[Determining of new karyotypes: value of a statistical method].

For the authors, Ectemnorrhininae (coleoptera, curculionidae) from Southern Indian Ocean islands constitute the subject of systematic karyological studies, in order to get further information as to the phylogeny of this group of insects. A previous study had been carried out about 3 different species, Ectemnorrhinus drygalskii, E. viridis and Dusmoecetes richtersi, through direct observation of the only few mitotic metaphase plates, completely isolated from each other, which could be found in adult testis squashes.

Hepatosplenography by intravenous injection of a new iodized oily emulsion.

Hepatosplenography with intravenously injected iodized lipid emulsion has been performed in 30 cases and the results reported. The side effects were minor and transient, as the elimination is rapid. The uptake in the liver was satisfactory and permitted tomography both of the liver and the spleen.
