Cell suspension cultures of Ajuga reptans L. and Serratula coronata L. were derived from long-cultured calluses. Their growth patterns and morphophysiological characteristics indicated that these cells adapted well to grow in suspensions. During the growth cycle of cell suspension, the main ecdysteroid, among others present in plants, was 20-hydroxyecdyson(More)
Content of phosphoribosyl pyrophosphate and the activity of ribose phosphate pyrophosphokinase and AMP-pyrophosphorylase were studied in erythrocytes of healthy persons and of patients with various types of anemia. Deficiency of phosphoribosyl pyrophosphate and a decrease in the activity of enzymes studied were observed in erythrocytes under(More)
L. Lapicque [5] has developed the concept of the subordinative effect of centers, based on the observed increase in excitability and prolongation of chronaxie following transection of a nerve. It has, however, been shown by Nasonov and Rozentai' [8] that these changes in excitability are due to impulses proceeding from the point of transectionof the nerve.(More)
Effect of thermic treatment and of pre-incubation with phosphoribosyl pyrophosphate on activity of AMP- and IMP-pyrophosphorylases were studied in leukocytes under chronic forms of limpho- and myeloleukoses. AMP-pyrophosphorylase from leukemia leukocytes was inactivated after heating up to 65 degrees, which, at the same time, as distinct from the enzyme of(More)
