Zusammenfassung:Stroke, especially hemorrhagic form, is one of the most serious comorbidity disease of diabetes mellitus, often associated with high mortality, particularly in type 2 DM (T2DM). Therefore, it is relevant the search for drugs with a metabolically justified protective effect. Edaravone (Eda) is widely used for treating ischemic stroke but its biochemical effects in intracerebral hemorrhage (ICH) associated with T2DM is not still confirmed. The aim of the study was to assess the impact of Eda on the markers of oxidative modification of proteins (OMP), such as advanced oxidation protein products (AOPP), neutral and basic carbonyls (PC370 and PC430), advanced glycation end products (AGE) and ischemia modified albumin (IMA) as well as on the activity of matrix metalloproteinases MMP2/MMP9 (gelatinases) in rats with experimental T2DM after collagenase-induced ICH. Metformin was used as a comparative drug. The data obtained indicate that ICH in diabetic rats is accompanied by an increase in AOPP, PC370, AGE, and mature forms of both gelatinases. On the contrary, IMA and proMMP9 were below normal level after ICH. Both studied drugs decreased the OMP markers to the levels of intact rats or lower, and Eda show a more potent effect. Besides, Eda significantly decreased the activity of MMP9 and changed progelatinases activity. We conclude that Eda has a perspective to be useful in the treatment of comorbid brain hemorrhage in T2DM due to inhibiting of oxidative stress and modulation of gelatinases activity.
