Abstract
Müller cells in rabbit retina were selectively stained by demonstrating NADH-diaphorase activity. After the sections were measured by light microscopy, the following properties of Müller cells were found: (a) independent of the retinal localization, one Müller cell corresponds with a retinal volume of 15,000 μm3, i.e., with 11 photoreceptor cells, 2 neurons of the inner nuclear layer, and 0.3–1 ganglion cells; (b) the Müller cell population represents about 6.8% of the total retinal volume; (c) the sorbitol accumulation of Müller cells in diabetic retinopathy is said to be unable to cause osmotic damage.
Zusammenfassung
Die Müllerzellen der Kaninchennetzhaut wurden selektiv dargestellt durch den histochemischen Nachweis der NADH-Diaphorase-Aktivität. Nach lichtmikroskopischer Ausmessung der Schnitte wurden folgende Eigenschaften der Müllerzellen gefunden: 1. Unabhängig von ihrer retinalen Lokalisation gehören zu einer Müllerzelle 15000 μm3 Netzhautvolumen; das entspricht 11 Photorezeptoren, 2 Neuronen der inneren Körnerschicht und 0,3–1 Ganglienzellen. 2. Die Population der Müllerzellen repräsentiert etwa 6,8% des retinalen Gesamtvolumens. 3. Es wird diskutiert, daß die Sorbitolakkumulation der Müllerzellen bei der Retinopathia diabetica nicht in der Lage ist, einen osmotischen Zusammenbruch zu verursachen.
