    This study investigated the possible protective and therapeutic effects of Myrtus communis subsp. communis ethanol extract (MC) in aluminum chloride (AlCl3) and D-galactose (D-Gal) induced Alzheimer's disease in rats. MC was orally given to rats as a protective treatment for 90 days and, in other two groups starting from the 60th day MC (100-200 mg/kg) was administered, concomitantly with AlCl3 and D-Gal. Learning and memory functions were evaluated by the behavioral tests. Biological activities of MC treatment were examined in hippocampal tissues by ELISA tests. D-Gal and AlCl3-treated rats showed increased amyloid beta (A ss) and 8-hydroxy-2-deoxyguanosine (8OHdG) levels, acetylcholinesterase activity and decreased neprilysin, Na+-K+ATPase and SOD levels in parallel with a decrease in Novel Object Recognition Test, Morris Water Maze and Passive Avoidance Test scores. On the other hand, MC administration reversed the behavioral impairments and improved learning and memory. Moreover, MC treatment decreased A ss and 8-OHdG levels and acetylcholinesterase activity and increased neprilysin levels, Na+-K+ATPase and SOD levels. Our results suggest that MC has beneficial effects on cognitive and neuronal functions through its anticholinesterase and antioxidant properties.

    The Effect of <i>cotinus Coggygria</I> L. Ethanol Extract in the Treatment of Burn Wounds

    The overall aim of the present research is to evaluate for the first time the curative effect of Cotinus coggygria leaves on burn injury in an experimental burn model along with its anti-inflammatory and antioxidant activity potential. Also, phenolic compounds of C. coggygria were characterised by LC-MS/MS. Wistar albino rats weighing 200-250 g were exposed to 90 degrees C bath for 10 s to induce burn injury, involving 30% of the total body surface area. In the treatment groups, 5% C. coggygria ethanol extract was applied topically as a cream immediately after the burn. Blood and skin tissue samples were taken after decapitation at the 4th and 48th hours following the burn procedure. Interleukin 1-beta (IL-1 beta) and tumour necrosis factor (TNF-alpha) were determined in serum samples, and hydroxyproline, prostoglandin E2 (PGE2), and myeloperoxidase (MPO) activity and 8-hydroxy-2'-deoxy-guanosine (8-OHdG) levels were determined in skin tissue samples. Increased levels of serum cytokines were decreased with C. coggygria treatment in both periods. MPO activity, prostaglandine (PGE2), and 8-OhdG levels increased, while hydroxyproline levels decreased due to burn damage. On the other hand, these parameters were returned to its normal levels with C. coggygria treatment. In addition, the tissue histology of animals treated with C. coggygria showed a complete epithelialization with increased collagenation. As a result, C. coggygria may be an alternative treatment approach for burns-induced skin damage and wounds.
