Predictive Role of Neutrophil to Lymphocyte Ratio in Adnexal Torsion: A Systematic Review and Meta-Analysis. Mediators Inflamm 2022; 2022:9680591. [PMID: 36387932 DOI: 10.1155/2022/9680591] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2022] [Revised: 10/07/2022] [Accepted: 10/17/2022] [Indexed: 11/06/2022] Open
Abstract
Introduction. The goal of this systematic review and meta-analysis was to consolidate the available data on the role of the neutrophil to lymphocyte ratio (NLR) in predicting adnexal torsion (AT), to help guide clinical decision-making and outcomes. Methods. We used Web of Science, PubMed, and Scopus to conduct a systematic search for relevant publications published before June 26, 2022. We reported standardized mean difference (SMD) with a 95% confidence interval (CI). Because a significant level of heterogeneity was found, we used the random-effects model to calculate pooled effects. We used the Quality Assessment of Diagnostic Accuracy Studies 2 (QUADAS-2) too for quality assessment. Results. Overall, 15 articles were included in the analysis. A random-effects model revealed that patients with AT had elevated levels of NLR compared to those with other adnexal masses (
,
to 1.45,
). So, NLR had diagnostic value. In the subgroup analysis according to ethnicity, we found that Caucasian patients with AT had elevated levels of NLR compared to patients who were operated due to adnexal mass and reported as having a benign ovarian cyst, without torsion (
,
to 1.54,
). However, in the case of East Asian patients, there was no difference between cases and controls (
,
to 1.94,
). The pooled sensitivity of NLR was 0.79 (
), and the pooled specificity was 0.84 (95% CI, 0.74–0.91). Conclusion. In conclusion, there has been an interest in the use of NLR as a diagnostic marker for AT.

Mechanistic perspective of protective effects of resveratrol against cisplatin-induced ovarian injury in rats: emphasis on anti-inflammatory and anti-apoptotic effects. Naunyn Schmiedebergs Arch Pharmacol 2019; 392:1225-1238. [PMID: 31129703 DOI: 10.1007/s00210-019-01662-x] [Citation(s) in RCA: 17] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2018] [Accepted: 05/02/2019] [Indexed: 12/18/2022]
Abstract
Chemotherapeutic platinum-containing drugs are widely used to treat a variety of cancer types; however, they cause ovarian failure and infertility. The aim of this study is to investigate the molecular mechanism underlying the potential protective effect of resveratrol against cisplatin-induced ovarian damage in a rat model. Female rats were given either cisplatin (6 mg/kg, i.p., once per week for two consecutive weeks) and/or resveratrol (10 mg/kg, orally for 17 days). Follicular development, ovarian function markers, as well as apoptotic and inflammatory markers were assessed 24 h after the last resveratrol dose. Resveratrol ameliorated the marked follicular loss and the significant reduction in anti-Müllerian hormone (AMH) level triggered by cisplatin. Mechanistically, cisplatin elicited a potent inflammatory response in ovarian tissue as evidenced by the elevated expression of tumor necrosis factor, nuclear factor kappa-B, and proinflammatory enzymes. Co-treatment with resveratrol inhibited the elevation in inflammatory mediators induced by cisplatin. Further, cisplatin switched on the apoptotic machinery in ovarian tissues via increasing the expression of both cytochrome c and caspase-3 which was reversed upon resveratrol co-treatment. Resveratrol also counteracts the upregulating poly(ADP-ribose) polymerase expression which could attribute to the inflammatory and apoptotic effects of cisplatin. Resveratrol protects the ovary from cisplatin-induced toxicity through preventing the loss of the AMH-secreting granulosa cells, diminishing PARP-1 expression, and downregulating the inflammatory and apoptotic events implicated in cisplatin toxicity.

THE KOREAN JOURNAL OF PHYSIOLOGY & PHARMACOLOGY : OFFICIAL JOURNAL OF THE KOREAN PHYSIOLOGICAL SOCIETY AND THE KOREAN SOCIETY OF PHARMACOLOGY 2017; 21:457-464. [PMID: 28883750 PMCID: PMC5587596 DOI: 10.4196/kjpp.2017.21.5.457] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/16/2016] [Revised: 08/30/2016] [Accepted: 09/09/2016] [Indexed: 12/11/2022]
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.

Resveratrol inhibits inflammatory signaling implicated in ionizing radiation-induced premature ovarian failure through antagonistic crosstalk between silencing information regulator 1 (SIRT1) and poly(ADP-ribose) polymerase 1 (PARP-1). Biochem Pharmacol 2016; 103:140-50. [PMID: 26827941 DOI: 10.1016/j.bcp.2016.01.019] [Citation(s) in RCA: 76] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/06/2015] [Accepted: 01/25/2016] [Indexed: 01/28/2023]
Abstract
This study hypothesized that resveratrol, a silencing information regulator 1 (SIRT1) activator, would counteract the inflammatory signaling associated with radiotherapy-induced premature ovarian failure (POF). Immature female Sprague-Dawley rats were subjected to a single dose of γ-radiation to induce POF and treated with resveratrol (25mg/kg) once daily for two weeks before and three days post irradiation. Resveratrol preserves the entire ovarian follicle pool manifested by increasing serum anti-Müllerian hormone (AMH) levels. Radiation triggered inflammatory process in the ovary through enhanced NF-κB and poly(ADP-ribose) polymerase (PARP)-1 expression which convinced the expression of inflammatory markers including IL-6, IL-8, and visfatin mRNA levels, as well as inducible nitric oxide synthase and cyclooxygenase-2 protein expression with a concomitant reduction in IL-10 mRNA levels. Resveratrol significantly counteracted the effect of radiation and upregulated the gene expression of peroxisome proliferator-activated receptor γ (PPAR-γ) and SIRT1. Resveratrol-activated SIRT1 expression was associated with inhibition of PARP-1 and NF-κB expression-mediated inflammatory cytokines. Our findings suggest that resveratrol restored ovarian function through increasing AMH levels, and diminishing ovarian inflammation, predominantly via upregulation of PPAR-γ and SIRT1 expression leading to inhibition of NF-κB provoked inflammatory cytokines.

Abstract
AIM To evaluate the antioxidant effects of thymoquinone (TQ) and to investigate the biochemical, histopathological and immunohistochemical changes in experimental rat ovarian torsion. METHODS A total of 48 female adult rats were used in this study and randomly divided into 7 groups: (1) sham operation; (2) bilateral 3-hour ovarian ischemia; (3) 3-hour ischemia and 3-hour reperfusion; (4) and (5) rats were administered 20 and 40 mg/kg of TQ, respectively, before 0.5 h of ischemia, and then 3 h of ovarian ischemia was applied; (6) and (7) 3-hour ovarian ischemia was applied; 2.5 h after the induction of ischemia, rats were administered the same doses of TQ; at the end of 3 h of ischemia, a 3-hour reperfusion was applied. Histologic changes under light microscopy, immunoreactivity for anticaspase-3 and serum levels of malondialdehyde, interleukin-6, catalase and glutathione peroxidase were noted and compared between the 7 groups. RESULTS Ischemia and ischemia/reperfusion cause a deterioration of biochemical and histopathological parameters. Administration of TQ seems to reverse these alterations and alleviate the injury. Antioxidant defense mechanisms appear to be enhanced by the administration of TQ. CONCLUSION TQ at different doses attenuates ovarian ischemia and ischemia/reperfusion injury in rats.

Abstract
Ischemia-reperfusion injury is a significant problem following reperfusion treatment for ovarian torsion. It is generally caused by reactive oxygen species-induced damage. Antioxidant agents, such as curcumin, may protect ovaries from this adverse effect. The aim of the present randomized, controlled study was to evaluate the short-term protective effect of curcumin on a rat model of ovarian ischemia-reperfusion injury. A total of 30 female Wistar albino rats, weighing 160-230 g, were divided into 2 groups depending upon the time of unilateral, left ovary ischemia/reperfusion (group 1, 2 h ischemia/2 h reperfusion and group 2, 4 h ischemia/4 h reperfusion). These groups were subdivided into 3 subgroups (sham, control and curcumin). The sham subgroups were not subjected to ischemia/reperfusion. Control and curcumin subgroups were performed under ischemia for 2 h plus 2 h reperfusion or 4 h ischemia plus 4 h reperfusion. Curcumin, 200 mg/kg, was intraperitoneally administered simultaneously with reperfusion to the curcumin subgroups. Serum nitric oxide (NO), NO synthase (NOS), xanthine oxidase (XO), total antioxidant status (TAS), total oxidant status (TOS) and histological scores were measured and compared between subgroups. For group 1, no significant differences were observed between NO, NOS, XO, TAS or TOS. The left ovary histological grade was significantly higher in the control and curcumin subgroups compared with the sham subgroup (P=0.036). For group 2, TOS was significantly higher in the control group compared with the sham and curcumin groups (P=0.023). However, TAS was also significantly higher in the control subgroup compared with the other 2 subgroups (P=0.005). Left ovary histological grade was significantly higher in the control and curcumin subgroups compared with the sham subgroup (P=0.038). No significant differences were observed between NO, NOS or XO between the group 2 subgroups. The results showed that curcumin exerted no major significant protective effect on ischemia-reperfusion injury in the rat ovary.

The Effect of Etoricoxib on Hepatic Ischemia-Reperfusion Injury in Rats. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2015; 2015:598162. [PMID: 26236425 PMCID: PMC4506808 DOI: 10.1155/2015/598162] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/28/2015] [Accepted: 06/16/2015] [Indexed: 11/17/2022]
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.
