Abstract

Već dugi niz godina ljudi se pitaju kako produžiti životni vijek organa čuvanih u ledu za transplantaciju. Odgovor je možda toliko jednostavan da ga ne primjećujemo. Mnoge životinje u prirodi uspješno prevladavaju niske temperature i oporavljaju se od zamrzavanja. Jedna od takvih je i šumska žaba, Rana sylvatica, koja svojim brojnim mehanizmima održava vijabilnost organa tijekom uzastopnih ciklusa zamrzavanja i odmrzavanja. Njene adaptacije poslužile bi kao model za zamrzavanje tkiva, organa, a možda i ljudi. U ovom radu izložen je kratki pregled prilagodbi koje šumska žaba koristi kao posljedicu izlaganja niskim temperaturama.

Abstract (english)

For a long time humans are asking how to prolong lifetime of the organs stored in ice for transplantation. The answer might be so simple we might not even see it. A lot of animals in nature survive low temperatures and freezing. One of them is the wood frog, Rana sylvatica. The wood frog has many mechanisms for maintaining viability of organs during periods of freezing and thawing. It's adaptations could serve as a model for freezing human tissues, organs and maybe even whole organisms. In this work has been presented a short review of adjustments that wood frog developed as a result of influence of low temperatures on its body.
