    Notes: Abstract Androgenesis is a potentially valuable technique for recovering fish from gene banks composed of cryopreserved sperm, developing inbred lines, and analyzing patterns of inheritance. The procedure for producing diploid organisms whose nuclear DNA is wholly of paternal origin is dependent on: (1) the denucleation of “host” eggs, and (2) the inhibition of the first mitotic division in order to double the haploid sperm chromosome complement following fertilization of host eggs. Denucleation of tilapia (Oreochromis niloticus L.) eggs was carried out using UV irradiation. Treatment durations of 5–8 min (total dose of 450–720 J/m2) produced acceptable yields of viable denucleated eggs [22.9±1.6% (±SE) of controls] as estimated by the survival of haploid androgenetic tilapia to 48 h post-fertilization. Successful mitotic inhibition was accomplished using a heat-shock of 42.5 °C for 3–4 min, applied at 2.5-min intervals from 22.5 to 30 min post-fertilization (mpf). The mean survival of androgenetic diploid fish to yolk-sac absorption for treatment groups varied from 0.4% to 5.3%, relative to the controls. Differences in the suceptibility of eggs from different females to UV irradiation were a significant factor in the overall yield of androgenetic diploids. Paternal effects did not significantly influence the androgenetic yield, suggesting that individual males would not be selected against. For comparative purposes mitotic gynogenetic “mitogyne” diploids were produced from UV-irradiated sperm. Mean survival to yolk-sac absorption varied from 0.5% to 10.64%, relative to controls. Similar optima for androgenetic and gynogenetic induction were found in the period 25–27.5 mpf (minutes post-fertilization). Induction treatments would appear to be operating on the same developmental events in both these techniques, and the results suggest that the UV irradiations used do relatively little damage to the eggs beyond nuclear inactivation. The results indicate that the production of androgenetic O. niloticus is possible on a consistent basis and that the application of this technique may be useful in quantitative and conservation genetics.

    Notes: Summary The pharmacokinetics of bisantrene, 9,10-anthracenedicarboxaldehyde bis ((4,5-dihydro-1 H-imidazol-2-yl) hydrazone) dihydrochloride were evaluated during a Phase I clinical investigation. Bisantrene at doses of 20 to 280 mg/m2 was administered by variable infusion rates to nine patients with advanced metastatic cancer. Bisantrene's plasma clearance followed a triexponential pattern with a harmonic mean terminal half-life (t1/2 γ) of 26 h. The steady state volume of distribution (Vd ss ) was large, averaging 627 l/m2. Plasma clearance averaged 42.6±6.7 l/h/m2. The cumulative urinary excretion of bisantrene was 3.6±1.6% at 48 h.

    Anaphylactoid reactions associated with bisantrene infusions (1983)
    Springer
    Investigational new drugs 1 (1983), S. 85-88 
    Details
    ISSN: 1573-0646
    Keywords: bisantrene ; hypersensitivity ; histamine release
    Source: Springer Online Journal Archives 1860-2000
    Topics: Chemistry and Pharmacology , Medicine
    Notes: Summary Nine of ninety-three patients receiving Bisantrene on an every three week schedule developed an anaphylactoid reaction with a variety of symptoms. Most reactions occurred in patients who had multiple exposures to Bisantrene. Investigatiors utilizing Bisantrene in ongoing clinical trials should be aware of this life threatening toxicity.
