[Hemorrhagic accidents in palatal tonsil surgery]. / Accidente hemoragice in chirurgia amigdalei palatine.

Here is shown that, even though tonsillectomy is the most frequently performed operation in ORL, it may sometimes cause severe hemorrhaging that could imperil the patient's life if not rapidly and competently dealt with. Tonsil hemorrhaging is favoured by the anatomical situating, tonsils being greatly vascularized, as well as by the specific of the pharyngeal wounds. There are discussed here the cases in the Bistrita ORL Clinic between 1981-1987.

The role of increased Ca++ influx as a possible additional adaptive mechanism in experimental left ventricular hypertrophy (exp LVH).

Membrane potentials, isometric contraction and autohistoradiography with 45Ca in papillary muscle of rats with experimental LVH without cardiac failure as compared with sham-operated animals proved an increased Ca influx per beat and a Ca accumulation at or near the sarcolemma. This phenomenon is regarded as an additional mechanism for the improvement of the cardiac performance in the compensatory stage of the experimental LVH without cardiac failure.
