    Description / Table of Contents: Abstract In the United States of America, the nasometer was developed by Fletcher as an objective method for measuring nasality. There are no accepted normal values for comparable test materials regarding the German language. The aim of this study was the examination of the auditively normal nasality of Saxon-speaking people with the nasometer. The nasalance of 51 healthy Saxon-speaking test persons with auditively normal nasality was measured with a model 6200 nasometer (Kay-Elemetrics, U.S.A.). The text materials used were the vowels “a”, “e”, “i”, “o”, and “u”, the sentences “Die Schokolade ist sehr lecker” (“The chocolate is very tasty”) and “Nenne meine Mama Mimi” (“Name my mama Mimi”), and the texts of “North wind and sun”, “A children's birthday”, and an arbitrary selection from Strittmatter. The mean nasalance for the vowels was 17.7%, for the sentence containing no nasal sounds 13.0%, and for the sentence containing many nasal sounds 67.2%. The mean value of the texts was 33–41%. The results for the texts agreed well with the results of Reuter (1997), who examined people from the state of Brandenburg. A range from 20% to 55% is suggested as the normal value for nasalance in the German-speaking area.
    Notes: Zusammenfassung In den USA wurde von Fletcher das Nasometer als objektive Nasalitätsmessmethode entwickelt. Für das Nasometer bestehen im deutschsprachigen Raum für vergleichbare Testmaterialien keine anerkannten Normwerte. Anliegen der vorliegenden Studie ist die Untersuchung der auditiv normalen Nasalität im sächsischen Sprachraum mit Hilfe des Nasometers. Es wurden die Nasalanzwerte von 51 gesunden Testpersonen mit auditiv normaler Nasalität aus dem sächsischen Sprachraum mit dem Nasometer (Modell 6200, Fa. Kay-Elemetrics, USA) bestimmt. Als Testmaterialien wurden die Vokale “a”, “e”, “i”, “o”, “u”, die Sätze “Die Schokolade ist sehr lecker” und “Nenne meine Mama Mimi”, sowie die Texte “Nordwind und Sonne”, “Ein Kindergeburtstag” und ein Auszug aus dem Text “Der große Gesang” von Strittmatter benutzt. Der Mittelwert der Nasalanz für den keine Nasallaute enthaltenden Satz liegt bei 13,0%, für Vokale bei 17,7%. Der mittlere Nasalanzwert beträgt für den viele Nasale enthaltenden Prüfsatz 67,2%. Der Mittelwert der Texte liegt bei 33–41%. Die Ergebnisse für die Texte stimmen gut mit den Ergebnissen von Reuter aus dem brandenburgischen Sprachraum überein. Als Normwert für die normale Nasalanz im deutschsprachigen Raum wird für gemischte Texte der Bereich von 20–55% vorgeschlagen.

    Notes: A transgenic mouse strain derived from embryonic stem (ES) cells infected with multiple copies of a retroviral vector carries a recessive insertional mutation resulting in prenatal lethality. A detailed histological analysis of developing embryos has shown that the mutation results in hyperplasia of both embryonic and extraembryonic ectoderm and failure of mesoderm formation in the egg cylinder stage embryo. The number of cells in each lineage of normal and mutant embryos was estimated using stereological analysis of serial sections taken from implantation sites. We observed a 2-fold increase in the number of embryonic ectoderm cells in mutant embryos at 7.5 days postcoitum (dpc). In addition, we found that mutant embryonic ectoderm cells are only 0.6 times as large as normal cells. The number of extraembryonic ectoderm cells in mutant embryos at 7.5 dpc is also increased, by almost 4-fold. Mutant extraembryonic ectoderm cells are also smaller than normal, being only two-thirds the size of wild-type cells. The mutant phenotype suggests that the gene identified by this insertional mutation plays an important role in the growth control of early embryonic lineages. © 1992 Wiley-Liss, Inc.
