title: [Morphological and histochemical characteristics of the organism's reaction to administration of Cl botulinum toxin. IV. Cytochemical changes in the cells of the mesencephalic nucleus of trigeminal nerve following administration of Cl. botulinum type B toxin].
abstract: After the administration to guinea pigs per os of 1 Dlm of botulin toxin, type B, a change of the RNA synthesis in the nucleoli and DNA depolymerization in the nuclei was observed in some of the cells of the mesencephalic nucleus of the trigeminal nerve. An increase in the activity of succinic dehydrogenase and of acid phosphatase coursed without any necrotic processes in the cells. Basing upon the changes in the activity of succinic dehydrogenase in the neurons of the mesencephalic nucleus a conclusion was drawn that hypoxia began to develop at the period of appearance of paralyses of the limbs and reached its maximum in myasthenia.
