The Effects of Quercetin Administration on Heart Tissue and Serum Parameters in the Rats with Experimental Obesity
Öz
Obesity causes structural and functional damage to various organs. Quercetin is a flavonoid and has potent antioxidant, antiapoptotic and anti-inflammatory effects in the body cells. This study aims to investigate the therapeutic effect of Quercetin on
the cardiac effect caused by obesity in rats with experimental obesity using biochemical and histological methods. In this study,
24 male Sprague Dawley rats were used. The rats were divided into three groups i.e., control, obese, and Quercetin-Obese. A
high-fat diet was administrated to the obese groups for 3 months, the other groups were fed with normal pellet forage. After
the formation of obesity, a 50 mg/kg dose of Quercetin was orally fed to the quercetin-obese and quercetin groups for 15 days.
At the end of study, all the animals were sacrificed by taking blood under anesthesia (sevoflurane), and their heart tissues were
taken. In the obtained serum samples, the levels of triglyceride (TG), cholesterol (CHOL), high-density lipoprotein cholesterol
(HDL-C), low-density lipoprotein cholesterol (LDL-C), and cardiac troponin-I (cTnI) were measured by the auto-analyzer
device. The heart tissues were stained with Bax and Bcl-2 antibodies as immuno-histochemical. When the results of the analysis
were compared among the control and other groups, it was shown that obesity increased the levels of serum TG, CHOL, LDLC, and cTnI whereas quercetin administration had a decreasing effect on these parameters (P<0.05). It was determined that the level of Serum HDL-C decreased in the obese group while quercetin administration increased the level of HDL-C (P<0.05).
The analysis of Bax and Bcl-2 immune reactive cells showed that the apoptotic cell density increased in the heart tissues of the
obese group while quercetin administration decreased the apoptotic cell density (P<0.05). This study shows that Quercetin
may have a therapeutic effect in avoiding cardiac injuries caused by obesity
