Abstract
Glutamic-oxalacetic transaminase in serum was determined towards the end of pregnancy. The determinations were made before and after incubation of the serum with pyridoxal phosphate and after the patients had been receiving pyridoxine orally for a fairly long time. Neither medication with pyridoxine nor incubation of the serum with pyridoxal phosphate produced an increase in transaminase activity. Thus, judging by the activity of glutamic-oxalacetic transaminase in serum, under the conditions of the study, pregnancy is not accompanied by a deficiency of vitamin B6.
