title: Comparative study on the effect of energy drinks on haematopoietic system in Wistar albino rats.
abstract: Energy drinks have become popularized and the market value for these drinks is continually growing. Therefore, the present study aimed to evaluate the effect of three popular kinds of energy drinks (Power Horse, Red Bull and Code Red) on certain hematological parameters and on the ultrastructure of blood cells in male Wistar albino rats. Animals were treated orally with Power Horse, Red Bull and Code Red respectively for 4 weeks. Blood samples were taken after two and four weeks for determination of haematological indices. Ultrastructure examination of blood cells was carried only after 4 weeks of treatment. The results indicated significant reduction (P < 0.05) in red blood cell count, haemoglobin content, haematocrit value, blood platelets count and neutrophils in animals treated with Red Bull and Power Horse and these changes were time dependant. Insignificant changes were recorded in rats administered with Code Red. On the other hand, ultrastructural alterations, including both nucleus and cytoplasm of peripheral blood cells, were recorded in all treated animals but they were more pronounced in animals received Red Bull and Power Horse. It is concluded that energy drinks have serious detrimental impacts on haematopoietic system of male rats.
