TL;DR: The greatest effectiveness was observed in the MFD + MBV + CDDP group with tumor inhibition rate of 100%, in which eight tumors disappeared, and the AFP level was decreased as the tumor size reduced.
Abstract: A comparative study of multiple modalities of multiple fractions of external radiation per day (MFD), routine radiation (RD), cisplatin (CDDP), mixed bacterial vaccine (MBV), MFD + CDDP. MFD + MBV, MFD + CDDP + MBV on nude mice bearing human hepatocellular carcinoma (HCC) were investigated. The tumor size and serum alpha fetoprotein (AFP) level were measured. The results showed that the tumor inhibition rates were 97%, 94%, 79%, 2% for the MFD, RD, CDDP, and MBV groups, respectively. No tumor disappeared (complete regression) in single modality groups. When MFD was used in combination with CDDP and/or MBV, the tumor cure rates were remarkably increased. The tumor inhibition rate was 99% in the MFD + MBV group, in which two tumors disappeared, 99% in the MFD + CDDP group as well, in which five tumors disappeared. The greatest effectiveness was observed in the MFD + MBV + CDDP group with tumor inhibition rate of 100%, in which eight tumors disappeared. In all these groups, the AFP level was decreased as the tumor size reduced. Preliminary clinical results were satisfactory, the decrease of the serum AFP level and shrinkage of tumor were observed in 88% (7/8) and 91% (10/11) of patients, respectively.

TL;DR: In this paper, the onset of melting in a class of simple metals is considered for an applied heat flux q_0=h_0/t~(1/2) at the boundary.
Abstract: The onset of melting in a class of simple metals is considered for an applied heat flux q_0=h_0/t~(1/2) at the boundary. Reduction of the nonlinear problem to a linear canonical form is obtained by a reciprocal transformation. Bounds are obtained on h_0 for melting to occur.

TL;DR: The result indicates that the transplantable nude mice-human HCC model is acceptable for targeting study of HCC and five kinds of substances with affinity to HCC were studied in this animal model.
Abstract: Fifty-three nude mice bearing human HCC were used for targeting study of HCC using 131I-antihuman HCC isoferritin IgG. Of these mice, 17 were used for radioimaging with 131I-labeled IgG, 131I-labeled albumin and 131NaI. In labeled IgG group, all tumors were positively visualized by gamma camera with the best imaging on the 7th day after injection of labeled IgG (200 microCi, ip), the tumor/liver radioactivity ratio being 2.7. The dose of tumor radioactivity at the 7th day was 7-10 times higher than that in labeled albumin group. Thirty-six mice were used for the study of radioimmunotherapy with 131I-labeled IgG, 131NaI and IgG (n = 9, 300 microCi/50 micrograms, ip). The tumor inhibition rate in the labeled IgG group at 4th week after treatment was significantly higher than those of the other groups (81%, 60% and 18%, respectively, P less than 0.05). Tumor cell DNA analysis showed that the tumor cells were inhibited in S stage of the cell cycle. In the same way, five kinds of substances with affinity to HCC were studied in this animal model. The result indicates that the transplantable nude mice-human HCC model is acceptable for targeting study of HCC.
