BACKGROUND: Different dietary components can affect hematological and biochemical profiles, potentially causing pathohistological changes in liver and kidney tissue.
AIM: The animals in the experiment consumed various bakery and meat products, and ultimately, the potential effects on hematological, biochemical, and pathological parameters were evaluated.
METHODS: The study involved 24 clinically healthy adult rats, randomized into three groups of eight rats each, as follows: rats that consumed meat products (group M), rats that consumed bakery products (group H), and a control group that consumed conventional rodent food (group K) for 7 weeks. After 7 weeks, hematological and biochemical blood analyses were conducted along with pathohistological examinations of the liver and kidneys.
RESULTS: Significant differences (p < 0.05) were observed among groups for several hematological and biochemical parameters, including creatinine (CREA), urea, blood urea nitrogen /CREA, calcium, alanine transaminase, alkaline phosphatase, and lipase. Consuming meat products had a less favorable impact on the occurrence of kidney function disorders. Group H exhibited significant differences in leukocyte and platelet counts compared with groups M and K. Extreme echinocytosis was recorded in group M, whereas sideropenic anemia was prominent in group H. Analysis of the livers of rats in groups K and H did not show significant differences in the observed parameters (gamma-glutamyl transferase and total bilirubin), whereas group M had a significantly higher degree of hepatocyte degeneration and steatosis, and the observed infiltrate was also more pronounced, but not significantly. The kidneys of group M showed discrete alterations of the microstructure, i.e., slightly increased cellularity of renal corpuscles and hypertrophy of proximal nephrocyte, whereas the kidney tissue of group K had a regular appearance.
CONCLUSION: Consuming meat products was associated with adverse liver and kidney changes, whereas bakery products led to sideropenic anemia and altered hematological values.
