[Glutamate-oxalacetate-transaminase in irradiated and nonirradiated chick embryos].
The enzymatic activity of glutamate-oxalacetate transaminase (GOT) in 16 days old chick embryos was investigated in 10 minute-intervals following X-ray irradiation with 1000 R. Initially, in the tissue homogenates of the embryos and in the blood serum a decline of enzyme activity was observed, which continued for 30 minutes after irradiation. Subsequently - during a second phase - the enzymatic action was increased far beyond the norm. On the contrary, in the tissues of the allantois no significant change of the GOT-concentration was seen following irradiation.
