Neuropathic pain remains one of the most difficult forms of pain to *** wide variety of drugs currently used in its treatment often does not provide adequate pain *** a clinical point of view,an interaction between of the melanocortin and opioid systems is interesting because administration of melanocortin receptor antagonists may increase the sensitivity for opioids,thus improving the efficacy to adverse effects ratio of opioids in neuropathic pain *** research is needed to further elucidate the mechanisms underlying these effects of melanocortin and to see whether the melanocortin MC4 receptor can be a target in the challenge to alleviate neuropathic pain.
目的化学刺激白色脂肪组织(WAT)引起交感神经兴奋和血压升高,称之为脂肪传入反射(adipose afferent reflex,AAR)。肥胖大鼠AAR增强,在肥胖高血压大鼠的交感神经激活中起重要作用。下丘脑室旁核(PVN)是AAR调节和整合的重要中枢核团。本研究的目的是探讨PVN中黑皮质素受体(MCR)在调节AAR中的作用和机制.方法实验采用350~400 g SD大鼠,麻醉状态下记录肾交感神经活动(RSNA)和平均动脉压(MAP)。在右侧腹股沟WAT
