From: Myocardial performance in conscious streptozotocin diabetic rats
Responses of heart rate and mean arterial pressure to β1-adrenergic stimulation with dobutamine (1 and 15 μg/kg) in conscious control (treated with vehicle) rats, and conscious diabetic rats obtained by means of streptozotocin (STZ), treated (STZ+Insulin), or not (STZ-diabetic), with insulin. Data are reported as means ± SEM. *P < 0.05 compared to the other groups stimulated with 1 μg/kg; +P < 0.05 compared to their counterparts stimulated with 1 μg/kg.
