[Short-time storage of human corneas in medium NCTC 135 (author's transl)]. 1978

H W Holtmann, and H J Stein

20 human donor corneas were placed in a tissue culture medium (NCTC 135 with an additional content of 5% Actovegin resp. Solcoseryl) at +4 degrees C for 5 and 7 days. After that the temperature reversal effect was measured and the corneal endothelial cells were stained. The living cells were counted every 24 hours until no more cells could be seen. It could be shown, that compared with the MK-Medium 24% more living cells could be counted after 5 and 7 days storage in the medium. Possible causes of this improvement, practical consequences with including antibiotic prophylaxis are discussed.

UI	MeSH Term	Description	Entries
D003315	Cornea	The transparent anterior portion of the fibrous coat of the eye consisting of five layers: stratified squamous CORNEAL EPITHELIUM; BOWMAN MEMBRANE; CORNEAL STROMA; DESCEMET MEMBRANE; and mesenchymal CORNEAL ENDOTHELIUM. It serves as the first refracting medium of the eye. It is structurally continuous with the SCLERA, avascular, receiving its nourishment by permeation through spaces between the lamellae, and is innervated by the ophthalmic division of the TRIGEMINAL NERVE via the ciliary nerves and those of the surrounding conjunctiva which together form plexuses. (Cline et al., Dictionary of Visual Science, 4th ed)	Corneas
D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture

D000183	Actihaemyl	An extract from calf blood containing inorganic salts, amino acids, polypeptides and purines, but no proteins nor antigenic substances or blood group characteristics. Its exact composition is unknown. It has been proposed as a radiation-protective agent.	Solcoseryl,S 1021

D014021	Tissue Preservation	The process by which a tissue or aggregate of cells is kept alive outside of the organism from which it was derived (i.e., kept from decay by means of a chemical agent, cooling, or a fluid substitute that mimics the natural state within the organism).
