Abstract

Cataract and retinopathy remain the preventable cause of blindness worldwide, and many pharmacological strategies have been proposed for the treatment of these eye diseases. Animal models play an important role in understanding the pathophysiological features of eye disease and developing for a new therapy. In this study, we investigated the development of cataract and retinal lesion with diabetes using an obese type 2 diabetic models SDT fatty rat. Macroscopic analysis in eyes was performed from 16 to 24 weeks of age and histological analysis was performed at 24 weeks of age. As a result, the lens cloudiness was observed from 19 weeks of age and the degree of the cloudiness was more progressed until 24 weeks of age. Histopathological findings, such as degeneration of lens fiber and shortening and irregular arrangement of cone and rod in retinal tissue, were observed at 24 weeks of age. In conclusion, SDT fatty rats may be useful to understand the pathological features in diabetic cataract and retinopathy develop a new therapy for the disease.

Abstract

Postmenopausal women are at a higher risk of developing diabetes, and estrogen can lower blood glucose levels. The purpose of this study was to investigate the effect of ovariectomy (OVX) on the pathology of diabetic nephropathy. Female SD rats and SDT fatty rat underwent bilateral OVX or sham treatment at 6 weeks of age, and their blood and kidneys were collected at 40 weeks of age for blood biochemical and histopathological analyses. OVX treatment resulted in a decrease in blood estradiol levels at 24 and 40 weeks of age. Histopathological analysis revealed that Sham-treated SDT fatty rats showed glomerular atrophy, adhesions, enlargement, mesangial cell proliferation, regenerated tubules, hyaline casts, Armani-Ebstein lesions, tubular dilatation, interstitial inflammatory cell infiltration, and fibrosis. OVX treatment slightly reduced glomerular atrophy and enlargement, renal tubular dilatation, and interstitial inflammatory cell infiltration, while slightly increased or exacerbated mesangial cell hyperplasia, tubular regeneration, and Armani-Ebstein lesions. The above findings suggest that SDT fatty rats are not a practical model to study postmenopausal diabetic nephropathy.
