[Supramolecular reorganizations in cellulose during hydration].

The analysis of modern ideas about the structural organization of the cellulose microfibrils is carried out. The mechanism of the formation of additional capillary-porous system of cellulose under moistening is offered. It is established that when the moisture content of cellulose reaches 8-10%, the filling of its micropores occurs with a simultaneous increase in their cross sizes, a specific surface and reduction in the degree of crystallinity of specimens.

[Inhibition of liver mitochondrial monoamine oxidase activity by alkaloids isolated from Chelidonium and Macleaya and by their derivative drugs].

It has been shown that the major alkaloids from plants Chelidonium majus L. and Macleaya (Bocconia) cordata and microcarpa, namely, berberine, sanguinarine, chelidonine, and drugs "Ukrain" (thiophosphoric acid derivative of a sum of the alkaloids isolated from Ch. majus L.

[The inhibition enzymatic hydrolysis of acetylthiocholine by acetylcholinesterase using principal alkaloids isolated from celandine and macleya and their derivatives].

A study was made of a possible inhibitory action on the enzymatic hydrolysis of acetylthiocholine by human erythrocyte acetylcholinesterase of principal alkaloids isolated from Chelidonium majus L. and Macleaya (Bocconia) cordata and microcarpa (namely sanguinarine, chelidonine, berberine), and of drugs "Ukrain" (thiophosphoric acid derivative of a sum of the alkaloids isolated from Chelidonium majus L.) and "Sanguirythrine" (a mixture of unseparated closely related to benzo[c]phenanthridine alkaloids sanguinarine and chelerythrine, isolated from Chelidonium majus L.
