The potential role of ozone therapy in the management of chemotherapy-induced toxicity merits further research. Randomized controlled trials are ongoing.

Abstract
Aging is a normal process associated with neurodegenerative changes resulting in decline of cognitive and motor functions. Oxidative stress plays an important role. Controlled ozone (O3) therapy has been proved to induce oxidative preconditioning thus reversing oxidative stress. To the best of our knowledge, this research is the first attempt to investigate whether the antioxidant properties of O3 can ameliorate age-associated structural alterations of the cerebral cortex. Ozone administration (at a dose of 0.7mg/kg intraperitonially, three times a week for eight weeks) produced significant downregulation of tissue malondialdehyde (MDA) and upregulation of glutathione, superoxide dismutase (SOD) and catalase (CAT) within the frontal cortex of aged rats. Sections of the frontal cortex from adult and aged rats were stained with hematoxylin and eosin and analyzed using light microscopy. In addition, quantitative immunohistochemical assessments of the expression of inducible nitric oxide synthase (iNOS), caspase-3, glial fibrillary acidic protein (GFAP), Ki67 and acetylcholinesterase (AChE) were performed. Our results revealed the beneficial effect of O3 in improving the neurodegenerative changes of the cerebral cortex of aged rats. Moreover, this study clarified that O3 exerted its effects via reducing oxidative stress, apoptosis, gliosis as well as improving neurogenesis and cholinergic plasticity. This work added to the previously proved aging - associated neurodegenerative effects and provided a new insight into the promising role of O3 to ameliorate these effects.

Abstract
The aim of study was to determine the effects of ozone therapy on the oxidative stress, cardiac functions and clinical findings in patients with heart failure reduced ejection fraction (HFrEF). A total of 40 patients with New York Heart Association 2 and 3 HF with left ventricular ejection fraction (LVEF) <35%, and 40 subjects without HF as control group were included in the study. Patients with HFrEF were given additional ozone therapy of major and minor administrations along with conventional HF treatment for 5 weeks. Before and after ozone therapy, left ventricular end-systolic and end-diastolic volumes (LVESV, LVEDV) and the 6 minute walk distance (6MWD) and blood levels of the superoxide dismutase (SOD), catalase (CAT), glutathione (GSH), glutathione peroxidase (GSHPx), malondialdehyde (MDA), nitric oxide (NO) and N-terminal pro-brain natriuretic peptide (NT-proBNP) were measured. Ozone therapy significantly reduced the serum levels of NO and MDA (p < 0.001, respectively) and significantly increased the levels of SOD, CAT, GSH and GSHPx (p < 0.001, respectively). LVEDV and LVESV were found to be significantly reduced; however, LVEF was not found to be significantly increased (p = 0.567). As the biochemical improvement marker of HF, NT-proBNP was significantly reduced (p < 0.001). The clinical HF improvement marker of 6 minute walk distance was also modestly increased (p < 0.001). Ozone therapy might be beneficial in terms of activating antioxidant system and merit further therapeutic potential to conventional HF treatment in patients with HFrEF.

Abstract
Tumor hypoxia is a severe problem affecting tumor therapy because it reduces the sensitivity of chemotherapy and radiation therapy. Ozone has been known to improve peripheral blood perfusion and oxygen partial pressure. The effect of ozonated water on tumor hypoxia, alone and in combination with an antitumor drug was studied in the present study. Following intraperitoneal administration of ozonated water to colon-26-bearing mice, the Hoechst 33342-positive area and the intratumoral oxygen partial pressure was significantly increased. The tumor growth rate was more suppressed when ozonated water was combined with cisplatin (CDDP) compared with CDDP treatment alone. The number of Ki-67-positive cells significantly decreased, whereas the number of TUNEL-positive cells significantly increased. The present study showed that ozonated water increased intratumoral blood perfusion and improved tumor hypoxia. In addition, ozonated water increased the therapeutic effect of CDDP. These findings, as well as previous reports, suggest that tumor growth is suppressed after treatment with ozonated water as the amount of CDDP reaching the tumor is increased when the intratumoral blood perfusion is increased due to the ozonated water. Thus, the administration of ozonated water may be a new therapeutic approach to solve current concerns regarding antitumor treatment.

Abstract
OBJECTIVES This study aims to determine the effects of ozone therapy on restoring impaired Nrf2 activation to ameliorate chronic tubulointerstitial injury in rats with adenine-induced CKD. MATERIALS AND METHODS Sprague-Dawley rats were fed with 0.75% adenine-containing diet to induce CKD and chronic tubulointerstitial injury. Ozone therapy was administered by rectal insufflation. After 4 weeks, serum and kidney samples were collected and analyzed. Renal function and systemic electrolyte level were detected. Pathological changes in kidney were assessed by hematoxylin-eosin staining and Masson trichrome staining. Nrf2 activation was detected by immunohistochemistry and Western blot analyses. The levels of SOD, CAT, GSH, PCO, and MDA were detected in the kidney. Immunohistochemistry, Western blot, and real-time PCR analyses were performed to evaluate the activation of the nuclear factor kappa B (NF-κB) P65 pathway and inflammation infiltration in the tubulointerstitium of the rats. RESULTS Ozone therapy improved severe renal insufficiency and tubulointerstitial morphology injury as well as restored Nrf2 activation and inhibited the NF-κB pathway in rats with adenine-induced CKD. Ozone therapy also up-regulated anti-oxidation enzymes (SOD, CAT, and GSH) and down-regulated oxidation products (PCO and MDA), as well as inflammatory cytokines (IL-1β, IL-6, TNF-α, and ICAM-1) in the kidney. CONCLUSION These findings indicated that ozone therapy could attenuate tubulointerstitial injury in rats with adenine-induced CKD by mediating Nrf2 and NF-κB.

Abstract
Cisplatin is frequently being used for the treatment of different tumors, although the application of this agent is associated with nephrotoxicity. Here, we explored the antioxidant and anti-inflammatory activities of Physalis alkekengi and Alhagi maurorum; 400 mg kg(-1) per day P. alkekengi and 100 mg kg(-1) per day A. maurorum were administered in rats, orally for 10 days after a single dose of 7 mg kg(-1) intraperitoneal cisplatin. The concentrations of creatinine, urea-nitrogen, and relative and absolute excretion of sodium/potassium were evaluated before/after therapy. Levels of malondialdehyde (MDA) and ferric-reducing antioxidant power (FRAP) were measured to assess the oxidative stress induced by cisplatin. Moreover, tissues sections were used for histological analyses and evaluation of the degree of tissue damage. Cisplatin increased serum levels of creatinine and urea-nitrogen, relative/absolute excretion of sodium/potassium, and MDA, whereas decreased FRAP level. Interestingly, P. alkekengi or A. maurorum were able to reduce the level of the renal function markers as well as the levels of sodium/potassium. This effect was more pronounced by P. alkekengi. Moreover, cisplatin induced pathological damage in kidney, whereas treatment with these agents improved this condition. Our findings demonstrate the potential therapeutic impact of P. alkekengi and A. maurorum for improving cisplatin-induced nephrotoxicity, supporting further investigations on the novel potential clinical application of these agents for patients being treated with cisplatin to ameliorate cisplatin-induced nephrotoxicity.

Abstract
Cisplatin (CP) is a widely used anticancer drug; however, it has several side effects such as nephrotoxicity. Ginger, the rhizome of Zingiber officinale, consumed since ancient times has numerous health benefits. The objective of this work was to evaluate the protective effect of ginger extract (GE) against CP-induced nephrotoxicity. CP group displayed a marked renal failure characterized by a significant increase in serum creatinine and blood urea nitrogen (BUN) levels in addition to severe histopathological and ultrastructural renal alterations. Also, CP group showed an increase in the immunohistochemical expression of Bax proapoptotic protein. In contrast, GE+CP group showed significant decrease in the elevated serum creatinine and BUN levels and an improvement in the histopathological and ultrastructural renal injury induced by CP. The overexpression of Bax proapoptotic protein was significantly decreased in the GE+CP group. Hence, the present results indicated that GE has a protective effect against CP-induced renal damage in rats. Thereby, such findings recommended the usage of GE to prevent and/or decrease the renal damage induced by CP chemotherapeutic treatment.

Abstract
PURPOSE Clinical use of cisplatin is limited by its nephrotoxicity. Cisplatin-induced nephrotoxicity is associated with an increase in oxidative stress, leading ultimately to kidney dysfunction. The aim of this study was to investigate the effect of pomegranate seed oil against nephrotoxicity induced by cisplatin in adult rats. METHODS Animals were divided into four groups. Group I received corn oil (1 mL/kg). Group II received cisplatin (8 mg/kg). Group III and IV received pomegranate seed oil (PSO) 0.4 mL/kg and 0.8 mL/kg one hour before cisplatin injection for 3 days, respectively. Blood samples were collected by cardiac puncture and used for measuring urea and creatinine concentration. Twenty-hour urine samples were collected to measure protein and glucose concentration. The right kidney fixed in formalin for histological examination and the left kidney was homogenized for measurement of malondialdehyde and total sulfhydryl groups. RESULTS A significant elevation of serum creatinine, urea, urinary glucose, protein concentrations, and non-significant decrease in total thiol content and increase in MDA level in kidney homogenates were observed in cisplatin-treated rats. Also cisplatin reduced animal's body weight. Mild-to-moderate tubular cell necrosis, hyaline casts, and vascular congestion were observed in group II. PSO pre-treatment significantly decreased urinary protein, glucose, and serum creatinine concentration. PSO also caused a decrease in serum urea, renal MDA, and increase in thiol content, but the level of these parameters were not significant. CONCLUSION The present results suggest that PSO is an effective agent for the prevention of cisplatin-induced renal dysfunction and oxidative damage in rat.

Abstract
The ageing process is known to be accompanied by increased oxidative stress and compromised antioxidant defenses. Controlled ozone administration has been shown to be effective in various pathophysiological conditions with an underlying oxidative burden. However, its effect on the biochemical alterations associated with the ageing process has been rarely studied. Therefore, the present work was carried out to study the role of ozone in counteracting the state of oxidative stress associated with ageing in rat liver and kidneys using two experimental models. In the pre-ageing model, ozone was administered prior to the onset of ageing at adulthood and continued after the start of the ageing process (3-month-old rats until the age of 15 months). While in the post-ageing model, ozone was administered after ageing has begun and lasted for one month (14-month-old rats until the age of 15 months). The pre-ageing ozone administration effectively reduced lipid and protein oxidation markers, namely, malondialdehyde and protein carbonyl levels and decreased lipofuscin pigment deposition in rat liver and kidneys. Moreover, it significantly restored hepatic and renal reduced glutathione (GSH) contents and normalized cytosolic hepatic glutathione peroxidase activity. Similar but less pronounced effects were observed in the post-ageing ozone-treated group. Nevertheless, in the latter model ozone administration failed to significantly affect liver and kidney lipofuscin levels, as well as kidney GSH contents. These data provide evidences for potentially positive effects of pre-ageing ozone therapy in neutralizing chronic oxidative stress associated with ageing in rat liver and kidneys.

Abstract
OBJECTIVES The goal of the study was to look at the potential protective effect of ozone therapy by studying its antioxidant and vasodilatation effects against hearing loss caused by acoustic trauma. METHODS Thirty-two male Wistar Albino rats were divided into four groups of eight. The 1st group was exposed to acoustic trauma, the 2nd group was treated with ozone initially, and was exposed to acoustic trauma 24 h later, the 3rd group received ozone without trauma, while the 4th group was the control group. The 1st and 2nd groups were exposed to acoustic trauma with 105 dB SPL white band noise for 4h. DPOAE and ABR tests were conducted in all groups on the 1st, 5th, and 10th days after trauma. RESULTS In the 1st group, the effects of acoustic trauma continued on days 1, 5 and 10. The 2nd group's DPOAE and ABR results on days 5 and 10 showed significant improvement at all frequencies compared to deterioration on day 1, and the readings were comparable to baseline measurements. CONCLUSION Acoustic trauma is a pathology that is experienced frequently and leads to many problems in terms of health and cost. Ozone was demonstrated to be a reparative substance against acoustic trauma and, in addition, it can be supplied and applied easily.

Abstract
BACKGROUND Headache afflicts approximately 10%-15% of the general population. Mixed results are obtained from various therapies, usually drugs, but also oxygen inhalation, behavioral psychology, physical therapy, and peripheral or central neurostimulation. When refractory to treatment, it has severe impact on quality of life. OBJECTIVES/SUBJECTS: Five (5) patients are presented who had suffered from severe/persistent headache refractory to standard management (including 5-HT1 agonist triptan drugs) and were treated with ozone therapy. INTERVENTIONS Ozone administration was by major autohemotherapy. The procedure involved venous blood drawn into a sterile single-use glass bottle containing anticoagulant, gently mixed with an equal volume of O3/O2 gas mixture (prefiltered through a sterile 0.20-μm filter) and slowly reinfused back into the donor patient via the antecubital vein. OUTCOME MEASURES The analyzed parameters were analgesia requirements, days of sick leave due to headache, number of headache events, and pain intensity according to the visual analogue scale (VAS); these recorded at three time points: pre-ozone therapy, post-ozone therapy, and before the last follow-up (mean: 64.6±36.8 months). RESULTS The number of headache episodes pretreatment (n=80; range 5-200) was significantly decreased during the first 6 months post-treatment (n=0, range 0-1; p=0.042) and over the 6 months before the last follow-up visit (n=1, range 0-2; p=0.043). The corresponding VAS scores were 8.7±0.8 pretreatment versus 1.1±2.5 the 6 months post-treatment (p=0.003) and versus 3.1±3.3 the 6 months before last follow-up visit (p=0.036). CONCLUSIONS Ozone therapy decreased headache episodes and pain severity over a protracted period. This novel approach is effective and merits further research.

Abstract
BACKGROUND Several studies have demonstrated the beneficial effects of ozone oxidative preconditioning in several pathologies characterized by cellular oxidative and inflammatory burden. The present study was designed to investigate the cardioprotective effects of oxidative preconditioning in ischemia/reperfusion (I/R) injury. METHODS Rats were randomly assigned into five groups. Groups 1 and 2 were normal and I/R groups, respectively. Two of the other groups received two different doses of ozone therapies by rectal insufflations. The last group received vehicle (oxygen). Rats were subjected to myocardial I/R (40 min/10 min). Heart rate and ventricular arrhythmias were recorded during I/R progress. At the end of reperfusion, plasma creatine kinase-MB (CK-MB) activity and total nitrate/nitrite (NO(x)) were determined. In addition, lactate, adenine nucleotides, thiobarbituric acid reactive substances (TBARS), reduced glutathione (GSH) and myeloperoxidase (MPO) activity were estimated in the heart left ventricle. Histological examination was also performed to visualize the protective cellular effects. RESULTS Both doses of ozone therapy were equally protective in reducing CK-MB release. However, the higher dose was more effective in reducing oxidative stress, lactate accumulation, elevated MPO activity and plasma NO(x) as well as preserving myocardial adenine nucleotides. Histological examination also revealed better improvement with a higher dose of ozone therapy compared to the I/R group. CONCLUSION Ozone therapy can afford significant cardioprotection against biochemical and histological changes associated with I/R injury.

Abstract
Acetaminophen (APAP), also known as paracetamol, is the commonest cause of toxic ingestion in the world. Because overdose of APAP has life-threatening effects on kidney, treatment of APAP-induced nephrotoxicity has life-saving importance. Aim of the study was to evaluate the efficacy of medical ozone therapy in experimental model of APAP toxication. Twenty-one male Wistar rats (200-250 g) were randomly assigned into three groups containing seven rats each: Sham, control (only APAP treated), and APAP + ozone therapy groups. Rats were killed 48 hours after administration of APAP. Urea, creatinine levels in the blood, and malondialdehyde (MDA), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) activity in renal tissue were measured. Kidney tissues were stained with hematoxylin and eosin for histological assessment. APAP administration deteriorated the renal functions and significantly elevated renal MDA levels and depleted SOD and GSH-Px activities. Ozone therapy significantly reduced the MDA level, increased the SOD and GSH-Px activities, and normalized the renal histology. In conclusion, our study results are consistent with encouraging data for ozone therapy on APAP-induced nephrotoxicity in rats by improving antioxidant mechanism and oxidative stress.

Abstract
The present study investigated the modulatory role of phenolic extract of soybean (PESB) in a rat model of nephrotoxic acute renal failure induced by cisplatin. Cisplatin (2 mg/kg/day) was administered to the rats for 5 days and the animals were pretreated with PESB (250-1000 mg/kg). Blood urea nitrogen reduced by 49.8% and 59.0%, serum creatinine by 34.7% and 62.1% and urinary N-acetyl-beta-D-glucosaminidase also decreased by 37.7% and 49.2% following treatment with 250- and 500-mg/kg doses of the extract respectively in the cisplatin-treated rats. The extract also significantly increased renal myeloperoxidase activity by 26.8% and 40.6% at these doses. PESB also decreased renal xanthine oxidase activity and serum nitrate/nitrite in the cisplatin-treated rats. In addition, PESB significantly attenuated the marked renal oxidative damage that accompanied cisplatin treatment. The extract improved liver histology and significantly increased the activities of the antioxidant enzymes measured [superoxide dismutase, catalase, glutathione-S-transferase], prevented glutathione depletion and decreased malondialdehyde level following cisplatin treatment. Furthermore, cisplatin-induced decrease in the activities of glucose-6-phosphatase and 5'-nucleotidase in these rats was attenuated only at 250 mg/kg dose of the extract. We concluded therefore that PESB via antioxidant and possibly anti-inflammatory actions offered protective benefit against cisplatin-mediated acute toxic injury to the kidney.

Abstract
The medical use of low level laser (LLL) irradiation has been occurring for decades, primarily in the area of tissue healing and inflammatory conditions. Despite little mechanistic knowledge, the concept of a non-invasive, non-thermal intervention that has the potential to modulate regenerative processes is worthy of attention when searching for novel methods of augmenting stem cell-based therapies. Here we discuss the use of LLL irradiation as a "photoceutical" for enhancing production of stem cell growth/chemoattractant factors, stimulation of angiogenesis, and directly augmenting proliferation of stem cells. The combination of LLL together with allogeneic and autologous stem cells, as well as post-mobilization directing of stem cells will be discussed.

Abstract
Cisplatin mediated nephrotoxicity is remarkably documented by reactive oxygen species. Carnosine is a naturally occurring dipeptide and has a scavenging property. The aim of present study was to assess the lipid peroxidation and antioxidant enzymes in association with oxidative stress in cisplatin -treated and 10 subsequent doses of carnosine-pretreated rats. 24 male Albino Wistar rats, were randomly divided into four groups (n=6). Group I remains untreated; Group II received Cisplatin (3 mg / kg) for 5 alternate days; Group III received Carnosine (10 mg / kg) for consecutive 10 days; Group IV received Carnosine (10 mg / kg) before administration of Cisplatin (3 mg / kg). The effects of carnosine on cisplatin-induced nephrotoxicity were evaluated by plasma creatinine, urea, malondialdehyde, nitrate; kidney tissue malondialdehyde, 4-HNE, superoxide dismutase and catalase activities. Cisplatin-induced oxidative stress was indicated by increased level of tissue MDA, 4-HNE and decreased level of tissue GSH, SOD and Catalase. Marked elevation of kidney weight and reduced body weight and pathological changes in kidney tissues were also observed in Cisplatin-treated rats. Carnosine reduced these pathological changes and counteracted the deleterious effects of cisplatin. The results divulge the beneficial effect of Carnosine pretreatment with cisplatin in experimental rat model.

Abstract
Abstract
Objectives
The ischaemia–reperfusion process is largely mediated by reactive oxygen species. Taking into account that a transient and controlled administration of ozone is able to upregulate cellular antioxidant enzymes, a morphological, biochemical and functional renal study was performed in rats undergoing warm renal ischaemia.
Methods
Rats were divided into four groups. All except the negative controls underwent 60 min' bilateral renal ischaemia followed by 10 days' reperfusion. The positive control group received no further treatment. The ozone group received an ozone/oxygen mixture (ozone dose 0.5 mg/kg) immediately after the ischaemia and daily for the 10 days' reperfusion; the oxygen group were given the same concentration of oxygen alone (13 mg/kg). Biochemical parameters fructosamine, phospholipase A2, catalase, superoxide dismutase and thiobarbituric acid reactive substances were measured, as well as renal plasma flow and glomerular filtration rate.
Key findings
Renal plasma flow and glomerular filtration rate decreased significantly in the positive controls and the oxygen group whereas values in the ozone group were similar to those in the negative control group. With respect to the biochemical parameters, ozone maintained a homeostasis redox, with significant increases in catalase and superoxide dismutase activities and similar values for phospholipase A2 and fructosamine compared with the negative control group. Fewer morphological alterations were seen in kidneys from the ozone group. No advantages were obtained in the positive control and oxygen groups.
Conclusions
The protective effect of ozone may be explained by upregulation of the antioxidant defence system and beneficial effects on blood circulation and in oxygen metabolism. Ozone treatment may represent a therapeutic approach for minimising renal damage after transplantation.

Abstract
The reader may be eager to examine in which diseases ozonetherapy can be proficiently used and she/he will be amazed by the versatility of this complementary approach (Table 9 1). The fact that the medical applications are numerous exposes the ozonetherapist to medical derision because superficial observers or sarcastic sceptics consider ozonetherapy as the modern panacea. This seems so because ozone, like oxygen, is a molecule able to act simultaneously on several blood components with different functions but, as we shall discuss, ozonetherapy is not a panacea. The ozone messengers ROS and LOPs can act either locally or systemically in practically all cells of an organism. In contrast to the dogma that “ozone is always toxic”, three decades of clinical experience, although mostly acquired in private clinics in millions of patients, have shown that ozone can act as a disinfectant, an oxygen donor, an immunomodulator, a paradoxical inducer of antioxidant enzymes, a metabolic enhancer, an inducer of endothelial nitric oxide synthase and possibly an activator of stem cells with consequent neovascularization and tissue reconstruction.

Abstract
Even if the reader has only browsed through the previous chapters, he ought to have received my feeling that ozone has an enormous therapeutic potential that, so far, has been either disregarded, if not obstructed by world medical authorities. Reasons for delaying the use of ozone are multiple: while quacks and inexpert ozonetherapists are at fault for poor work, other aspects such as commercial and pharmaceutical interests, prejudice, lack of knowledge and a myopic medical vision have done their best to block a substantial and rapid progress.

Abstract
BACKGROUND The aim of this study was to investigate the protective effects of hyperoxygenated solution (HOS) preconditioning on intestinal ischemia-reperfusion (IR) injury in rabbits. MATERIALS AND METHODS Thirty-two rabbits were randomly divided into four groups as follows: (1) control group in which sham operation was performed (Sham group); (2) sham operation and HOS treatment group (sham+H group); (3) ischemia-reperfusion group (IR group); (4) ischemia-reperfusion and HOS treatment group (H group). Intestinal IR model was produced by clamping superior mesenteric artery with an atraumatic vascular clamp for 1 h, followed by reperfusion for 2 h. Animals in H group received intravenous HOS infusion (20 mL/kg) every day for 5 days before ischemia-reperfusion; animals in the sham+H group received the same amount of HOS before sham operation, and animals in IR group received the same amount of normal saline in the same way. At the end of reperfusion, histopathological changes of intestine were observed, and malondialdehyde (MDA) levels, superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GSH-Px) activities in intestinal tissues were also detected. Intestinal barrier function was assessed by blood d-lactate levels and bacterial translocation (BT). RESULTS The H group showed significantly lower MDA levels and higher activities of SOD, CAT, and GSH-Px in the intestinal tissue compared with the IR group. Furthermore, the mean d-lactate levels and incidence of BT in the H group were significantly lower than those in the IR group. Histopathological analysis also indicated that there were significant histological improvements in the H group compared with the IR group. CONCLUSIONS HOS preconditioning at an appropriate dose ameliorates the deleterious changes in intestinal mucosal injury and barrier function associated with IR by effectively preventing a decrease in the intestinal antioxidant defense system, which is another simple and effective measure to protect intestine from IR injury.

Abstract
BACKGROUND Cellular events in cisplatin-mediated nephrotoxicity include apoptosis induction, decreased protein synthesis, changes in the subcellular redistribution of Bax mitochondrial dysfunction, DNA injury, increased lipid peroxidation, depletion of glutathione and decrease in enzymatic activity of renal antioxidant enzymes. In previous papers we have shown that intra-rectal (i.r.) ozone/oxygen mixture protected and induced a significant recovery in cisplatin-induced renal damage and was related to a significant increase in the antioxidant system in renal tissue. METHODS This study was undertaken to examine the effect of the ir applications of ozone/oxygen mixture in the renal expression pattern of Bax proteins in rats treated with cisplatin. A group of male Sprague-Dawley rats was pretreated with 15 i.r. applications of ozone/oxygen (1.1 mg/kg) before intraperitoneal injection of cisplatin (6 mg/kg). Another group was treated with five i.r. applications of ozone/oxygen mixture after cisplatin administration. Serum creatinine was measured thereafter. Subcellular distribution of Bax in renal tissue was analyzed by immunohistochemistry. RESULTS Ozone pretreatment prevented the increase in serum creatinine levels and completely inhibited the acute tubular necrosis induced by cisplatin in renal tissue, diminishing the expression of Bax. Ozone treatment after cisplatin application reduced the increase in serum creatinine levels and the renal necrosis, inducing a lesser decrease of the Bax expression in cisplatin-treated kidneys. CONCLUSIONS Expression of Bax in renal tissue seems to play an important role in the protection and recovery in cisplatin-nephrotoxicity achieved by ozone/oxygen mixture.

Abstract
Cisplatin (CDDP), an anticancer drug, induces remarkable toxicity in the kidneys of animals and humans and it has been well documented that reactive oxygen species and the renal antioxidant system are strongly involved in acute renal damage induced by CDDP. The aim of the present study was to investigate whether or not the renal antioxidant system plays also an important role in chronic renal damage induced by repeated doses of CDDP (1 mg/kg intraperitoneally twice weekly during 10 weeks in rats). In order to elucidate it, serum creatinine and urea levels, renal glutathione and thiobarbituric acid-reactive substances (TBARS) content, as well as renal superoxide dismutase and glutathione peroxidase activities were measured in the kidney homogenates of chronically CDDP-treated rats and additionally histological studies were performed in the rat kidneys. The chronic treatment with CDDP induced a significant increase in creatinine and urea levels in serum, but the other parameters mentioned above were not significantly modified as compared to the values in nontreated rats. Taking into account these results, we conclude that chronic CDDP administration induces also severe nephrotoxicity, in contrast to CDDP acute application, without any significant modification in the activity of relevant antioxidant enzymes such as superoxide dismutase and glutathione peroxidase, renal glutathione and lipid peroxides, by which the role of the antioxidant system in chronic nephrotoxicity induced by CDDP in rats is uncertain.

Abstract
BACKGROUND The aim of this study was to investigate the effects of intraluminal hyperoxygenated solution (HOS) on enterocyte mitochondrial structure and respiratory function after intestinal ischemia-reperfusion (IR) in rabbits. MATERIALS AND METHODS Thirty-two rabbits were divided randomly into four groups: control group in which sham operation was performed (Sham group), ischemia-reperfusion group (IR group), and two HOS treatment groups (H1 group and H2 group). Intestinal IR model was produced by clamping superior mesenteric artery (SMA) with an atraumatic vascular clamp for 1 h, followed by reperfusion for 2 h. Animals in the H1 group and H2 group received intraluminal HOS infusion for 1 h immediately after occlusion of SMA, and the rates of infusion were 10 and 20 mL/kg.h, respectively. After 2 h of reperfusion, enterocyte mitochondria morphological quantitative analysis was made with electron microscopy and biogenetics stereology, and the following parameters, including mitochondrial respiratory control ratio (RCR), intestinal O(2) extraction ratio (ER), and mucosal ATP contents, were measured, respectively. RESULTS After IR, the mitochondria was severely swollen with broken cristae, and mean transaction area, diameter, surface density, and volume density of the mitochondria increased significantly. Meanwhile, specific surface and numeral density of the mitochondria decreased significantly. The mitochondrial RCR, intestinal O(2) ER, and mucosal ATP contents were all decreased significantly. There were no differences in all parameters between the IR group and H1 group. In the H2 group, the mitochondria were slightly swollen, and mean transaction area, diameter, surface density, and volume density of the mitochondria were all significantly lower, with the specific surface and numeral density of the mitochondria significantly higher compared with the IR group. The mitochondrial RCR, intestinal O(2) ER and mucosal ATP contents in H2 group were all significantly higher than those in IR group. CONCLUSIONS Intraluminal HOS infusion at 20 mL/kg.h during ischemia ameliorates structural and functional changes of enterocyte mitochondria associated with intestinal IR injury, which is a safe, simple, and effective measure to protect the intestine from IR injury.

Abstract
PURPOSE OF REVIEW Acute renal failure remains a significant cause of morbidity and mortality in adults and children. Despite advances in understanding the pathophysiology of acute renal failure, little progress has been made in its treatment. This review assesses the recent data on current and promising new therapies for acute renal failure. RECENT FINDINGS The first section of the review describes the recent therapies that have been used in humans, all of whom have been adults. The second section evaluates the use of agents given in experimental animal models during or after the onset of acute renal failure. The third section describes the many animal studies using therapies before the onset of experimental renal failure. The final section discusses how the emerging field of stem cell research might be used to treat acute renal failure. SUMMARY Among the recent studies in humans, the most intriguing have been the use of atrial natriuretic peptide in patients with nonoliguric renal failure and isotonic sodium bicarbonate infusions to prevent radiocontrast medium-induced renal failure. Among the agents used in animal studies, those with the greatest potential were hepatocyte growth factor and ethyl pyruvate, because they seem to protect against or accelerate recovery from acute renal failure after the renal insult. Finally, stem cell therapy may someday offer the best option for recovery from acute renal failure.

Abstract
The organosulfur compounds (OSCs), present in garlic, are studied for their protective effect against human cancers. P-glycoprotein (P-gp) and multidrug resistance protein 2 (Mrp2) are two transporters involved in the defense of cells and in the development of multidrug resistance. Whereas OSCs increase glutathione S-transferase activity (GST), Mrp2 plays a role in the transport of glutathione (GSH)-conjugates. In this study, we have investigated the effect of two OSCs, diallyl disulfide (DADS) and S-allyl cysteine (SAC), on P-gp and Mrp2 expression in renal brush-border membranes. By Western blot analysis, our results show that DADS induces Mrp2 expression (by 7-fold), which correlates with the rise of GST activity and GSH levels. Surprisingly, a co-administration of OSC with cisplatin, an anticancer drug, significantly increased Mrp2 gene and protein expression (by 30-fold), suggesting that DADS could potentiate the effects of cisplatin. Interestingly, SAC and cisplatin in co-treatment decreased P-gp protein expression and mdr1b isoform mRNA levels. In addition, modulation of the mdr1b isoform and Mrp2 by cisplatin was completely abolished by a glutathione precursor, N-acetyl cysteine. These results indicate that OSCs present in a garlic-rich diet might alter chemotherapeutic treatments using P-gp or Mrp2 substrates.
