Hot water-extracts prepared from Cordyceps militaris of silkworm pupa (CMP) or Cordyceps militaris of silkworm larva (CML) were tested for tumor growth inhibitory and immunomodulatory activities in ICR mice bearing sarcoma-180 cells solid tumor, and compared with those of the known compound, cordycepin, found in Cordyceps militaris. Mice were subcutaneously injected with sarcoma-180 cells, and i.p. injected with either saline (Control), 50 mg/kg or 100 mg/kg of CMP (CMP50 or CMP100, respectively), or CML (CML50 or CML100, respectively), or 1 or 2 mg/kg of cordycepin (C1 or C2, respectively) for 10 days. Mice injected with CMP50 or CMP100 showed a 47.3% or 57.6% inhibition in the solid tumor growth (P<0.05), while those injected with CML50 or CML100 exhibited a 35.5% or 37.1% reduction (p<0.05) in solid tumor size compared to the value for control mice treated with saline. Animals injected with corcycepin showed a 26∼30% inhibition in the solid tumor growth (P<0.05). Mice bearing solid tumor and injected with CMP or CML showed a significantly increased thymus weight (38∼44% increase), lymphocyte percentages of CD4+ T-cell, CD8+ T-cell, and NK-cell (63∼110% increase) in the spleen, and interleukin-2 excretion (33∼51% increase) by the isolated splenocytes compared to those in control mice (p<0.05). These results indicate that the anti-tumor activity of hot water extracts of Cordyceps militaris, raised on both silkworm pupa and silkworm larva, appears to be associated with their immunomodulatory activity, and these activities found in Cordyceps militaris are superior to those for the single compound, cordycepin.

Purpose: The purpose of this study was to evaluate the efficiency of treatment of living-related liver transplantation (LRLT) with the parental heterozygote carrier graft in children with Wilson disease. Methods: We retrospectively evaluated 7 children with Wilson disease who had received liver transplantation from 1994 to 2002 at Asan Medical Center. All the donors were parental. Liver functions, Kayser-Fleischer ring, and other factors regarding to copper metabolism were analyzed. Results: Of the 7 children, 5 had fulminant hepatitis and 2 had decompensated liver cirrhosis irresponsive to medical therapy. All donors being parental, all grafts came to be heterozygote carrier grafts. Survival rate was 100% in those 7 children, 87% in all children with liver transplantation in the same period, and 84% in children with non-metabolic liver disease. After liver transplantation, all 7 children could stop low copper diet and penicillamine therapy and their AST, total bilirubin and prothrombin time were recovered to normal. After liver transplantation, ceruloplasmin and serum copper levels were also recovered to normal. A marked reduction in 24 hr-urinary copper excretion was observed in all recipients after transplantation. During follow-up, Kayser-Fleischer rings resolved completely after LRLT in 5 children and partially in 1 child. Conclusion: We concluded that living-related liver tranplantation in children with Wilson disease with parental heterozygote carrier graft is an effective treatment modality.
