Abstract

The changes in nucleotide content during CBrCl3 treatment were investigated. In the first 5-10 minutes a significant ATP decrease was detected. The GTP loss leading to 57% of the initial level after 10 min surpasses the ATP loss which leads to 70% of the initial value after 10 min. The increase in uric acid is not only the result of CBrCl3 induced reaction, because of no significant changes in adenine and hypoxanthine values. The uric acid pool reflected different influx and efflux processes. These changes were compared with nucleotide degradation and accumulation of nucleotide degradation products during anoxia.
