ABSTRACT

Excessive glucose concentrations in blood and cells promote the intensification of auto-oxidation. This is one of the mechanisms through which free radicals form in hyperglycemia. As a result of hyperglycemia, oxidative stress develops and lipid peroxidation (LPO) is enhanced. Erythrocytes are particularly susceptible to reactive oxygen species and LPO, which can violate cell functions. This article describes the analysis of the influence of mycelia from the medicinal mushrooms Agaricus brasiliensis and Ganoderma lucidum on the enzymatic link of the antioxidant system in rat erythrocytes under streptozotocin-induced diabetes mellitus. Oxidative stress was strengthened in red blood cells of diabetic rats, as evidenced by decreased activity of antioxidant enzymes such as superoxide dismutase, catalase, glutathione peroxidase, and glutathione reductase, and by increased amounts of thiobarbituric acid–positive products, which are markers of LPO. Administration of A. brasiliensis and G. lucidum submerged cultivated mycelial powder to animals with streptozotocin-induced diabetes restored superoxide dismutase, catalase, and glutathione peroxidase activity and reduced the amounts of thiobarbituric acid–positive products to control values, but did not affect the activity of glutathione reductase.
