An alteration in calcium (Ca2+) mobilisation is believed to play an important physiological role in diabetes-induced cardiomyopathy (Ha et al. 1999). In this study we have investigated the role of Ca2+ mobilisation in ventricular myocytes from streptozotocin (STZ)-induced diabetic rats compared with age-matched controls. STZ (60 mg kg-1) was administered intraperitoneally (I.P.) to male Wistar rats (250
