摘要

Background: Chronic fatigue stress (CFS) is an important health problem with unknown causes and unsatisfactory prevention strategies, often characterized by long-lasting and debilitating fatigue, myalgia, impairment of neuro-cognitive functions along with other common symptoms. The present study has been designed to explore the protective effect of statins against running wheel activ- ity induced fatigue anxiety. Methods: Male albino Laca mice (20?30 g) were subjected to swim stress induced fatigue in a running wheel activity apparatus. Atorvastatin (10, 20 mg/kg, po) and fluvastatin (5, 10 mg/kg, po) were administered daily for 21 days, one hour prior to the animals being subjected to running wheel activity test session of 6 min. Various behavioral tests (running wheel activity, locomotor activity and elevated plus maze test), biochemical parameters (lipid peroxidation, nitrite concentration, glutathione levels and catalase activ- ity) and mitochondrial complex enzyme dysfunctions (complex I, II, III and IV) were subsequently assessed. Results: Animals exposed to 6 min test session on running wheel for 21 days showed a significant decrease in number of wheel rota- tions per 6 min indicating fatigue stress like behavior. Treatment with atorvastatin (10 and 20 mg/kg) and fluvastatin (10 mg/kg) for 21 days significantly improved the behavioral alterations [increased number of wheel rotations and locomotor activity, and anxiety like behavior (decreased number of entries and time spent in open arm)], oxidative defence and mitochondrial complex enzyme ac- tivities in brain. Conclusion: Present study suggests the protective role of statins against chronic fatigue induced behavioral, biochemical and mito- chondrial dysfunctions.
