From: The mode of action of dimeticone 4% lotion against head lice, Pediculus capitis
Effect of dimeticone 4% lotion on the integrity of the gut in head lice. This sequence of images was taken from a continuous video observation of head lice treated with dimeticone 4% lotion over a period of 17 hours. The gut of the larger louse first showed signs of rupture approximately 5 hours after treatment (arrowed, image b), with blood release over 2–3 hours spreading throughout the thorax and into the limbs (arrowed, image f). The small louse's gut ruptured approximately 14.5 hours after treatment with seepage into the thorax (arrowed, image h). After 17 hours the larger louse appeared dehydrated (image i).
