    Notes: Summary The influence of adrenalectomy on the amount of “Gomori-positive” neurosecretory material in the outer layer of the median eminence and in the supraoptico-hypophysial system was studied in normal Long-Evans rats and in Long-Evans rats heterozygous and homozygous for hypothalamic diabetes insipidus. In all non-adrenalectomized rats very few “Gomori-positive” granules were found in the outer median eminence layer. After adrenalectomy the amount of the granules increased markedly in normal Long-Evans rats and only slightly in Long-Evans rats heterozygous for diabetes insipidus. However, no augmentation of the granules occurred in homozygous diabetes insipidus rats. The amount of “Gomori-positive” substances demonstrable in the supraoptic and paraventricular nuclei, in the inner layer of the median eminence, and in the neural lobe of the hypophysis was less in rats heterozygous for diabetes insipidus than in normal Long-Evans rats and the smallest in homozygous diabetes insipidus rats. No differences in the amounts of the substances were observed between adrenalectomized and non-adrenalectomized animals. The findings suggest that the “Gomori-positive” granules occurring in the outer layer of the median eminence of adrenalectomized rats are of similar origin as those of the supraoptico-hypophysial system and represent a vasopressin-neurophysin-complex. The results support the concept that vasopressin is involved in the regulation of ACTH release.

    Gomori-positive elementary granules in inner and outer layer of the infundibulum (1975)

    Notes: Summary With the gallocyanine technique (Wittkowski, Bock and Franken, 1970) Gomori-positive substances of the infundibulum can be stained for light- and electron-microscopic examination. In various mammalian species, the size of Gomori-positive elementary granules in the outer layer is markedly different from that in the inner layer of the infundibulum. In general, the granules of the outer layer have less then half the diameter of those of the inner layer. In birds and fish, however, only small differences were found between the granules of both layers. The significance of the results is discussed.

    A lod score method for detecting linkage on the X chromosome between a marker locus and a major gene locus for a quantitative character (1979)

    Notes: Abstract A sequential lod-score method is proposed for detecting linkage on the X chromosome between a marker locus and the locus of a major gene influencing a quantitative trait. The method uses information from sons of doubly heterozygous mothers. The average number of families required to detect linkage is substantially less than that of the fixed sample-size method proposed by Hill.
