ABSTRACT
Cancer is the most serious disorder that may affect a person and is also the leading cause of mortality. Worldwide, breast cancer continues to be the leading cause of cancer-related deaths in women. The popularity of treating diseases using alternative and complementary medicines has increased in recent decades; many of these are derived from plants. Chamomile has a beneficial effect in treating many diseases, there for the purpose of this work is to study how chamomile protect against cardiac damage and toxicity brought on by Ehrlich solid tumor (EST) in adult female mice. 40 female mice were distributed in 4 groups (control, chamomile, EST, EST+chamomile). The research results indicated that EST caused significant alterations in cardiac function and structure. EST induced a significant elevation in serum creatine kinase (CK), creatine kinase MB (CK-MB), lactate dehydrogenase (LDH), alkaline phosphatase (ALP), and myoglobin (MB), potassium, chloride ions, cholesterol, triglycerides, low-density lipoprotein (LDL), cardiac tissue damage, apoptotic P53 and Caspase 3 expressions while levels of sodium ions and high-density lipoprotein (HDL) were significantly decreased. Treatments of EST with chamomile improved the biochemical, histopathological, and Immunohistochemical alterations. This suggests that chamomile may be useful as an adjuvant for the treatment and prevention of cardiac toxicity.
