Effects of pretreatment with an indeno-indole compound on lipid peroxidation in the cortex and medulla of rabbit kidneys after ischaemia-reperfusion.
The effects of 60 min of ischaemia with or without reoxygenation in vivo or in vitro on lipid peroxidation in cortical and medullary tissue from rabbit kidneys were measured as production of thiobarbituric acid-reactive substances (TBARS). Lipid peroxidation was more pronounced in medullary tissue compared with cortical tissue. The highest TBARS production was found in medullary slices subjected to reoxygenation in vitro immediately after 1 h of ischaemia. Reperfusion in vivo before reoxygenation in vitro attenuated the TBARS formation during subsequent in vitro incubation. Pretreatment of the rabbits with an indeno-indole compound (code name H 290/51) reduced the TBARS formation after 60 min of ischaemia and reoxygenation in vitro towards control values.
