    Notes: Abstract Gravid Sprague-Dawley-derived rats were injected SC twice daily with either 20 or 40 mg/kg pentobarbital sodium (PT), sodium phenobarbital (PH), or the same volume of the saline vehicle on days 9–21 of pregnancy. Pair-feeding was employed. Vital, developmental, and activity measures were obtained on the neonates and locomotor activity was measured from 3–10 months of age. Avoidance was measured sequentially in a shuttle box, and in an operant chamber beginning at 3 months of age. The PH-80 dams gained less weight over the gestational period, and PH-80 and PH-40 offspring had more neonatal deaths. These male offspring were hyperactive at maturity, and PH-80 rats were initially slower to escape experimenter-initiated shock. PT exposure caused transient neonatal and juvenile hyperactivity. PT rats performed more poorly on both the conditioned avoidance and Sidman shock schedules, and had significantly lower brain: body weight ratios at 1 year of age. All four drug groups outperformed the saline offspring on subject-initiated shock schedules (punishment). Sex of offspring was determined on postnatal day 4 and the sex ratio was shifted towards male births with both drugs relative to controls.

    Kinetics and mechanism for the reactions of H atoms with CH3SH and C2H5SH (1988)

    Notes: A kinetic study of the reactions of H atoms with CH3SH and C2H5SH has been carried out at 298 K by the discharge flow technique with EPR and mass spectrometric analysis of the species. The pressure was 1 torr. It was found: k1 = (2.20 ± 0.20) × 10-12 for the reaction H + CH3SH (1) and k2 = (2.40 ± 0.16) × 10-12 for the reaction H + C2H5SH (2). Units are cm3 molecule-1 s-1. A mass spectrometric analysis of the reaction products and a computer simulation of the reacting systems have shown that reaction (1) proceeds through two mechanisms leading to the formation of CH3S + H2 (1a) and CH3 + H2S (1b).

    Kinetic study for the reactions of OH radicals with dimethylsulfide, diethylsulfide, tetrahydrothiophene, and thiophene (1985)
    New York, NY : Wiley-Blackwell

    Topics: Chemistry and Pharmacology
    Notes: The reactions of OH radicals with dimethylsulfide (DMS) diethylsulfide (DES), tetrahydrothiophene (THT), and thiophene have been studied at room temperature for DES and THT, at 273, 293, and 318 K for DMS, and at 293 and 318 K for thiophene by the discharge flow EPR technique in a halocarbon wax coated reactor. The following rate constants were obtained at room temperature. For the reaction OH + DMS (1), a very low temperature dependence was noticed.Some additional results concerning the mass spectrometric analysis of the products are also reported.
