Abstract
The influence of low-frequency vibration (frequency range 8–32 Hz, amplitudes 0.5 ± 0.04 and 0.9 ± 0.08 mm) on the erythrocytes’ acid resistance was studied. The kinetics of various hemolysis stages was investigated. The time-frequency dependences of the kinetics constants of hemolysis stages were obtained and discussed. It was shown that 8–16 Hz vibration with the 0.5 mm amplitude and 8 Hz with 0.9 mm causes destructive reorganizations of a cytoplasm’s water-protein structure. It leads to decrease in a permeability barrier for a hemolytic agent. As a result of oxidizing stress the vibration in the frequency range of 20–32 Hz causes the modifying reactions leading to the aggregation of cellular proteins and, in particular, the band 3 protein.
تمت دراسة تأثير الاهتزاز منخفض التردد (نطاق التردد 8–32 هرتز، وبسعات 0.5 ± 0.04 و0.9 ± 0.08 ملم) على المقاومة الحمضية لكريات الدم الحمراء. وجرى استقصاء حركيات المراحل المختلفة لانحلال الدم، كما تم الحصول على التبعيات الزمنية-الترددية لثوابت حركية مراحل انحلال الدم ومناقشتها. وأظهرت النتائج أن الاهتزاز بتردد 8–16 هرتز بسعة 0.5 ملم، وبتردد 8 هرتز بسعة 0.9 ملم، يتسبب في إعادة تنظيم تخريبية للبنية المائية-البروتينية في السيتوبلازم، مما يؤدي إلى انخفاض حاجز النفاذية أمام العامل الحالّ للدم. ونتيجة للإجهاد التأكسدي، يتسبب الاهتزاز في نطاق التردد 20–32 هرتز في حدوث تفاعلات تحويرية تفضي إلى تجمّع البروتينات الخلوية، ولا سيما بروتين الحزمة 3 (Band 3 protein).
