    Background: Cardiotoxicity is one of the most feared side effects of anticancer agents like Doxorubicin. Asparagus racemosus is a widely used medicinal plant in Indian system of medicine known for its antioxidant activity. In certain studies ethanol extract of Asparagus racemosus has shown to possess cardioprotective activity in experimental animals while in some other studies cardioprotective potential of Asparagus racemosus has not been demonstrated. Therefore, due to the controversial action, the present study was designed to explore the cardioprotective effect of aqueous effect of Asparagus racemosus against doxorubicin induced cardiotoxity.Methods: Following approval from Institutional Animal Ethics Committee of L.L.R.M Medical College registered under CPCSEA, India, this study was conducted in which 30 rats were randomized into five groups of six rats each. Group I received 2 ml/kg b.w. normal saline p.o for 21 days, group II apart from receiving pellet diet and normal saline for 21 days were treated with Doxorubicin in a single dose of 20 mg/kg intraperitoneally on the 21st day, group III and group IV received aqueous extract of Asparagus racemosus in doses of 250 mg/kg/day and 500 mg/kg/day respectively p.o. for 21 days followed by administration of Doxorubicin (20 mg/kg i.p.) on the 21st day, Group V received Carvedilol in doses of 30 mg/kg/day p.o. for 21 days followed by administration of Doxorubicin (20mg/kg i.p) on the 21st day. Then they were anaesthetized and blood sample was collected from abdominal aorta for performing blood test i.e. Creatinine kinase MB fraction (CK-MB), Lactate dehydrogenase (LDH), Serum glutamate oxaloacetate transaminase (SGOT), Serum glutamate pyruvate transaminase (SGPT). After blood collection the animals were sacrificed and heart was dissected out for histopathological study. The data obtained was organized and analysed by suitable statistical methods i.e. ANOVA followed by Post Hoc test.Results: CK-MB, LDH, SGOT and SGPT levels were found to be significantly raised (p<0.001) in Doxorubicin treated group. Asparagus racemosus pretreated groups exhibited significant limitation (p<0.001) in rise in levels of CK-MB,LDH,SGOT and SGPT levels in a dose dependent manner following Doxorubicin administration which were comparable to the group treated with the standard cardioprotective drug Carvedilol. Histopathological changes further corroborated cardioprotective potential of Asparagus racemosus.Conclusions: The present study concluded that aqueous extract of Asparagus racemosus possess cardioprotective potential against Doxorubicin induced cardiotoxicity.

    Evaluation of cardioprotective effect of Aegle marmelos on doxorubicin induced cardiotoxicity: an experimental study
    (Medip Academy, 2018-07) Vishwakarma, Pinki; Divekar, Pratik; Goel, Raj Kumar; Sharma, Monica; Saini, Manish; Saxena, K. K.
    Background: Aegle marmelos (A. marmelos), a medicinal herb, is widely used in the Indian system of medicine for treatment of various ailments. The methanolic extract of A. marmelos leaves had shown antioxidant effect. However, so far aqueous extract of A. marmelos is not scientifically evaluated for its cardio protective potential. Hence the present study was designed to find out cardio protective role of A. marmelos against doxorubicin induced cardiotoxicity.Methods: Thirty rats were randomized into five major groups (n=6). Group I received only 2ml/100g/day normal saline p.o., group II received 2ml/100g/day of normal saline p.o. followed by doxorubicin on 21st day, group III received carvedilol 30 mg/kg/day p.o., Group IV received A. marmelos 250mg/kg/day p.o. and Group V received A. marmelos 500mg/kg/day p.o. for 21days. Doxorubicin 20mg/kg i.p. single dose was given to induce cardiotoxicity in rats of group II, III, IV and V respectively on last day of experiment. Animals were sacrificed 48 hours after doxorubicin administration. Cardiac serum markers creatinine phosphokinase MB, lactate dehydrogenase, serum glutamate oxaloacetate transaminase and serum glutamate pyruvate transaminase were analysed biochemically. Histopathological changes were studied under light microscope.Results: All cardiac serum marker levels were found significantly (p<0.001) increased in doxorubicin group while A. marmelos pre-treated group displayed significant (p<0.001) reduction in rise of these parameters in a dose dependent manner indicating cardio protection. Histological observations further correlated the cardio protective effect of A. marmelos.Conclusions: The present study concluded that aqueous extract of A. marmelos possesses cardio protective potential against doxorubicin induced cardiotoxicity.

    Evaluation of nephroprotective activity of Tinospora cordifolia against gentamicin induced nephrotoxicity in albino rats: an experimental study
    (Medip Academy, 2019-06) Sharma, Monica; Pundir, Jyoti; Vishwakarma, Pinki; Goel, Raj Kumar; Saini, Manish; Saxena, K. K.
    Background: Gentamicin induced nephrotoxicity is a major contributor to Acute Kidney Injury (AKI) resulting from free radicals induced oxidative stress. Tinospora cordifolia is an Indian medicinal plant, widely used because of its antioxidant activity. Due to limited scientific literature exploring its nephroprotective potential, the present study was designed to investigate the nephroprotective effect of aqueous extract of Tinospora cordifolia against gentamicin induced nephrotoxicity in albino rats.Methods: The study was commenced following approval from Institutional Animal Ethical Committee of L.L.R.M. Medical College, Meerut (UP). Twenty four rats were randomised into four groups of six animals each. Total duration of study was 21 days. Group I received normal saline p.o., group II received normal saline along with gentamicin on last 5 days, group III and IV received Tinospora cordifolia in graded doses p.o. along with gentamicin on last 5 days. Injection gentamicin (40mg/kg) i.p. was given once daily for last 5 days to induce nephrotoxicity in rats of groups II, III and IV. The rats were sacrificed under anaesthesia, blood samples analysed for blood urea nitrogen (BUN) and serum creatinine levels and histopathological changes were studied. Statistical analysis was done using ANOVA followed by post hoc test.Results: Tinospora cordifolia pre-treated groups exhibited significant (p<0.001) limitation in rise in levels of BUN and serum creatinine in a dose dependent manner. Histolopathological observations further corroborated the biochemical findings.Conclusions: The present study concluded that aqueous extract of Tinospora cordifolia possesses nephroprotective potential against gentamicin induced nephrotoxicity.
