[THE USING OF THE METHOD OF RECONSTRUCTION OF OPTICAL CROSS SECTIONS FOR INVESTIGATION OF THE TROPHOTROPIC EFFECTS OF ADRENALINE AND ATENOLOL].

The trophotropic effects of epinephrine and atenolol were investigated by using the organotypic culture method combined with the method of the reconstruction of optical cross sections. For the best possible image contrast was experimentally established the correction for Petri dish bottom thickness equal to 1 mm (objective lens Carl Zeiss). It was shown by method of the reconstruction of optical cross sections that growth zone in organotypic culture forms a multidimensional structure. In the presence of atenolol (10(-4) M) the thickness of the growth zone of the cardiac tissue explants was above the reference value 212%. The thickness of the growth zone in the presence of epinephrine (10(-9)-10(-13) M) did not differ from the control values. Experimentally was proved that atenolol mimics the trophotropic effects of epinephrine and these effects of epinephrine is realized primarily through ß1-adrenergic receptors.
