Summary
Lowry found by quantitative biochemistry in the outer portion of the inner segment a very strong activity of malate dehydrogenase (MDH). On the contrary Princeet al. found by histochemical method relatively small activity in that layer but the highest activity in the ganglion cell layer. The present histochemical study by means of tetrazolium salts (MTT) confirms the strong activity in the outer portion of the inner segment; but in the ganglion cell layer the activity is also relatively strong.
Zusammenfassung
Histochemische Untersuchungen über das Vorkommen der Malatdehydrogenase in der Kaninchenretina konnten die von Lowry in den Außengliedern angegebene relativ hohe Aktivität bestätigen. In der Ganglienzellschicht fand sich eine nicht ganz so hohe Aktivität. Dies entspricht eher den histochemischen Befunden von Prince.
