Abstract
A comparative analysis of leukocyte types number in rat blood smears at the craniocerebral (CCH 32°C) and immersion (IH 27°C) hypothermia, surface rhythmic cold exposures (RCEs 5°C) and whole body cryostimulation (WBC –120°C), as well as in 24 hrs revealed the leukocytosis (at IH and 24 hrs after CCH and IH), leukopenia (at CCH, RCEs and 24 hrs after WBC), lymphopenia, an increase in band and segmented cells (under all conditions except IH) and eosinophils (only at CCH and 24 hrs after WBC). Plasmatic cells (except WBC), polychromatophilic and immature cells (immediately and in 24 hrs after CCH and IH), cytoplasm plasmatization in some leukocytes (24 hrs after CCH and IH) were observed. Leukocyte indices showed the immunoreactivity disorder, decreased allergization, activation of cell immunity, nonspecific cell protection and inflammation (under all conditions, except IH), as well as microphages (at WBC and 24 hrs after CCH and IH), an effector component of immunity (at CCH, RCEs and 24 hrs after WBC), immediatetype hypersensitivity responses (except at CCH and 24 hrs after WBC). The nuclear shift index was increased (except RCEs and WBC). The adaptation index was raised only at IH. Probl Cryobiol Cryomed 2018; 28(4): 293-310
Highlights
A comparative analysis of leukocyte populations in rat blood smears at the craniocerebral (CCH 32°C) and immersion (IH 27°C) hypothermia, superficial rhythmic cold exposures (RCEs 5°C) and whole body cryostimulation (WBC –120°C), as well as in 24 hrs post-effect revealed the leukocytosis, leukopenia, lymphopenia, an increase in band and segmented cells and eosinophils
During the craniocerebral hypothermia (CCH) there is a forced cooling of cerebral structures, resulting in appearance of a temperature gradient between the brain and the rest of a body
The CCH contributes to the transition of the organism to a new, more ‘economic’ functional level
