摘 要 目的:探讨苗药了哥王炮制前后抗小鼠免疫性炎症的“量-效-毒”关系。方法:将小鼠分成空白组、模型组、了哥王生品醇
提物1~6组、了哥王“汗渍法”炮制品醇提物1~6组(以下分别简称为“生品1~6组”“炮制品1~6组”,剂量均分别为0.13、0.20、
0.26、0.52、1.04、2.6 g/kg)和阳性组(环磷酰胺,36.4 mg/kg),每组 10 只。除空白组外,其余各组小鼠均以 1% 2,4-二硝基氟苯-丙
酮-麻油混合溶液复制迟发型超敏反应模型。造模后,空白组和模型组小鼠均灌胃等容1.0%羧甲基纤维素钠溶液,各给药组小鼠
灌胃相应药液20 mL/kg,每日1次,连续5 d。末次给药后,记录各组小鼠耳肿胀度,并计算生品及炮制品的肿胀抑制率、半数有效
剂量(ED50 )及其95%置信区间(CI);称定小鼠心、肝、脾、肺、肾的质量,并计算各脏器指数;采用酶联免疫吸附测定法、改良化学氧
化法分别检测小鼠血清中炎症因子[肿瘤坏死因子α(TNF-α)、白细胞介素10(IL-10)]和肝肾功能指标[丙氨酸转氨酶(ALT)、天冬
氨酸转氨酶(AST)、总胆红素(TBIL)、尿素氮(BUN)、血肌酐(CREA)]水平。结果:与空白组比较,模型组小鼠耳肿胀度显著升高
(P<0.05);与模型组比较,了哥王生药及炮制品醇提物各剂量组小鼠耳肿胀度均显著降低(P<0.05),其肿胀抑制率均有随剂量
增加而升高的趋势,两者抗小鼠迟发型超敏反应耳肿胀的 ED50及 95%CI 分别为 0.239 6(0.129 0,0.445 2)g/kg、0.147 3(0.076 8,
0.282 7)g/kg。与空白组比较,模型组小鼠肝指数、血清TNF-α水平均显著升高,肺指数、血清IL-10水平均显著降低(P<0.05);与
模型组比较,不同给药组小鼠肝指数(阳性组、生品 3 组和炮制品 1~6 组)、血清 TNF-α水平(阳性组、生品 1~3 组及炮制品 1~4
组)均显著降低,肺指数(阳性组、生品3~6组及炮制品3~6组)、血清IL-10水平(生品1、2、4、5组以及炮制品2~6组)以及ALT、
AST、BUN、CREA水平(生品4~6组)和TBIL水平(生品3~6组)均显著升高(P<0.05)。结论:了哥王生品醇提物具有一定的抗
免疫炎症活性,且对小鼠具有肝肾毒性,呈一定的“量-效-毒”关系;炮制品醇提物也具有一定的抗免疫炎症活性,但肝肾毒性弱于
生品。“汗渍法”具有“存效减毒”的效果。

ABSTRACT OBJECTIVE:To investigate the“dose-effect-toxicity”correlation of Miao medicine Wikstroemia indica before and
after processed on anti-immnue inflammation of mice. METHODS:Mice were divided into blank group,model group,ethanol
extract of W. indica raw product groups 1-6,ethanol extract of W. indica processed product by“sweat soaking method”groups 1-6
(hereinafter called“raw groups 1-6”“processed groups 1-6”for short,drug dosage were 0.13,0.20,0.26,0.52,1.04,2.6 g/kg),
positive group(cyclophosphamide,36.4 mg/kg),with 10 mice in each group. Except for blank group,other groups were given
1% 2,4-dinitrofluorobenzene-acetone-sesame oil mixed solution to induce delayed type hypersensitivity model. After modeling,
blank group and model group were given constant volume of 1.0% CMC-Na solution intragastrically,and administration groups
were given relevant medicine 20 mL/kg intragastrically,once
