Abstract
The aim of this study was to determine the possible therapeutic effect of chlorogenic acid (CGA) on cisplatin (CDDP)-induced ovarian damage in rats. Rats were first exposed to CDDP (5 mg/kg) and then treated CGA (1.5 and 3 mg/kg) for three days. Oxidative stress (OS), inflammation and apoptosis markers were determined using spectrophotometric methods. Ovarian tissues were also evaluated histologically. The levels of OS, inflammation and apoptosis biomarkers increased by CDDP administration (p < 0.05). Treatments with CGA significantly alleviated these markers dose-dependently (p < 0.05). These data reveal that CGA may exert an ovoprotective effect by reducing pro-inflammatory mediators and enhancing antioxidant status in ovarian tissue.

Abstract
Although cisplatin (CDDP) is an antineoplastic drug widely used for the treatment of various tumors, its toxicity on the reproductive system is a concern for patients. Ethyl pyruvate (EP) possesses potent antioxidant and anti-inflammatory activities. The objective of this study was to evaluate the therapeutic potential of EP on CDDP-mediated ovotoxicity for the first time. Rats were exposed to CDDP (5 mg/kg) and then treated with two doses of EP (20 and 40 mg/kg) for 3 days. Serum fertility hormone markers were evaluated using ELISA kits. Oxidative stress (OS), inflammation, endoplasmic reticulum stress (ERS) and apoptosis markers were also determined. In addition, how CDDP affects the nuclear factor erythroid 2-associated factor 2 (Nrf2) pathway and the effect of EP on this situation were also addressed. EP improved CDDP-induced histopathological findings and restored decreasing levels of fertility hormones. EP treatment also reduced the levels of CDDP-mediated OS, inflammation, ERS and apoptosis. In addition, EP attenuated CDDP-induced suppression in the levels of Nrf2 and its target genes, including heme oxygenase-1, NAD(P)H quinone dehydrogenase-1, superoxide dismutase and glutathione peroxidase. Histological and biochemical results showed that EP can have therapeutic effects against CDDP-induced ovotoxicity with antioxidant, anti-inflammatory and Nrf2 activator activities.

Abstract
BACKGROUND Reproductive toxicity is one of the most important side effects of cisplatin (CIS) and leading to discontinuation of treatment. Syringic acid (SA) is a phenolic acid whose industrial use has increased in recent years due to its antioxidant properties. Recent reports highlight the importance of the supressed Nrf2 pathway in the molecular pathogenesis of CIS toxicity. Therefore, this study aimed to evaluate the therapeutic effect of SA on CIS-induced ovotoxicity through the Nrf2 pathway for the first time. MATERIAL AND METHODS Thirty female rats were divided into 5 groups: control, CIS, CIS+SA (5 and 10 mg/kg) and only SA (per se, 10 mg/kg). CIS was administered intraperitoneally at a dose of 5 mg/kg on the 1st day, injections of SA followed by three consecutive days in the rats. Serum anti-mullerian hormone (AMH) levels and ovarian oxidative stress (OS), inflammation, endoplasmic reticulum stress (ERS), apoptosis and Nrf2 pathway markers were determined colorimetrically. Histopathological examinations of the ovaries with hematoxylin and eosin staining were also used to evaluate CIS-induced ovotoxicity. RESULTS The CIS treatment depleted serum AMH levels, caused histopathological findings and increased OS, inflammation, ERS and apoptosis levels in ovarian tissue. However, treatments with SA significantly ameliorated CIS-induced biochemical and histopathological changes by activating Nrf2 pathway. CONCLUSION The promising adjuvant potential of SA to alleviate CIS-related ovarian damage should be supported by more comprehensive studies.

Abstract
PURPOSE Testicular toxicity is one of the most important side effects of cisplatin (CP) therapy. Alpha-pinene (AP) is a naturally occurring monoterpene with antioxidant character in plants. Here, we aimed to evaluate the therapeutic activity of AP against CP-induced testicular toxicity by including the nuclear factor erythroid 2-associated factor 2 (Nrf2) pathway in rats. METHODS Thirty male rats were divided into 5 groups: control, CP, CP + AP (5 and 10 mg/kg) and only AP (10 mg/kg). CP was administered intraperitoneally at a dose of 5 mg/kg on the first day, followed by three consecutive injections of AP. Serum reproductive hormone levels were evaluated using ELISA kits. Oxidative stress (OS), inflammation, endoplasmic reticulum stress (ERS) and apoptosis markers in testicular tissue were also determined colorimetrically. In addition, how CP affects Nrf2 pathway and the effect of AP on this situation were also addressed. RESULTS Treatment with CP significantly increased OS, inflammation, ERS and apoptosis in testicular tissue. Administrations of AP resulted in an amelioration of these altered parameters. The mechanism of therapeutic effect of AP appeared to involve induction of Nrf2. Furthermore, these results were also confirmed by histological data. CONCLUSION Results suggest that AP can exhibit therapeutic effects against CP-induced testicular toxicity. It can be concluded that AP may be a potential molecule to abolish reproductive toxicity after chemotherapy.

Abstract
Arbutin (ARB) is a glycosylated hydroquinone with potent antioxidant effects. Although cisplatin (CP) is widely used in chemotherapy, its toxicity in healthy tissues, including ovotoxicity, is an insurmountable problem. This study aimed to evaluate the therapeutic effect of ARB against CP-related ovototoxicity by including nuclear factor erythroid 2-related factor 2 (Nrf2) pathway in rats for the first time. Rats treated one dose of CP (5 mg/kg) on the first day, followed by ARB (5 and 10 mg/kg) for three days. Serum reproductive hormone levels were determined using ELISA kits. Oxidative stress (OS), inflammation, endoplasmic reticulum stress (ERS) and apoptosis markers in ovarian tissue were also determined colorimetrically. In addition, how CP affects Nrf2 pathway and the effect of ARB on this situation were also addressed. ARB treatment reduced the levels of markers of OS, inflammation, ERS and apoptosis in ovarian tissue of CP-stimulated animals. ARB regenerated the depleted antioxidant system by triggering Nrf2 pathway in the ovarian tissues of animals stimulated by CP. Histological findings also supported the therapeutic efficacy of ARB. The results indicate that ARB may have therapeutic effects against CP-induced reproductive toxicity with its Nrf2 activator potential. ARB should be tested in more extensive studies as a new generation chemopreventive candidate molecule.

Abstract
Reproductive toxicity is a serious side effect of cisplatin (CP) chemotherapy. Gentisic acid (GTA) is a phenolic acid with strong antioxidant properties. Here, we aimed to determine therapeutic effect of GTA against CP-induced testicular toxicity in rats for the first time. Male Sprague-Dawley rats received a single dose of CP (5 mg/kg; intraperitoneal) and treated with GTA (1.5 and 3 mg/kg; intraperitoneal; 3 consecutive days). The levels of oxidative stress (OS), inflammation, endoplasmic reticulum stress (ERS) and apoptosis biomarkers were assessed in the testicular tissue of rats. In addition, how CP affects the nuclear factor erythroid-2-related factor 2 (Nrf2) pathway and the effect of GTA on this situation were also addressed in the testicular tissue. CP administration induced histopathological changes in testicular tissue of rats with a significant increase in OS, inflammation, ERS and apoptosis biomarkers and a decrease in antioxidant capacity and Nrf2 expression levels. Administrations of GTA resulted in an amelioration of these altered parameters. These data suggest that GTA may be a potential therapeutic agent against CP-induced testicular toxicity. Activation of the Nrf2 pathway plays a key role of this therapeutic effect of GTA.

Abstract
Although cisplatin (CDDP) is an effective anticancer agent, the ovotoxicity that can occur in female patients limits its use. Oxidative stress (OS) and inflammation are known to contribute to CDDP-induced ovotoxicity. Vanillic acid (VA) is a dietary herbal secondary metabolite with high free radical scavenging activity. It was aimed to evaluate the therapeutic effects of VA against CDDP-induced ovotoxicity in rats in this study for the first time. Ovotoxicity was achieved with a single dose of CDDP (5 mg/kg) in female rats. The therapeutic effect of VA was evaluated with 3-day administration of two different doses (5 and 10 mg/kg). While OS, inflammation, endoplasmic reticulum stress (ERS) and apoptosis markers were measured in tissue samples, the levels of reproductive hormones were determined in serum samples using colorimetric methods. The results showed that CDDP-induced nuclear factor erythroid 2-associated factor 2 (Nrf2) inhibition combined with increased OS, inflammation, ERS and apoptosis increased ovarian damage. VA treatments reversed these changes via activating Nrf2 pathway dose-dependently. In addition, histopathological findings also supported the biochemical results. VA may be a good therapeutic molecule candidate for CDDP-induced ovarian damage due to strong antioxidant and Nrf2 activator properties.

Abstract
5-Fluorouracil (5-FU) is a fluoropyrimidine group antineoplastic drug with antimetabolite properties and ovotoxicity is one of the most important side effects. Silibinin (SLB) is a natural compound that is used worldwide and stands out with its antioxidant and anti-inflammatory properties. The aim of this study was to evaluate the therapeutic effect of SLB in 5-FU-induced ovototoxicity using biochemical and histological analysis. This study was carried out in five main groups containing six rats in each group: control, SLB (5 mg/kg), 5-FU (100 mg/kg), 5-FU + SLB (2.5 mg/kg), and 5-FU + SLB (5 mg/kg). The levels of ovarian malondialdehyde (MDA), total oxidant status (TOS), total antioxidant status (TAS), superoxide dismutase (SOD), catalase (CAT), 8-hydroxy-2'-deoxyguanosine (8-OHdG), tumor necrosis factor-alpha (TNF-α), myeloperoxidase (MPO), and caspase-3 were determined using spectrophotometric methods. Hematoxylin and eosin staining method was employed for histopathological examination. MDA, TOS, 8-OHdG, TNF-α, MPO, and caspase-3 levels in 5-FU group were significantly increased compared with the control group, while the levels of TAS, SOD, and CAT were decreased (p < 0.05). SLB treatments 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 5-FU group compared with the control group, SLB treatments also statistically significantly restored these damages (p < 0.05). In conclusion, SLB has a therapeutic effect on the ovarian damage induced by 5-FU via decreasing the levels of oxidative stress, inflammation, and apoptosis. It may be helpful to consider the usefulness of SLB as an adjuvant therapy to counteract the side effects of chemotherapy.

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
PURPOSE To investigate the possible protective role of syringic acid on torsion/detorsion-induced testicular injury using biochemical and histopathological approaches for the first time. METHODS A total of 24 rats were divided into 4 groups: sham control, torsion/detorsion, torsion/detorsion + syringic acid (50 mg/kg and 100 mg/kg). Tissue malondialdehyde, total oxidant status and total antioxidant status levels were determined using colorimetric methods. Tissue 8-hydroxy-2'-deoxyguanosine, superoxide dismutase, catalase, high mobility group box 1, nuclear factor kappa B protein 65, tumor necrosis factor-alpha, interleukin-6, myeloperoxidase, 78-kDa glucose-regulated protein, activating transcription factor-6, C/EBP homologous protein and caspase-3 levels were determined using commercial enzyme-linked immunosorbent assay kits. Johnsen's testicle scoring system was used for histological evaluation. RESULTS Compared with the control group, the levels of oxidative stress, inflammation, endoplasmic reticulum stress and apoptosis were significantly increased in the torsion/detorsion group (p < 0.05). Syringic acid administrations statistically significantly restored these damage in a dose dependent manner (p < 0.05). Moreover, it was found that the results of histological examinations supported the biochemical results to a statistically significant extent. CONCLUSION The overall results suggest that syringic acid emerges as a potential compound for the treatment of testicular torsion and may be subject to clinical trials.

Abstract
Background
Testicular torsion is an important pediatric problem and ischemia/reperfusion injury (IRI) is involved in its etiopathogenesis. Vanillic acid (VA) is a phenolic acid has strong antioxidant properties. To our knowledge, the ability of VA to reduce testicular IRI has not been previously investigated. It was therefore aimed to evaluate whether VA had a beneficial effect against testicular IRI model in rats for the first time. Twenty-four rats were segregated into four groups: sham control, torsion/detorsion (T/D), T/D + VA (50 mg/kg and 100 mg/kg). The levels of testicular oxidative stress, inflammation, endoplasmic reticulum (ER) stress and apoptosis markers were determined using colorimetric methods. Hematoxylin–eosin staining method was used in the histopathological evaluation.
Results
Oxidative stress, inflammation, ER stress and apoptosis levels were significantly higher in testicular tissues of rats with only IRI model (p < 0.05). VA applications improved these injuries in a dose-dependent manner (p < 0.05). Moreover, it was found that the results of histological examinations supported the biochemical results to a statistically significant extent.
Conclusions
It was revealed that VA application can remove testicular IRI for the first time. This testicular protective efficacy of VA needs to be supported by more extensive preclinical studies.

Abstract
The aim of this study was to investigate the potential therapeutic efficacy of chrysin (CHS) against ovotoxicity caused by intraperitoneal administration of cisplatin (CDDP) in rats. In this experimental study, 24 female rats were randomly divided into four groups: control, CHS (2 mg/kg), CDDP (5 mg/kg) and CDDP (5 mg/kg) + CHS (2 mg/kg). The levels of malondialdehyde (MDA), total oxidant status (TOS), total antioxidant status (TAS), superoxide dismutase (SOD), interleukin-6 (IL-6) and myeloperoxidase (MPO) were determined in the ovarian tissues using spectrophotometric methods. In addition, the ovarian samples were evaluated histopathologically by hematoxylin&eosin staining. The results revealed that the levels of MDA, TOS, IL-6 and MPO significantly increased by CDDP administration compared with control group (p < 0.05). Also, it was found that CDDP significantly decreased TAS and SOD levels (p < 0.05). CHS ameliorated CDDP-induced the increased levels of MDA, TOS, IL-6, MPO and increased the levels of TAS and SOD significantly (p < 0.05). Histological findings also supported the therapeutic effect of CHS against CDDP-induced ovarian damage parameters. In conclusion, our results showed that CHS exhibits a therapeutic effect against CDDP-induced ovotoxicity and therefore the use of CHS after chemotherapy may improve the side effets of CDDP. IMPACT STATEMENTWhat is already known about this subject? Cisplatin (CDDP) is an effective and widely used chemotherapeutic agent to treat various malignancies, but its therapeutic use is limited due to dose-related tissue toxicity. Chrysin (CHS), a natural flavone, exhibits various beneficial activities, including antioxidant, anti-inflammatory and anticancer. There are increasing evidences in the literature that CHS reduces the toxicity of various chemotherapeutic agents, such as CDDP, doxorubicin and cyclophosphamide, in colon, kidney and liver tissues through its antioxidant and anti-inflammatory potential.What do the results of this study add? This study demonstrated that CHS can abolish CDDP-induced in vivo ovarian injury by decreasing MDA, TOS, IL-6 and MPO levels and increasing SOD and TAS levels through its antioxidant and anti-inflammatory potential.What are the implications of these findings for clinical practice and/or further research? This study revealed the therapeutic potential of CHS against CDDP-induced acute ovotoxicity, for the first time. Further pre-clinical studies are necessary to prove the beneficial effect of CHS on the prevention of CDDP-induced ovarian toxicity.

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.

Abstract
Although several studies have investigated the cytotoxic effects of different Fabaceae species, limited researches have been conducted on the cytotoxic effect of Dorycnium pentaphyllum. The aim of this study was to evaluate the phenolic characterization and the cytotoxic effect of D. pentaphyllum on human cervix (HeLa) and colon (WiDr) cancer cells and the possible mechanisms involved. Total phenolic content (TPC) and phenolic characterization of the extract were investigated using the Folin-Cioceltau method and RP-HPLC, respectively. The cytotoxic effect of the extract was evaluated using the MTT assay. The mechanism involved in the extract's cytotoxic effect was then evaluated in terms of apoptosis and the cell cycle using flow cytometry, while mitochondrial membrane potential (MMP) was investigated using the fluorometric method. The TPC value of the extract was 141.2 ± 0.8 mg gallic acid equivalent per g sample, and quercetin was detected as major phenolics. D. pentaphyllum extract exhibited a selective cytotoxic effect on HeLa and WiDr cells compared to normal fibroblast and colon cells, respectively. The extract induced cell cycle arrest at the S phase and apoptosis via reduced MMP in these cells. Further studies may be useful in developing a natural product based new generation pharmacological agent.

Abstract
OBJECTIVES Intestinal motility is regulated by several neurotransmitters and neuropeptides including dopamine and acetylcholine as well as ghrelin. Metoclopramide and domperidone are long-standing treatment options for dysmotility, and erythromycin is suggested in selected patients. In the present study, we aimed to investigate the effects of mentioned prokinetics on ghrelin levels. METHODS Serum ghrelin levels were estimated by using enzyme-linked immunoassay following a single administration of domperidone, metoclopramide, or erythromycin. RESULTS Our results showed that both antidopaminergic and cholinergic prokinetics increase the circulating ghrelin levels. There was no significant difference between enteral and parenteral control groups. Also, statistical analysis revealed that neither prokinetic was superior to the other in regard to its ghrelin stimulating effect. CONCLUSION Conclusively, the present study demonstrated that the circulating levels of ghrelin increase by the administration of antidopaminergic and cholinergic prokinetics. Hence, this effect on ghrelin may partly be responsible for the motility‑stimulating actions of domperidone, metoclopramide, and erythromycin (Fig. 2, Ref. 39).

Abstract
OBJECTIVES Cisplatin (cis-diamminedichloroplatinum (II)) is a widely-used platinum-based chemotherapeutic agent which has dose-limiting side-effects. Also, the drug resistance is another instance that decreases treatment success in cisplatin chemotherapy. The growing body of evidence suggests that curcumin, a polyphenolic compound extracted from the spice turmeric, may exert synergistic effects and sensitize malign cells to cisplatin, while alleviating cytotoxicity-related side-effects. The present study was aimed to investigate mood-associated interactions between cisplatin and curcumin. MATERIALS AND METHODS Thirty-four adult male Wistar albino rats were randomly assigned to four groups as control, curcumin (300 mg/kg/day, p.o. for 5 weeks), cisplatin (5 mg/kg/week, i.p. for 5 weeks), and curcumin plus cisplatin (same doses as above). The open field, elevated plus maze, and forced swim tests were engaged to evaluate mood-associated behaviors. RESULTS We demonstrated that depression- and anxiety-like behaviors were not altered by the administration of curcumin along with the chronic cisplatin treatment. CONCLUSION According to the results of the present study, we concluded that curcumin might be regarded as a safe adjuvant in cisplatin chemotherapy in terms of the mood-associated behaviors (Fig. 4, Ref. 41).
