    Notizen: Summary In a cytophysiological study it was investigated whether in juvenile trout gonadal steroids stimulate the gonadotropic (GTH)-cells directly or indirectly via the brain. Pituitaries of donor animals were transplanted into the caudal musculature of testosterone-treated and non-testosterone-treated host fish. Testosterone treatment caused an increase in GTH-content in the in situ pituitaries and in the grafts. Accordingly, the gonadotrops displayed ultrastructural changes such as the appearance of well-developed Golgi systems and large globules. The stimulation of the morphological development of gonadotrops and of synthesis and storage of GTH in the allografted pituitaries indicates that testosterone affects the GTH-cells directly. In untreated juvenile trout the gonadotropin content of the pituitary and the gonadotropin concentration in the plasma vary with the time of year. This variation and the role of testosterone and gonadotropin-releasing hormone on the release of GTH are discussed.

    Use of cimetidine; parallels and discrepancies between the views of drug regulatory agencies and practicing physicians (1983)
    Springer
    European journal of clinical pharmacology 25 (1983), S. 601-607

    Notizen: Summary The use of cimetidine in general practice was studied in relation to the guidelines approved by the Dutch National Drug Regulatory Agency (DRA). National and regional figures showed that the frequency with which cimetidine was prescribed in general practice was greater than could be explained on the basis of approved indications alone. Analysis of its employment in 14 hypothetical cases suggested however, that general practitioners in The Netherlands chose their indications for cimetidine and the duration of cimetidine treatment according to the guidelines for its use approved by the DRA; only 12.7% of the prescriptions related to indications that had not been approved in The Netherlands, the most prominent finding being the case of a possible gastric carcinoma. It was estimated that less than half of all cimetidine prescriptions in general practice will be issued for indications approved by the Dutch DRA. Some discrepancy exists with regard to the dose employed; contrary to the recommendations of the DRA, the dose chosen varied little from indication to indication.

    A quantitative description of the growth of Saccharomyces cerevisiae CBS 426 on a mixed substrate of glucose and ethanol (1980)
    New York, NY [u.a.] : Wiley-Blackwell
    Biotechnology and Bioengineering 22 (1980), S. 2031-2043 
    Details
    ISSN: 0006-3592
    Schlagwort(e): Chemistry ; Biochemistry and Biotechnology
    Quelle: Wiley InterScience Backfile Collection 1832-2000
    Thema: Biologie , Werkstoffwissenschaften, Fertigungsverfahren, Fertigung
    Notizen: Saccharomyces cerevisiae CBS 426 was grown aerobically in continuous culture with a mixture of glucose and ethanol as the carbon source. The flows of biomass, glucose, ethanol, oxygen, and carbon dioxide were measured. A model for growth with two substrates was derived. Application of this model to the above-mentioned system yielded values for YATP and P/O. The joint confidence regions for these parameters were calculated. The relevance to industrial production of bakers' yeast is discussed.
