Abstract
Background:
Thioacetamide (TAA) is known to cause damage to various organs, including the testes, posing a significant health threat. On the other hand, Curcuma longa (Cl) has been recognized for its antioxidant properties, suggesting a potential protective role against TAA-induced toxicity in the testes.
Aim:
This study aims to investigate the effect of TAA on testicular function and structure while exploring the therapeutic and protective potential of C. longa versus TAA toxicity.
Methods:
Thirty-two male albino rats, with an age range of 11–12 weeks and a weight range of 180-200 g, were randomly allocated into four distinct groups. The control group received normal saline, while the Cl group ingested Cl orally at a dose of 500 mg/kg daily. The TAA group, received TAA through intraperitoneal injections at a dose of 200 mg/kg body weight three times per week. Lastly, the Cl with TAA group received Cl orally 2 hours before the TAA injections. After 8 weeks of treatment, we anesthetized the rats and saved blood samples for biochemical analysis.
Results:
The study revealed significant alterations in various biochemical parameters in the TAA-treated group, as compared with the control. Specifically, there was a significant increase in bilirubin, albumin, cholesterol, triglyceride, very low-density lipoprotein (VLDL-C), white blood cells (WBCs), low-density lipoprotein cholesterol (LDL-C), and platelets (PLT) levels. Conversely, the Cl-treated group exhibited significant reductions in these parameters, along with notable increases in red blood cells (RBCs), high-density lipoprotein cholesterol (HDL-C), and hemoglobin (HB).
Conclusion:
C. longa demonstrates a protective effect on the testes against TAA-induced toxicity, potentially attributed to its antioxidant properties. This suggests a promising avenue for the use of Cl in mitigating the harmful effects of TAA on testicular function and structure.
