    Notes: Abstract Electrolytic conductivities of eight simple 1∶1 electrolytes have been measured in dilute solutions of 2-cyanopyridine (2CNP) at 30°. Infinite dilution mobilities and association constants were calculated using the Fuoss-Hsia equation. With the exception of LiCF3SO3 all salts show very little association, consistent with the very high dielectric constant of 2CNP. The weak association which does occur is attributed to weak ion-solvent interactions. No evidence was found for triple ion formation. Conductivities of concentrated solutions of LiAsF6 in 2CNP increase slowly with concentration reaching a maximum at a concentration of around 0.65 mol-dm−3. These conductances are slightly lower than those in propylene carbonate which has a lower dielectric constant and a higher viscosity. Conductivities of concentrated LiAsF6 solutions in 2CNP mixtures with acetonitrile vary monotonically, consistent with solution viscosities, and show no sign of the maximum commonly observed in mixed organic solvents.

    New strategies in marrow purging for breast cancer patients receiving high-dose chemotherapy with autologous bone marrow transplantation (1993)

    Notes: Summary High-dose chemotherapy and autologous bone marrow transplantation (ABMT) are commonly used to treat selected patients with high-risk breast cancer. A limitation of ABMT is that clonogenic cancer cells could be collected with the bone marrow and produce a relapse of disease when reinfused into patients. Purging the marrowex vivo may eliminate the tumor cells, but it can also delay engraftment. We employed two different purging methods whereby breast cancer cells were depleted without delaying engraftment. The addition of WR-2721 (amifostine) to 4-hydroperoxycyclophosphamide (4-HC) reduced the time to engraftment by 10 days compared with marrow purged with 4-HC alone (26 versus 37 days, respectively). The positive selection of CD34+ hematopoietic progenitors produced engraftment within 21 days. The use of granulocyte colony-stimulating factor (G-CSF) accelerated the engraftment time of CD34+ hematopoietic progenitors to 11 days.

    Pharmacokinetic/pharmacodynamic interactions of intensive cyclophosphamide, cisplatin, and BCNU in patients with breast cancer (1993)

    Notes: Summary Combinations of alkylating agents in intensive doses with autologous hematopoietic cell support (AHCS) are commonly used to treat advanced, solid tumors. Relatively little is known about the pharmacokinetic or pharmacodynamic aspects of their use. The cyclophosphamide, cisplatin, and BCNU (CPA/cDDP/BCNU) regimen is often used in patients with breast cancer. In these individuals, the blood levels of BCNU vary by more than tenfold. In rats given BCNU, the blood level variability is associated with cisplatin pretreatment, and mean levels are much higher than those that occur when cisplatin pretreatment is omitted. These observations suggest that a major elimination pathway for BCNU is metabolic and is subject to cisplatin disruption. Between 30–50% of patients receiving the CPA/cDDP/BCNU regimen experience a steroid-responsive pulmonary injury that can be fatal if untreated. Blood levels of BCNU are positively correlated with the risk of pulmonary injury in these patients. Others have demonstrated that blood levels of CPA can be inversely correlated with the likelihood of cardiac toxicity and 2-year, relapse-free survival in patients with breast cancer. Emerging data suggest that circulating drug levels, rather than the calculated dose, best explain the variability of outcome in patients treated with combination alkylating agents and AHCS.
