Early sucrose-induced retinal vascular lesions in spontaneously hypertensive rats (SHR) and Wistar Kyoto rats (WKY). 1986

N S More, and N A Rao, and H G Preuss

Retinal capillary basement membrane damage was demonstrated over a relatively short time period (two to three months) by feeding a diet containing high amounts of sucrose to spontaneously hypertensive rats (SHR) and their normotensive controls, Wistar Kyoto rats (WKY). Similar changes did not occur in SHR and WKY on a high starch diet. The early damage to the capillaries consisted of thickening of capillary basement membranes, loss of homogeneity, and inclusions containing debris. Previous studies on sucrose-induced eye lesions have reported chronic pathological changes only after prolonged periods of heavy sucrose ingestion, usually exceeding one year. Accordingly, the temporally foreshortened experimental pathogenesis offered by the SHR/WKY model allowed us to examine early changes in sucrose-induced vascular eye lesions.

UI MeSH Term Description Entries
D008297 Male Males
D008854 Microscopy, Electron Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen. Electron Microscopy
