Özet

In the present study, the influence of two different PGRs, indoleacetic acid (IAA) and kinetin (Kn) on immune potential enzymes, adenosine deaminase (ADA) and myeloperoxidase (MPO), and antioxidant defense enzymes such as glutathione peroxidase (GPx), glutathione reductase (GR), and superoxide dismutase (SOD) in various tissues of rats were investigated during the treatment as a drinking water model. 100 ppm of IAA and Kn as drinking water were administered orally to rats (Sprague-Dawley albino) ad libitum for 21 days continuously. The PGRs treatments caused different effects on the immune potential and antioxidant defense enzymes of experimented rats compared to controls. Results show that IAA caused a significant decrease in GR activity in the lungs and liver and an increase in the spleen. Also, IAA caused a significant decline in GPx activity in the lungs and an increase in the heart. SOD was significantly reduced in the heart, while increased in the lungs. Furthermore, IAA caused a significant decrease in ADA activity in the heart and blood whereas an increase in the kidney and spleen. MPO activity was also significantly increased in the heart by IAA treatment. The activity of enzymes were also seriously affected by Kn; GR activity decreased in the lungs, brain, and blood while GPx activity decreased in the spleen, brain, and heart. ADA activity was also significantly reduced in the blood whereas MPO activity rose in the spleen. In addition, SOD activity lowered in all tissues except for lungs where a significant increment was determined. As a conclusion, the results indicate that PGRs might affect on antioxidant and immune potential enzymes. These data, along with the determined changes suggest that PGRs produced substantial systemic organ toxicity in the erythrocyte, liver, brain, heart, lungs, spleen, and kidney during the period of a 21-day subacute exposure.
