Summary of article contents:

1. Introduction

Doxorubicin hydrochloride, an anthracycline anticancer drug, has been documented for its teratogenic effects, which raise significant concerns regarding its use during pregnancy due to the potential to cause developmental defects in the fetus. This study explores the effects of doxorubicin hydrochloride on developing chick embryos, noting morphological malformations, stunted growth, and biochemical changes in the amniotic fluid induced by the drug. Additionally, the research examines the ameliorative role of the herbal plant Vitex negundo Linn. in counteracting the adverse effects of doxorubicin.

2. Teratogenic Effects of Doxorubicin Hydrochloride

The study highlights that doxorubicin hydrochloride induces various malformations in chick embryos during the organogenesis stage. The research noted significant alterations, such as limb deformities, stunted growth, hydrocephaly, and hemorrhaging. These deformities are consistent with other studies that have observed similar abnormalities in various animal models, indicating potential reproductive risks associated with the administration of doxorubicin during pregnancy. Notably, the embryos treated with higher doses of doxorubicin exhibited more severe malformations.

3. Ameliorative Role of Vitex Negundo

The research investigates the protective effects of the alcoholic leaf extract of Vitex negundo Linn. on the biochemical parameters of amniotic fluid affected by doxorubicin administration. The study found that pre-treating the embryos with the herbal extract resulted in the normalization of altered protein, glucose, amylase, lipase, triglyceride, and cholesterol levels. This finding suggests that the antioxidant properties of Vitex negundo may help restore biochemical balance and mitigate the harmful effects of doxorubicin, demonstrating the potential for herbal remedies in protecting against drug-induced toxicity.

4. Biochemical Changes Observed

Significant biochemical changes were observed in the amniotic fluid of chick embryos exposed to doxorubicin hydrochloride. The study recorded elevated levels of proteins, glucose, amylase, and lipase, which indicated cellular damage and impaired metabolism. Conversely, levels of triglycerides, cholesterol, and G6PD decreased significantly in treated embryos, suggesting a disruption in lipid metabolism and enzyme activity. The pretreatment with Vitex negundo extract reversed many of these changes, highlighting its role in minimizing the biochemical impact of doxorubicin.

5. Conclusion

In conclusion, the study demonstrates that doxorubicin hydrochloride has detrimental effects on the developing chick embryos, leading to both morphological and biochemical changes. However, pretreatment with Vitex negundo Linn. extract shows promise as a therapeutic agent in alleviating the adverse effects associated with doxorubicin treatment. This research underlines the necessity for further exploration of herbal remedies as protective agents against the teratogenic effects of chemotherapy, which can inform safer therapeutic strategies in clinical practice.
