No consequence of dietary omega-3 polyunsaturated fatty acid deficiency on the severity of scopolamine-induced dry eye
2008
International audience; Purpose:Epidemiological studies suggest that dietary omega-3 polyunsaturated fatty acids (PUFAs) may protect against prevalence of dry eye. This work aimed to evaluate whether a dietary deficiency in omega-3 PUFAs may increase the severity of dry eye in a scopolamine-induced rat model. Methods:Three consecutive generations of Lewis rats were bred under diets deprived of omega-3 PUFAs. Dry eye was experimentally induced by continuous scopolamine delivery in female animals from the third deficient generation and in female Lewis rats fed for three generations with a balanced diet. After 14 days of treatment, the clinical signs of ocular dryness were evaluated in vivo us…
Dietary prevention of visual function and cognitive decline by omega-3 polyunsaturated fatty acids in Senescence Accelerated Mouse P8 (SAM P8)
2008
International audience; Purpose: : Neuronal tissues such as the brain and the retina contain elevated amounts of long-chain omega-3 polyunsaturated fatty acids (PUFAs) and particularly docosahexaenoic acid (DHA). DHA concentrations are known to decrease in the aging brain and are associated with cognitive decline. The senescence-accelerated mouse prone 8 (SAM P8) is a mouse model for aging that exhibits deficits in cognitive performances as well as alterations of retinal functionality (ARVO 2004 E-abstract 797). The aim of this study was to evaluate the effects of a dietary supplementation with DHA on mood, cognition and visual functionality of SAM P8 during aging. Methods: : SAM P8 mice we…
Alteration of plasmalogens in erythrocytes of patients with diabetic retinopathy
2011
Purpose Plasmalogens are phospholipids characterized by a vinyl ether bond and the preferential esterification of polyunsaturated fatty acids (PUFA). We have shown that the lack of plasmalogens leads to abnormal retinal vascularisation. Because we hypothesize that plasmalogens are negative regulators of vascular development, we aimed to check their circulating levels in patients having a retinal pathology with vascular proliferation. Methods Blood samples were collected from 4 control subjects and 42 patients having proliferative or non-proliferative diabetic retinopathy (DR). Patients were classified according to the stage of DR. The plasmalogen content and the fatty acid composition of er…
