  • Method for low-temperature preservation of spermatozoa
    Patent number: 4965186
    Abstract: The method resides in cooling the spermatozoa in a high thermal-diffusive powdered material that has preliminarily been cooled down to the refrigerant temperature. Cooling is carried out in a medium of a cryopreservative, containing a salt buffer, an antishock component, and a cryoprotector. The cryoprotector is taken in a concentration high enough for vitrification to develop in the spermatozoa. An example of the high thermal diffusive powdered material is alumina.
    Type: Grant
    Filed: June 21, 1988
    Date of Patent: October 23, 1990
    Inventors: Valentin I. Grischenko, Jury V. Kalugin, Jury S. Paraschuk, Nina A. Luchko, Elena N. Chernysh, Valery F. Tarasov, Sergei E. Galchenko
  • Method for low-temperature preservation of embryos
    Patent number: 4965185
    Abstract: The method consists in cooling of embryos down to the temperature of the refrigerant in a buffer-salt fluid, the cooling process being carried out in a temperature diffusive powdered material that has preliminarily been cooled down to the refrigerant temperature. The buffer-salt fluid comprises a mixture of cryoprotectors, i.e., glycerol, dimethylsulphoxide, and a dihydric alcohol. An example of the temperature diffusive material is powdered metal.
