Abstract:
AIM: To study alterations of nitric oxide synthase (NOS) in cardiac sarcop lasmic reticulum from rats with myocardial calcification, and to explore the mec hanism of inhibition of SR function in the rats with myocardial calcification. METHODS: The myocardial calcification rat models were prepared by vit amin D3 plus nicotine for 2 weeks and 6 weeks. Cardiac SR was separated by centrifugating. T he nitric oxide (NO) production, NOS activity and NOS protein expression in the SR were perfor med. RESULTS: Compared with control, myocardial calcium content in t he 6 weeks i ncreased by 408%(P
