To address this, we evaluated the antigenicity of lac color through active systemic anaphylaxis (ASA) in addition to identifying potential biomarkers performing exploratory studies. For ASA test, Guinea pigs (n = 5) were sensitized with 0(negative control), 4 mg/kg of lac color, 4 mg/kg of lac color + FCA, and 5 mg/kg of ovalbumin + FCA (positive control) 3 times a week for three weeks.

Extraction, preliminary phytochemical analysis, acute toxicity study and body weight (b.w.) of ERBECP were achieved using standard methods. Phyto-constituents in ERBECP were indentified using Gas Chromatography-Mass Spectrometry (GC-MS) technique. Thirty (30) male albino Wistar rats of average b.w. ranging between 100 and 130 g were divided into six groups of five rats each. Groups I, II and III served as normal, doxorubicin (DOX) and standard (Vasoprin 150 mg/kg b.w) controls respectively, while groups IV, V and VI were orally pre-treated with the extract (200, 400 and 600 mg/kgb.w) for two weeks prior to intraperitoneal induction of cardiotoxicity with DOX (20 mg/kg bw) on day 14.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Results: &lt;/strong&gt;Disturbances in serum cardiac function bio-markers such as; Cardiac Troponin-I (CTnI), Creatine Kinase (CK), Lactate Dehydrogenase (LDH), Aspartate aminotransferase (AST), Alanine aminotransferase (ALT).

Oxidative stress markers such as; Malondialdehyde (MDA), Superoxide Dismutase (SOD), Catalase (CAT), Glutathione (GSH) confirmed the induction of myocardial infarction.
