    Notes: Summary Alpha-fetoprotein (AFP)-producing capacity and some other properties of human hepatoma cell lines treated with chemotherapeutic agents, such as mitomycin C, Adriamycin, cisplatinum, and 5-fluorouracil were investigated. In the case of hepatoma cells that can be grown in culture following treatment with chemotherapeutic agents, their AFP-producing capacity was almost equal to that of untreated control cells with a few exceptions. On the other hand, in the case of similarly treated hepatoma cells that cannot be grown in culture, their AFP-producing capacity was quite different from that of untreated control cells. Under these conditions chromosomal and morphological aberrations were also observed in the treated cells. The present study shows that AFP-producing capacity of hepatoma cells can be changed by chemotherapeutic agents, probably through chromosomal mutation.

    Notes: Summary Eighteen barbituric acid (BA) derivatives and three structurally related chemicals (non-BA-derivatives) were tested for their potency in supporting survival of functional hepatocytes from adult rats in primary culture. Of the 18 BA derivatives, nine drugs showed excellent maintenance effect on hepatocyte survival and function. Although four BA derivatives were also effective, their potency was relatively lower. The remaining five BA derivatives and three structurally related chemicals exhibited no maintenance effect. Thus, a correlation was found between the BA derivative structure and the potency for supporting hepatocyte survival in primary culture. The dose response curves of hepatocyte survival were generally biphasic in shape, as a function of BA derivative concentration. The optimum concentrations for observing the morphological and biochemical effects of the BA derivatives differed from each other. The maintenance of hepatocytes was attained only in the continuous presence of the BA derivatives in the medium. The nine excellent BA derivatives efficiently prevented hepatocytes from morphological degeneration which was observed in the control cultures. The surviving hepatocytes in the presence of these BA derivatives showed higher albumin secretion and retained higher basal levels of tyrosine aminotransferase (TAT) activity for at least 2 weeks in primary culture, as compared with control. Furthermore, the addition of dexamethasone (10 µM) caused a 2- to 4-fold induction of TAT activity for at least 2 weeks in primary culture.
