Targeting Mitochondrial Dynamics during Lower-Limb Ischemia Reperfusion in Young and Old Mice: Effect of Mitochondrial Fission Inhibitor-1 (mDivi-1). Int J Mol Sci 2024; 25:4025. [PMID: 38612835 PMCID: PMC11012338 DOI: 10.3390/ijms25074025] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2024] [Revised: 03/25/2024] [Accepted: 04/01/2024] [Indexed: 04/14/2024] Open
Abstract
Peripheral arterial disease (PAD) strikes more than 200 million people worldwide and has a severe prognosis by potentially leading to limb amputation and/or death, particularly in older patients. Skeletal muscle mitochondrial dysfunctions and oxidative stress play major roles in this disease in relation with ischemia-reperfusion (IR) cycles. Mitochondrial dynamics through impairment of fission-fusion balance may contribute to skeletal muscle pathophysiology, but no data were reported in the setting of lower-limb IR despite the need for new therapeutic options. We, therefore, investigated the potential protective effect of mitochondrial division inhibitor-1 (mDivi-1; 50 mg/kg) in young (23 weeks) and old (83 weeks) mice submitted to two-hour ischemia followed by two-hour reperfusion on systemic lactate, muscle mitochondrial respiration and calcium retention capacity, and on transcripts specific for oxidative stress and mitochondrial dynamics. At the systemic levels, an IR-related increase in circulating lactate was still major despite mDivi-1 use (+305.9% p < 0.0001, and +269.4% p < 0.0001 in young and old mice, respectively). Further, IR-induced skeletal muscle mitochondrial dysfunctions (more severely impaired mitochondrial respiration in old mice (OXPHOS CI state, -68.2% p < 0.0001 and -84.9% p < 0.0001 in 23- and 83-week mice) and reduced calcium retention capacity (-46.1% p < 0.001 and -48.2% p = 0.09, respectively) were not corrected by mDivi-1 preconditioning, whatever the age. Further, mDivi-1 treatment did not oppose superoxide anion production (+71.4% p < 0.0001 and +37.5% p < 0.05, respectively). At the transcript level, markers of antioxidant enzymes (SOD 1, SOD 2, catalase, and GPx) and fission markers (Drp1, Fis) remained unchanged or tended to be decreased in the ischemic leg. Fusion markers such as mitofusin 1 or 2 decreased significantly after IR in both groups. In conclusion, aging enhanced the deleterious effects or IR on muscle mitochondrial respiration, and in this setting of lower-limb IR, mDivi-1 failed to protect the skeletal muscle both in young and old mice.

N-acetylcysteine treatment attenuates hemodialysis access-related limb pathophysiology in mice with chronic kidney disease. Am J Physiol Renal Physiol 2023; 325:F271-F282. [PMID: 37439200 PMCID: PMC10511162 DOI: 10.1152/ajprenal.00083.2023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/03/2023] [Revised: 06/20/2023] [Accepted: 07/05/2023] [Indexed: 07/14/2023] Open
Abstract
The objective of the present study was to determine if treatment with N-acetylcysteine (NAC) could reduce access-related limb dysfunction in mice. Male and female C57BL6J mice were fed an adenine-supplemented diet to induce chronic kidney disease (CKD) prior to the surgical creation of an arteriovenous fistula (AVF) in the iliac vascular bundle. AVF creation significantly increased peak aortic and infrarenal vena cava blood flow velocities, but NAC treatment had no significant impact, indicating that fistula maturation was not impacted by NAC treatment. Hindlimb muscle and paw perfusion recovery and muscle capillary density in the AVF limb were unaffected by NAC treatment. However, NAC treatment significantly increased the mass of the tibialis anterior (P = 0.0120) and soleus (P = 0.0452) muscles post-AVF. There was a significant main effect of NAC treatment on hindlimb grip strength at postoperative day 12 (POD 12) (P = 0.0003), driven by significantly higher grip strength in both male (P = 0.0273) and female (P = 0.0031) mice treated with NAC. There was also a significant main effect of NAC treatment on the walking speed at postoperative day 12 (P = 0.0447), and post hoc testing revealed an improvement in NAC-treated male mice (P = 0.0091). The area of postsynaptic acetylcholine receptors (P = 0.0263) and motor endplates (P = 0.0240) was also increased by NAC treatment. Interestingly, hindlimb skeletal muscle mitochondrial oxidative phosphorylation trended higher in NAC-treated female mice but was not statistically significant (P = 0.0973). Muscle glutathione levels and redox status were not significantly impacted by NAC treatment in either sex. In summary, NAC treatment attenuated some aspects of neuromotor pathology in mice with chronic kidney disease following AVF creation.NEW & NOTEWORTHY Hemodialysis via autogenous arteriovenous fistula (AVF) is the preferred first-line modality for renal replacement therapy in patients with end-stage kidney disease. However, patients undergoing AVF surgery frequently experience a spectrum of hand disability symptoms postsurgery including weakness and neuromotor dysfunction. Unfortunately, no treatment is currently available to prevent or mitigate these symptoms. Here, we provide evidence that daily N-acetylcysteine supplementation can attenuate some aspects of limb neuromotor function in a preclinical mouse model of AVF.

Abstract
Long-time ischemia worsening transplant outcomes in vascularized composite allotransplantation (VCA) is often neglected. Ischemia-reperfusion injury (IRI) is an inevitable event that follows reperfusion after a period of cold static storage. The pathophysiological mechanism activates local inflammation, which is a barrier to allograft long-term immune tolerance. The previous publications have not clearly described the relationship between the tissue damage and ischemia time, nor the rejection grade. In this review, we found that the rejection episodes and rejection grade are usually related to the ischemia time, both in clinical and experimental aspects. Moreover, we summarized the potential therapeutic measures to mitigate the ischemia-reperfusion injury. Compare to static preservation, machine perfusion is a promising method that can keep VCA tissue viability and extend preservation time, which is especially beneficial for the expansion of the donor pool and better MHC-matching.

Abstract
Extended tourniquet application, often associated with battlefield extremity trauma, can lead to severe ischemia-reperfusion (I/R) injury in skeletal muscle. Particulate oxygen generators (POGs) can be directly injected into tissue to supply oxygen to attenuate the effects of I/R injury in muscle. The goal of this study was to investigate the efficacy of a sodium percarbonate (SPO)-based POG formulation in reducing ischemic damage in a rat hindlimb during tourniquet application. Male Lewis rats were anesthetized and underwent tourniquet application for 3 h at a pressure of 300 mmHg. Shortly after tourniquet inflation, animals received intramuscular injections of either 0.2 mg/mL SPO with catalase (n = 6) or 2.0 mg/mL SPO with catalase (n = 6) directly into the tibialis anterior (TA) muscle. An additional Tourniquet-Only group (n = 12) received no intervention. Functional recovery was monitored by in vivo contractile testing of the hindlimb at 1, 2, and 4 wk after injury. By the 4 wk time point, the Low-Dose POG group continued to show improved functional recovery (85% of baseline) compared with the Tourniquet-Only (48%) and High-Dose POG (56%) groups. In short, the low-dose POG formulation appeared, at least in part, to mitigate the impact of ischemic tissue injury, thus improving contractile function after tourniquet application. Functional improvement correlated with maintenance of larger muscle fiber cross-sectional area and the presence of fewer fibers containing centrally located nuclei. As such, POGs represent a potentially attractive therapeutic solution for addressing I/R injuries associated with extremity trauma.NEW & NOTEWORTHY Skeletal muscle contraction was evaluated in the same animals at multiple time points up to 4 wk after injury, following administration of particulate oxygen generators (POGs) in a clinically relevant rat hindlimb model of tourniquet-induced ischemia. The observed POG-mediated improvement of muscle function over time confirms and extends previous studies to further document the potential clinical applications of POGs. Of particular significance in austere environments, this technology can be applied in the absence of an intact circulation.

Abstract
BACKGROUND Ischemia-reperfusion injury in free flaps is associated with tissue damage and is one of the main factors causing flap failure in reconstructive microsurgery. The aim of this study is to assess whether any ischemia-reperfusion injury takes place during a microsurgical flap reconstruction as seen through the levels of malondialdehyde (MDA) and superoxide dismutase, biomarkers of oxidative stress, and to analyze the effect of lidocaine in this process. METHODS Twenty-four patients operated for immediate breast reconstruction using the Deep Inferior Epigastric Perforator free flap technique were divided into two groups: one group was treated with a lidocaine intravenous perfusion and the other group with a saline perfusion. MDA and superoxide dismutase (SOD) levels were measured at several points before, during, and after surgery. RESULTS There was an increase in MDA levels in both groups, but the lidocaine group experienced a decrease during reperfusion. On the other hand, we observed a rise in SOD levels in both groups, but a decrease during reperfusion in the placebo group. However, these differences between groups were not statistically significant. CONCLUSIONS The decreased SOD activity and increased MDA content in our research prove a redox imbalance and high reactive oxygen species levels in flaps, indicating that tissues experience ischemia-reperfusion injury during microsurgical reconstruction. Lidocaine may have a protective effect in free flap surgery, but our results were not statistically significant, so further studies will be required.

Abstract
BACKGROUND Ischemia-reperfusion injury plays an important role in flap failure. Ischemic preconditioning technique is the only proven method for preventing ischemia-reperfusion injury, but it is not used widely in daily practice because of difficulties such as prolonging the operation time, need for surgical experience, and increasing the risk of complications. This study has been performed with the assumption that piracetam may be a simple and inexpensive alternative to the preconditioning technique due to its antioxidant, antiaggregant, rheological, anti-inflammatory, antiapoptotic, cytoprotective, and immune modulating effects. METHODS Thirty-two rats were divided into four groups and latissimus dorsi musculocutaneous flaps were raised. No extra procedure was applied, and no treatment was given to the control group. Four hours of ischemia was created by clamping the thoracodorsal pedicle in the second group. The animals in the third group were treated with 10 minutes of ischemia and reperfusion periods as a preconditioning procedure before the 4 hours of ischemia. Animals in the fourth group received systemic piracetam 30 minutes before and 6 days after reperfusion. Nitric oxide and myeloperoxidase levels in serum and tissue, acute inflammatory cell response, and vascular proliferation in tissue were examined at the postoperative 24th hour and 10th day. RESULTS Myeloperoxidase activity in both preconditioning and piracetam groups, was significantly lower than the ischemia-reperfusion group. Acute inflammatory cell response was similarly decreased in both preconditioning and piracetam groups compared with ischemia-reperfusion group. Tissue measurements of nitric oxide were also significantly higher in both preconditioning and piracetam groups than in the ischemia-reperfusion group. However, vascular proliferation increased in the preconditioning group, while it did not show any significant change in the piracetam group. CONCLUSION This study shows that systemic piracetam treatment provides protection against ischemia-reperfusion injury in musculocutaneous flaps and can offer a simple and inexpensive alternative to the preconditioning technique.

N-acetylcysteine differentially regulates the populations of bone marrow and circulating endothelial progenitor cells in mice with limb ischemia. Eur J Pharmacol 2020; 881:173233.

Abstract
Endothelial progenitor cells (EPCs) are important to tissue repair and regeneration especially after ischemic injury, and very heterogeneous in phenotypes and biological features. Reactive oxygen species are involved in regulating EPC number and function. N-acetylcysteine (NAC) inhibits ischemia-induced reactive oxygen species formation and promotes ischemic limb recovery. This study was to evaluate the effect of NAC on EPC subpopulations in bone marrow (BM) and blood in mice with limb ischemia. Limb ischemia was induced by femoral artery ligation in male C57BL/6 mice with or without NAC treatment. EPC subpopulations, intracellular reactive oxygen species production, cell proliferation and apoptosis in BM and blood cells were analyzed at baseline, day 3 (acute ischemia) and 21 (chronic) after ligation. c-Kit+/CD31+, Sca-1+/Flk-1+, CD34+/CD133+, and CD34+/Flk-1+ were used to define EPC subpopulations. Limb blood flow, function, muscle structure, and capillary density were evaluated with laser Doppler perfusion imaging, treadmill test, and immunohistochemistry, respectively, at day 3, 7, 14 and 21 post ischemia. Reactive oxygen species production in circulating and BM mononuclear cells and EPCs populations were significantly increased in BM and blood in mice with acute and chronic ischemia. NAC treatment effectively blocked ischemia-induced reactive oxygen species production in circulating and BM mononuclear cells, and selectively increased EPC population in circulation, not BM, with preserved proliferation in mice with chronic ischemia, and enhanced limb blood flow and function recovery, while preventing acute ischemia-induced increase in BM and circulating EPCs. These data demonstrated that NAC selectively enhanced circulating EPC population in mice with chronic limb ischemia.

Abstract
Context Contamination of feedstuff with mixed mycotoxins is one of the frequent problems found in broiler chicken production, especially in tropical countries with a hot and humid climate, such as Thailand. Aims An in vivo study was conducted to examine the effects of Thunbergia laurifolia Linn. (TL) leaves on the growth performance, nutrient digestibility and antioxidant enzyme activity of broiler chicks fed naturally mycotoxin-contaminated feed. Methods In total, 375 1-day-old male Arbor Acre broilers were allotted into five experimental groups, with five replicates each (15 chicks per replicate). The experimental groups were mycotoxin-free basal corn–soybean diet (T1, control), diet with mixed mycotoxins (aflatoxin, fumonisins, tricothecene and ochratoxin, T2), T2 diet but supplemented with 1% (w/w) yeast glucomannan (GM, T3), T2 diet but supplemented with 2% (w/w) TL (T4) and T2 diet but supplemented with both 2% (w/w) TL and 1% (w/w) GM (T5). Feed intake, bodyweight gain, feed conversion ratio, mortality rate, nutrient digestibility and the activity of antioxidant enzymes were measured at Days 21 and 42. Key results Broilers in T4 and T5 groups had a significantly (P < 0.05) higher nutrient digestibility than those in the other groups at Day 42, while broilers in the T3, T4 and T5 groups had a significantly (P < 0.05) higher glutathione peroxidase activity than those in the other groups. There was no difference in the growth performance among the groups, except chicks that received the mixed mycotoxin-contaminated feed had a higher feed conversion ratio and ate more feed than did those in the control group. Conclusion It is concluded that 2% TL and 1% GM helped ameliorate the adverse effect of mycotoxin, improving nutrient digestibility and increased the glutathione peroxidase activity, but without a significant change in growth rate. Implications Herbal plant TL can be used as an alternative mycotoxin adsorbent in broiler production.

A natural polysaccharide scaffold, referred to as "freeze-dry nanogel-crosslinked-porous" (FD-NanoCliP) gel, was tested in comparison with an atelocollagen scaffold with respect to osteogenesis versus the mouse mesenchymal progenitor cell line KUSA-A1. The amphiphilic polysaccharide network, engineered in its structure to fit chemically crosslinked nanogels as building blocks into a physically crosslinked porous gel, revealed a superior osteointegrative performance as compared to the soluble atelocollagen network and a peculiar c-plane orientation growth of apatite crystallites, which resembled the structure of natural enamel. Besides evaluating osteogenesis in the FD-NanoCliP gel scaffold, an additional purpose of this study was to assess its chemical composition at the nanoscale and, through its knowledge, to interpret the osteogenic response of mesenchymal cells. In addition to conventional (optical and electron) microscopy and biological evaluation kits, the peculiar chemistry of the FD-NanoCliP gel scaffold and the formation of apatite on it were characterized by means of several independent analytical probes at the molecular scale, which included Raman, cathodoluminescence, energy dispersive X-ray, and X-ray fluorescence spectroscopies. This body of information consistently provided evidence for a peculiar chemistry developed in osteogenesis at the polysaccharide scaffold surface. Such chemistry is not available in soluble atelocollagen and it is key in the superior bioactivity found in the polysaccharide network.

Abstract
The aim of this study was to investigate the effect of boron on the repair of osteochondral defect and also on some antioxidant and oxidant parameters of both cartilage tissue and blood. A total of 24 adult male Wistar rats weighing between 350 and 400 g were used in the study. Animals were randomly divided into control (n = 8), boron (n = 8) and hyaluronic acid (HA) groups (n = 8). Under general anesthesia, a cylindrical full-thickness osteochondral defect 1.5 mm in diameter and 2 mm in depth was formed using a drill on the anterior side of the articular surface of the femur condyle. Boron group received 0.1 ml (10 mg/kg) of boron and HA group received 0.1 ml of HA, whereas control group received 0.1 ml of physiological saline solution. All agents administered intraarticular route and once a week for four times. At the end of the third month, the animals were euthanized and blood and joint tissue malondialdehyde (MDA), glutathione (GSH), superoxide dismutase (SOD), and catalase levels were measured. Defected femoral condyles of the rats were removed for a histopathological examination. Histopathology revealed that the total cartilage repair score of the HA group was better than those detected in boron and control groups. Blood and articular cartilage GSH, SOD, and catalase levels were higher in the boron and HA groups as compared to the control group, while MDA level was lower compared to the control group. In conclusion, it was suggested that boron was not as effective as HA in the repair of osteochondral defect, but its antioxidant property was superior to HA.

Abstract
Objective: Coenzyme Q10 (CoQ10) has antioxidant and anti-inflammatory activity. The aim of this study was to investigate the effects of CoQ10 on the inhibition of nuclear factor-kappa B (NF-κB) activation during ischemia-reperfusion (I/R) of skeletal muscle. Methods: For ischemia induction, the animals were anesthetized and the external iliac vessels blocked for three hours. CoQ10 or vehicle was given intraperitoneally during ischemia, just before reperfusion. Four groups received 3,7,14 and 28 days’ reperfusion, respectively, after the intraperitoneal injection of CoQ10 and four corresponding groups received vehicle only. After reperfusion, the gastrocnemius muscles were removed, fixed and stained for the analysis of edema and mast cell infiltration. Results: Immuno-histochemistry staining was performed for the detection of tumor necrosis factor alpha (TNF-α) and NF-κB. CoQ10-treated groups showed a significant decrease of mast cell infiltration in the gastrocnemius muscle and edema as compared with the corresponding non-treated groups. Also, CoQ10-treated groups showed a significant TNF-α and NF-κB expression decrease when compared to the corresponding non-treated controls. The results of this study showed CoQ10 administration with ischemia decreased interstitial edema, degeneration of muscle fibers and infiltration of mast cells. Conclusions: It seems that CoQ10 has inhibitory effects on NF-κB and TNF-α activation.

Abstract
In this study, we investigated the potential beneficial effects of quercetin on skeletal muscle ischemia reperfusion injury. Twenty-four Sprague-Dawley type rats were randomly divided into four groups. In the sham group, only gastrocnemius muscle were removed and given no quercetin. In ischemia group, all the femoral artery, vein and collaterals were occluded in the left hindlimb by applying tourniquate under general anaesthesia for three hours but reperfusion was not done. In the Quercetin + Ischemia reperfusion group, quercetin (200 mg kg-1 dose orally) was given during one-week reoperation and later ischemia reperfusion model was done. Finally, gastrocnemius muscle samples were removed to measure biochemical parameters. The biomarkers, MDA levels, SOD, CAT and GPx activities, were evaluated related to skeletal muscle ischemia reperfusion injury. MDA levels reduced and SOD, CAT and GPx activities increased significantly in Quercetin + Ischemia reperfusion group. Results clearly showed that Quercetin have a protective role against oxidative damage induced by ischemia reperfusion in rats.

Abstract
BACKGROUND Ischemia-reperfusion injury is inevitable during free-tissue transfer, causing oxidative damage and extensive apoptosis. Thioredoxin is an endogenous protein with antioxidant and antiapoptotic activity in a variety of tissues. This study aims to investigate the protective effects of human thioredoxin-1 on ischemia-reperfusion flaps, and its clinical application value. METHODS Sixteen clinical specimens of ischemia-reperfusion flaps were collected and assessed for apoptosis and thioredoxin-1 expression. Eighty mice were administered recombinant human thioredoxin-1 or saline intraperitoneally for 5 days before ischemia-reperfusion. Half of the mice were killed 24 hours after reperfusion. The flap tissues were harvested and detected for the changes of morphology, apoptosis, redox condition, and relative protein expression. The flap survival percentage of the remaining mice was consecutively observed within 7 days of reperfusion. RESULTS Thioredoxin-1 abundance was negatively correlated with ischemia-reperfusion-induced apoptosis in human samples and animal models. The survival rate of the ischemia-reperfusion flaps in mice increased significantly following recombinant human thioredoxin-1 pretreatment. Mitigated tissue damage, reduced apoptosis, and more antioxidant activity were observed in recombinant human thioredoxin-1-pretreated flaps. Western blot analysis revealed thioredoxin-1 depletion and a significant increase in apoptosis signal-regulating kinase 1, p-p38, and cleaved caspase-3 abundance in the ischemia-reperfusion flaps, whereas supplementation of recombinant human thioredoxin-1 significantly reduced the apoptosis-related protein expression. CONCLUSIONS Thioredoxin-1 exerts its flap-protective role through redox regulation of reactive oxygen species scavenging and antiapoptotic signaling. The authors' research provides evidence that thioredoxin-1 may serve as a potential prognostic and therapeutic target for skin flap ischemia-reperfusion injury.

Abstract
Inhalation anesthesia with isoflurane is a well-established and safe method used in small laboratory animals. In most cases oxygen is used as a carrier gas for isoflurane, but room air or mixtures of oxygen with air or nitrous oxide are also being used. Anesthesia is therefore administered using different fractions of inspired oxygen (FiO2), and this may have consequences for the outcome of experiments. The aim of the present study was to investigate the influence of FiO2 on rat hind limb ischemia/reperfusion injury and to refine the used inhalation anesthesia. Male Wistar rats were subjected to 3.5 h of ischemia and 2 h of reperfusion, and divided into three groups according to FiO2 in the O2/air/isoflurane anesthesia gas mixture: 40%, 60%, and 100% O2 Normal, healthy rats were used as controls. Muscle edema and creatine kinase MM, a marker for myocyte necrosis, were significantly increased with 40% FiO2 as compared with 100% FiO2 (P < 0.05). Partial pressure of oxygen, oxygen saturation, and oxyhemoglobin were significantly higher in the 100% O2 group as compared with 40% O2 No significant differences were detected for other parameters, such as the oxidative stress markers malondialdehyde and superoxide dismutase. We conclude that a refined inhalation anesthesia setting using 40% FiO2, reflecting more or less the clinical situation, leads to a more severe and more physiologically relevant reperfusion injury than higher FiO2. Oxidative stress did not correlate with FiO2 and seemed to have no influence on reperfusion injury.

Abstract
INTRODUCTION Ischemia-reperfusion injury (I-R) in skeletal muscle requires timely treatment. METHODS Rodent models of I-R injury were used to test the efficacy of recombinant human MG53 (rhMG53) protein for protecting skeletal muscle. RESULTS In a mouse I-R injury model, we found that mg53,-/- mice are more susceptible to I-R injury. rhMG53 applied intravenously to the wild-type mice protected I-R injured muscle, as demonstrated by reduced CK release and Evans blue staining. Histochemical studies confirmed beneficial effects of rhMG53. Of interest, rhMG53 did not protect against I-R injury in rat skeletal muscle. This was likely due to the fact that the plasma level of endogenous MG53 protein is high in rats. CONCLUSIONS Our data suggest that rhMG53 may be a potential therapy for protection against muscle trauma. A mouse model appears to be a better choice than a rat model for evaluating potential treatments for protecting skeletal muscle.

Abstract
BACKGROUND Ischemia-reperfusion of bone occurs in a variety of clinical conditions, such as orthopedic arthroplasty, plastic gnathoplasty, spinal surgery, and amputation. Usually, cellular models of hypoxia-reoxygenation reflect in vivo models of ischemia-reperfusion. With respect to hypoxia-reoxygenation conditions, the effects of remifentanil on osteogenesis have received little attention. Therefore, we investigated the effects of remifentanil on the proliferation and differentiation of osteoblasts during hypoxic-reoxygenation. METHODS After remifentanil (0.1, 1 ng/mL) preconditioning for 2 hours, human osteoblasts were cultured under 1% oxygen tension for 24 hours. Thereafter, the cells were reoxygenated for 12 hours at 37 °C. The naloxone groups were treated with naloxone for 30 minutes before remifentanil treatment. We measured cell viability via MTT assay. Osteoblast maturation was determined by assay of bone nodular mineralization. Quantitative PCR and western blot methods were used to determine BMP-2, osteocalcin, Akt, type I collagen, osterix, TGF-β1, HIF-1α, and RUNX2 expression levels. RESULTS Osteoblast viability and bone nodular mineralization by osteoblasts is recovered by remifentanil preconditioning from hypoxia-reoxygenation insult. During hypoxic-reoxygenation condition, remifentanil preconditioning induced the expression of BMP-2, osteocalcin, Akt, type I collagen, osterix, TGF-β1, HIF-1α, and RUNX2 in osteoblasts. CONCLUSIONS Under hypoxia-reoxygenation conditions, remifentanil preconditioning enhanced the cell viability and maturation of osteoblasts, and stimulated the expression of proteins associated with osteoblast proliferation and differentiation of the osteoblast. Our results suggest that remifentanil may help in the treatment of bone stress injuries.

Abstract
INTRODUCTION Skeletal muscle ischemia-reperfusion injury (I-R) is a complex injury process that includes damage to the sarcolemmal membrane, contributing to necrosis and apoptosis. MG53, a muscle-specific TRIM family protein, has been shown to be essential for regulating membrane repair and has been shown to be protective against cardiac I-R and various forms of skeletal muscle injury. The purpose of this study was to determine if recombinant human MG53 (rhMG53) administration offered protection against I-R. METHODS rhMG53 was administered to rats immediately before tourniquet-induced ischemia and again immediately before reperfusion. Two days later muscle damage was assessed histologically. RESULTS rhMG53 offered no protective effect, as evidenced primarily by similar Evans blue dye inclusion in the muscles of rats administered rhMG53 or saline. CONCLUSIONS Administration of rhMG53 does not offer protection against I-R in rat skeletal muscle. Additional studies are required to determine if the lack of a response is species-specific.

Abstract
BACKGROUND NSAIDs have been found to induce gastrointestinal tract damage. Recently, it has been suggested that this might be mediated by lipid peroxidation. OBJECTIVE The aim of this study was to assess the potential protective effects of β-glucan against acetylsalicylic acid (ASA-induced gastric damage by means of its antioxidant capacity in an experimental rat model. METHODS Thirty-two male Wistar albino rats (200-250 g) were randomized into 4 groups consisting of 8 rats each. The β-glucan group received 50 mg/kg β-glucan once a day for 10 days and 30 minutes before anesthesia. The ASA group received saline once a day for 10 days and 300 mg/kg (20 mg/mL) ASA as a single dose, 4 hours before anesthesia. The ASA+β-glucan group was administered 50 mg/kg β-glucan once a day for 10 days and 30 minutes before anesthesia. Additionally, 300 mg/kg (20 mg/mL) ASA was administered as a single dose, 4 hours before anesthesia. The control group received saline once a day for 10 days and 30 minutes before anesthesia. All medications were administered by intragastric gavage. The stomach from each rat was dissected and divided into 2 parts for histologic and biochemical analysis. Gastric tissue malondialdehyde (MDA), nitric oxide (NO) levels, catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px) activities were determined for oxidative parameter analysis. RESULTS The gastroprotective and antioxidant effects of β-glucan appeared to attenuate the ASA-induced gastric tissue damage. Compared with the control group, MDA and NO levels and CAT and GSH-Px activities were significantly increased in the stomachs of ASA-treated rats (MDA, 4.12 [0.44] to 13.41 [1.05] μmol/L; NO, 8.04 [7.25-9.10] vs 30.35 [22.34-37.95] μmol/g protein; CAT, 0.050 [0.004] to 0.083 [0.003] k/g protein; GSH-Px, 0.57 [0.42-0.66] to 1.55 [1.19-1.76] U/L; all, P < 0.001), whereas SOD activity was significantly decreased in the same group (291 [29] to 124 [6] U/mL; P < 0.001). In the ASA+β-glucan group, MDA and NO levels and CAT and GSH-Px activities were found to be significantly lower, while SOD activity was found to be significantly higher, in comparison with the ASA-treated group (all, P < 0.001). CONCLUSION β-Glucan appeared to attenuate the gastric damage caused by ASA in these rats.

[PMID: 24007817 DOI: 10.1016/j.jss.2013.07.052] [Citation(s) in RCA: 49] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/24/2013] [Revised: 07/14/2013] [Accepted: 07/26/2013] [Indexed: 02/08/2023]
Abstract
BACKGROUND Dexmedetomidine (DEX) has been shown to decrease ischemia-reperfusion (I/R) injury in kidney and brain tissues. In this study, the effects of DEX were evaluated in skeletal muscle during I/R injury. MATERIALS AND METHODS Animals were divided into four groups: sham-operated (sham group), saline + I/R, DEX + I/R, and α-tocopherol + I/R groups. Hind limb ischemia was induced by clamping the common femoral artery and vein. After 4 h of ischemia, the clamp was removed and the animals underwent 2 h of reperfusion. Animals in the drug treatment group received DEX or α-tocopherol by intraperitoneal injection 1 h before reperfusion. We measured plasma concentrations of interleukin 1β and tumor necrosis factor α levels using an enzyme-linked immunosorbent assay. The right gastrocnemius muscle was harvested and immediately stored at -80°C for the assessment of superoxide dismutase (SOD) and catalase (CAT) activities as well as glutathione (GSH), malondialdehyde (MDA), and protein oxidation (PO) levels. DEX (25 μg/kg) and normal saline (10 mL/kg) were administered by intraperitoneal injection 1 h before reperfusion. RESULTS Plasma tumor necrosis factor α or interleukin 1β levels increased significantly in the I/R group (P < 0.01 compared with sham group) and decreased significantly in the DEX group (P < 0.01 compared with I/R group). Muscle tissues of the I/R group had significantly decreased SOD, GSH, and CAT activities and increased levels of MDA and PO content compared with the sham group. The activity of antioxidant enzymes in the DEX + I/R group was greatly elevated compared with that in the I/R group (SOD, 1.068 ± 0.120 versus 0.576 ± 0.072 U/mg protein; GSH, 2.436 ± 0.144 versus 1.128 ± 0.132 μmol/g; and CAT, 69.240 ± 6.456 versus 31.884 ± 6.312 U/mg protein; P < 0.01), whereas the levels of MDA and PO content were clearly reduced (23.268 ± 3.708 versus 53.604 ± 5.972 nmol/g protein and 1.908 ± 0.192 versus 5.208 ± 0.612 nmol/mg protein, respectively; P < 0.01). Moreover, DEX exhibited more potent antioxidant activity than vitamin E in the skeletal muscle I/R. CONCLUSIONS We found that DEX exhibits protective effects against skeletal muscle I/R injury. These results underscore the necessity of human studies with DEX to determine if it is beneficial for preventing skeletal muscle I/R injury.

Abstract
OBJECTIVES To evaluate the acute effects of increased intra-abdominal pressure (IAP) on testicular germ cell apoptosis and the expressions of endothelial nitric oxide synthase (eNOS), inducible nitric-oxide synthase (iNOS), and Johnson's scores in testicular tissue. MATERIALS AND METHODS Twelve male pigs weighing 52 to 55 kg were divided into 2 groups as group 1 (n = 6; gasless [control]) and group 2 (n = 6; 20 mm Hg IAP with CO(2) pneumoperitoneum for 4 hours). In the second group, left laparoscopic nephrectomy was performed during the CO(2) insufflation period. The right testes of pigs were removed. Testicular germ cell apoptosis, expressions of eNOS and iNOS, and Johnson's scores were evaluated for each group. RESULTS The control group (group 1) exhibited low apoptotic cell level and low iNOS and eNOS level in testes. IAP (group 2) resulted in marked increases in germ cell apoptosis, eNOS, and iNOS compared with the control group (group 1) (P <.05). However, no significant difference was noted in Johnson's scores between the 2 groups (P >.05). Moreover, Leydig cell hyperplasia, congestion, and necrosis, which were not documented in the control group, were seen in the study group. CONCLUSIONS The purpose of the present study was to evaluate whether IAP could affect germ cell apoptosis and NOS concentrations in the testes after laparoscopic procedures in an animal model. In such an animal model simulating laparoscopic procedures, we demonstrated that high-pressure and long-lasting CO(2) insufflation cause testicular changes in the acute period.

Abstract
BACKGROUND To avoid ischemic necrosis, compartment syndrome is a surgical emergency treated with decompression once identified. A potentially lethal, oxidant-driven reperfusion injury occurs after decompression. N-acetylcysteine is an antioxidant with the potential to attenuate the reperfusion injury. QUESTIONS/PURPOSES We asked whether N-acetylcysteine could preserve striated muscle contractility and modify neutrophil infiltration and activation after simulated compartment syndrome release. MATERIALS AND METHODS Fifty-seven rats were randomized to control, simulated compartment syndrome, and simulated compartment syndrome plus N-acetylcysteine groups. We isolated the rodent cremaster muscle on its neurovascular pedicle and placed it in a pressure chamber. Chamber pressure was elevated above critical closing pressure for 3 hours to simulate compartment syndrome. Experiments were concluded at three times: 1 hour, 24 hours, and 7 days after decompression of compartment syndrome. We assessed twitch and tetanic contractile function and tissue myeloperoxidase activity. Ten additional rats were randomized to control and N-acetylcysteine administration after which neutrophil respiratory burst activity was assessed. RESULTS The simulated compartment syndrome decreased muscle contractility and increased muscle tissue myeloperoxidase activity compared with controls. Treatment with N-acetylcysteine preserved twitch and tetanic contractility. N-acetylcysteine did not alter neutrophil infiltration (myeloperoxidase activity) acutely but did reduce infiltration at 24 hours, even when given after decompression. N-acetylcysteine reduced neutrophil respiratory burst activity. CONCLUSION N-acetylcysteine administration before or after simulated compartment syndrome preserved striated muscle contractility, apparently by attenuating neutrophil activation and the resultant oxidant injury. CLINICAL RELEVANCE Our data suggest a potential role for N-acetylcysteine in the attenuation of muscle injury after release of compartment syndrome and possibly in the prophylaxis of compartment syndrome.

Abstract
BACKGROUND The aim of the study was to investigate effect of I/R injury on bone tissue and protective role of hyperbaric oxygen precondition (HBO-PC) and ozone precondition (O(3)-PC) on I/R injury by using biochemical analysis. MATERIALS AND METHODS Thirty-two rats were included in study. The animals were divided into four equal groups: sham operation, I/R, I/R+HBO and I/R+O(3). One session of 60 min, 3 ATA, 3-4 L/min, 100% oxygenation was defined as one dose of HBO. First dose of HBO was administrated 72 h before ischemia. Subsequent, one-dose of HBO administrated per 12 hours until ischemia time (total seven doses); 0.7 mg/kg ozone/oxygen mixture intraperitoneally was defined as one dose of ozone. First dose of O(3) was administered 72 h before ischemia (total four doses). I/R model was induced in anesthetized rats by unilateral (right) femoral artery clipping for 2 h followed by 22 h of reperfusion. The right tibia and were harvested. Tissue was assayed for levels of malondialdehyde (MDA) and protein carbonyl (PCO), activities of superoxide dismutase (SOD), and glutathione peroxidase (GSH-Px). RESULTS MDA and PCO levels were increased in I/R group. SOD activity was increased; GSH-Px activity was decreased in I/R group. MDA and PCO levels were decreased, SOD and GSH-Px activities were increased in both HBO+I/R and O(3)+I/R groups. CONCLUSION It has been shown that levels of MDA and PCO in bone were increased followed by 2 h of ischemia and 22 h of reperfusion period. Ozone-PC and HBO-PC has protective effect against skeletal bone I/R injury by decreasing levels of MDA and PCO, increasing activities of SOD and GSH-Px in rats.

Abstract
Abstract
Objectives
This work aimed to assess some pharmacological activities of coenzyme Q10 (CoQ10) in animal experimental models.
Methods
The chick chorioallantoic membrane assay was used to evaluate anti-angiogenic activity of CoQ10. Anti-inflammatory activity of CoQ10 was confirmed using two animal models of inflammation. These were the vascular permeability and air pouch models, models of acute and sub-acute inflammation, respectively. Antinociceptive activity was assessed by the acetic acid-induced abdominal constriction response.
Key findings
CoQ10 dose-dependently displayed inhibition of chick chorioallantoic membrane angiogenesis. In the acetic acid-induced vascular permeability model in mice, CoQ10 at 50, 100 and 200 mg/kg reduced vascular permeability from 0.74 ± 0.01 (A590) to 0.67 ± 0.01 (P < 0.01), 0.46 ± 0.02 (P < 0.01) and 0.30 ± 0.01 (P < 0.01), respectively. In the carrageenan-induced inflammation in the air pouch, CoQ10 was able to diminish exudate volume, the number of polymorphonulcear leucocytes and nitrite content in the air pouches. CoQ10 at 25, 50 and 100 mg/kg significantly reduced acetic acid-induced abdominal constriction in mice from 27.0 ± 2.00 (number of abdominal constrictions) to 17.7 ± 0.33 (P < 0.01), 9.3 ± 0.67 (P < 0.01) and 1.3 ± 0.33 (P < 0.01), respectively, suggesting a strong antinociceptive activity.
Conclusions
CoQ10 possessed considerable anti-angiogenic, anti-inflammatory and antinociceptive activity, possibly via down-regulating the level of nitric oxide, which partly supported its use as a dietary supplement and in combination therapy.

Abstract
BACKGROUND Transient limb ischemia induces remote early preconditioning that protects the myocardium from ischemia/reperfusion (I/R). However, it is unknown whether limb ischemia induces remote late preconditioning and whether it induces the same magnitude of cardioprotection compared with cardial ischemic preconditioning (CIP). We tested the hypothesis that late remote preconditioning of noninvasive limb ischemia (NLIP) offers the same magnitude of cardioprotection against myocardium I/R injury. METHODS Thirty Wistar rats weighing 240-260 g each were randomly divided into three groups: I/R, CIP, and NLIP. The mean arterial pressure (MAP), heart rate (HR), ST-segment, ventricular arrhythmia, and CK-MB, cTnI, and superoxide dismutase (SOD) activity were measured after 0 and 30 min of ischemia and after 120 min of reperfusion. Myocardial infarct size, histologic examination, MMP-2, MMP-9, and TIMP-1 protein expression were determined at the end of the experiment. RESULTS Compared with I/R groups, CIP and NLIP reduced ST-segment elevation (P<0.01), decreased incidence and duration of ventricular arrhythmia (P<0.01) during ischemia, decreased CK-MB (P<0.05), and cTnI (P<0.01) activity, and increased SOD (P<0.05) activity after reperfusion. The myocardial infarct size (P<0.01) was significantly reduced, and cell injury was attenuated in the CIP and NLIP groups compared with the I/R group. MMP-2 and MMP-9 protein expression was significantly decreased in the CIP and NLIP groups (P<0.01), while TIMP-1 expression was significantly increased in the CIP and NLIP groups compared with the I/R group (P<0.01). CONCLUSION Remote preconditioning via NLIP has late cardioprotection against myocardium I/R injury and has a similar magnitude of cardioprotection compared with CIP in rats.

Abstract
BACKGROUND AND OBJECTIVE The aim of this study was to compare the effects of propofol and N-acetyl cysteine (NAC) on tourniquet-induced ischaemia-reperfusion injury by determining malonyldialdehyde, ischaemia-modified albumin, lactate, blood gas and haemodynamic levels in arthroscopic knee surgery. METHODS Sixty ASA I or II patients were randomized into three groups. Intrathecal anaesthesia was administered using 0.5% heavy bupivacaine in all patients. In group P, propofol was administered in a 0.2 mg kg(-1) bolus, followed by infusion at a rate of 2 mg kg(-1) h(-1); in group NAC, NAC was administered as an infusion at a rate of 5 mg kg(-1) h(-1), and, in group C (the control group), an equal volume of isotonic saline was administered to patients until 30 min after reperfusion. Blood samplings were obtained immediately before intrathecal anaesthesia (t1), 1 min before tourniquet release (t2), 5 min after tourniquet release (t3) and 30 min after tourniquet release (t4). RESULTS Plasma malonyldialdehyde, ischaemia-modified albumin and lactate levels increased significantly in group C at t3 and t4 compared with the baseline values. Plasma concentrations of malonyldialdehyde, ischaemia-modified albumin and lactate in groups P and NAC were significantly lower than those in group C at t3 and t4. In blood gas analyses, pH, HCO3 and base excess were found to be significantly lower at t3 and t4 compared with t1 and t2 in group C. Comparisons between groups P and NAC revealed no significant differences. CONCLUSION Small-dose infusions of both propofol and NAC appear to provide similar protection against ischaemia-reperfusion injury in arthroscopic knee surgery.

Abstract
AIM: To investigate the protective effect of melatonin on liver after intestinal ischemia-reperfusion injury in rats.
METHODS: One hundred and fifty male Wistar rats, weighing 190-210 g, aged 7 wk, were randomly divided into melatonin exposure group, alcohol solvent control group and normal saline control group. Rats in the melatonin exposure group received intraperitoneal (IP) melatonin (20 mg/kg) 30 min before intestinal ischemia-reperfusion (IR), rats in the alcohol solvent control group received the same concentration and volume of alcohol, and rats in the normal saline control group received the same volume of normal saline. Serum samples were collected from each group 0.5, 1, 6, 12, and 24 h after intestinal IR. Levels of serum alanine aminotransferase (ALT) and aspartate aminotransferase (AST) were measured with an auto-biochemical analyzer. Serum TNF-α was tested by enzyme-linked immunosorbent assay (ELISA). Malondialdehyde (MDA) in liver was detected by colorimetric assay. Pathological changes in liver and immunohistochemical straining of ICAM-1 were observed under an optical microscope.
RESULTS: The levels of ALT measured at various time points after intestinal IR in the melatonin exposure group were significantly lower than those in the other two control groups (P < 0.05). The serum AST levels 12 and 24 h after intestinal IR and the ICAM-1 levels (%) 6, 12 and 24 h after intestinal IR in the melatonin exposure group were also significantly lower than those in the other two control groups (P < 0.05).
CONCLUSION: Exotic melatonin can inhibit the activity of ALT, AST and TNF-α, decrease the accumulation of MDA, and depress the expression of ICAM-1 in liver after intestinal IR injury, thus improving the liver function.

Abstract
Hydrogen peroxide (H2O2) and nitric oxide (NO) contribute to the pathogenesis of cerebral hypoxic-ischemic injury. We evaluated the neuroprotective effect of N-acetyl-l-cysteine (NAC, a free radical scavenger) against oxidative stress and perfusion in a model of neonatal hypoxia-reoxygenation (H-R). Piglets (1-3 d, 1.6-2.3 kg) were randomized into a sham-operated group (without H-R) (n = 5) and two H-R experimental groups (2 h normocapnic alveolar hypoxia followed by 4 h reoxygenation) (n = 7/group). Five minutes after reoxygenation, piglets were given either i.v. saline (H-R controls) or NAC (30 mg/kg bolus then 20 mg/kg/h infusion) in a blinded-randomized fashion. Heart rate, mean arterial pressure, carotid arterial blood flow (transit-time ultrasonic probe), cerebral cortical H2O2 and NO production (electrochemical sensor), cerebral tissue glutathione and nitrotyrosine levels (enzyme-linked immunosorbent assay) were examined. Hypoxic piglets were acidotic (pH 6.88-6.90), which recovered similarly in the H-R groups (p > 0.05 versus shams). Postresuscitation NAC treatment significantly attenuated the increase in cortical H2O2, but not NO, concentration during reoxygenation, with lower cerebral oxidized glutathione levels. NAC-treated piglets had significantly higher carotid oxygen delivery and lower cerebral lactate levels than that of H-R controls with corresponding changes in carotid arterial flow and vascular resistance. In newborn piglets with H-R, postresuscitation administration of NAC reduced cerebral oxidative stress and improved cerebral perfusion.
