Normal fetuses 14 to 17 days old were obtained from female Wistar rats. The palates have been studied, after dissection, by scanning electron microscopy. Palatal closure is achieved, in the median and posterior region, by the elevation of the lateral palatine processus from a ventro-medial to a horizontal position; immediately after the horizontalization, they adhere to each other. Rostrally naso-palatine canal closure takes place later; it results from an epithelial and mesenchymal outgrowth under the nasal septum. The mutual adhesivity of the free edges of the lateral processes is noticeable. The pattern of the fusion surface has been considered, elements such as exfoliated cells, filopodes and microvilli are present. Their contribution to the adherence phenomenon is discussed. [less ▲]

Etude au microscope electronique a balayage et a transmission de l'epithelium amniotique chez la ratte en fin de gestation.

The pattern of the amniotic epithelium during the eight last days of pregnancy is described with the aid of scanning and transmission microscopy. A flattening of the cells appears near the term. Their area becomes progressively greater increasing their contact surface with the amniotic fluid. Simultaneaously, their microvilli become more numerous. During the 20th, the 21st and the 22nd days of pregnancy, we observed cytoplasmic processes emanating from the base of the cell interrupting the basal membrane and entering the underlying connective substance. No evidence of cell degeneration was seen. [less ▲]

Chick embryo nerve cells from the lumbo-sacral spinal cord have been isolated by trypsinisation and cultivated in Rose chambers on polylysine-L as a substrate. The cells are analysed by scanning electron microscopy. The mode of adherence of these cells to the substrate and the modifications of the surface of the neuroblasts during their transformation into neurocytes are studied. [less ▲]

Strychnofoline is a phenolic alkaloid isolated from leaves of Strychnos usambarensis. The crystals of the complex Strychnofoline-Ethanol are monoclinic. the crystal structure has been solvad by direct methods. The configuration determined by biogenetic arguments is 3S?4R?7S?15S?17S?20R. This is the first oxindole alkaloid found in a Strychnos species. [less ▲]

The report first analyses the causes and consequences of the recent de-urbanisation of industrial activities. On account of the problems created by this movement, the survey then puts forward new solutions that aim for a better integration of industrial concerns. These proposals deal mainly with the types of industries that should be maintained or established as well as the terms and conditions of integration. In this connection, it seems impera¬tive to work out a new planning policy for urban space where the renovated secondary sector would find its place due to new formulas such as vertical industrial structures, individual buildings with an urbanised facade and small industrial estates.
