ABSTRACT
The infestation status of head louse among children attending primary schools and kindergartens in Chinju-shi, Kyongsangnam-do, Korea, was investigated between June and July 1999. Out of 2,288 children examined, 3.9% of boys (48/1,242) and 23.5% of girls (246/1,046) were infested with nits or adult/nymphs of lice. The effectiveness of lindane shampoo (1% gamma benzene hexachloride solution) was evaluated after one or two time applications to all the children infested. The negative conversion rate of pediculosis was 93.5%. Effective control measures are needed to control and prevent such ectoparasite infestation amongst children.

Progesterone receptors (PR) were identified with an enzyme immunoassay in cytosols from human arachnoid granulations and arachnoid cysts. Meningiomas presumably originate from subdural endothelium which is abundantly present in these structures. In the three cases studied, oestrogen receptors were absent. The presence of PR in subdural endothelium may provide further ground for the expression of PR in meningiomas.
