CAT and myeloid sarcoma: Analyzing previous reports on the effect of whole-body cryotherapy (WBC) in MS patients, the authors found that WBC can increase patients’ TAS (total antioxidant status) and may play an important role in the process of activating antioxidant systems in MS patients, but no significant changes in antioxidant enzymes (catalase, glutathione peroxidase) were detected, except for in superoxide dismutase, when the number of WBC sessions was increased to 30, suggesting that different cooling interventions may influence the changes seen in antioxidant capacity [4,5,6,7,8,9].
