It was found that the true sacciform structure with all components characteristic for adult animals was formed by the 20th day of postnatal development. Histological data have shown than the sacciform structure is formed in ontogenesis as a result of a complex epidermal transformation involving muscular and connective tissues which comprise the external coat. The structure studied is not formed on the basis of sebaceous glands and cannot be assigned to the class of gland as considered before.</p>","PeriodicalId":14529,"journal":{"name":"Izvestiia Akademii nauk SSSR.

In terms of estimated kinetic characteristics of AChE-reaction (KM, Vmax, KI), the pattern of enzyme inhibition by the hindered phenol compounds was found to be of non-competitive or mixed type depending on the inhibitor structure or on the substrate acetylcholine or acetylthiocholine used. The comparative study of the inhibitory action of water-soluble derivatives of hindered phenols and fatty-soluble ionol made it possible to reveal possible contributions to the inhibition of both direct and mediated (by the membrane microsurroundings) effects on the membrane-bound AChE by the studied synthetic bioantioxidants.</p>","PeriodicalId":14529,"journal":{"name":"Izvestiia Akademii nauk SSSR.
