The development of activity of succinate dehydrogenase (EC.1.3.99.1) in the areas of the nigro-striatal pathway during the ontogenesis of a pig.
The development of activity of succinate dehydrogenase was investigated by histochemical methods under the light and electron microscopes and also by biochemical methods. The studies were carried out in the areas of the nigro-striatal pathways of 7 foetal groups, two day-old piglets, three week-old piglets and adult pigs. It was demonstrated that the activity of succinate dehydrogenase appeared first in foetuses of about 86 days (180 mm). The highest activity in prenatal development appeared just before birth in about 112 days old (260 mm) foetuses. After birth in 2 day-old piglets the activity of the examined enzyme decreases, while in 3 week-old it increases however not reaching the activity level observed in adult pigs.
