Mechanisms of drug incorporation into hair.

摘要: The model generally proposed to explain the incorporation of drugs into hair is one in which enter only by passive diffusion from blood stream growing cells at base follicle. However, this may be over-simplified. More recent experimental findings suggest that multiple sites, via mechanisms, and various times during growth cycle. A more complex metabolites are incorporated formation shaft (via actively follicle), after secretions apocrine sebaceous glands), has emerged skin (from external environment). Further, can transferred body compartments or pools located tissues surrounding These mechanisms could also drug-specific. precise understanding involved critical for forensic scientists order interpret results analysis properly.
