Using a wide range of different physical and chemical methods, it was found that the oxidative stress caused by addition of hydrogen peroxide to the incubation medium has a significant effect on the conformation of haematoporphyrin, influencing the oxygen-binding properties of haemoglobin in red blood cells. Morphofunctional characteristics of red blood cells change; in particular, we have observed the transformation of erythrocytes, their transition into echinocytes. In erythrocytes, in response to increased lipid peroxidation (LPO) antioxidant enzymes become active. The use of natural antioxidants (β-carotene and resveratrol) works towards reducting the level of oxidative processes. Resveratrol has the greatest antioxidant effect.

Abstract It is known fact that diabetes mellitus (DM) affects blood cells. Changes in the erythrocyte membrane, disorder in hemoglobin oxygen-binding and modification in mechanical characteristics, are effects of hyperglycemia on red blood cells. Altered susceptibility infection of patients with diabetes has been ascribed to a depression in the function of polymorphonuclear leukocytes. Neutrophil function in patients with diabetes with good glucose control is slightly different than in healthy ones. DM causes significant changes in lymphocytes metabolism and their functions. Patients with diabetes, presenting with acute coronary syndrome, are at higher risk of cardiovascular complications and recurrent ischemic events in comparison to non-diabetic counterparts. Various mechanisms, including endothelial dysfunction, platelet hyperactivity, and abnormalities in coagulation and fibrynolysis have been implicated for this increased atherothrombotic risk. There are many other alterations of blood cells due to DM. In the present review we focused on modifications of blood cells due to DM. Then, as a second point, we explored how the changes affect functions of red blood cells, white blood cells and platelets.

AbstractResveratrol, an important phytoalexine found in many plants, has been shown to be significantly effective in the treatment of several pathological conditions such as cancer, coronary heart disease and osteoarthritis. This study focuses on the effects of this drug on human red blood cells. In particular, we have examined the influence of resveratrol on Band 3, the anion exchanger protein, and hemoglobin as a function of the oxygenation-deoxygenation cycle. Moreover, special attention has been given to the metabolic changes imposed by caspase 3 activation. Resveratrol has proved to lower superoxide production, thereby decreasing heme-iron oxidation and saving the reducing power required for met-hemoglobin reduction. Oxygen binding experiments showed that resveratrol interacts with hemoglobin, shifting the T→R conformational transition towards the higher-affinity R state. This might contribute to altering the metabolic balance of the cell through an intensification of the pentose phosphate pathway. Moreover, at high oxygenation levels of the erythrocytic hemoglobin, resveratrol induces a significant activation of caspase 3, the action of which on Band 3 has a strong impact on cellular metabolism and anion transport.
