Effect of long-wave ultraviolet light on the lens. I. Model systems for detecting and measuring effect on the lens in vitro.
نویسنده
چکیده
Rat mouse, and chick lenses incubated with 3-aminotriazole under long-wave ultraviolet (UV) show reduced accumulation and incorporation of leucine and a loss of glutathione. The effect on leucine incorporation is strikingly enhanced when capsule-epithelium pools are incubated. The procedure may identify photosensitizers or metabolic inhibitors which are cataractogenic when acting in conjunction with UV.

Effect of Aqueous Extract of Embelica officinalis on Selenite Induced Cataract in Rats
Cataract is clouding of the eye lens that reduces the amount of incoming light and results in deteriorating vision. Blindness is thought to reach 75 million by 2020. Of these, unoperated cataract may be expected to account for at least 35 million. Thus, the burden of cataract is increasing remorselessly. Embelica officinalis is reported to have a very good antioxidant property and thus we hypot...

متن کاملDevelopment of an Accommodation-Dependent Eye Model and Studying the Effects of Accommodation on Electron and Proton Dose Conversion Coefficients
Introduction International Commission on Radiological Protection (ICRP) has provided a comprehensive discussion on threshold dose for radiation-induced cataract in ICRP publication 116. Accordingly, various parts of the eye lens have different radio-sensitivities. Recently, some studies have been performed to develop a realistic eye model with the aim of providing accurate estimation of fluence...
متن کاملLong-Run Growth of IRAN's Economy from the Lens of Export-Led Growth Model (Application of the Time-Varing Approach)
In 1979, Tirlwall introduced a model called the Balance of Payments Equilibrium (BOPE) model, stating that demand growth could be curbed by the balance of payments deficit, thus limiting further economic growth. The important point in examining the Tirlwall law is the important role of oil exports in providing foreign exchange resources and the important role of these resources in the balance o...
متن کاملDefocusing Effect Studies in MTF of CCD Cameras Based on PSF Measuring Technique
Defocusing effects in modulation transfer function (MTF) measurement of charge coupled device (CCD) cameras is the main focus of current paper. We introduce measuring Point-spread function (PSF) in order to calculate the MTF and further more we will study the shape of MTF and its cut-off frequency by adjusting the lens focusing in different locations. A collimated white light LED by broadband s...
