Antiinflammatory and analgesic effect of herbal cocktail Hongbaekjeong via inhibition of proinflammatory cytokines and prostaglandin E2 release

Though Hongbaekjeong(HBJ),a hebal mixture of three medicinal plants,has been traditionally used for arthritis and muscular pain,its scientific evidence still remains unclear.Thus,in the present study,analgesic and anti-inflammatory mechanism of HBJ was evaluated in vitro and in vivo.HBJ significantly reduced NO production and prostaglandin E2(PGE2)release and also attenuated the expression of cyclooxygenase 2(COX-2)in lipopolysaccharides(LPS)and interferon(IFN)-c treated RAW 264.7 cells.Furthermore,HBJ abrogated the production of proinflammatory cytokines such as interleukin(IL)1b,IL-6,IL-8 and monocyte chemoattractant protein-1(MCP-1)in LPS and IFN-c treated RAW 264.7 cells.In addition,HBJ significantly decreased the number of writhing syndrome induced by acetic acid,and also increased latency in hot-plate method and tail flick test in mice.Consistently,HBJ significantly reduced the edema volume in the hind paw of the rats with arthritis induced by Freund’s complete adjuvant(FCA)compared to untreated control.Collectively,our findings demonstrate the antiinflammatory and analgesic potential of HBJ via inhibition of proinflammatory cytokines and PGE2 release for treatment of arthritis and muscular pain.

复方威茯急性毒性实验及抗炎镇痛作用观察

研究复方威茯的急性毒性作用,并观察其抗炎镇痛作用。以最大给药量方法进行急性毒性实验,观察小鼠一般情况等,14 d后处死解剖,观察小鼠主要脏器组织病变情况。以二甲苯致小鼠耳廓肿胀、醋酸致小鼠腹腔毛细血管通透性增加,实验观察复方威茯抗炎作用。以冰醋酸致小鼠扭体、热板致小鼠疼痛探讨复方威茯镇痛作用。结果在急性毒性实验中,未见小鼠有中毒症状或死亡,外观表现未见异常,解剖后未见脏器异常;复方威茯可明显抑制二甲苯所致小鼠耳廓肿胀度和醋酸致腹腔毛细血管通透性的增高(P0.05或P0.01),可明显减少醋酸致小鼠扭体反应次数(P0.01),可提高热板致小鼠疼痛的痛阈值(P0.05或P0.01)。说明复方威茯无明显的急性毒性作用,有明显的抗炎镇痛作用。     

鸡屎藤苷酸与鸡屎藤苷酸甲酯二聚体对小鼠的镇痛作用研究

背景：鸡屎藤具有明确的镇痛作用,鸡屎藤苷酸与鸡屎藤苷酸甲酯是（）。目的：考察鸡屎藤苷酸（Paederosidic Acid）与鸡屎藤苷酸甲酯（Paederosidic Acid Methyl Ester）二聚体不同浓度下的镇痛作用,并初步探讨其作用机制。方法：采用ICR小鼠,以小鼠福尔马林实验进行镇痛作用评价,以热板实验确定镇痛机制。结果：福尔马林实验结果显示,鸡屎藤苷酸与鸡屎藤苷酸甲酯二聚体有镇痛效果。利用热板实验,确定鸡屎藤苷酸与鸡屎藤苷酸甲酯二聚体为中枢镇痛作用,40mg/kg是镇痛的最大效应浓度。结论：鸡屎藤苷酸与鸡屎藤苷酸甲酯二聚体有中枢镇痛作用。     

Synthesis ofO 1.5-(β-D-galactopyranosyl) [DMet2, Hyp5] enkephalin amide,a new highly potent analgesic enkephalin-related glycosyl peptide

Summary A new series of O-glycosyl enkephalins has been prepared, following a convergent strategy, with high chemical yields. The galactosyl analogue,O ^1.5-(-D-galactopyranosyl) [DMet², Hyp⁵] enkephalin amide proved to be one of the most potent in vivo opioid agonists synthesized up to now.     

天南星及炮制品镇痛作用与毒性相关性的实验观察

目的：实验观察天南星及炮制品镇痛与毒性的相关性,寻求镇痛成分提取的可能性。方法：热板法比较镇痛效果,致死时间比较毒性。结果：给药0.5h痛阈提高百分率,生药及民制品均在85％以上,生品1.5h后便有20％死亡,用民制品次日死亡,其它制品痛阈提高百分率在70％以下,3d后死亡。结论：某毒性成分具有镇痛作用,水溶性差,提取可能。

Drainage after total thyroidectomy or lobectomy for benign thyroidal disorders

Objective： This prospective randomized clinical trial was conducted to evaluate the necessity of drainage after total thyroidectomy or lobectomy for benign thyroidal disorders. Methods： A total of 116 patients who underwent total thyroidectomy or lobectomy for benign thyroidal disorders were randomly allocated to be drained or not. Operative and postoperative outcomes including operating time, postoperative pain assessed by visual analogue scale （VAS）, total amount of intramuscular analgesic administration, hospital stay, complications, necessity for re-operation and satisfaction of patients were all assessed. Results： The mean operating time was similar between two groups （the drained and non-drained groups）. The mean VAS score was found to be significantly low in the non-drained group patients in postoperative day （POD） 0 and POD 1. The mean amount of intramuscular analgesic requirement was significantly less in the non-drained group. One case of hematoma, two cases ofseroma and three cases of transient hypoparathyroidism occurred in the non-drained group, whereas one case of hematoma, two cases of seroma, two cases of wound infections and two cases of transient hypoparathyroidism occurred in the drained group. No patient needed re-operation for any complication. The mean hospital stay was significantly shorter and the satisfaction of patients was superior in the non-drained group. Conclusion： These findings suggest that postoperative complications cannot be prevented by using drains after total thyroidectomy or lobectomy for benign thyroid disorders. Furthermore, the use of drains may increase postoperative pain and the analgesic requirement, and prolong the hospital stay. In the light of these findings, the routine use of drains might not be necessary after thyroid surgery for benign disorders.     

烫伤宁镇痛抗炎作用的实验研究

探讨烫伤宁是否具有镇痛抗炎作用,为其冶疗烫伤提供药效学依据。采用小鼠扭体、激光致痛等模型观察烫伤宁的镇痛效果,用小鼠耳肿法观察烫伤宁外用对急性渗出性炎症的影响。结果为烫伤宁无论灌胃或腹腔注射原药及稀释２～８倍（按０２ｍＬ／１０ｇ体重给药）,均显著抑制小鼠扭体反应;大鼠浅Ⅱ°烫伤创面外涂烫伤宁原药及稀释４、１６倍药液１ｍＬ,可显著提高激光致痛的痛阈。正常耳廓涂药不能对抗二甲苯所致耳肿胀。
