ABSTRACT
In-vitro toxicity of acetone using isolated rabbit heart is reported. The hearts were perfused using Langendorf's procedure and modified Anderson's coronary perfusion apparatus. Heart rate and force of contraction were recorded mechanically and the coronary flow was measured manually. The force of contraction was significantly reduced; heart rate and coronary flow were significantly increased with acetone concentrations of 0.5% and 1.0% V/V.
