백서 가토 및 닭의 여러장기에서 dehydro-L-ascorbic acid reductase(DHA-reductase)의 활성을 측정하고 다음과 같은 결과를 얻었다. 1) 백서 가토 및 닭의 각 동물의 간, 뇌, 신, 소장, 근육, 부신에서 DHA-reductase 활성은 모두 부신에서 높았고, 근육에서 가장 낮았다. 간, 뇌, 소장에서 DHA-reductase 활성은 부신에서 보다는 낮고, 근육에서 보다는 높았다. 그리고 신장에서는 간, 뇌, 소장에서 보다 약간 낮았다. 2) 간에서 DHA-reductase 활성은 백서와 가토에서는 생후 일차 떨어지다가 다시 증가 하였고, 닭에서 생후 처음부터 증가 하였다. 3) 백서에서 DHA-reductase 활성은 cytosol에만 있었다.
Dehydro-L-ascorbic acid reductase (DHA-reductase) activities in various tissues of rats, rabbits and chicken were determined and the following results were obtained: 1) Among the DHA-reductase activities in liver, brain, kidney, small intestine, muscle and adrenal of rats, rabbits and chicken, the highest activity was found in adrenal and the lowest activity in muscle of each animal. The DHA-reductase activities in liver, brain and small intestine were lower than that in adrenal, but were higher than that in muscle of each animal and the activity in kidney was slighly lower than those in liver, brain and small intestine. 2) DHA-reductase activities were decreasing immediately after the birth but soon were increasing in liver of rats and rabbits, but the DHA-reductase activity in liver of chicken was increasing immediately after the birth. 3) DHA-reductase activity in rats was found only in cytosol.
