Abstract Title:
Resveratrol and quercetin attenuate depressive-like behavior and restore impaired contractility of vas deferens in chronic stress-exposed rats: involvement of oxidative stress and inflammation.
Abstract:
Chronic stress is associated with male sexual problems including ejaculatory dysfunctions. The aim of this study was to determine whether resveratrol (RS) or quercetin (QE) has protective effects on vas deferens (VD) contractility in the unpredictable chronic mild stress (UCMS) rat model of depression. Animals were separated into six groups: control, control + RS and control + QE, stress, stress + RS, and stress + QE. Stress groups were subjected to UCMS procedure for 5 weeks. Animals in treatment groups were injected intraperitoneally with RS (20 mg/kg) or QE (30 mg/kg) for 5 weeks during UCMS period. UCMS caused depressive-like behaviors and enhanced systemic levels of corticosterone. The nerve-evoked contractile responses of VD significantly impaired and, noradrenaline- and ATP-induced contractile responses of VD significantly increased in stressed rats. UCMS exposure also markedly enhanced oxidative stress and inflammationin VD tissues. Treatment with RS or QE significantly ameliorated all the aforementioned parameters. The current study demonstrated that RS or QE protected against chronic stress-induced VD dysfunction by their antioxidant and anti-inflammatory effects on VD, suggesting that oxidative stress and inflammation may be synergistic parts in the development of VD dysfunction associated with chronic stress-induced depression.
