Description
  • Here, we describe the effects of statins on the treatment of presbycusis in C57BL/6J mice. In this strain with accelerated aging, we demonstrate that animals treated with atorvastatin for 2 months showed larger amplitudes of distortion product otoacoustic emissions than did the non-treated control group. This finding indicates a better survival of outer hair cell function in the inner ear of C57BL/6J mice. The observed decreased expression of intercellular and vascular adhesion molecules in the aortic wall of atorvastatin-treated animals suggests that reducing endothelial inflammatory effects may contribute to the positive effect of atorvastatin on the amplitudes of DPOAE by influencing the blood supply to the inner ear. No such beneficial effect of statins was found in apoE-/- mice treated with atorvastatin under the same conditions. Our results suggest that statins could also slow down the age-related deterioration of hearing in man.

  • V této zprávě popisujeme účinky statinů na léčbu presbyakuzie u C57BL/6J myší. U tohoto kmene se zrychleným stárnutím ukazujeme, že zvířata léčená atorvastatinem po dobu 2 měsíců vykazovala větší amplitudy v testu otoakoustických emisí V porovnání s neléčenou skupinou. Toto zjištění naznačuje lepší zachování funkcí vnějších vláskových buněk ve vnitřním uchu C57BL/6J myší. Pozorovaná snížená exprese intercelulárních a vaskulárních adhezivních molekul ve stěně aorty atorvastatinem léčených zvířat naznačuje, že redukce endoteliálních zánětlivých účinků může přispívat k pozitivnímu účinku atorvastatinu na amplitudy DPOAE pomocí ovlivnění dodávek krve do vnitřního ucha. Žádný takový pozitivní účinek statinů nebyl objeven u ApoE/- myší léčených atorvastatinem za stejných podmínek. Naše výsledky poukazují na fakt, že statiny by také mohly zpomalovat věkem způsobenou zhoršenou sluchovou funkci u člověka. (cs)
