Mastikationseffekt bei unterschiedlichen Gebißformen

Zusammenfassung An Hand von Kaufunktionsprüfungen wurden bei 86 Patienten die Wechselbeziehungen zwischen dem Zerkleinerungsvermögen von Pinienkernen und dem Gebißzustand untersucht. Die Beurteilung des Zahnsystems erfolgte nach folgenden Kriterien: Ausprägungsgrad der Anomalie, Zahl der Kaueinheiten und Antagonistenbeziehungen. Es konnte ein signifikanter Unterschied zwischen dem Zerkleinerungsvermögen des Gebisses und den obigen Kriterien festgestellt werden. Als besonders eindeutig in der Beurteilung erwies sich die Klassifikation nach Antagonistenbeziehungen.

Summary Basing on experiments of the masticatory function 86 patients chewed stone-pine kernels into small pieces and the results, with the state of the occlusion were analysed. The assessment of the occlusion was carried out according to the following criteria: 1. degree of anomaly, 2. number of masticatory units and 3. relationship between opposing teeth. A significant difference was revealed between the degree of pulverization of the kernels and the above criteria. In the analysis the classification of the relationship between antagonists proved to be particularly obvious.

Résumé On a examiné sur une base fonctionnelle la corrélation entre la capacité de mâcher des noyaux de pin et l'état des mâchoires de 86 patients. Le système dentaire est étudié selon les critères suivants: degré de l'anomalie, nombre d'unités masticatrices, relation des antagonistes. Une différence importante est apparue entre la capacité de mastication et les critères énoncés précédemment. C'est la classification selon les relations des antagonistes qui a été particulièrement déterminante dans cette dissemblance.

Incorporation of saturated and CIS- and Trans-unsaturated long chain fatty acids in rat myocytes and increased susceptibility to arrhythmias

Neonatal rat heart myocytes cultured for 3 days in fatty acid-enriched (5 × 10⁵ M stearate, oleate, linoleate, linoelaidate or arachidonate at a 3 : 1, fatty acid (FA/albumin ratio) were analyzed by high-pressure liquid chromatography (HPLC) for the FA content of their neutral lipid, glyco-cardiolipid and phospholipid fractions and were tested for their susceptibility to arrhythmias produced by hypoxic/normoxic medium changes. Increases in the relative amount of FA in the above lipid fractions were generally in the order: elaidate = linoelaidate > linoleate = arachidonate > stearate = oleate. Cell morphology was unaffected by such treatment, but the cultures were more susceptible to induced arrhythmias. Cultures enriched with trans-FA, elaidate or linoelaidate, became markedly arrhythmic; arrhythmias in stearate-enriched cultures were of short duration; whereas the other FA produced intermediate increases. Susceptibility to arrhythmias could not be correlated with polyunsaturated fatty acid (PUFA)/saturated fatty acid (SATFA) ratios of FA in the phospholipid fraction.     

In vitro activity of N-formimidoyl thienamycin and other beta-lactam antibiotics against methicillin-resistant Staphylococcus aureus.

Of 43 isolates of methicillin-resistant Staphylococcus aureus, 90% were inhibited by 8 micrograms or less of N-formimidoyl thienamycin per ml by the agar-dilution technique. Cefamandole, cefotaxime, cefoperazone, moxalactam, and cefsulodin showed relatively poor activity. Vancomycin was the most active compound by weight, inhibiting 93% of strains at 1 microgram/ml.     

Postoperative wound infection: a controlled study of the increased duration of hospital stay and direct cost of hospitalization.

The increased hospital stay and direct cost of hospitalization that resulted from a postoperative wound infection (presence of pus at the incision site) after each of 6 common operations were evaluated. With the aid of the hospital computer, matched controls were obtained with respect to patient age, sex, exact operation performed, clinical service performing operation, pathologic finding, and underlying disease process which might alter the patient's predisposition toward infection. Several of the operations (appendectomy. cholecystectomy, total abdominal hysterectomy, and coronary artery bypass graft) were subtyped in order to obtain equivalence between controls and infected patients. In general, an infection doubles the postoperative stay and significantly increases the hospital expense.
