Changes in shape and size of erythrocytes can contribute to their elimination by phagocytes from circulation, and subsequently, can lead to anemia development (Stasiuc et al., 2009). Satureja montana L. (Lamiaceae), is an aromatic species with proved very strong pharmacological activities and antioxidative properties due to the presence of phenolic compounds. The present study investigated possible influence of the Satureja montana L. leaves methanol extract on the rat erythrocytes membrane. Objectives: The aim of this study was to determine the effect of the various concetrations of the Satureja montana L. leaves methanol extracts on the rat erythrocytes morphology ex vivo. Materials and Methods: The red blood cells (RBC) of male rats of Wistar strain were ex vivo treated with S. montana leaves methanol extract. We used following concentration: 100µg/ml (I), 150µg/ml (II) and 300µg/ml (III) and incubated with RBC at 37°C for 1h (Bors et al., 2012). The erythrocytes incubated with phosphate buffered saline – PBS (P) and PBS + dimethyl sulfoxide – DMSO (D), (PD) were used as controls. The percentage of erythrocytes with different shape morphology (e.g. echinocytes, stomatocytes) were calculate. Results: In contrast to the biconcave disc shape of control red blood cells, the RBC incubated with the different concentration of methanol extracts underwent shape changes typical for echinocyte and stomatocyte formation. We found that within creasing concentration of methanol leaves extracts (I100µg/ml, II-150 µg/ml and III-300 µg/ml), gradually raised the percentage of different erythrocytes shape forms in comparison to both controls. The most significant changes were observed at concentration of 300µg/ml, with the highest percentage of echinocytes and stomatocytes forms. It is possible that phenolic compounds, predominantly present in S. montana leaves methanol extracts, could interacted with or incorporated into either erythrocyte membrane outer monolayer promoting echinocytosis or erythrocyte membrane inner monolayer prompting stomatocytosis. Conclusion: The methanol extract of S. montana leaves in dose-dependent manner stimulates phospholipid scrambling of the rat erythrocyte cell membrane, an effect probably in part dependent on entry of secondary constituents. Its beneficial effect via protecting the cell membrane against oxidation in vivo could be suggested. |
