Notes: The mandibular incisor of the 16 day embryonic mouse was divided into three visibly equal thirds; each third was explanted in vitro to test its capabilities for independent development. Ameloblasts and odontoblasts, present in the distal third at the time of isolation, fail to continue their differentiation. This third flattens, and the tissues become disorganized. Grouping several distal thirds in a single culture did not promote tissue differentiation. The embryonic proximal third remains cohesive The tissues differentiate; both ameloblasts and odontoblasts deposit extracellular matrix. Approximately half of the cultures of the intermediate third show differentiated odontoblasts and extracellular matrix after 11 culture days. Measurements of the volume changes of ameloblasts, odontoblasts, and general mesenchyme were taken over the first six culture days for each third of the rudiment. The volume changes recorded, and the counts of mitotic figures reflect the developmental behavior of each fraction of the rudiment.

Description / Table of Contents: Carbon-13 NMR Investigation of Taxin B from Taxus baccata L.Use of carbon-13 NMR involving polarization transfer experiments (DEPT), carbon-proton and proton-proton correlation spectroscopy proved the structures of the main alkaloid from Taxus baccata L. (taxin B) and of its more stable diacetyl derivative. The same structures have been assigned by other authors to a hypothetical taxin-I and its diacetyl derivative.

Notes: Durch Anwendung der 13C-NMR-Spektroskopie (DEPT) und spezieller NMR-Techniken (CH- und HH-COSY) bei Taxin B, dem nativen Hauptalkaloid aus Taxus baccata, sowie bei dem stabileren Diacetyltaxin B wurden die gleichen Strukturformeln ermittelt, wie sie von anderen Autoren dem hypothetischen Taxin-I und seinem Diacetat zugeordnet wurden.
