The study of hemoglobin forms under the conditions of energy drink consumption
Abstract
In today’s world, where stress and busyness are an integral part of everyday life, energy drinks have become not only a means of satisfying the need for energy and maintenance of vitality, but also a symbol of lifestyle, an important element of the modern culture of consumption. The speed and efficiency they promise attract the attention of consumers, especially those who are constantly on the move. Such drinks have become popular not only among young people, but also among everyone who seek to maintain their activity and efficiency during the day. The purpose of the work was to investigate the dynamics of changes in the level of total hemoglobin and its forms, in particular oxy-, carboxy-, sulf-, met-, and dyshemoglobin under the conditions of energy drink consumption. The study was conducted using male Wistar rats weighing 150–220 g kept in the vivarium under appropriate lighting conditions, temperature, humidity and standard diet. All the animals had free access to feed (based on daily requirements) and water (based on 20 ml of water per rat per day). The experiment was carried out in compliance with the requirements of the European Convention for the Protection of Vertebrate Animals used for Experimental and Scientific Purposes (Strasbourg, 1986). The animals were divided into five groups: the 1st group received drinking water (intact control); the 2nd–5th groups received daily the non-alcoholic energy drink “Burn” per os for a month. The calculation of the required amount of drink for administration per one rat was based per 1 kg of body weight. To monitor the growth and development, we weighted the rats at the beginning and at each stage of the experiment. The material (blood) was taken on the 1st (2nd group), 10th (3rd group), 20th (4th group) and 30th day (5th group) after the completion of the experiment under anesthesia (intramuscularly sodium thiopental, 60 mg/kg). The total hemoglobin level was determined with the Mythic 18 hematological analyzer. Determination of the content of oxyhemoglobin, methemoglobin, sulfhemoglobin and carboxyhemoglobin was performed spectrophotometrically. The obtained data indicate significant changes in both the total level of hemoglobin and its ligand forms, in particular, a decrease in the level of oxyhemoglobin and the accumulation of dyshemoglobins, such as methemoglobin, sulfhemoglobin, and carboxyhemoglobin. As evidenced by the obtained results, the consumption of energy drinks leads to the oxygen homeostasis violation, the development of tissue hypoxia and can cause structural and functional disorders in the body under such conditions.
