Abstract
BACKGROUND Stroke is a leading cause of death worldwide, with oxidative stress and calcium overload playing significant roles in the pathophysiology of the disease. Ozone, renowned for its potent antioxidant properties, is commonly employed as an adjuvant therapy in clinical settings. Nevertheless, it remains unclear whether ozone therapy on parthanatos in cerebral ischemia-reperfusion injury (CIRI). This study aims to investigate the impact of ozone therapy on reducing parthanatos during CIRI and to elucidate the underlying mechanism. METHODS Hydrogen peroxide (H2O2) was utilized to mimic the generation of reactive oxygen species (ROS) in SH-SY5Y cell reperfusion injury in vitro, and an in vivo ischemic stroke model was established. Ozone saline was introduced for co-culture or intravenously administered to mice. Apoptosis and oxidative stress were assessed using flow cytometry and immunofluorescence. Western blotting was utilized to examine the expression of parthanatos signature proteins. The mechanism by which ozone inhibits parthanatos was elucidated through inhibiting PPARg or Nrf2 activity. RESULTS The findings demonstrated that ozone mitigated H2O2-induced parthanatos by either upregulating nuclear factor erythroid 2-related factor 2 (Nrf2) or activating peroxisome proliferator-activated receptorg (PPARg). Furthermore, through the use of calcium chelators and ROS inhibitors, it was discovered that ROS directly induced parthanatos and facilitated intracellular calcium elevation. Notably, a malignant feedback loop between ROS and calcium was identified, further amplifying the induction of parthanatos. Ozone therapy exhibited its efficacy by increasing PPARg activity or enhancing the Nrf2 translation, thereby inhibiting ROS production induced by H2O2. Concurrently, our study demonstrated that ozone treatment markedly inhibited parthanatos in stroke-afflicted mice. Additionally, ozone therapy demonstrated significant neuroprotective effects on cortical neurons, effectively suppressing parthanatos. CONCLUSIONS These findings contribute valuable insights into the potential of ozone therapy as a therapeutic strategy for reducing parthanatos during CIRI, highlighting its impact on key molecular pathways associated with oxidative stress and calcium regulation.

Abstract
OBJECTIVE Methotrexate (MTX) is widely administered for the treatment of various cancers. However, MTX induces male reproductive toxicity. In the current study, the effect of ozone therapy (OT) on reducing the toxic effects of MTX in the mouse testicles has been investigated. METHODS Twenty-four mice were divided into four groups: control, OT (4 mg/kg ozone), MTX (20 mg/kg), and MTX + OT. Testosterone levels, histological changes, and oxidative stress biomarkers were assessed to evaluate the protective effects of OT. RESULTS The results demonstrated that MTX disrupted germinal epithelium, reduced serum testosterone levels, and enhanced oxidative stress in testicular tissue. However, treatment with OT attenuated these adverse effects. OT effectively restored the levels of antioxidant enzymes, such as catalase (CAT), glutathione (GSH), and superoxide dismutase (SOD). OT reduced lipid peroxidation, as indicated by decreased malondialdehyde (MDA) levels. OT preserved normal spermatogenesis, improved morphometric parameters, and reduced histological changes by MTX. Moreover, OT effectively restored testosterone levels. CONCLUSIONS OT protects against MTX-induced testicular damage by suppressing oxidative stress.

Abstract
Testicular torsion is a urological emergency that involves the twisting of the spermatic cord along its course. Compelling pieces of evidence have implicated oxidative stress-sensitive signaling in pathogenesis of testicular I/R injury. Although, surgical detorsion is the mainstay management; blockade of the pathways involved in the pathogenesis may improve the surgical outcome. Experimental studies using various testicular I/R models have been reported in a bid to explore the mechanisms associated with testicular I/R and evaluate the benefits of potential therapeutic measures; however, most are limited by their shortcomings. Thus, this review was intended to describe the details of the available testicular I/R models as well as their merits and drawbacks, the pathophysiological basis and consequences of testicular I/R, and the pharmacological agents that have being proposed to confer testicular benefits against testicular I/R. This provides an understanding of the pathophysiological events and available models used in studying testicular I/R. In addition, this research provides evidence-based molecules with therapeutic potentials as well as their mechanisms of action in testicular I/R.

Abstract
PURPOSE This study was performed to evaluate the effect of ethanolic extract of Turkish propolis (EEP) on testicular ischemia/reperfusion (I/R) damage in rats in terms of biochemistry and histopathology, for the first time. METHODS A total of 18 male Sprague-Dawley rats were divided into three groups with six rats in each group: control, torsion/detorsion (T/D), and T/D+EEP (100mg/kg). Testicular torsion was performed by 720° rotating the left testicle in a clockwise direction. The duration of ischemia was 4h and orchiectomy was performed after 2h of detorsion. EEP was applied only once 30min before detorsion. Tissue malondialdehyde (MDA), total oxidant status (TOS) and total antioxidant status (TAS) levels were determined using colorimetric methods. Oxidative stress index (OSI) was calculated by proportioning tissue TOS and TAS values to each other. Tissue glutathione (GSH) and glutathione peroxidase (GPx) levels were determined using enzyme-linked immunosorbent assay (ELISA) kits. Johnsen's testicle scoring system was used for histological evaluation. RESULTS In the T/D group, it was determined that statistically significant decreasing in TAS, GSH, GPx levels and Johnsen score, and increasing in TOS, OSI and MDA levels (p<0.05) compared with control group. EEP administration statistically significantly restored this I/R damage (p<0.05). CONCLUSION This is the first study to show that propolis prevent I/R-induced testicular damage through its antioxidant activity. More comprehensive studies are needed to see the underlying mechanisms.

Abstract
The aim of the present study was to evaluate the protective effect of gallic acid (GA) against cisplatin (CDDP)-induced ovarian toxicity, for the first time. The ovarian damage was generated with CDDP (5 mg/kg) intraperitoneally (i.p.) administration in rats. GA (2.5 and 5 mg/kg) were administered i.p. for 3 consecutive days. The study was carried out in 5 main groups containing 6 rats in each group: control, GA (5 mg/kg), CDDP, CDDP + GA (2.5 mg/kg) and CDDP + GA (5 mg/kg). The levels of ovarian malondialdehyde (MDA), total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), catalase (CAT), 8-hydroxy-2'-deoxyguanosine (8-OHdG), caspase-3 and tumor necrosis factor-alpha (TNF-α) were determined. Hematoxylin and eosin staining method was employed for the histopathological examination. In the CDDP group, it is determined that statistically significant decreasing in the levels of TAS and CAT, and increasing in the levels of MDA, TOS, OSI, 8-OHdG, caspase-3 and TNF-α (p < 0.05) compared with control group. GA administrations statistically significantly restored this damage (p < 0.05). Although vascular congestion, edema, hemorrhage, follicular degeneration and leukocyte infiltration were significantly higher in the CDDP group than in the control group, GA administrations statistically significantly restored these damages (p < 0.05). In conclusion, this study showed that GA prevented CDDP-induced ovarian damage with its antioxidant, anti-apoptotic and anti-inflammatory activities. More comprehensive studies are needed to see the underlying mechanisms.

Abstract
This study aimed to investigate the protective effect of ozone therapy on ovarian reserve, number of ovarian follicles, ovarian morphology in a rat ischaemia reperfusion (IR) injury model. Twenty-four, Wistar Hannover rats were included. The rats were divided into three groups as control, detorsion-only, and ozone therapy + detorsion groups. There was a statistically significant difference in the follicular damage and inflammation scores between the study groups (p = .019, p = .002, respectively). The highest AMH decrease was observed in the detorsion-only group (p = .012). The total damage score was higher in the detorsion-only group than the ozone therapy + detorsion group. Preantral, small and large antral follicle numbers were less in the detorsion-only group than the ozone therapy + detorsion group. The highest postoperative day 7 TAS level was in the ozone therapy + detorsion group. TOS levels did not differ significantly between the study groups. The combination of the ozone therapy with ovarian detorsion is more effective in protecting the ovarian reserve than ovarian detorsion-only.Impact StatementWhat is already known on this subject? Adnexal torsion is a common gynecological emergency in reproductive-age women. The recommended management is the detorsion of the adnexal pedicle in patients with fertility desire.What do the results of this study add? The combination of the medical ozone therapy with conventional surgical ovarian detorsion is more effective in the protection of the ovarian reserve compared to surgical ovarian detorsion.What are the implications of these findings for clinical practice and/or further research? This study speculates that medical ozone therapy in addition to conventional surgical ovarian detorsion could preserve ovarian reserve and function if confirmed in further clinical studies.

Abstract
Ischemia reperfusion (IR) injury of skeletal muscles is a serious problem because of its local and systemic complications. Previous studies reported that ozone and erythropoietin could alleviate IR effect on several organs. The current research is established to evaluate the possible protective role of ozone versus erythropoietin following IR injury of the gastrocnemius muscle. Fifty rats were equally divided into five groups: I control, II ischemia reperfusion (IR), III post-reperfusion ozone treated, IV post-reperfusion erythropoietin-treated, and V recovering post-reperfusion without treatment groups. The right femoral arteries of all rats were clamped for three hours to induce ischemia then clamps were released to allow reperfusion for two hours. Rats of group II were scarified immediately after reperfusion period. Rats of group III were injected with ozone just after reperfusion for 14 days. Animals of group IV were injected with erythropoietin just after reperfusion for 14 days. Rats of group V rats were kept for 2 weeks following reperfusion without treatment. Blood samples were obtained to estimate lactate dehydrogenase (LDH) and creatine kinase (CK) enzymes. Gastrocnemius muscle was processed for measurement of tissue malondialdehyde (MDA), as well as examination by light and electron microscopes. iNOS and PCNA immunohistochemistry and statistical analysis were applied. The current results indicated that both ozone and erythropoietin could be used as protective agents reducing the muscular damage induced by IR injury.

Abstract
Stroke is the most frequent cause of disability in developed countries. A common phenomenon of stroke, cerebral ischemia, is threatening many lives worldwide. In addition, ozone treatment was previously reported to exert functions in relieving brain injury. In the current study, the therapeutic effects of ozone on cerebral ischemia are investigated. A rat model of middle cerebral artery occlusion (MCAO) was established. The brain water content was calculated by weighing brain tissues, and the 2, 3, 5-triphenyltetrazolium chloride staining was performed to measure brain infarction volume in rats. A colorimetric assay was conducted to examine expression levels of malondialdehyde, superoxide dismutase, catalase, and glutathione in the rat hippocampus. Reverse transcription quantitative polymerase-chain reaction and Western blot analyses were employed to evaluate expression levels of Beclin1, LC3B, p62, and critical factors implicated in the NF-κB signaling pathway. We found that ozone significantly improved the survival rate of MCAO model rats, reduced the cerebral water content, and decreased the neurological scores of ischemic rats. Ozone markedly reduced cerebral ischemia-induced infarction in ischemic rats. Ozone decreased MDA levels and increased SOD, catalase, and GSH levels in the hippocampus of rats. Ozone significantly inhibited autophagy by decreasing Beclin1 and LC3B expression and increasing p62 expression. The ozone inactivated the NF-κB signaling pathway by decreasing the protein levels of TLR4, p-IKKβ, p-IKBα, and p-p65. We conclude that ozone treatment alleviates the brain injury in ischemic rats by suppressing autophagy and inactivating the NF-κB signaling pathway.

Abstract
OBJECTIVE The therapeutic value of cisplatin (CDDP) as an anticancer drug is limited by its ovo-otoxicity. The effect of natural phenolic acids in the prevention of many diseases related to oxidative stress has been reported. Here, the ability of p-coumaric (pCA) acid, a member of phenolic acids, to protect rat ovary tissue against CDDP-induced oxidative stress was investigated. METHODS The study was carried out in five main groups containing six rats in each group: control, pCA (4 mg/kg), CDDP, CDDP plus pCA (2 mg/kg), and CDDP plus pCA (4 mg/kg). The levels of ovarian malondialdehyde (MDA), total oxidant status (TOS), total antioxidant status (TAS), oxidative stress index (OSI), catalase (CAT), 8-hydroxy-2'-deoxyguanosine (8-OHdG), caspase-3, and tumor necrosis factor-alpha (TNF-α) were determined. Hematoxylin and eosin staining method was employed for the histopathological examination. RESULTS In the CDDP group, it is determined that statistically significant decreasing in the levels of TAS and CAT, and increasing in the levels of MDA, TOS, OSI, 8-OHdG, caspase-3, and TNF-α compared with control group (p < 0.05). pCA administration statistically significantly restored this damage in a dose-dependent manner (p < 0.05). Although vascular congestion, edema, hemorrhage, follicular degeneration, and leukocyte infiltration were significantly higher in the CDDP group than in the control group, pCA administrations statistically significantly restored these damages (p < 0.05). CONCLUSIONS The data presented here indicate that pCA protects ovarian tissues of rats against CDDP-induced oxidative stress, inflammation, and apoptosis. It may be worthy to consider the usefulness of pCA as adjuvant therapy in cancer management.

Abstract
BACKGROUND The aim of this study was to investigate the effects of astaxanthin (ASX) on testicular torsion/detorsion (T/D) damage in rats in terms of oxidative stress and endoplasmic reticulum (ER) stress. METHODS Eighteen male Sprague-Dawley rats were divided into three groups with six rats in each group: control, T/D and T/D + 20 mg/kg ASX. Torsion and detorsion times were applied as 4 h and 2 h, respectively. ASX application was performed 30 minutes before detorsion. At the end of the period, testicular tissues were removed and biochemical and histological analyzes were performed. To evaluate the degree of oxidative stress, tissue malondialdehyde (MDA), total oxidant status (TOS) and total antioxidant status (TAS) were determined using colorimetric methods, while tissue superoxide dismutase (SOD) levels were determined using ELISA kit. To evaluate the degree of ER stress, tissue glucose regulatory protein 78 (GRP78), activating transcription factor 6 (ATF6) and C/EBP homologous protein (CHOP) levels were determined using ELISA kits. Johnsen's testicle scoring system was used for histological evaluation. RESULTS In the T/D group, it is determined that statistically significant decreasing in TAS, SOD levels and Johnsen score, and increasing in TOS, OSI, MDA, GRP78, ATF6 and CHOP levels (p < 0.001) compared with control group. ASX administration statistically significantly restored this T/D-induced damage (p < 0.01). CONCLUSION This is the first study to show that ASX prevent T/D-induced testicular damage through its antioxidant activity. More comprehensive studies are needed to see the underlying mechanisms.

Zhang W, Wu M, Chen P, Zhang J, Ma J, Cheng Y, Li X, Hu J, Li W, Du Y, Ding K, Fan Z. Effect of local ozone treatment on rats with anterior rectal resection and the possible mechanisms. Biomed Eng Online 2021; 20:79. [PMID: 34362379 PMCID: PMC8349064 DOI: 10.1186/s12938-021-00918-z] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/23/2021] [Accepted: 07/28/2021] [Indexed: 11/10/2022] Open
Abstract
BACKGROUND Anterior resection syndrome (ARS) is characterized by the diverse and interchangeable evacuatory symptoms that may occur following distal colorectal resection. We aimed to investigate the effect and potential mechanisms of ozone perfusion on rats with anterior rectal resection (ARR). MATERIAL AND METHODS After establishment of rat ARR model, 20, 40 and 80 ug/ml ozone was used to treat rats by enema administration. The pathological examination of intestinal tissue was detected using hematoxylin-eosin staining. The rate of loose stools, minimum threshold volume of abdominal withdrawal reflex (AWR) and Bristol grade were used to evaluate the degree of abnormal defecation function. Subsequently, the levels of oxidative stress- and inflammation-related markers, 5-hydroxytryptamine (5-HT), inducible nitric oxide synthase (iNOS) and nitric oxide (NO) in the serum and intestinal tissue were determined with the corresponding kits. Meanwhile, the expression of nuclear factor kappa B (NF-κB) p65, transient receptor potential vanilloid (TRPV)1, TRPV4, iNOS and 5-HT receptor 3A (5-HTR3A) was determined with RT-qPCR and western blotting. RESULTS Ozone administration (20 and 40 ug/ml) significantly alleviated the pathological changes of intestinal tissue-induced by ARR, accompanied by the decreased loose stools rate, Bristol score and increased abdominal withdraw reflex. However, 80 ug/ml of ozone intervention played opposite roles in the aforementioned changes with 20 and 40 ug/ml of ozone. Additionally, remarkably elevated reactive oxygen species (ROS), malonaldehyde (MDA), superoxide dismutase (SOD), 5-HT, iNOS and NO levels were observed in the ozone-treated groups (20 and 40 ug/ml), while high dose of ozone drastically improved ROS, MDA, 5-HT, iNOS and NO levels but reduced the activity of SOD. Consistently, the contents of inflammatory factors were decreased after low and middle doses of ozone administration. However, high dose of ozone aggravated the inflammatory injury. Moreover, 20 and 40 ug/ml ozone upregulated TRPV1 and TRPV4 expression but downregulated 5-HTR3A expression, which was restored after 80 ug/ml of ozone intervention. Remarkably, the levels of NF-κB p65 and iNOS were dose-dependently enhanced following ozone treatment. CONCLUSIONS Taken together, low concentration of ozone attenuated intestinal injury induced by ARR via balancing oxidative stress and inflammation, but high concentration of ozone exacerbated the intestinal injury, which might be related to the 5-HT and TRPV signaling.

Abstract
This study aimed to investigate the protective effect of sinapic acid (SA) on biochemical and histopathological changes in an experimental testicular torsion-detorsion rat model. Twenty-four rats were randomised into four groups: sham group, ischemia/reperfusion (IR) group subjected to testicular torsion for 2 hr and then detorsion for 4 hr, and two groups treated with SA1 and SA2 (10 mg/kg and 20 mg/kg, by single intraperitoneal injection, 30 min before reperfusion). Serum testosterone, follicle-stimulating hormone (FSH), and luteinizing hormone (LH) were measured by an autoanalyzer, superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), malondialdehyde (MDA), protein carbonyl (PC), and nitric oxide (NO) oxidative stress parameters by spectrophotometric methods, and tumour necrosis factor (TNF-α), interleukin-1 beta (IL-1β), and interleukin 6 (IL-6) parameters by the Elisa method. In addition, immunohistochemical and histopathological examinations were performed on testicular tissues. There was no significant difference between the groups in terms of serum testosterone, FSH and LH levels (p > .05). SA significantly reduced increased testicular damage, oxidative stress, inflammation, cell death and also restored decreased antioxidant enzyme activities (p < .05). Pre-treatment of rats with SA reduced testicular dysfunction and morphological changes IRI. SA's antioxidant, anti-inflammatory, and antiapoptotic properties were found to be protective against testicular IR.

Abstract
Objective: Busulfan is one of the most common chemotherapeutic drugs and has the ability to induce apoptosis in testicular germ cells, which leads to infertility. In this study, the effects of ozone therapy and melatonin were evaluated on testicular disorders induced by busulfan. Methods: In this study, we divided 24 male mice into four groups: control group, groups treated with busulfan, busulfan/melatonin, and busulfan/ozone. At the end of a 35-day period, blood samples were taken from the mice and their testosterone levels were measured. Both of the mice’s testes were removed and weighed, afterwards, each one of them was used for evaluation of morphology by Johnson’s score, as well as for measuring the diameter and thickness of seminiferous tubules. The other testis was homogenized for measuring Malondialdehyde (MDA) and antioxidant status using Catalase (CAT), Super Oxide Dismutase (SOD), and Total Antioxidant Capacity (TAC) levels. Epididymis spermatozoa were also used to evaluate motility, morphology, and sperm count. Results: Busulfan significantly reduced the testis quality (weight, sperm parameters, testosterone, CAT, SOD, and TAC levels) and increased MDA and destruction of seminiferous tubules compared to the control group. Ozone and melatonin treatments significantly increased testis quality, sperm parameters, MDA, and antioxidant status, but they did not affect the TAC level. Conclusions: This study showed that similar to melatonin, ozone can reduce the effect of busulfan toxicity on mice testis. However, further studies are needed to understand the precise mechanism of ozone function on testis.

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.

Abstract
The current treatment of leishmaniasis presents some problems, such as cell toxicity, parenteral route, and time of treatment. Ozone emerges as an option to accelerate the standard treatment due to the immunomodulatory, antioxidant, and wound healing activity reported in the literature. This work aimed to evaluate the efficacy of aqueous ozone as an adjuvant to the standard treatment of cutaneous lesions caused by Leishmania amazonensis in an experimental model. For in vivo experiments, mice were randomly distributed in 6 groups, which were infected with L. amazonensis and treated in five different schedules using the standard treatment with Glucantime® with or without aqueous ozone. After the last day of treatment, the animals were euthanized and were analyzed: the thickness of lesions; collagen deposition, the parasitic burden of the lesions; blood leukocyte number; NO; and cytokine dosages and arginase activity from peritoneal macrophages. All treated groups showed a decrease in the lesion, but with a significative deposition of collagen in lesions with local ozone treatment. The parasite burden showed that ozone enhanced the leishmanicidal activity of the reference drug. The reduction of NO production and blood leukocyte count and increases in the arginase activity showed an immunomodulatory activity of ozone in the treated animals. Thus, ozone therapy has been shown to work as an adjuvant in the treatment of Leishmania lesions, enhancing leishmanicidal and wound healing activity of standard treatment.

Abstract
Testicular torsion is an emergency, and unless there is an urgent intervention, irreversible ischaemic damage and gonad loss occur in the testicle. We aimed to investigate myricetin's antioxidant properties as well as its protective effect against ischaemia-reperfusion (I/R) damage in the testicular torsion model. A total of 18 rats were divided into three equal groups. Group 1 was the sham group. Group 2: testicular torsion was performed, and orchiectomy was done 2 hr after detorsion. Group 3: received torsion and 1 mg/kg intraperitoneal myricetin was given 30 min before detorsion, and orchiectomy was applied 2 hr after detorsion. We evaluated tissue malondialdehyde, superoxide dismutase, and catalase levels and Johnsen Testicular Biopsy Score to show its histopathological effect. There was a statistically significant decrease in MDA values in myricetin group compared to Group 2 (p < .017). There was no significant difference in the statistical analysis of SOD and CAT values (p = .337 and p = .025). There was a statistically significant difference in testicular I/R damage in the myricetin group compared to Group 1 and Group 2 (p < .017). Myricetin treatment significantly decreased testicular tissue damage compared to the torsion group but did not reach the values close to the control group.

Abstract
Medical ozone is used to treat various diseases, including numerous pathologies associated with chronic pain. Chronic pain may be treated by systemic administration of ozone, with ozonated autohemotherapy (OAH) being the commonly used method. In the clinic, intravenous infusion of ozonized saline has been used to treat various diseases. Compared with OAH, ozonized saline infusion is less technically demanding and causes minimal damage to veins. However, it has been indicated that ozone may oxidize saline and generate toxic substances, and therefore, the safety of ozone treatment has been questioned. In the present study, the potential chemical compounds produced from ozone and saline, including chlorite, chlorate and perchlorate, were examined at various time-points with ion chromatography-mass spectrometry (IC-MS). A control group (pure oxygen group) and an ozone group were included in the present study. Two subgroups were included within each group: A saline bottle (made from polypropylene) subgroup and an ozone-resistant blood transfusion bag [made from medical polyvinyl chloride, di(2-ethyl) hexyl phthalate plasticized] subgroup. For the ozone group, 100 ml saline and 100 ml medical ozone at various concentrations (20, 40 or 60 µg/ml in pure oxygen) were injected into the saline bottle or blood bag, and for the control group, 100 ml of pure oxygen was injected into the saline bottle or blood bag. The presence and the content of chlorite, chlorate and perchlorate were determined at different time-points (3, 6 and 15 days after mixing) by IC-MS. Chlorate was detected in the ozone groups at three time-points and its content increased as the ozone concentration and the reaction time increased. Under the same conditions (the same ozone concentration and the same incubation time), the chlorate content (0.90±0.14-7.69±0.48 µg/l) in the blood bag subgroup was significantly lower than that in the saline bottle subgroup (45.23±6.14-207.6±15.63 µg/l). However, chlorite and perchlorate were not detected at any time-point in the two groups. In addition, in the control group (pure oxygen group), chlorite, chlorate and perchlorate were not detected at any time-point. These results indicate that ozone reacts with saline to produce chlorate. Ozone may also react with the polypropylene saline bottle to increase the chlorate content in the bottled solution. Due to a lack of toxicology studies of chlorate in blood, it remains elusive whether ozonated saline and chlorate at the range of 0.90±0.14-7.69±0.48 µg/l has any toxic effects. The potential toxicity of chlorate should be considered when ozonated saline is used for clinical infusions.

Abstract
This study was designed to investigate the protective effect of hypothermia and vitamin E on spermatogenic function after reduction of testicular torsion in rats. Ninety-six pure inbred male SD rats were divided into group A, B, C and D according to the principle of body weight and birth similarity, with 24 rats in each group. Four groups of rats were respectively twisted on the left testis to establish unilateral testicular torsion rats. Rats in groups A, B, C, D were respectively given normal saline, hypothermia therapy, vitamin E therapy, and hypothermia and vitamin E therapy. The superoxide dismutase (SOD) activity and malondialdehyde (MDA) content of the four groups were detected, and the correlation levels of inflammatory factors IL-1β, hs-CRP and related sex hormones luteinizing hormone (LH), follicle-stimulating hormone (FSH), total testosterone (T) were detected by ELISA. Apoptosis of spermatogenic cells of testis in the four groups was detected by flow cytometry. SOD activity and MDA content in groups B, C and D were significantly higher than those in group A, MDA content was significantly lower than that in group A (P<0.05), SOD activity in group D was higher than that in groups B and C, while MDA content was lower than that in groups B and C (P<0.05). The levels of IL-1β and hs-CRP in group A were much higher than those in groups B, C and D (P<0.05). LH and FSH levels in group A were significantly higher than those in groups B, C and D (P<0.05), and in group D were significantly lower than those in groups B and C (P<0.05). Apoptosis rate of spermatogenic cells in group A was significantly higher than that in groups B, C and D (P<0.05). Hypothermia combined with vitamin E can reverse testicular injury in rats and reduce the apoptosis rate of spermatogenic cells.

Abstract
We investigated the effects of ethyl pyruvate (EP) on oxidative and endoplasmic reticulum (ER) stress due to experimental testicular ischemia-reperfusion (I-R). Eighteen rats were divided into a control group, a torsion-detorsion (T-D) group and an EP group. For pretreatment of the EP group, 50 mg/kg EP was given intraperitoneally (i.p.) 30 min before detorsion. Tissue 4-hydroxynonenal (4-HNE) and 78-kDa glucose-regulated protein (GRP78) levels were determined using enzyme-linked immunosorbent assay (ELISA) kits. Tissue total oxidant status (TOS) and total antioxidant status were determined using colorimetric methods. Histology of the tissues was evaluated using hematoxylin and eosin staining. In the T-D group, tissue 4-HNE, GRP78, TOS and oxidative stress index levels were significantly higher than for the control group. The increases were reduced significantly by EP pretreatment. Our findings suggest that EP can inhibit I-R induced testicular injury by suppressing oxidative and ER stress. EP may be a useful adjunctive treatment for surgical repair in humans.

N-acetylcysteine protects testicular tissue against ischemia/reperfusion injury via inhibiting endoplasmic reticulum stress and apoptosis. J Pediatr Urol 2019; 15:253.e1-253.e8.

Abstract
BACKGROUND In animal models, endoplasmic reticulum (ER) stress has been reported to play a vital role in mediating ischemia/reperfusion (I/R) injury in certain organs, such as brain, liver, and intestine. However, there are a limited number of studies examining the relationship between ER stress and torsion and detorsion (T/D)-induced testicular injury. OBJECTIVE To investigate the effects of N-acetylcysteine (NAC) on ER-stress and apoptosis in an experimental testicular I/R injury model. DESIGN A non-blinded experimental study with three arms. Rats were divided into three groups: control group, T/D group, and NAC group. In the pretreatment of the NAC group, 20 mg/kg NAC was given intraperitoneally 30 min before detorsion. Tissue 4-hydroxynonenal (4-HNE), 78-kDa glucose-regulated protein (GRP78), and activating transcription factor 6 (ATF6) levels were determined using enzyme-linked immunosorbent assay. The apoptosis levels were evaluated using terminal deoxynucleotide transferase-mediated dUTP nick-end label assay. RESULTS In T/D group, tissue 4-HNE, GRP78, ATF6, and apoptotic index levels were significantly higher than control group. These increases were significantly reversed with NAC pretreatment. DISCUSSION There are some potential drugs that have been shown to reduce ER stress in the experimental ischemia model, and it is questioned that these drug candidates can be used as a therapeutic agent in the treatment of ischemic diseases in the near future. This study was not without limitations. First, the authors applied NAC only 20 mg/kg. In a future study, a dose-dependent assay should be performed to assess the likelihood of an additional testicular protective effect. One limitation of this research is also that in vivo studies cannot be extrapolated to possible effect in clinics. More experiments therefore need to be conducted to extrapolate the study findings to humans. CONCLUSION The study results showed that, after testicular torsion (TT), the ER stress-related apoptotic pathway plays a pivotal role in testicular injury. Further studies of other experimental models of TT may prove that NAC is a useful agent as an adjunctive treatment in surgical repair in human cases.

Abstract
Ozone-therapy initially applied in medicine by an empirical approach, has now reached a new stage where most of the biological mechanisms of ozone action have been clarified, that refers to antimicrobial effects, immunoregulation, antioxidant defenses and epigenetic modification. Current ozone medical preparation in dermatology mainly classified as ozone hydrotherapy, ozonated oil externally used and ozone autohemotherapy (OAHT). Admittedly, ozone is widely used in various fields against gram-negative and gram-positive bacteria, viruses, and fungi. More recently, great progress has been obtained in wound healing which is a multiphase process that consists of three overlapping but distinct stages: inflammation, tissue proliferation and remodeling. While the exact mechanisms of ozone-therapy still remain unclear. Therefore, more evidence is required before ozone can be presented as a promising method for the management and prevention of various skin diseases. In this review, we review the application status of ozone in dermatology and summarize possible mechanisms of ozone-therapy on skin diseases, aims to shed a light on providing a series of theoretical basis for its applications.
