The invention provides a method for analyzing drugs in tissues. Quantitative analysis and detection are carried out on drug distribution conditions in in-vitro tissues by adopting a quantitative whole-body radioautography (QWBA) technology and a tissue embedding section. According to the invention, transverse slicing after longitudinal slicing is avoided, the experiment time is saved, the structure of each layer of the skin is accurately positioned, and the distribution condition of drugs in the cuticle, epidermal layer, dermis layer and subcutaneous tissue of the skin can be visually observed. And similar effects are achieved on other tissues.

The invention discloses a rapid tableting method of a large-sized alga in-vitro dyeing epidermal lamella. The method comprises the following steps of: preparing a mixing reagent; completing dissociation at one step, and dyeing a large-sized alga epidermal lamella; and manually operating to rapidly prepare an epidermal cell lamella of which the area can be up to 1cm<2>. The method is easy and convenient to operate, has a high preparation speed, a good color development effect and high stability, and is suitable for observation through microscopes and electron microscopes and observation and research of epidermal cell ultrastructures.
