[Content of ATP and glucoso-6-phosphate in the dogs' bone marrow cells after cryopreservation].

: The content of ATP and glucoso-6-phosphate in the dogs' bone marrow cells before and after cryopreservation in liquid nitrogen have been studied. It has been found that ATP and glucoso-6-phospate levels in the dog bone marrow cells after cryopreservation in liquid nitrogen without cryoprotectors was very low. Solutions of DMSO and PEO-400 were used as cryoprotectors. The DMSO was more effective than PEO-400, because no metabolic changes were observed in incubated and freezed-thawed cells there.
