1. Taurine is found as a free amino acid in plasma and many tissues su
ch as heart, muscle, brain and blood. Its exact role is not fully defi
ned but it appears to have an important effect on the function of the
heart. 2. The purpose of this study was to investigate the effects of
taurine (10(-3) M and 10(-2) M) on malondialdehyde levels in perfused
heart muscle. 3. In this study we found that administrated taurine bef
ore anoxia and reperfusion increased the malondialdehyde levels but ad
ministrated taurine after anoxia decreased the malondialdehyde levels
in perfused heart muscle compared to the taurine administrated group b
efore anoxia. 4. Anoxia did not change the perfused heart muscle malon
dialdehyde levels.
