这个“类”是什么意思?
多肽和蛋白质类激素(不可口服):促甲状腺激素释放激素,促甲状腺激素,促性腺激素、生长激素,催乳素,胰岛素,胰高血糖素,
氨基酸类衍生物(可口服):甲状腺激素、肾上腺素
脂质类激素:(可口服)性激素和孕激素
蛋白质类激素不能口服,因会被消化液中的蛋白酶分解(——这是原因)
这是我们老师说的哦!!希望对你有帮助
作者、斯坦福大学医学中心的梅斯勒(AnnaH.Messner)和同事解释,有多个研究曾检查了在扁桃体切除手术前使用类固醇类药的情况,但得到的结果不一。据他们在8月《耳鼻喉、头、颈外科文献》(ArchOtolaryngolHeadNeckSurg2004;130:917-921)上发表的论文说,他们对这种病人进行了一项最大的前瞻性、随机、双盲研究。
共219名9个月至12岁的参试者被随机分为或用地塞米松1mg/kg,最大剂量至50mg(n=106),或用安慰剂(n=113)。在药物组中,62人进行的扁桃体切除术采用的是电烧烙法,44人采用的是锐性分离。安慰剂两种方法分别为56人和57人。术后第一天,类固醇组医生评定的Wong-Baker可视模拟量表上的疼痛分平均为4.4,安慰剂组5.3(p<0.001);前组家长评估的疼痛分(p=0.002)和病儿自己评估的疼痛分((p=0.002))也明显更低。类固醇组有1.2次呕吐发作,安慰剂组2.1次(p=0.02),前组也更快地恢复了正常进食(=0.004)。另外,作者还发现,进行锐性分离的病人使用类固醇受益最大,医生和家长评估的疼痛分显著低于电烧烙组。
“我们的研究结果支持在进行扁桃体手术时以1mg/kg的剂量IV地塞米松”,研究者总结。
