以12只新西兰白兔为研究对象,造模后随机分为2组,每组6只.A组为对照组,损伤后自然恢复;B组为特异针刺组,损伤后即刻、第1d～5d在损伤部位施以特异针刺治疗,1次/d,每次1.5min～2min.于损伤前,损伤后即刻,损伤后第1、2、3、6天采血,用酶联免疫法测试不同时间血清前列腺素E2(PGE2)、五羟色胺(5-HT)和组胺(HA)浓度.结果表明,与对照组相比,在损伤后第1天特异针刺组血清PGE2显著性的降低(P<0.05),血清5-HT显著性的降低(P<0.01),血清HA的值没有显著性变化(P>0.05);在损伤后第2天,特异针刺组血清PGE2、5-HT和HA值均显著性的降低(P<0.05);在损伤后第3天特异针刺组血清5-HT和HA的浓度均显著性的降低(P<0.05),血清PGE2的值无明显差异(P>0.05);在损伤第6天,两组测试指标无显著性差异(P>0.05).由此而见,特异针刺疗法可有效降低兔急性骨骼肌损伤后的血清PGE2、5-HT和HA等疼痛因子的浓度,减轻损伤后疼痛程度.  相似文献

Insulin resistance and the resultant hyperinsulinemia exacerbate the reproductive abnormalities of Polycystic Ovarian Syndrome by increasing ovarian androgen productions and decreasing serum sex hormone binding globulin. The present study was conducted to estimate serum insulin and testosterone level in 44 PCOS cases and 32 control patients. Simultaneously the role of metformin (an insulin sensitizing agent) in modulating insulin resistance and serum androgen level was also analyzed. A significant rise in serum insulin and testosterone (P < 0.001) was observed in cases in comparison to control. Fasting Plasma Glucose to insulin ratio, a marker of insulin resistance revealed a significant fall in PCOS group. Follow up of cases with metformin for 3 months revealed a significant fall in serum insulin (P < 0.05) with improvement in insulin resistance along with a nonsignificant fall in testosterone level. Serum insulin registered a significant positive correlation (P < 0.05) with serum testosterone revealing its etiological association. Thus administration of drugs ameliorating insulin levels is expected to provide new therapeutic modality for PCOS.  相似文献
