[Demonstration of the hepatic veins by echotomography (author's transl)].

Provided that a rigourous protocol is adopted, exploration of the hepatic veins by echotomography (grey scale) is practically always possible. It should be integrated into every echotomographic study of the liver (parenchyma, biliary tract, portal system and inferior vena cava). The findings cover a narrow range: hepatic veins free, compressed or not visible. This method is harmless, rapid, reproducible and inexpensive.

Infrared linear dichroism investigations of deoxyribonucleic complexes with histones H2B and H3.

Complexes between DNA and histones H2B and H3 were studies by means of infrared linear dichroism in a wide range of histone to DNA ratios and of different relative humidities. The measurement of the dichroic ratios allows one to determine the secondary structure of DNA in the complexes. It is shown that the progressive addition of histone H2B or H3 to DNA inhibits the structural B leads to A transition and DNA remains in a B-type form at low relative humidity. A new simple method is proposed to evaluate the amount of A or B forms of DNA when both structures are present. It is found that the B leads to A transition is fully inhibited when only one molecule of H2B or H3 histone is bound per about three or four turns of DNA helix, respectively. It is proposed that about four to three turns of DNA helix represent the "critical length of DNA" (minimum "cooperative unit") for the B leads to A transition.

[Atypical angiographic appearances of aneurisms of the abdominal aorta (author's transl)].

On the basis of 72 radio-surgical cases of abdominal aortic aneurism, the authors stress the value of atypical angiographic findings, which are ten in number. The presence of clot within the aneurism itself may explain a disparity between radiological and surgical findings. Failure to recognize these atypical signs is very serious, when the diagnosis of aneurism is not suspected clinically. Antero-posterior and, above all, lateral abdominal aortography is essential in the angiographic study of aneurisms of the abdominal aorta. Careful search for these 10 atypical signs should make it possible to avoid missing latent aneurisms. Lateral abdominal aortography is essential in order to determine the state of the abdominal collaterals of the aorta and, in particular, the superior mesenteric artery.
