13 In the present study 5-FU treated rats demonstrate augmented level of MDA, lipid find more peroxidation marker compared to control rats as reported by Ali.5 The ingestion of BP to 5-FU treated rats considerably decreased MDA compared to group II. Since the most essential pharmacologically active components in BP are flavonoids and various phenolics which

have free radical scavenging power and thus protecting lipids from being oxidized during oxidative damage.14 SOD forms the primary shield against superoxide as it converts reactive superoxide radicals to H2O2 and H2O. However, Glutathione peroxidase (GPx) converts H2O2 and other ROS to H2O2 and H2O. Catalase (CAT) catalyzes H2O2 to H2O and O2. In the present study, the activities of SOD,

GPx, GR and CAT were significantly decreased in group II as compared to I. BP administration to 5-FU treated groups improved these enzymes, may be by scavenging singlet oxygen, superoxide anions, peroxy radicals, OH-. GSH is a tripeptide which detoxifies ROS efficiently, gets depleted after 5-FU injection and gets replenished by BP prophylaxis. Present work supports Bhadauria.15 BUN, creatinine and LDH levels were augmented in 5-FU group.5 In contrast, BP ameliorated their levels as compared to group II. This is an indicator of the possible nephroprotective efficacy offered by BP against 5-FU toxicity indicating that BP has a tendency to thwart damage and inhibit the seepage of enzymes through cellular membranes. KIM-1 is a transmembrane tubular protein Alectinib PAK6 and is barely discernible in normal kidneys, nevertheless, it is

strikingly induced in acute kidney injury and chronic kidney disease. It is a sensitive and explicit marker of kidney injury as well as predictor of prognosis as supported by Huo.16 In our study, KIM-1 levels were markedly increased in group II. Although, prophylactic treatment of BP suppressed abnormal levels of KIM-1. TNF-α is a proinflammatory cytokine which plays a widespread role in many biological processes like cell death, growth, development, oncogenesis and immune responses. Present study also illustrated that 5-FU administration significantly increases TNF-α. It has been reported that oxidative stress may also commence or augment inflammation via upregulation of various genes implicated in the inflammatory mechanisms. NFkB is one of them, whose activation results in the upregulation of proinflammatory cytokines. Oxygen free radicals and TNF-α could activate NFkB which is a redox sensitive transcription factor, which in turn stimulates the successive inflammatory cascade. However mechanistic pathway of NFkB signaling and its correlation with oxidative stress is not fully clear.
