Abstract

BACKGROUND: Ischemia-reperfusion injury is one of the leading causes of acute renal failure which is a common clinical event leading to development of chronic kidney disease and a high mortality; especially in elderly people. β-glucans are glucose polymer groups with free-radical scavenger, macrophage activator, and immune defense inducer functions. We designed this study to determine the possible protective effects of β-glucan against renal ischemia-reperfusion injury comparatively in young and aged rats. METHODS: Rats were assigned to the following groups: Young and aged sham, young and aged ischemia-reperfusion, young and aged β-glucan, young and aged ischemia-reperfusion+β-glucan. At the end of the experiment, following collection of blood samples, rats were sacrificed and kidneys were removed for histopathological and biochemical examination. RESULTS: Mean tissue histopathological damage scores of young β-glucan group was lower than that of young ischemia-reperfusion group, and of aged β-glucan group was lower than that of aged ischemia-reperfusion group. Urea and creatinine levels of young and aged of sham group and β-glucan administered groups were all lower than those of ischemia-reperfusion and β-glucan+ischemia-reperfusion groups. Oxidative stress indexes of ischemia-reperfusion groups were increased however ; oxidative stress indexes of β-glucan administered to young and aged rats were lower than those of ischemia-reperfusion groups. CONCLUSIONS: We conclude that β-glucan is effective to protect kidneys from ischemia-reperfusion-induced oxidative damage, especially in young rats.
