RESUMEN
The hematological effects of Sokeikakketsu-to, Yokuinin-to, Keisi-ka-jutsubsu-to, Eppi-ka-jutsu-to, and Sairei-to observed on the AA rats were investigated. The time course of blood count and albumin, sialic acid and acid-soluble glycoprotein in the serum whs. were measured. Sokeikakketsu-to had the strongest anti-inflammatory effect on the improvement of Inflammatory Index Substances, platelets, and the Arthritis Score for changes in synovitis. Yokuinin-to was also effective. When these Kampo medicines were administered in the early stages of AA, Sokeikakketsu-to improved the AA signficantly. The results may suggest that Sokeikakketsu-to works for the control of autoimmunity. On the other hand, Keisi-ka-jutsubu-to aggravated the AA when it was administered in the early stages of the AA.
