Myocardial potency of Caesalpinia bonducella Linn. on doxorubicin induced myocardial infarction in albino rats

Abstract

Caesalpinia bonducella L. is well known and extremely valuable herb in ayurvedic system of medicine. The present study is aimed to design the evaluation of aqueous extract of Caesalpinia bonducella L. on doxorubicin induced myocardial infarction in wistar strains of albino rats of both sex. The experimental animals are divided in to 5 groups of 6 animals each. Group I (Normal Control), Group II (Negative Control, 2.5 mg/kgbw of Doxorubicin i.p.), Group III (2.5 mg/kgbw of Doxorubicin i.p.) + AECB (150 mg/kgbw), Group IV (2.5 mg/kgbw of Doxorubicin i.p.) + AECB (300 mg/kgbw), Group V (2.5 mg/kgbw of Doxorubicin i.p.) + standard drug (Propranolol 5 mg/kgbw). Doxorubicin induced myocardial infarction was confirmed by disturbances in levels of cardiac markers (Lactate Dehydrogenase, Troponin-T, Creatine Kinase-MB Isoenzyme, Creatine Phosphokinase), nucleic acid contents (DNA and RNA), Challenged levels of Membrane bound enzymes such as Na+/K + ATPase, Ca2 + ATPase and Mg2 + ATPase, Decreased tissue protein and altered lipid profile markers. Doxorubicin induced rats significantly showed increase in the activities of LDH, CK-MB, CPK, Troponin-T, nucleic acids, membrane bound enzymes, lipid profiles and decrease in the serum HDL. Treatment with AECB simultaneously at two different doses such as 150 mg/kg bw, 300 mg/kg bw prevented the leakage of myocardium markers and altered the levels of Protein, DNA, RNA and membrane bound enzymes. The AECB prevented the altered variations in Cholesterol, Triacylglycerols, Phospholipids and Free Fatty Acids. This extract also brought back the levels of Lipoproteins like HDL, LDL and VLDL which were varied in disease control animals. The present study concludes that AECB is effective in controlling the cardiac markers and lipid levels which could be due to its ability to maintain the membrane stability and repair the myocardial damage.
