The experiment was conducted on female Wistar rats which were placed within the experimental and control groups of two dosage models: model (A) - cladribine being administered in a daily dose of 0.1 mg/kg by weight for 7 days, and model (B) - cladribine being administered in a daily dose of 0.07 mg/kg by weight in 3 cycles of 6 days with 5 weeks break.
