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
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
PURPOSE Cyclophosphamide (CYP) is an antitumor drug. However, in addition to its antitumor affect, CYP can also lead to nephrotoxicity and hemorrhagic cystitis. The purpose of this study was to investigate the potential protective effects of Pterostilbene (Pte), a natural antioxidant as a resveratrol analog against CYP-induced nephrotoxicity and cystitis in rats. METHODS Twenty-one male Sprague Dawley rats were divided into 3 equal groups. The control group and the CYP group (CYPG) received 1 ml/kg sunflower oil per day, and the CYP + Pte group (CYP + PteG) 40 mg/kg per day Pte dissolved in sunflower oil once a day via the oral route for 14 days. In addition, on day 9 of the experiment, CYPG and CYP + PteG received a single dose of 200 mg/kg CYP dissolved in saline solution, while the control group received a single dose of 10 ml/kg saline solution, via the intraperitoneal route. Bladder and kidney tissues were collected for histological and biochemical evaluations. RESULTS Pte was observed to reduce CYP-derived increases in malondialdehyde level, total oxidant status (TOS), the oxidative stress index (OSI), and apoptosis in kidney tissues and to cause an increase in superoxide dismutase levels. It also reduced CYP-derived increases in TOS, OSI, and apoptosis in bladder tissue. Moreover, Pte also ameliorated histopathological findings associated with CYP-induced tissue damage in both the kidney and bladder. CONCLUSION Our study findings show that Pte may exhibit a protective effect against CYP-induced nephrotoxicity and cystitis.

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.
