    Notes: Abstract (1) An in vitro testis-superior spermatic nerve preparation was used to evaluate the effects of chemical agents applied in the bathing solution. Both directly evoked discharges and responses to algesic solutions [bradykinin (BK) 9×10−8 M, hypertonic saline 616 mM and high K+ solution 60 mM] of polymodal receptors were studied. (2) Prostaglandin (PG)-E2 (1.4×10−6–1.4×10−5 M) and serotonin (5-HT) (1.1×10−6 to 1.4×10−4 M) had only a weak excitatory effect. However, test responses to algesic substances were regularly greatly increased by PG-E2,-I2 and 5-HT. Concentrations of PG-E2 of 1.4×10−8 M or grealer augmented BK responses; higher concentrations and/or longer applications were needed to enhance responses to algesic salt solutions. Effective concentrations for the PGs and 5-HT were near those reported for inflamed tissues and exudate. (3) Aspirin (ASA) (5.5×10−4 M or greater, for more than 4 min) suppressed the responses to BK but not those evoked by hypertonic saline. The ASA effect on the BK response was largely restored by an addition of PG-E2. (4) Substance P also had a weak excitatory effect on some polymodal receptors, but no significant enhancement of the response to BK was noted. (5) These results further support a role of polymodal receptors in transmitting nociceptive information, of inflammatory origin.

    Notes: Summary Serum alpha-fetoprotein (AFP) concentrations increased promptly 2 days following a single injection of DL-ethionine (ethionine) in adult female rats. Continuous elevation of serum AFP was also observed on feeding a diet containing 1% ethionine for at least 2–3 weeks. A rise of serum AFP was not found if the diet was supplemented with 2.8% methionine. Furthermore, in rats fed on 1% ethionine for 2 weeks, dietary change to the laboratory chow supplemented with and without 2.8% methionine produced a decrease of increased serum AFP levels.

    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.
