How a Doxorubicin-induced dilated cardiomyopathy model is a stable, reliable, and economical.This method will contribute to varying the pathogenesis on dilated cardiomyopathy and to exploring new drugs.Dissolve doxorubicin hydrochloride in sterilized water at a concentration of one milligram per milliliter.Vortex the solution and store it at four degrees Celsius.Maintain eight to 10-week-old mice in pathogen-free mouse cages with a 12-hour light-dark cycle at a constant temperature of 23 degrees Celsius.And provide as much food and water as needed.Before beginning treatment, randomize mice into a control group and a dox group.For mice in the dox group, use one milliliter sterilized syringes to inject the dox solution intraperitoneally.Administer a dose of five milligrams per kilogram of body weight intraperitoneally once per week.Perform the injection in the lower left or right quadrant of the abdomen, taking care of to avoid the urinary bladder and other abdominal organs.For four weeks measure the body weight of the mice weekly and adjust the injection dose accordingly each week.After confirming anesthesia, use depilatory cream to carefully remove the chest fur.After performing echocardiography, use the M-mode tracings to measure the average LV end
