title: Calcium uptake activity of cardiac sarcoplasmic reticulum in myo-inositol-treated diabetic rats.
abstract: 1. Cardiac function of STZ-diabetic rats has been shown to be partially improved by myo-inositol treatment. We studied the effect of myo-inositol on Ca2(+)-uptake activity in sarcoplasmic reticulum in diabetic animals. 2. Cardiac sarcoplasmic reticulum Ca2(+)-uptake activity was significantly depressed in 8-week diabetic rats. 3. Myo-inositol treatment could not improve Ca2(+)-uptake activity in diabetic rats. 4. The data suggest that the cardiac dysfunction in diabetic rats is due to factors other than the decreased Ca2(+)-uptake activity in sarcoplasmic reticulum.
