Zusammenfassung

Tierexperimente haben gezeigt, daß mit Unterernährung bzw. Eiweißmangel ein Aktivitätsanstieg der Gewebe-Ribonuclease (RNase, E.C.3.1.4.22) einhergeht. Die ursächlichen intrazellulären Veränderungen sind unbekannt. Unter der Annahme, daß sich die erhöhten Enzymaktivitäten der Gewebe im Serum widerspiegeln, untersuchten wir die Serum-RNase-Aktivität bei 10 gesunden Versuchspersonen unter normaler Ernährung (Gruppe I), bei 7 Patienten mit langdauernder parenteraler Ernährung (Gruppe II), bei 13 Patienten aus dem chronischen Hämodialyseprogramm (Gruppe III) und bei 9 Patienten mit akuter Pankreatitis (Gruppe IV). In Gruppe I betrug die RNase-Aktivität im Serum 195,3±58,8 U/ml. Bei Gruppe II (314,6±95,3 U/ml) und Gruppe III (374,1±102,1 U/ml) lag sie signifikant (p<0,005) höher; zu Gruppe IV (295,1±191,8 U/ml) bestand kein Unterschied.

Summary

Animal experiments have shown that malnutrition and protein deficiency states, respectively are associated with elevated tissue ribonuclease (RNase, E.C.3.1.4.22) activities. The causal intracellular alterations are unknown. Assuming that increased tissue RNase activities are reflected by serum levels, a study was made of the serum RNase activities in 10 healthy controls eating a normal diet (group I), 7 patients on long-term parenteral nutrition (group II), 13 chronic hemodialysis patients (group III), and 9 patients with acute pancreatitis (group IV). In group I the serum RNase activity corresponded to 195.3±58.8 U/ml. A significant (p<0.005) elevation was noted in groups II (314.6±95.3 U/ml) and III (374.1±102.1 U/ml), no difference being detected in group IV (295.1±191.8 U/ml).
