Enzymaktivitäts- und Verteilungsmuster im Rattenovar während der infantilen und juvenilen Entwicklungsperiode

Summary

In ovaries of rats the alterations of enzyme activities between the 5^th and 60^th day of life were studied by quantitative biochemical analysis in tissue extract. Furthermore oxydoreductases were localized by means of histochemical technique. The activities of enzymes of the aerobic glycolysis per g fresh weight increase continually while the activities of lactic dehydrogenase and enzymes of the citric acid cycle are slightly decreasing. The activity of NADPH-supplying glucose-6-phosphat dehydrogenase shows a striking rise between the 5^th and 15^th resp. 45^th and 60^th day of life. The increase of activities in the development of the infantile ovary and differentiation of the interstitial cells are coincident with the first maximum of LH-production.
