    The article presents an optimized method for the determination of the ratio of 8-oxo-2'-deoxyguanosine (formed in DNA due to the action of active forms of oxygen) to 2'-deoxyguanosine. The ratio was determined by reverse phase HPLC combined with amperometric detection. It was shown that the ratio increases upon oxidative stress caused by the action of large doses of ascorbic acid in samples of DNA isolated from the liver of experimental rats.Π’ Ρ€Π°Π±ΠΎΡ‚Π΅ ΠΏΡ€ΠΎΠ²Π΅Π΄Π΅Π½Π° оптимизация ΠΌΠ΅Ρ‚ΠΎΠ΄Π° опрСдСлСния ΠΎΡ‚Π½ΠΎΡˆΠ΅Π½ΠΈΡ 8-оксо-2'-дСзоксигуанозина, ΠΎΠ±Ρ€Π°Π·ΡƒΡŽΡ‰Π΅Π³ΠΎΡΡ Π² Π”ΠΠš Π² Ρ€Π΅Π·ΡƒΠ»ΡŒΡ‚Π°Ρ‚Π΅ дСйствия Π°ΠΊΡ‚ΠΈΠ²Π½Ρ‹Ρ… Ρ„ΠΎΡ€ΠΌ кислорода, ΠΊ 2'-дСзоксигуанозину ΠΌΠ΅Ρ‚ΠΎΠ΄ΠΎΠΌ ΠΎΠ±Ρ€Π°Ρ‰Π΅Π½Π½ΠΎ-Ρ„Π°Π·ΠΎΠ²ΠΎΠΉ Π’Π­Π–Π₯ Π² сочСтании с ампСромСтричСской Π΄Π΅Ρ‚Π΅ΠΊΡ†ΠΈΠ΅ΠΉ.

    The protective effect of cortexin was investigated with the use of acoustic stress hemorrhagic stroke model. A significant decrease of 8-oxo-2'-deoxyguanosine to 2'-deoxyguanosine ratio in the DNA molecule was shown using brain slices of cortexin treated Krushinsky-Molodkina rats.Π’ Ρ€Π°Π±ΠΎΡ‚Π΅ ΠΈΠ·ΡƒΡ‡Π΅Π½ΠΎ влияниС Π·Π°Ρ‰ΠΈΡ‚Π½ΠΎΠ³ΠΎ дСйствия ΠΏΡ€Π΅ΠΏΠ°Ρ€Π°Ρ‚Π° кортСксин Π½Π° ΠΌΠΎΠ·Π³ крыс Π»ΠΈΠ½ΠΈΠΈ ΠšΡ€ΡƒΡˆΠΈΠ½ΡΠΊΠΎΠ³ΠΎ-Молодкиной Π² условиях ΡΠΊΡΠΏΠ΅Ρ€ΠΈΠΌΠ΅Π½Ρ‚Π°Π»ΡŒΠ½ΠΎΠ³ΠΎ гСморрагичСского ΠΈΠ½ΡΡƒΠ»ΡŒΡ‚Π°, Π²Ρ‹Π·Π²Π°Π½-Π½ΠΎΠ³ΠΎ акустичСским стрСссом.
