    Description / Table of Contents: Zusammenfassung Rekombinante DNA, welche spezifisch mit einer repititiven DNA-Sequenz menschlicher Spezifität und mit einer repititiven DNA-Sequenz (pHY10) des Y-Chromosoms hybridisiert, wurde für die Identifizierung der menschlichen Spezies und für die Geschlechtsbestimmung degradierter DNA aus Blutspuren, Zahnpulpen und aus Knochenmark benutzt. Diese radioaktive Technik ermöglicht zuverlässige und empfindliche Bestimmung der menschlichen Spezies und des Geschlechts aus Blutspuren mit einem Alter von mehr als 80 Jahren. Weniger als ein blutspurenhaltiger Baumwollfaden von 0,5 cm Länge war ausreichend, um beide Tests durchzuführen. DNA aus relativ frischer Zahnpulpa und aus Knochenmark wurde eindeutig identifiziert. Der Identifikationstest auf die menschliche Spezies, welcher bis zu 0,3 Nanogramm DNA korrekt erkannte, war drei- bis fünfmal empfindlicher als der Geschlechtsbestimmungstest.
    Notes: Summary Recombinant DNA hybridizing specifically to a 300 nucleotide repeat DNA sequence (BLUR8) of human specificity and to human repeat DNA sequence (pHY10) on the Y chromosome was used for human identification and sex determination of degraded DNA samples of blood stains, dental pulp, and bone marrow. This radioactive technique enabled reliable and sensitive human and sex determination from blood stains that were more than 80 years old. Less than 1 piece of 0.5 cm length thread of blood stain was enough for both tests. DNA from relatively fresh dental pulp and bone marrow was clearly identified. The human identification test, which could recognize up to 0.3 ng DNA correctly, was 3 to 5 times more sensitive than the sex determination test.

    Notes: Summary In male and female dd-mice at 4, 7, and 14 weeks of age and in 7 and 14-week-old mice gonadectomized at 4 weeks of age, the number of osteoclasts and the number and size of bone resorption areas along the surface of bone trabeculae in the distal metaphysis of the femur were determined. Osteoclasts were counted at the light-microscopic level in paraffin sections of decalcified femora. The number and size of the bone resorption areas were examined by scanning electron microscopy of femora after removing organic material by means of KOH and NaOCl treatment. In untreated mice, the number of osteoclasts and the number and size of bone resorption areas showed no sex differences at 4 weeks of age but were larger in females than males at 7 and 14 weeks of age. In gonadectomized mice, the number of osteoclasts and the bone resorption areas increased in males and decreased in females. The results of the gonadectomy experiments suggest that bone resorption in young adult mice is stimulated by female sex hormone and inhibited by male sex hormone.
