The Effects of Some Plant Growth Regulators on the Level of Glycogen Protein and Lipid in Various Tissues of Rats

Abstract

The study was carried out to investigate whether plant growth regulators (PGRs) could affect carbohydrate, protein and lipid metabolism in liver and muscle tissues. Forty-eight Sprague-Dawley albino rats were divided into four experimental groups; control and PGR-treated [indole acetic acid (IAA), indole butyric acid (IBA) and kinetin (Kn)]. 100 ppm of PGRs was administered orally to 12 rats ad libitum for 25 days continuously. The PGR treatments caused different effects on the level of protein, glycogen and lipid in comparison to those of control rats. According to the results, while the level of lipid and glycogen in muscle and liver of rats exposed to IAA increased statistically, the protein levels remained unchanged in both muscle and liver in comparing with the controls. IBA treatment caused a statistically important decrease in the levels of protein in liver, and an increase in the glycogen level in muscle. Also, kinetin caused a statistically important decrease in the glycogen level in liver and muscle. The protein and lipid levels remained unchanged in both muscle and liver. It is concluded from this study, that PGRs may cause toxicity in different tissues of rats.
