Studies on Reproduction in Rats with Meclofenamate Sodium, a Nonsteroidal Anti-inflammatory Agent

Studies on Reproduction in Rats with Meclofenamate Sodium, aNonsteroidal Anti-inflammatory Agent. PETRERE, J. A., HUMPHREY,R. R., ANDERSON, J. A., FITZGERALD, J. E., AND DE LA IGLESIA,F. A. (1985). Fundam. Appl. Toxicol. 5, 665–671. Reproductionand teratology studies were performed in rats given meclofenamatesodium, a nonsteroidal anti-inflammatory agent. Dosages of 0,3, 6, and 9 mg/kg were administered orally as dietary admixturesin the Fertility and Perinatal-Postnatal studies. In the Teratologystudy, dosages of 10, 12, 15, and 20 mg/kg were administeredby intragastric intubation. In the Male-Fertility study no adverseeffects on fertility or litter and offspring parameters wereobserved in two generations. In the Female-Fertility and Perinatal-Postnatalstudies, maternal toxicity (death associated with intestinalulceration and adhesions) was particularly evident during lactation.Prolonged gestation periods, decreased weanling weights, andincreased weanling mortality were evident at dosages of 6 and9 mg/kg. Increased postimplantation loss occurred at 6 and 9mg/kg in the Term Sacrifice subgroup of the Female-Fertilitystudy. Fertility rates were unaffected and all other litterand offspring parameters of the F₁ and F₂ generations appearednormal. In the Teratology study no adverse effects on embryonicor fetal development were evident at maternally toxic dosagesup to 20 mg/kg. © 1985 Society of Texicology.     

慢性乙肝患者肝组织纤维化程度与HBV-DNA复制水平的相关性研究

目的:探讨HBV-DNA复制水平与肝纤维化之间的相关性。方法:对210例慢性乙型肝炎患者进行HBV-DNA和肝纤维化血清学标志透明质酸(HA)、层粘蛋白(LN)、III型前胶原(PCIII)、IV型胶原(IV-C)进行定量检测。应用SPSS10.0统计软件对结果数据进行分析处理。结果:随慢性乙肝临床类型的加重,肝纤维化血清学标志逐渐升高(P<0.01),而肝纤维化血清学标志与HBV复制水平呈正相关(P<0.05);结论:HBV复制水平与肝纤维化之间呈正相关。     

秦艽醇提取物抗炎镇痛作用的实验研究

目的:研究秦艽醇提取物的抗炎及镇痛作用。方法:采用二甲苯致小鼠耳廓肿胀,角叉菜胶致大鼠足趾肿胀及冰醋酸致小鼠扭体反应,观察秦艽醇提物的抗炎及镇痛作用。结果:秦艽醇提物能降低二甲苯炎症模型小鼠的耳廓肿胀度(P<0.01),对角叉菜胶模型大鼠的急性炎症有一定的抑制作用,从第3小时起足趾容积和肿胀度与模型组比较具有统计学意义(P<0.05),秦艽醇提物还能提高小鼠的痛阈,减少冰醋酸致小鼠扭体次数,与模型组比较具有统计学意义(P<0.05)。结论:秦艽醇提物对二甲苯及角叉菜胶所致的炎症具有一定的抑制作用,同时具有明显的镇痛作用。
