To observe the effect of electroacupuncture (EA) on pain behavior and expression of µ-opioid receptor (MOR) and Rab5 (an important protein molecule for internalization of MOR) in the locus coeruleus (LC) region in bone cancer pain (BCP) rats with morphine tolerance (MT), so as to More than half of patients receiving prescription medicine for cancer pain have been reported to experience inadequate pain relief or breakthrough pain. Buccal administration can deliver lipophilic opioids rapidly to the systemic circulation through the buccal mucosa, limiting gastrointestinal
OBJECTIVE
Not all bone cancer pain can be effectively treated with current therapies. In the present study, the effects of ip administration of alpha-2 agonists (dexmedetomidine and clonidine), N-methyl-D-aspartate (NMDA) antagonists (MK-801 and ketamine), an N-acetylaspartylglutamate peptidase
Bone is a common metastatic site for prostate and breast cancer, and bone cancer is usually associated with severe pain. Traditional treatments for cancer pain can sometimes be ineffective or associated with side effects. Thus an increasing number of patients seek alternative therapies. In this
OBJECTIVE
To explore the effects of cannabinoid 2 receptor (CB2) in the development of bone cancer pain in mice.
METHODS
A total of 84 mice (C3H/HeJ) were randomly divided into 4 groups:tumor group (Group T, n = 30), medication administration group (Group J, n = 12), vehicle group (Group D, n = 12)
BACKGROUND
Previous studies have demonstrated that chemokine CXCL12 and its receptor CXCR4 are critical for pain sensitization, but the mechanisms involved are not clear. In this study, we investigated the specific cellular mechanisms of CXCL12/CXCR4 chemokine signaling in the development and
BACKGROUND
Oral transmucosal fentanyl citrate lozenges (lollipops) are indicated for the oral management of breakthrough cancer pain. When abused, these sucrose-containing lozenges can cause rampant dental caries.
METHODS
The authors examined a 19-year-old man whose dentist referred him because of
OBJECTIVE
To study the effect of sophoridine against bone cancer pain in bone cancer pain model rats induced by W256 tumor cells and its mechanism.
METHODS
The rat model of bone cancer pain was reproduced by injecting W256 tumor cells into the rat marrow cavity. Ten days after the model
Pain is one of the most common and distressing symptoms suffered by patients with progression of cancer. Using a rat model of bone cancer, recent findings suggest that proteinase-activated receptor 2 (PAR2) signaling pathways contribute to neuropathic pain and blocking PAR2 amplifies antinociceptive
Treating bone cancer pain poses a major clinical challenge, and the mechanisms underlying bone cancer pain remain elusive. EphrinB-EphB receptor signaling may contribute to bone cancer pain through N-methyl-d-aspartate receptor neuronal mechanisms. Here, we report that ephrinB-EphB signaling may
Chronic pain resulting from metastasis into skeleton of certain neoplastic diseases remains poorly understood and relatively resistant to analgesic treatment. Opioids are the principal axis in drug therapy for this type of pain, especially at the end stage of cancer. Our aim was to examine whether,
To observe the effect of bone-edge electroacupuncture (EA) intervention on mechanical pain threshold (PT) and expression of G protein-coupled receptor kinase (GRK5), β-arrestin 2, total and phosphorylated PKC alpha (p-PKCα) proteins in the locus coeruleus (LC) of rats with bone cancer OBJECTIVE
To investigate the possibility of establishing rat model of bone cancer pain using cancer cells cultured in vitro or by ascites passaging and verify the reliability of this method.
METHODS
Syngeneic SD rat carcinoma cells of the line Walker 256 were cultured in vitro and inoculated into
Objective: To evaluate the analgesic effects of cinobufagin (CBG) on cancer-induced bone pain in rat and study the role of the muscarinic receptor M4 subtype (M4 mAChR) in its involvement. Methods: A total of 100 Female Sprague-Dawley rats were randomly divided into 5 groups
OBJECTIVE
Pleural phenol was used successfully to alleviate terminal pain associated with metastatic esophageal cancer in a 43-year-old man.
METHODS
The patient first was given 20 ml 0.5% bupivacaine for diagnostic purposes through an interpleural catheter to control a severe aching pain throughout
