Abstract
The recovery of serum GOT and GPT activities which were lowered in vitamin B_6-deficient rat, was more prompt and retained high value for longer time in pyridoxal-homocysteine administration than that in pyridoxal or its phosphate administration. The blood pyridoxal phosphate level was also higher in the former than that in pyridoxal phosphate administration. Pyridoxal-homocysteine did not show any marked effect on cardiovascular system or gastrointestinal tract as well as the latter two.
