The effects of alamethicin on the membrane barrier function of rabbit erythrocytes, human platelets and sarcoplasmic reticulum vesicles, as well as on that of brain microsomes and liver mitochondria of the rat were compared. An upset of the barrier function was observed for plasma membranes of brain microsomes as well as for erythrocyte and platelet(More)
Reduced intensity of delayed fluorescence of chlorophyll and suppressed growth recorded in an experimental population of Scenedesmus quadricauda under the influence of pyrocatechol demonstrate reduction in efficiency of light reactions of photosynthesis, which, in turn, determines deterioration of algae productivity.
The effect of a dangerous toxic substance, methylmercury, on light dependence curves of chlorophyll fluorescence in Chlamydomonas moewusii was studied. We found low concentration of methylmercury (10–7 M) to cause a decrease in the relative rate of the non-cyclic electron transport activity of PS2, a decline in the maximum utilization of light energy (α),(More)
Activity of the enzyme systems protecting membrane structures of photoreceptor cells Ithe outer and inner segments of the retinal rods) against active forms of oxygen (superoxide dismutase) and lipid peroxide (glutathione peroxidase, glutathione reductase) was shown to be low. At the same time a high concentration of α-tocopherol (vitamin E) was(More)
A decrease in the content of vitamin E (tocopherols) in biological membranes leads to their injury [3]. Tocopherols, as minor lipid components of biomembranes, are considered to perform mainly the function of antloxldants, capable of interacting with free radicals of llplds [15] and with singlet molecular oxygen [8]. At the same time, tocopherols are known(More)
