The study presents the results of the study of adaptive reactions and adaptive potential of the circulatory system of patients with vibration disease and chronic bilateral sensorineural hearing loss.

Biological age and rates of aging of patients with vibration disease and bilateral sensorineural hearing loss were studied. The biological age of patients exceeded the calendar age by an average of 7.36±0.36 years and the proper biological age by 10.79±0.72 years. The rate of biological aging of the examined patients was 1.14±0.08 times higher than the rate of aging of their healthy peers.

Comparative study of the structural and functional state of cerebral cortex of adult albino rats after intracerebral allo- and xenotransplantation of embryonic nervous tissue and intravenous injection of umbilical cord blood-derived stem cells at different terms after diffuse-focal cerebral trauma revealed the best cerebroprotective effect on day 7 of posttraumatic period in animals receiving embryonic nervous tissue.
