The results of comparative clinical application of low-molecular heparin Clexan vs heparin for the thromboembolic complications prophylaxis in surgical treatment of morbid obesity were summarized.

Two types of PS II centres as manifested by light saturation of delayed fluorescence from DCMU-treated chloroplasts.

Intensity of 2 s delayed fluorescence (DF) as a function of steady-state actinic light intensity was investigated in pea chloroplasts in the presence of 10 µM DCMU. The light saturation curve of DF was approximated by a sum of two hyperbolic components which differ by an order of magnitude in the half-saturating incident light intensity. The relative contribution of the amplitudes of the components was practically independent of cation (Na(+) and Mg(2+)) concentration and a short-term heating of the chloroplasts at 45°C. The component saturating at low incident light intensity was selectively suppressed by 100 µM DCMU or by 1 µmol µg(-1) Chl oleic acid. DF intensity following excitation by a single saturating 15 µs flash was equal to the intensity of the component saturating at a low incident light intensity. Upon flash excitation, the maximum steady-state DF level was found to be attained only after a series of saturating flashes. It is concluded that the two components of the DF light saturation curves are related to PS II centres heterogeneity in quantum yield of stabilization of the reduced primary quinone acceptor.
