Cancer therapy with phytochemicals: evidence from clinical studies
Cancer is still one of the major causes of mortality in both developing and developed countries. At this time, in spite of intensive interventions, a large number of patients have poor prognosis. Therefore, the effort for finding new anticancer agents with better efficacy and lesser side effects has continued. According to the traditional recommendations and experimental studies, numerous medic...
متن کاملStress-induced analgesia.
For over 30 years, scientists have been investigating the phenomenon of pain suppression upon exposure to unconditioned or conditioned stressful stimuli, commonly known as stress-induced analgesia. These studies have revealed that individual sensitivity to stress-induced analgesia can vary greatly and that this sensitivity is coupled to many different phenotypes including the degree of opioid s...
متن کاملEffect of transient inactivation of rostral ventromedial medulla on swim stress induced analgesia in formalin test in rats
Introduction: Despite significant progress in understanding pain control mechanism, there are numerous questions about central nervous mechanisms underlying stress-induced analgesia. The rostral ventromedial medulla (RVM) in the brainstem integrates a variety of functions, including pain modulation and pain perception. In the present study, we investigated the effect of temporary inactivatio...
متن کاملبررسی اثر ضددرد استرس به تنهایی یا در حضور آگونیست و آنتاگونیست گیرنده‌های CCK در درد نوروپاتیک به روش صفحه داغ در موش سوری
Introduction: Recent studies have shown that cold water swimming stress (CWSS) produces analgesia. Although exact mechanism of the analgesia is until unclear, it may attributed to CCK receptors. On the other hand, the effectiveness of analgesic drugs for treatment of neuropathic pain is limited. In the present study, the effects of CCK receptor agonist caerulein and antagonist proglumide , both...
متن کاملPermanent lesion in rostral ventromedial medulla potentiates swim stress-induced analgesia in formalin test
Objective(s): There are many reports about the role of rostral ventromedial medulla (RVM) in modulating stress-induced analgesia (SIA). In the previous study we demonstrated that temporal inactivation of RVM by lidocaine potentiated stress-induced analgesia. In this study, we investigated the effect of permanent lesion of the RVM on SIA by using formalin test as a model of acute inflammatory pa...
