[Immunopathology of the hepatic damage caused by alcohol. Recent acquisitions].

Recent findings in the pathogenesis of alcoholic liver disease suggest that immunological factors play a leading part in addition to the damaging action of alcohol. Immunological phenomena affected by Mallory's bodies take on considerable importance with respect to humoral immunity. As regards cell immunity, the leucocyte migration inhibition test shows that the lymphocytes of liver-diseased alcoholics can produce the migration inhibiting factor. Deposit of collagen in the liver appears to be induced by lymphocytes sensitized by Mallory's bodies. Recent experimental studies based on the use of collagen synthesis inhibitors (colchicine and penicillamine) may have therapeutic implications.

[Absorbed dose by the crystalline in middle ear tomography (author's transl)].

Measurements of the incident dose on the eye have been taken during the tomographic examinations of the middle ear. These measurements have been effectuated without any protection of the eye, and with a Pb-diaphragm protection, thickness 2mm. The tomograph which has been used is an Italian one (Eurostrator-Zuder, Genoa) provided with complex radiation movements (circular, spiral) and which gives technical resutlts such as the Polytom (generally used for these researches) but which has a focus film distance of 1m instead of 1.40 m. The average incident dose on the erystalline lens is high (11.7 R): the use of the Pb-diaphragm reduces the dose considerably (0.65 R) without any significant imperfections on the radiological image.
