Drugs postmortem

Drugs postmortem - educational and scientific programs (micropreparative) from painful changed organs, tissues, body parts, specially processed for storage and demonstration of pathological changes. Material for pathological preparations are various organs and tissues removed during surgery or during the autopsy, which are subjected to commit, and then canning in a 10% solution of formaldehyde. To lock the object should be given the need to demonstrate form, as after fixing tissue thicken and become intractable, for example, part of the intestine or flap leather pull on a cardboard, a hollow body put cotton wool for shape retention etc. Locking liquids can serve as a medium for the storage of pathological drugs (Fig. 2). Where preservation of natural color, pathological preparations handle 96% alcohol to restore the natural color fabrics and conclude in a liquid with a high content of glycerin - wet storage method (Fig. 3). At a dry method of storage of organs and tissues enclosed in hermetically sealed vessels of glass, Plexiglas and other (Fig. 4 and 5). Bone pathology drugs after maceration (see) and drying keep dry. Vascular network on postmortem drugs injected opaque mass, fix, illuminate and remain in glycerine.

Drugs postmortem - long lasting fixed diseased organs, tissue or body part, seized at the opening or during the operation and used for demonstration purpose as a textbook. There PP wet stored in sealed glass or plastic cans with special liquids or plastic, and dry (bone).
Wet pathological preparations can be stored in 10% formalin solution, but the tissues lose their natural color. For the latest methods of restoration of the painting and the subsequent preservation of the object. The most common, accessible and cheap is the method of N. F. Melnikov Razvedenkova (fixed in formalin-salt mixture, restoration of color in alcohol and conservation in the solution of glycerin). Relatively simple, but less reliable method Peak - Jorisa, which as a retainer, preserving the natural colouring of fabrics, use a solution of formalin with the addition of carlsbad salt and chloral hydrate. More perfect is the method Romhanyi, where applicable, however, more expensive and rare reagents (pyridine, nicotine). Very promising new method of conclusion p.p. in plastics, for example, metilmetakrilat.
Bone (dry) pathological preparations manufacture of maceration parts of the skeleton with the subsequent washing them in water, then consecutive immersion in a solution of soda, ether and whitening hydrogen peroxide. Bone drugs can save by mounting glazed in special boxes. They can be manufactured as a normal wet PP
In the manufacture of pathological preparations necessary to commit the body, especially the hollow, or tissue to give the object a necessary demonstrative form to fill a cavity absorbent cotton, stretch flat drugs on Board or Board. You can also pre pour vessels color hardening masses and implement enlightenment object by treatment with methyl ester of salicylic acid with subsequent conclusion of the drug in glycerin or polystyrene.
