The distribution of nucleic acid chromophores at cellulose-water interfaces. 1. Photometric parameters.

A computer-assisted calculus of the chromophores distribution in the contiguous layer around the scattering centers of a multiple scattering medium, using bichromate photometric data and an extended Kubelka-Munk expression, was developed. Explanatory examples of nucleic acid impregnated chromatography paper disks show the efficiency of the method proposed for the study of macromolecular structures and the dependence upon the physico-chemical peculiarities of the solutions used.

[Incomplete chronic duodenal stenosis caused by compression by the aorta and mesenteric artery].

In the light of data from the literature, as well as on the personal observations made in 5 cases of chronic, imcomplete duodenal stenosis through aortic-mesenteric pincers that have been hospitalized and operated, the authors stress: the complexity of the syndrome, the difficulties encountered in the establishment of the diagnosis, the severe consequences of the evolution, the necessity to apply surgical treatment as soon as possible.
