OBJECTIVE: We investigated the effects on skeletal muscle of gadolinium based linear and macrocyclic radiocontrast agents applied at experimental intervals using histopathological methods. METHODS: Thirty-two male Sprague–Dawley rats were included in the study for histopathological analysis. No procedure was performed on the healthy control group. The sham group received 0.1 ml/kg intravenous (IV) saline solution through the tail vein 4 times weekly for 5 weeks. The gadodiamide group received total 2 mmol/kg IV gadodiamide through the tail vein 4 times weekly for 5 weeks. The gadoteric-acid group received 2 mmol/kg IV gadoteric acid through the tail vein 4 times weekly for 5 weeks. RESULTS: We determined no marked apoptotic myofibrils associated withcaspase-3 expression in these two groups. Furthermore, no calcineurin expression was observed in myofibrils in the two groups. However, quantitative analyses revealed a decrease in muscle-fiber area in the gadodiamide and gadoteric-acid groups compared to the control group (Respectively; p=0.001 and p=0.017). CONCLUSION: In our experimental study, linear and macrocyclic GBCAs applied at repeated doses played no role in myofibril damage induced by caspase-3 and calcineurin – nuclear factor of activated T-cells in skeletal muscle tissue. |
