Effects of adriamycin (ADM) treatment on rat heart cells in culture were examined. ADM treatment (lug/ml) for 3 hr, 48 to 51hr of culture age, had no effect on oxygen consumption, myosin content or myosin ATPase activity. In contrast, the activities of creatine kinase, adenylate kinase and adenosine deaminase were significantly lower in ADM-treated cells than in corresponding controls at 72 and 96 hr of culture age. Fall in the activities of these key enzymes of adenine nucleotide metabolism would lead to disturbances in energy metabolism, and results in the functional impairment of heart cells.
