Evaluation of the physiological and histological effects induced by some energy drinks on male rabbits

Energy drinks are widely available and popular. This raised concerns about their effects on human health. The present
study aimed to evaluate the physiological and histological effects induced by the following energy drinks: Power Horse,
Bison and Code Red, on male rabbits. Twenty male rabbits were divided into four groups (5 rabbits each). Group 1 was
served as control group, while groups 2, 3, and 4 were daily ingested with only one type of energy drinks for 5 weeks.
Rabbits were weighed before and during the experiment. After five weeks, samples were taken from animals of each
group as follows: Whole blood and biopsy from liver were collected for biochemical and histopathological examinations.
The current study showed that treatment with energy drinks increased both body weight and liver enzymes (AST, ALT and
ALP) when compared to control. Power horse drink was the most effective on liver enzymes, followed by bison and code
red drinks. Additionally, histological changes were observed in the hepatic tissues of treated rabbits when compared to
control. These changes depend on elevated liver function enzymes. In conclusion, the consumption of energy drinks
affects physiologically and histological the liver of rabbits
