Objective: In this study, the analgesic effect of gold injection aqua-acupuncture on CFA induced arthritis in rats was inverstigated. Furthermore, to determine the antinociceptive mechanism of gold injection aqua-acupuncture, naloxone and yohimbine were administrated intraperitoneally 15min prior to the gold injection aqua-acupuncture. Methods: The experimental groups were divided into 6 groups. Control group, NSI, AMI, AMI+SL : AMI+Nx, AMI+Yb. Thereafter we measured the chages of TFL between control and experimental groups. Results: 1. The tail flick latency induced by CFA was significantly increased on AMI as compared with the NSI group. 2. Effect of sodium aurothiomalate aqua-acupuncture in TFL on CFA was decreased after application of naloxone. The anti-nociceptive effect of AMI was completely antagonized by naloxone(an opioid receptor antagonist). 3. Effect of sodium aurothiomalate aqua-acupuncture in TFL on CFA was decreased after application of yohimbine. The anti-nociceptive effect of AMI was completely antagonized by yohimbine(${\alpha}2$-adrenoceptor antagonist). Conclusions: According to the results, gold injection aqua-acupuncture has significant analgesic effects on adjuvant induced arthritis in rats and the effect of anti-nociception was mediated by opiodergic system and ${\alpha}2$-adrenergic system.

The purpose of this study was to see the effect of anti inflammatory and analgesic action of the glucosamine hydrochloride(GA HCl) or taurine. Male Sprague Dawley rats(100~250g) and ICR mice(20 ~30g) were used. Experimental groups were divided into seven groups, one control group given as saline and six groups given as oral administration of GA HCl or taurine; GA HCl 250mg/kg, b.w group, taurine 250mg/kg, b.w group, GA HCl 250mg/kg, b.w＋taurine 250mg/kg, b.w group, GA HCl 500mg/kg, b.w group, taurine 500mg/kg, b.w group, GA HCl 500mg/kg, b.w＋taurine 500mg/kg, b.w group. Carrageenan induced edema test were shown to be significantly inhibited in the GA HCl 250mg/kg group and taurine 250mg/kg group compared to the control group, but the GA HCl 500mg/kg＋taurine 500mg/kg group were significantly inhibited than the control group. Capillary permeability test were shown to be sig nificantly inhibited in the taurine 500mg/kg group, but the GA HCl 500mg/kg＋taurine 500mg/kg group were significantly inhibited than the control group. Leucocyte emigration test were shown to be significantly inhibited in the GA HCl 250mg/kg＋ taurine 250mg/kg group and GA HCl 500mg/kg＋taurine 500mg/kg group compared to the control group. Acetic acid, Phenyl p benzoquinone writhing syndrome were shown to be significantly inhibited in the GA HCl 500mg/kg＋taurine 500mg/kg group compared to the control group. Inhibitory action against COX 1 and COX 2 were not significantly inhibited in the experimental group. These results suggest that the combined administration of the GA HCl and taurine have potential action in anti inflammatory and analgesic action.

New herbal formula (NHF) is the ethanol extract mixture of Puerariae radix, Artemisia capillaries and Perilla frutescens. We have Investigated the effects on anti-inflammation by NHF and attempted acetic acid induced writhing to verify the analgesic effect. Macrophages and chondrocytes were obtained from mouse and rabbit. Inflammation was induced bγ interleukin-1, tumor necrosis $factor-{\alpha}$, $interferon-{\gamma}$, and lipopolysaccharide. NHF showed strong inhibitory efficacy against cytokine-induced proteoglycan degradation, $PGE_2$ production, NO production, and MMP-9 expression in rabbit articular chondrocyte. In the writhing test, NHF exhibited a dose-dependent inhibition of writhing. Futhermore, NHF increased the activity of SOD. NHF have anti-inflammatory and analgesic activities, and could be a good herbal medicine candidate for curing of osteoarthritis.

Objectives : We observed the possibilities that blue honeysuckle has favorable analgesic or refinement effects on the Primary dysmenorrhea (PD) in rats. Methods : Estradiol benzoate and oxytocin were used to induce the PD rat model. And Blue honeysuckle concentration lyophilized powders (BH) 500, 250 and 125 mg/kg and 500 mg/kg of Lonicerae Flos aqueous extract lyophilized powders (LF) were orally administered, once a day for 10 days at 30 min after each estradiol benzoate treatment. Then the changes on the body weights and gains during experimental periods, abdominal writhing response for analgesic activities, uterine weights, uterus lipid peroxidation, antioxidant defense system - glutathione contents, superoxide dismutase and catalase activities, NF-κB and COX-2 mRNA expressions were monitored with uterus histopathology including immunohistochemistry for tumor necrosis factor (TNF)-α and inducible nitric oxide synthase (iNOS).. Results : Inflammatory and oxidative stress mediated PD signs were favorably and dose-dependently inhibited by 10 days continuous oral administration of three different dosages of BH - 500, 250 and 125 mg/kg as comparable to those of indomethacin(IND) 5 mg/kg treated rats in BH 500 mg/kg administered PD rats, and similar to those of LF 500 mg/kg in BH 125 mg/kg, at least in a condition of the present PD rat model. Conclusions : The results suggest that BH has favorable analgesic and refinement activities on the estradiol benzoate and oxytocin treatment-induced PD signs through anti-inflammatory and antioxidative potentials.

Background: Previous studies have suggested synergistic analgesic drug interactions between NSAIDs and opioids in neuropathic and inflammatory pain models. The aim of this study was to investigate the analgesic drug interaction between intraperitoneal (IP) ketorolac and morphine in radiant thermal stimulation rat. Methods: Initially, we assessed the withdrawal latency time of the hindpaw to radiant thermal stimulation every 15 min for 1 hour and every 30 min for next 1 hour after IP normal saline 5 ml (control group). The latency time was changed into percent maximal possible effect (%MPE). Next, IP dose response curves were established for the %MPE of morphine (0.3, 1, 3, 10 mg/kg) and ketorolac (3, 10, 30 mg/kg) to obtain the $ED_{50}$ for each agent. And we confirmed that the IP morphine effect was induced by opioid receptor through IP morphine followed by IP naloxone. At last, we injected three doses of IP ketorolac (3, 10, 30 mg/kg) mixed with one dose of morphine (2 mg/kg) for fixed dose analysis. Results: IP morphine delayed the paw withdrawal latency time dose dependently, but not ketorolac. $ED_{50}$ of IP morphine was 2.1 mg/kg. And the IP morphine effect was reversed to control level by IP naloxone. IP ketorolac + morphine combination showed no further additional effects on paw withdrawal latency time over morphine only group. Conclusions: IP ketorolac did not produce antinociceptive effect during radiant thermal stimulation. There was neither additional nor synergistic analgesic interaction between IP morphine and ketorolac in thermal stimulation rat.

Background: This study assessed the postoperative analgesic efficacy and safety of the quadratus lumborum block (QLB) in pediatric patients. Methods: Electronic databases were searched for studies comparing the QLB to conventional analgesic techniques in pediatric patients. The primary outcome was the need for rescue analgesia 12 and 24 hours after surgery. Secondary outcomes covered the Face-Legs-Activity-Cry-Consolability Scale (FLACC) scores at various time points; parental satisfaction; time to the first rescue analgesia; hospitalization time; block execution time; block failure rates, and adverse events. Results: Sixteen randomized controlled trials were analyzed involving 1,061 patients. The QLB significantly reduced the need for rescue analgesia both at 12 and 24 hours after surgery (12 hours, relative risk [RR]: 0.45; 95% confidence interval [CI]: 0.01, 0.88; 24 hours, RR: 0.51; 95% CI: 0.31, 0.70). In case of 24 hours after surgery, type 1 QLB significantly reduced the need for rescue analgesia (RR: 0.56; 95% CI: 0.36, 0.76). The QLB also exhibited lower FLACC scores at 1 hour (standardized mean difference [SMD]: -0.87; 95% CI: -1.56, -0.18) and 6 hours (SMD: -1.27; 95% CI: -2.33, -0.21) following surgery when compared to non-QLB. Among QLBs, type 2 QLB significantly extended the time until the first rescue analgesia (SMD: 1.25; 95% CI: 0.84, 1.67). No significant differences were observed in terms of parental satisfaction, hospitalization time, block execution time, block failure, or adverse events between QLB and non-QLB groups. Conclusions: The QLB provides non-inferior analgesic efficacy and safety to conventional methods in pediatric patients.

The behavioral effects of propranolol (60mg/kg) and metoprolol (100mg/kg) each alone and coadministered orally with cinnarizine (100mg/kg) were investigated and compared with each of betablockers alone treated group in rodents. Propranolol showed depressive effects through locomotor activity, conditioned avoidance response, rota-rod test, traction test, and analgesic effect in mice. When combined with cinnarizine and propranolol, the behavioral depressive effect of propranolol was reduced comparing with propranolol alone treated group. However, metoprolol alone or combined with cinnarizine didn't showed any behavioral depressive effect so much as propranolol.
