(1) BACKGROUND: Chronic pain, including hyperalgesia and algesthesia paresthesia, is pathological phenomenons making the patients felt unendurable and lacking of clinical treatments.

(2) Acute hyperalgesia is detected at the remaining part of the tail as well as hindpaw.

(3) Conclusion Pentazocine can prevent postoperative hyperalgesia induced by remifentanilbased anesthesia.

(4) Many researchers, therefore, have amelioration of hyperalgesia and allodynia foremost in their minds as they hunt for new analgesics.

(5) A case with trauma history suffered from hyperalgesia , swelling and stiffness over bilateral upper extremities, numerous medications treatments were unsuccessful.

(6) To improve this hypothesis we must make sure that the expression change of GDNF in DRGs is related to hyperalgesia.

(7) Conclusions:These studies show that ASMT can significantly reduce the severity and shorten the duration of pain and hyperalgesia caused by lumbar IVF inflammation.

(8) This study aimed at investigating in details the spatial characteristics of muscular hyperalgesia after development of delayed onset muscle soreness (DOMS) in the trapezius muscle.

(9) Conclusion NO is involved in nociceptive transmission at the spinal cord following nerve injury and it may result in hyperalgesia and allodynia.

(10) On the one hand, after nerve compression, the afferent neurons increase the release of substance P, Glutanic acid and other pain transmitters, which will induce hyperalgesia .

(11) The technique of high density pressure pain topographical mappings can be helpful in characterizing muscle hyperalgesia and its heterogeneity.

(12) Background and aims: Patients with functional dyspepsia who have hypersensitivity to gastric distension have more prevalent pain, suggesting the presence of hyperalgesia.

(13) Peripheral tissue and nerve injury lead to chronic pain symptoms, including spontaneous pain, allodynia and hyperalgesia.

(14) Objective To evaluate the role of protein kinase C(PKC) in the thermal hyperalgesia evoked by local injection of endothelin-1(ET-1).

(15) However, these studies have been performed using cutaneous models of hyperalgesia.

(16) However, significant correlation was found with the extent of adaptation and hyperalgesia on the unaffected hand.

(17) The behavior results showed that blocking peripheral 5-HT_(2A)receptors inhibited the thermal hyperalgesia in inflammatory and neuropathic pain.

(18) The peripheral nerve injury caused by some pathological factors results in pathological chronic pain, such as hyperalgesia, allodynia[Sentencedict], and spontaneous pain ect.

(19) Results Sprout number of DRG in experimental group rats decreased obviously and the symptom of hyperalgesia was improved as compared to control rats.

(20) Objective To observe the injuries to the dorsal root ganglion(DRG) derived by auto transplantation of nucleus pulposus and find out the relationship between the injuries and the hyperalgesia.

(21) Inflammation and trauma lead to enhanced pain sensitivity ( hyperalgesia ), which is in part due to altered sensory processing in the spinal cord.
