Abstract
Despite various kinds of animal testings used to explore intestinal resorption of drugs after oral uptake there is still no satisfying method established to estimate these processes in a human body. The difficulty is due to species differences as well in metabolic processes as in actions of drugs, that complicate usage of blood concentration or medical surveillance for analysis. We succeeded in obtaining isolated jejunal segments of rats and pigs in vitro. Longer than 5 days cells still showed typical immuno-histological markers of cell types naturally found in the intestine. Longer than 9 days there still was an obvious peristaltic movement in cultured pig intestine. By using isolated jejunal segments of different species for uptake studies under well defined conditions it is more easy to analyse uptake amounts, species differences and other influencing factors. Moreover animal testings could be reduced and replaced.
