Summary of article contents:
1) Introduction
Hypothyroidism is a condition characterized by insufficient production of thyroid hormones, affecting both humans and animals. The conventional treatment involves the administration of synthetic thyroid hormones, specifically levorotatory thyroxine (L-T4) and triiodothyronine (L-T3). However, these treatments can lead to side effects and pose economic burdens on patients. Herbal remedies have been utilized in traditional medicine to address various health issues due to their safety profiles and efficacy. This study focuses on evaluating the effects of two isolated compounds, Phyllanthin and Hypophyllanthin, extracted from the plant Phyllanthus amarus, on thyroid activity in hypothyroid Wistar rats induced by propylthiouracil.
2) Thyroid Hormone Modulation
The thyroid gland releases hormones that regulate metabolism and essential bodily functions. When hypothyroidism occurs, it prompts a compensatory increase in thyroid-stimulating hormone (TSH) levels due to the pituitary gland's feedback mechanism. The study investigated the effects of Phyllanthin and Hypophyllanthin on serum levels of T3, T4, and TSH amid propylthiouracil-induced hypothyroidism. Both compounds demonstrated significant increases in serum T3 and T4 levels while reducing TSH levels. This suggests that the isolated compounds can influence thyroid hormone dynamics, exhibiting thyroid hormone-like activity and potentially mitigating hypothyroidism's impact.
3) Impact on Thyroid Weight and Body Metrics
Hypothyroidism is associated with an increase in thyroid weight, indicating the gland's response to hormone deficiency. In this study, the administration of Phyllanthin and Hypophyllanthin resulted in reduced thyroid weight, approaching normal levels compared to control groups treated with propylthiouracil alone. Additionally, the effects of hypothyroidism on body weight, food intake, and water intake were evaluated. The compounds helped restore animal weights and normalize feeding behaviors, which were altered in hypothyroid conditions. Their administration resulted in increased food and water intake, further supporting their influence on metabolic functions.
4) Effects on Total Protein and Cholesterol Levels
Hypothyroidism is known to elevate total serum protein and cholesterol levels. The study assessed the impact of Phyllanthin and Hypophyllanthin on these parameters. Both compounds led to a significant reduction in total protein and cholesterol levels in treated rats, indicating their potential role in normalizing metabolic disturbances associated with hypothyroidism. This reduction suggests a restoration of hepatic function affected by thyroid hormone imbalances, demonstrating that these herbal components may beneficially influence lipid metabolism and protein levels.
5) Conclusion
The study highlights the significant therapeutic potential of Phyllanthin and Hypophyllanthin in managing hypothyroidism. By enhancing serum T3 and T4 levels while reducing TSH, the compounds exhibit thyroid hormone-modulating properties. Their effects on thyroid weight and lipid/protein metabolism further reinforce their efficacy. Given the observed differences in responses based on sex—in which females showed a more pronounced effect—these compounds merit further investigation in human clinical trials to assess their safety and effectiveness in treating hypothyroidism. Ultimately, the findings support the transition toward herbal therapies that alleviate the challenges associated with conventional treatments.
