This minimizes errors introduced by variations in distribution, metabolism and excretion of the drug. Several equations can be used to express the area, based on body weight, but conversion tables are usually used. See Table 21.

The body louse also has "the smallest number of detoxification enzymes observed in any insect," the researchers wrote in a report appearing in the Proceedings of the National Academy of Sciences.
The body louse is completely dependent on humans for its survival; it will die if separated from its host for very long.
So too are the genomes of the bacterial pathogens that the body louse transmits to its human hosts: Rickettsia prowazekii (which causes epidemic typhus), Borrelia recurrentis (the agent of relapsing fever) and Bartonella quintana (which causes trench fever).
This, the researchers report, will make the body louse a useful tool for understanding the co-evolution of disease-carrying parasites and their bacterial co-conspirators.
