   <abstract xml:lang="ru">
    <p>В работе представлены результаты измерения кинетики длительной люминесценции эритрозина в опухолях и здоровых тканях молочной железы лабораторных мышей. Обнаружен эффект тушения замедленной флуоресценции в режиме строб-периодического возбуждения люминесценции, зависимый от частоты следования лазерных импульсов. Установлена связь описанного эффекта с уменьшением вклада в свечение реакций кросс-аннигиляции триплет-возбуждённого люминофора и синглетного кислорода. Проанализировано влияние тушения замедленной флуоресценции на интенсивность фосфоресценции зонда. Показано, что с помощью описанного явления можно оценить расходование тканевого кислорода в ходе фотодинамических процессов.</p>

    <p>The decay kinetics of erythrosine delayed luminescence in malignant and healthy biological tissues of laboratory mice was investigated. Upon periodical pulse excitation of luminescence an effect of delayed fluorescence suppression was discovered. The glow quenching value is dependent on the laser pulses repetition period. It is shown that the effect is associated with the decrease in the contribution of luminescence via photogenic annihilation reaction of triplet sensitizer and singlet oxygen excited states. In addition, the oxygen-dependent fluorescence decay affecting to the phosphorescence intensity is discussed. The obtained data suggest that it is possible to evaluate intensive oxygen consumption into a tissue using annihilation delayed fluorescence.</p>
