Heterocyclic derivatives of butylated hydroxytoluene (BHT) were studied as cryoprotectants of the basic media for cryopreservation of the Russian sturgeon sperm. Rates of lipid peroxidation of sturgeon sperm before and after cryopreservation were reduced in the presence of the studied compounds, exceeding the effects of BHT and water-soluble analogue of vitamin E, trolox. The most efficient antioxidant...
A cryoprotective effect of an addition of a new synthetic antioxidant – a representative of phosphorus-containing sterically hindered phenols is presented. The efficiency of the compound was shown to exceed the effect of lipid-soluble antioxidants butylated hydroxytoluene (BHT) and trolox in the conditions of cryopreservation of beluga sperm in the presence of the modified Stein’s medium. It was shown...
