Paclitaxel (PTX), which is actively used in the treatment of many types of cancer, has a toxic effect by causing increased oxidative stress in testicular tissues. Naringin (NRG) is a natural flavonoid found in plants, and its antioxidant properties are at the forefront. This study aims to investigate the protective feature of NRG in PTX‐induced testicular toxicity.Thirty‐five male Sprague rats were divided into five groups: control, NRG, PTX, PTX + NRG50, and PTX + NRG100. Rats were administered PTX (2 mg/kg, BW) intraperitoneally once daily for the first 5 days. Then, between the 6th and 14th days, NRG (50 and 100 mg/kg) was administered orally once a day.NRG reduced PTX‐induced lipid peroxidation and increased testicular tissue antioxidant capacity (superoxide dismutase, catalase, glutathione peroxidase, and glutathione). While NRG reduces the mRNA expression levels of nuclear factor kappa B, tumor necrosis factor‐alpha, interleukin‐1 beta, cyclooxygenase‐2, interleukin‐6, inducible‐nitric oxide synthase, mitogen‐activated protein kinase 14 (MAPK)14, MAPK15, c‐Jun N‐terminal kinase, P53, Apaf1, Caspase3, Caspase6, Caspase9, and Bax in testicular tissues; it caused an increase in Nrf2, HO‐1, NQO1 and Bcl‐2 levels. NRG also improved the structural and functional integrity of testicular tissue disrupted by PTX. PTX‐induced sperm damage was alleviated by NRG.NRG showed a protective effect by alleviating the PTX‐induced testicular toxicity by increasing oxidative stress, inflammation, apoptosis, and autophagy.

Aspirin is one of the most widely used non-steroidal anti-inflammatory drugs worldwide. Neurodegenerative diseases adversely affect the central nervous system, leading to cognitive decline. Aspirin has different pharmacological activities at different doses. Therefore, this study aimed to determine the effects of acetylsalicylic acid (ASA), the active ingredient of aspirin, administered at different doses on the parameters that play a role in cognitive function using molecular and histological methods and behavioral tests. For this purpose, 28 Wistar rats were divided into 4 groups. Control, ASA-low dose (1mg/kg), ASA-moderate dose (10mg/kg) and ASA-high dose (100mg/kg). ASA was intragastrically administered as a single dose, and an open field test was performed 3 hours later. Subsequently, hippocampus tissues were obtained, and the hippocampus tissue structure was analyzed by analyzing the parameters involved in antioxidant capacity, inflammation, apoptosis, and memory. ASA, especially at moderate doses, increased antioxidant capacity and partially reduced inflammation and apoptotic damage. At high doses, the opposite effect was observed, and the damage levels. Similar effects were detected by histological examination. Although there were no structural defects at low or moderate doses, structural defects were observed at high doses. Although there was no difference in the open field test findings between the groups, the time spent in the center, distance traveled, and speed was slightly higher in the ASA moderate-dose group. In conclusion, ASA may contribute to the improvement of cognitive function at low and moderate doses. However, high doses may cause cognitive impairment.

Cisplatin is one of the most active cytotoxic agents used mainly in the treatment of solid tumors. High doses and long-term use of Cisplatin are known to cause cardiotoxicity. In recent years, the antiapoptotic and antioxidant effects of Carvacrol in cardiovascular diseases have attracted attention. In this study, the effects of Carvacrol on Cisplatin-induced cardiotoxicity in a rat model were investigated using biochemical and histological methods. Twenty-eight rats were divided into 4 groups: 1. Control group, 2. Carvacrol group, 3. Cisplatin group, 4. Cisplatin + Carvacrol group. The expression of antioxidant enzymes, proinflammatory cytokines, apoptotic, and autophagic proteins was examined in heart tissue obtained from rats sacrificed after the last drug administration. Additionally, heart tissue was evaluated histopathologically. Cisplatin has been observed to cause oxidative stress and inflammatory damage in animal heart tissue. Carvacrol administration significantly increased antioxidant enzyme (superoxide dismutase and glutathione peroxidase) activities while suppressing inflammatory markers (NF-κB, TNF-α, IL-1β). Additionally, Cisplatin induced apoptotic (caspase-3, Bax, Bcl-2) and autophagic (Beclin-1, LC3A, LC3B) markers. It has been determined that carvacrol can protect heart tissues from the destructive effects of cisplatin by exerting anti-apoptotic and anti-autophagic effects. The expression levels of Notch1 and Hes1, which were decreased by cisplatin administration, were upregulated after administration of Carvacrol. H&E staining results showed that Carvacrol preserved myocardial tissue integrity. In conclusion, Carvacrol showed a cardioprotective effect against cisplatin-induced cardiotoxicity.
