Miriplatin is a novel lipophilic platinum complex developed to treat hepatocellular carcinoma (HCC). Although HCC patients frequently have coexisting severe liver cirrhosis, there is no prospective data regarding clinical toxicity of miriplatin in HCC patients with severe cirrhosis. We retrospectively evaluated the safety and efficacy of transcatheter arterial chemotherapy with miriplatin in 34 HCC patients with severe liver cirrhosis (Child-Pugh grade B). An anti-tumor effect of complete response was achieved in 8 of 34 patients and no serious adverse events were observed. These results suggested that transcatheter arterial chemotherapy with miriplatin can be used safety for HCC patients with Child-Pugh B liver cirrhosis.

The performance of the ion thruster depends on the discharge performance and the beam extraction, the former of which is significantly effected by the electron property such as density and energy, since ions are produced by ionization collisions between neutral atoms and electrons. In the microwave ion thruster, the discharge owes to the electron cyclotron resonance (ECR). Thus, the electron phenomenon in the microwave discharge chamber was numerically investigated by the particle simulation method. In our model, the electromagnetic wave is polarized circularly and propagates in the axial direction and electrons are moved in the microwave and static magnetic fields, colliding with neutral particles. Collision processes are taken into account by the Monte Carlo method. This simulation results show that some electrons can be heated enough to cause ionization collisions and that the density and energy distributions are peculiar to the microwave ion thrusters.

To further improve therapeutic effect on chronic hepatitis C, we have administered NS3 inhibitor and NS5A inhibitor together, and examined effects of early antiviral agent therapy. The subjects were five cases where interferon is ineffective (null responders). The NS5A and NS3 inhibitors are oral drugs and were daily administered for 24 weeks. Figure 1 shows time-dependent change of the number of viruses after the therapy started, and rapid decrease of viruses is recognized. Within 12 hours, HCV-RNA decreased by more than 2 log IU/ml in every patient. Two patients became negative for the virus by the 15th day after the therapy started. Furthermore, 80% of cases by the 28th day and all the cases by the 56th day became negative. The new therapy has manifested excellent early antiviral effect.
