防止血吸虫尾蚴侵入皮肤有三种設想:其一是以某些藥物涂在皮肤上以毒害尾蚴,使尾蚴不敢接近皮肤以达到驅避的目的,或使尾蚴在尚未侵入皮肤之前即已丧失其侵入能力甚至死去。这是一种藥物性質的防止尾蚴侵入皮肤的方法。其二是用一些物質遮住皮肤使尾蚴无从接触皮肤,阻擋尾蚴侵入。这是一种机械性質的防止尾蚴侵入皮肤的方法。其三是在遮住皮肤的物質中摻加一些藥物使起阻擋与毒害的双重作用。这是机械性質与藥物性質兼而有之的防止尾蚴侵入皮肤的方法。
There are three scenarios for preventing the invasion of schistosome cercariae into the skin: one is the application of certain drugs to the skin to poison the cercariae, so that the cercaria does not dare to approach the skin for repellent purposes, or the cercariae have lost their invasion before they have invaded the skin. The ability to die even. This is a drug-like method to prevent the tail from invading the skin. The second is to cover the skin with some substances so that the tail can not touch the skin, blocking the invasion of the cercariae. This is a mechanical method to prevent tail lice from invading the skin. The third is to add some drugs to the skin-blocking substances to make them more resistant to blocking and poisoning. This is a combination of mechanical properties and drug properties that prevent the tail from invading the skin.
