Effect of electroacupuncture on E-prostanoid 2 expression in the spinal cord in rats with neuropathic pain.

Objective: To observe the effect of electroacupuncture (EA) treatment on the expression of E-prostanoid 2 (EP2) in the spinal cord using a rat model of neuropathic pain, and to examine the effect of different acupuncture prescriptions.

Methods: Rats were randomly divided into six groups: a normal group, model group, sham group, EA 1 group (distal-proximal acupoints), EA 2 group (proximal acupoints), and EA 3 group (distal acupoints). Rats in the EA groups were treated for 20 min, once daily for 7 days.

Effects of electroacupuncture intervention on expression of cyclooxygenase 2 and microglia in spinal cord in rat model of neuropathic pain.

Objective: To investigate the effect of electroacupuncture (EA) treatment on the expression of cyclooxygenase (COX) 2 and microglia in spinal cord by using rat model of neuropathic pain, and to probe into the relationship between COX 2 and microglia.

Methods: The rats were randomly divided into 6 groups, including normal control group, model group, sham group, EA 1 group (distant acupoints + local acupoints), EA 2 group (local acupoints), and EA 3 group (distant acupoints). Thermal withdrawal latencies were evaluated at 1 day preoperatively and 3, 5 and 7 days postoperatively.

Behavioral changes over time in post-traumatic stress disorder: Insights from a rat model of single prolonged stress.

Post-traumatic stress disorder (PTSD) is manifested as a persistent mental and emotional condition after potentially life-threatening events. Different animal models of PTSD have been developed for neuro-pathophysiology and pharmacological evaluations. A single prolonged stress (SPS) induced animal model has demonstrated to result in specific neuro-endocrinological dysregulation, and behavior abnormalities observed in PTSD.

XiangshaLiujunzi decoction alleviates the symptoms of functional dyspepsia by regulating brain-gut axis and production of neuropeptides.

Background: Chinese medicine xiangshaliujunzi decoction (XSLJZD) plays a key role in treating functional dyspepsia (FD), a common clinical gastrointestinal disorder. However, the mechanism of this disease is unclear. Brain-gut axis regulates food intake behaviour, and this regulatory mechanism is mediated by neuropeptides.

Effects of Ca(OH)2 assisted aluminum sulfate coagulation on the removal of humic acid and the formation potentials of tri-halomethanes and haloacetic acids in chlorination.

The effects of addition of calcium hydroxide on aluminum sulphate (or alum) coagulation for removal of natural organic matter (NOM) and its subsequent effect on the formation potentials of two major types of regulated disinfection byproducts (DBPs), haloacetic acids (HAAs) and trihalomethanes (THMs), have been examined. The results revealed several noteworthy phenomena. At the optimal coagulation pH (i.
