\begin{abstract}
In this study, Doxorubicin is used as an effectual induction of cardiotoxicity and heart malfunction in the taken experimental rats which is an anthracycline chemotherapeutic mediator used to the treat of a wide variety of malignancies. To examine the shielding property of ethanolic flower extract of clitoraternatea  (EECT) scheduled doxorubicin(DOX) persuaded cardiotoxicity via albino wistar rats,through inspect the enzymatic,non-enzymatic antioxidant position,serum enzyme and Histopathology tissue.Experimental rats been provoked cardiotoxicity by means of a generous single dose of doxorubicin (15mg /body weight ) and treated orally through an ethanolic extract of clitoraternatea (EECT) for 14 days (100 mg/kg bw, 200 mg/kg bw and 300mg/kg bw,n=5). On 15 days, the rats are sacrificed by treated through Ketamine {\textendash}Xylazine,Biochemical as well as histological remarks of the heart tissues had carry out. Management through EECT of 200mg/kg and 300mg/kg considerably reduced the levels of cardiac marker enzymes(p{\textless}0.05) and as well minimize the decrease of weight of the heart of DOX treated group. In heart tissue superoxide dismutase, glutathione and catalase heights be significantly greater than before and lipid oxide peroxide (LPO) significantly decreased in the extract (200 \&300 mg /kg bw).

\section{Introduction}
 Doxorubicin- an anti-cancer candidate drug, which furthermore provoke myocardial damage in addition to that it is generally used as a chemotherapeutic mediator for a broad spectrum of hard cancer and malignancies, Doxorubicin having iron-anthracycline complex produces oxidative stress, which in turn, causes ruthless injure to the membrane layer, and hinder with the morphology of cytoskeleton  \unskip~\citep{722042:17127605}. The iron-anthracycline complex provoke oxidative stress and produce free radicals by doxorubicin \unskip~\citep{722042:17127112} which aim the heart tissue to lipid peroxidation cause permanentdamage to myofibrils, cytoplasmicdialation with sarcoplasmic reticulumvacuolization, increased quantity of lysosomes, myocyte necrosis also inflammation of mitochondria,\unskip~\citep{722042:17127113}, biosynthesis of protein and nucleic acid also hindered \unskip~\citep{722042:17127114}, adrenergic alteration,Na+K+ATPase also shrink \unskip~\citep{722042:17127111}, modification in calcium transfer of sarcoplasmic along with the difference in electrolytes balance of heart musclesof doxorubicin induction\unskip~\citep{722042:17127604}. The cell transformed doxorubicin into semiquinone by enzymes present in mitochondrial and lysosomal. The electric Semiquinone voluntarily contributes oxygen to an electron, resulting in the making of oxidative stress to cause free radicals liberation. Superoxide dismutase catalyzed the configuration of hydrogen hydroxide from Superoxide \unskip~\citep{722042:17127603}.CVD is a group of disorders or diseases of the heart and blood vessels, which also include atherothrombotic  diseases such as myocardial and cerebral infarction commonly called heart attack and stroke in that order. The events like atherosclerotic plaque creation, endothelial dysfunction \unskip~\citep{722042:17127636}. Atherosclerosis is an inflammatory disease of the large arteries describeatherosclerotic plaques formation. The possible foundation of endothelial dysfunction leading to atherosclerosis contains enhanced free radicals, elevated and modified low mass lipoprotein-cholesterol, hypertension, diabetes mellitus, genetic alterations and prominent plasma homocysteine absorption \unskip~\citep{722042:17127637}. In the majority of cases, atherosclerosis-related clinical events, such as MI or ischemic stroke, are caused by the burst of a vulnerable atherosclerotic lesion \unskip~\citep{722042:17127635}. Butterfly pea (Clitoriaternatea Linn) is used as folk medication. The family tree and germ are use as the stress tonic and laxative. Flowers of butterfly pea restrains anthocyanins. The red violet-blue color of plant and flower is because of Anthocyanins \unskip~\citep{722042:17127640}. (A2, A1,B2,B1,D2 and D1) are the main anthocyaninsternatins  \unskip~\citep{722042:17127641}. The diversity of shades of the flower is owed to a very small digit of a different tincture. These tincture contain the matching carbon skeleton, with diverse only in the character of the substituent grouping \unskip~\citep{722042:17127641} . The current job be accept to revision the cardioprotective role of EECT on cardiac toxicity induced by doxorubicin.
    
\section{Materials and Methods}
\textbf{ Plant}

Clitoraternatea flowers be purchased from koyambedumarket, Chennai, Tamilnadu and were authenticated Dr.V.Gangadevi, Assistant Professor, Botany Department, Aringnar Anna Government Arts College, Cheyyar, Tamilnadu. The herbarium have be present on behalf of auxiliary indication. The flower were shade dried and fine pulverized using pulverize and maintained in an airtight container at 4\text{\textordmasculine} C and used for further study.

\textbf{Preparation of extract}

The finely powdered dried flowers of clitoraternatea convert to crude powder. The crude powder was extracted with solvent ethanol through soxhlet until them colorless. Then it was pressure evaporated by rotary evaporator below 45\text{\textordmasculine}C wait the formation of syrupy of the extract and transferred it in a clean dish at room temperature.17.3\% w/v was the yield originated.

of ethanol extract of clitoraternatea were vocally directed to groups of similar age and weight. The taken rats were supervised for 60 minutes continuously and after that hourly for 4 hour and finally for every 24 hours until the final protocol for some warning sign of toxicity and transience \unskip~\citep{722042:17127639}. The indication of embarrassment to the animals were originate at a dosage of the 2000mg/kg bw EECT. Therefore the dose of 1000mg/kg bwup to 1,000 mg/kg was chosen to be safe also the dose of 100, 200 \& 300 mg/kgbw of EECT taken to study the cardioprotective commotion.

\textbf{Experimental Protocol}

 The experimental protocol applies for assessment of cardioprotective effect of ethanolic extract clitoraternateaagainst DOX-induced cardiotoxicity is as follows. The rats were erratically allocated into six groups of five each.

Group I: Control group received distilled water for 14 days.

Group II: DOX-induced group received a single dose of DOX 15mg/kg I.P on 1\ensuremath{^{st}} day only.

GroupIII: Standard Drug treated group received a single dose of DOX 15mg/kg I.P on 1\ensuremath{^{st}} day, Metoprolol (10 mg/kg bw) for the other 13 days.

GroupIV: Treated Group1received DOX 15mg/kg I.P on the 1\ensuremath{^{st}} day and 100mg EECT for other 13 days.

GroupV: Treated Group2 received DOX 15mg/kg I.P on the 1\ensuremath{^{st}} day and 200mgEECT for other 13 days.

GroupVI: Treated Group3 received DOX 15mg/kg I.P on the 1\ensuremath{^{st}}day and 300mgEECT for other 13 days.

At the end of the 14\ensuremath{^{th}}day, the animals were anaesthetized Ketamine {\textendash} Xylazine and then sacrificed by a high dose of ketamine. Blood samples were collected immediately for enzyme assays. The serum was prepared by centrifuging the blood samples at 3000 rpm for 5 min. The heart of the rats were rapidly dissected and washed in isotonic saline and homogenized quickly with ice-cold 0.1M Tris HCl buffer (pH-7.5) and stored.

\textbf{Cardiac biochemical markers }

The LDH, AST and CK-MB actions were dogged from serum according to normal technique using standard kits.

\textbf{Lipid peroxide content}

Lipid peroxide enzyme levels was determined by thiobarituricacid  (TBA) reaction with Malondialdehyde (MDA), a creation create dowing to the peroxidation of lipid membranes \unskip~\citep{722042:17127643}.

\textbf{Catalase activity}

The CAT activity of cardiac tissue was resolute according to the method described by Aebi \unskip~\citep{722042:17127646} the method based on the determination of the H\ensuremath{_{2}}O\ensuremath{_{2}} decomposition rate at 240 nm. The values are expressed as U/mg protein.

\textbf{Glutathione content}

 Reduced Glutathione was estimated by the method of Ellma \unskip~\citep{722042:17127645}  About 1.0 ml of 10\% TCA was added to 1.0 ml of homogenate and centrifuged. The supernatant was treated with 0.5 ml of Ellmans reagent and 3 ml of phosphate buffer (pH-8.0).  The color developed was measured at 412 nm.

\textbf{Superoxide dismutase activity}

The SOD was determined by the ability of the enzyme to inhibit the oxidation of adrenaline to adrenochrome \unskip~\citep{722042:17127644}. The 0.05 ml supernatant was added to 2.0 ml of carbonate buffer as well as 0.5 ml of 0.01MEDTA solution. 0.5 ml of epinephrine was added for the initiation of reaction. The auto-oxidation of adreno chrome was measured by following change in OD at 480 nm. The results are expressed at U/mg protein.

\textbf{Assay of total protein}

To 0.3 ml of solution of tissue homogenate to that alkaline copper sulphate, 2ml kept for 10 min at RT then 02. Ml for folinciacalteau added and kept for 30 min incubation and read at 660nm with standard BSA.The assay of total protein carried out by the \unskip~\citep{722042:17127947}.

\textbf{Histopathology of Heart tissue}

On the 15\ensuremath{^{th}}Day,the heart is cut off, clean with isotonic saline also homogenized among 1 M Tris Hcl buffer. Followed via the tissues be presented in 10\% buffer unbiased formalin solution. Following complex tissues be fixed in paraffin {\textendash}wax and segments be hacked and stain by hematoxylin and eosin. The stained tissue coated slides were examined with microscopy.

\textbf{Statistics}

The collected data were articulated as the mean \ensuremath{\pm} SD for analysis of statistical data, group were balanced by ANOVA, tag alonged by Dunnett's test. The p values \textless\ 0.05 was measured considerable.

Phytochemical examinations exposed the occurrence of steroids, tannins, flavonoids, phenolic compounds, carbohydrates, glycosides, alkaloids, sapponins,and terpenoids.

In DOX-induced group, the mammal's hair change into muddled and yellowish to ruddy dark development is also seen. The Animals have dark exudatesroughly the eyeball along with nudge, elasticfluid feces, the existence of peritoneal watery, necrosis at the location of insertion. Animals are in pitiable health, slow-moving and swelling of liver and stomach that distinguish among the control animals. The above annotations be noticeably compacted in the group treated with EECT (200 \&300 mg /kg bw) when contrasted with DOX-induced animals group.

 In Doxorubicin-induced rats, there is a reduce the mass of the body, heart tissue and ratio of their weights on final day(Figures~\ref{f-9f481d4cccea} and~\ref{f-3d811fc33463}).EECT (200 mg/Kg and 300 mg /Kg ) established major boost mass of body, heart and its ratio (p{\textless}0.05 ) when contrast with DOX-induced group (Table~\ref{tw-8d4472f58745}).

(Table~\ref{tw-c68a8de1066b}) illustrated the results of EECT on the point of CK-MB \& AST enzymes. Treatment among DOX origins with altitude in the amount of oxidative enzymes which be calculated as the careful myocardial injure biomarkers when contrast compare to standard. This protocol illustrated reduce in a superior amount of the above oxidative enzymes. Treatment among the EECT 300 mg/Kg demonstrated considerable diminish in (p{\textless}0.05) AST, LDH and CK-MB (Figure~\ref{f-82bad1279eb5}).

Doxorubicin induces endogenous oxidative stress decreased level of SOD, CAT and GSH had shownen hanced LPO in the heart tissue(Figures~\ref{f-194627d946a8} and~\ref{f-7599f2a1edd6}). Treatment of EECT 200 and 300 mg/kg illustrate a significant increase (p{\textless}0.05) in SOD, CAT and GSH, the level of LPO will decreased significantly (p{\textless}0.05), while compared with Control group. SOD, CAT and GSH be there a vital antioxidant biomolecules in the tissue adjacent to oxidant stress particularly in cardiac tissue (Table~\ref{tw-fdf34d80e381}).

The protein content in the DOX-induced rats demonstrated a decrease in the protein levels when compared to control. Animals treated at a dose of 200 7 300 mg/kg bw of EECT illustrate a considerable high in the levels of protein in contrast to DOX-induced group.

\textbf{Histopathological Studies}

Histopathological assessments of heart tissue achieved as standard control animals established an understandable stead fastness of myocardial covering. Standard control animals demonstrated standard cardiac fiberssmart of which even harmed. Cardiac muscle section ofDOX-induced ratsdemonstrate sufficient region of necrosis with aggregations,cells with severe inflammation and vascular spaces also injured. Rats treated with EECT of 200 \& 300mg/kg bwshown an enlargement of the cells reliability established by be short of necrosis, inflammatory cells are noticeable diminish in size and protect the usual morphology of the heart tissue (Figure~\ref{f-ecccd9d6836d}).

 The ethanolic flower extract of ClitoriaTernateahave exposed momentous cardio protection through Doxorubicin-induceded cardiac toxicity. Single admin of Doxorubicin(15mg/kg bw) will demonstrate as a  source of cardio toxicity in rats \unskip~\citep{722042:17127944}. In this experiment, we developed a Cardiotoxic rat model by injecting a single dose of 15mg/kg bw of DOX and it has been shown to as significantly diminished body, heart and ratio of their masses. The diminish in the mass of the body in this study is in agreement by means of additional studies \unskip~\citep{722042:17127945}and this is because of food eaten by the animals and it may diminish protein production due to Doxorubicin. The ethanolic extract will demonstrate a amplification in the mass of the body, heart and ratio.

DOX induction created a considerable increase of Creatinine kinase \unskip~\citep{722042:17127944}, LDH\unskip~\citep{722042:17127946}. An elevated level of this oxidative enzymes will back to normal by EECT treatment significantly. This mitochondrial dysfunction and oxidative stress is because of the DOX induction causing sick to the rats. DOX will cause membrane lipid peroxidation, production of ROS and also the reactive aldehyde \unskip~\citep{722042:17127990}.SOD and CAT enzymes shown a significant decrease but an increase in LPO on DOX-induced group when compare to the Normal control group. Treating EECT on DOX-induced group considerably get the level of these enzymes back to normal. This provides evidence that the avoidance of oxidative injure by EECT. The cardiac tissue Histopathology observation of the groups shown a significant changes in EECT treated when compared to DOX-induced group. The heart sections acquired since Doxorubicin-induced animals demonstrated commotion of numerous subcellular feature which includes myofibrils loss ,mitochondria swelling, cytoplasmic vacuolization, sarcotuburdialation and lysosomal formation\unskip~\citep{722042:17127989}.The architecture of the heart close to normal with control group while treating with 200mg/kg and 300mg/kg bw of EECT. The presence of phytochemical constituents like Triterpenoids, Flavonoids, Tannins, Soponins, glycosides, sterols, carbohydrates, alkaloids, proteins and carbohydrates will strength the cardio protectively of EECT in DOX-induced Cardiotoxicity of the taken experimental animals.
    
\section{ Conclusions}
EECT demonstrated a persuasive anti-cardiotoxic outcome in the taken experimental animal by DOX persuaded cardiotoxicity / myocardial necrosis. Treatment with EECT may effect LDH, CK-MB and AST activity. This put forward that EECT might be the reason in the reduction and avoidance of the severe cardiac complications encountered by Doxorubicin. The EECT extract is a novel strategy with the aim for defending against Doxorubicin-induceded cardiotoxicity. In conclusion the over statistics put forward to facilitate EECT has the potential antioxidant movement in avoiding the cardiotoxic possesses on persuade by Doxorubicin.
