    The influence of herbicide butachlor on the myocardial activity of the loach

    【Abstract】  Objective  To inquiry into the physiology toxicity of the herbicide butachlor on the myocardial of the loach.Methods  In this text,we applied calculator living creature signal analysis system,observed the influence of the herbicide butachlor  on  the myocardial  contractility and  heart rate of  the  loach.Results  It enunciated that butachlor can  change the physiology function of myocardial, making the myocardial contractility to die down,the heart rate messed.Conclusion  It suggests that using the herbicide should notice the environmental protection.
