“…Moreover, renal I/R resulted in a significant increase in FE Na+ on the 2 time points of follow-up after ischaemia, suggesting a significant impairment of tubular function. These findings confirm that I/R injury to the kidney causes both glomerular and tubular dysfunctions, and are in agreement with those reported by others (Bussmann et al, 2014;Castro et al, 2014;Malek and Nematbakhsh, 2015;Punuru et al, 2014). Renal I/R injury is characterized by decreases in the glomerular filtration rate (GFR), tubular and glomerular damage, impairment in hemodynamic regulation and energy depletion (Malek and Nematbakhsh, 2015).…”

Background. The present work was designed to study the effects of methanolic stevia extracts and aerobic exercise and combination of both on renal I/R injury in male rats. Methods. 60 adult male Sprague-Dawley rats were subdivided into five equal groups as sham, control, exercise, stevia, and stevia plus exercise group. After 5 weeks of exercise and stevia, animals were exposed to 45 min of left renal ischemia and right nephrectomy followed by reperfusion. Serum creatinine, creatinine clearance, fractional Na excretion (FE Na +), malondialdehyde (MDA), reduced glutathione (GSH) and catalase (CAT) levels in kidney tissues were measured. Also, renal histopathology and the expression of caspase-3 by immunohistochemical examination were done. Results. The results showed that stevia, exercise or combination of stevia and exercise caused a significant decrease in serum level of creatinine (p < 0.001) and FE Na + (p < 0.001) and an increase in creatinine clearance (p < 0.001). Moreover, this caused a significant decrease in (MDA; p < 0.046) and an increase in GSH (p < 0.01) and CAT (p < 0.01), as well as causing a significant decrease in caspase 3 expression compared to the control group. Conclusion. Pretreatment with either stevia or exercise of combination of both seem to have protective effects on renal I/R injury. However, the protective effect of exercise against renal I/R injury seems to be less than stevia. These effects might be due to attenuation of oxidative stress and apoptosis in kidney tissues.

“…Allopurinol, an isomer of hypoxanthine, is an inhibitor of XO. Therefore, it may inhibit I/R injury by this mechanism 21 . In our present study, allopurinol preconditioning also restored renal function caused by 30 min IRI (Figure 1).…”

PURPOSE:To investigate the potential effects of pretreatment with allopurinol on renal ischemia/reperfusion injury (IRI) in a rat model. METHODS:Twenty four rats were subjected to right kidney uninephrectomy were randomly distributed into the following three groups (n=8): Group A (sham-operated group); Group B (ischemic group) with 30 min of renal ischemia after surgery; and Group C (allopurinol + ischemia group) pretreated with allopurinol at 50 mg/kg for 14 days. At 72 h after renal reperfusion, the kidney was harvested to assess inflammation and apoptosis. RESULTS:Pretreatment with allopurinol significantly improved renal functional and histological grade scores following I/R injury (p<0.05). Compared with Group B, the expression levels of caspase-3 and Bax were markedly reduced in Group C, meanwhile, whereas expression of bcl-2 was clearly increased (p<0.05). A newly described marker of inflammation, High Mobility Group Box 1(HMGB1), showed reduced expression in Group C (p<0.05). CONCLUSION:Pretreatment with allopurinol had a protective effect on kidney ischemia/reperfusion injury, which might be related to the inhibition of HMGB1 expression.Key words: Inflammation. Ischemia.

“…Bussmann et al 7 report that the duration of ischemia directly influences the levels of plasma creatinine and degree of renal injury: plasma creatinine levels increased twice after 25 minutes of ischemia and seven to eight times after 45 minutes, which is associated with significant necrosis. This information was important in this study to induce ischemia for a shorter period, ten minutes, in order to minimize injuries.…”

PURPOSE:To investigate biomarkers of acute renal injury in Wistar rats, subjected to left renal ischemia for 10 minutes, and then compare reperfusion at 24 hours, and at 5, 7, 14 and 21 days after the procedure. METHODS:Eight female and male rats between 60 and 81 days old were used in the Central Animal Facility of the UFMS. Assessed biomarkers included urine protein, urea, creatinine, glucose, sodium, potassium, urine alkaline phosphatase and gamma-glutamyl transferase activities, and protein-to-creatinine ratio; and in serum: urea, creatinine, sodium and potassium, fractional excretion of sodium, potassium, urine flow and creatinine clearance. RESULTS:Greater variance was observed in the parameters at 24 hours and at five days (p<0.05) after reperfusion. On the 21 st day, these parameters approximated those obtained for the control group. CONCLUSIONS:Renal ischemia for 10 minutes was sufficient to raise urine levels of protein, glucose, fractional excretion of potassium, urea, creatinine clearance, urine activity of gamma-glutamyltransferase and alkaline phosphatase enzymes in the first 24 hours, up to five days after reperfusion, which may indicate risk of acute kidney injury, according to the RIFLE classification.
