Abstract
Objective Ischemia/reperfusion (I/R) may cause irreversible damage to tissues and organs. We evaluated the effects of dexketoprofen on a renal I/R model in rats. Methods The study included 30 male rats. Control group received 1 mL of saline. Dexketoprofen group received 1 mL (25 mg) of dexketoprofen intraperitoneally. After 60 minutes renal ischemia, 23 hours reperfusion was applied. In Sham group, laparotomy was performed with a medial line incision without any additional procedure. Changes in the plasma malondialdehyde (MDA), renal tissue MDA, plasma glutathione peroxidase (GPx), superoxide dismutase (SOD), catalase (CAT), BUN, creatinine and albumin levels, and histopathological changes were evaluated. Results CAT values were significantly lower in Control as compared with the Sham group. Plasma levels of MDA in the Control group were significantly higher than in the Dexketoprofen group. BUN and creatinine values were significantly higher in the Dexketoprofen group. The severity of tissue injury in the Dexketoprofen group was significantly higher than in Control and Sham groups Conclusion Although dexketoprofen reduces the I/R-induced systemic inflammation, it increases renal tissue damage.

Abstract
Significance: Endothelial cells lining the lumen of blood vessels play an important role in the regulation of cardiovascular functions through releasing both vasoconstricting and vasodilating factors. The production and function of vasoconstricting factors are largely elevated in hypertension, diabetes, atherosclerosis, and ischemia/reperfusion injuries. Cyclooxygenases (COXs) are the major enzymes producing five different prostanoids that act as either contracting or relaxing substances. Under conditions of increased oxidative stress, the expressions and activities of COX isoforms are altered, resulting in changes in production of various prostanoids and thus affecting vascular tone. This review briefly summarizes the relationship between oxidative stress, COXs, and prostanoids, thereby providing new insights into the pathophysiological mechanisms of cardiovascular diseases (CVDs). Recent Advances: Many new drugs targeting oxidative stress, COX-2, and prostanoids against common CVDs have been evaluated in recent years and they are summarized in this review. Critical Issues: Comprehensive understanding of the complex interplay between oxidative stress, COXs, and prostanoids in CVDs helps develop more effective measures against cardiovascular pathogenesis. Future Directions: Apart from minimizing the undesired effects of harmful prostanoids, future studies shall investigate the restoration of vasoprotective prostanoids as a means to combat CVDs.

Abstract
OBJECTIVE Although cisplatin (CIS) acts as potent chemotherapy, nephrotoxicity still its major life-threatening side effect. The purpose of this study was to discuss and compare the renoprotective effects of curcumin (CUR) and etoricoxib (ETB) against CIS-induced nephrotoxicity. MATERIALS & METHODS Thirty six adult female rats were divided equally into 6 groups: Group I (control), Group II (CIS) received cisplatin (7.5 mg/kg i.p), Group III (CUR) and group IV (ETB) received curcumin (200 mg/kg/day) or etoricoxib (10 mg/kg/day) respectively via gavage for seven continuous days. Group V (CIS + CUR) and Group VI (CIS + ETB) received curcumin (200 mg/kg/day) or etoricoxib (10 mg/kg/day) via gavage for seven continuous days. On the 4th day, the rats received cisplatin (7.5 mg/kg i.p) as a single injection 1 h after last curcumin or etoricoxib administration. At the assigned time, blood and tissue samples were collected for biochemical, histochemical, histopathological, immunohistochemical, and RT-PCR gene expression studies. RESULTS Curcumin administration significantly decreased CIS-induced elevation of serum creatinine and blood urea nitrogen (BUN), and reversed oxidative stress markers; glutathione (GSH) and malondialdehyde (MDA) to control level. Suppression of inflammatory and apoptotic responses by CUR co-treatment was evidenced by decreased iNOS and BAX immunohistochemical reactions, and TNF-α and Caspase3 gene expressions which were detected by RT-PCR in kidney tissues. To our knowledge, this is the first time to discuss the effect of ETB on CIS induced nephrotoxicity. Although ETB reduced the previously mentioned inflammatory and apoptotic markers, its effect was less than that of CUR. Administration of ETB couldn't modify the disturbed levels of creatinine, BUN, GSH, and MDA. CONCLUSION In conclusion, CUR provided a promising renoprotective effect against CIS induced nephrotoxicity. Further studies are recommended to approve or disapprove the protective role of ETB in CIS induced nephrotoxicity.

Abstract
The effect of rutin on ovarian ischemia-reperfusion (I/R) injury was investigated in this experimental study. Eighteen Wistar albino female rats were divided into three groups as follows: I/R group (IRG; n = 6), 50 mg/kg rutin + I/R group (RG; n = 6), and a healthy control group scheduled for a sham operation (SG; n = 6). 2 h of ischemia and following 2 h of reperfusion were created in the IRG and RG by using a torsion model involving atraumatic vascular clips. Rutin, a flavonoid glycoside, was injected intraperitoneally at the dose of 50 mg/kg to RG group 1 h before reperfusion. Then, rats were euthanized and their ovaries were removed for biochemical and histopathological examination and also assessment of the gene expressions. IRG group had a significant increase in malondialdehyde (MDA) levels, in the expressions of tumor necrosis factor alpha (TNF-α) and interleukin 1 beta (IL-1β), and also in the activity of cyclooxygenase 2 (COX-2) unlike the significant decrease in total glutathione (tGSH) levels and the activity of COX-1 when compared to the SG group. However, rutin significantly decreased MDA levels, the expressions of TNF-α and IL-1β, and also the activity of COX-2 while it increased significantly tGSH levels and the activity of COX-1 in the RG group in comparison with the IRG group. Rutin ameliorated the I/R-induced ovarian injury in rats via its possible antioxidative and anti-inflammatory effects.

Abstract
Etoricoxib features antioxidant and anti-inflammatory properties concomitantly, suggesting that it may be beneficial in testicular ischemia reperfusion (I/R) damage. Our aim is to investigate the effects of etoricoxib on testicular I/R damage induced with torsion-detorsion (TD). The etoricoxib + torsion-detorsion (ETD) groups of animals were given etoricoxib in 50 and 100 mg/kg of body weight (ETD-50 and ETD-100), while the testes torsion-detorsion (TTD) and sham operation rat group (SOG) animals were given single oral doses of distilled water as a solvent. TTD, ETD-50 and ETD-100 groups were subjected to 720° degrees torsion for four hours, and detorsion for four hours. The SOG group was not subjected to this procedure. Biochemical, gene expression and histopathological analyses were carried out on the testicular tissues. The levels of malondialdehyde (MDA), myeloperoxidase (MPO), interleukin-1 beta (IL-1β) and tumor necrosis factor alpha (TNF-α) were significantly higher, and the levels of total glutathione (tGSH) and glutathione reductase (GSHRd) were significantly lower in the TTD group, compared to the ETD-50, ETD-100 and SOG groups. Etoricoxib at a dose of 100 mg/kg better prevented I/R damage than the 50 mg/kg dose. Etoricoxib may be useful in clinical practice in the reduction of I/R damage on testes caused by torsion-detorsion.

Abstract
Hepatic ischemia-reperfusion (I/R) injury is a serious complication in clinical practice. However, no efficient biomarkers are available for the evaluation of the severity of I/R injury. Recently, renalase has been reported to be implicated in the I/R injury of various organs. This protein is secreted into the blood in response to increased oxidative stress. To investigate the responsiveness of renalase to oxidative stress, we examined the changes of renalase in cell and mouse models. We observed a significant increase of renalase expression in HepG2 cells in a time- and dose-dependent manner when treated with H2O2. Renalase expression also increased significantly in liver tissues that underwent the hepatic I/R process. The increased renalase levels could be efficiently suppressed by antioxidants in vitro and in vivo. Furthermore, serum renalase levels were significantly increased in the mouse models and also efficiently suppressed by antioxidants treatment. The variation trends are consistent between renalase and liver enzymes in the mouse models. In conclusion, renalase is highly sensitive and responsive to oxidative stress in vitro and in vivo. Moreover, renalase can be detected in the blood. These properties make renalase a highly promising biomarker for the evaluation of the severity of hepatic I/R injury.

Abstract
The cyclooxygenase (COX) enzyme system is the major pathway catalyzing the conversion of arachidonic acid into prostaglandins (PGs). PGs are lipid mediators implicated in a variety of physiological and pathophysiological processes in the kidney, including renal hemodynamics, body water and sodium balance, and the inflammatory injury characteristic in multiple renal diseases. Since the beginning of 1990s, it has been confirmed that COX exists in 2 isoforms, referred to as COX-1 and COX-2. Even though the 2 enzymes are similar in size and structure, COX-1 and COX-2 are regulated by different systems and have different functional roles. This review summarizes the current data on renal expression of the 2 COX isoforms and highlights mainly the role of COX-2 and PGE2 in several physiological and pathophysiological processes in the kidney.

Abstract
UNLABELLED Ischemia-reperfusion (I/R) damage is known to be a pathological process which continues with the increase of oxidants and expands with the inflammatory response. There is not any study about protective effect of etoricoxib on the liver I/R damage in literature. OBJECTIVE This study investigates the effect of etoricoxib on oxidative stress induced by I/R of the rat liver. MATERIAL AND METHODS Experimental animals were divided into four groups as liver I/R control (LIRC), 50 mg/kg etoricoxib + liver I/R (ETO-50), 100 mg/kg etoricoxib + liver I/R (ETO-100), and healthy group (HG). ETO-50 and ETO-100 groups were administered etoricoxib, while LIRC and HG groups were orally given distilled water by gavage. Hepatic artery was clamped for one hour to provide ischemia, and then reperfusion was provided for 6 hours. Oxidant, antioxidant, and COX-2 gene expressions were studied in the liver tissues. ALT and AST were measured. RESULTS Etoricoxib in 50 and 100 mg/kg doses changed the levels of oxidant/antioxidant parameters such as MDA, MPO, tGSH, GSHRd, GST, SOD, NO, and 8-OH/Gua in favour of antioxidants. Furthermore, etoricoxib prevented increase of COX-2 gene expression and ALT and AST levels. This important protective effect of etoricoxib on the rat liver I/R can be tested in the clinical setting.
