體內(nèi)研究(In Vivo)    
Thymidine (500 mg/kg; i.p.; twice a day) completely reverses both Methotrexate- and Tomudex-induced deletion of both CD4Vβ8 and CD8Vβ8 T cells .
Medlife has not independently confirmed the accuracy of these methods. They are for reference only.
Animal Model:    8-12 weeks BALB/c mice
Dosage:    500 mg/kg
Administration:    i.p.; twice a day
Result:    Completely abrogates Methotrexate- and Tomudex-induced deletion of Vβ8 T cells after SEB injection.
