    Medazepam and the driving ability of anxious patients (1977)

    Notes: Abstract A double blind crossover trial of Medazepam was carried out in 14 anxious hospital patients. The mean self-adjusted dosage was 16.5 mg daily. The active drug was no more effective than placebo in relieving anxiety, which was rated both clinically and by the Middlesex Health Questionnaire (M.H.Q.) (Crown and Crips, 1970). This may have been because the dose was relatively low for chronically anxious hospital patients. Even this dosage caused significantly higher scores on the M.H.Q. scale for depression. Braking and driving simulator tests were not adversely affected by Medazepam. In real driving conditions those taking the drug made significantly more technical, but not dangerous, errors. Pulse and blood pressure also were not affected.

    Observations on the fine structure of propylthiouracil-induced “brown degeneration” in the zona reticularis of mouse adrenal cortexThis research was supported by NIH grants GM 00459 and NS 00690, and the Veterans Administration Hospital, Tampa, Florida. (1975)

    Notes: Propylthiouracil (6-propyl-2-thiouracil), an anti-thyroid agent, was fed to mice in a concentration equal to 0.1% of their diet for periods of 10 and 15 weeks. The cells of the inner zone of the adrenal cortex were examined with the electron microscope. In animals receiving propylthiouracil for ten weeks mitochondria were altered and the smooth endoplasmic reticulum (SER) showed a marked focal proliferation. In contrast to control animals rough endoplasmic reticulum was abundant and was frequently associated with the hyperplastic SER. After 15 weeks these alterations were no longer present but had been replaced by a spectrum of “brown degeneration.” The less affected cells were characterized by increased numbers of liposomes and lysosomes and the more affected cells by liposomal and mitochondrial degeneration. These observations emphasize that “brown degeneration” is a true degenerative process and not a spontaneous proliferation of ceroid pigment. It is suggested that the changes described may be directly related to an alteration in cholesterol metabolism.

    A comparative morphometric analysis of the effects of thyroxine and acth on the zona fasciculata of rat adrenal cortexAided by NIH Grant 5 S01 RR05749-02 (1976)
    New York, NY [u.a.] : Wiley-Blackwell

    Notes: The effects of thyroxine and ACTH on the ultrastructure of cells of the adrenal zona fasciculata were studied by morphometric analysis and compared by two-way analysis of variance. The results indicate that the effects of thyroxine and ACTH are different and independent. The statistically significant differences in effect of thyroxine and ACTH are: thyroxine causes an increase in the volume fraction of mitochondria and a decrease in the volume fraction of endoplasmic reticulum independent of ACTH; thyroxine causes a decrease in surface density of mitochondria and endoplasmic reticulum in the absence of ACTH, but in the presence of ACTH this effect is moderated by an interaction of thyroxine and ACTH. There were no statistically significant effects of either thyroxine or ACTH on volume fraction or surface density of liposomes.

    Elemental X-ray mapping of cementitious phases using an energy-dispersive spectrometer in the scanning electron microscope (1978)

    Notes: Elemental X-Ray mappings on Portland cement clinkers have been obtained using a scaning electron microscope-energy dispersive system (SEM-EDS). Using this method, elemental mapping of the major constituents of cement (Ca, Si, Al, Fe) can be generated in as little as 300 s, while the minor constituents(〈10%) Such as Na, Mg, P, S, K yield poorer contrast mappings. The technique used and the resultant mappings obtained are discussed.
