摘要:

目的:配制含有多酸化合物的新型洗手液,并探讨其在人手部抗流感病毒的效果和安全性。方法:采用MDCK细胞
流感病毒模型研究2种多酸化合物K10Na[(VO)3(SbW9O33)2]?26H2O(PM-1001)和K15[Pr(BW11O39)2]?28H2O(Pr-B)
的体外抗病毒作用,选择3个适宜的多酸剂量配制成含高、中、低剂量多酸洗手液;依据美国标准方法进行洗手液抗病毒效果评价,含2种多酸化合物的洗手液各有5名志愿者参与实验,将每名志愿者的10个手指随机分成5组,在手指上涂0.02 mL组织培养半数感染剂量(TCID50)为107.5/0.1 mL的病毒悬液后,分别在加病毒后、病毒液晾干后和用不同洗手液处理后收集病毒,采用MDCK细胞培养法测定病毒滴度;检测流感病毒在手部晾干30和60 min后的浓度和活力变化;选择含高浓度PM-1001的
洗手液,按照《消毒技术规范》(2008版)利用昆明小鼠和白色家兔进行毒性评价。结果:PM-1001和Pr-B抗流感病毒的治疗指数(TI)分别为82.68和69.13;对照组的病毒浓度为104.33±0.66TCID50/0.1 mL,各洗手液处理组组织培养法均未检测到病毒,各洗手液处理组病毒浓度均低于对照组(P<0.001),30和60 min收集的病毒浓度分别为103.98 ±0.42TCID50/0.1 mL和103.83±0.35TCID50/0.1 mL,与对照组比较差异无统计学意义(P>0.05);含高浓度PM-1001的洗手
液对昆明小鼠的经口毒性实验半数致死浓度(LD50)大于5 000 mg/kg-1(体质量),对家兔完整皮肤刺激指数为0.33,对3只家兔眼刺激的平均评分分别为0、0.67和0.33。结论:含多酸化合物的新型洗手液可有效抑制手部甲型流感病毒,属实际无毒级的物质,对家兔完整皮肤和眼无刺激性。

Abstract:

Objective To prepare a new hand-washing agent with heterpolyoxometalates and to study its anti-A-influenza virus effect and toxicity.
Methods The anti-virus effects of the two compounds K10Na[(VO)3(SbW9O33)2]?26H2O(PM-1001) and K15[Pr(BW11O39)2]?28H2O(Pr-B) were detected on MDCK cells.Three levels  of heterpolyoxometalates(high,middle,and low doses)were chosen to add into hand-washing agents; the anti-A-influenza virus effect
 
test was performed according to the American Society for Testing and Materials(ASTM) standard assessment protocols.In this test,10 volunteers were randomly divided into two groups for testing hand-washing agents with PM-1001 and Pr-B respectively.Every volunteer’s ten fingers were divided into 5 groups randomly.After all the finger taps were contaminated with 0.02 mL of 107.5 tissue culture infectious dose (TCID50)/0.1 mL live human influenza A virus, the H1N1 titers  were assessed with MDCK cell culture method after  contaminating,air drying and treatment with different hand-washing agents.The
concentrations and  viabilities of H1N1 on hands  30 and 60 min after hand drying  were also assessed.The hand-washing agent with  high dose of PM-1001 was chosen for toxicity assessment using Kunming mice and rabbits according to Disinfection Technical Specifications (2008).
Results The  therapeutic indexes  (TI) of PM-1001 and Pr-B   were  82.68 and 69.13.The H1N1 concentration in  control group was 104.33±0.66TCID50/0.1 mL
.The fingers in treatment groups had no viable H1N1 recovered.The virus concentrations in  treatment groups had significant differences compared with  control group(P<0.001).The H1N1 virus concentrations  in  30 and 60 min groups were 103.98 ±0.42TCID50/0.1 mL and 103.83±0.35TCID50/0.1 mL and had no significant differences compared with  control group(P>0.05).The LD50 in  mouse acute toxicity test  was >5 000 mg/kg-1,the rabbit skin irritation index was 0.33,and the eye stimulation indexes of three rabbits were 0,0.67, and 0.33. Conclusion The new  hand-washing agents including PM-1001 and Pr-B are highly effective in reducing influenza A virus on human hands.It has no toxicity and no stimulation to skin and eyes of rabbits.

Key words: heterpolyoxometalates, hand-washing agent, influenza A virus, toxicity
