Silymarin (SL), a flavonolignan complex isolated from seeds of Silybum marianum (Asteraceae), is known for its hepatoprotective, anti-apoptotic, anti-inflammatory, and antioxidant activities. A glycopeptide antibiotic, Vancomycin (VA) which is used for the treatment of serious infections caused by multi-resistant Gram-positive microorganisms has been clinically used for a long time. The aim of the present study was to evaluate potential therapeutic efficiency of SL against VA-induced apoptosis and inflammation using apoptotic (caspase-3, -8, and, -9) enzyme activities) and inflammatory (Tumor necrosis factor-alpha (TNF-α)) markers, and histopathological examinations in rat liver. A total of 49 male Wistar albino rats was divided into 7 groups including control (saline, intraperitoneally (i...

Silymarin (SLY), a flavonoid complex isolated from the seeds of Silybum marianum (Asteraceae), has antioxidant, anti-apoptotic, anti-inflammatory, and anti-lipid peroxidative effects. Vancomycin (VA), used for treating serious infections, has been associated with nephrotoxicity, which limits its use. Therefore, this study aimed to investigate the potential renoprotective effects of SLY on VA-induced nephrotoxicity using renal, apoptotic (caspase-3, caspase-8, and caspase-9 enzyme activities), and oxidative stress [nitric oxide (NO) and malondialdehyde (MDA)] markers; serum blood urea nitrogen (BUN) and creatinine levels; and histopathological examination. A total of 49 male Wistar albino rats were used (n = 7): control [saline, intraperitoneally (i.p.)], dimethyl sulfoxide (i.p.), VA [400 ...

Purpose: This study investigated the antiinflammatory efficacy of topical application of a selective tyrosine kinase receptor inhibitor (TKI), Axitinib in experimental corneal neovascularization (CNV) model in rats. Vascular endothelial growth factor receptor 1 (VEGFR1), VEGFR2 and VEGFR3 were evaluated as angiogenic markers, nuclear factor kappa B (NF-κB), tumor necrosis factor α (TNFα) and cyclooxygenase-2 (COX2) were determined as inflammatory markers and also histopathological evaluations were carried out. Materials and Methods: Experimental CNV model was established by silver nitrate cauterization in right eye. 6 groups were included as Control; CNV; CNV+DMSO; CNV+0.04% Axitinib; CNV+0.08% Axitinib and CNV+0.24% Axitinib. The corneas were collected and VEGFR1, VEGFR2, VEGFR3, NF-κB...
