Methotrexate disodium markedly decreases white blood cells, thymic and splenic lymphocytes at dose ≥5mg/kg. However, there is a significant difference between the treatment plus control group and the model group (p<0.01). The combination of grape seed proanthocyanidins and Siberian ginseng eleutherosides obviously diminishes the effects of Methotrexate exposure on indices of thymus and spleens in mice. 体内研究 Methotrexate (MTX) disodium (2mg/kg; i.p.; once in a week for 5 weeks) is effective in Freund's complete adjuvant-induced arthritis. The combination of Methotrexate disodium (1mg/kg; i.p.; once in a week for 5 weeks) and Curcumin (30mg/kg and 100 mg/kg, thrice a week for 5 weeks; i.p.) shows a significant anti-arthritic action and protection from hematological toxicity. |
