Background: The activation of Nrf2/HO-1 pathway has been shown to protect against cisplatin- induced nephrotoxicity by reducing oxidative stress. Berberine (Ber), an isoquinoline alkaloid, has demonstrated antioxidant, anti-inflammatory and anti-apoptotic activities in various experimental models. Aim: To check the effect of Ber on cisplatin-induced nephrotoxicity and to explore the involved mechanism. Methods: Adult male Wistar rats were divided into 6 groups: Normal, cisplatin-control, treatment groups and per se group. Normal saline and Ber (20, 40 and 80 mg/kg; p.o.) was administered to rats for 10 days. A single intraperitoneal injection of cisplatin (8 mg/kg) was injected on 7th day to induced nephrotoxicity. On 10th day, rats were sacrificed, the kidney was removed and stored for the estimation of various parameters. Results: As compared to cisplatin-control group, Ber pretreatment improved renal function system and preserved renal architecture. It also diminished oxidative stress by upregulating the expression of Nrf2/HO-1 proteins. In addition, Ber attenuated the cisplatin mediated inflammation and apoptosis. Furthermore, it also reduced the phosphorylation of p38/JNK and PARP/Beclin-1 expression in the kidney. Conclusion: Ber attenuated renal injury by activating Nrf2/HO-1 and inhibiting JNK/p38MAPKs/ PARP/Beclin-1 expression which prevented oxidative stress, inflammation, apoptosis and autophagy in renal tissue.

Oxidative stress is an imbalance between free radicals and antioxidants, and is an important etiological factor in the development of hypertension. Recent experimental evidence suggests that subpressor doses of angiotensin II elevate oxidative stress and blood pressure. We aimed to investigate the oxidative stress related mechanism by which a subpressor dose of angiotensin II induces hypertension in a normotensive rat model. Normotensive male Wistar rats were infused with a subpressor dose of angiotensin II for 28 days. The control group was sham operated and infused with saline only. Plasma angiotensin II and H2O2 levels, whole-blood glutathione peroxidase, and AT-1a, Cu/Zn SOD, and p22phox mRNA expression in the aorta was assessed. Systolic and diastolic blood pressures were elevated in the experimental group. There was no change in angiotensin II levels, but a significant increase in AT-1a mRNA expression was found in the experimental group. mRNA expression of p22phox was increased significantly and Cu/Zn SOD decreased significantly in the experimental group. There was no significant change to the H2O2 and GPx levels. Angiotensin II manipulates the free radical-antioxidant balance in the vasculature by selectively increasing O2− production and decreasing SOD activity and causes an oxidative stress induced elevation in blood pressure in the Wistar rat.

Abstract: Overtraining accelerates aging due to the excessive production of free radicals that can cause oxidative stress. Banana floret extract contains bioactive compounds with antioxidant capacity which can increase the body's defence to deal with the oxidative stress by increasing the level of superoxide dismutase (SOD). This study was aimed to prove that the banana (Musa x paradisiaca) floret extract could prevent the decrease of superoxide dismutase (SOD) levels in overtraining-induced mice (Mus musculus) BALB/c liver. This was a true experimental study with the post-test only control group design. Subjects were 36 male mice (Mus musculus), BALB/c strain, 12 weeks old, weighing 20-22 g, which were divided into two groups with 18 mice each. The control group (P0) was treated with a placebo of 1 ml aquadest and overtrained for 14 days meanwhile the treatment group (P1) was treated with banana (Musa x paradisiaca) floret extract of 400 mg/kgBW/day and overtrained for 14 days. The results showed that after 14-day treatment, the mean SOD level in the liver tissue of the P0 group was 568.82±9.558 U/mg protein whereas in the P1 group was 588.37±10.629 U/mg protein (P < 0.01). The t-independent test showed a t value of -5.804 and a P value of 0.000 which indicated that after treatment, the levels of SOD in liver tissue of both groups were significantly different. Conclusion: Banana (Musa x paradisiaca) floret extract could prevent the decrease of superoxide dismutase (SOD) levels in the liver tissue of overtraining-induced mice (Mus musculus) BALB/c.Keywords: banana floret, SOD, liver, overtrainingAbstrak: Aktivitas fisik berlebih mempercepat penuaan karena meningkatkan produksi radikal bebas yang dapat menyebabkan stres oksidatif.
