目的了解深圳市龙岗区居民集体服药驱除肠道线虫效果。方法于2006年9月对肠道线虫感染高的龙岗区区居民集体服甲苯咪唑糖片驱虫,2007年1月经盐水漂浮法和改良加藤氏法粪检调查550名居民的感染情况,分析驱虫效果。结果肠道线虫卵总检出率为18.73%(103/550)。单虫阳性率以鞭虫卵最高,为9.27%,钩虫卵次之,为6.36%,蛔虫卵最低,为4.00%。用饱和盐水漂浮法检出率为8.18%;改良加藤氏法检出率为10.36%,经统计学处理(χ2=1.296,P>0.05),无统计学意义。从单虫检出情况看,盐漂法检出钩虫卵阳性21人,加藤法为13人,经统计学处理无统计学意义((χ2=3.379,P>0.05)。蛔虫卵分别检出16人和6人,显示盐漂法明显高于加藤法(χ2=4.638,P<0.05)。鞭虫卵检出分别为12人和39人,显示加藤法明显高于盐漂法(χ2=29.987,P<0.01)。结论甲苯咪唑糖片对人体肠道线虫有良好的驱除效果。通过集体驱虫后当地肠道线虫感染率大副下降。
Objective To understand the residents of Longgang District, Shenzhen, the collective medication to eliminate intestinal nematode effect. Methods In September 2006, residents of Longgang District, who were infected with gut nematodes, were given compound dexamethasone for detoxification. In January 2007, 550 residents were investigated for their infection by saltwater floating and modified Kato’s method. effect. Results The total detection rate of intestinal nematode eggs was 18.73% (103/550). The highest positive rate of whipworm eggs was 9.27%, followed by hookworm eggs at 6.36%, and the lowest ascaris egg count was 4.00%. The detection rate with saturated brine was 8.18%. The detection rate of modified Kats’ method was 10.36%, which was not statistically significant (χ2 = 1.296, P> 0.05). From the single insect detection situation, salt drift method detected hookworm eggs were 21 positive, Kato method was 13, the statistical analysis was not statistically significant (χ2 = 3.379, P> 0.05). Ascaris eggs were detected 16 and 6, respectively, showed that the salt drift method was significantly higher than that of Kato (χ2 = 4.638, P <0.05), and that of whipworm eggs was 12 and 39 respectively, indicating that Kato was significantly higher than salt drift (χ2 = 29.987, P <0.01) .CONCLUSION Tolmbatazole tablets have a good repellent effect on human intestinal nematode.After the collective deworming, the local gut nematode infection rate decreased.
