Title

ECG ALTERATIONS AND CHANGES IN BIOCHEMICAL PARAMETERS ASSOCIATED WITH EXPERIMENTAL SALINOMYCIN TOXICOSIS IN SHEEP

Pages

  120-125

Abstract

SALINOMYCIN is a monocarboxylic polyether ionophore with antimicrobial properties. It is a dietary additive used as a growth promoter for ruminants and as a coccidiostat in chickens. The mechanism of action of ionophores at the cellular level is to selectively bind certain ions creating intra and extracellular biochemical disturbances. Clinical signs of ionophore intoxication are non-specific and similar in all species and include tachycardia, muscle tremor, restlessness, loss of appetite, incoordination, muscular weakness and continual panting. The present study was conducted to determine the changes in ECG parameters and possible ARRHYTHMIAs and their types due to experimental SALINOMYCIN toxicosis in SHEEP. Acute toxicity with the ionophore (0.5 mg/kg; intravenously) was induced in 6 mixed breed female SHEEP. A corresponding volume of sterile saline was intravenously injected in each control SHEEP (n=6). Blood samples were collected before and at various time intervals after the administration of either SALINOMYCIN or saline solutions. Following centrifugation, serum BIOCHEMICAL PARAMETERS (ALT, AST, CK, LDH and total protein) were measured using conventional laboratory methods. In both groups, the heart sounds of SHEEP were carefully monitored and the electrocardiogram (ECG) was recorded. SALINOMYCIN caused a significant (P<0.05) increase in the levels of ALT, AST, LDH and CK in the experimental animals. The mean heart rate in the control group was significantly lower than that in the experimental SHEEP. Numerous ARRHYTHMIAs such as sinus tachycardia (11 cases), ventricular premature contraction (2 cases) and T-wave inversion (3 cases) were recorded in the experimental SHEEP. Acute SALINOMYCIN intoxication seems to cause numerous ARRHYTHMIAs in SHEEP which might be due to the pathological effect of the ionophore on the myocardium.
