Eighty patients (age range 4-10 years) with head lice infection were recruited to the study. Forty patients were treated with a single application of 0.2% w/v phenothrin liquid shampoo and 40 with 0.2% w/v malathion lotion. Inspection of the patients one week later revealed that no live lice remained in either group, but that two patients had viable eggs in the malathion lotion group. Re-inspection four weeks after application revealed that five patients of the phenothrin shampoo group and seven of the malathion lotion group had viable eggs. Live lice were not seen to be present in either treatment group. The results indicate that both products are effective in the treatment of head lice infection and that the phenothrin shampoo would be a useful addition to the insecticides currently employed.
80名头虱感染患者（年龄范围4至10岁）被纳入该研究。40名患者单次使用0.2%（w/v）氯菊酯液体洗发水进行治疗，40名患者使用0.2%（w/v）马拉硫磷洗剂进行治疗。一周后对患者进行检查发现，两组均无活虱残留，但马拉硫磷洗剂组有两名患者有存活的虱卵。用药四周后再次检查发现，氯菊酯洗发水组有5名患者有存活的虱卵，马拉硫磷洗剂组有7名患者有存活的虱卵。两个治疗组均未见活虱。结果表明，两种产品对头虱感染均有效，且氯菊酯洗发水将是目前使用的杀虫剂的有益补充。
