Abstract: We determined the effect of chronic liquid nutrition (Fresubin) intake in different developmental stages on the cardiovascular and renal system of male Wistar rats. Body weight, water intake and blood pressure were periodically measured. Selected serum and urine biochemical parameters reflecting metabolic and homeostatic changes after Fresubin intake were investigated as well. Heart and kidney weight, diameter of cardiomyocytes, diameter and length of cardiomyocyte nuclei, wall thickness of thoracic aorta, the diameter and the area of renal corpuscles and serum and urine biochemical parameters were assessed at the end of experiment. We showed that Fresubin intake differently affects the investigated morphological and biochemical parameters in rats and this effect was dependent on the developmental stage when Fresubin was provided. Importantly, we have shown that Fresubin-induced elevation of blood pressure is a reversible phenomenon and it is independent of weight gain and subsequent development of obesity.
