摘要: 目的:探究1-庚基-3-甲基咪唑氯盐(C7[MIM]Cl)对小鼠的亚急性毒性。方法:根据C7[MIM]Cl对小鼠的半数致死剂量(LD50)119.00 mg/kg,将24只SPF级昆明小鼠随机分为对照组,低(1/50 LD50,2.38 mg/kg)、中(1/20 LD50,5.95 mg/kg)和高(1/10 LD50,11.9 mg/kg)剂量C7[MIM]Cl染毒组,每组6只,每天灌胃1次,连续灌胃28 d,对照组灌胃给予等体积的生理盐水。记录小鼠摄食量和体质量变化情况,实验结束取小鼠心、肝、脾、肺、肾和卵巢,称取脏器质量并计算脏器系数,检测血清生化指标,并采用HE染色观察小鼠各脏器的病理变化。结果:与对照组比较,5.95 mg/kg C7[MIM]Cl染毒组小鼠饲料消耗量降低(P=0.05);血清生化指标表明2.38 mg/kg C7[MIM]Cl染毒组小鼠血清中谷丙转氨酶活性显著上升(P=0.049),而5.95 mg/kg组小鼠血清总胆红素、血尿素、尿酸和总胆固醇以及11.9 mg/kg组小鼠血糖水平显著下降(P<0.05);组织切片观察结果显示不同剂量C7[MIM]Cl亚急性染毒对小鼠的肝、脾、肺、肾以及卵巢均有一定程度的损伤,其中肝脏和肾脏损伤更为明显。结论:C7[MIM]Cl亚急性染毒可引起小鼠肝脏和肾脏的功能性损伤。

Abstract: OBJECTIVE:To investigate sub-acute toxicity of the ionic liquid,1-heptyl-3-methy- limidazolium chloride,(C7[MIM]Cl) in mice. METHODS:According to the median lethal dose (LD50) of C7[MIM]Cl to mice as 119.00 mg/kg, Kunming mice (n=24) were randomly divided into blank control group and low,middle and high dose (1/50 LD50,1/20 LD50 and 1/10 LD50) groups (n=6 per group). Mice were treated with C7[MIM]Cl once a day by gavage for 28 days. The control group was given an equal volume of normal saline by gavage. The changes of food intake and body mass of mice were recorded;organ coefficients were calculated;serum biochemical indexes were detected;and the pathological changes of each organ were observed by H&E staining. RESULTS:The food intake in middle exposure group was lower than the control group (P=0.05). Serum biochemical indices showed that the activities of alanine aminotransferase (ALT) in the liver of the low exposure group was significantly increased (P=0.049). The total bilirubin (TBIL),UREA,uric acid (UA) and cholesterol (CHO) in the serum of the middle exposure group was significantly lower than the control (P<0.05). The glucose (GLU) level in the high dose group was significantly decreased (P<0.05). The observation of tissue section showed that different exposure doses induced a certain degree of damage to liver,spleen,lung,kidney and ovary. Especially,damages to the liver and kidney were more obvious. CONCLUSION:With sub-acute exposure of C7[MIM]Cl,liver and kidney were important target organs for damage from C7[MIM]Cl.
