Effects of isoxsuprine hydrochloride on electrocardiographic and trace element status in sheeps.

OBJECTIVE
To study the effect of isoxsuprine hydrochloride on the ischaemic electrocardiographic change and trace element status in sheep.


METHODS
This study was conducted from March 16 to 23, 2012, at Istanbul University, Turkey, and comprised sheep aged 6 months. The animals were divided into two equal groups. The control group was fed a standard diet and had free access to water. In the experimental group, isoxsuprine hydrochloride was injected at a dose of 0.6 mg/kg through the intramuscular route. Electrocardiographic changes, including creatine kinase and cardiac troponin-I, and serum levels of selenium, copper, calcium, magnesium, iron and zinc were investigated in healthy sheep. SPSS 15 was used for statistical analysis.


RESULTS
The 14 sheep were divided into two groups of 7(50%) each. The overall mean weight of the study population was 35±10kg. Selenium, calcium, iron and zinc concentrations did not show any difference in serum samples (p>0.05). However, copper and magnesium concentrations decreased in serum after the administration of the drug (p<0.05). In the experimental group, ST segment depression and abnormal T-wave was found in 6(86%) animals within 60min.


CONCLUSIONS
Isoxsuprine hydrochloride increased cardiotoxicity risk in sheep.
